What's the code? What are the inputs to the "Arithmetic operations"? What are the expected results of the arithmentic operations?

What I am doing is just fire a query from sql server, If the number of records are 30000 then there is no problem but after 32000 records is show an error.I am releasing memory after every 50 page like that
If gstrHTMLFileCounter Mod 50 = 0 Then
GC.Collect()
GC.GetTotalMemory(True)
GC.WaitForPendingFinalizers()
End If
I am not using integer all the fetch records are string ?
Thanks

I would guess that it is actually after 32767
You have an Int16 somewhere in your .NET code or a SMALLINT in your database. However, since you show neither I cannot see what it might be.

But I am not using Int16 in dot net code and SMALLINT in database, still getting error.

Well, something has a signed 16bit limit on it and that is the most likely cause of your overflow error.
You need to post appropriate code - that includes the declaration of variables so the types are known.

Hi colin, I am calling our own API for creating a PDF files at run time. Also I am releasing memory after every 10 pages created at run time like that
If gstrPDFFileCounter Mod 10 = 0 Then
GC.Collect()
GC.GetTotalMemory(True)
GC.WaitForPendingFinalizers()
End If
But after 1046 files created successfully It stops creating pdf files and does not show any error. I think there is some memory leak. How do i fix it.
Thanks

Do you have an int somewhere that you are indexing and maybe not setting back to zero between writes?

This is the ASP.NET forum. You would be better of asking the question in the C# forum instead, as it's not web related.

I am developing an application in which I have to ask the user to upload some file (of .jpg,.gif or .bmp formats). I want to store that file in a directory in my root directory of the application. I need to create a special folder for each user in that folder and paste those files uploaded from the user. Plz send me some sample code if u have any or just send me some suggestion of the classes and functions to be used.
Thanks,
Sandy

// Creating Directory

{
Directory.CreateDirectory(strFolder);
}
//Saving source file to destination
if( ctlImageInput.Value !="")
{
strFileName = ctlImageInput.PostedFile.FileName;

Hi Sathisha,
Did u assign the dataset to the data source property of the crystal report.Check if there are any rows in the table.If the table is empty or if the query results are empty there are chances of getting this error.
