How to create Save As dialog box in vc++(MFC)?

推荐答案

您可以使用类似这样的内容；

You could use something like this;

int GetFileName(HWND hwndOwner,char *filename)
{	OPENFILENAME ofn = {0};

	ofn.lStructSize  = sizeof(ofn);
	ofn.Flags        = OFN_EXPLORER | OFN_PATHMUSTEXIST;
	ofn.hInstance    = GetModuleHandle(0);
	ofn.hwndOwner    = hwndOwner;
	ofn.nMaxFile     = MAX_PATH;
	ofn.lpstrFile    = filename;
	ofn.nFilterIndex = 1;
	ofn.lpstrFilter	 = "Text file\0*.txt\0Any file\0*.*\0";
	ofn.lpstrDefExt	 = "txt";
	return GetSaveFileName(&ofn);
}

hwndOwner是拥有SaveAs对话框的窗口的句柄，而filename是长度为MAX_PATH的字符数组. 将lpstrFilter和lpstrDefExt变量更改为适合您的应用程序的文件类型.

hwndOwner is a handle to the window that owns the SaveAs dialog and filename is a character array with length MAX_PATH.
Change the lpstrFilter and lpstrDefExt variables to an appropriate file type for your application.

Thaddeus Jones答案是正确的.您还可以使用CFileDialog类:

保存:

Thaddeus Jones answer is correct. You can also use the CFileDialog class:

For saving:

CFileDialog dlg(FALSE, defaultExtension, NULL, OFN_OVERWRITEPROMPT, "All files|*.*||");
if (dlg.DoModal() != IDOK)
{
    //the user didn''t click OK
    return;
}
CString theFileName = dlg.GetPathName();
//save the file...

加载:

For loading:

CFileDialog dlg(TRUE, defaultExtension, NULL, OFN_HIDEREADONLY, "All files|*.*||");
if (dlg.DoModal() != IDOK)
{
    //the user didn''t click OK
    return;
}
CString theFileName = dlg.GetPathName();
//load the file...
