How to write attributes to a .stp file in Adobe 3D Reviewer?

Hello All,
I am trying to import a .stp file into Adobe 3D Reviewer and I need to write attributes to this file. I am using VB (.NET 4.0) for this purpose.
I imported the Adobe 3D Reviewer Object Library reference and am trying to make use of the AddAttribute method of the GeomItem class to write the attributes. However, I am unable to instantiate the GeomItem class. I get this error : 'Adobe3DReviewer.GeomItemClass.Friend Sub New()' is not accessible in this context because it is 'Friend'. I am not sure how else can I access this class? Also, in the object browser GeomItem shows up as a class but in Intellisense it shows up as an interface.
Can anyone shed some light on how to resolve this error or make use of any other method to write the attributes and their values in the Adobe 3D Reviewer? Also, if anyone can point to some documentation related to this stuff it would be great!
Thanks in advance.

  • How to write data to an XML file present under application server

    frnds: can ne one tell me, how to write data in to a file, which is present under a application server
    Ex: i want to write a string data in to a file test.txt which is present under "http://localhost:8080/<some_webapp>/test.txt"
    Note:i have deploted a service<some_webapp> under Tomcat/webapps dir

    Very simple. A servlet can writes to that file if it has the good rights.
    In the servlet get (or post) method, use a code like this:
    import java.io.*;
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) {
    try {
    String filePath = this.getServletContext().getRealPath("/text.txt");//See http://java.sun.com/products/servlet/2.2/javadoc/javax/servlet/ServletContext.html#getRealPath(java.lang.String)
             PrintWriter writer = new PrintWriter (filePath);
            //or BufferedWriter out = new BufferedWriter(new FileWriter(filePath));
            writer .println("aString");
           writer.flush();
            writer .close();
        } catch (Exception e) {
           e.printStackTrace();
    }Hope That Helps

  • How to write new line to a File?

    How to write new line to a file?
    I have a string to be written to a file. the string contains "\n" in it. But why it is not showing the new line in the file.
    I have tryed FileWriter class and FileOutputStream class, but none of them works?
    any suggestion please...

    Probably using PrintStream::println() is a portable way.
    import java.io.FileOutputStream;
    import java.io.PrintStream;
    public class NewLine {
        public static void main(String[] args) {
         try {
             PrintStream ps = new PrintStream(new FileOutputStream("foo.txt"));
             ps.write("string".getBytes());
             ps.println();
             ps.close();
         } catch (java.io.IOException e) {
             e.printStackTrace();
    }Regards,

    How can I reprint a large # of files in adobe acrobat XI since there's no batch processing feature?

    One of the available commands in the Action Wizard is Print (under the More
    Tools sub-section). You create a new Action, add that command and then run
    it on your files to print them all.

    how can i edit a scanned pdf file in adobe acrobae 9 pro ?

    With Clear Scan you get the text replacing the graphics of text. That can be edited. If you do searchable PDF conversion, you can still edit (I think). However it is an edit of the hidden layer of text behind the graphic and does not show on screen normally.
    Usually the best choice is to ask the author for the original file to edit. If that is a copyright issue, then you should not be editing anyway.

  • How do I transfer a SODA PDF file to ADOBE PDF?

    How do I transfer a SODA PDF file to ADOBE PDF?

    In ways, a pdf is a pdf. Adobe pdf files tend to be the most compliant to pdf standards.
    I guess my question is, why do you need to do that? Either the pdf is compliant and works fine or, it doesn't. If it's a bad pdf it will be bad no matter what you do (short of recreating it from the original file).

  • How do I open a new original file on adobe

    How do I open a new original file on adobe, and how do I merge exiting files under one title.

    The iOS reader doesn't create pdfs. Adobe does sell a CreatePDF app.
    The iOS reader does not merge pdfs any more than the Reader for Mac or PC. I cannot find any reference to the CreatePDF merging two different pdfs.
    Adobe does a have a web createpdf service that does combine pdfs into one pdf (createpdf.acrobat.com), but I doubt it would work from an iOS device. But you could ask the the acrobat.com forum.

  • How continuously write data to a txt file

    hello, 
    first of all, sorry for bad English, but I have a problem to continuously write data to the txt file.... I have one 2D array with values of some function and based on 2 sliders (values of the sliders) i want to interpolate value using bilinear method... and after that value of the sliders, interpolated value, and value of the nearest points i wish to write to txt file ... for every 2-3 seconds perhaps it would be ideal to be formated as :: 
    x   y   f     f1   f2   f3   f4
    but... first i have problem with writing data, because every time it deletes old data and just write new one and it's not horizontal... I'm very very new at this (it is obvious) and any help will be very appreciative  
    thanks

    Hi there,
    May I suggest you start with the LabVIEW tutorial?  Or perhaps this one?
    I say that because 1) you said you're new at this, and these tutorials are great for getting started; and 2) you don't seem to understand the concept of dataflow.
    A structure, such as a loop or subVI or function, cannot start executing until it has all of its inputs available.  Therefore, the loop which contains your file write (bottom loop) cannot execute until your top loop is done executing, because it depends on inputs from your top loop and those inputs aren't available until the top loop is finished.  Thus, your file will contain only the data from your final top loop execution.  You might be thinking that your loops are executing in parallel.  They are not.  Your file loop is executing after your data loop has finished...that is to say, your file loop executes exactly once, after you press your stop button.
    You can do two things here to fix that:
    1.  You can move your file write into the top (data) loop. (probably easier for now)
    2.  You can use a queue to transfer the data from your top (data) loop into your bottom (file write) loop. (more complex, but a better idea in the long run)
    One other thing.  Move the "open file" function outside the loop.  Opening and closing the file in each loop iteration will cause problems.  Open the file once.  Write to it in each loop iteration.  Close it when you're done.  Like this:
    Note that this is not complete code...you need to provide the data to write.  This is just to show you how to set up a continuous file write.
    Ok, start with the tutorials and we'll go from there. 

  • How read/write matlab style WAV sound file?

    The supplied LabVIEW WAV read/write VIs require fixed sampling rates (like 8000, 11025, 22050, 44100), and use integer data (so the waveforms take on large +/- integer values).
    I need to read/write WAV files that are like those used in Matlab with its wavread and wavwrite functions. Those can use ANY sample rate, and the waveforms have decimal values between -1 and +1.
    Could someone suggest either how to directly write these standard WAV files with an existing VI, or how to write my own VI to do this?
    Thanks in advance.

    That's a great help! Thanks. I have made the changes to the supplied NI VIs so that any rate can be used. The new read/write VIs are attached and seem to work ok.
    Best,
    F
