Hi Stephane,
Thanks for the PInvoke code you provided. I tried to repro your problem
(using your code combined with the code below), but I'm not having any
luck. I've tried both generic wince 4.2 and 4.1 images and PPC 2003
images. Let me know if you discover any new information after the holidays.
Repro:
public class TestForm : Form
{
public TestForm()
{
Button btn = new Button();
btn.Text = "Hide";
btn.Location = new Point(5, 45);
btn.Click += new EventHandler(OnBtnHide);
btn.Parent = this;
TextBox txb = new TextBox();
txb.Parent = this;
txb.GotFocus += new EventHandler(OnTestFocus);
this.Text = "Bug";
this.MinimizeBox = false;
}
private void OnBtnHide(object obj, EventArgs e)
{
Keyboard.Hide();
}
private void OnTestFocus(object obj, EventArgs e)
{
Keyboard.Show();
}
static void Main()
{
Application.Run(new TestForm());
}
}

| Katie,
|
| The p/invoke code we use is inline at the bottom.
|
| The scenario is as follows : I start an application with multiple forms.
Only
| one of them is showing (non-modal). When a textbox on the form receives
| focus, we call Show() on the Keyboard class. This in turn calls
SIPShowIM()
| through p/invoke. As I said earlier, there is no menu control on the
form,
| nor is there an InputMethod control.
|
| I'd like to try it out myself in a simple application to rule out a
number of
| other things, but I can't right now (it'll have to wait until after the
| holidays). It's just strange to get this kind of behavior with SP2 as it
| works fine with SP1.
|
| Regards,
|
| Stephane
