how to check whether control exists

[bobek]

How to check if any particular control exists on a screen?

Ususally, all control of a window are displayed immediately after activating window but not in my example.

Im creating a new window and controls(objects) are retrieved from database which takes some time and then displayed in window.

Therefore it doesn't work:

WinWaitActive("login")

ControlSend("login", "", "OK", "{ENTER}")

Right now Im adding one additional line and tell app to sleep [e.g sleep(2000)] but it's not a nice and flexible solution

do
until ControlGetHandle ( whatever )<>""

edit: nm guess larry got it

That works fine, thanks guys!!

However, i have trouble with identifying controls.

ControlID is different everytime i run project, ClassNameNN remains the same, but is different on different computers the project is working on.

i can use text property for buttons but what about textboxes and so on?
