And one like (if (sender.GetType().Name == "Button")) would make it generic and exception-resistant. I am actually trying to see how to avoid the System.InvalidCastException The specified cast is not valid.

Try this:
Button btn = sender as Button;
if (btn != null)
{
}Basically, if you cast an object using Button btn = (Button)sender; you end up with an exception if sender isn't a button (or child of said type). The "as" keyword, attempts the cast and leaves it as null if can't complete the cast - hence the null test. There is a third option, but it's a bit wasteful:
Button btn = null;
if (sender is Button)
btn = (Button)sender;

You may need to use a Windows Service to achieve this.

Hi,
I'm transmitting recorded video file over LAN using UDP but sometimes file transmit successfully and sometimes at receiving side(client) it doesn't receive properly whereas at server side I get transmitting message.
Please See my code and give me suggestion to overcome this problem.
public void filercvold()<br />
{ <br />
<br />
outStream = File.OpenWrite(filepath);<br />
bufOutStream = new BufferedStream(outStream);<br />
<br />
i=0;<br />
while (i<=fsize)
{<br />
try<br />
{<br />
<br />
<br />
idsock.ReceiveFrom(rcvfilebuf, ref idep);<br />
<br />
bufOutStream.Write(rcvfilebuf, 0, rcvfilebuf.Length);<br />
<br />
i++;<br />
<br />
}<br />
catch (SocketException ttt)<br />
{<br />
MessageBox.Show(ttt.Message);<br />
}<br />
<br />
}<br />
<br />
bufOutStream.Flush();<br />
bufOutStream.Close(); <br />
outStream.Close(); <br />
MessageBox.Show("File is completly received!!");<br />
}
//outStream is FileStream Object
//bufOutStream is BufferedStream Object
idsock is socket object
// rcvfilebuf = new byte[16384]; 16KB packet
Now whenever I got last msg "File is completly received" File fully saved and run properly. but when I dont get this msg as at server side I got transmitting msg but at same time at client side above notification doesn't show as client become stuck or remain in this statement " ReceiveFrom(rcvfilebuf, ref idep);"
Now tell me how to check this or rcv full video every time as it doesnt happen everytime.By same code I got this msg and run video file at client but by same code above problem I face so what is main reason or where I'm doing wrong.
Thanx in advance.
Regards,
Shanzay

Without seeing all of the related code, we probably can't help you.

1) Give us the *exact* error message you're seeing.
2) What OS are we talking about?
3) Make sure you're using the correct account to install the service.

Put a try/catch block around the whole thing and look at the exception you're getting. That should give you a hint as to what you need to do to fix it.

Hi,
I have to fix an issue of a windows application. In my app I have to allow user to print report. Application should print record and each page must have 86 lines and each line consist of 134 characters. I have more then 86 records but its printing only 1 record. My code is :
PrintDialog printDialog;
PrintDocument printDocument;
for (int iCtr = 0; iCtr < intPageCount; iCtr++)
{
// this ProcessTransaction_82210() runs a COBOL program which returns formated record which
// contains 86 lines per page and each line contains 134 characters and here I am
// concatinating all the records to a string variable strPrint.
strPrint1 = ProcessTransaction.ProcessTransaction_82210(iCtr);
strPrint += strPrint1;
if (string.IsNullOrEmpty(strPrint.Trim()))
{
break;
}
}
try
{
printDialog.Document = printDocument;
printDocument.PrintPage += new PrintPageEventHandler(onPrintPage);
}
catch (Exception exc)
{
MessageBox.Show(exc.Message.ToString());
}
if (printDialog.ShowDialog() == DialogResult.OK)
{
printDocument.Print();
}
private void onPrintPage(object sender, PrintPageEventArgs e)
{
Graphics g = e.Graphics;
int x = e.MarginBounds.Left - 50;
int y = e.MarginBounds.Top - 50;
System.Drawing.Brush brush = new System.Drawing.SolidBrush(Color.Black);
try
{
g.DrawString(strPrint, new System.Drawing.Font("Courier New", 8, System.Drawing.FontStyle.Regular),brush, x, y);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message.ToString());
}
}
But the application is printing only 1 page. Can any one please let me know how to print same number of pages as in string/document. ProcessTransaction_82210() method also return Page nbr along with records.
we need to set e.HasMorePages = true but how to know it has more pages.
Please let me know the code how to print more nbr of pages. Its very urgent.
Best Regards,
Chandan Kumar

I can't actually see anything in your onPrintPage method about e.HasMorePages = true. Without this, the print will think that it has actually finished.
|
|
|
|
|
I had records which requires 2 pages to be printed , however when I pass e.HasMorePages = true; then it starts printing so many pages. it displays a dialog "printing 140 of document". how can I intimate printer that I have 2 pages to print.
Best Regards,
Chandan Kumar
