Anyone know how I can take a dialog box with 3 buttons that have no function at all and change the background colours of 2 of them to red and one gray??

Thanks.

Try adding an OnCtlColor (if MFC) handler to the dialog and returning a brush of the desired color based on the control IDs...

Or you could try using CButtonST v3.4

Actually, I was asleep at the switch in that reply - but if you search the articles here for 'owner draw' you'll get lots of info on what can be done.

how would i do that?

custom preprocessor

22-Mar-02 5:04

hi,
I want to execute different functions depending on the condition set.I know it can be done with function pointers but I want to do it with preprocessors.
How to get about with it.
Cheers.

The standard approach is like this:

#ifdef SCENARIO1
f1(...);
#elif SCENARIO2
f2(...);
...
#else /* SCENARION */
fn(...);
#endif

Then in Project->Settings->C/C++->Preprocessor definitons set the appropriate macro depending on the scenario/configuration you wish to select.

If your edit box is in a dialog OnInitDialog()

editbox.SetWindowText("1");

No,you have to define controller for it,tell me if you use VC6 or VC7 to tell you how to this task. Smile | :)

Go to class wizard(prees ctrl+w)

Go to "Member Variables" tab.

In the Class name box, choose your dialog class.

In the Control IDs box, click IDC_YOURTEXTBOX.

Click "Add Variable". The "Add Member Variable" dialog box appears.

Change the Category box from "Variable" to the other one.(I can't remember the exact name now)

In the Member variable name box, type the name you want,and its the name of your control,you should use this for SetWindowText()

CView type in a dialog...whats the problem

22-Mar-02 4:59

My question is
Whaaaaaaaaaaaaaay. Confused | :confused:

puhuleeeeeeees help.

Re: CView type in a dialog...whats the problem

Is the CView object declared as a member of the dialog class.
If so try creating a heap object. Means instead of a CView member, use a CView* member. The CView classes call a delete this in the destructor or just before the destructor [dont remember exactly] and this often causes problems for stack objects [even member objects of other objects]
