Alt+F4 will send a WM_CLOSE message to your application. You may consider handling that message.

Hey guys,
I got a question abotu variable passing again.
In my OnNewDocument function call, I store the filename into a CString called FileName. Then I call an UpdateAllViews.
In my OnUpdate I use this:
CDisplayDIBDoc* pDoc = (CDisplayDIBDoc*)GetDocument();
if (pDoc)
{
m_Dib.Load((LPCTSTR)pDoc->m_Filename);
InvalidateRect( NULL, TRUE );
UpdateWindow();
}
This takes the FileName and passes it in the load function so I can load my DIB.
All this said, I want to pass the same string to my new Child Window so that it's OnPaint will also load and then draw the same Image.
What I need to do is pass FileName from the Doc class to the ChildWindow class. I tried using the above code in the new ChildWindow class, but I get an error.
It says that GetDocument()is an undeclared identifier.
My question is:
How do I pass this string to the appropriate class?
Do I need a getDocument function for the ChildWIndow class? It is a CMDIChildWnd class. I look in Class Wizard and there is no GetDocument for me to "add Function". There is also no OnUpdate. SO should I create my own GetDocment or OnUpdate functions?
Thanks a lot,
Sorry for the ong winded question

Doesn't GetActiveDocument work?

I don't suppose I could trouble you to show me an example of how I could use that?
Thanks,

Never mind! I was being lazy, but I found good documentation. You were right, like always.
Now I'm rolling again!
Thanks so much!

Boy I feel dumb today. I know I have seen an article on here that tells me how to keep a dialog as the top window, but I can't seem to find it through the search engin or my manual search. If someone could be so kind and point me to a good arctile I would be very grateful.
Here's to bad days.

Check this...
::SetWindowPos(hwndDlg, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
... or, if you're MFC type, this:
dlg.SetWindowPos(&CWnd::wndTopMost, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);

Its looking like the strlen of a char* variable populating a richeditctrl via SetWindowText is 2047 (yes I fine tuned it to exact). Any larger and it wont compile - string too big. I need to have the user enter his stuff directly without having to manipulate it by code (in case strcpy and strcat work - wil try next), so any views on this limit?
Thanks,

Actually thats where I started. I have a callback and StreamIn function but theres never any output in the RTBox. I have some sample code that I can post if you would be interested in looking at it.
Thanks,

Hey all,
This is probably the wrong place to ask, but...
Anyone know of a (really simple) application/library that can take a series of 3D coordinates (1 set of coords for each second, for example) and render it as an animated point in 3D space?
I need this to test the output of my app, which uses fancy photogrammetry to derive an object's 3D position based on it's position in 2+ camera's image-plane.
I need something that is as simple/quick to set up as possible, cos I can't really afford to spend loads of time learning OpenGL/Direct3D, etc.
Any pointers?
TIA,
Pete

You could write out a VRML file and use a free VRML viewer.

There is one called Scenelib that is pretty easy to use and is based on OpenGL. I can't remember where it is right now but it should be easy to find with your search engine of choice.

Hi all !!
I am developing an instant messaging server which will also connect to databases. I am a newbie as far a data access in VC++ is concerned.
Now i want to connect it to database server (client/server model). Please suggest me the best data access technique considering the requirement of my application as follows:
My application is DOS based, 90% complete and written without the usage of MFC.
I want to access data from sql-server based machine running on my network. My target is to access data quickly and efficiently though accuracy can be compromised.
Programming ease is also a requirement.

ummmmm u tend to get out exactly what u put in with these damn database things ... wish they could give us human storage devices huh?

DOS as in MSDOS app or DOS as in Console Application?
If it is a console application, look at some of the ADO articles available on this site.

Hello!
I'm working on an application where a binary file must be loaded and should be kept in
memory during all execution. I guess that keeping data in physical memory and avoid memory swap on virtual memory is not possible.
Is it a way to keep the whole address space that concerns my application in physical
memory?
Thank you for any information !

For NT-based systems, seems like <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/kmarch/hh/kmarch/k106_8ble.asp">MmProbeAndLockPages<a> is the API you're after. For 95 and relatives, have a look at LinPageLock in the DDK documentation.

Hi All,
man, you know its Monday......
yes, i will lash myself after this.
i can't belive, i've gone brain numb on this. I need to trap wm_quit/wm_close or any systm messages that will cause my app to shutdown, so i can check if my app is ready to shutdown ,and prevent this from happening unless certain conditions are met in my app.
i've tried the OnCmdMsg --> if pMsg->message == WM_QUIT etc....
with no success.
is this suppose to go in the main app .cpp file or the mainfrm.cpp
Thanks in advance
lost, stupid and confused
Fred

if you override the OnClose() handler and simply return without executing the default handler if you don't want to close
