Thread: Using resources

Hi, I had no idea if I should post it in Windows Programming or General C-programming, but since win32 is the platform I'm working on I'm posting here...
Mod may move if it's in the wrong section.

So here is my question - I have a program that uses cURL to speak HTTP easily with my webserver.
But cURL needs a couple of DLL-files that should exist in the system32-folder. Now I don't want to ship these files with my executable - but instead have them as resources in my executable and automatically extract them and install in system32.

I am using Dev-Cpp and programming in C.

Do you have any idea on how to implement this in my program?

Thank you for your consideration

I didn't mention error handling etc - but it will offcorse be included.

I have made my choice of handling this problem, and I want to extract them from resources in my executable. With hours of googling, I have yet not found any information.

Btw. This is how I solved it:

resources.rc -

Code:

1 BIN DISCARDABLE "path-to-.dll"

extract.c -

Code:

void Extract(WORD wResId , char szFilePath[])
{
	HRSRC hrsrc;
	HGLOBAL hLoaded;
	LPVOID lpLock;
	DWORD dwSize;
	HANDLE hFile;
	DWORD dwByteWritten;
	
	hrsrc = FindResource(NULL, MAKEINTRESOURCE(wResId) ,"BIN");
	if(hrsrc == NULL)
	{
		//printf("Error Finding resource\n");
	}

	hLoaded = LoadResource(NULL, hrsrc);
	if(hLoaded == NULL)
	{
		//printf("Error Loading Resource\n");
	}
	
	lpLock = LockResource(hLoaded);
	if(lpLock == NULL)
	{
		//printf("Error Locking Resource\n");
	}
	
	dwSize = SizeofResource(NULL, hrsrc);
	
	hFile = CreateFile(szFilePath, GENERIC_WRITE, 0, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_HIDDEN, NULL);
	
	if(!WriteFile(hFile, lpLock , dwSize , &dwByteWritten , NULL))
	{
		//printf("Error Writing to file\n");
	}
	CloseHandle(hFile);
	FreeResource(hLoaded);
}
