VC++ 获取当前模块的路径(dll/exe)

一般地，获取当前模块路径都是通过调用 GetModuleFileName() 来获取的。

参数

hModule

A handle to the loaded module whose path is being requested. If this parameter is NULL, GetModuleFileName retrieves the path of the executable file of the current process.

lpFilename

A pointer to a buffer that receives the fully-qualified path of the module. If the length of the path exceeds the size that the nSize parameter specifies, the function succeeds, and the string is truncated to nSize characters and cannot be null terminated.

The string returned will use the same format that was specified when the module was loaded. Therefore, the path can be a long or short file name, and can use the prefix "\\?\". For more information, see Naming a File.

nSize

The size of the lpFilename buffer, in TCHARs.

方法一： 适用于获取dll、exe路径，可在console、MFC、ATL工程中使用。

char szBuff[MAX_PATH] = {};
HMODULE hModuleInst = _AtlBaseModule.GetModuleInstance();
GetModuleFileName(hModuleInst, szBuff, MAX_PATH);

方法二：适用于获取dll、exe路径，可在MFC、ATL工程中使用，不能再console中使用。

char szBuff[MAX_PATH] = {};
GetModuleFileName(AfxGetStaticModuleState()->m_hCurrentInstanceHandle, szBuff, MAX_PATH);

方法三：适用于获取dll、exe路径，可在MFC、ATL工程中使用，不能再console中使用。

char szFull[_MAX_PATH] = {};
GetModuleFileName((HMODULE)&__ImageBase, szFull, _MAX_PATH);
