SaveFrmAddress (DllFormName);//handle to temporarily store
ChildHandle:=StrToInt (FFrmIni. ReadString (' FrmList DllFormName, '0'));/when open the child form, will be stored in child form the Ini file, handle to open again read value, storage handle way is rigid is to read and write Ini file
If ChildHandle=0, then no opened,//sense to open too won't go to call DLL files, no open call DLL file is loaded into the main form of
RunDllForm (DllFileName DllFormName, Parameter, FrmCaption, 'ShowForm')//open for the first time can be displayed to the main form
