I am initialising GUI components (in a CMDIFrameWnd) using the code below.
It works fine, except that the CMDIChildWnd child frames are blank at startup. If the user fiddles with the child windows (e.g. stretches them) then the splitter displays immediately appear. What have I missed in the initialisation ?
CMainFrame* pMainFrame = new CMainFrame;
if (! pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
CCreateContext context;
context.m_pCurrentDoc = NULL;
context.m_pCurrentFrame = NULL;
context.m_pLastView = NULL;
context.m_pNewDocTemplate = NULL;
context.m_pNewViewClass = NULL;
CMDIChildWnd* alertWnd = new CMDIChildWnd;
alertWnd->Create(NULL, "Alerts", WS_CHILD | WS_VISIBLE | WS_OVERLAPPEDWINDOW, CFrameWnd::rectDefault, pMainFrame);
CSplitterWnd* alertSplitter = new CSplitterWnd;
alertSplitter->CreateStatic(alertWnd, 1, 2, WS_CHILD | WS_VISIBLE, AFX_IDW_PANE_FIRST);
alertSplitter->CreateView(0, 0, RUNTIME_CLASS(CLeftView), CSize(100, 100), &context);
alertSplitter->CreateView(0, 1, RUNTIME_CLASS(CSsfconView), CSize(100, 100), &context);
pMainWnd->ShowWindow(SW_SHOW);
pMainWnd->UpdateWindow();
cheers,
Neil

What happens if you pass NULL instead of &context to alertSplitter->CreateView()?
Also, this call shouldn't be necessary - pMainWnd->UpdateWindow();
Maybe try without it.
CSplitterWnd* alertSplitter should maybe be a member variable of the MDIChild class (or somewhere)
so it can be deleted, otherwise a memory leak.

Can anyone tell me a way to find out why a program just compiled crashes? And what i mean by crashes, not when its run. But when i try and execute the program i get a Windows error. I've heard of debugging but i have not quite figured it out fully. Or if there is another simplier way of doing this please let me know. Thanx in advance!

You need to place a breakpoint on or before the line where the crash is happening. In your case, you don't know where, so place a breakpoint on the first line in you main(). Hit F5 to start debugging, the program will stop at the breakpoint. Then you can use F11 to move into a function ( your own functions ), or F10 to go to the next line. Keep doing this until you find out where it is crashing then have a look at your variables ( just hover your mouse over them ), one of them will probably be wrong.

hi
im new at C++ and im looking for some help in way that i could understand what un .EXE file loads in to memory and all kind of information i could get like this applications:
http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/ProcessExplorer.mspx
it would be great if someone could help to initiate this learning, if you know a good tuturial that could help me in this way would be great... thank you!!

An exe will load itself and any dll's it requires into memory. If a dll has already been loaded by another exe, it shares it. Depending on the exe, any resources it requires, images text files, will be loaded and unloaded by the exe, but these items will only stay in memory for a short period.
|
|
|
|
|
if you see that software i show as a example, you will see what i mean with checking memory, handles, dll's everything associated... with the file.

Hi everyone;
I have written a MFC application and I want to add a MFC ODBC Consumer class to it. I opened the wizard and selected a data source. When I tried to finish the wizard I have been given a message as "Please select a datasource".
Why am I not able to select a datasource? Could you help me?
Thanks in advance.

Why you cant select a datasource? it shows to you the window that has two tabs File Data Source/Machine Data source
|
|
|
|
|
In File Data Source tab, I selected a data source that I created before but when I click finish button, it says "please select a datasource". I tried with creating a new datasource but nothing changed.
|
|
|
|
|
When You select data source and click ok button what happens
|
|
|
|
|
It returns to the Consumer Wizard. Also class, .h file and .cpp file part of the wizard is not editable.
|
|
|
|
|
Did you see window "Select Database Object"?
|
|
|
|
|
No. I right click to the project name and add -> class. Then MFC and MFC ODBC Consumer. Then, when I press add the wizard is seen. I press Data Source button and I select the data source.

Is the data source valid? Tested? The datasource needs to be able to connect so it can give
you a list of tables/views to make a class for. If the datasource is valid when you select it
then you should get a login dialog (on SQL server, anyway) if the DB requires it. Then you'll
be presented with a list of tables and views available on the database you've connected to.
It doesn't sound like you are getting this far - check your data source!

I pressed "new" to create a new data source. Then I selected MySQL ODBC 3.51 Driver and press "advanced". I wrote:
DRIVER={MySQL ODBC 3.51 Driver}
SERVER=localhost
DATABASE=test
UID=onur
PWD=pass
Finally I saved it under Program Files/ODBC/Data Sources
No any error it gave. However, if I dont write the above parameters, it doesnt set up a connection. What is the problem with those parameters? Could you help me?

I'm trying 
Does the database "test" exist? It needs to be created and have at least a table or view in it.
What if, instead of using the Advanced button, you choose the driver, click next - I haven't used
MySQL so I don't know, but other database drivers provide their own dialogs for setting up a
datasource.
I don't know what kind of ODBC interface MySQL has but with SQL Server it gives you a chance to
test the datasource connection as well.
Assuming you've setup your new data source correctly, you'll need to select the new datasource to
proceed with making your ODBC consumer class. I still don't think you're getting this far though.

The database "test" exists and has tables in it. I think the problem is with the parameters.
|
|
|
|

Yes.
Because I have no life, I downloaded and installed MySQL.  I've wanted to try it out anyway.
Here's what I did:
Right click on project, choose add class
Select MFC/MFC ODBC Consumer
Click Data Source... button
Click Machine Data Source Tab
Click New Button
Select which type of data source - User or System
Click Next button
Select MySQL ODBC 3.51 driver
Click Next
Click finish
You should see MySQL's ODBC connection setup dialog - Fill in all the info on all tabs
Click the test button - if not succesful fix the info in the dialog
If successful test click ok
You're back at the select datasource dialog - Select the datasource you just created
Now, seeing it in real life - I did a googly search and found this...
