Updating a Static control

Updating a Static control

Updating a Static control

I have an application that starts a thread.  In that thread I open a dialog box in modal mode.  Then I try to update a Static control.  Here are some code snippets.

This is in the main dialog:


CTest Test;
hTestSequenceThread = (HANDLE)_beginthread(Test.TestSequencer, 0, (void*)this);

This is in Test.TestSequencer:


INT_PTR nResponse = LED.DoModal;

Then in the child dialog box in a function called by the constructor:


CStatic* promptmessage;
promptmessage = (CStatic*)GetDlgItem(IDC_PROMPT);
promptmessage->SetWindowTextA("Prompt Message");
The GetDlgItem() line gives and assertion

Alternatively, I added a member variable m_Prompt then used the following in the function:


m_Prompt = "Prompt Message";
Here the UpdateData() function gave and assertion.

How do I access the controls in the child window from the child window?


If it ain't broke, it probably needs improvement.

RE: Updating a Static control

Static is "static" !

Workaround this, using a normal Edit control,
removing box (frame) and setting backgrond as the dialogbox:
declare it read-only, no tabstop. winky smile


RE: Updating a Static control

Don't do it in the constructor.  Do it OnInitDlg().  The objects don't necessairly exist yet.
