I have a CToolbar ctrl on a CDialog. Can someone tell me how I can capture the messages for the ON_UPDATE_COMMAND_UI for the buttons on the CToolbar, so that I can then enable/diable etc?

How can i make buttons on toolbar of different sizes?
I mean, the size of first button should be different from second button on toolbar.
Is it possible?

toolbar buttons are created based on the bitmap that they show, and a regular toolbar cannot do what you want. But still there is a way of dowing it by creating custom buttons on a toolbar.

Ouch!
That will not work for a couple or reasons, but the most important reason is that they are not copying a string. They are appending a single character to the end of an existing CString. Crashing the code is not a good solution.

That should work, although I would shorten it to reply += (char)byte;
Make sure the byte you are trying to append is not zero.
Also make sure that the CString is supposed to hold 'char' and not 'wchar_t' values, although the compiler should probably warn you if that was the case.
If that fails, then try using reply.Insert(reply.GetLength(),(char)byte);
I can think of one other option, but I would not recommend it, so I will leave it there.
Good Luck!

CString is not a general-purpose data storage system. Use vector<BYTE> instead.

Hi,
I need to get deselected element of a List box.
Is there any way other than comparing the Selected elements with those of a list of previously Selected.
Any suggestions would be helpful.
Thanks

Hi! using the if(!/*appropriate selecting item function, that would be*/ GetCurSel()), a member of CListBox then do an appropriate action in the if Block. Try using the DDX mechanism.

When an item is unselected, the parent control will receive a LVN_ITEMCHANGING message.

i have 5 IP address Control in dialog.That are created at run time.then how to navigate between that.
IP address Control created using:
m_cTab.CreateIPEdit(" ", 0, 10, P_LEFT | P_TOP, 130, 0, 130);
m_cTab.CreateIPEdit(" ", 0, 11, P_LEFT | P_TOP, 130, 0, 130); Etc...

Add this in your code this will enable the tab control,
ON_WM_GETDLGCODE()
UINT Cclassname::OnGetDlgCode()
{
return CButton::OnGetDlgCode()| DLGC_WANTTAB ;
}
When the user presses TAB or SHIFT+TAB, the system first determines whether these keys are processed by the control that currently has the input focus. It sends the control a WM_GETDLGCODE message, and if the control returns DLGC_WANTTAB, the system passes the keys to the control. Otherwise, the system uses the GetNextDlgTabItem function to locate the next control that is visible, not disabled, and that has the WS_TABSTOP style. The search starts with the control currently having the input focus and proceeds in the order in which the controls were created—that is, the order in which they are defined in the dialog box template.
