or pass a pointer to the main window to the child dialog.
or use the observer/observable pattern.

yep got it.... the problem is I am including the header file of my child dialog in my DOC header file and when I try to define a pointer to to a doc object in my child dialog's header file by including the main frame's header file in it, it gave me error of undefined symbol error. Then i tried to include the child dialog's header file in the main frame's cpp file and now its working fine.
thanks for your replies.

I've got a full screen dialog application in which i want the user to be able to drag any dialogs which pop up to any position they want on the screen but also to limit them from certain areas of the screen. I've used the following article http://www.codeproject.com/dialog/dragwindows.asp?df=100&forumid=4307&exp=0&select=1749703[^] for the dragging of the dialog (using the OnNcHitTest method). However I can't figure out how to limit where they can drag the dialog. I've though it would be a simple matter of converting the CPoint position for the mouse into screen co-ordinates and checking if it is in a forbidden region and then setting it to be outside of this region.
Any suggestions?
cheers,
Andy

ok, found my first mistake, was looking at the x part of the CPoint instead of the y! 
I think I've figured the problem, the OnNcHitTest only seems to be called when I've released the left mouse button, so during my drag it doesn't get called. Is there anyway around this?

That's because the system enters a modal message loop for the duration of
the drag.
You may want to take a look at the WM_MOVING message.

Hi thanks for your reply, I've got the solution now, all I had to do was re-read the article I linked to in my orignal post and implement the OnLButtonDown, OnLButtonUp and OnMouseMove methods instead of the other one and do my region check in the OnMouseMove method.

Hi, i have SDI app and CDialog based window, i need to scroll client area if something in window is larger than window itself. I overwrite DoDataExchange() function and add :
SetWindowPos(&wndTop, 0, 0, 800, 500, SWP_SHOWWINDOW);<br />
if(x==2){<br />
ShowScrollBar(SB_BOTH);<br />
SetScrollRange( SB_HORZ, 10, 5000);<br />
SetScrollRange( SB_VERT, 10, 5000);<br />
}<br />
But i can't scroll client area.
In previous app i use CFormView derrived window and overwrite OnUpdate() function using this code :
<br />
void CResize1View::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint) <br />
{<br />
if(((m_iLiczbaBut+1)*50)> 400){<br />
SetScrollSizes(MM_TEXT, CSize(780, (m_iLiczbaBut+2)*50));<br />
}<br />
else{<br />
SetScrollSizes(MM_TEXT, CSize(780, 500));<br />
}<br />
<br />
}
It work corectly in CFormView, but this time i need the same in CDialog but i don't know how to do this. Please help.

Hi zarraza,
It is possible (if I recall correctly). I believe I found a sample floating around the web a few years back. The details escape me. Sorry.

I seem to be pulling my hair out. Maybe because it's easier than I think and nobody seems to need help with it, but I am trying to get 2 pieces of data out of my bridge using SNMP and display them on a window.
Problem is, I can find no libraries or code projects that seem to address this in any detail. Is it that difficult?
I am an old C programmer than is getting back into prgramming and I like vc++ and am just learning it, so maybe its just me : /
Seems like there could be a function where you send it the MIB octet and get your number back:
unsigned long in GetSNMP(octect *sOctet);
Thanks

So you are developing this for Windows? If so you want to look at the WMI API. There is a SNMP provider available and the API provides the Read/Write operations you seem to be asking about. According to the documentation the provider is not available on 95/98 OS.

Yes it will be a Win32 app.
I'll take a look at that. Thank you.
So far I am just reading my MRTG log files for the data but, for obvious reasons, want the app itself probe the bridges for data.
I was concidering making a console based app that probes and uploads the data into SQL, and then the Win app reads it and reacts from there. This could be done with two win apps as well, with one running as a service. But in any case, I must be able to get the SNMP data. ; )
Thanks again

hai all,
i will narrate an example, there by convey my doubt.
in my edit box, the fifth character cannot be an alphabet.
so if the user types 1a34 and D,
i have to delete D from the string in the editchange event and replace the string 1a34 there, such that, the user can type a valid fifth character.
here the problem iam getting is, if i do like this, the cursor is placed at the starting of the string.
now is there any technique, suchthat, i can set the cursor at a required position?
thanks for the opinions.

You can use the EM_SETSEL message (CEdit::SetSel()) to position
the caret in the control.

It sounds like you need a masked edit control. See here and here.

Very good I hope you find answer early.

Thank you all the same!

Hi,
I know that the most obvious answer is "check it out" but...
If I code a dll with some functions and, in a part of the main programm, I use it with
MyDll::MyFunction ();
if the DLL is not present when it is supposed to be... obviously the function won't be called, but will the programm give an assertion? or just try the line and go on as nothing?
I have already coded the functions in my program, that should be in the dll. The functions work, but I have no experience with dll and I would like to know the best way to use the functions only when the Dll is there, but having no problems when it is not there.
I have thought to check an easy
CFile f;
if (f.Open ("MyPathToDll\\MyDll.dll", CFile::modeRead))
{
f.Close ();
MyDll::MyFunction ();
}
else
MessageBox ("This function is only reachable if the \"XXX.dll\" is present on \"MyPathToDll\", "Info", MB_OK);
Is it "good"? Which methode is the apropiated one?
