Using Visual C++ 6.0 MFC in SDI application
I don't understand how to clear the client window that I had been drawing in when the user selects the menu item "New" from the main File menu. What code should be used to clear the old window and where should that code go?
Thanks!

You can update all views then put a handler in View class and clean the view in the handler.

Hello all,
I am working on Client Server architecture.In this multiple servers,
multiple Clients can be there.I am facing one problem here please suggest some solution for that....
take an example If I have two servers running on two different computers A & B.I have database on computer A. Both servers are connected to same database which is lying on A. Now if my A server has done some operation like Add or Delete data in database then How it can be reflected in Server B cache.
I mean how server B can be intimated that this operation has been done so it can get that perticular record only from database.
I can't take all data because I have around 5 lakhs of records in database so fetching all 5 lakhs records for one single record is not feasible & it will take too much time also.
So is there any other way than broadcasting and changing in database.please suggest me.

I have SQL Server 2005 instaled in a server system
Can I programatically connect to this database system (using a VC application .exe) and execute
a SQL query to create a table and insert/update few records into it.
Do we have MFC Classes and appropriate member functions to do the above task ?
Thanks in advance.

ODBC, ADO database connectivity- CDatabase, CDaoDatabase class etc. will help you.
Somethings seem HARD to do, until we know how to do them.

I have a Visual C++ program which has compiled and run many times through various editings.
Suddenly today it has started faulting with these 16 unresolved externals. What is happening?

Did you import gdiplus.lib?
|
|
|
|
|
You probably forgot to link against gdiplus.lib.
|
|
|
|
|
Thanks; please how do I link against gdiplus.lib?
|
|
|
|
|
Depends of the IDE you are using. For VC2005: open your project properties -> "Configuration Properties" -> "Linker" -> "Input" and add "gdiplus.lib" in the "Additional Dependecies" option.
|
|
|
|
|
put this in your stdafx.h under your include.
#pragma comment(lib, "GdiPlus")

Thanks. #pragma comment(lib, "GdiPlus") works.

Guys,
I have a small problem.
Our product, a monstruous C++ application (MFC I think) provides functions for automation. It allows you to create other applications that can click a button, set/get text from various controls etc...
One of the things I do in code is read out a column from a list. (CListView??)
This is where the problem lies, occasionally, apparently completely random and without any clear reason (at least, not as far as we could discover ) it fails to read out the value although there is one in the list. I have never ever been able to reproduce it on my Dev machine (Xp), but on the test machine it happens (Windows 2000). After some analysis I figured it must be some data corruption, because if you refresh the data from our application it suddenly works correctly again (refreshing takes too long so we try to avoid it).
Question: Could this be Windows 2000 related? Maybe it's fixed in a SP?
I tried google, but I'm not sure what to search on...
Many thanks.

Does your application log events? Have you tried using an external debugger (like DebugView[^]) with OutputDebugString()[^]?
Besides that, providing concrete information - like it *is* an MFC project, the control *is* a CListView, etc., would be more beneficial (to you, for sure, and to the ones trying to answer you as well)

mm, you're right. I should have given more info.
It's definetely MFC, of that, I'm pretty sure (99%  ).
If I get the properties of the List it just says List Control. (CListControl should then be the class, right ?).
To find the actual code behind will be very, very hard as it seperated from the GUI (and as said in original post, "monstruous").
It logs tons of things, but we were never able to find the exact cause. We did add additional logging, now we have to wait until it actually occurs again.
The only thing I am sure of is that it cannot read the line correctly for some reason (in rare cases). The only link I have found thusfar is Windows 2000 as I never got it in Windows Xp. (but it could be something else)
thanks
PS: I know it's probably not detailed enough, but that's also the only info I've got.... I understand if you can't help me with this info .

You'll probably have to code this yourself with GetWindowPlacement(), SetWindowPlacement() and storing the coordinates in the registry.
Have a look at the code in "ResizableState.cpp" from this library:
