>From Delphi 7 Language, I use the next well know routine for call external
programs an wait for terminate it.
function WinExecAndWait32(FileName: string; Visibility: Integer): dWord;
var
zAppName: array[0..512] of Char;
zCurDir: array[0..255] of Char;
WorkDir: string;
StartupInfo: TStartupInfo;
ProcessInfo: TProcessInformation;
begin
StrPCopy(zAppName, FileName);
GetDir(0, WorkDir);
StrPCopy(zCurDir, WorkDir);
FillChar(StartupInfo, Sizeof(StartupInfo), #0);
StartupInfo.cb := Sizeof(StartupInfo);
StartupInfo.dwFlags := STARTF_USESHOWWINDOW;
StartupInfo.wShowWindow := Visibility;
if not CreateProcess(nil,
zAppName, { pointer to command line string }
nil, { pointer to process security attributes }
nil, { pointer to thread security attributes }
false, { handle inheritance flag }
CREATE_NEW_CONSOLE or { creation flags }
NORMAL_PRIORITY_CLASS,
nil, { pointer to new environment block }
nil, { pointer to current directory name }
StartupInfo, { pointer to STARTUPINFO }
ProcessInfo) then
Result := -1 { pointer to PROCESS_INF }
else
begin
WaitforSingleObject(ProcessInfo.hProcess, INFINITE);
GetExitCodeProcess(ProcessInfo.hProcess, Result);
CloseHandle(ProcessInfo.hProcess);
CloseHandle(ProcessInfo.hThread);
end;
end;
With any one application it works well. In a debug session I can see that
the step by step execution stops in WaitforSingleObject instruction and continue
when I close the external program.
The problem is that with OpenOffice, executable starts well but they ignore
the WaitforSingleObject an continue, OpenOffice are open and my application
continues. They don't wait for OpenOffice execution end. :(
I tested a lot of programs and I see that only OpenOffice fails.
I need it for integration projects.
Thank you very much.
