Scene description

Locate the breakpoint above HMODULE instance =: LoadLibrary (filename.c_str ()); function, when loading test.dll, find the handle is empty, and then add the following code: DWORD dwError = GetLastError ()

Behind this function, the error code of load failure is collected: [127]-the specified program cannot be found. Click the VS menu, then select tools, click error finding, and enter 127th.

Resolution Analysis:

1) the general situation is that the program runs in the way of dynamic loading. In the process of loading DLL, it is found that the function that the program needs to call can not be found in DLL, thus causing an error.

2) you can see that a method was modified in DLL, but this is not the case when it is called through the header file.
