WinAPI DLLs Documentation

[7J1L1M]

Hi,

I recently discovered the immense power of the DLLs User.dll, Winmm.dll, Comctl32.dll, and GDI32.dll, all located under system32 in WINNT.    I looked at the functions that they perform and want to use them, but there is very little documentation on their overall funtion and how to set up (in my case) a DLL Interface Node.    Does someone know of webpages or have documentation that would tell me:

Their basic funtion and usage

Configuration settings.

I would greatly appreciate some help!  Thanks.

Try here.  I've found their developer network/help stuff a bit clunky, so be prepared for a bit of digging.  This should be a good start though.

You might also want to take a look at the lvwutil32.zip, available from NI. It contains a bunch of functions using those DLLs.

Just to make this clear...  I'm referring to Microsoft's DN, not NI's.  NI's is pretty good 🙂

Thanks.  What about the cursor, icon, and tranlucency commands in User32.DLL?

Search this forum and the general NI site. Examples exist.

Thanks.

BTW, write now I am trying to find a funtion that writes a cursor/icon after using the "CreateIcon" or "CreateCursor."  This is one of the main reasons I want to use User32.DLL.  In other words, I'm working on "ReadIcon," "ReadCursor," "WriteIcon," and "WriteCursor" commands.  Any suggestions?

Thanks,

Get a book, for example, Charles Petzold's Programming Windows the definitive guide to Win32 API.

Hay again,

I am finally figuring out some of the DLL stuff.  Right now I'm working on a right-click menu that comes from User32.DLL, but I'm having trouble defining one of the datatypes.  Could you help me?  The first link below is a link to the function I'm using, and the second defines the datatype I'm working on.  If you can figure it out, would you send it to me as a ctl file?  Thanks.

Hay again,

I finally found that if you put the correct files into the same directory as the DLL, then the "Call Library Function Node" automatically configures itself.  So what files would I put with say USER32.DLL so when I open it in the Library Function Node, it automatically configures?  Everytime I try to manually do so, I always mess up.  I would greatly appreciate help in this area.

P.S.  I am using LabVIEW 7.1
