Need help communicating with MFC dialog boxes (domodal) [modified]

CoffeeAddict19

Basically what I am trying to do is have two text strings pop in text boxes (CEdit) for the user when they open a dialog box. The problem is that when you call domodal, all control transfers to the dialog box, so everything has to be done before the call. In the past I have just set a flag in the dialog box class to let it know that something needs to be loaded, and placed the information there beforehand, and then called domodal. OnInitDialog gets called when the dialog pops up, checks for the flag, and loads whatever. It seems kind of messy though. Is there another more elegant way to do it? Is there some way I can modify DoModal to accept arguments?

Along these same lines, do you know how to put carriage returns into the CEdit? Yeah, I know, noob question, but I haven't worked much with CStrings and CEdit controls, and I just realized that putting a "\n" into a char buffer then converting it to a CString won't work in a CEdit...how do I do this?

Also, a totally unrelated way of doing this, but may be of use if you're using a DLL, is to create a shared data segment with #pragam data_seg() and put in a global variable in there which will keep track of the number of instances of subscribers to the DLL. Of course your program will have to import the DLL etc, which is not preferable at all, but like I said if you're already using a DLL it's another option.

I think you have to use "\r \r". Edit...sorry that's wrong here...it's "\r\n". http://microsoft.ease.lsoft.com/scripts/wa-msn.exe?A2=ind9709a&L=mfc&T=0&P=10710[^] -- modified at 0:29 Thursday 15th March, 2007

that did the trick...thanks...seems counterintuitive, like I was programming for unix or something...I never even would have guessed that in a million years...

globals are most of the time bad, and can be avoided using OOP data members.
