ASP. NET (use c #). The file storage dialog box is displayed.

After you click Download to download an mp3 file, it will be played by Media Player and cannot be saved. it is inconvenient. After searching online for a long time, you can finally find a solution and post it to you.

 

Try
...{
Fullfilename = server. mappath (filename); // filename -- name of the file to be downloaded
Fileinfo downloadfile = new fileinfo (fullfilename );
If (downloadfile. exists)
...{
Response. Clear ();
Response. clearheaders ();
Response. Buffer = false;
Response. contenttype = "application/octet-stream ";
Response. appendheader ("content-disposition", "attachment; filename ="
+ Httputility. urlencode (downloadfile. fullname, system. Text. encoding. ASCII ));

Response. appendheader ("Content-Length", downloadfile. length. tostring ());
Response. WriteFile (DownloadFile. FullName );
Response. Flush ();

Response. End ();
}
Else
...{
// The file does not exist.
}
}
Catch
...{
// The file does not exist.
}

 

 

In addition, the answer to net_lover (Chapter E of Mencius) can only save the current URL file name. The following is the code. A dialog box with colors is displayed.

Onclick = "document.exe cCommand ('shanghaias ')"
<Input onclick = "a ()">
<Script>

SInitColor = null
Function ()
...{
If (sInitColor = null)
Var sColor = document. all. dlgHelper. ChooseColorDlg ();
Else
VaR scolor = Document. All. dlghelper. choosecolordlg (sinitcolor );
Scolor = scolor. tostring (16 );
If (scolor. length <6 )...{
VaR stempstring = "000000". substring (-scolor. Length );
Scolor = stempstring. Concat (scolor );
}
Scolor = "#" + scolor
Alert (sColor)
}

</Script>
<OBJECT id = dlgHelper CLASSID = "clsid: 3050f819-98b5-11cf-bb82-00aa00bdce0b" width = "0px" height = "0px"> </OBJECT>
