Topic: Dictionary Xrecord text CR removed on round trip

[Keith™]

Consider the following:
I have a text file that has ANSI encoding and I read it into a string in c#

Code - C#: [Select]

1. string data = FileSystem.ReadAllText(fn);

I don't do anything to the text except embed it into the drawing as dictionary data in an Xrecord

Code - C#: [Select]

1. ResultBuffer rb = new ResultBuffer(new TypedValue(DxfCode.Text, data));
2. Xrecord xr = new Xrecord();
3. xr.Data = rb;
4. acDict.SetAt(layout.handle, xr);
5. acTrans.AddNewlyCreatedDBObject(xr, true);
6. acTrans.Commit();

This works fine ... however when retrieving it and exporting it to a file it isn't formatted as it is in the source file.

Code - C#: [Select]

1. foreach (TypedValue tv in xr.Data)
2. {
3.     if (tv.TypedCode == DxfCode.Text)
4.     {
5.         data = tv.Value.ToString();
6.     }
7. }

So one of three things is happening
1) The CR isn't written to the Xrecord;
2) The CR isn't read from the Xrecord;
3) Something else?


To complicate things more, when I read the data into a textbox control, it shows correctly and can be copied and pasted to notepad correctly, but when saved it does not work.

I've investigated the WriteAllText function by opening a file and writing it to a temporary file and it works fine.

I'll entertain ideas  ... I could certainly parse the string and replace lf with crlf, but that just feels like a bug waiting to happen

Well damn .. according to the MS website, it is the control that strips all CRs from the text.

I guess its a replace function after all ...

Good to know Keith, thanks for the follow up.

If someone could figure out how to get the proper extended styles on the control, it could possibly be resolved.

According to MS if you set the SES_XLTCRCRLFTOCR flag it will not strip the CRLF, but I tried a dozen times and different ways to SendMessage that flag and it always fails.

have you tried using a RichTextBox control? These are designed for multiline text and reading/writing to/from file isn't a prolem AFAIK, cheers.

[Keith™]

Yep ... same issue
