Execute Function Until a window comes pop up
  Hi

I am working to close WFP (Windows File Protection) window
and find a solution in this forum to close WFP i need to call a function -closeWFP that can close WFP.

so what is my problem:

as you know WFP appears when you are trying to delete/modify protected files

so in my installation i need to delete a dll and after that it takes 5-10 seconds to WFP appears and if i call function before it pop nothing happend

for this issue i use sleep 10000 (ms) command bedfore calling -closeWFP

but i want to know
1) is there any way for me to detect WFP window and then call -closeWFP?

or

2) Is trhere any way to still running closeWFP function untill WFP window pop?

3) do you have any other suggestion for me?
i need your help urgently
Thanks in advanced

Try FindWindow. To get the window class (if it has one) you'd need to use Spy++ or a similar tool.

hi
Afrow UK
listen i can detect the windows and can close them too by calling a function so it is not my problem

as i told before it takes 5-10 seconds to apear windows
so i need wait for it and then call my function to close it

i asked a way to detect window immediately and close it

or

any way to still running closeWFP function untill WFP window pop

If you can detect the window then what is the problem? Just loop until you get a valid window handle (but ensure you don't loop infinitely as well).

thanks for answering...

i don't know how can i loop until i am newbie :)


this is a part of code that i told:

closeWFP

     Sleep 10000

   ;Find and close first dialog

    FindWindow$0 "" "Windows File Protection"

   System::Call 'user32::PostMessageA(i,i,i,i) i($0,${WM_COMMAND},2,0)'


   ;Find and close second dialog

    FindWindow$1 "" "Windows File Protection"

   System::Call 'user32::PostMessageA(i,i,i,i) i($1,${WM_COMMAND},6,0)'

>FunctionEnd 

>

Section -kbdfadll

SetOutPath "$SYSDIR"

  SetOverwrite on

  File "kbdfa.dll"

 ;!insertmacro InstallLib REGDLL NOTSHARED NOREBOOT_NOTPROTECTED kbdfa.dll $SYSDIRkbdfa.dll $SYSDIR

SectionEnd 

>

Section -WFP2

>;nsExec::Exec '"$INSTDIR\CWFP.exe"'

>call closeWFP

SectionEnd

Use IsWindow on $0. Again put in a Sleep 500 and a counter so you don't loop forever.

thanks i did it and it worked good

one anothr qudtion:

how can i repeat loop for x time
i mean like this:
for i=0 to 50
do it

i want this because in some case WFP windows will not pop and if i run this loop it wont break so i need repaet loop for 10 times only for example and if no window pop go to the end of function
this is my idea

but have you any other idea for my issue?

With LogicLib, ${For} $R0 1 1000 ... ${Next}

i write it with Do while but it didn't work what is wrong with it:

closeWFP


>${Do}

;Find and close first dialog

     FindWindow$0 "" "Windows File Protection"

   System::Call 'user32::PostMessageA(i,i,i,i) i($0,${WM_COMMAND},2,0)'


>;Find and close second dialog

    FindWindow$1 "" "Windows File Protection"

   System::Call 'user32::PostMessageA(i,i,i,i) i($1,${WM_COMMAND},6,0)'

    Sleep 500

     

>***91;B***93; ${LoopUntil} $0 == '1'***91;/B***93; 

>FunctionEnd

You cannot do it safely without a counter. Use a For loop.

Yes! it works :)
this is because i did not know StrCmp

Thank you so much for your time

I used StrCmp instead of IsWindow because FindWindow returns 0 if no windows are found. It could have been IsWindow $R1 Close as well.
