why network path (or mapped driver path) is not working?

I have a picturebox object, I want to assign image to that picturebox, the problem that the image is located in my server, I got a driver mapped for images folder (Z: driver), so I was trying:

string imgPath = System.IO.Path.Combine("Z:\\",row.Cells["ImgPath"].Value.ToString());
picturebox.Image = System.Drawing.Image.FromFile(imgPath, true);

// this code is not working, null is returned from Image.FromFile method

Open in new window

but previous code is not working, null is returned from Image.FromFile method.

I tried the UNC path: \\192.168.1.161\d$\ProductManagmentSystem\images\175.png
but also that is not working

so any idea what to do?

I got this exception:
Parameter is not valid.

this is the code:

string imgPath = System.IO.Path.Combine("\\\\192.168.1.161\\ProductManagmentSystem\\", row.Cells["ImgPath"].Value.ToString());

Bitmap b = new Bitmap(imgPath);

the actual value of ImgPath is: "\\192.168.1.20\ProductManagmentSystem\images\175.png"

so what to do?

Bitmap may not accept UNC paths, but Image.FromFile(imgPath, true) will. I did that kind of code before and some links confirm my construct:

Please replace:
picturebox.Image = System.Drawing.Image.FromFile(imgPath, true);
with:
if (File.Exists(imgPath))
picturebox.Image = System.Drawing.Image.FromFile(imgPath, true);
Note: Please post .net , vs version.

I got invalid path,
here is code snippet:

foreach (DataGridViewRow row in dgvProductsGridTMP.Rows)
                {
                    string imgPath = System.IO.Path.Combine("\\\\192.168.1.20\\ProductManagmentSystem\\", row.Cells["ImgPath"].Value.ToString());

                    if (System.IO.Directory.Exists(imgPath))
                    {
                        row.Cells["productImage"].Value = System.Drawing.Image.FromFile(imgPath);
                    }
                    else
                    {
                        MessageBox.Show("Invalid Path");
                    }
                }

Open in new window

its .net 3.5 2008

It is invalid path because you are using Directory.Exists, you have to use File.Exists

ASKER

yes, you are right, buy still I have same problem,

here is image snapshot:

I tried it without File.Exists, I got exception not found:

but its there, I can see it in mapped driver, so there is access to the file!

foreach (DataGridViewRow row in dgvProductsGridTMP.Rows)
{
string imgPathx = System.IO.Path.Combine("\\\\192.168.1.20\\ProductManagmentSystem\\", row.Cells["ImgPath"].Value.ToString());

if (System.IO.File.Exists(imgPathx))
{
row.Cells["productImage"].Value = System.Drawing.Image.FromFile(imgPathx);
}
else
{
MessageBox.Show("Invalid Path");
}
}

//noticed that imgPath from row.cells did not change, but the variable imgPathx change.

systan

if not workin, try to use computer name, not ip address.

If you type in windows explorer:
\\192.168.1.20\ProductManagmentSystem\images\
- Can you see your file? Are you using the same user when you are running your application?
- Is this a desktop(winforms/wpf) or asp.net application or windows service? the solution posted above works for winform applications only. What kind of project does your posted code belong to?
