{

    ZeroMemory(&bi, sizeof(BROWSEINFO));   
    bi.hwndOwner = hWnd; 
    bi.pszDisplayName = path;    
    bi.lpszTitle = TEXT("请选择文件夹");  
    bi.ulFlags = BIF_NEWDIALOGSTYLE | BIF_EDITBOX;  
    LPITEMIDLIST pidl = SHBrowseForFolder(&bi); // 调用浏览文件夹对话框
    if (NULL != pidl) { // "确定"按钮
        SHGetPathFromIDList(pidl, path); // 获取选择的路径      
        MessageBox(hWnd, path, "Tips", MB_OK);

打开文件对话框

GetOpenFileName
The GetOpenFileName function creates an Open dialog box that lets the user specify the drive, directory, and the name of a file or set of files to open.

BOOL OpenFileControl(HWND hWnd, char *path, int size) {
    OPENFILENAME ofn;
    ZeroMemory(path, size);
    ZeroMemory(&ofn, sizeof(OPENFILENAME));
    ofn.lStructSize = sizeof(OPENFILENAME);
    ofn.hwndOwner = hWnd;
    ofn.lpstrFilter = "JPEG type(*.jpg;*.jpeg)\0*.jpg;*.jpeg\0Bitmap type(*.bmp)\0*.bmp\0所有文件(*.*)\0*.*\0\0"; // 默认打开*.jpg格式文件
    ofn.lpstrFile = path; // 存储打开文件路径
    ofn.nMaxFile = size; // 上述路径buf大小
    ofn.lpstrInitialDir = NULL;
    ofn.Flags = OFN_DONTADDTORECENT | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_NONETWORKBUTTON | OFN_PATHMUSTEXIST;
    if (GetOpenFileName(&ofn)) { // "确定"按钮
        MessageBox(hWnd, path, "tips", MB_OK); 
        return TRUE;
    }
    strcpy(path, "");
    return FALSE; // "取消"按钮
}

保存文件对话框

GetSaveFileName
The GetSaveFileName function creates a Save dialog box that lets the user specify the drive, directory, and name of a file to save.

BOOL SaveFileControl(HWND hWnd, char *path, int size) {
    OPENFILENAME ofn;
    ZeroMemory(path, size);
    ZeroMemory(&ofn, sizeof(OPENFILENAME));
    ofn.lStructSize = sizeof(OPENFILENAME);
    ofn.hwndOwner = hWnd;
    ofn.lpstrFilter = "Auth type(*.auth)\0*.auth\0所有文件(*.*)\0*.*\0\0";  
    ofn.lpstrDefExt = "auth";
    ofn.lpstrFile = path;
    ofn.nMaxFile = size;
    ofn.lpstrInitialDir = NULL; 
    ofn.Flags = OFN_DONTADDTORECENT | OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY | OFN_NONETWORKBUTTON | OFN_PATHMUSTEXIST;
    if (GetSaveFileName(&ofn)) {
        MessageBox(hWnd, path, "tips", MB_OK);
        return TRUE;
    }
    strcpy(path, "");
    return FALSE;
