The easiest way is to put that stuff into the CYourApp::InitInstance

A good place to insert this is in your CWinApp-based InitInstance, just before anything else. If the login fails, just return FALSE.

we have a login screen just as you describe
at the end of InitInstance() we post a message to ourselves mimicking the 'log on' toolbar button
the logon box pops up very nicely 
situations to avoid #37:
"good morning ... how many sugars do you take in your coffee ... and what was your name again?"
coming soon: situations to avoid #38: "...and the dog was there too?"

Thank you everyone... putting the doModal( ) into the InitInstance function worked perfectly

I need to change the background color of an OCX composite control at a regular basis. When I do this the composite control and all controls within are redraw. This causes the application to flicker. Can this somehow be prevented?
|
|
|
|

Can you modify the source code of the OCX? If so, consider using double-buffering when painting. Check Keith Rule's Flicker Free Drawing In MFC.

Thanx for yor reply. I can modify the OCX code, however my OCX is a composite control and it seems that the OnDraw is never called, instead the CAXWindowHost::OnPaint. Overloading this call seems tricky, do you know how I can trigger the OnDraw of the composite control?

Hi,
I have written a small application using DirectShow that plays an MPEG or AVI movie in full screen mode. My code is based on the "playit" sample code that comes with the DirectX SDK (or at least it came with 6.1), and it uses WinAPI. All I want to do is have it so that the movie finishes (exits) as soon as you press any key on the keyboard (or one of the mouse keys, though that's not as vital). This is probably a very dumb question (I am very new to DirectX and not a very experienced programmer in general), but how can I do this? I *think* that I somehow need to send the message EC_USERABORT to the movie window as soon as the user presses a key. I have tried using put_MessageDrain() and so on, but it doesn't seem to recognise my window - or at least, it doesn't work.
This is the main loop of the PlayMovie() function:
long evCode, param1, param2;
bool bcomplete=false;
while (hr = pME->GetEvent(&evCode, ¶m1, ¶m2, INFINITE), SUCCEEDED(hr))
{
switch(evCode)
{
case EC_USERABORT:
bcomplete=true;
break;
case EC_COMPLETE:
bcomplete=true;
break;
}
hr = pME->FreeEventParams(evCode, param1, param2);
if(bcomplete==true){break;}
}
If anybody could tell me how to get my movie to close as soon as the user hits any key, I would be very grateful.
Many thanks for any help,
KB
P.S. Apologies - I posted a similar message a few days ago; however, I am still stuck and my old post seems to have been lost pages back...

How do I set the mouse position (in absolute coordinates) in Win32?
Thanks.

Use this function:
BOOL SetCursorPos(
int X,
int Y
);

Thanks! I forgot the function name and I'd hate to look through MSDN.

I think that looking through MSDN is a skill that you become good at only after years of practice and experience.

The good thing though is that it will take years to complete your first search, so by the second one you'd be an expert...

SetCursorPos(x, y) where x and y are screen coordinates.
If you have client coordinates or coordinates relatives to another window, then you can uses function like MapWindowPoints or ClientToScreen to do the proper conversion.

Hi, could anyone give me an answer to this.
We have a long operation involving that we have wrapped with a CWaitCursor. However, during the processing, the cursor flickers back and forward to the pointer.
Any ideas what we can do to keep the hourglass visible?
Cheers,
Steve.
if(E_NOINTERFACE == pThat->QueryInterface(IID_IUnknown,(void**)&pUnk))
{
// I aint no pUnk bitch!
}
|
|
|
|
|
Whenever you window need redraw, the cursor is updated. If you want to stick to your CWaitCursor, you need to overwrite SetCursor().
|
|
|
|
|
Ahhhh,
documentation.
Maybe I should have read it in the first place.
Thanx for your help.
Steve.

I think it's simpler to just do:
AfxGetApp()->DoWaitCursor(1);
doSomething();
AfxGetApp()->DoWaitCursor(-1); /ravi

If fact, temporary cursor are restored as soon as the mouse is moved (see SetCursor doc) and in pratice, it means that the cursor will be restored if windows messages are processed which may be the case if something with a message loop is called (COM apartment switching, message box,...).
The only way to ensure that the wait cursor stay displayed is by calling something that will do a permanent change of the cursor (or also by processing WM_SETCURSOR) or by associating a NULL cursor with your window.
In MSDN documentation, it is said that the cursor must be restored if an operation cause the cursor to be changed (see CWaitCursor::Restore).

Hi guys n gals, how do i disable a push button at runtime?? Is there a function in CButton class to disable a button? I couldnt find one.
thx
bye
|
|
|
|
|
Use EnableWindow(FALSE) for the buttons you want to disable.
for example, you have a push button with a control member variable m_ctlButton associated with it. So
m_ctlButton.EnableWindow(FALSE);
|
|
|
|
|
All CWnd derived class's have the EnableWindow(true/false) function
Also take a look at the CWnd class member functions to see what may also be applicable to your button or other window types.

Question: What is the maximum # of variables you like to pass into a function before you decide it needs redesigning to use a struct or some other method?
I have an old math library, some functions take 10 parameters.
Just curious if there was any "common-sense" standard.
(I have no common-sense, so I have to ask....)
