clear type/click ahead buffer VB.NET

Hi.

We have developed PDA applications using VB.NET cf2.0. is it possible
to flush the type-ahead buffer when a new form is opened?

We have impatient users who may tap a button on the screen which opens
a new form but before the form opens tap the button again. if the new
form has a button in the same place as the first, the second tap
selects the button on the new form.

Thanks. Ian.

We use a simple hack to get around this problem. On each form we
create a boolean value that we check during events.

private bool m_InProgress = false;

private void Form1_Load(...)
{
m_InProgress = true;

// do work ...

m_InProgress = false;
}

private void Button1_Click(...)
{
if(m_InProgress) return;
m_InProgess = true;

// Handle event

m_InProgress = false;
}

Sorry my response was in C#, but the same logic should work in VB.

Thanks Jerod.

We'll give this a try.
