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.
