Ringtone file name is not saved on my mobile handset

Hello,

I have created a Mobile Application in C# .net.
I am sending a WAPPush SMS for users who may request Mobile Services such as (Ringtones, Pictures).
I have a problem in downloading ringtone(True Tone of file extension AMR) on WAP Browser, the ringtone name is not saved. After downloading the Ringtone file
takes the link file name "userlink" which appears in url(ex, url: http://IP/webapplication?userlink.aspx?pwd=887768).The file name (amr) is not known on WAP Browser, so I am sending the link to users to download it .The idea is I can download file type AMR (or in MP3...) from my Web Browser but it is not saved on mobile handset in its real name just it can be heard. Also I am giving the file name through this syntax: Response.AppendHeader("Content-Disposition",

"attachment;filename="+ szFileName.Trim());
The code is Below:
Please help to fix my problem as soon as possible

...........

//*********************************************

private void Download(int szID)
{
string szContent="";
string szType="";
string szFileName="";
SqlConnection Conn = new SqlConnection(objGeneral.GetConnect());
string sqlselect="SELECT ContentUrl,Type,ContentName FROM ContentType where ID='"+szID+"' ";
Conn.Open();
SqlCommand CmdObj = new SqlCommand(sqlselect, Conn);

SqlDataReader ReaderObj = CmdObj.ExecuteReader();

if(ReaderObj.Read())
{

Response.Clear();

szContent=ReaderObj.GetString(0);
szType=ReaderObj.GetString(1);
szFileName=ReaderObj.GetString(2);
FileInfo f = new FileInfo("C:\\Inetpub\\wwwroot\\MobileServices\\"+szContent);
Response.Clear();
Response.AppendHeader("Content-Disposition:inline", "attachment;filename="+ f.Name);
Response.AddHeader("Content-Length", f.Length.ToString());
//Response.ContentType=szType ;
Response.ContentType="text/vnd.wap.wml";
Response.AddHeader("pragma","no-cache");

if(!ReaderObj.IsDBNull(2))
{

Response.WriteFile(f.FullName);
Response.End();

}
else
{
Response.Write("no image exists!!");
}
ReaderObj.Close();
}

}

Regards,
Ranine

Hi Ranine,

Welcome to Dev Shed.

I don't really know c# at all, but shouldn't the content type be set to match the type of the file you are trying to download. (eg: audio/mpeg for mp3)

You have it as

Code:

Original - Code
Response.ContentType="text/vnd.wap.wml";

Response.ContentType="text/vnd.wap.wml";

Good list here if you are needing more info on mime types ....

hi Jabba:

Yes that's right the content type should match the file type which is retrieved from Database. But as I told you the Ringtone file wasn't saved on my mobile after downloading.
Here in the code above I was trying to change the Response.ContentType="text/vnd.wap.wml";
it has given me this error:
//*************************
HTTP Error : 400 (Bad Request)
<html><body>Bad Request</body></html>
//*********************************

I think that maybe the main reason for such error as the source code userlinks.aspx.
Please Jabba in your opinion do I have to change the C# code into WML? if So can you help me....

Regards,
Ranine

Is userlink.aspx the page that the snippet of code is taken from?

The file is actually in a database - is it stored in the correct format there?
Have you tried the same code but made it available to a web browser so that you can test that it works and that the format is correct?

Your uri has "?pwd=887768" where presumably pwd relates to ID='"+szID+"' in your query - is your query successful - you don't seem to show any error trapping *.

* That may just be my lack of knowledge in c# though

The userlink.aspx is the snippet of Code which is taken from.
I have traced my code more than 100 times

, and all what are retrieved from Database are correct like :Content name, Content length (appending the specific headers) , the correct file path..... I am in need for help

!
The ringtone is saved as userlink.mp3 so it takes the file extension and it is heard properly but what about the file real name????
I can accept converting my code into WML wireless markup language maybe it will work

!

Ranine

string strFileName = Name + "." + Format;

//THIS CODE IS WRITTEN TO INCREMENT THE NO OF COUNT IN THE DATABASE
//IncrementFileDownloadCount(RingtoneID);
//CODE END
string originalFilename = strFileName;
string localfilename = Server.MapPath("~/RingtoneFiles") + "/" + strFileName;
WebClient req = new WebClient();
CredentialCache mycache = new CredentialCache();
mycache.Add(new Uri(localfilename), "Basic", new NetworkCredential("administrator", "admin$123"));
req.Credentials = mycache;
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ClearContent();
response.ClearHeaders();
response.Buffer = true;
response.AddHeader("Content-Disposition", "attachment;filename=\"" + originalFilename + "\"");
Response.AddHeader("Content-Type", "audio/mpeg");
