Question

This code opens a folder if the “TotalFileCount” == 0. I want to open the folder and have it centered on the screen and I want it to be a specific size. Is there a way to do that in C#?

if (TotalFileCount == 0)
{
    MessageBox.Show("There are no files in this directory. Please add pictures to this folder: " + AppVars.PolicyImagesDirectory + " and try again.", "Error!", MessageBoxButtons.OK, MessageBoxIcon.Error);
    btnBrowse.Focus();

    System.Diagnostics.Process process = new System.Diagnostics.Process();
    process.StartInfo.FileName = AppVars.PolicyImagesDirectory;
    process.Start(); 
 }

When the new Windows Explorer window opens, can I make it a specific size and center it on the screen?

Answer 1

get the handle from the process then call the native SetWindowPos from the win32 api

process.handle //to get the handle of the window.

[DllImport("user32.dll", SetLastError=true)]
public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int W, int H, uint uFlags);
