Hi,
I am using ON_COMMAND_RANGE_HANDLER(ID_FIRST,ID_LAST,Onmenuitemselected)
The problem is When the user logs in as admin all the menu items are displayed and hence proper menu id gets invked.
If the user logs in to the application as operator, he does not have proper privileges , hence some of the menu items will not be displayed.
At this time, when the user clicks , third item in the menu (ID_FOURTH),ID_THIRD gets passed as wid.
Is there any way to handle this?
Regards,
Anitha

Menu IDs should stay the same whether the option itself is displayed or not.

It does not when he assembles the menu entirely "by hand".

Why would that make any difference? Whether the menu is "designed" at design time or at run time, the IDs should all be known ahead of time.

No, Menu id's are same they r defined in header file like
ID_FIRST 2001
ID_SECOND 2002
But when some menu items are not displayed, the ON_COMMAND_RANGE_HANDLER takes the menu items in sequence.hence , wrong functionality gets invoked.

If ON_COMMAND_RANGE_HANDLER() (which I was not able to find on MSDN or Google) is not working, try using:
ON_COMMAND(ID_FIRST, Onmenuitemselected)
ON_COMMAND(ID_SECOND, Onmenuitemselected)

You are probably better off when you use a menu resource with the maximum of entries and then disable/hide some depending in the OnUpdate...() handler, depending on the application state.

Hi. I have a CTreeCtrl menu, and every once and a while I refresh the tree by calling DeleteAllItems() then re-adding all nodes. How can I prevent display updates of the the control until all items are added? Right now when the tree is refilled, you can see it all being deleted then filled up. All happens in a flash, but you can still see it refresh and I'd like to get rid of that if possible. Thanks!

Use the SetRedraw() method.

Thanks! I knew it was something simple, I just couldn't find the method.

class A {};
class B { public: B (A a) {} };
int main()
{
A a;
B b=a;// this statement gives no error! How? please explain
}

Because this statement calls the constructor directly, it's equivalent to...
B b(a);

Have you set a breakpoint in B's constructor?

I haven't used any of the VC++ 2008 betas, but the addition of multi-threaded compilation and improved debugging for multi-threaded programs has me interested. I currently use Visual Studio 2005 Standard (with SP1 and Intellisense hotfix), but am considering downloading the free VC++ 2008 Express, and then just copying all the files/folders from the VC\bin folder to the VC 2005 program folder.
I'm also having problems with the Document Explorer from VS2005 crashing consistently on XP x64 SP2, so am also downloading the VS2008 MSDN beta, hoping this will fix my problems.
For completeness, I'll also probably download the latest Platform SDK (as I'm still using the VS2005 one).
Has anyone else tried this ?
Is VC++ 2008 suitable for production code ?
Is it as easy as I make out ?

In what circumstances dynamic_cast is used?

I have a small doubt on edit box. i am making a dialog based application. i have three edit boxes in the screen.
1.want to know how to set a range(eg 1-10) if i enter 11 it should pop a message.
2.i want to set the final value of the first edit box as the minimum value of the third edit box and the final value of the second edit box as the final value of the third edit box.
hope the query is understood.

to restrict an edit to a given range, you could attach it a spin control.
for the second point, where are you stuck ? getting/setting an editbox value ? or the calculation behind that ?

extremely sorry for again putting the query in the forum.. well i wanted to know how to set the third edit box value.

no problem mate

like this for instance:
CEdit* pEdit = (CEdit)GetDlgItem(IDC_MY_EDIT);
pEdit->SetWindowText(_T("Hello World"));
|
|
|
|

this i am aware..
take for example.
my first edit box minimum range is "1" and maximum range is "10". and the second edit box the mininum range is "1" and the maximum range is "20". i want "10" to be the minumum range of the third edit box and 20 to be the maximum range of the third edit box.
hope its clear.

In this case, I would make a function validating every editbox content. And if all are ok, then return true.
If you have lot of EditBoxes (I have one dialog with 24 coloured comboboxes), you can make it dinamically. I put the example to NUM_EDITS different editboxes.
CEdit* m_aPEdits [NUM_EDITS];
.
void CMyEdit::OnInitDialog ()
{
m_aPEDits [0] = (CEdit*) GetDlgItem(IDC_MY_EDIT1);
m_aPEDits [1] = (CEdit*) GetDlgItem(IDC_MY_EDIT2);
m_aPEDits [2] = (CEdit*) GetDlgItem(IDC_MY_EDIT3);
m_aPEDits [3] = (CEdit*) GetDlgItem(IDC_MY_EDIT4);
}
BOOL CMyEdit::ValidateEditContents ()
{
int nError = 0;
for (int i = 0; i < NUM_EDITS; i++)
{ int nTemp = -1;
nTemp = itoa (m_aPEdits[i]->GetDialogText ());
if ( ((10 * i) < nTemp) && (nTemp < (10 * (i+1))) )
continue;
nError++;
}
if (!nError)
return TRUE;
return FALSE;
}
void CMyEdit::OnOK ()
{
if (ValidateEditContents ())
m_bDlgOK = TRUE;
}
void SomeClass::A_Function ()
{
CMyDialog newDlg;
EditStartLabel:
if (IDCANCEL == newDlg.DoModal ())
goto EditEndLabel;
if (!newDlg.m_bDlgOK)
{ MessageBox ("One of the edits has an invalid value, please correct it", "Error", MB_OK);
goto EditStartLabel;
}
EditEndLabel:
return;
}
I know that is not an elegant code, but it works perfectly. I won't probably use this structure in my next project or if i rewrite this one in the future, so any tip, correction, opinion... will be wellcome.
But to start getting the concept about data validation in a "simple" way I think is good
Hope it helps
Greetings.
