DDX for CStatic

[jc]

Hello,

I defined a CStatic variable,
and I am trying to use the variable with
DoDataExchange. But, I always get a runtime
error ( I want to change the text of the static control).

CStatic m_strCtrl;

DDX_Control(pdx,IDC_STATIC1,m_stcCtrl);

...

m_strCtrl.SetWindowText("Test");

TIA,
-jc

Are you compiling as Unicode (of course then you should get a compile error,
but I figured it's worth asking).

Also, you need to do this call in OnInitDialog() after the call to
UpdateData() or the base constructor has been called.

Tom,

Thank you for taking the time to reply to my posting.

Yes, that worked!

I have no idea what you are talking about. There IS NO SUCH THING as "a runtime error".
There is a SPECIFIC error with SPECIFIC text that occurs at a SPECIFIC line of code!
Unless you report EXACTLY WHAT ERROR YOU ARE GETTING AND WHERE YOU ARE GETTING IT, and
report the values of all the variables involved in the error, and show what the values
were at the call site, you are wasting your time and ours with a post.

At no point have you explained what you have done. You have not shown where the CStatic
is declared (is it in the class?), you have not shown the control ID associated with
IDC_STATIC1 (which is a LOUSY name for a control!), you have not shown any context where
the error occurs, you have not shown where the SetWindowText takes place, and overall this
is not a coherent question. You missed showing EVERYTHING that might actually help us
answer the question!

But why? If the goal is to set the window text, why use something as strange as DDX_Text
(which requires calling UpdateData) when a much simpler call to SetWindowText of a control
variable would work.

Providing, of course, that all necessary preconditions are met.
