在程序中如何让第一条命令执行完后再执行第2行

[gao]

如：
winexec();
RenameFile();

要求：执行winexec();完成后再执行renameFile()

或如何取得WINEXEC（）；的句柄

// Execute the Windows Calculator and pop up
// a message when the Calc is terminated.
uses ShellApi;
...
var
SEInfo: TShellExecuteInfo;
ExitCode: DWORD;
ExecuteFile, ParamString, StartInString: string;
begin
ExecuteFile:='c:\Windows\Calc.exe';

FillChar(SEInfo, SizeOf(SEInfo), 0);
SEInfo.cbSize := SizeOf(TShellExecuteInfo);
with SEInfo do begin
fMask := SEE_MASK_NOCLOSEPROCESS;
Wnd := Application.Handle;
lpFile := PChar(ExecuteFile);
{
ParamString can contain the
application parameters.
}
// lpParameters := PChar(ParamString);
{
StartInString specifies the
name of the working directory.
If ommited, the current directory is used.
}
// lpDirectory := PChar(StartInString);
nShow := SW_SHOWNORMAL;
end;
if ShellExecuteEx(@SEInfo) then begin
repeat
Application.ProcessMessages;
GetExitCodeProcess(SEInfo.hProcess, ExitCode);
until (ExitCode <> STILL_ACTIVE) or
Application.Terminated;
ShowMessage('Calculator terminated');
end
else ShowMessage('Error starting Calc!');
end;

用CreateProcess()
WaitForsingleObject(..., ...）
