the other value is the resource ID of the next dialog you want to display.

I've had the same problem a couple weeks ago ... bloody MSDN ...

Color of text in CStatic control

Hello, I would like to have the text of the static control printed in red (just for one of them on my dialog). Is it possible to do that without subclassing the control ?

Thanks

1) Assign an ID to the static control you want to have the red text. (i.e. IDC_REDTEXT_STATIC)

2) Add a handler for OnCtlColor in your dialog.

3) Check for the control ID in OnCtlColor, and update the device context text color to red:

<br />
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
   HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
// add this code<br />
if (pWnd->GetDlgCtrlID() == IDC_REDTEXT_STATIC)<br />
   pDC->SetTextColor(RGB(255,0,0));<br />
<br />
	// TODO:  Return a different brush if the default is not desired<br />
	return hbr;<br />
}<br />

Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Dialog Variable can not be assigned

Hello!
I have got the following problem!

Ich have written a Dll for a Socket Connection. This Dll call a callback function when it receives a Msg over the net.
The function which is called from the dll is a global function in my Testapplication. The global function calls my receive function which only copys the msg in two Membervariablen from the Dialog. These Membervariablen are undefined (Debug shows: ???) and the program crashs.

Global receive function
void gReceiveMsg(CMsg *pMsg)
{
((CSocketTesterApp*)AfxGetApp())->CallbackReceiveMsg(pMsg);
}

function in my application (the values are received correct )
void CSocketTesterApp::CallbackReceiveMsg(CMsg *pMsg)
{
CString sVar = "";
double nVal =0;
pMsg->GetData(&sVar,&nVal);
((CSocketTesterDlg*)AfxGetMainWnd())->ReceiveMsg(sVar,nVal);
}

receive function in my Dialog
void CSocketTesterDlg::ReceiveMsg(CString sVariable, double nValue)
{
m_sRecVariable = sVariable;
m_nRecValue = nValue;
UpdateData(FALSE);
}

The Program crashs after the assignment to the membervariable.
I hope someone can help me!!!

I’m using a CTreeCtrl to display an hierarch structure of a database. Is it possible to allow the user to select multiple items using for e.g. “shift” and “ctrl”?

Thanks / Anders

I don't think it's in the standard CTreeCtrl behaviour; google for CMultiTree it handles multiselection.

hi,
If u are doing this using Visual C++/MFC ,It is very easy to set Multiple selection to the ListBox.
Go the properties of the added List Box change the selection to 'Multiple'.
That's all.

How many times are you calling this function?

That doesn't make sense...

Give an example of what you want. Do you want a random alphanumeric character? Or does this have to do with Keyboard Input?

Something like:

char RandomNumber( void )

}
 
char RandomUpper( void )
{
    return (rand() % 26) + 65;
}
 
char RandomLower( void )
{
    return (rand() % 26) + 97;
}
