Script-Problem: Waiting for Window
Dear Friends,

the following script-part should be responsible for waiting until a window with the caption "xxx" is shown and closes the splashscreen with a call on newadvsplash::stop then.


NSIS-CODE:
"
[...]

TheEnd:
Call func

SectionEnd

Function func
loop:
sleep 10
FindWindow $0 "" "xxx"
IsWindow $0 0 loop
System::Call 'user32::SetForegroundWindow(i r0)'
newadvsplash::stop
FunctionEnd
"


But it doesnt work:
The splash is closed before the window is shown.

Please help me!

Thank you very much
With best regards!
MfG

Perhaps it would be better to compare the FindWindow value with 0 with StrCmp instead. Also the Sleep should probably be increased to 500ms at least (otherwise your code is being executed 100 times a second).

Well, could you show me how to do that here:
IsWindow $0 0 loop

Thank you very much!

Also, what if the program launch fails? You will have an infinite loop on your hands.

StrCpy $1 0
loop:
  StrCmp $1 10000 exit
  IntOp $1 $1 + 1
  Sleep 500
  FindWindow $0 "" "xxx"
StrCmp $0 0 loop
exit:

System::Call 'user32::SetForegroundWindow(i r0)'
newadvsplash::stop
