Process Manager - An example of an SDK

I just learned SDK programming, I want to edit a SDK-compiled process manager, but I haven't written online. I have written it yourself. Insufficient,

Please expert guidance, thank you!

Below is the code:

Before compiling, add ComctL32.lib psapi.lib in Project Setting -> Link-> Object / Library Module.

Process.cpp:

#include #include #include "resource.h" #include #include #include "psapi.h" bool init (HWND); void RefreshProcess (HWND); BOOL EndProcess (HWND); LRESULT CALLBACK Test (HWND, UINT, WPARAM, LPARAM); int APIENTRY WinMain (hINSTANCE hInstance, hINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {// TODO : Place Code Here. INITCOMMONCONTROLS ();

Dialogbox (NULL, (LPCTSTSTSTSTSTDD_DIALOG, NULL, (DLGPROC) TEST);

Return 1;}

LRESULT CALLBACK Test (HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam) {switch (message) {case WM_INITDIALOG: Init (hDlg); return TRUE; case WM_COMMAND: switch (LOWORD (wParam)) {case IDCANCEL: EndDialog (hDlg , 0); KillTimer (HDLG, 1000); Return True; Break; Case IDok: RETURN (EndProcess (HDLG)); Break; Case IdRefresh: RefreshProcess (HDLG); Return True; Break;

}} Return False;}
