Disappearing Mouse Pointer

[jcfuller]

I chased this one for quite awhile this am.
The mouse pointer dissapears on my Win2k system when entering text in a single line edit box.
No problems on Win98SE.

Any Ideas???

Here is the source I used.

I think this is an actual "feature" of Windows 2000. In the Mouse pcl in
Control Panel there is an option called 'Vanish' that hides your mouse cursor
while you type.

Nathan,
I don't see it.
All I see is Enable pointer shadow.

James --
I see both - caret and cursor.
If you don't like standart cursor, SetClassLong GetDlgItem(hDlg, ...), %GCL_HCURSOR, ...

Semen,
The standard pointer is not the issue.
I thought I had problems with my code in an interpreter I'm working on
because the mouse pointer disappeared whenever I started entering text in an
edit field. It did not reappear until the mouse was moved or the alt key was pressed.
I finally tried the code on Win98 and it worked fine ( pointer did not disappear).

I don't see and never saw any troubles on my PC (Win2000 Pro + SP2)

   #Compile Exe
   #Dim All
   #Register None
   #Include "WIN32API.INC"
   
   %ID_TEXTBOX = 101

   Function PbMain
      Dim hDlg As Long
      Dialog New 0, "Any problems ?", , , 160, 45, %WS_OVERLAPPEDWINDOW To hDlg
      Control Add TextBox, hDlg, %ID_TEXTBOX, "", 10, 10, 80, 12
      SetClassLong GetDlgItem(hDlg, %ID_TEXTBOX), %GCL_HCURSOR, LoadCursor(ByVal 0, ByVal %IDC_ARROW)
      Control Add Button, hDlg, %IDOK, "Ok", 100, 5, 50, 14
      Control Add Button, hDlg, %IDCANCEL, "Cancel", 100, 26, 50, 14

Semen,
Same problem using your source. If the pointer is within the boundries of the
Dialog the pointer vanishes when you start entering text.

I have not applied SP2 yet.

Hmm ... Cusrsor temporary disappears, when you type symbols, and then appears again - yes.
Or it doesn't appear again on your PC at all ?

Semen,
The pointer appears again only if you move the mouse or press the Alt key.

James --
On my PC it appears again "automatic" and I don't remember another behaviour (I use Win2000 much more than one year and re-installed it many times).
Maybe time to think about Russian release ?

If seriously, it's obviously not Win2000 problem as it is.
If you have normal distributive (I mean non-upgrade/OEM variant), try to reinstall from "zero base" w/o installing external drivers.

Semen,
I just installed SP2. No change.
I was concerned that it was my program that caused it (when I first noticed it).
Now that I know that it's my system I can live with it, no big deal, but I am
still courious why??
I have Win2k installed on 2 systems and they both exhibit the same characteristics.
I do have W95DOSHERE (from prowertoys) installed on both systems??

Maybe it is a DDT dialog "feature"? Similar thing happens when one sets
MOUSEPTR 11 and THEN try to restore with MOUSEPTR 0. Must move mouse to
activate. Simple fix is to restore to MOUSEPTR 1. In this case it may
help to trap %EN_CHANGE notification under %WM_COMMAND and reset the
mouse pointer manually? Untested, but in dialog's callback:

CALLBACK FUNCTION DlgProc() AS LONG
  SELECT CASE CBMSG
     CASE %WM_COMMAND
        IF CBCTLMSG = %EN_CHANGE THEN MOUSEPTR 3 (or 1, whatever..)
  END SELECT
END FUNCTION

I just move the mouse to make sure it shows up as expected:

FUNCTION MoveCursor ALIAS "MoveCursor" () EXPORT AS LONG
LOCAL pnt AS pointapi
 
  GetCursorPos pnt
  IF pnt.x > 0 THEN
    SetCursorPos pnt.x - 1, pnt.y
  ELSE
    SetCursorPos pnt.x + 1, pnt.y
  END IF
  SetCursorPos pnt.x, pnt.y
END FUNCTION

Borje,
It's not just DDT. The original code where I first noticed it was straight SDK.

Peter,
A bit too much work.
To move the mouse(generate a WM_MOUSEMOVE) use the followng:

GetCursorPos tpt
SetCursorPos tpt.x, tpt.y
