Is SetShellVarContext synchronous ? (Win98SE)

[Nicolas Cuny]

Is SetShellVarContext instruction not synchronous ? It seems not to work immediately.

My script has some problem on my freshly installed MS Windows 98 Second Edition. The machine is a Pentium II 350 MHz with 128 MB of RAM.

In my full script, when installing, $DESKTOP is called after a few minutes of execution as there are many files copied. Its value is C:\WINDOWS\All Users\Desktop as expected. The problem is that during the uninstalling process, being much shorter in time, the value of $DESKTOP is C:\WINDOWS\Desktop. On my Windows 2000 and Windows XP machines there is no problem with the same .exe installer.

The script can be stripped down to this test file :

code:
Name "Context98"

OutFile "Context98.exe"



Section "-Context98" SEC01

  MessageBox MB_OK "$DESKTOP"

  CreateShortCut "$DESKTOP\Context98.lnk" "$EXEDIR\Context98.exe"

  WriteUninstaller "$EXEDIR\UnContext98.exe"

SectionEnd



Section Uninstall

  MessageBox MB_OK "$DESKTOP"

  Delete "$DESKTOP\Context98.lnk"

SectionEnd



Function .onInit

  MessageBox MB_OK "$DESKTOP"

  SetShellVarContext all

  MessageBox MB_OK "$DESKTOP"

FunctionEnd



Function un.onInit  

  MessageBox MB_OK "$DESKTOP"

  SetShellVarContext all

  MessageBox MB_OK "$DESKTOP"

FunctionEnd

With this simple script and Windows 98, the value of $DESKTOP is never C:\WINDOWS\All Users\Desktop but always C:\WINDOWS\Desktop.

The important part is that the

code:
  MessageBox MB_OK "$DESKTOP"

  SetShellVarContext all

  MessageBox MB_OK "$DESKTOP"

section displays twice C:\WINDOWS\Desktop on Windows 98.

There is only one user account on the machine.

It's synchronous. See bug report #1008632.
