推荐答案

<pre lang="midl">openFileDialog1->ShowDialog();<br />
textBox1->Text = openFileDialog1->FileName;</pre><br />

尽管该示例最有可能运行良好，但它需要.NET和问题关于C ++.
如果您不想使用.NET，则可以使用以下内容:

While that example most likely will work fine, it requires .NET and the question was about C++.
If you wouldn''t want to use .NET, you could use something like this:

BOOL GetFileName(char *filename,int maxlen)
{	OPENFILENAME ofn = {0};

	ofn.lStructSize  = sizeof(ofn);
	ofn.Flags        = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;
	ofn.hInstance    = GetModuleHandle(0);
	ofn.lpstrFile    = filename;
	ofn.nMaxFile     = maxlen;
	ofn.nFilterIndex = 1;
	ofn.lpstrFilter	 = "Any file\0*.*\0\0";
	ofn.lpstrDefExt	 = "*";
	return GetOpenFileName(&ofn);
}

char filename[MAX_PATH];
if(!GetFileName(filename,MAX_PATH))
	MessageBox(0,"Canceled by user."," ",0);
else{
	// Do what you want to do with your file
}

现在从filename中提取路径，例如，您可以使用 PathRemoveFileSpec [ ^ ].
如果您只想获取目录，即如果您对文件名不感兴趣，则也可以使用

Now to extract the path from filename, you could for example use PathRemoveFileSpec[^].
If getting a directory is all you want to do, i.e. if you''re not interested in the name of the file, you could also select a directory right away with SHBrowseForFolder[^].
