One approach I've seen is to add all the controls you'll need to the form before hand, but without the 'Visible' attrib. Then you just get pointers to the controls you need and ShowWindow(SW_SHOW) - maybe positioning them as well, depending on how cluttered your form gets in the resource editor.
An array of control IDs for each pane type could be useful both for the display and later data retrieval.

Hello All,
In my App. I have the full Path and the Full name of a File, So I was wondering if there is a way (or an Win. API) to get or Convert this Full Qualified Path to its Dos format.
Thanks in Advance for your Help

How can I convert a CString to a char *

Why would you need to when operator char * is overloaded ? You can just pass in a CSTring. However, GetBuffer will give you access to the underlying data if you need it - don't forget to call ReleaseBuffer afterwards.

You can do the following:
CString casa = "casa";
LPTSTR string=casa.GetBuffer(256);
char *character;
character=string;

First cast it LPCTSTR then to char * the code would be like this.
(char *)((LPCTSTR)strSampleString)

I have a dlgbar in mainframe, with its resident controls accessed directly by cmainframe ( as modeless dlg ). The problem is that certain user actions on the dlgbar ( closing it via the system close icon, or moving / resizing it ) need to cause additional action. I have tried deriving a class from CDialogBar to manage the bar and adding to the message map to trap these actions, but do not seem to get any effect, except during program initialization or shutdown.
( eg: I tried processing wm_destroy in CDerivedDialogBar and got an effect only when the program terminated. I tried processing wm_close and got no effect at all. )
Anyone know what messages I need to process or how I can trap these actions?
This is driving me nuts trying to find solutions.
Thanks

CControlBar-derived objects (including CDialogBars) are not destroyed when you click on the 'x' icon - MFC just hides them. To trap this event, you can override virtual method CControlBar::DelayShow. The function is undocumented, but worked OK for me.
What kind of problems are you having with resizing? No WM_SIZE message?

Thanks. That sounds like it might be what I need, but what are the parameters for DelayShow()?
As for the other, it's not a problem with resizing as such, but rather a result of any user action on the dlgbar window itself. This particular bar is set to float or dock, and it contains a listcontrol which is its main feature. Whenever the bar is moved, the input focus switches to the bar itself, and stays there. I need it to return to the listcontrol after the move is complete ( as soon as the mouse is released ).
Thanks again.

> what are the parameters for DelayShow()?
It's declared like this in afxext.h:
virtual void DelayShow(BOOL bShow);
Are you using 'raw' CDialogBar or some derived class?

I'm using a derived class with one additional member -- a boolean flag representing the bar's visibility state.
Thanks again.

There are a couple of ways to take care of this problem. I'll tell you about the way I solved it in my project a couple of weeks ago...
The GetInput function gives you the content of the input buffer and it resets the input buffer to empty (that is, if you do it correctly in respect to VARIANT types... I told you this a few weeks ago). Now you can choose to work on event-basis or on time-basis. If you work on even-basis, you have to catch the 'input buffer threshold reached' event. You can program the 'GetInput' function right inside the event handler and store the received character(s) in a string member variable. If you choose to work on a time-basis you will have to start polling the size of the string already in the inputbuffer. Don't forget to program a time-out procedure in the latter case, because if you don't and the communication gets messed up, your program will hang!
Now, in either case, you have to think of some wat to package your communication. I packaged my messages inside STX and ETX commands (some low-value ASCII characters). You can then extract the messages from your member string variable by searching for ETX commands (you can use whatever you want of course, even \n if you like).
Hope this helps a little!

Answering the phone:
1) Wait until it rings
2) Pick up the horn and say your name, preferably 'goodmoring' as well
Just kidding Now this is how your modem should do this:
First you have to set the DTR to true. Don't ask me why, you just have to. You can use the SetDTREnable(true) function for that.
Then send the next message to the modem:
ATE1S0=1
followed by a carraige return - line feed again.
Now it will pick up the phone (if everything's okay, you will probably see the AA light on your modem light up... Auto Answering mode).
Now you're gonna have to poll the input buffer and as soon as you get a message from the modem (ended by a carraige return - line feed) which starts with the string 'CONNECT ', then you know the handshake has succeeded and your connection is open...
Good luck!

Hello again to you too,
I'm doing fine, thanks. What about you? I'm starting to get curious about the sort of application you're building at the moment... If it's not too rude sticking my nose into your business
Anyways, I've left the MSComm story a month ago and am now busy programming some ASP-website.
About your question, this function looks like some weird windows-messaging function. I think it's probably a GUI-related function from the example. Shouldn't worry about it too much. I never used it and my application is working great.
Good luck!

Using Visual C++ 6.0 and MFC
I have populated a CEdit control programmatically. Sometimes the text is longer than the display area.
Can anyone please tell me how to issue a command to scroll back to the start of the text. Currently it always scrolls to the end.
Thanks in anticipation
Sara

How did you get the such a strange behaviour ... ?
I've just created a MFC dialog-based app with a single line edit control and I tried that code:
1)m_edtText.SetWindowText("I'm the man with the mission");
and that:
2)m_strText = "I'm the man with the mission";
UpdateData(FALSE);
and all works fine (it means - I can't reproduce your app behaviour =).
Anyway - try this code:
m_edtText.SetSel(0,0);
Hope it will help you.
Best regards,

Calling the CEdit member function SetSel(0, 0, FALSE) will scroll it so the first character is visible.
