This is a WPF app with the latest version of the .NET framework and VS2015 on a Win 10 box.

I am trying to use the "CommonOpenFileDialog" from the Windows API code pack 1.1 to allow the user to establish a folder in which to do some stuff. The folder can be either an existing folder, or a new one that the user specifies.

If the user wants to create a new folder, then I want them to be able to specify the folder by editing the text within the "Folder:" textbox at the bottom of the dialog. Within this context, the dialog would just be a means by which to navigate to the folder in which the new one is to be created. My plan is to validate the input within my code to check for a valid (existing) path, and simply create the path if it does not exist.

Here is the code:

   private void test1_folderSelectorDialog ()
   {
       if (CommonFileDialog.IsPlatformSupported)
       {
            var folderSelectorDialog = new CommonOpenFileDialog();
            folderSelectorDialog.EnsureReadOnly = false;
            folderSelectorDialog.IsFolderPicker = true;
            folderSelectorDialog.Multiselect = false;
            folderSelectorDialog.EnsureValidNames = false;
            folderSelectorDialog.EnsurePathExists = false;
            folderSelectorDialog.EnsureFileExists = false;

            folderSelectorDialog.InitialDirectory
                 = "C:\\My_Initial_Directory";

            folderSelectorDialog.Title = "test1_folderSelectorDialog";

            if (folderSelectorDialog.ShowDialog() == CommonFileDialogResult.Ok)
                TxBx_folder.Text = folderSelectorDialog.FileName;

            this.Focus();
       }
       else
           MessageBox.Show ("CommonFileDialog is not supported");
   }

When I run the dialog and modify the text within the "Folder:" textbox, then press "Select Folder", the dialog validates the input and issues a dialog popup with the message:

"Path does not exist. Check the path and try again."

Please note that I have set "EnsureValidNames", "EnsurePathExists", and "EnsureFileExists" to "false". (If they do not control dialog validation, then what are they there for?)

I can right-click on the dialog window and use "new > Folder" to create a new folder (which is what I'll have to do if I cannot resolve this issue), but I'd rather do it the way that I am trying to do it, as it seems much easier and more intuitive to do it that way.

How do I get the silly thing to shaddup and just accept the input without passing judgement upon it?

Thanks!

If you want the user to select only the folder, then below code is enough 

CommonOpenFileDialog dialog = new CommonOpenFileDialog()
dialog.IsFolderPicker = true
if (dialog.ShowDialog() == CommonFileDialogResult.Ok)
{
    filesPath = dialog.FileName
}

I believe below things are not required

folderSelectorDialog.Multiselect = false
folderSelectorDialog.EnsureValidNames = false
folderSelectorDialog.EnsurePathExists = false
folderSelectorDialog.EnsureFileExists = false
