InvalidateRect / UpdateWindow problem

[Terry Zivney]

I am having trouble getting my windows updated.
A snippet follows:

CASE %WM_PAINT

hDC = BeginPaint(hWnd, LpPaint)
GetClientRect hWnd, tRect
SetBkMode hDC, %TRANSPARENT
SetTextColor hDC, %black
EndPaint hWnd, LpPaint

FUNCTION = 0
EXIT FUNCTION

IF NEnd>0 THEN EnableMenuItem hMenu,%IDM_NARROW,%MF_ENABLED :_
EnableMenuItem hMenu,%IDM_REMOVE,%MF_ENABLED :_
EnableMenuItem hMenu,%IDM_PRINT,%MF_ENABLED :_
MENU DRAW BAR hMenu : _
CALL invalidaterect (hWnd,BYVAL %NULL,%False) : _
CALL updatewindow (hWnd)

The menubar is redrawn only if I minimize the window and
then restore it, or if I click a button in the window.

I qoute, from Win32.hlp: "The DrawMenuBar function redraws the menu bar of
the specified window. If the menu bar changes after Windows has created
the window, this function must be called to draw the changed menu bar. "

In other words, replace InvalidateRect and UpdateWindow with:

CALL DrawMenuBar(hWnd)

Thanks, that fixed the menu problem. Now a related problem.
code snippet:


CASE %WM_PAINT
hDC = BeginPaint(hWndRect3, LpPaint)
GetClientRect hWndRect3, tRect
SetBkMode hDC, %TRANSPARENT
SetTextColor hDC, %black
DrawText hDC,BYCOPY TextW, -1, tRect, %DT_WORDBREAK OR %DT_LEFT OR %DT_vcenter
EndPaint hWndRect3, LpPaint

hDC = BeginPaint(hWndRect4, LpPaint)
GetClientRect hWndRect4, tRect
SetBkMode hDC, %TRANSPARENT
SetTextColor hDC, %black
DrawText hDC,BYCOPY TitleW, -1, tRect, %DT_singleline OR %DT_CENTER OR %DT_VCENTER
EndPaint hWndRect4, LpPaint

hDC = BeginPaint(hWnd, LpPaint)
GetClientRect hWnd, tRect
SetBkMode hDC, %TRANSPARENT
SetTextColor hDC, %black
EndPaint hWnd, LpPaint

FUNCTION = 0
EXIT FUNCTION

IF NEnd=0 THEN TitleW="Noooo Records Selected" : StringZ="z" : _
TextW=StringZ : _
updatewindow hWndRect4


Again, same symptoms, window not updated until minimized/
restored, or messagebox moved over window, etc.

the following also did not work
CALL invalidaterect (hWnd,BYVAL %NULL,%False) : _
CALL updatewindow (hWnd)

Eureka!

hWndRect3 & hWndRect4 are child static windows in hWnd.
Thus, in WM_PAINT, I need to paint hWnd BEFORE hWndRect3 &
hWndRect4. Then, I invalidate hWnd, and everything
updates as expected.
