Hi !!!

In my MDI App, if the user close a child window (derived from CFormView)by clicking on the top right cross button (X), I would like my program to ask him if he is sure or not.

How could I do that ? Which message do I have to intercept ???

Thanks for your help !!!

Jed

Read the docs on CDocument::CanCloseFrame() That looks like it'll suit your needs.

Hi, everyone.
When I want to write some classes to display a menubar like VC IDE, I encountered a problem about drawing system items, the three buttons ,icon and system menu which is originally on the child window caption bar.When the child window is maximized, I have to draw them on my menubar, the icon and menu is easy to draw, but how about the three buttons on right. Is there some effient ways to do these jobs?
Thanks in Advance!

The API to do this is DrawFrameControl().

i'm looking to find an HWND for a stationary Dialog box
this is what SPY++ gives me

WINDOW: 000004AC
TEXT: ""
CLASS: #32770(Dialog)
STYLE: 50000044
RECT: 6,380)-(598,524) 592x144
THREAD ID: FFFCB805
PROCESS ID: FFFCBFC9

is there anyway i can find the HWND or a CWnd to this dialog box, and veryify it with this
or any way i can get the mainwindow, and follow through, to this dialog?
it doesnt matter if its MFC or winAPI
Just need a way to get to this HWND
any help would be great
regards!

The Window line (WINDOW:000004AC) is the HWND of the Dialog.
HTH,

I have seen several apps on Win98 that use softshape's
ActiveSkin ActiveX control. Mostly this control allows people
to haev a coherent means for creating skinned 'applications'. It includes
one function that allows you to set a transparency level.
If you download the control right from softshape you can use the
Visual Studio tools to view the interfaces their control provides.
There is an app called BoxCard @ http://softini.cjb.net
that uses this feature and will let you see it in action

I've tried several things briefly to try and implement some transluceny. It
is pretty easy to make a translucent menu or
dialog as long as it is WITHIN a frame window or something. You can
just make owner draw controls that get the parentdc and alphablend the
control DC with the parents. This works really well if you have a
stable bitmap background. However, this become very hard to do when you
have other windows moving around behind a translucent control or
you try to do this on the windows desktop.

Win2K provides a LayeredWindow to help with this. Does anyone have access to
a W2K dev kit that contains this implementation? I check my VC 6 for this
but it does not seem to be included. I'd like to see how they did this.

I also considered it might be possible to control how windows draws the
window, after all - doing this can't befar off from what programs like eFX
and WindowBlinds have been doing to change the frame bars on existing
windows already.

Any suggestions? I plan on putting all this info together with some other
controls I've made and putting it up on the web with source. MFc is nice,
but its really easy to think of semi-simple things that are very diffculut
to do - like change an image on a static control (w/o hiding an existing one
and displaying a new control) Anyways, I'm getting off on a tangent. Please
let me know you thoughts or tips.

I have CWnd* wnd;
And I have CDC* pDC;

How can I draw wnd to pDC?

Have you tried using CWnd::OnDraw(CDC *pDC)?

I've been developing an MFC regular dll which exports a function which creates and displays a dialog. Everytthing works fine. However I get a problem when I
insert an Active -X control (eg: MS-Chart control) at design time and then display the dialog. In this case when I call my exported function the dialog is not displayed at all, and I noticed one thing DoModal returns IDCANCEL.
What do I do to solve this problem.
Thanks, Anyhelp would be highly appreciated.

Did you call AfxOleInit() and AfxEnableControlContainer() ?

Actually the client part of the code creates an MFC worker thread which calls my exportred function.
I found a KB article in MSDN which said that I need to call OleInitialize(0) from my client. I did that also, but the dialog is still not displayed. Any ideas ?

Here is the pseudo-code,

UINT Thread Proc(LPVOID )
{
//exported function from regular dll which
//has a dialog with a Registered Active-X control
ShowDlg();

return 0;
}

void CMainFrame::OnViewTest()
{

AfxBeginThread(x,y);

}

The thing works fine if there is no thread involved.

Anyone written a custom button that looks like the "Open" button in the common file open dialog in Word2000? On the right of the button is an arrow that when pressed brings up a menu, however when any other part of the button is pressed the button asks normally.

Thanks

Hi all,

is it possible in c/c++ to call a function that is created from variables. ..

ex/
CString myFunction

myFunction = "SomeFunction()";

i would like to call the contents of myFunction.
don't know if its possible, any insight appreciated

Brain

Possible? Sort of kind of - check out Pete Becker's reply to a similar question at:

Brian:

Yes, this is possible.

The function GetGreater will get the greater of the two values passed in...

int GetGreater ( int, int ) ;
typedef int (*GetGreater) (int, int) ; // this declares a ptr to this function.

Then in the code...

{
PGetGreater pgg;
int maxvalue;

pgg = GetGreater;
if ( pgg )
{
maxvalue = pgg ( 5, 3 ) ;
}
}

Or something like that Smile | :)

Hi, I use contiguous range of command IDs and ON_COMMAND_RANGE() in my app. However, the IDs always be renumbered when I add other resource. This phenomenon drives my crazy. I¡¯d appreciate if someone could tell me how to prevent the renumbering. TIA.

I have a mapi session (logged on using and existing session), and as such, I have not specified the profile name.

Now that I am logged on, I need to know the name of the profile currently in use.

Any help out there?

Does anyone have any sample code (or know where some is) to put a tab control on a toolbar. Like the ones in 3D Studio Max, or C++ Builder?

Or, does the article here about adding controls to toolbars work?

Thanks,
Frank

I have used the class wizard to generate a wrapper class from the type library
of an in process server.

I can access the methods and properties by creating a dispatch like this one for both.

if(((*(COleDispatchDriver*)(&m_IMCSClientEvents))).m_lpDispatch==NULL){ //UCS_MCSSERVER.EXE
if (!(m_IMCSClientEvents.CreateDispatch("MCSObject.MCSObject.1", &oe))) {

But how do I capture the events. Do you create a dispatch for events? If so how do you capture them? I'm confused.

I suspect the answer is use the EVENTSINK_MAP. But that would require an IDC value. Since I am late binding
I do not have an IDC value I am not sure how to use the EVENTSINK_MAP.

Thanks in advance.

Hi!

As you've already mentioned you can't use the event map in the late binding. You have to implement the event sink and then use one of the functions below to create a connection between an object's connection point and a client's sink:

CComPtr::Advise(...) - using smart pointers

AtlAdvise(...) - using ATL

IConnectionPoint::Advise(...) - generic interface method

And of course you have to Unadvise when you are done with the object.
