You could use a CFormView instead.
Put the buttons where you want and a list control onto the dialog in the resource editor

How do you add values to the list control?  (Check it is in report mode - I assume you want columns of information).

BeginWaitCursor();
 CDatabase * commonDatabase = CTresManApp::GetDatabaseObject();
 ErrorRepository errorRep(commonDatabase);
 
 //get the filter (if any) from the network tree. If no filter is available, then
 //the whole NodeList table is considered when generating the task list table contents
// CString taskFilter = m_nwSplitter.GetNwTreeFilter();
 CString taskFilter = m_nwSplitter2.GetNwTreeFilter();
 //fill database with scan tasks
 TaskListDbHandler::Instance()->FillTaskListTable(taskFilter);
 CTresManApp * pApp = (CTresManApp *)AfxGetApp();
 ASSERT(pApp);
 
/**/CTaskFormView * pNwVList1 = (CTaskFormView *)m_nwSplitter2.GetPane(2,0);
 CTaskListView * pNwVList=(CTaskListView *)pNwVList1->GetTaskListView();
 ASSERT(pNwVList);

/* CDbView * tskvw = (CDbView *) pApp->GetView(CTresManStates::Views::TASKFORMVIEW);
 ASSERT(tskvw);
 //set the dirty flag for the recordset. Recordset will be requeryd. This one is for the TaskList view
 if (tskvw)
 {
  tskvw->SetRecordsetDirty();
 }*/
 if (pNwVList)
 {
  pNwVList->SetRecordsetDirty();
 }
 EndWaitCursor();

Are you getting any records back from the database ?


What is the code in SetRecordsetDirty ?

You have still not posted the code that is for adding the items to the list control.

Please confirm that CTaskListView is based on the CListCtrl class.

Well, you add controls to a resource dialog - so you need to link the control on the dialog to a member variable.
Select the control in resource editor, select add variable and add a CONTROL variable of type CListCtrl.

Now give your code another try.
