use OpenFileDialog in "Dynamic code (.NET SDK" type universal function

Dave Dai

Trying to create a OpenFileDialog like: 

 

using (OpenFileDialog openFileDialog = new OpenFileDialog())
{
    openFileDialog.InitialDirectory = "c:\\";
    openFileDialog.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";
    openFileDialog.FilterIndex = 2;
    openFileDialog.RestoreDirectory = true;

    if (openFileDialog.ShowDialog() == DialogResult.OK)
    {
...
...

does not work, and it renders SAP unresponsive. 

Is it possible to let the user choose a file when executing a universal function? If yes, how?

    I later found that you can use a new process to do this.  

    The code for universal function would be like follows. choose-file.exe would be a simple application that displays the choose file dialog and outputs the filename to console.  

    Directory.SetCurrentDirectory("D:\\Debug"); // this is where choose-file.exe is 
    var process = new Process{
        StartInfo = new ProcessStartInfo{
            FileName = "choose-file.exe",
            UseShellExecute = false,
            RedirectStandardOutput = true,
            CreateNoWindow = true
        }
    };
    process.Start();
    while (!process.StandardOutput.EndOfStream)
    {
        var line = process.StandardOutput.ReadLine();
        application.StatusBar.SetText(line);
    }
    process.WaitForExit();
