this is my first post on this board... I'm quite new on WinAPI and I have some questions.
1. How can I run another .exe file from my program WITHOUT the system() func? This creates an ugly console win. I wanna run the prog directly.
2. How can I use a bitmap with transparent areas (ya know, these #ffff00
ones) WITHOUT MS Visual C(++)??? All the examples I've seen are using the CreateRgnFromFile() func which isn't part of the standart windows funcs ;-(
Uhm. Forgot some. Nevermind, I'd be awfully happy if any of you could help me with this stuff (mainly the first one). Thxalot!!!
Use CreateProcess() func.:
LPCTSTR lpApplicationName, // name of executable module
LPTSTR lpCommandLine, // command line string
BOOL bInheritHandles, // handle inheritance flag
DWORD dwCreationFlags, // creation flags
LPVOID lpEnvironment, // new environment block
LPCTSTR lpCurrentDirectory, // current directory name
In the MSDN SDK, you can find the detailed explanation of the parameters.
Also, there's an obsolete function, but provided for compatibiliti reasons, and simpler. (but, in fact it calls this same function above)
LPCSTR lpCmdLine, // address of command line
UINT uCmdShow // window style for new application

What do you mean by that? without C++? If you are programming in VC++, than you must use VC++...
If you mean without external functions, than just lookup the filestructure of the BMP files /really easy/, load the file to memory, than display only the pixels you need. for example, you have a bitmap already loaded, than mix this transparent one with that in memory, and when ready, display it. /because if you do the mixing on-screen, it will be viewable, because GDI isn't the fastest thing in the world/ (unless you have a P6-3.5GHz)
If you are using directX, than simply determine the transparent color value, and set the mask registers.
Also, if you want it fast, but no directX thanks, use assembly for the mixing.
No more ideas....
