尝试从 c# 调用 VB6 应用程序时出现文件/访问错误

Question

        ProcessStartInfo procStartInfo = new ProcessStartInfo("cmd", "/c " + "MyExecutable.exe");            
        procStartInfo.RedirectStandardOutput = true;
        procStartInfo.UseShellExecute = false;            
        procStartInfo.CreateNoWindow = true;


        Process proc = new Process();
        proc.StartInfo = procStartInfo;
        proc.Start();

I have an executable in my project, say "MyExecutable.exe". When running this application, it will create a log file in the same path where this exe is executed.

If I run this exe in command prompt, I have no issues.

But If I run the exe from c# code, it is throwing error "File/Access Error" in the below code which is in MyExecutable.exe

Open `sLogfile` For Output Access Write As `LogFileNumber`

where sLogfile is the logfile name and LogFileNumber is the FreeFile .

Answer 1

Current guidance says to not write logs into an executable directory. This is probably Windows enforcing this guidance. Write to the user's AppData directory instead.
