From MSDN page for WM_ACTIVATETOPLEVEL
http://msdn.microsoft.com/en-us/library/xkd95027(VS.80).aspx[^]
I got the below description:
This message is similar in use to WM_ACTIVATEAPP, but works in situations where windows belonging to different processes are mixed in a single window hierarchy (common in OLE applications).
Does anybody know where is a example/demo available that illustrate "windows belonging to different processes are mixed in a single window hierarchy"?
I googled but found almost nothing.
Thanks!

I would assume that this will happen when (say) Word runs its windows inside your application to deal with an embedded object?
So would apply to the windows / processes associated with any OLE object.

Hi All!
I am developing an OLE Object for MS-WORD. Now I meet a problem. And I hope someone can help me.
The Object I developing can be added into a .doc file. After added, it will draw a shape such as rectangle or circle etc. as the proof of existence. Now I find that when the .doc file which had been added the Object is to be loaded, the shape will be drawn twice. And the position of these shapes are different. I don't know why this occurred.
During the time I try to fix it, I noticed that the call of "CComControlBase::InPlaceActivate" is very important. Only after I call it, the loaded object can work. I think this means that one of the two shapes I see is owned by "InPlaceActivate". The other is owned of "UIActivate". But I can't find anyway to make this object is "InPlaceActivated" or "UIActivated" only.
Is there anyone could be kind to tell me the correct way to fix this problem? Thank you!
Best regards!

Hey guys,
I have been writing Windows apps with WTL for years but now for several years it hasn't been updated and the new Windows versions are coming out with more controls and messages and none of them are supported by WTL. What now?
Sincerely,

Hi all!
Now I am developing an application which will use many technology about OLE. But I know little about it. I often meet the problems. When I seek the answer in MSDN, I notice that a document named 'OLE specification' is often be referenced. I try to find it. But nothing can be found through google. Is here somebody know it? If somebody know, I hope you could be kind to tell me the web-link of it, or send it to me by email. Thank you!
Best regards!

Question 1:
I create one CDockablePane wnd and dock it in the bottom of the parent wnd. But the default CDockablePane height is too short and I want to resize the height of the CDP. But don't find any workable method to do.
Btw, if the CDP is docked in the left/right side of the parent wnd, it works well when setting new width.
Question 2:
Another question is how to make the CDP floating when initialized. The CDP is initially docked in one side when created. But I want to make it floating after it is created in the target position and with a initial size. How to do it ?
I feel very hard to control the CDP programmatically, like floating, resizing and moving with MFC. I found one artical from MS website about docking window management programmatically. But it is for C# Winform, not for MFC.
Can anyone give help?

I have the following piece of code which returns the handle to the window which should receive the focus,
CWnd* pWndNewFocus = GetNextTabStopWnd(pWndCurrentFocus->;GetSafeHwnd(), iDirection);
For setting the focus to the new window, i've written the following code, pWndNewFocus->SetFocus();
Incidentally the window that is set to receive the focus is a CButton. I have an OK button which is default button and a Cancel button. OK button is dithered. So the pWndNewFocus will be my Cancel button. When SetFocus is getting called on that, i'm not able to see the focus [dotten line around the caption] on the button.
Could you let me know the reason for this error? The same code when I execute it from VC++ 6.0, the focus is correctly getting set to the button. But when i execute the code in VC++ 10, i'm getting this issue.

Hi All,
I am working on a dialog which have several controls and an Ultimate Grid
(UG is invoked from OnInitDialog m_TestGrid.AttachGrid(this, IDC_STATIC);).
When i use the "Test Dialog", The tabstops work as i defined.
But when i compile the code and run the dialog, Tab Stops dont work.
The tabstop works only when i switch between 2 controls(Ex: stop 7 and 8).
Can anyone give me some inputs on this.

Hi,
I am having the follwoing CString "0000122334" and I need to remove the starting zeros from the string.
Kindly help.
Thanks in Advance.

Probably something like this[^].
The best things in life are not things.
|

|
|
|
Use The method CString::Remove like thish
CString TempString("0000122334");
TempString.Remove('0');
|
|
|
|
|
Try using CString::TrimLeft() to remove leading characters (see documentation in MSDN), CString::Remove() will remove all instances and not just the leading zeros.
|
|
|
|
|
here there are two method.
method 1: if your string is numeric then first convert into integer and again change into string.
eg. CString cs("000012345745");
int num = atoi(cs);
cs.Format("%d",num);
method 2:
eg. CString cs("000012345745");
cs.Trim();
int start=0;
while(cs.Mid(start,1)=="0")
{
start++;
}
cs= cs.Mid(start);

My MSAA Hook dll is expected to be loaded into all process's memory. in 32 bits Win7 it works.
But in win7 64 bits some process can load MSAAHook.dll 64 bits cannot be loaded into some 64 bits process. Why does this happens?
= ::SetWinEventHook(EVENT_MIN,
EVENT_MAX,
m_hModule,
MSAAHook::WinEventProc,
0,
0,
WINEVENT_INCONTEXT | WINEVENT_SKIPOWNTHREAD);

Currently, "exiting" (pressing upper right-hand corner's "X") WMP closes the WMP window but allows WMP sound to continue. How can this WMP "exiting\termination" event be caught or trapped programmatically so as to enable clean and thorough shutdown of Windows Media Player? Can the WMP ATL's OnOpenStateChange possess a Dispatch Identifier (known as DISP) that can catch this closure and termination event?
Thank you.

I converted old C++ project to VS.Net 2010 with 4.0 Framework.
error C2440: 'static_cast' : cannot convert from 'void (__thiscall CChatView::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'
ON_MESSAGE(WM_ChatAddSize, OnChatAddSize)
void CChatView::OnChatAddSize(LPARAM lParam, WPARAM wParam)
afx_msg void OnChatAddSize(LPARAM lParam, WPARAM wParam);
Help would be really appreciated.
Thanks

You have your WPARAM and LPARAM in the wrong order, and your return types don't match; read the error message, it contains pearls of wisdom.

that's right, they are not related pointer type.
