laodimage of resouce/IDB_BITMAP?

[onkelhotte]

Hi there,

in my QuickWin App I load a .bmp and display it with loadimage_w. But I have to use a path/filename and to distribute the .bmp with my program.

Is there a way to display an resource bitmap, something like loadimage_w(IDB_BITMAP1,x,y)? I tried to use GetResourceTypeName, but I couldnt find the apropriate module where it is defined...

Thanks in advance,

Markus

Here are some replies to a recent similarquery on COMP.OS.MS-WINDOWS.PROGRAMMER.WIN32 NEWSGROUP about how to add bitmap files as resources to an executable. Although the answers are C++-oriented, the windows API routines are callable from CVF/IVF I believe.There are some useful links in the first reply.Hope they help.

Im getting closesolving my problem.

In my code I load a bitmap file via loadimage_w to display it in an QuickWin Window. But the
disadvantage is, that I have to deliver the .bmp file with my program. So I included it in the
Resource Editor and try to load it from there. Because QuickWin does only allow to load
images from file, I try to save the Resource Bitmap in a file:

Code:

hBmp=FindResource(GetModuleHandle(NULL),245,RT_BITMAP)
hSize=SizeofResource(NULL,hBmp)
hRes=LoadResource(NULL,hBmp)
hLock=LockResource(hRes)
hFile=CreateFile(tempstring,GENERIC_WRITE,null,null,CREATE_ALWAYS,FILE_ATTRIBUTE_NORMAL,null)
l=WriteFile(hFile,hLock,hSize,loc(byteswritten),null)
l=SetEndOfFile(hFile)
l=CloseHandle(hFile)

That does nearly the trick. A new file was created.
The code of my two bitmaps are identical, but the new file misses the bmp header I think.

Original file begins with:
BM v ( A 8

New file begins with:
( A 8

Or would be another way to copy the resource bitmap into memory and paste it the putimage on the QuickQin dialog?

When you insert the bitmap as "resource", the file header is indeed stripped off (a .bmp file consists of a small header plus series of bits which represent the data in memory). Instead of adding it as "bitmap", you should add it as a "bitstream" (custom resource). See this thread.

Or, better still, drop the QuickWin altogether :-). See also this xeffort sample.

Getting rid of QuickWin *sigh* I dont exaggerate when I say that sometimes I dreamt of it at night :-)
Our company will move to VS2005 at the beginning of the next year, so I only have to use QuickWin for another 6 months.

Thanks, your link/example works fine. They always do!
