Multiline Property Problem

We have made an Enhanced TextBox to assign some additional properties & methods to it. The existing VBTextBox properties also have to be added thru the ActiveX Wizard. There is a problem with the Multiline property. Multiline prop could not be assigned at run-time & even assigning it at design-time is not working. What may be the problem?

Well, you've got two choices. You can change the existing textbox at run-time using API, or you can have two textboxes. One that is multiline, and one that isn't. And just bring the appropriate textbox to the front when the property is changed.

:)

Can anyone let me know API for changing the Multiline property at run-time?
