log points into a _dat file

[Zoes]

Hi

Would like some help with "writing" points of workpart in a _dat file in real time. So far the code bellow exports the points to a file and then closes it. Can we use a File Mode to keep the file open and still write on it?

Code:
Dim outFile As IO.StreamWriter
outFile = My.Computer.FileSystem.OpenTextFileWriter("C:\test.txt", False)
outFile.AutoFlush = True
outFile.WriteLine(thisPoint.Coordinates.X.ToString("F6") & ", ")
outFile.Close()

Not that I'm aware of. As far as I know, the Close method writes the buffer (memory) to file and saves it. If you keep the file open, you will only write to memory (e.g. the StreamWriter).

I see...
What about loading them in dlg box? Can we have two or more dlg boxes open at the same time?

No (at least I don't think so). What are you trying to accomplish? There might be an easier way to reach your goal.

Track the history of changes of an expression_value or points of a workpart.
So that's the reason I want to keep a text file or dialog box open continuously and populate it with for e.g the updates of a tracked expession.


Ps: Can a dlg box open (push) another dlg box to open? What can't of code is required?

Thanks for the interest Marc.

Yes, this should be possible. However, as far as I know, these dialogs are modal (

http://en.wikipedia.org/wiki/Modal_window).

That means the user won't be able to continue until the dialog has been closed first.

What you want to do seems rather complex and could eat up a lot of performance. Do you want to track changes to certain expressions every time they change (n logs), or only those changes when the user opens a part, then saves it (2 logs)?

There might be a possible solution using certain callbacks, but this requires an extensive knowledge of NX and solid programming skills.

Yes I would like to track changes of certain expressions every time they change.

Then I might need to find a different way around it.
