Quick Question here:
Regarding TransparentBlt(), what do I need to do to use this function?
I have windows.h included, and I have my projected linked to Msimg32.lib just like msdn says and I still can't use it.
The msdn page for this function is here
Is the answer right in front of my face? This has me completely stumped.

You've linked to AlphaBlend and not TransparentBlt.
>>and I still can't use it<<
Please include any error messages as this is meaningless.
>>Is the answer right in front of my face?<<
It will be when you open up the header file in which TransparentBlt is declared and locate that function within it.
If that seems too cryptic then a board search should offer some clarification - I'm fairly certain this question has been asked and answered before.

`TransparentBlt' undeclared (first use this function)Originally Posted by Ken Fitlike
Maybe I'm stupid but I don't see how finding where the function is declared would help, MSDN says to include windows.h and I did.
Well, since you're not going to look at either the file or search the board for yourself.
(more or less).
Board search: TransparentBlt error.

I saw that in the file! I didn't know what it meant, sorryWell, since you're not going to look at either the file or search the board for yourself.

I didn't search the board though sorry again
>>I didn't know what it meant<<
Fair enough.
You need to #define WINVER 0x0500 before you #include <windows.h>, otherwise when your program is compiled the function is not declared - hence the error message you got. It's actually better to set it in whatever preprocessor setting your compiler has (check its documentation) but for smaller projects (one or so files) you can get away without doing so.
I think this is mentioned in the search link I provided, together with a link to further preprocessor definitions that are important when programming for windows which you may find of interest.

Yup, it works now. Thanks for putting up with my stupidity.>>I didn't know what it meant<<
