I wrote a class CCamCtrl. I use a Custom message WM_CAPTURE_IMAGE and used message mapping. A dll is to post message. I think dll does not post messsage, sothat OnCaptureData(WPARAM wParam, LPARAM lParam ) event can't be called.

Are there any problem in my code or in dll.

here i mention that dll works well for dialog based application.
Can anyone help me?

Thanks in Advance
Mazhar

header file
class CCamCtrl : public COleControl
{
//some code
///
///

// Message maps
//{{AFX_MSG(CCamCtrl)
afx_msg void OnCaptureData(WPARAM wParam, LPARAM lParam );
afx_msg void OnShowWindow(BOOL bShow, UINT nStatus);
afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
afx_msg void OnTimer(UINT nIDEvent);
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

in cpp i wrote
BEGIN_MESSAGE_MAP(CCamCtrl, COleControl)
//{{AFX_MSG_MAP(CCamCtrl)
ON_MESSAGE(WM_CAPTURE_IMAGE,OnCaptureData)
ON_WM_SHOWWINDOW()
ON_WM_LBUTTONDOWN()
ON_WM_TIMER()
//}}AFX_MSG_MAP

ON_MESSAGE(OCM_COMMAND, OnOcmCommand)
ON_OLEVERB(AFX_IDS_VERB_PROPERTIES, OnProperties)

END_MESSAGE_MAP()

Hi all,

I would like to know in general what causes a large amount of virtual memory to be used when creating an application. I.E What within the application causes a large amount of virtual memory to be used.

Thanks in advance

If you create a lot of classes with'in huge memory allocation. And you don't release it.
Or if bitmaps are loaded.

I sawed already that the visual studio debugger don't frees the memory at realtime.
If you create a view, close it, create, close, ...
then you get not the initial memory size of your application

I think it's not necessary.
The sample code in CDocument::AddView has already given a better way, also an MFC way, and more general. It applies to CView CFormView etc.

And... the relevance of this message is.... ?????

If it is related with your old post... why the hell didn't you make what toxxct recommended you?

And BTW... I used the MSDN article as well to make my multiple views... and it didn't work right just with that they explain. If there has been no updates since then... you will have some problems.

If the article is not good, it will wastes developer's time potentially.
If it is right, I'd like to learn about it.

I have already answered that more than once, but as now (at least for me) the perma link are not working, you should use the search by yourself.

Use "CFormView" and my nick in the options. The messages are quite old. I answered in three main points (different messages) How to add a view (2x) and how to close a view(1x)

Check msdn for CDocument::AddView

There is a piece of sample code, it is enough to do the work. I've just used it in my project, One doc with three formviews, very well.

And why are you announcing that here? Do you think we have control over MSDN content? If something is indeed wrong, let MSDN know, not us. Roll eyes | :rolleyes:

No. In MS Office Word - the standard toolbar having "Font Color" button. Whenever we change the color from the Color Palette, the color is being updated as small bar(rectangle) at the bottom of the "Font Color" toolbar icon. We need to implement similiar sort of button.

Thank u very much

Could you be more descriptive? Like giving us information on to what the application is. Giving parts of the code which generates the error. Otherwise you are leaving us in the dark here.

My guess: you have your own custom version of CDialog (that has nothing to do with MFC's one) and you're calling the method OnOk it hasn't.
