如何获取资源文件中的数据？

Question

I get the NULL(hRsrc) when it is running.

.cpp

HINSTANCE hInstance = AfxGetInstanceHandle();

HRSRC hRsrc = FindResource(hInstance, MAKEINTRESOURCE(IDR_EXE1), _T("EXE"));

if (hRsrc == NULL) {
    MessageBox(NULL, TEXT("LoadEmbedded"), TEXT("1"), MB_OK);
}

HANDLE hRes = LoadResource(hInstance, hRsrc);
if (hRes == NULL) {
    MessageBox(NULL, TEXT("LoadEmbedded"), TEXT("2"), MB_OK);
}

LPSTR lpRes = (LPSTR)LockResource(hRes);
if (lpRes == NULL) {
    MessageBox(NULL, TEXT("LoadEmbedded"), TEXT("3"), MB_OK);
}

.rc

IDR_EXE1                EXE                     "crashpad_handler.exe"

I set the data id and type.

resource.h

#define IDR_EXE1                        105

Answer 1

Does the .rc file have an #include "resource.h" statement?

If not, then the IDR_EXE1 macro won't be defined when the .rc is compiled, and thus the resource's ID will be the literal string "IDR_EXE1" and not the numeric 105 (use a resource viewer tool to verify that). In which case, you would have to use _T("IDR_EXE1") instead of MAKEINTRESOURCE(IDR_EXE1) when calling FindResource() :

HRSRC hRsrc = FindResource(hInstance, _T("IDR_EXE1"), _T("EXE"));

Otherwise, fix the .rc file:

#include "resource.h" // <-- add this!

IDR_EXE1                EXE                     "crashpad_handler.exe"
