Hi all,
I'm using tooltip in an MFC ActiveX Control Project. I have added Handler for TTN_NEEDTEXT Notification Message. But this Notification is not calling. I tried in an SDI Application. It works.. Could anyone tell the solution

BEGIN_MESSAGE_MAP(CEx1Ctrl, COleControl)
//{{AFX_MSG_MAP(CEx1Ctrl)
ON_WM_MOUSEMOVE()
ON_WM_PAINT()
ON_WM_SIZE()
ON_WM_CREATE()
//}}AFX_MSG_MAP
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNeedText)

ON_OLEVERB(AFX_IDS_VERB_PROPERTIES, OnProperties)
END_MESSAGE_MAP()

regards

Rajesh

Does EnableToolTips() need to be called? Is their a group box surrounding the control?

Try this instead:

ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipNeedText)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNeedText)

How to send a message to a dialog

Nest22-Nov-04 0:15

I have a view from wh Eek! | :eek:

ere I call an Object A property dialog (modal). In that Dailog I call an Object B property dialog (non modal). It may happen that the Object A is destroyed in the Object B property dialog. So it looks logical to close the Object A property dialog automatically by sending it a message to close itself. OK, I know how to write and handle messages in general but i don't know how to send a message to the Object A property dialog.

Should i store a pointer to this dialog and then call a SendMessage? Looks absurd...
SendMessageToDescendants() called for AfxGetMainWnd() doesn't work...

Any explanation would be appreciated.

Hi,
you can define a public function in the ObjectA property Dialog and in the second dialog's close function, u just create a member of the first one and invoke the public function of ObjectA dialog box, which inturn calls the OnOK() function.

ObjectA.cpp
---------
void CADlg::Destroy()
{
OnOK();
}

ObjectB.cpp
-----------
void CBDlg::OnButton1()
{
// TODO: Add your control notification handler code here
OnOK();
CADlg *pWnd = (CADlg*)GetParent();
pWnd->Destroy();

}
or

can also use this way

void CBDlg::OnButton1()
{
// TODO: Add your control notification handler code here
OnOK();
CADlg *pWnd = (CADlg*)GetParent();
pWnd->EndDialog();

}

Regards,

Rajesh

It's not that easy - the dialog B is a modaless dialog and its parent is a MainFrame...

use GetParent() function and retrieve the pointer to the main window,
then use the PostMessage(WM_CLOSE, 0, 0);

Boy what a question, hundreds of articles have been written on this M$ spent great deal of time with iffy solutions. As for default buttons that is easy, Right Click on the Dialog in the resource view, Properties, Language.

Make sure your compiler has the targeted lang pack installed from M$.

How to resolve Regsvr32 Error?

I am having trouble in registering a dll module which is an add-in for Visual Studio .NET 2003:

DLLRegisterServer in cyclocomplexviewernet.dll failed.
Return code was: 0x80070002.

Using the Error Lookup tool this means:
The system cannot find the file specified.

My question is how do I find out how to find which file the regsvr32 program is looking for?

Try to use Denpends in Visual Studio Tools to investigate which runtime dll is needed.

Create one function called Writelog(), pass the error code to this function
and write to some file. Now check what is the root of problem !

Try to get error code using GetLastError()

nways have you written RegisterServer() function in your code of dll ?

Since FranzKlein already have the error code :"0x80070002", wots the point in using GetLastError() again ?

No, compilation runs fine. It occurs when I use Regsvr32 to register the specified dll with the registry.

Try entering the fully qualifed path to the dll in question when using RegSvr32.

e.g. Instead of RegSvr32 my.dll use RegSvr32 c:\mydlllocation\my.dll

Edit: I'm using VC6 and MFC
How do I capture the OnKeyDown() event inside an PRE element?

I have read a few articles on this subject on MSDN and here on CP but i'm still confused as to where to start.

I read that CCmdTarget is derived from IDispatch so in MFC all I have to do is derive a Event sink class from CObject and then do the typical AfxAdviseSink() or something like that.

I'm current looking at the following:

Handling HTML Element Events [^]

But i'm still lost as to where to start...

Can someone fill in the details I htink i'm missing??? Blush | :O

Thanks in advance

Cheers Smile | :)

How do I print my voice mail?
