问题 I am trying to understand how self-extracting PE files work. Can somebody explain why my code isn't working, or fix the main() part. #include <iostream> #include <Windows.h> using namespace std; void ExtractResource(const HINSTANCE hInstance, WORD resourceID, const char* outputFilename); int main() { HINSTANCE hInst = GetModuleHandle (0); ExtractResource(hInst, 101, "101.dll"); ExtractResource(hInst, 102, "102.dll"); ExtractResource(hInst, 103, "103.dll"); ExtractResource(hInst, 104, "104.dll

问题 The following snippet is meant to display the message when the user types a key. Even when the focus is not on the application. But there seems to be a problem with the following code. It doesn't call the function registered in the hook-chain with the windows. I guess the problem is with HINSTANCE hInst . How should I modify the below code so that I am able to see the message as the user taps a key. // Global Variables static HHOOK handleKeyboardHook = NULL; HINSTANCE hInst = NULL; void

Forward declare HINSTANCE and friends

问题 Is there a way to forward-declare the HINSTANCE type from the WinAPI without including the full (and big) windows.h header? For example, if I have a class RenderWindow which owns an HINSTANCE mInstance , i will have to include windows.h in RenderWindow.h . So everything that needs RenderWindow also has to include windows.h . I tried including windef.h but this seems to need some things from windows.h . :-( If I can't forward declare it, is there at least a portable way to use something like

问题 The HINSTANCE of a win32 application is passed to WinMain, but is there any other way of determining the current HINSTANCE (in case you couldn't tell, I'm very new to win32 programming!)? I need to create a window inside of a library and (since the library is cross platform), id prefer not to have to pass it in. 回答1: If memory serves, GetModuleHandle(NULL); returns the instance handle. 回答2: __ImageBase is your friend, especially in the case of libraries. Note that the linked blog post (by R.
