LibFunc and Windows API

[Aleu]

First I'd like to thank mtettmar for the helpful reply. It's some strange I can't reply to my last post, so I open a new.

LibFunc is really useful! I wonder whether MS can call all the Windows API functions?

I tried another api to paste one bmp file on another:
LibFunc>gdi32.dll,BitBlt,r,c:\1.bmp,x,y,320,240,c:\2.bmp,0,0,SRCCOPY

Here's the function definition:
BOOL BitBlt (HDC hdcDest,int nXDest,int nYDest,int nWidth,int nHeight,HDC hdcSrc,int nXSrc,int nYSrc,DWORD dwRop)

What am I wrong?

p.s. MS seems not so powerful dealing with pictures. ImageMagick is. Is it possible for MS to use ImageMagick function?

Yes, MacroScheduler + ImageMagick is a great combination, I use it a lot.

I think I have posted some examples on this forum, one is in this thread.

That function is saying it wants a handle to a device context (HDC) for the destination and the source. But you are specifying a filename.

Ok, to get a file's handle:

LibFunc>kernel32.dll,CreateFile,FileHandle,C:\1.bmp,GENERIC_WRITE,NULL,NULL,OPEN_EXISTING,FILE_FLAG_OVERLAPPED,NULL
Message>FileHandle

Again it didn't work! It said the dll can't be loaded. How the hell can I get the file's handle?

p.s. I agree ImageMagick is wonderful. XP also has powerful API function for pictures, but quite complicated. If you don't want to rely on the third-party software, use these funtions.

1. The function alias is CreateFileA - there's no such export as CreateFile
2. Have you declared the values for GENERIC_WRITE, NULL, OPEN_EXISTING and FILE_FLAG_OVERLAPPED - these are not Macro Scheduler variables and you don't appear to have given them any values in your script so these are just literal strings and will cause the function to crash.
