Hey, I'd like to know is that a way to able to do the linking function. Basically I want to create a "menu" that can link to 2 optional program, and the users are able to go back to "menu" through a keyboard input,such as "esc" which without closing or open another windows. The function of the "menu" is let the users able to switch from one world to another.

Hope you can understand what i meant here..

Thanks for your kindly helps..

Yes. But is there any way to open the execute in the same windows?

How to bring the variable(entities number) to the next exe?

Thanks..

One way is to save an the values to array then load it back in the new running program.

@IanM: I'll save you the trouble;

@fumade: You could always take a look at mr. Mold's Matrix1Utilities collection; the shared memory banks it offers could likely do what you want.

I use IanM's memory banks with VB, they work very well. Add the Mutex commands, and you ensure that everything closes down amicably if anything goes wrong.

I'm not sure that you guys have answered the whole question - using a shared memory bank covers the communication aspect of the problem, but not the 'without closing or open another window' part.

You can get the menu programs window handle and pass it to the new programs on the command line when you kick them off. but is there a way to get the new DBPro program to use that window? Or is there a hack to allow you to position the new window exactly over the old window (I remember someone did something like this to correctly render a screensaver in preview mode)?

You need to open a bank for shared memory as well:

IanM, I'd like to confirm the code with u.

"mybank" is referred to account name i create for this entities memory only or can use wider?
"1" is the represent account number for mybank?
"4096" only for 1 memory(entities) if more than 1, have to use bigger num?

"1" is the one for my account number?
"0" is represent the "entities"?

Thanks...

Regarding your last post; you should declare A and B as floats / doubles, or they will only hold the integer part of whatever you try to put in them, which you probably don't want when dividing by large numbers such as 1000.

Try to slap this in before your snippet


You could also replace A and B with A# respective B#; that will make them floats. I think it is only the single-precision type though.

'It doesn't work' is not a great bug report

Attached is a quick example to show that it does work.

what i meant is the entities at the 2nd program is 0...after i enter 10 at the menu program..

i just run some tried on it. if i use wait key command after the execute file, it will be ok. if not, the entities on the next program is 0.


but the program is i want to close the menu program..

Check my code - I use the 'wait' flag on the execute statement, so that the first program waits for the executed program to finish before it moves on.

The biggest difference between you and me (for DBPro at least ) and in my opinion, the more experienced users of DBPro and the newcomers, is that we've tried and failed at more stuff than you have.

If I don't know something and I think I need to know it, I try it out and see for myself.

Admittedly, your first question is a good one to ask on the forums, but your last one ...

Quote: "is that the "get dir$()" is necessary for the "other.exe" to run?"


... this is something you can answer yourself with a few minutes work, rather than wait for an answer for almost half a day on the forums.

So try it out, and let us know

maybe u r right. so sorry to disappoint u again, i cant find any different btw the "" and get dir$() in the directory argument. but if there is no different,why u want to put a long command instead of "". maybe i not tried hard enough..

Basically, you specify the path where the file to be executed resides. If it is in the CWD (current working directory) of the app that calls the command, you don't need to specify a path at all. Likewise, should it be in one of the subfolders of where your running program is located, you only need to specify the relative path (ie. execute file "stuff.exe", "executables", "", 0).
Finally, it works just as well to put the full path to the exe straight in the first string parameter (ie. execute file "executables\\stuff.exe", "", "", 0). I believe that whatever you specify as the path parameter is from where the executed file will have it's CWD set at startup though, so not thinking carefully about this and then loading stuff from the second program could potentially cause problems (as it might link to a subfolder that doesn't exist or contain the proper files).

Thanks Rudolpho,basically i understood this from the html code, want i really confuse is that the get dir$() is look same as the "". correct me if i am wrong, "" in there meant nth, that nth will not bring the execute file from anywhere starting from CWD then it will execute the file from CDW. while the get dir$() is getting the absolute path of the CWD. so both are the same, in order to make life easier, why have to trouble with the long command?!

Rudolpho, thanks for your detail explanation.

You asked why I did that - I did that because I didn't know and didn't want to spend the time to find out if they would have different effects. It was quicker and easier for me to type the few extra characters than to create new projects to find out.

My earlier point was that if you want to know what the difference actually is, test it, try it, find out. That's what I do.

IanM, thanks for your explanation. sometimes i just want to know more and detail for doing somethings, epically those i feel interest on it. so sorry to spam the topic with a lot of question, mayb i should tried harder before i post any questions. for your information, i did try on most of the things in order to solve my problems, maybe not hard enough.

Thanks for all of your concern and i really appreciate it...
