run quick translator by c#

As part of my initial certification, I wrote an FME Launcher application in C#. This allows you to select a workspace, from multiple directories. It then displays the user parameters for you to modify as necessary before clicking go - which runs the workspace from the command line.

Hi @sveurink,

Please ensure that you have declared FMEObjects in your C# source file:

using Safe.FMEObjects;

The different FMEObjects APIs name their objects and methods a bit differently. For C#, you should call:

bool didItRun = FMEOWorkspaceRunner.PromptRun();

didItRun will be given the value of true if the workspace ran successfully, false otherwise.

Please show me your code for the section where you want to run the workspace, and which variable you are storing the workspace location in.

        private void button1_Click(object sender, EventArgs e)
        {
            
        }

private void Projectie_Click(object sender, EventArgs e)
        {
            dynamic acadapplication = Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication;
            acadapplication.loaddvb(@"P:\.....\Dwarsprofiel_03_R2017 v4.1.dvb");
            acadapplication.runmacro("projectieNLCS");
        }

Hi @sveurink,

Please try:

        private void button1_Click(object sender, EventArgs e)
        {
            bool didItRun = FMEOWorkspaceRunner.PromptRun(@"c:\temp\myworkspace.fmw"); 
        }

Also add the following to the top of your file:

using Safe.FMEObjects;

Hi @sveurink,

Sorry, that was a mistake on my part - forgot the preceding 'I'. Please try:

private void button1_Click(object sender, EventArgs e)
        {
            bool didItRun = IFMEOWorkspaceRunner.PromptRun(@"c:\temp\myworkspace.fmw"); 
        }

You will also need to add a reference in your project to 'C:\Program Files\FME\FMEObjectsDotNet4.dll.

Hi @sveurink,

I'm sorry, it's been a while since I used FMEObjects in C#. I forgot the most important part: creating the FMEObjects session.

There is a good example in Program Files\FME\fmeobjects\samples\CSharp\Viewer. It's fairly large, but it does illustrate how FMEObjects should be used.

In the MainForm method, FME Objects is initialized by creating an FME session, and a log object is created for logging any warnings or errors

         // Create the session object. Every FME Objects application requires
         // a session
         fmeSession_ = FMEObjects.CreateSession();

         // Always initialize the session. If no special initialization is
         // needed, simply set it to null or pass in an empty StringCollection
         // as a parameter, otherwise pass in a StringCollection containing
         // initialization directives.
         StringCollection sessionDirectives = new StringCollection();
         sessionDirectives.Add("FME_USE_RICH_GEOMETRY");
         sessionDirectives.Add("yes");
         fmeSession_.Init(sessionDirectives)
         
         // Get the log file
         DirectoryInfo dirOneLevelUp = Directory.GetParent(Directory.GetCurrentDirectory());
         DirectoryInfo dirTwoLevelUp = Directory.GetParent(dirOneLevelUp.FullName);
         string logFileDir = dirTwoLevelUp.FullName;

         fmeLogFile_ = fmeSession_.LogFile();
         fmeLogFile_.SetFileName(logFileDir + @"\CSharpViewer.log", false);

The Button click methods brings up a dialog to locate the workspace, and sends it to another method to actually run the workspace. Any errors are posted to the log file:

      //-----------------------------------------------------------------------
      // PromptRunWorkspace_Click
      private void PromptRunWorkspace_Click(object sender, EventArgs e)
      {
         // Bring up a file select dialog.
         OpenFileDialog fileDialog = new OpenFileDialog();
         fileDialog.Filter = "FME Workspaces (*.fmw)|*.fmw";
         fileDialog.Title = "Select Workspace";

         String workspace = "";
         if (fileDialog.ShowDialog() == DialogResult.OK)
         {
            workspace = fileDialog.FileName;
         }

         fileDialog.Dispose();
         fileDialog = null;

         if (workspace != null)
         {
            if (workspace == "")
            {
               // User pressed cancel
               fmeLogFile_.LogMessageString("User Pressed Cancel.",
                                            FMEOMessageLevel.Inform);
               return;
            }
            fmeLogFile_.LogMessageString("Workspace selected: " + workspace,
                                         FMEOMessageLevel.Inform);
            try
            {
               PromptRunFMEWorkspace(workspace);
            }
            catch (FMEOException ex)
            {
               // Log errors to log file
               fmeLogFile_.LogMessageString(ex.FmeErrorMessage, FMEOMessageLevel.Error);
               fmeLogFile_.LogMessageString(ex.FmeStackTrace, FMEOMessageLevel.Error);
               fmeLogFile_.LogMessageString(ex.FmeErrorNumber.ToString(), FMEOMessageLevel.Error);

               // Clean up any outstanding objects
               this.Dispose();
               // Now exit the application
               Application.Exit();
            }
         }
      }

The Button click method calls the following to actually run the workspace:

      //=====================================================================
      public bool PromptRunFMEWorkspace(String workspace)
      {
         IFMEOWorkspaceRunner runner = fmeSession_.CreateWorkspaceRunner();
         // Run the workspace
         bool success = runner.PromptRun(workspace);
         runner.Dispose();

         if (success)
         {
            MessageBox.Show("The workspace was run successfully, check log file for details.",
                            "FME Run Workspace", MessageBoxButtons.OK,
                            MessageBoxIcon.Information);
            fmeLogFile_.LogMessageString("The workspace was run successfully",
                                         FMEOMessageLevel.Inform);
         }
         else
         {
            MessageBox.Show("The workspace run failed, check log file for details.",
                            "FME Run Workspace", MessageBoxButtons.OK,
                            MessageBoxIcon.Error);
            fmeLogFile_.LogMessageString("The workspace run failed",
                                         FMEOMessageLevel.Error);
         }

         return success;
      }

Hey everybody, I'm back, same problem. 

Last time i got it working with following code: 

public void button1_Click(object sender, EventArgs e)
        {
            string relativepathFME = Path.Combine(assemblypath, @"blablabla.fmw");
            string fullpathFME = Path.GetFullPath(relativepathFME);
 
            Process.Start("fmequicktranslator.exe");
            Process.Start(fullpathFME);
        }

However, we have updated FME version now to 2020.2, and when I run this now, it starts up FME and the quicktranslator separately. 

And when going back to the solution offered here, being: 

private void button1_Click(object sender, EventArgs e)
        {
            bool didItRun = IFMEOWorkspaceRunner.PromptRun(@"c:\temp\myworkspace.fmw"); 
        }

I still get same error: "an object reference is required for the non static field, method, property '...' "

So any ideas on this issue allready? The reference "FMEObjectsDotNet4.dll" is added correctly, also "using Safe.FMEObjects;" is in the code.

BTW the code above in the post above this one (#13) might be helpfull but it is way to complicated for me, doesn't make me ring any bells. But thanks anyhow
