Hi, I've got the following bit of code...
CString cs;
cs.Format(_T("mailto:?subject=VectorWriter files&file=\"%s\""), ftis->szSrc);
ShellExecute(lp->m_hWnd, NULL, cs, NULL, NULL, SW_SHOWNORMAL);
I want to send a file via email, "file" generates and error, does anybody know the correct switch to use?
I can't find any documentation for at all!
Many thanks,
Alan Dugdall

First of all you havent specified the email address. Then secondly, you can't send attachments this way.

It appears that mailto: does not support file attachments.
Like it or not, I'm right.

There's a MAPI wrapper here at CP that i'm particularly fond of; it does attachments nicely.

I create a MFC dialog-based application supporting automation,
add new ATL object as an interface (ITestInterface),
attempt to execute this:
CComPtr<itestinterface> pMan;
if (pMan.CoCreateInstance(__uuidof(TestInterface))!=S_OK) // fails here!
{
AfxMessageBox("Error");
return;
}
and get a failure.
Do you know what's wrong?

you should save the return code from CoCreateInstance, and use the Error Lookup utility to find out what the code means.

Right! The class was not registered.
But now i get a new instance of the application every time i use a new ptr to the interface. It acts like server and i don't see why it doesn't use itself as the server.

Not quite sure what you mean, but if you mean what I think you mean try
DECLARE_CLASSFACTORY_SINGLETON(CYourClass)
Like it or not, I'm right.

I did. Has no effect. Thanx anyway!

It sounds like it IS a server. If you want to only have one copy of the .exe running with multiple connections you have to specify it in the registration.
hRes = _Module.RegisterClassObjects(CLSCTX_LOCAL_SERVER,
/*REGCLS_MULTIPLEUSE*/REGCLS_MULTI_SEPARATE | REGCLS_SUSPENDED);
I thought REGCLS_MULTILEUSE (which is the wizards default) caused the app to be resused for each instance of its components. In fact, the correct option is REGCLS_MULTI_SEPARATE.
Good luck,
Bill

Yes, it is the server.
And no, it's not the correct option, because it keeps creating a new instance.
I think i'm gonna put the interfaces in some separated dll.
For your effort, thanx!

Probably a good idea, I don't know what else you might be doing wrong. that parameter changed fixed the problem for me. Sounds like in process components is a better architecture for what you want to do anyway.
Good Luck,
Bill

I have a situation with an edit box when the user types in an existing code, data is displayed in subsequent fields. If they type in a new number, I clear the data in the subsequent fields. The populating/clearing of the subsequent fields is triggered in the KillFocus callback of the edit box. The problem is, there are pushbuttons, like Save, Close, which now will clear the data, since moving focus out of the edit box by pressing the Close button invokes the KillFocus callback.
Is there a way in the KillFocus callback to know that a press of one of the pushbuttons is in the message queue so I can process this case differently?
Thanks in advance,
Bob

OnKillFocus provides also the CWnd to be given the focus. You can check whether this corresponds to one of your special buttons.

I tried to do this, but I don't understand what is happening. When tabbing off of the Edit box, CWnd is a value of 12b89c, CWnd hWnd is 180bd4. If I press one of the 3 pushbuttons, the values are 12b748 and 180bd4 respectively. None of these values match the CWnd value I get returned when calling GetDlgItem(PushButtonId) for each of the pushbuttons. So how do I match the CWnd value I get in the callback with the pushbuttons?
Thanks,
Bob

Oh well, I've tried in a small test app, and the CWnd passed to OnKillFocus seems to be that of the parent dialog. So I'm afraid this approach does not work. Sorry.

OK, that explains what I was seeing. Is there anyway to get the ID of the control that is about to receive focus when in the OnKillFocus?
Thanks,
Bob

Have you tried seeing what GetFocus(...) and GetNextDlgTabItem(...) return?
Also, remember that if you call any functions that return a CWnd object, like GetFocus(...), you will be getting a temporary CWnd (actually a CTempWnd) object unless you have already "bound" a class to the control in question. What that means that when in doubt, compare the value of the m_hWnd member to see if you have a certain control.
Peace!

GetFocus() does the trick, Thanks!

Use the visual dialog editor? First page of the properties dialog press the change font button?
Or use CWnd::SetFont or CWindow::SetFont

How can I use the hWnd of a property page?
I created a CPropertyPage object in a thread (using new) and then used PostMessage() in order to call AddPage(CPropertyPage) from the main app thread.
But then, I couldn't make any use of hWnd of that CPropertyPage,IsWindow(CPropertyPage->m_hWnd) returns false. PostMessage(msg,CPropertyPage->m_hWnd) and even CPropertyPage->UpdateData() fails (debug assertions).
I need to use it this way, because I just wanted to have a set of dialogs
groupped in property pages. I need to access the hWnd to use with PostMessage and WSAASyncSelect (as it will receive network notification) How can I do that? Maybe I am doing something wrong ? 
thanks for any help

OK I know why it happens... it's because MFC postpones creation of a window until it's tab is selected by a user...
Is there any possiblity to overcome that ie. to force mfc to create that window earlier and not wait for user selection ?
|

lookig into source i see something like this used in another case but maybe it is what you need
t!
BOOL bResult = CPropertySheet::OnInitDialog();
int ActPage = GetActiveIndex();
for(int i = 0; i < GetPageCount(); i++)
SetActivePage(i);
SetActivePage(ActPage); //return back
