What about CRC? I think that produces a smaller result.

How do you find anything else you're looking for? You search for it. That's what the "search comments" function is for. What did you think it would do?

Hi to All,
I am trying to handle excel file in my application. Here I am trying to get a cell value in the text box on the event of button click. but whenever i run it shows exception that Access is denied..... my code is as follows....
private Excel.Application oXL=null;
private void Button1_Click(object sender, System.EventArgs e)
{
InitializeComponent();
oXL = new Excel.ApplicationClass();
oXL.Visible = true;
Excel.Workbook oWB = oXL.Workbooks.Open("D:\\Pravin\\October-07\\xls\\7starcare-October.xls",0,true,5,"","",true,Excel.XlPlatform.xlWindows,"\t",false, false, 0, true);
Excel.Sheets oSheet= oWB.Worksheets;
Excel.Worksheet oWS = (Excel.Worksheet)oSheet.get_Item(1);
TextBox1.Text= Convert.ToString(oWS.Cells.get_Item(1,1));
}
But whenever i run my application it shows exception as follws ....
------------------------------------------------------------------------------------------------
Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true">, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
----------------------------------------------------------------------------------------------------
how can i remove this problem?

You need to grant the ASPNET machine account, which your site is running under in IIS, read permissions to the file. You can do this in Windows Explorer by right-clicking on the file and selecting the 'Security' tab.

Hey there,
I am new to this language and have been looking at the example program at the link below:
http://www.codeproject.com/dotnet/twaindotnet.asp
but what i wanted was when the image is returned from the scanner, is to convert it to a Bitmap. I have tried numerous ways to convert the ImgPtr but get an ExternalException at runtime. The example seems to use another class to save and display the image, but I would prefer to handle a Bitmap.
Any help would be greatly appreciated
Thanks
Pete

You're probaqbly getting back a HBITMAP, there is a Bitmap.FromHAndle or Bitmap.FromHBITMAP, isn't there ?

Hey all,
Actually i should say that i have a Decrypting problem  !
I am trying to use a certificate to prove the client/server identity in my application. I was sending a welcome message from the server to the client, encryption/decryption worked smoothly, but this message is just a string like the client number, name of the computer where the server is running and all that...
Now when i am doing this:
Publisher publisher = new Publisher(new Init().Certificate());
byte[] message = Encoding.ASCII.GetBytes(new Encrypting().Encrypt(new Init().GetRawCertData(), password));
....
and sending it over the "Network", i am getting a bad data exception... something about a wrong character in the Base64 String.
I am sending fixed length bytes[] and when i am just sending strings it works. But when i try to change the type of data to send it messes up.
My logic to Encrypt/Decrypt is create an instance of the algorithm to use, i use the login password to encrypt/decrypt and i init the key and IV of the algorithm with them, a memory stream and the crypto stream... and return an array of bytes.
Maybe i am doing something wrong, any idea of how to use the certificate better, I am extremely new to Certificates and Digital Signatures. I tried SSL Stream but i could not make work .
Thanks in advance !
Best regards!!!

HI guys,
I have resize picturebox (say picMain) to the size of form.There are many picturebox inside picMain. Now I am moving child
picturebox ( on mouse_move event) on picMain. I am getting refresh problem while dragging child picturebox.
I had use Invalidate(),Update() and Refresh() method of current movable child picturebox but not getting precise solution. It seems like child picturebox ghost is following it. Child picturebox takes more times to refresh.
Instead of picMain if I work with main form then it work very well. I think picturebox has less ability to refresh faster compare
to form (am I write??).
I want same effect as what we dragged item from visual studio toolbox and move around in the form.(its so smooth)
pls give the solution
thanks in advance.

How would I tell if a textbox's text is a number or string? Thanks.

TextBox.Text is always a string; you can get its numeric value if YourNumericType.TryParse()
returns true.
