Question

I have loaded the files to combo box…

private void Form1_Load(object sender, EventArgs e)
        {
            Directory.CreateDirectory(@"X:\BookStoreProject\WindowsFormsApplication2\Resources\PDF_Books");

            DirectoryInfo dir = new DirectoryInfo(@"X:\BookStoreProject\WindowsFormsApplication2\Resources\PDF_Books");
            FileInfo[] files = dir.GetFiles("*.pdf");
            foreach (FileInfo file in files)
            { 
                cboPDF.Items.Add(file);
            }

I now want to select the pdf from the combo box and load the pdf. But for some reason everything I try is not working. I can run a command (note this a different project)…

System.Diagnostics.Process.Start(@"C:\Users\Shane\Documents\Visual Studio 2010\Projects\Beginning Hibernate, 2006.pdf");

That is giving a direct string path, but my problem is maybe trying to recreate a path like this is the wrong direction?

Answer 1

Process.Start("Path_OF_Pdf.Exe", System.IO.Path.Combine("@X:\BookStoreProject\WindowsFormsApplication2\Resources\PDF_Books",cboPDF.SelectedItem.ToString()));

You need to specify installation path of your PDF as your first parameter and name of pdf file as second.

EDIT from Shane’s Comments

string w = System.IO.Path.Combine(@"X:\BookStoreProject\WindowsFormsApplication2\Resources\‌​PDF_Books\", cboPDF.SelectedItem.ToString());
 System.Diagnostics.Process.Start(w);
