Excel report generation

Hello,
I am looking for a simple solution to this simple problem:
I have generated an excel data file using LabVIEW Report Generation Toolkit for Microsoft Office ( see diagram below ).
Now I would like to add data to this worksheet every time I run this VI ( data must expand in column format instead of
row) but i have no Idea how to do it .
I would appreciate any help.
Thanks

That's what the start input is for. You tell it where to insert the cells.
Asides:
Why aren't you wiring the error out from the new report function to the next function?
Do not autoindex an array and wire a value to N. Do one or the other, not both. If you do both the loop will run for whichever value (N, or the array size) is smaller.
Your loop with the function node can be simplified by replacing it with a single Divide function and feeding the Divide function the arrays directly. The numeric functions (as well as many other functions) are polymorphic.

Time stamp to excel sheet

I want to print time stamp every second to an excel sheet, tried 1000 of times to add row to the sheet but failed, any clue how to?
Attachments:
time stamp in a row.vi ‏67 KB

That's because you're wiring the N value of the for-loop to the "column" element of the cell cluster, and you are wiring a constant of 1 to the "row" element of the cluster. You also have several issues with the code:
Do NOT hard-code a path the way you are doing. What will happen if someone else tries to run this code? What will happen if it runs on another computer that has Windows XP? Use a control and set it to a default value if you want.
No error handling whatsoever.
Do not use integer constants in lieu of enumerations. The VIs you are calling have parameters for which enumerations are provided. Use them. Right-click on the inputs and select Create->Constant. This will create the enumerations for you. They are self-documenting.
Do not have a time delay that cannot be bypassed if there is an error. You are running the loop 500 times. What will happen if there's an error on iteration 20? The loop still has to run 480 times, forcing you to wait 480 seconds before you can stop.
Be aware that timestamps between LabVIEW and Excel are different, since they use different epochs. This has been discussed ad nauseam in these forums, so do a search and you will find out how to deal with this.

How do I create this group of graphs?

Hi all. I am trying to create this block diagram for use in my project. However, I am new to labview and I do not know how many of the icons used here.
Can someone please help me with this? I would very much appreciate it.
Attachments:
intensity plot.png ‏206 KB

The best way to know what the icons are is to have the Context Help window open (Help -> Show Context Help). This will display a small window that will update as you move the cursor over VIs and functions, telling you what they are. If they are LabVIEW VIs/functions there will also be a link to the detailed help.
The VIs on the outside of the loop are two Sine Pattern VIs and the other is an Outer Product VI (linear algebra). The stuff inside is a couple of property nodes to get the position of the cursors. The mathematical functions should be obvious. Then you have a couple of Ramp Pattern VIs. Not sure what's inside the for loop. That might be a custom VI. See what the Context Help tells you.
If you have not already done so, I would recommend taking some tutorials.

How to give array of amplitutde input to the sinewave .vi

No, you cannot provide an array to that function. If you need to run the sweep for multiple amplitudes then you need to use a loop.

C# Constructor being called multiple times when I run my VI

Hi all,
We are runing LabVIEW 8.51 in the lab and have been using a bodged together C++ DLL which was crude but got the job done. Now looking at rewriting it in C# to make it easier to maintain and support long term.
Ive got the C# DLL appearing in Labview and can happily call my test functions from the VI to prove both the DLL inputs and outputs are working fine (the simple input a number, add 1 and return result type of code).
However, this DLL will end up managing a Serial port connection so the contstructor must only be called once as its responsible for making my .net serial port object. Ive added a text log message in the constructor and have found that just running the VI is causing the constructor to be called at least 5 times a second. There is no user input causing this....just running the VI.
Both VI and C# source is attached.
Any ideas folks? Im a complete newbie at LabVIEW having taken this on from another developer.
The VI is in \Release and this is where the Log file is generated.

How to insert an array of number in the array of cluster

hello, I have a question. How to put an array of numeric into an array of clusters which have different types of element?
Could you please show me in my vi?
Attachments:

It appears you didn't actually try anything. Have you done any LabVIEW tutorials? You can autoindex the array of clusters and use Bundle by Name. This assumes, of course, that the number of elements in the two arrays is the same. I would write it for you, but you will learn far more if you try it yourself first. If you don't know what autoindexing is, check the LabVIEW Help and the examples. Don't know what Bundle By Name is? Again, check the LabVIEW Help and the examples.

Software recommendation

I need to create a user interface software on a PC running Windows XP or Windows 7. The software needs to send and receive short data strings on a single RS232 port for controlling a custom RS232 instrument. The data strings are less than 10 bytes of ASCII and are not packetized with checksums. The user interface needs just a few soft buttons to send commands and a few windows to display voltage and current readings from the RS232 port. Click a button, see a reading.
I do not have software to write this application, still need to buy it. The software should be easy to learn and use so I spend less time trying to learn the software and get the job done quickly. I have no prior PC software writing experience but >30yrs in firmware. Might be crazy asking this question in a LabView forum but is LabView a good software to use for this? Any specific versions to look for?

That kind of depends on your definition of crazy...
Obviously, asking this in a LabVIEW forum will provide more positives than negatives. Since you have a background in firmware I'm guessing your background is with eihter C or assembly language. Given that, the programming paradigm in LabVIEW is not the same. LabVIEW is a dataflow language, not a procedural language, like text-based programming. Dataflow means a node executes when data is present - it doesn't matter whether it's to the left of another node, above it, or below it. A lot of people who start out in LabVIEW don't get this and they try to program LabVIEW as if it were C. C++ experts will tell you the same thing if you're starting in C++ and come from C: don't program C++ as if it were C.
If you were to purchase LabVIEW you'd get the most recent version, which is LabVIEW 2010. However, I think you might be asking about a specific edition, as in whether to get the Base, Full, Professional, or Developer Suite. I can tell you one thing here: don't get the Base. The Base does not include the event structure which you will almost certainly need. For RS-232 you would be using NI-VISA, which is a separate item, albeit it's free. Thus, the Full should suffice for what you're doing. NOTE: you did not indicate whether you are planning to build this into an application for distribution. If so, that requires the Application Builder. The Full edition does NOT include the Application Builder - you would need to buy that separately. The Professional Edition comes with the Application builder.
LabVIEW comes with a lot of examples (including ones for serial communication), and for what you're doing you'd best be served by using a standard programming design pattern, such as the state machine or the producer-consumer. For what you're doing a simple producer-consumer would be quite effective.
Your best bet to see if LabVIEW is right for you is to download the demo - you can use it for 30 days. Please note that the demo is the Professional edition. There are also tutorials available in the introduction material, and other material in the NI Developer Zone's Learning Center which provides links to other materials and other tutorials. You can also take the online courses for free.
Now, with all that said I would be remiss in saying that you can also do this quite easily with another development environment, such as C, or .NET. The big advantage with this method is that Microsoft makes available Express editions of their .NET development tools for free.
Ultimately, it comes down to what your budget is, and what you feel most comfortable in.

   My C++ code has many inputs and I am going to get different results ( pressure-temp-friction etc). I am looking at call library function and I couldnt add more than one "return type" . Do I need to name parameters like return type 1, 2, 3 etc... Do you have an idea, how can i get more than one return result?
A C function can have only one return value. This is a C limitation, not a LabVIEW limitation. What's sometimes done in this case is to have these additional values "returned" as function arguments. You pass in a pointer to a value of the appropriate data type, and the function will write the new value to that memory location. If you don't know what that means, then I'd suggest spending some time with C tutorials.
   Also, when i run my c++ code, I can get all results in a notepad file.... In labview when I run the dll, how can i create that kind of file in the computer to store my run's result?
As noted, you can use Write to Text File. Or, you can use Write Spreadsheet File to create a delimited text file that can be easily imported into a spreadsheet application such as Excel. Or, you can use the Write to Measurement File VI if you want extra formatting at the beginning.
   Thank you again, I am very beginner at Labview.....

Case structure

Hello!!
I have no longer started programming with labview and I'm having problems with a simple matter.
How can program the following?: "if two conditions are true simultaneously, a certain case of a case structure will be executed".
In my code, I would like a boolean to be true but also a numeric data to be 1, to execute that specific case.
How can I do so? What would I have at the input of the case structure?
Thank you very much in advance,
Miren

Your question is an extremely basic one. You're asking about Boolean functions and Comparison functions. Have you done any of the tutorials?

Note: if your "numeric" is floating point, DO NOT USE AN EQUAL FUNCTION, lest you wish to get bombarded on your next question asking why 1=1 can be false in LabVIEW. Do a search on comparing floats and you will understand.

Generating a digital signal

I am trying to generate a digital signal which can be controlled in terms time i.e. Switching ON for 10 minis off for 5 minutes. I tried to generate a digital signal which is going high but unable to control it. As I am the beginner in labview any kind of help is appreciated.

It appears that all you posted is one of the shipping examples. Is that all you've tried? You can't control it because you're not actually doing anything inside the loop. You're simply setting the value high before the loop starts, and not changing it in the loop. What kind of device do you have? Is it software controlled? If so, you will need to keep track of the time inside the loop. You can use the Elapsed Time VI to do this. Attached is a simple example to get you started to see how this can be done. I'm sure you can figure out how to integrate what you did and what I've shown you.

Establish connection between labview and Lantronix XPort Pro

Hi:
I am pretty new in this field. I just got into grad program, and I have been asked to establish a TCP/IP connection between Lantronix XPort Pro and labview 8.5. The goal is to get data from the server (Lantronix XPort Pro) and put them into labview and modify them, then I need to send modified data back into server.
The server has registered into local network wirelessly, it has IP 192.168.5.117 in port 26.
I would really appreciate your help and comments.
cheers!
Kian.

Which field are you "new" to? Programming in general? Programming in LabVIEW? TCP/IP?
Have you taken a look at the TCP/IP examples that ship with LabVIEW? There are simple Data Client/Data Server examples that show transfer of data over TCP/IP. You will likely need to do something very similar. Does the XPort Pro have a TCP/IP listener running? Do you have a communication protocol defined?
Also, if you are new the LabVIEW, have you gone through any of the tutorials?
