hi frds, can u solve this doubt in file uploading

hi , thank u for ur reply, i got ur point and i sucessfully completed also i captured size of file when adding and removing file when it exceeds, thank you

take care

regards

ram

Hello,
The code which I send to you is just an example, you need to modify it a bit according to your file size.

See below given lines carefully

 int FileSizeKB = FileSize / 1024;
                    if (FileSizeKB < 200)

In this code we limit user to upload file which is less than 200kb.

So if you need to limit user to 20mb then change it's value to 20480kb

int FileSizeKB = FileSize/1024
if (FileSizeKB < 20480)
{
   // do whatever you want
}
else
{
}

Hope you will got my point

                int FileSize = FileUpload1.PostedFile.ContentLength;
                if (FileUpload1.PostedFile != null && FileSize > 0)
                {
                    int FileSizeKB = FileSize / 1024;
                    if (FileSizeKB < 200)
                    {
                        //do whatever you want


                        string fn = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
                        string SaveLocation = Server.MapPath("Data") + "\\" + fn;
                        try
                        {
                            FileUpload1.PostedFile.SaveAs(SaveLocation);
                            Response.Write("The file has been uploaded.");
                        }
                        catch (Exception ex)
                        {
                            Response.Write("error occured");

                        }
                    }
                }

            }

if (ControlName.Value != "")
{
    int FileSize = ControlName.PostedFile.ContentLength;
    if (ControlName.PostedFile != null && FileSize > 0)
    {
        int FileSizeKB = FileSize / 1024;
        if(FileSizeKB < 200)
        {
            //do whatever you want
         }
         Else
         {
             "show your error message";
         }

Positively this will solve your problem just take file size value from your web.config file as you mention that you want to access file size from web.config
