you cannot hide/unhide teh menu item on runtime.. except if you creating menu on runtime.. you only can disable and enable the menu item

You mean something like W2A()?

knowing that he's using TCHAR string, i'd say T2A() instead

I've created a menu called Tools where in I have created a menu item called Preferences. If we click the Prefernces menu item Preferences Dialog Box will open. In that Dialog Box I have an edit box. The message entered in this edit box is displayed in the second panel of the status bar (i.e) panel no.1.
My Requirement is:
The second panel should be of a default size and it should grow according to the length of the message entered in the edit box.
How can I achieve this in MFC? Can any one help?

Use
CStatusBar::SetPaneInfo( int nIndex, UINT nID, UINT nStyle, int cxWidth );
|
|
|
|
|
you just need to do it as follows:
void CPerspectiveDoc::OnShowMsg(CCmdUI* pCmdUI)
{
CString strValue;
strValue.Format("%s", message.GetString());
pCmdUI->Enable(TRUE);
pCmdUI->SetText(strValue);
CDC* pDC = m_wndStatusBar.GetDC();
CSize mSize = pDC->GetTextExtent(strValue);
m_wndStatusBar.SetPaneInfo(1, IDS_MESSAGE, SBPS_NORMAL, mSize.cx);
}

void CPerspectiveDoc::OnShowMsg(CCmdUI* pCmdUI)
{
char str1[150];
CString strValue;
//strValue.SetLength(100);
strValue.Format("%s", message.GetString());
//sprintf(str1, "%s",message.GetString());
pCmdUI->Enable(TRUE);
pCmdUI->SetText(strValue);
CDC* pDC = m_wndStatusBar.GetDC();
CSize mSize = pDC->GetTextExtent(strValue);
m_wndStatusBar.SetPaneInfo(1, IDS_MESSAGE, SBPS_NORMAL, mSize.cx);
//m_wndStatusBar.SetPaneInfo(1, IDS_MESSAGE, SBPS_STRETCH, len);
}
When I add this code I got an exception stating ,
'Unhandled exception at 0x7c1d71bb (MFC71.dll) in Perspective.exe: 0xC0000005: Access violation writing location 0x00000014.'
When I break this exception, it ends in a class barstat.cpp which is not created by me.
Also this exception occurs only when we add the status bar variable(m_wndStatusBar) to this class CPerspectiveDoc.
The Status Bar Pane is created in some other class.
How to resolve this?
Pls help

Oh, dear friend, I think u've made a mistake! In my opinion, the CDoc class in your project is constructed before the CMainFrame class, and the status bar is created in Oncreate() function of the CMainFrame class. So, you'd used a status object before you created it. Am I right?
OK, U can resolve this by many methods.there r 2 simple resolutions follow:
1. U can do this in the CMainFrame class after the status bar object is created.
2. U can do it in the CView class as the same.

Hello,everyone! I want to ask a question about my practice. I created some string entries in the string table such as IDS_STRING1,IDS_STRING2,IDS_STRING3... .Now, I want to load one of them for the CString object by a string I specified. for example, the string I specified was "IDS_STRING1" , how can I convert "IDS_STRING1" to the right Resource ID? Thank u so much!

i'm not sure at all to understand what you want.
if i'm right, you want to get the actual string behing the string ID in the resource string table.
for this, 2 solutions :
CString::LoadString()
or
CString::Format()

Thank u for your reply, I wish u a good day!

See if this answers your question....
Answer 1:
CString Str;
Str.Format(IDS_STRING1);
Answer 2:
CString str;
if (! str.LoadString( IDS_STRING1 ))
{
AfxMessageBox("Error Loading String: IDS_STRING1");
...
}

Thank u all the same!

In additional with other members after reads Resource with CString::Load on the loop you can read all strings for example
IDS_STRING1 has "one,two,three,four,"
now on a loop set for find , in this string and reads all strings

Thanks! God will bless u.

You're welcome

There's no automatic way to do that. You'll basically need a lookup table to know that "IDS_STRING1" should be mapped to 101 or whatever the numeric value is.

use WideCharToMultiByte()

Actually, MultiByteToWideChar() is the right API. WideCharToMultiByte() goes the other way.
