Enabling/disabling main menu items [modified]

Using Visual 6.0 C++ MFC in SDI application

I know how to enable/disable submenu items. However, when an SDI application is created a main menu bar is created with the following:

File Edit View Help

I added an item to this list (let's call it "Test"). That menu bar looks like:

File Edit View Test Help

Under certain conditions in my program I want to disable the user from selecting "Test" and other times enable this menu item. I can't see how to do that anywhere.

Thanks for the help!

Right click on your dialog box in design mode and open its properties. Enable the "System Menu" style.

I think that you will need the border and a title bar menu. Because, by asking for a system menu, you merely are asking for the WS_SYSMENU style of the window object to be enabled. Enabling the WM_SYSMENU style will require the WS_CAPTION style to be enabled as well. The WS_CAPTION will require a title bar and a border (WS_BORDER style).

See and SetWindowLong()[^] and Window Styles[^] for details.

if ( fileDlg.DoModal() == IDOK )
{
playFile = fileDlg.GetPathName();
}

this code for me is working nice but an instance of the same application is created in the taskbar with the just an small icon and no default right click menu when the filedialog popsup .Why its so???, my app is vc6 dialog based app.

unsigned char* to const char*

Why do you need this conversion? What are you trying to achieve? I am asking this because the 'const'ness would matter much, only if you are trying to cast the const away. Are you trying to pass an unsigned char* to a function that expects a const char*? There's no harm in that case, because you are merely providing a modifiable value to a function which promisingly will not modify the value given to it. You also need to know the possible loss of data that might occur while converting between signed and unsigned datatypes.

First of all I agree with Rajesh. What is your point in C++ in this question.
Secondly, I guess your question is beyond programming so I'm saying "don't bother, use tools like NetLimiter"

Toolbars in VC++

Vilas Tamhane30-May-08 23:22

30-May-08 23:22

All my hidden toolbars are docked, if one is already docked, after the commands Print or Print Preview
Project MFC AppWizard(exe)
16 toolbars are created in the main frame, with code as follows,

if (!m_wndStiffenerBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | NULL | CBRS_TOP| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||!m_wndStiffenerBar.LoadToolBar(IDR_STIFFENER))
{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}

m_wndStiffenerBar.EnableDocking(CBRS_ALIGN_ANY);

EnableDocking(CBRS_ALIGN_ANY);

DockControlBar(&m_wndStiffenerBar);
Like this toolbar, as shown above, all are initially hiddens
//Toolbars can be docked with menu command, as follows

void CMainFrame::OnMoveStiffener()
{
// TODO: Add your command handler code here
BOOL bVisible;
bVisible=((m_wndStiffenerBar.GetStyle() & WS_VISIBLE)!=0);
ShowControlBar(&m_wndStiffenerBar,!bVisible,FALSE);
RecalcLayout();

}

void CMainFrame::OnUpdateMoveStiffener(CCmdUI* pCmdUI)
{
// TODO: Add your command update UI handler code here
pCmdUI->SetCheck(((m_wndStiffenerBar.GetStyle() & WS_VISIBLE)!=0));

}
The code is standard and works well but if a single toolbar is docked and if I give Print preview command, all the 16 toolbars, which I have created with similar code as above, are docked one below the other. If I hide all toolbar then this does not happen with Print command.
I will be grateful if you can help.

Hi,
I am using a radio button of type int.
If it is type int how can I disable/enable and hide it.
If it is of CButton I can enable and disable it using GetDlgItem().EnableWindow.
I dont know how to do if it is of int type.

Thanks.

Regards,
Sunil Kumar

You can disable radio buttons too by GetDlgItem().EnableWindow(). For instance,

// Disable Radio button.
GetDlgItem( IDC_RADIO1 )->EnableWindow( FALSE );

Jijo.
