Button Caption

[shiv nand]

CWnd::SendDlgItemMessage, i have no idia if you give example, it is very helpful to me.

[CPallini]

Inside a method of your window class (the parent window of your buttons) call, for instance:

SendDlgItemMessage(5000, WM_SETTEXT, 0 , (LPARAM) _T("BUTTON 0"));

[CPallini]

If you post your (relevant) code may be I can tell you how to modify it. :)

ON_COMMAND_RANGE(5000,5100,OnButtonRange) void CTest::OnShowWindow(BOOL bShow, UINT nStatus) { CDialog::OnShowWindow(bShow, nStatus); CButton* m_btDynamic; CString csText; int k=0; for(int i=0;i<5;i++) { m_btDynamic = new CButton(); csText.Format(L"Button %d",i+1); m_btDynamic->Create(csText, BS_FLAT|WS_VISIBLE|WS_CHILD|BS_PUSHBUTTON|BS_ICON, CRect(10+k ,10+k,60+k,60+k),this, 5000+i); k=k+30; } } void CTest::OnButtonRange(UINT nIDforControl) { int iSelectedControlID; iSelectedControlID = nIDforControl; // here i want button caption } Where i should use SendDlgItemMessage()

[CPallini]

Well, you already set the caption for you button with known values, so what's your need now? BTW I suggest you to maintain the CButton pointers in a member variable: in class declaration:

CButton * m_btDynamic[5];

then, in you function you may do

void CTest::OnShowWindow(BOOL bShow, UINT nStatus)
{
CDialog::OnShowWindow(bShow, nStatus);

 CString csText;    
 int   k=0;
     
 for(int i=0;i<5;i++)
 {
   m\_btDynamic\[i\] = new CButton();
          
   csText.Format(L"Button %d",i+1);         
   m\_btDynamic\[i\]->Create(csText,BS\_FLAT|WS\_VISIBLE|WS\_CHILD|BS\_PUSHBUTTON|BS\_ICON,
       CRect(10+k ,10+k,60+k,60+k),this, 5000+i);
    k=k+30;
 }

}

so that whenever you need to access the caption of, say, third button, you may call

m_btDynamic[2]->GetWindowText();

thanks CPallini, this is not exact code i have posted. in my actual code i have created 100 buttons, same way as u told. but the problem is if user right click on any button i want that caption.

[CPallini]

You may do this way (in your event handler):

CButton * pClickedButton = (CButton *) GetDlgItem( id ); // the id is known, as you stated
CString sClickedCaption = pClickedButton->GetWindowText();

Sorry, I should have fixed it now. :)

It's GetWindowText, not GetText. But if you look at the documentation for CWnd on msdn, you can see the details for yourself too. Good luck! Iain.

[shiv nand]

Who do you think you are, God? (I was worried that you missed a certain poster's rants.)

To your knees! (to hear the softly spoken magic spells) :-\
