ShellExecWait

Author: Anders (talk, contrib)

Basic code for waiting on a "ExecShell" (Note that you can only wait on programs, not documents or URL's)

!include LogicLib.nsh
!include WinMessages.nsh
 
#define SEE_MASK_NOCLOSEPROCESS 0x40 
System::Call '*(&i60)i.r0'
System::Call '*$0(i 60,i 0x40,i $hwndparent,i,t "calc.exe",i ,i,i ${SW_SHOW})i.r0'
System::Call 'shell32::ShellExecuteEx(ir0)i.r1 ?e'
${If} $1 <> 0
	System::Call '*$0(is,i,i,i,i,i,i,i,i,i,i,i,i,i,i.r1)' ;stack value not really used, just a fancy pop ;)
	System::Call 'kernel32::WaitForSingleObject(ir1,i-1)'
	System::Call 'kernel32::GetExitCodeProcess(ir1s,*i.r1)'
	System::Call 'kernel32::CloseHandle(is)'
 
${Else}
	pop $1
${EndIf}
System::Free $0
 
MessageBox mb_ok "exitcode or error=$1"
