Hi, i found those lines of codes in Export EDL,js, but i can't figure out how to convert them to c sharp. The ideea is that when you try to run the script, but a project has no tracks (video or audio), a message box shoud appear saying that are no tracks to export.
var videoTrack = FindTopTrackOfType(MediaType.Video);
var audioTrack = FindTopTrackOfType(MediaType.Audio);
if ((null == videoTrack) && (null == audioTrack))
{
throw "no tracks to export";
}
"FindTopTrackOfType" will be a function in the code you are writing. So that routine would need to be correct as well. But those lines could be:
Track videoTrack = FindTopTrackOfType(MediaType.Video);
Track audioTrack = FindTopTrackOfType(MediaType.Audio);
if ((null == videoTrack) && (null == audioTrack))
{
throw "no tracks to export";
}
You have to change all "var" statements to be the type of variable it will be receiving. So the "FindTopTrackOfType" must return a type of "Track".
Sorry i'm new in programming. I work on the same script that you helped before, i thought it will be simpler. This is my code so far:
using System;
using System.Text;
using System.Collections.Generic;
using System.Windows.Forms;
using ScriptPortal.Vegas;
public class EntryPoint
{
public void FromVegas(Vegas vegas)
{
string tk_error = "Text2Reg error:";
string tk_warning = "Text2Reg Warning:";
//find tracks
// Track videoTrack = FindTopTrackOfType(MediaType.Video);
// if (null == videoTrack))
// {
// MessageBox.Show(String.Format("No video track to export"),tk_error);
// }
foreach (Track track in vegas.Project.Tracks)
{
try
{
// only the selected tracks
if (!track.Selected) continue;
foreach (TrackEvent trackEvent in track.Events)
{
Media media = trackEvent.ActiveTake.Media;
OFXEffect ofxEffect= media.Generator.OFXEffect;
OFXStringParameter txtparam = (OFXStringParameter) ofxEffect.FindParameterByName("Text");
RichTextBox rtfText = new RichTextBox();
rtfText.Rtf = txtparam.Value;
string MiniActiveTakeName = rtfText.Text;
if (MiniActiveTakeName == "")
{
if (MessageBox.Show("Some media contains no text.\r\nDo you want to continue?",
tk_warning, MessageBoxButtons.YesNo) == DialogResult.No)
{
vegas.Project.Regions.Clear();
return;
}
}
Region region = new Region(trackEvent.Start, trackEvent.Length, MiniActiveTakeName);
try
{
vegas.Project.Regions.Add(region);
}
catch (Exception e)
{
MessageBox.Show(String.Format("Couldn't place Region at {0}\nThe error message: {1}", trackEvent.Start.ToString(), e.Message));
}
}
}
catch (Exception e)
{
MessageBox.Show(String.Format("Selected track has no media text\r\nor some media text are in (Legacy) Text.", e.Message),tk_error);
vegas.Project.Regions.Clear();
return;
}
}
}
// public void FindTopTrackOfType(mediaType) :Track
// {
// var trackEnum = new Enumerator(Vegas.Project.Tracks);
// while (!trackEnum.atEnd()) {
// var track : Track = Track(trackEnum.item());
// if (track.MediaType == mediaType) {
// return track;
// }
// trackEnum.moveNext();
// }
// return null;
// }
}
The code works i just want to add an option, if a project has no tracks to give me a error message. The only script that i saw doing that is Export EDL.js but is js no cs.
You don't need to check up front. Just count the tracks as you process them. Then if there were no tracks to process, display that message:
using System;
using System.Text;
using System.Collections.Generic;
using System.Windows.Forms;
using ScriptPortal.Vegas;
public class EntryPoint
{
public void FromVegas(Vegas vegas)
{
string tk_error = "Text2Reg error:";
string tk_warning = "Text2Reg Warning:";
int CountTracks = 0;
foreach (Track track in vegas.Project.Tracks)
{
try
{
// only the selected tracks
if (track.Selected)
{
CountTracks++;
foreach (TrackEvent trackEvent in track.Events)
{
Media media = trackEvent.ActiveTake.Media;
OFXEffect ofxEffect= media.Generator.OFXEffect;
OFXStringParameter txtparam = (OFXStringParameter) ofxEffect.FindParameterByName("Text");
RichTextBox rtfText = new RichTextBox();
rtfText.Rtf = txtparam.Value;
string MiniActiveTakeName = rtfText.Text;
if (MiniActiveTakeName == "")
{
if (MessageBox.Show("Some media contains no text.\r\nDo you want to continue?",
tk_warning, MessageBoxButtons.YesNo) == DialogResult.No)
{
vegas.Project.Regions.Clear();
return;
}
}
Region region = new Region(trackEvent.Start, trackEvent.Length, MiniActiveTakeName);
try
{
vegas.Project.Regions.Add(region);
}
catch (Exception e)
{
MessageBox.Show(String.Format("Couldn't place Region at {0}\nThe error message: {1}", trackEvent.Start.ToString(), e.Message));
}
}
}
}
catch (Exception e)
{
MessageBox.Show(String.Format("Selected track has no media text\r\nor some media text are in (Legacy) Text.", e.Message),tk_error);
vegas.Project.Regions.Clear();
return;
}
}
if (CountTracks == 0)
{
MessageBox.Show("There were no selected tracks to process");
}
}
}
But, if you do want to check ahead of time, this modification to your code will let you do that. The subroutine has been converted to C# and it can now be properly called.
using System;
using System.Text;
using System.Collections.Generic;
using System.Windows.Forms;
using ScriptPortal.Vegas;
public class EntryPoint
{
Vegas myVegas = null; // This is so the subroutine can access the "Vegas" variable
public void FromVegas(Vegas vegas)
{
myVegas = vegas; // This is so the subroutine can access the "Vegas" variable
string tk_error = "Text2Reg error:";
string tk_warning = "Text2Reg Warning:";
//find tracks
Track videoTrack = FindTopTrackOfType(MediaType.Video);
if (null == videoTrack))
{
MessageBox.Show(String.Format("No video track to export"),tk_error);
return; // Since there are no tracks to process
}
foreach (Track track in vegas.Project.Tracks)
{
try
{
// only the selected tracks
if (!track.Selected) continue;
foreach (TrackEvent trackEvent in track.Events)
{
Media media = trackEvent.ActiveTake.Media;
OFXEffect ofxEffect= media.Generator.OFXEffect;
OFXStringParameter txtparam = (OFXStringParameter) ofxEffect.FindParameterByName("Text");
RichTextBox rtfText = new RichTextBox();
rtfText.Rtf = txtparam.Value;
string MiniActiveTakeName = rtfText.Text;
if (MiniActiveTakeName == "")
{
if (MessageBox.Show("Some media contains no text.\r\nDo you want to continue?",
tk_warning, MessageBoxButtons.YesNo) == DialogResult.No)
{
vegas.Project.Regions.Clear();
return;
}
}
Region region = new Region(trackEvent.Start, trackEvent.Length, MiniActiveTakeName);
try
{
vegas.Project.Regions.Add(region);
}
catch (Exception e)
{
MessageBox.Show(String.Format("Couldn't place Region at {0}\nThe error message: {1}", trackEvent.Start.ToString(), e.Message));
}
}
}
catch (Exception e)
{
MessageBox.Show(String.Format("Selected track has no media text\r\nor some media text are in (Legacy) Text.", e.Message),tk_error);
vegas.Project.Regions.Clear();
return;
}
}
}
public Track FindTopTrackOfType(mediaType)
{
foreach (Track myTrack in myVegas.Project.Tracks)
{
if (myTrack.MediaType == mediaType)
{
return myTrack;
}
}
return null;
}
}
Many thanks. I tried ways to convert code from jscript to c sharp.
First script works. Second script gives me an error at this line:
"public Track FindTopTrackOfType(mediaType)"
SelectedTrackstoRegions3.cs(72) : Identifier expected
@playmarius, sorry about that. Change:
public Track FindTopTrackOfType(mediaType)
to:
public Track FindTopTrackOfType(MediaType mediaType)
You have to specify the variable types and I missed that one.
