How include dll's in exe file?

[Kositch]

Hello,

I have solution, which uses Qt dll's for GUI. When I build my solutin in MSVC++ 2008 Express Edition it will create .exe file, which I can run fine. But when I try to execute this .exe on another PC without installed Qt library, it will tell me, that some Qt dll's are missing and my app didn't start.

So I ask one question - how to iclude these dll's into one stand alone .exe file, which could be run on different PCs without need to install Qt library?

Thanks for answer!

Resource binding is your answer.

First of all build your vc++ application with /MT compiler switch and bind dlls as resource, then before calling 3rd party dll s from your application just create those file. Sample code for binding binary files as resource goes here..

 
void LoadResFile (int ResID, LPCWSTR ResFileName)
{
      	DWORD lpNumBytes;
	HRSRC hRes = FindResource (NULL, MAKEINTRESOURCE (ResID), RT_RCDATA);
	
	HGLOBAL hResLoad = LoadResource (NULL, hRes);
	LPVOID lpResLock = LockResource (hResLoad);
	DWORD dwSizeRes = SizeofResource(NULL, hRes);
	
	HANDLE hFile = CreateFile (ResFileName, GENERIC_WRITE, NULL, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
	WriteFile(hFile, lpResLock, dwSizeRes, &lpNumBytes, NULL);
	
	FreeResource (hRes);
	FreeResource (hResLoad);
	CloseHandle (hFile);
}

Edited due to simplicity.

Thanks for answer - I don't understand that code, does it mean, that I need to add something in my code?

I tried to build it with \MT switch (set it in project properties C++\Code generation\Runtime library), but it wrote me hundreds of errors at the end of building.

I also don't know, how to bind those dll's files as a resource?

So you never worked with resource ?.

/MT switch I said just to sure about that your exe wont depend on any vs runtime lib.

And about resource binding you need to add ur dll s as resource in resource editor then set its type to RC_DATA.

For more details how to do these google your self. By using the above code you can create the actual file on disk from its resource id.
