If you look on www.msj.com, there was an article or two by Paul DiLascia that covered replacing views. Even if it takes a while to find, they're all really good reads, and informative.

I'm pretty sure there's an article or two on codeproject also.

Lastly, have a look to see when OnInitialUpdate is called for the first view. If it's done from the create frame code in MFC, and you're doing some mutant manual version, then the bug is *you're* not calling OnInitialUpdate.

Hi,

The OnInitialUpdate is called only when the view is created. So delete the view you want to replace and then recreate it. Now the OnInitialUpdate will work fine.

Do you mean to use OnUpdate() instead?

If it's like the code I remember, he'll be creating CTwoView, then killing COneView - and each time you create a new one, he's making sure its OnInitialUpdate member is called. Brush Pen creation etc.

I did this once, and it did not involve killing and re-creating. I created all of the views up front, and a method of my CSplitterWnd-derived class just activated the correct one, which, in turn, called that view's OnUpdate() method.

I think that depends on how many you need, and if you're switching backwards and forwards between them. You may have a large collection of choices, but only likely to use a few - in which case late creation would be best. I've used each approach on different projects.

You want to replace an existing file with a new one? If yes, show the code that you have written to do the same.

Hi,

If you are using CreateFile Function[^]Windows API to create the file, then set the 5th parameter(dwCreationDisposition) as OPEN_ALWAYS to create the new file always.

If it is some other function, there will be a flag for setting file creation mode.

Another way is to find the files by using CFileFind functions, delete them by DeleteFile() then create new files.

Post code if you have problem still.

Thanks,
Suman

Folder with same name is not possible, Do you mean, the file with same name is created like "Copy of File1" if there is "File1" already or something like that?

I need some tips on how to find out why this is happening.

I got a workerthread. And when it has added an item to an queue, I post a message to mainframe. (the message has been created with ::RegisterWindowMessage(...) )
using PostMessage( hWndMainFram, MY_MESSAGEID , 0 , 0 );

And in CMainFrame::PreTranslateMessage(...) I trap the message and I pick up the item from the queue, This all work very well. Except in one situation.

If the user are in a menu. If an menu is shown at the same time the postmessage are sent from the workerthread, The message is never recieved in CMainFrame::PreTranslateMessage(...)

Anyone got any ide on how to fix it.

Radio Button Query.

I have an MFC Dialog which houses 3 radio buttons.

I want to take some action only when user selects radio button which is not selected already so that I don't perform the same set of actions if a user RE-Selects a radio button.

Can someone advise me what's the best way to achieve this ?

Thanks
Cage

Hi,

You mean when clicking the same radio button again and again or when selecting a button and change to other again come back to previous button?

In second case, you can set a static variable like static bool bAlreadySelected = true when the button clicked already it will be true. Otherwise perform the set of options.
Set the above variable to false at startup of dialog.
This is one way. There may be some other way too.

Thanks,
Suman

No Suman, that doesnt solve my problem.

I want to take a certain action everytime the control is transferred from the other radio button, not just for the first time.

Let me be more clear. Example -

Three radio buttons be A, B and C.

I want to perform certain operations everytime user has selected A or B and then he clicks C, but I don't want to take any action if user re-selects C.

That's not very complicated: in your class declare an integer variable (e.g. m_currentSelected). On each of your radio button handler functions, assign a value to this variable (e.g. 1 for the first radio button, 2 for the second, ...).

It is easier with code:

void CMyClass::OnRadio1Clicked()
{
  if(m_currentSelected==1)
      return;

  // Do stuff....

  m_currentSelected = 1;
}
