Selection change in dialog box..

[Shah Satish]

Hi !!! First of all i am sorry for deleting my question..Here still i have problem..look In my Application,I created one dialog box..In this dialog box,I cretaed small 2 boxes.One is for list of Symbol ( text ) and second box is for preview of the drawing. For exam:- Box1: Box 2 ( preview ) Exchanger-Double end Exchanger-Single end Exchanger-Double end kettle My requirement is, If I will click on Exchanger-Double end ( box1) from dialog box then it will show me drawing of Exchanger-Double end ..If I will click on Exchanger-Single end then it will show me preview of Drawing Exchanger-Single end. My code is:-

BOOL CDwgPvDLG::OnInitDialog()
{
CDialog::OnInitDialog();

//CDwgPreview    

m\_mytext.AddString(\_T("Exchanger-Double end"));
  m\_mytext.AddString(\_T("Exchanger-Single end"));
  m\_mytext.AddString(\_T("Exchanger-Double end kettle"));
 

  m\_mytext.SetCurSel(0);

  mydwg = \_T("C:\\\\Symbol\\\\Exchangers\\\\Exchanger\_1\_i.dwg");





return TRUE;

}

void CDwgPvDLG::OnPaint()
{

// this is class for Preview of the drawing.


CDwgPreview ::ShowInDialog (mydwg,this,IDC\_PVTYP);

CPaintDC dc(this); // device context for painting
// TODO: Add your message handler code here
// Do not call CDialog::OnPaint() for painting messages

}

void CDwgPvDLG::OnselectionchangeList()
{
// TODO: Add your control notification handler code here

int nEntry = m_mytext.GetCurSel();

switch (nEntry)

{

case 0:
mydwg = _T("C:\\Symbol\\Exchangers\\Exchanger_1_i.dwg");
break ;

case 1:

 mydwg = \_T("C:\\\\Symbol\\\\Exchangers\\\\Exchanger\_2\_i.dwg");
 break ; 

case 2:

 mydwg = \_T("C:\\\\Symbol\\\\Exchangers\\\\Exchanger\_3\_i.dwg");

 break;

}

}

Anybody know How can I do it ?? Thanking you.. Shah

See, u handle the selection event of the list, and upon notifying, draw the things in the other box. Where the problem is?

What does this function do ? Have considered the fact that, you need to invalidate the rectangle , before drawing to it ? Can you be clear about your problem ?
