That is a Microsoft C++ exception. Set your debugger to always break on this exception and you should find out where it's coming from.

Hi,
Bear with me, I am a actually a VB guy, I went to exceptions and selected stop always for this error code. I know that it is breaking when I call a method of OIP22.TLH file, I am confident that am sending the right parameters but it still fails with this exception. Is this get to do with versions of Oracle installed on my machine or nothing??? What is the path you would suggest me to go with????

Hello,
How can I get the size of physical and virtual memory used by a process?
Thanks, Alma

Physical, not from Win32. Virtual, GetProcessWorkingSetSize.

I found the following solution:
<br />
DWORD dwProcessID = GetCurrentProcessId();<br />
HANDLE hProcessHandle = OpenProcess( PROCESS_QUERY_INFORMATION, FALSE, dwProcessID);<br />
<br />
PROCESS_MEMORY_COUNTERS p;<br />
GetProcessMemoryInfo(hProcessHandle , &p, sizeof(PROCESS_MEMORY_COUNTERS);<br />
logit("Using [PM - %d] [VM - %d]", p.WorkingSetSize, p.PagefileUsage);<br />
It needs 'psapi.h' (and 'psapi.lib' if you want to load 'psapi.dll' statically).

I have an MDI application with multiple view classes. Now I want to use one of these view classes in an SDI application. The problem is that in the OnInitialUpdate() function I call Create(...) for some ownerdraw buttons. When I use the class in SDI it will call OnItialUpdate() several times for the same view, for example every time File Open or File New is selected. This crashes the program as it tries to create buttons that allready exist.
What is the simplest method to avoide multiple calls to OnInitialUpdate()? Or, where else should I call Create() ?
To me it seems ridiculous to call OnInitialUpdate several times, the name is an indication that it is a one-off event
Regards, Haakon S.

How about calling your Create() in in the view's OnCreate() ?
|
|
|
|

I tried OnCreate(), and it didn't work. But mind you, it may have failed not because of the buttons Create() functions, but because of the next piece of code, LoadBitmap(). I got an ASSERT because hWnd==NULL. It is a general problem that I want to do a lot of initialisation after the view is created, but before it is visible. And I want to do it once.

As long as your window isn't created hWnd is NULL. Thus you should first call the base class' OnCreate(). When finished, your windows hWnd should contain a valid handle - if not, I'm not certain what to do  .

I've checked it again, and yes, maybe you are pointing in the right direction . But I'm not home free
I've got some CStatic members in the resource template (my view is CFormView), identified as IDC_TOP and IDC_BOTTOM. They are subclassed into CStatic derivatives for color and blinking:
m_stTop.SubclassDlgItem(IDC_TOP, this);
m_stBottom.SubclassDlgItem(IDC_BOTTOM, this);
This works fine in OnInitialUpdate(), but not in OnCreate() . Next time OnInitialUpdate() comes back, I've got an error.

Here's a hack:
add a member variable to your view class
BOOL m_bOnInitialUpdateRan;
Set it to false in your view's constructor
m_bOnInitialUpdateRan = FALSE;
and then in OnInitialUpdate only create your controls if it is FALSE. Be sure to set it to TRUE afterwards.
if (!m_bOnInitialUpdateRan)
{
m_bOnInitialUpdateRan = TRUE;
}
Note: This is not tested, so give it a try. May work, may not

In my MFC MDI app I spawn CDIAlog derived windows from the View class. In the release version, if I close the CDialog, and then exit the whole app, it crashes. Doesnt crash if you exit while the CDialog is still up. ALso doesnt crash if we comment out the PostMessage()and then close the CDialog and exit!!!!Heres the OnClose for the CDialog:
void CImageDisplay::OnClose(void)
{
m_pParentWnd->PostMessage(UDM_UPDATEDISPLAY,m_imageDisplayVectorIndex);
CDialog::OnClose();
}
For the handler that runs when the msg is received by the vIew
LRESULT CSVBoxView::OnUDMUpdateDisplay(UINT index)
{
return 0;
}
SendMessage causes really strange behavior in the whole program, and its not really what I want to do. SO what is so peculiar about the postmessage? It does get sent because you step into the handler when debugging...
Please help!
Appreciate your help,
ns

The signature for the message handler is wrong, it should be
LRESULT CSVBoxView::OnUDMUpdateDisplay ( WPARAM wParam, LPARAM lParam ) the sig used for any generic message handler. It's crashing because PostMessage() puts two parameters on the stack, but the function only removes one, so when the function returns it doesn't read its return address off the stack correctly.

Michael Dunn, beat me to it. A similar problem was one of my first '  pain in the neck  ' bugs, when I was still a newbie. The sigs for message handlers have to be correct in release mode, but usually sail through in debug mode without complaint

Hi There,
Let's say I've got an MFC MDI app with three child frames open. How do I figure out which one is the active one?
Thanks,
Aaron

CFrameWnd supports a function called GetActiveView(). This should work for your purposes.

Hi All,
I'm creating a toolbar and I have a couple of questions:
1) when setting up a button on a tool bar to be multiple state (i.e. start/stop) and I want to change the bitmap displayed on the button, how do I change the bitmap on the button? And does this bitmaps need to be inserted as an icon or do they both need to be on the toolbar itself? If that is the case, would I have to make two seperate buttons and then hide the one that isn't the current state?
2) Is there a general place to find groups of generic button bitmaps or do I need to make my own?
thank you in advance. I appreciate all the help I have gotten here in the past and in the future.
Thanks.

The following code should help.. I create a function so that if a button is pressed and the bitmap needs to be changed.. change the bitmap for the whole tool bar (to either ON or OFF).. if a button is pressed and you dont need to change the bitmaps don't run the following... You get the idea..
You will need to create 2 bitmaps for the tool bar.. one for "ON" and one for "OFF".. both these bitmaps need to be in your resoruces tab..
HIMAGELIST hOld = (HIMAGELIST)::SendMessage(m_wndToolBar, TB_GETIMAGELIST, 0, 0);
ImageList_Destroy(hOld);
CImageList imageList;
CBitmap bitmap;
bitmap.LoadBitmap(IDB_OFF); <-- BITMAP IN RESOURCE
imageList.Create(16, 16, ILC_COLORDDB|ILC_MASK, 3, 1);
imageList.Add(&bitmap, RGB(255,0,255));
m_wndToolBar.SendMessage(TB_SETIMAGELIST, 0, (LPARAM)imageList.m_hImageList);
imageList.Detach();
bitmap.DeleteObject();
HIMAGELIST hOld = (HIMAGELIST)::SendMessage(m_wndToolBar, TB_GETIMAGELIST, 0, 0);
ImageList_Destroy(hOld);
CImageList imageList;
CBitmap bitmap;
bitmap.LoadBitmap(IDB_ON); <-- BITMAP IN RESOURCES
imageList.Create(16, 16, ILC_COLORDDB|ILC_MASK, 3, 1);
imageList.Add(&bitmap, RGB(255,0,255));
m_wndToolBar.SendMessage(TB_SETIMAGELIST, 0, (LPARAM)imageList.m_hImageList);
imageList.Detach();
bitmap.DeleteObject();

I'm sure you can find them some where.. I usually just make my own..

This helps.
BUT, if I have ... say ... 10 buttons that each have 2 functions to them (I don't, but just an example) I'd have to have a TON of bit maps just for that 1 tool bar. There's gotta be a more efficient way to do it. In my case this would work becuase I only have a couple of buttons, which would mean I'd have to have 4 different bitmaps I'd have to load depending on the state I'm in.
Thanks!

Yep your right.. The example I provided was based on how to change the bitmap for all buttons on the toolbar (not very usefull in your example).. I know there are articles here on codeproject and on codeguru that will show you how to do just what you are trying to do..

Ok, here comes a real hack that does work, but once implemented you will not be able to change your toolbar using the toolbar resource editor, so make sure you have all your buttons set up in their default states first.
1.) Using MSPaint (or another graphics editing tool) extend the toolbar bitmap by adding the new bitmaps you want to the end of it. remember to make all the images the same size (default is 16 x 15 pixels)
2.) to the class that will handle the button states, add an integer variable that will keep track of which bitmap is currently displayed on each button (use seperate variables or an array of them). The variable will hold the index number of the image in the bitmap. remember that the first image in the bitmap is at index 0 not 1.
3.) add an ON_COMMAND message handler for the button being clicked. in that handler, change the index variable to contain the index of the new image
4.) add an ON_UPDATE_COMMAND_UI handler for the button. here you check if the command is coming from the toolbar (as opposed to the menu), and then you use CToolBar::SetButtonInfo() to change the image.
CMyView::OnUpdateAppAbout(CCmdUI* pCmdUI)
{
if (pCmdUI->m_pOther && pCmdUI->m_pOther->IsKindOf(RUNTIME_CLASS(CToolBar)))
{
CToolBar *pTB = (CToolBar *)pCmdUI->m_pOther;
pTB->SetButtonInfo(pCmdUI->m_nIndex, pCmdUI->m_nID, TBBS_BUTTON, m_nAboutImage);
}
}
although you may want to use CToolBar::GetButtonInfo() to get the button style
