BUMP: I really need to know how to handle cursors and bitmaps from my .rc resource script. If you have any insight, please let me hear it!

I'm not sure that you will be able to do this. To change the cursor you need to handle the WM_CURSOR message in the Windows message loop. This is encapsulated by the LoopGDK() function and therefore not available to intercept (someone please correct me if I'm wrong on this). Could you not use a sprite instead?

Well, thats what i'm using. I don't need to use a .cur file, I could use .BMP too. The problem is, how do I use dbSprite to load from a resource?

I have been pondering over this too. I don't think it can be done directly because dbSprite takes an image number as one of its parameters. The image number should have been assigned by a call to dbLoadImage which takes a filename as one of its parameters, hence the problem. One way that I've been trying to do it goes like this:

1) Use the Windows API calls FindResource and LoadResource to get at the image. So far my attempts to get this working have failed, the FindResource function doesn't seem to work in a DarkGDK application.

2) Create a memblock using dbMakeMemblock

3) Copy the previously loaded resource data into the memblock

4) Make an image from the memblock with dbMakeImageFromMemblock. The image should then have an image number associated with it.

5) Use the image number as a parameter for dbSprite.

Like I said, so far I've failed at step 1) but if you can get it working, please let me know.

hi , try this code which ianm posted when i asked the same question.

http://forum.thegamecreators.com/?m=forum_view&t=119287&b=22

Also i did some code after ianm said u could load it in with directx and then use the make image command in the gdk , but this didn`t seem to work so i had to use get image instead .

http://forum.thegamecreators.com/?m=forum_view&t=125878&b=6

Hope that helps.

Edit: I also have some code somewhere to load wav files from resources too.

IanM's code is fine for loading bitmaps of the .bmp type, I have used it myself in a project. However the LoadBitmap() function can't handle other formats such as .png or .jpg which is what I was trying to do with FindResource() and LoadResource(). These two functions should (in theory) allow you to load any type of resource, including custom defined resources.

try the directx loading route as d3dx textures allows directly loading from resources in all the formats dgdk supports , then use dbMakeImage() to convert it to a format gdk can use , this seems like an easier way to me.

I will post some code up tommoro .
