Question and Answer Database FAQ1024C.txt How do I read a change in a control at runtime Category :VCL Platform :All Product :C++Builder 1.x Question: I need to read the change and write to other control while the dialog is displayed. For examples: there is a group box with two edit controls A and B. When A is modified, we want to update B accordingly. If we use Execute command then we can read A and B but we cannot read and write to A or B. Answer: In your class derived from TDialog, process the EN_CHANGE message. The procedure for this message will get called when the user modifies the edit control. You can then read the control, and write a new string to the second control. 5/18/98 8:49:38 AM
