Next, we add the status bar message just after the first
if
statement.
lblStatusText.Text =
"Querying Map... please wait for results."
;
Application
.DoEvents();
And we add the completed message just before the closing brace.
lblStatusText.Text =
"Query finished."
;
Before we go any further, some of you will say, "Wow, what a long method," and wonder
why I'm using
Application.DoEvents
to make sure the label is updated in an event
handler. Please remember that this is example code only; it's not supposed to be a perfect
example, or simply copy and pasted verbatim to make production-quality apps. Its purpose is
purely to show you how to use SharpMap to create a simple GIS application.
