System.Windows.Forms.TabControl .net 1.0

ups det heder jo 1.1

du skal bruge noget i denne stil:
[StructLayout(LayoutKind.Sequential)]
struct NMHDR
    {
    public IntPtr hwndFrom;
    public uint idFrom;
    public uint code;
    };

protected override void WndProc(ref System.Windows.Forms.Message m)
    {
    const uint WM_NOTIFY = 0x004E;
    const uint TCN_FIRST = 0xFFFFFDDA;
    const uint TCN_SELCHANGING = TCN_FIRST - 2;
    base.WndProc(ref m);

    switch ((uint)m.Msg)
    {
          case WM_NOTIFY:
          {
              int idCtrl = (int)m.WParam;
              NMHDR nmh = (NMHDR)m.GetLParam(typeof(NMHDR));
              if (nmh.code == TCN_SELCHANGING)
                    {
                    if (DisableTab)
                        MessageBox.Show("You cannot change the tab while processing");
                    else
                        {
                        //put your code here
                        }
                    }
              m.Result = (IntPtr)1;
              break;
              }
          }
    }

Det virker tak for det !!!

Det virker tak for det :-)

np smider lige et svar :)

fik godt nok ikke brug for det hele men det her virker
protected override void WndProc(ref System.Windows.Forms.Message m)
{
  base.WndProc(ref m);
  if(m_DataFunction == eDataFunction.Create && valgt )
  {
    const uint WM_NOTIFY = 0x004E;
                   
    if ( (uint)m.Msg == WM_NOTIFY )
    {
      if (ValidateForm())
      {
          FromGUI2State();
          m_Object.Validate();
          valgt = false;
      }
    }
    m.Result = (IntPtr)1;
  }

prøver lige igen
svar :)
