VC++-获得exe(dll)程序所在目录GetSelfModuleHandle

• 版本

vs2012

• 步骤

手动创建一个ini文件

config.ini

将文件另存为ANSI编码格式,用UTF-8编码,读写中文会出现乱码.

• 源代码

#include <string>
#include <afx.h>

using namespace std;


string A1;
string A2;
string A3;


HMODULE GetSelfModuleHandle()
{

    MEMORY_BASIC_INFORMATION mbi;
    return ((::VirtualQuery(GetSelfModuleHandle, &mbi, sizeof(mbi)) != 0)
        ? (HMODULE)mbi.AllocationBase : NULL);
}
CString GetProgramDir()  
{    
    char exeFullPath[MAX_PATH]; // Full path
    string strPath = "";
    GetModuleFileName(GetSelfModuleHandle(),exeFullPath,MAX_PATH);
    strPath=(string)exeFullPath;    // Get full path of the file
    int pos = strPath.find_last_of('\', strPath.length());
    CString path;
    path=strPath.substr(0, pos).c_str();
    return path;
}


void ini_value()
{
    CString        szMainKey, StrIniFile;
    char        szVal[MAX_PATH];
    BOOL        Ret;

    CString DLL_path=GetProgramDir();
    StrIniFile=DLL_path+"\config.ini";

    szMainKey.Format(_T("CONFIG"));
    Ret = GetPrivateProfileString(szMainKey, _T("A1"), _T(""), szVal, MAX_PATH, StrIniFile);
    A1 = szVal;

    Ret = GetPrivateProfileString(szMainKey, _T("A2"), _T(""), szVal, MAX_PATH, StrIniFile);
    A2 = szVal;

    Ret = GetPrivateProfileString(szMainKey, _T("A3"), _T(""), szVal, MAX_PATH, StrIniFile);
    A3 = szVal;

}



void CMFCApplication1Dlg::OnBnClickedButton1()
{
    // TODO: 在此添加控件通知处理程序代码

    //获取当前程序所在目录
    CString exe_path = GetProgramDir();
    AfxMessageBox(exe_path);

    //读取ini
    ini_value();
    
    //打印
    char msg[256];
    sprintf_s(msg, "%s,%s,%s", A1.c_str(), A2.c_str(), A3.c_str());
    AfxMessageBox(msg);
}
