"Not working" is not descriptive. This is not even a question.

Do you think more code makes the post a question? :-)

Elaborate! It's a simple update query... what is the issue that you face?

sakshi1111 14-Sep-12 2:39am

image not be updated....
i got the error on this line like...
if (Convert .ToByte (FileUpload2.PostedFile.ContentLength )> 0)
error--Object reference not set to an instance of an object..

CoderVivs 14-Sep-12 2:36am

Have you copy the exact code ?
You are splitting the file name with ',' you must use '.'

The error implies that your FileUpload Control is not loaded.
It might have design some problem in your design. Just tell me that are you keeping the file upload control and the corresponding button in diffrent updatepanels.

if (FileUpload2.HasFile)
{
int length = FileUpload2.PostedFile.ContentLength;
byte[] imgbyte = new byte[length];
if (length> 0)
{
//int imgsize = FileUpload2.PostedFile.ContentLength;

int imagesize = length / 1024;
if (imagesize< 50)

C#

{
string fn = System.IO.Path.GetFileName(FileUpload2.PostedFile.FileName);
string[] fname1 = fn.Split(',');
int i = fname1.Length;
string fext = fname1[i - 1];
if (fext == "jpg")
{
string serverpath = Server.MapPath("./employeephoto/");
string filelocation = serverpath + "\\" + f[0] + "."+ fext;
//string filelocation = serverpath +"\\" + f[0] + ";."+ fext; /** Path at server to save file**/
//string path = "./photo" + "\\"+ fn; /** Path to enter in database **/
FileUpload2.PostedFile.SaveAs(filelocation);
/*Code to insert values into the table of spareparts*/



Label2.Text = "The Image has been uploaded successfully";
}
  lblerror.Text = "Record updated successfully"

2 things:
1. Make sure you have uploaded a new file for upload. If you think, older one path file still exists, you are mistaken. So, if user has uploaded a new file, you will have access to it for upload.
2. Make sure you check for 'HasFile' property in fileupload control. Checking for file and NULL values are helpful.

Once you have the file, it would be simple update statement. If the file is not browsed and uploaded by user, you wont be able to update it.

Solution 2

C#

if (FileUpload2.HasFile)
            {
                if (FileUpload2.FileName.Split(new char[] { '.' })[1].ToLower() == "jpg")
                {
                    FileUpload2.PostedFile.SaveAs(Server.MapPath(" ") + "\\employeephoto\\" + FileUpload2.FileName);
                }
            }

Thanks 4 Reply.........
But its not working........

CoderVivs 14-Sep-12 3:55am

In your code why you are converting it to byte if you want to upload the image to a directory, use FileUpload2.PostedFile.SaveAs(Server.MapPath(" ") + "\\employeephoto\\" + FileUpload2.FileName);

and see the design are you using updatepanels ?
