- The popup window is opened below the control that calls OpenPopup. If there isn't enough room to open the window, it will either open above the field, or below the field to the left.
Parameters passed to the window to open The parameters are retrieved in the "Global declarations" event of the window. The first line of code of this event must correspond to the following line: PROCEDURE <Window name> (<Parameter1> [, <Parameter2> [, ...]])
Limitations - OpenPopup must be executed from the code of a control.
- The control that calls OpenPopup must be visible.
- Non-modal windows cannot be opened from a popup window. Open must be used to open a window. Opening a modal window from a popup window does not automatically close the popup window. In this case, you must process the return value of Open and you must use Close to close the popup window.
- A popup window cannot be opened from another popup window.
