从SaveDialog中获取FileName并动态更改它c++

#include <windows.h>

int main()
{
    OPENFILENAME ofn;
    TCHAR szFile[MAX_PATH] = { 0 };

    ZeroMemory(&ofn, sizeof(ofn));
    ofn.lStructSize = sizeof(ofn);
    ofn.hwndOwner = NULL;
    ofn.lpstrFilter = TEXT("All Files (*.*)\0*.*\0");
    ofn.lpstrFile = szFile;
    ofn.nMaxFile = sizeof(szFile);
    ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY;
    ofn.lpstrDefExt = TEXT("txt");

    if (GetSaveFileName(&ofn))
    {
        // 获取用户选择的文件名
        TCHAR* fileName = ofn.lpstrFile;

        // 动态更改文件名
        // 这里可以根据需要进行处理，例如添加时间戳或其他标识符
        // ...

        // 打印更改后的文件名
        MessageBox(NULL, fileName, TEXT("New File Name"), MB_OK);
    }

    return 0;
