Sorry your browser is not supported!

sorry for not beeing able to respond any sooner - I'm not realy sorting the array based directly on the values it holds - more like the array holds some memory pointers, and I want that batch of pointers in the individual item referred to in an sertain order.
The problem for me is to insert, move the individual structures, and then delete the original entry, rather than just say 'move item X to position Y'

'Delete and insert' together in an array sound very like 'move and update' to me, and that can be done with a single ROTATE ARRAY like so:

dim a(10) as integer

for i = 0 to 10
    a(i) = i
next

print "Initial array"
DisplayArray()
print

print "Move 2 to 7"
MoveArrayItem(2, 7)
DisplayArray()
print

print "Move 6 to 4"
MoveArrayItem(6, 4)
DisplayArray()

wait key
end

function MoveArrayItem(Item as integer, Position as integer)
    if Item = Position then exitfunction
    if Item < Position
        Direction = 1
    else
        Direction = -1
    endif
    rotate array a(), Direction, min(Item, Position), max(Item, Position)
endfunction

function DisplayArray()
    for i = 0 to 10
        print i; " - "; a(i)
    next
endfunction

It's still up to you to search the array to find the original item you want to delete and where it should be inserted though.

If this isn't anything like you are aiming for, then you need to provide more information on what you are doing and what you want to accomplish.

I just downloaded and installed the entire package. I can't wait to get into this a n poke around.

I'm hoping I can make stuff a little easier with this entire suite of add-ons and plug-ins.

I am in the process of rewriting some Think Pascal source (from Macintosh) into DBPro. It works, but it needs more work...

Hopefully, I can get it completely converted, and add some needed stuff that I have requests for. Thanks for this great package.

--If you're looking to upgrade this, please do so! There may be a few bits that are a bit odd to use, but I will see what I can manage.

Matrix1Util_30 - 1.1.0.2
Matrix1Util_32 - 1.1.0.1
Matrix1Util_33 - 1.0.0.2

There is one command in there that I haven't been able to test personally and I'd be grateful if someone could do this for me as I was kind of coding blind with it - it's the WINDOWS IS 64 BIT() function.

As you can see from the code, you load and save arrays via my datafile commands - sorry but the commands LOAD ARRAY and SAVE ARRAY were already taken. Doing it this way also allows you to save multiple arrays of different formats to the same file, rather than having one file per array as DBPro provides by default.

There are several things to note:
- The DBPro saved array format is completely different to the saved array format I've constructed, so you can't save an array with the built-in command and load it using the new commands.
- An array has to be dimensioned before you can load or save the array, even if you give it no elements. This is due to the fact that the array has no 'type' within the runtime until it is dimensioned, and until it has type, there's no way to set up the array with the correct amount of storage. If you try to do this, the plug-in will throw up an error telling you what's wrong.

The last release also added another new function callback - you can now intercept the DBPro window messages before DBPro get them, take some action on the message, then either decide to allow the message to continue to be delivered to DBPro, or stopped.

Here's an example that captures the close message that is caused when the close icon is clicked:

sync on
sync rate 0

set message callback "WndProc"

yinc = text height("|")

repeat
   box 0, 0, screen width(), yinc * 3.5, 0xff000000
   text 0, 0, "Press SPACE to disable the callback"
   text 0, yinc, "Press ENTER to enable the callback"
   text 0, yinc + yinc, "Press ESCAPE to end the program"
   
   if spacekey() then set message callback ""
   if returnkey() then set message callback "WndProc"

   sync
until escapekey()

set message callback ""

end

#constant WM_CLOSE   0x0010

function WndProc(hwnd as dword, msg as dword, wparam as dword, lparam as dword)
   print hwnd; " - "; msg; " - "; wparam; " - "; lparam
   if msg = WM_CLOSE
      stop current message
   endif
endfunction 0

Other things you could do include:
Capture all keypresses to provide a customised input system.
Capture the windows move message to stop the window being moved, or to limit its movement to a fixed area.
Capture resize messages to stop the window being resized.

A possible future enhancement is the interception of messages from other 'windows' related to your program, so make sure that you use the HWND parameter in your function to confirm you are getting messages for the window you think you are (for instance, use the GET DBPRO WINDOW() function).

When a DBPro window is being dragged it does not run. This is very bad if that user is the host of a multiplayer game and throws off timing routines. Is this something that can be worked around with this new addition?

@ IanM,

This is brilliant. Thanks v much.

The load and save array with UDT functionality is excellent.

Assuming cant do UDTs on UDTs (etc) on arrays or multi dimensional yet? Just checking. Still amazingly useful.

thanks again

[edit]

Fix Object Scale - does it set an object of whatever size to 1.0?

The save/load commands will handle UDT's of any complexity, and arrays of any number of dimensions (up to DBPro's limit of 9 dimensions).

The fix object scale will apply the scaling that has been applied to the object and its limbs to the limb meshes and limb offsets, then it will reset all the scales back to 100% at all levels.

@ IanM,

Why is there a difference between:-

open datafile to write 1, "MySimpleArray.dat"
save array to datafile MySimpleArray(), 1
close datafile 1

and

open datafile to write 1, "MyStringArray.dat"
save arrayptr to datafile get arrayptr( MyStringArray() ), 1
close datafile 1

why cant you save array to datafile MyStringArray(), 1 ? is it because the array in the second one has strings in it?

how would you save say a multi dimensional array LandsArray(10,10)

where it was dimmed as an array as type Landy

and Landy carried a number of strings and integers?

I suppose the easiest thing would be if you could just post some code about how to save and load a multi dimensional array with a udt with perhaps a/some udts on that where within the udts there were some strings? (no need to post in the code any of the data, just so dumkopfs like me get the idea)?

No, don't read so much into the code

Firstly, that code was mostly put together from the pieces of code I used to test the new functionality.

Every time I add a new array command, and if it's appropriate, I also add an equivalent to do the same for an array pointer too. That's the only reason I had for using the arrayptr versions of the commands - you don't have to use them at all.

The only reason that I picked strings in particular was because strings are handled slightly differently than straight numbers in DBPro and I wanted to specifically test for those to make sure they were handled correctly.

[EDIT]
Oops, missed most of your questions

You don't need to do anything special to save a multi-dimensional array, whether it contains a UDT or a single data type:

dim a(1, 2, 3, 4, 5) as YourType
open datafile to write 1, "test.dat"
save array to datafile a(), 1
close datafile 1

When you load it, you do exactly the same (except open to read and load array) and the array will be recreated in all its dimensions - you don't even need to presize it or specify the dimensions:

dim a() as YourType     ` No dimensions at all
open datafile to read 1, "test.dat"
load array from datafile a(), 1
close datafile 1

See? You don't need to do anything different at all.

@ IanM,

Thanks for getting back so quickly. Phew. That's a relief. I'm off to put those commands through their paces.

These load and save array to/from datafile commands deserve mention in the next newsletter...

@ IanM,

What if I save an array using these commands in one program and then load the same array in another program - what happens to the UDTs associated with the array? Do I have to do the type command for the udts in that second program too before I load in the array or does the load command load in the relevant udts as well as the array?

Just occurred to me, sorry.

Yes.
The UDT's have to have the same internal size and layout for you to load them. That's part of the reason why the arrays have to be dimensioned before you can load data into them.

Nope:

Quote: "Normal protection provided by the Berne Convention is life of the author plus fifty years from death ... Under UK copyright law for example, the copyright duration is typically 70 years from the end of the calendar year in which the last remaining author of the work dies."

That basically means that it doesn't matter what year I put in the notices, I've simply got 50 or 70 years of extra copyright protection after I die.

Is that a brain-dead law or what?

Hey IanM,

I was working on a project yesterday and I needed a card shuffling routine. I noticed you don't have a RANDOMIZE ARRAY function. Could this possibly be implemented in a future release as I can see its useful potential.

There is no rush however as I quickly coded my own shuffling routine in DBP but i'm pretty sure its much more trivial in c++

Two reasons I've not provided that:
- What random number generator should I use (the DBPro one, or one of mine ... and which one of those)?
- It's easy to code your own

and one reason that I should:
- Despite it being easy, most people code it incorrectly, mucking up the final distribution.

Here's a correct solution to the problem:

for i = array count( a() ) to 1 step -1
   swap array items a(), i, rnd(i)
next

Yep, I used the same algorithm for my shuffling routine.
My project has now moved on to the GDK, which means I can't use you're great DLLS

Your signature has been erased by a mod because it's larger than 600x120

Hi Ian,

I'd like to use your sort array command instead of my crude out-of-place array sort. Yours is only 2000x faster . . .

But I need to know for sure, is your sorting algorithm stable (as in , http://en.wikipedia.org/wiki/Category:Stable_sorts)?

Also, does this command work on float fields?

Using the default setting, sorting is not stable, however you can switch to using the merge sort on your array which is.

http://www.matrix1.demon.co.uk/Matrix1Utils_Help/Matrix1Util_29/set_array_sort.html

Or you can stay with the faster introsort and include an extra field to include last in your list of fields to sort to maintain the stability.

All of DBPro's standard types are accepted and treated correctly, except see the sort command for 'special' rules on strings, which I may also make optional at some point.

Any known issues with the Hex to Decimal command?

I was using it today in my program and it seems to have caused the subroutine that it was being used in to lose it's pointer to it's return point. As soon as it hit the return statement it crashes to the "Your program has an error and must be shut down... blah, blah..." message box.

Quick question on your draw to commands.

Quote: "Drawable = IMAGE ALLOWS RENDER ( Image Number )"

What makes an image drawable? I am making a minimap of sorts for my game. I take the map, make an image from it, resize it to a standard size (make a bitmap, make a sprite, resize sprite, paste sprite, get image) and now I want to paste other images (start location, home location) to this new image and I am being told the image is not a render target.

If you need more detail on how the image is created let me know.

Images can only be drawn to if created using 'set camera to image' or the command from IanM's plugin.

Found a way around the renderable image problem:

function Make_Image_Renderable(Image)
  cb = current bitmap()
  ni = find free image()
  make image ni,image width(Image), image height(Image)
  draw to image ni
  paste image Image,0,0
  delete image Image
  make image Image,image width(ni), image height(ni)
  draw to image Image
  paste image ni,0,0
  delete image ni
  set current bitmap cb
endfunction

May not be pretty, but it works.... /shrug

Hey Ian, I tried using your File IO plugin for file i/o bu whenever I use datafile datastring or datafile string$ the plugin crashes with a generic "This program has encountered a problem and needs to close" type of error. The module name in the upper right being your .dll.

The code was:

if file exist("Layout.txt")
open datafile to read 1,"Layout.txt" //works fine
iotemp$=datafile string$(1) //fails
iotemp$=datafile datastring(1,146) //fails
close datafile 1

print iotemp$

endif

Layout.txt is just a plain text file with 0's and 1's. Any insight?

Edit:My DBPro version is 7.4 and I'm using your latest update.

Perhaps you could send me a copy of the layout.txt file, as I can't currently reproduce your problem.

@GIDustin,

Quote: "make a bitmap, make a sprite, resize sprite, paste sprite, get image"

Make a renderable image, make a sprite, resize a sprite, paste a sprite. Job done.

Basically, the original point of renderable images was to avoid those slow GET IMAGE commands.

Can you send or upload the actual file. I have no problems with the data, so the problem may be with line endings or 'invisible' characters.

Ian:

Your "find free memblock()" command returns a value from 1-256 according to help files, but only 1-255 are valid. On a few instances it has returned 256 and crashes my game. I can avoid it by using the optional parameters and setting my own limits, but I thought you should know.

Thanks!

Edit: Been trying to reproduce the problem but I cant seem to... If I ever had memblock commands fail, I just re-compile the same project and it goes away. Not sure how your commands randomly pick numbers, but my test project finds free memblocks in the exact same order every time I compile/run it... Not sure how a 256 got in the list earlier...

As far as I can tell, that function works correctly.

Here I get 256 memblocks created using FIND FREE MEMBLOCK, then try and allocate one more - the report should be that all memblocks were created correctly:

` Use up all memblocks
for x = 1 to 256
   i = find free memblock()
   exit prompt "Memblock " + str$(i) + " failed", "ERROR"
   make memblock i, 10
next

` Try and allocate a memblock - if returns non-zero value, then something's gone wrong
i = find free memblock()
if i
   exit prompt "Memblock " + str$(i) + " is available!", "ERROR"
else
   exit prompt "All memblocks created correctly", "DONE"
endif

end

In actual fact, it's OK to create a memblock with an ID of 257 too, which that function doesn't take account of.

@Dar13,
Sorry, still can't reproduce the problem.

Here's the code I used with your file:

if file exist("Layout.txt")
   open datafile to read 1, "Layout.txt"

   do
      iotemp$ = datafile string$(1)

      if datafile end(1) = 1 then exit

      print iotemp$
   loop

   close datafile 1

endif

print "DONE"

wait key
end

About the only thing that I can think of is that the correct runtime libraries may not be included on your system. Check in your windows System32 directory for the files msvcp71.dll and msvcr71.dll - if one or both are not there, then you should download the last link in the first post of this thread and extract the contents of the zip file into your system32 directory.

I had found one of your .dll's that was intended to load files on a seprate thread. But it doesn't work with the newer versions of DBP. Is it included in this pack? or gone?

Yet another request if you have the time. Is there any way to see your current location within a file when using "open to read"? Is this something that you could gain access to? Like a "position in file <FileNum>".

I would be using it when loading a large map file to display the load percent to the user. If the file was simply bytes and longs you could easily calculate it, but there are strings and memblocks as well which make it only slightly more difficult. Access to the variable that holds this information anyway would alleviate some time and calculations.

Did you mean OPEN TO READ, or OPEN DATAFILE TO READ?

If it's the first, then no, there's no way to know your current file position within DBPro's file handling.

If it's the second, then yes, naturally I'd include something like that within my own file handling.

If you are using DBPro's built-in file handling, I'd suggest switching over to using mine instead. It's a lot faster, a more complete implementation, and it's not difficult to switch either.

I was using OPEN TO READ. Your datafile commands look like they could work, although there are some missing commands there too. I am using WRITE MEMBLOCK and READ MEMBLOCK to add images/sounds into the file as well. Is this a possible addon for later? I could rewrite the routine to just save the memblock size, and then save byte-by-byte too I suppose...

The missing commands are due to me ducking some of the issues involved and providing a catch-all command. You can implement memblock and memory bank saving using the WRITE DATAFILE MEMORY and DATAFILE MEMORY commands.

` Create a memblock & fill it with data
make memblock 1, 256
for i = 0 to 255
   write memblock byte 1, i, i
next


` Write the memblock to a datafile
open datafile to write 1, "data.dat"
write datafile dword 1, get memblock size(1)
write datafile memory 1, get memblock ptr(1), get memblock size(1)
close datafile 1


` Read a memblock from the datafile
open datafile to read 1, "data.dat"
make memblock 2, datafile dword(1)
BytesRead = datafile memory(1, get memblock ptr(2), get memblock size(2))
close datafile 1


` Compare the two memblocks
Error = 0
for i = 0 to 255
   if memblock byte(1, i) <> memblock byte(2, i) then inc Error
next

if Error > 0
   print "Errors were detected"
endif

print "Complete"

wait key

Currently you could save memblocks, banks and memory addresses, and for memblocks and banks you could save partial data from them, so that's why I ducked the issue and just provided the basic tool of memory addresses.

Ian,

Is it correct that not all the keyword (for syntax highlighting) and helpfiles are updated?

I have succesfully implemented the new feature to capture the close button (many thanks for that btw!), but the commands don't light up in the editor nor are there any helpfiles for them.

If there are missing keywords or helpfiles then that's a bug. Refresh your keyword list in the editor, and if the problem still occurs, let me know which particular commands/function are missing and I'll fix it in the next release.

I didn't know I had to use rebuild keywords. In previous updates the editor would automatically update the keywords on startup. I noticed that it did not do this this time.

I found the new commands for saving UDT arrays in the helpfiles but not the commands for capturing windows messages (but I guess now I didn't know where to look for them, and that they were probably already there).

I used rebuild keywords and everything is ok now.
Thanks!

I wouldn't call it a bug, but it appears that UNQUOTE$() does not remove left/right (open/close) double quotes, only neutral double quotes.

s as string : s1 as string : s2 as string
set text font "Arial" : set text size 24

s = "ABC"
print "Test String: ";s

Rem add neutral double quotes
s1 = Quote$(s)
print
print "With neutral double quotes: ";s1
print "Unquote$() applied: ";unquote$(s1)

Rem add left/right double quotes instead
s2 = chr$(147) + s + chr$(148)
print
print "With left/right double quotes: ";s2
print "Unquote$() applied: ";unquote$(s2)

Rem Workaround
Print "Workaround using nested Remove All$(): ";
print Remove All$(Remove All$(Remove All$(s2, chr$(34)),chr$(147)),chr$(148))

sync
wait key
