Hello all,
I am developing a custom combobox control. When the user presses ENTER the combobox will match the characters entered in the box with record(s) in the database and then bind the combobox with the resulting cursor. Currently I have 3 problems.

When the user presses the ENTER key, my query executes, but Focus goes to the next control. How can I keep FOCUS on the combobox?

Secondly, when the user presses the UP and DOWN arrow keys, I want to move through the cursor. By putting code in the KEY PRESS event I can make this happen, but Focus goes to the next control each time the UP or DOWN arrow key is pressed. So I need to keep FOCUS on the control again.

Third, once the query executes, I would like to programmatically drop down the combobox list. How can this be done? This may actually solve the second problem, because the UP and DOWN arrows keys work properly when the combobox is in the drop down mode.


The way this control works. The user is allowed to search on 3 fields or a combination there of. The fields are designated by certain keys, like to search on the second field - a comma must be entered pre data. A dash must be entered pre data before the third field. The fields can be of character type, integer numeric type, or date type. Once I get it working properly, I would be happy to let others use it. Thanks for the help.
