Why is GetCurrentDirectory() throwing an exception and how can I fix it?

Error in Getting Current Directory

Problem:
An exception is encountered when attempting to obtain the current directory using GetCurrentDirectory().

Possible Cause:
The LPTSTR variable NPath has not been properly initialized.

Recommended Solution:
To address this issue, allocate memory for NPath before using GetCurrentDirectory(). Alternatively, consider utilizing the GetModuleFileName() function to obtain the executable path.

Code Example for Using GetModuleFileName():

TCHAR buffer[MAX_PATH] = { 0 };
GetModuleFileName( NULL, buffer, MAX_PATH );

Code Example for Extracting Directory from Path:

std::wstring ExePath() {
    TCHAR buffer[MAX_PATH] = { 0 };
    GetModuleFileName( NULL, buffer, MAX_PATH );
    std::wstring::size_type pos = std::wstring(buffer).find_last_of(L"\/");
    return std::wstring(buffer).substr(0, pos);
}

By utilizing GetModuleFileName() and extracting the directory portion, you can successfully obtain the current directory without encountering exceptions.
