CreateProcess() を使用して実行可能ファイルを実行し、最後に GetExitCodeProcess() を呼び出してプロセスの終了コードを取得します。アプリケーション検証ツールで実行すると、初回例外が発生します。ログの写真を添付しました。
行番号 1348 は、GetExitCodeProcess() 呼び出しの直後の行です。私はログ形式にあまり詳しくないので、GetExitCodeProcess() 内でスローされた例外を尋ねています。この場合、それを無視できますか、または GetExitCodeProcess への呼び出しの後の行を指しているため、コードで何か間違ったことをしていますか? ()?
編集:私のコード:
if (!CreateProcess(
NULL, // it will get the app name from the next argument
cString, // command line
NULL,
NULL,
TRUE, // don't inherit handles
CREATE_NO_WINDOW,
NULL, // use environment of the calling process
NULL, // use same current drive and directory as the calling process
&siStartupInfo,
&processInfo
))
{
// If process failed return error
...
}
// Close handles the passed to the child process.
CloseHandle(hChildStd_ERR_Wr);
CloseHandle(hChildStd_OUT_Wr);
// Now read the std::out and std::err from child process and store them in strings to return
DWORD dwRead;

}
consoleOutput = out;

// Wait for the process to finish. Wait shouldn't happen before reading from pipes because
// pipe writes happen only when someone is reading from them. For small amounts of data
// this would not be a problem because the Pipe Manager buffer will consume data so the

// the writer will wait indefinitely.
WaitForSingleObject(processInfo.hProcess,INFINITE);
// Close handles returned from Child process
CloseHandle(processInfo.hProcess);
CloseHandle(processInfo.hThread);
