How do I generate output with a certain conditional build expression?
Hi,
I am learning how to use conditional tags in RoboHelp 9. I see how to create and apply the tags. How do I apply the conditions in the output? And can I apply the conditions to the Web output and printed output?
I am going to be working on a project with variations to suit each customer, so I am wondering if RH 9 is a good tool to use for this. (I have access to XMetaL 5 also.)
Thanks,
Erin

How to cause a "Completed with errors" map condition?
Our application testers asked me how to replicate a "Completed with errors" map condition, so they can verify that our application reports and handles this correctly. I've been able to generate "Completed with warnings" (create records with duplicate keys) and "Failed" conditions (drop a source table), but not "Completed with errors". Anyone know of a way to produce this condition?
Thanks!
Steve LockeHi Steve
It depends on your 'Maximum Number of Errors' configuration property. By default this value is 50, so its highly likely you are running set based and you have used the default number of errors (50) and the error count after the run is 1 so you have the status completed with warnings. If you change the maximum number of errors to 0, you will complete with errors if there are any errors at all.
Cheers

How can I delete Conditional Build Expressions in RH7?
I have a project with some Conditional Build Expression artifacts that I simply cannot get rid of.
For example, I have created two Conditional Build Expressions:
Internal OR Foo1
Foo1 OR Foo2
It has been determined that the second expression is the one we want. But, the first one still shows up as an option in the SSL. Furthermore, when I view a page, the first expression clutters up my list of possible Conditional Build Expressions.
How can I lose a Conditional Build Expression? I have quite a few possible arrangements, and I don't want to confuse other authors by having too many choices (especially with similar names).
KevinHi Kevin.
I think you have to do this by manually editing the project's .pss file (projectname.pss). If you take a backup of this file and open it in Notepad you'll find a [Global Build Tag Expressions] section and hopefully in there will be your "Internal OR Foo1" expression preceded with a date/time stamp. If you remove this line it should no longer appear in your project.

How can we generate javadocs with Jdev3
Hello,
I'm using JDeveloper3 to create some javabeans. I don't know how I can generate javadocs from JDeveloper3 with JDK1.2.2
NicolasWith this information I don't think, that the 7334 is the right board for your application. The 7334 is a motion control board for stepper motors. As control signals it provides a step signal with variable frequency and a direction signal (high or low for fwd. or rev. direction). The step signal is generated onboard and controls the motor's trajectory (acceleration, velocity, travel distance). The duty cycle of this signal can't be changed by the control program, so this signal can't be used for your application.
The PWM outputs provided by the 7334 is static. That means, you can set frequency and duty cycle only in software, which is quite slow and introduces significant and non-deterministic jitter (due to the asynchronous communication to the 7334 this is even true if you are using a real-time operating system). These limitations don't seem to meet your requirements.
I still don't have a good idea about your timing requirements. If your response times requirments are in the upper milisecond regions (10 ms and above), you might be able to use the 7334. If low jitter and fast response times are important to your application, there are several alternative solutions including LabVIEW Real-Time with a multifunction data acquisition board and LabVIEW FPGA with an R-Series board.

RH6 crashes with th and conditional build tags
Hello together,
The attached code worked fine with RH X5, but leads to a
crash with X6. To fix, you have to replace the <th> by
<td>, but it is not too easy to find the topic within a
project. The fix is quite easy, but it is hard to find in a big
project.
This happens, when the conditional build tag is used.
Thanks and best regards,
Katrin LusserHello Peter,
My wife created the topic with X3 or X5.
She just tried again with X6 and after several changes (set
heading, insert, delete, etc.) she had the same constellation.
Unfortunately, until now, she could not find out the exact way to
reproduce. But it is definitely possible. We will post here, when
we find out, how to do it.
Best regards,

Help with conditional build expressions
I'm using RoboHelp HTML and creating WebHelp Pro layouts. I
want to create five (or more) different versions of the Help tool
for our various groups of users.
Here's what I'd like to do: Create a conditional build tag
for each of the versions (i.e. each of our groups of users). I
could name them as follows:
group1
group2
group3
group4
group5
Then, I would associate each topic with one or more of the
build tags. For example, topic1 may be for group1 and group2;
topic2 may be for group1 and group4. Etc.
The problem is thus: When I want to create the version for,
say, group1, my expression ends up excluding the other groups. In
the end, this omits any topics associated with group1 that are also
associated with the other build tags (i.e. the other groups).
Is there an expression I can use to prevent these topics from
being omitted? Perhaps the use of parentheses?
The only solution I've used is tedious: I create many build
tags--one for each variation. For example, I'd have a
group1group2group3 build tag, a group1group3 build tag, a
group1group4 build tag, etc. Then, I just associate one build tag
with each topic. When I'm creating a version for group1, for
example, I'd just include all topics with a build tag that includes
group1 (e.g. group1, group1group3, group1group2group3, et. al.). I
omit the others (e.g. group2group3, group2group4,
group2group3group4group5...et. al.).
As you can imagine, this solution is problematic. First, I
have to create and keep track of many many build tags. Then, if I
want to create another version of Help, I need to change all the
build tags to include this new group.
I'm sure there must be a better build tag expression for what
I'm trying to accomplish. Please help! Thanks!There is indeed an expression! Unfortunately, the option is
normally hidden, so it can be tricky to find. Here's what you do:
1. Define the build tags.
2. Apply them to your topics. OVERLAPPING IS ENCOURAGED! That
is to say, you can assign tag1, tag2, and tag3 to a single topic.
3. Right-click the desired layout and select Properties.
4. Click the Define button to the right of the Conditional
Build Tag drop-down menu. The Define Conditional Build Tag
Expression dialog will appear.
5. Click the Advanced button. The Advanced area will appear
at the bottom of the dialog.
6. Select a tag from the Available Conditional Build Tags
drop-down menu.
7. Click the Add Tag button. The selected tag will appear in
the Conditional Build Tag Expression display window.
8. Click the AND button.
9. Select another tag from the drop-down menu.
10. Click the Add Tag button.
11. Repeat steps 8-10 for each tag you wish to add to the
expression.
12. Click the OK button to close the dialog.
13. Click the Save button to save your layout with the new
build expression.
That's it! The trick is to use the ADVANCED button in the
Define Conditional Build Tag Expression dialog. Doing so allows you
to build inclusional expressions rather than exclusional
expressions, so you can avoid the hassle you described in your
post. Using this method, I defined two build tags (A and B) and
applied them to three topics as follows:
* Topic 1: Tag A
* Topic 2: Tag B
* Topic 3: Tags A and B
I then defined an expression that simply included tag A. When
I compiled my help, topics 1 and 3 appeared in the output, but
topic 2 did not. -
How can I generate tones with usb 6008 using analog out?... tia sal2
Greetings All
I've been looking at the example Sim Phone.vi that comes with labview and would like to generate similar tones out of our usb 6008 device. I can get a very faint sound out of our usb 6008 using the example Gen Multi Volt Updates-SW Timed.vi Does anyone know the best way to alter Sim Phone.vi to have the sound come out of the Analog output of our usb 6008 device. ( I have a small speaker connected to the Analog out on our USB 6008)
PS: we are using labview 7.1
Does anyone know the Analog output frequency range of the usb-6008? Is this possible?
TIA

Gen Mult Volt Updates-SW Timed.vi 78 KBHi sal2,
As stated earlier you could most certainly use the USB device to generate sound, but that would be at a max update rate of 150 Hz. While according to Nyquist theorem you could get frequency information for signals below 75 Hz, you may notice that the quality of the data in that spectrum to be very low due to having so few samples.
While technically possible to produce you really should look for a device with a faster Analog Output update rate. I would look for a device that supports Analog Output at least 10x the maximum frequency that you want the user to hear. Some great, yet lower cost products, would be the M-Series line of products. They would give you the performance that is really needed in the type of application that you are talking about.
If you still want to use the USB Device, then you would need to use code similar to that found in the example Gen Mult Volt Updates-SW Timed (Found here: C:\Program Files\National Instruments\LabVIEW 7.1\examples\daqmxbase\Dynamic\ao).
Best of luck getting your system together,

How to use java output with other application
hi ,
I am using acme.crypto to encrypt data. this is completely written in java. i need to pass input to this using VB6 and return the output to VB6
how can i achieve the same, is there any readily available dll that can be used in vb?
I am rigorously searching solution, which i am not finding.
I need to know how should i place the java code so that it could be used with VB, as i am new to java world. Do i need to create component using java bean or how?
The code i refered above is nothing but encryption algorithm. I need to pass the input string from vb to java, which will process me the output which inturn should be passed to vb6.
Kindly guide me through this.Why not create a Java ServerSocket in your Java program.
Connect the VB program to this ServerSocket.
Send the input to the Java Program over this socket and have the Java Program encrypt the information and pass it back on the same socket.
Don't know how hard Sockets are in VB6 but a Server Socket in Java is simple.
No need for new DLLs, JNI, etc. -
How do I generate URL with multiple variables from input fields?
I'm creating an ad with four input text fields labels fname, lname, city and prov, and I wanted to know how to generate URLs based on information entered into the fields. The text fields default to display "First Name," "Last Name," "City" and "State," respectively, but if a user does not enter information in those fields, I want the URL to behave as if those were empty, if that makes sense. The text fields are in a movie clip called "input_text" and the button is labeled "send". If any of you can provide insight, I would be greatly appreciative. Thank you.
1. use if-statements to see if the text properties of your textfields meets your requirements for creating that url.
2. you can use the flash string methods and properties to create your url.
p.s. the plus sign + can be used to concatenate strings. -
How do I generate formula with column of text?
I have a list of attendees to an upcoming party. Three columns - First Name, Last Name, Attendance.
In the "Attendance" column I have created drop down menues with 4 different text values regarding their attendance (Yes, No, Maybe, No Reply).
At the top of the page I would like to have a quick list table referencing the text values and count; would look like this:
Yes - 34
No - 12
Maybe - 24
No Reply - 13
How do I create this quick list with number count since the values in the "Attendance" column are text.
Thank you kindly!Okay hotshot, I'm stuck again.
Now I want to gather the number of "Yeses" from two different tables. This is what I have tried so far but am stuck: =COUNTIF(Terry Allen :: Attendance,Ron Allen :: Attendance,"Yes")
There error message I received was "Countif requires 2 arguments, but was given 3."
I do have a way around it; just use your previous formula to tally up the number of yeses at the bottom of each table, and then sum it all up, but I would rather just cut to the chase and have it formulate directly in my quick list table at the top of the page.
Any thoughts? Thanks.

How to override generated WSDL with existing WSDL file?
Hi there,
I am migrating our weblogic 8.1 web services to weblogic 10.1. As documented it is not possible to start implementing the web services from WSDL if the web services are based on XML Beans. Therefore I started from scratch, using an XML Beans Utility project and a web service started from Java. This works fine.
I now have a web service with a generated WSDL file, but there are slight differences with the existing WSDL file.
Is it possible to stop generating the WSDL file and just point to the existing WSDL files?
I already tried to expose the WSDL and change the WSDL location but it still returns the generated WSDL instead of the WSDL file that I want.
Thanks in advance,

How use video generator ni5431 with visual c++
i use a ni5431 video generator with visual c++.
i generate a ccir signal and i want to modify attributes IMAGE_TOP, IMAGE_HEIGHT and IMAGE_WIDTH. When i change one of these attribute with VDG_SetAttribute(****,int) i can't obtain a signal.
Thank you for your help.Proably the reason this question has gone so long without an answer is that the Vision forum only covers our NI Image Acquisition hardware (along with all NI Vision software), and not our signal generator hardware. That hardware is covered in the Signal Sources forum under the Measurment Hardware section, which is serviced by a different set of Enthusiasts and experts. If you ask your questions there, you should get a quick response.
