How to get a Child Form from a Parent Form in IEE IFS10

Example 1:

frmCmpcfgCUTemplateContainer_Cust frmCmpcfgCUTemplateContainerCust = ((frmCmpcfgCUTemplateContainer_Cust)SalWindow.FromHandle(this.cResizeSplitter1.SplitterGetSecond(), typeof(frmCmpcfgCUTemplateContainer_Cust)));
               
SalNumber nActivatedTab = frmCmpcfgCUTemplateContainerCust.picTab.FindName("GeneralExecutionItem");

frmCmpcfgExItemsGeneral_Cust frmCmpcfgExItemsGeneralCust = ((frmCmpcfgExItemsGeneral_Cust)SalWindow.FromHandle(frmCmpcfgCUTemplateContainerCust.picTab.GetPageWindow(nActivatedTab), typeof(frmCmpcfgExItemsGeneral_Cust)));

frmDispatchListTabContainer_Cust tabCon = frmDispatchListTabContainer_Cust.FromHandle(this.GetParent());

frmDispatchListOperation_Cust ops = ((frmDispatchListOperation_Cust)SalWindow.FromHandle(frmDispatchListSplitter.FromHandle(tabCon.GetParent()).ccDispatchListSplitter.SplitterGetFirst(), typeof(frmDispatchListOperation_Cust)));
