Hi,
I have a dialog based application, in which when the user clicks a particular button, a time consuming process gets executed. Till the process completes, the user should not be allowed to operate any other button on the dialog.
Step 1
So, in the handle for the button click I add code like:
OnButton()
{
CWaitCursor myCursor;
//Long processing
}
But now, if the application is minimized, it cannot be seen again, ie the dialog becomes completely unresponsive.
Step2
So I created a thread to do the long processing. But the problem is I have to wait for the thread to finish before exiting the button handle...
Step 3
Then to be able to process message, after the AfxBeginThread, I added a message loop. Now the final code looks like:
OnButton()
{
AfxBegindThread()
while( WaitForSingleObjecT(handle, 2) = timeout || getmessage())
{
dispatchmessage()
}
}
But still this does not seem to work. Can any one help me with this?
Thanks !

Anyone figure out how to get the movie rect for an ActiveMovie4 window?

In my initialupdate in the view I have this:
m_editright.SetSel(-1,1);
THe first thing that happens is that I see the gui, with the selection unmarked as I want. Then a Open File dialog box pops up
Just before SetSEl is a postmessage that brings up a dlg box (Open CFileDialog)). If I cancel this,the box goes away but the selection gets marked again. Why does this happen? How do I get around it? the setsel happens last in my oninitialupdate, right after PostMessage.
Thanks,
ns

Its a side effect of the control having SetFocus() after the open dialog is dismissed called on it.

Is this okay? I dont need to tab to this box so I unchecked tabstop in the designtime properties, and the focus never gets there now. It was the last ctrl on the form so I wonder where the focus is since I forced it not be be on my last ctrl. Is it possible for no control to have focus? SOmething must have the focus!
thanks,
ns

When you layout a dialog box in the resource editor, you should really set the tab order for the controls. You can do this by hitting Ctrl+D. You then click on the controls of the form in the order you would want the focus to move.
Your CEdit control was probably getting the focus because is was probably the first control you added to the form.
You should always set the tab order for controls on a dialog so that the sequence makes scence to the user.
Use Ctrl+T to test the dialog.

Hello
I am looking for a PDF generation control that is not dependent on Adobe distiller or Adobe PDFWriter. The control should be standalone and should be able to create PDF files with text, images etc.
It should be able to handle multiple threads at the same time, where two or more clients might use the control to generate a PDF at the same time.
Commercial or Shareware - no problem! Even cost is not an issue.
I did some searching, but I want the best! And if someone who has used a similar control in the past can give any suggestions, I'd be extremely grateful!
Regards,
Nish

Look at GhostScript - but it is not a control and it is non trivial to use - don't know if its what you want

My application must store some data on a CD-ROM.
I have installed EASY CD CREATOR in order to user DIRECT-CD.
In this way I can easily use the CopyFile function to solve my problem.
This operation work without problems but when the CopyFile function returns,
the CD-ROM Writer hasn't already finished to write data on CD (it has to perform the final write operations).
How can I determinate the real end of the copy operation in order to show
a meaningful progress bar ???
Thank you very much!!

If you're on XP, there's a nice new interface
called IMAPI that allows good control of the

Hi there,
How do I draw a rectangle around my CMainFrame derived class?
My SDI application has **multiple** mainframe derived class. When I switch between them, I want to draw a rectangle around the frame which is currently active.
Thankx very much

Although i couldnt draw a rectangle around the "frame", i could draw one around the client area, by the following code in the view's OnDraw:
CRect rect;
GetClientRect(rect);
pDC->Draw3dRect(rect, RGB(255, 0, 0), RGB(255, 0, 0));
But... fi I resize the window a few times, maximize minimize etc.. the effect is bizarre. Please help.. I think its also making my system sluggish. GDI Gurus!! Pls help

I haven't tested your code, but I suspect the 'bizarre' effect is that the rectangle is not being erased. Override the WM_ERASEBKGND message to clear your background.

Hello,
I am getting the strangest error. I have a VC++ application using VC++ 6.0. At one point in my application, if I press "Enter" the application just quits. If I press anything else of click the button to go on a next screen etc. .. it works fine. IF I press the "X" on top corner to quit, it asks me if I want to quit and quits normally. But if I press Enter on that screen it just suddenly terminates, completely blimps out!!
In Debugger, It goes into Wincore.cpp. For some reason ContinueModal() ends up returning "0" at the last minute. Until the point it calls it .. when I look at it in the Watch ContinueModal() is NonZero. But inside ContinueModal() looks like one of the pointers (WF_CONTINUEMODAL) is null.
I will really appreciate any help on insight into this. Thank you very much !
Sincerely,
Anjum Gupta.

If it is a dialog application, it might be the dialogs default OnOk() that causes this. If so, override it and remove the call to CDialog::OnOK().

Could anybody suggest a good ATL book? I've found a few, and they all have pretty widely ranging reviews on Amazon, so I thought I'd ask here
ATL COM Programmer's Reference, by R. Grimes (Wrox)
Creating Lightweight Components with ATL Book/CD Package, by J. Bates (Sams)
Professional ATL COM Programming, by R. Grimes (Wrox)
Developer's Workshop to COM & ATL 3.0 Book/CD Package, by A. Troelson (Wordware
Publishing Inc.)
I thought I'd qualify the question a little more -- I'd like to develop a few Office Add-ins using COM (and thus would quite like to stick with C++ rather than going with VB), and with the possibility of also doing one or two COM components for use in ASP applications. Finally, I'd also like to produce a data access layer for a desktop app that will store data in an MSDE database. The main MFC desktop app will retrieve data via. this COM component, and the Office add-ins will also interact with the DB via. the COM component.
I've touched ATL only briefly before, mainly as a result of the Programming Visual C++ book by Kruglinski et. al., and want something a little more in-depth.
Thanks,
Paul

Had the beginning one and it was too hard, so I imagine this one is completely not for beginners.
