Hi
Might be worth looking in to the Range.set_value method. I've used the get_value method to import a whole sheet in to an array so you should be able to do the reverse easily enough. There is an example here http://stackoverflow.com/questions/2314393/how-to-specify-format-for-individual-cells-with-excel-range-set-value[^]

Why can't you use Response.write with Inline or attachment file type to export data from Grid to Excel.

Hi

I have string say "Deepak"
how do i convert this into a byte array of 44,65,65,70,61,6b. I converted the ascii to
hex-string "44656570616b" using

String.Format("{0:x2}", (uint)System.Convert.ToUInt32(tmp.ToString()));

thanks

Turning a string into its ASCII bytes, if possible, is done using Encoding.ASCII.GetBytes(string)

BTW: The code you have shown converts a number to a string, which in .NET is always using Unicode, not ASCII.

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

i need to get 44,65,65,70,61,6b

GetBytes() returns bytes, which means numbers. You can turn those into strings again using whatever convention you choose. "Deepak" starts with a "D" which is 68 when counting in decimal, 44 in hex, 102 in octal, etc. If you want hex, you probably need to apply ToString("X2") to each of those bytes.

problem in debugging the windows application

hi all,

I have made simple windows based application to illustrate the event fire when we click on the stop debugging button in VS 2008.
Actually, When i click on the "close" button of the form in the running application . It invokes the method as mentioned in the "form_load" event
e.g.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Label1.Text = "Hello"
AddHandler System.Windows.Forms.Application.ApplicationExit, AddressOf abcMethod
End Sub

Private Sub abcMethod()

End Sub

but when i directly click on the "stop" debugging in the menu option in VS 2008,it doesn't go to the breakpoint inserted at the form_load event. I want to know which event fires at click of the stop debugging button in the menu option in vs 2008.
Thank you

AFAIK none. Stopping an app inside the debugger is like killing it in Task Manager, no more code gets executed.

If you click 'Stop Debugging' the program will close, I think immediatly, with no events fired.

If you want to have the ApplicationExit event fire, you need to close your application with the 'X' button or by some method that calls Application.Exit().

Hi,
I have a webservice that send bulk SMS and it works for English language. The problem is when users send SMS using ARABIC text no SMS is receieved.

Please help me to improve or change my code so it will work for arabic characters. I think the problem is when converting the string to UTF-8 code.

MY Webservice:

http://10.45.98.198:8080/Script/SMSArabicEnglish.jws?wsdl

MY C# Code that send the message to my webservice.

string sMessage = وقت البلاغ:" ;
byte[] utfCodes = System.Text.Encoding.UTF8.GetBytes(sMessage);

//second solution

SendGSM.send_sms(utfCodes);

Why don't you just pass the string to web-service rather than passing byte array?

    writer.WriteNode(reader, true);
}

I generally don't think it's such a great idea to let these companies share a single xml file (why not use a database instead?) but to answer your question: Try using a web service to send and receive the file.

Dialog Box

Hi guys, I've tried to add a prompt to display a dialog box when the user pressed a button, it seems an error surfaced when I run the program. The error showed, "no overload for method "Show" takes '3' arguments." May I know what went wrong, any help would be appreciated. Thanks in advance =) Here is the code snippet below.

if (MessageBox.Show("Are you sure?","Save data", MessageBoxButtons.YesNo) == DialogResult.Yes)
   {
      //Do tasks
   }

Hi Rahul, thanks for replying, does it look something like this when I added the fourth argument? I've tried it, but the error still surfaced and this time it shows, "No overload for method 'Show' takes '4' arguments.

if (MessageBox.Show("Are you sure?", "Confirm save?", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
     {
          //Do tasks

                }

If you need to check something like this again, place the cursor after the open brace of the method, and use CTRL+space - this makes IntelliSense show you the various possible overloads for any documented method, including your own. Use Cursor Up and Down to scroll between them.

First of all i want to tell you that in Web form there is no option for message box its available in window form but if you still want to use message box then write this code:

using system.window.form.*;

and perform this change

if (System.WindowForms.MessageBox.Show("Are you sure?","Save data", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
//Do tasks
}

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
