Addin for OneNote: Unable to use folder browser

Question

Since my previous post was closed due to a lac of information, I'd like to start a new one....

I'm developing an addin for OneNote 2010 which opens a Windows Form. I used this site as a guide. Everything works well: Forms are shown, statements are executed and pages are filled by information I want...

I'm having trouble by showing the folder browser. I want to put the selected folder in a textbox or label for further use, but when I press the button, the form hangs. The only way to stop this is using the Windows Taskmanager.

For showing the Folder Browser dialog, I'used the component placed on a form and by code, none of them works.

Here the simple code for showing the dialog:

C#

FolderBrowserDialog fd = new FolderBrowserDialog();
fd.Description = "Please choose";
if (fd.ShowDialog() == DialogResult.Cancel)
{
    this.Hide();
}

txtFolder.Text = fd.SelectedPath;

Let me know if there if more information needed.
Kind regards,
Piet

I think the explanation may be simple: this.Hide(); hides your Form.

Try:

FolderBrowserDialog fd = new FolderBrowserDialog();

fd.Description = "Please choose";

if (fd.ShowDialog() == DialogResult.OK)
{
    txtFolder.Text = fd.SelectedPath;

    // continue with code based on having
    // a valid folder reference
}

So, a lot depends here on what the "this" in this.Hide(); refers to.
