Page fails if there is no Image uploaded

[zizi2]

Hi,

I have a webform that uload images as well. The image is uploaded well but the problem arises when the user does not upload any image. I want the form to save nothing for the image_name in the database if there is no image loaded but it does not get to the art of saving to the database, please see my code below and the error I am getting:

if( filMyFile.PostedFile != null )
 {
 
     string strFilename;  
     strFilename = filMyFile.PostedFile.FileName;    
     strFilename = System.IO.Path.GetFileName(strFilename);
     filMyFile.PostedFile.SaveAs(@"C:\Advert_images\"+strFilename);
 }
else
{
 
// No file
 
}

This is the error I am getting when there is no image uploaded:
Exception Details: System.IO.Direc toryNotFoundExc eption: Could not find a part of the path "C:\Advert_imag es\".



Any help will be highly appreaciated.

The exception make me think that your system have no folder with the name Advert_images in partition C.
But what line arise this exception.

Hi Bassem, thanks. It fails on the line 'filMyFile.Post edFile.SaveAs(@ "C:\Advert_imag es\"+strFilenam e', I would have thought it does not have to go inside the if statement if filMyFile.Poste dFile is null, it would simply go to the ELSE part and do nothing?

Sorry for late, my keyboard is damaged and I had to buy a new one.
filMyFile.Poste dFile will not equal null at any way. So check like this:

        if (filMyFile.PostedFile.ContentLength != 0)
        {
            string strFilename;
            strFilename = filMyFile.PostedFile.FileName;
            strFilename = System.IO.Path.GetFileName(strFilename);
            filMyFile.PostedFile.SaveAs(@"C:\Advert_images\" + strFilename);
        }
        else
        {
 
            // No file
 
        }

Now the exception arise because the folder Advert_images doesn't exist. Be sure you already created it.

Regards,

Thanks, it works like a charm when I use if (filMyFile.Post edFile.ContentL ength != 0) . Sorry but I'm new to .Net programming so I need help again. I am trying to display a computer name in a texbox but I am failing, please look at my code below:

string macname = Environment.Mac hineName;
txtECN.Text = macname[0].ToString();

[zizi2]

How do I concatenate two textbox values into one table column, can anyone please help?

[Curtis Rutland]

What kind of table are you talking about?

String concatenation is simple enough:

string s = textbox1.Text + textbox2.Text;

Also, please don't keep posting new questions in your old thread. One topic, one thread. New topic, start a new thread.

@zizi2
Environment.Mac hineName returns a string, but in the next line you get only the first character only macname[0].

It should be like that :

string macname =   Environment.MachineName;
txtECN.Text = macname;
