Multiple document merge : AccessViolationException

[MasterOfPandas]

Hi,

First, sorry for my bad english , i'm french. I post because i have problem with merging multiple document. When i add documents to ServerTextControl.Selection, i catch an AccessViolationException.


code :

WordFile word = new WordFile(new ServerTextControl());
            word.stc.Create();
            foreach (String path in pathList)
            {
                word.stc.Selection.Load(path, GetFormat(path));
                if (word == null)
                {
                    word = LoadFile(path);
                }
                else
                {
                    word.stc.Selection.Load(path, GetFormat(path));
                }
                File.Delete(path); // on supprime les fichiers temporaires crées
            }

WordFile Class just encapsulates (not sur of this word...) the ServerTextControl. When i add the new document to the current one, .Net throw a AccessViolationException, "you are trying to access not allowed memory" or something like this.

Process : In this application, users can check documents and download a merged document resulting of the merging of selected documents.

So multiple documents merging does not working, whereas single generation is working.

I don't know how i can fix this. I hope i was clear and understandable.

Thanks

Hello there,
Do you want to append or insert a document?
To append a document, please test the Append method.

Hello, thanks for reply.


I want to append one or several documents to a single one. I try to use the "Append Method", but with the same results...


I believe i'm using the same methods which is described in documentation.

Step 6: Merge Multiple Documents
This sample shows how to append several documents to TX Text Control .NET Server. The Load method can be used to load a document which replaces the current document in TX Text Control .NET Server. If a document should be appended or should replace the current Selection, the Selection.Load method must be used.

In this sample, 3 different documents will be loaded and saved as one merged document. The following loop loads all documents whose filenames are stored in an array list:

[C#]
foreach(string document in mergeDocs)
{
  TXTextControl.StreamType streamType = new TXTextControl.StreamType();
  if (document.EndsWith("doc"))
    streamType = TXTextControl.StreamType.MSWord;
  else if (document.EndsWith("rtf"))
    streamType = TXTextControl.StreamType.RichTextFormat;
  else if (document.EndsWith("htm"))
    streamType = TXTextControl.StreamType.HTMLFormat;
  try
  {
    serverTextControl1.Selection.Load(Server.MapPath(document), streamType);
  }
  catch(Exception ex)
  {
    Response.Write("<font color=red><b>An error has occurred:</b><br>");
    Response.Write(ex.ToString() + "</font>");
    return;
  }
  counter++;
  if(CheckBox1.Checked == true &&A counter != mergeDocs.Count)
  {
    serverTextControl1.Selection.Text = "\n\f\n";
  }
}

I do not see the Append method in your code.
Which version are you currently using?
Also, do you see any chance to reproduce your issue outside of your main project in another simple sample?
