I think one way is to use FindWindow() and use your window class,if it find it then do not attempt your application to proceed.

CString::Format();
- Anders
Money talks, but all mine ever says is "Goodbye!"
|
|
|
|

CString.Format(wada wada wada)
or
sprintf(wada wada wada)
then
TextOut(blah blah blah)
then apparently you will have an uncle called bob

"good morning ... how many sugars do you take in your coffee ... and what was your name again?"
coming soon: situations to avoid #38: "...and the dog was there too?"

Can these functions write to the view?
YES, I am here.

The first two that Lauren mentioned will format the data in your string into another buffer, then you can use TextOut to draw to your view. You should place the call to TextOut in your OnDraw handler if you are using MFC, or in your handler for WM_PAINT if you are using regular window 32.

you would normally either let your user type directly into the view (like a text editor) or enter stuff thru a dialog box
then in your OnPaint() handler you would put the other code

Hi,
I have an SDI project (doc/view architecture), my view is derived from CFormView which contains a ListBox.
I wish to ask the user to save the application data (the content of the ListBox) when exiting or when File/New menu command is selected.
How to do that (save the content of the ListBox) ?
(I know that i should save it's content to my CDocument... but how to do it exactly ? step by step ?).
Thank's

Overriden Serialize,and define strings for your listbox and do something like this:
void CTestAppDoc:: (CArchive& ar)
{
if (ar.IsStoring())
{
ar << m_string;
}
else
{
ar >> m_string;
}
}

You can use doc's default serialization feature if your know the kind of data and the exact size of your data. Otherwise, you should override all save, saveas, save file, etc. and write your own read/write functions for input and output.

The font of a CEdit box can be changed with SetFont(..), but that function doesn't change the Background color of the text.
How on earth can I change it, I'm getting pretty desperate, as it appears there is no function that does the job properly.
And subclassing a control will result in rewriting almost the entire paint process of the CEdit class.
I need to do the same with Group boxes.
Who can help me out? Any help would be greatly appreciated!

Hi!
I have drawn three radio buttons, and want to set one of this three one to aktivated state. How can I do this???? Please Help me soon, I need it for a project at school! 
thx Michi

If you have used Visual Studio to generated the dialog you will have set the first one in the group with the WS_GROUP style.
The easiest way is to use Visual Studio the attatch a variable to the auto radio button group. Set the variable to 0 to avtivate the first,
1 for the second and 3 for the third. Then call UpdateData(FALSE);
Happy programming!!

first you need to make them all part of the same group in the dialog editor
then you need to assign a variable with them in the class wizard
then you need to set the variable to the zero-based index of the button you want on in your data exchange code
