Hi all,

I have problem related to speed (alt) keys in PropertySheet.
I have overridden the OnWizardFinish() method of a CPropertySheet
derived class. I have edit box on PropertySheet. If i enter something invalid or keep the edit box empty, and click Finish button, an error message will be displayed. When i click OK button of error messagebox, the focus is not set on the edit box (Even though i have used SetFocus after MessageBox)and moreover alt keys will not work.

What may be the problem? Thanks in advance.

Can you tell: Are you using AfxMessageBox() to display the error message?

Try passing the handle of the window to the message box function eg: MessageBox(myDlghWnd,...);
if you are passing NULL and then try and setting the focus. I faced a similar problem and resolved it but just can't recollect it for now.

I am using VC++ 2005.
As i said i was using

MessageBox(LPCTSTR lpszText,
                                LPCTSTR lpszCaption = NULL,
                                UINT nType = MB_OK);

MessageBox what u suggested was

::MessageBox(HWND hWnd,
             LPCTSTR lpszText,
             LPCTSTR lpszCaption,
             UINT nType);

I used what u said, alt-keys working. But it's not displaying MessageBox.

Anyways Thank you very much.

Does the message box pop up behind your application or somewhere else?One good option would be to debug the code and check if you see the message box or where is the control at that time when you invoke the msg box.

why you have to call the method, the framework will send appropriate message. You have to handle those messages, thats it..

That is, add a message map entry, the macro for button click notification is,

ON_BN_CLICKED(id, mesasgehandler)

Pressing Enter Key will lead to call CDialog::OnOk method.. so override the method and don't call the base class implementation, instead call which ever function you want. Also pressing Esc key will call CDialog::OnCancel method...

Both OnOK and OnCancel will close the dialog, but the return value will be differnt is the dialog is showed using DoModal method..

Use OnUpdateCmdUI, and enable or disable menu item conditionally.

Hi All,
I want to examine whether a node in the tree control is presently expanded or not (i.e. it has the '-' sign infront of its label.
I cannot do it with GetItemState(hItem,TVIS_EXPANDED).
The problem is that the return value of GetItemState is the combination of the flags TVIS_EXPANDEDONCE and TVIS_EXPANDED.
How can I test for ONLY TVIS_EXPANDED?

Thanks in Advance.

Did you tried like..

if( TVIS_EXPANDED == GetItemState(hItem,TVIF_STATE)&TVIS_EXPANDED)<br />
{<br />
      // items is expanded.<br />
}

UINT nState = GetItemState(hItem, TVIS_EXPANDED);<br />
if(nState & TVIS_EXPANDED)<br />
{<br />
 //Add the Expanded bitmap for the Tree Node<br />
}<br />
else<br />
{<br />
 //Add the Expanded bitmap for the tree Node<br />
}

the above code is working fine in all cases.
When there are some child items under a node.It is showing the Expanded bitmap.
But whenever i delete all the child nodes, i am expecting code in the else to be executed.

But it is not happening.
How is this possible ??
Thanks guys for u r response.
Naveen your code also is not working.
