[RESOLVED] opening Jpg or any picture file in windows photo viewer from within my app

[bayat2000]

Hi All
I am developing an app that can list a lot of folders in my hard drive (each folder contains a picture file) and I want my app can open the picture in folders by windows photo viewer when I click the folder name in combobox.
I tried the code below ,but this just open the windows explore with picture file in it that it is not focused.

Private Sub C_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles C.KeyPress

        Select Case e.KeyChar
            Case Chr(Keys.Enter)
                Process.Start("j:\bimaran\" & C.SelectedItem)
        End Select
    End Sub

that is a dead end for me so any help appreciated.
thanks
bayat

thanks for reply but that was not thing I was asking for.

Think this through. You say your ComboBox contains folder names. So C.SelectedItem will return a folder name. So

"j:\bimaran\" & C.SelectedItem

will contain a path to a folder, such as "j:\bimaran\OneOfYourFolderNames"

You are then passing that path to Process.Start. The result you describe of Windows Explorer opening that folder is exactly what I would expect to happen. You aren't referencing Windows Photo Viewer, or an image file name.

Now, the links jdc2000 posted are absolutely relevant to your question. The fact that you dismissed them is troubling, since it suggests that you might not have fully thought through the specifics of what you are trying to accomplish (hint: Step 1 is to write code that will simply open Windows Photo Viewer. Step 2 is to modify that code to pass the full path, including filename, of the image that you want opened in Windows Photo Viewer) In any event, I'm unable to assist further with this, so good luck.

Dim strCommand As String

strCommand = "rundll32" & Chr$(34) & "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll " & Chr$(34) & Chr$(34) & "j:\bimaran\" & C.SelectedItem & Chr$(34)

Process.Start(strCommand)

Dim strCommand As String

strCommand = "rundll32" & Chr$(34) & "C:\Program Files\Windows Photo Viewer\PhotoViewer.dll " & Chr$(34) & Chr$(34) & "j:\bimaran\" & C.SelectedItem & Chr$(34)

Process.Start(strCommand)

thank you for your code , each folder has a picture file with a different name , can I use ? or * to address each picture file I want to open with rundll32 or not. how?

You would need to get the full file name to open it. This can be done using the Dir statement. See the link below for an idea on how to use it.

Thanks again

Surely there is a more .Net-ish way to do that instead of using Dir

Which one do you mean?
