Could someone help me in solving this
Thanks

Hi smercurio_fc
Thanks for the vi. i tried the method which you have sent me.
So i cant transfer 'S' through serial port?
Is there any other way to transmit this through Serial port.
Also i need another clarification
A sub vi is running inside my main vi and i need to stop/pause the sub vi from the main vi front panel. how could i can stop the sub vi?
Thanks and regards

Hex String to 'Ascii Hex' String!

I am having a mental block and wonder if someone can help!!
I am reading a serial device and getting a hex string back. I need to display this hex string to the operator within a pop-up box (PDA). The Message box will obviously contain normal text with the HEX code appended to the bottom.
When I run the code the pop-up box displays the legible message to the user but the HEX string returned appears in the appropriatte ascii characters (because the pop-up displays normal string).
My question is, how to make an hex string appear within a normal display string indicator 'the same' as it appears in its Hex display indicator:
0x0A1C - Hex display needs to appear as 0A1C in normal display string indicator.
Thanks in advance

Hex string and normal string concatenate issue

Hello,
what i have is a hex string and a normal string which i want to concatenate into one string. the problem is that in the output concatenated string you need to select either "normal display" or "hex display" in the properties. the problem is if you select hex display then the normal string is converted into hex and if you select normal display then the hex value is not correct. is there a way to display the hex value in normal display mode?
attached is a vi showing the problem

If by "correct output", you mean you want something like 4bytes (0xBADDF00D) converted to 8bytes ("BADDF00D" in normal display), then there are several ways ...

This is the program where u can get the WA_THEAD from other program like report and trying to display and modifying that text. U can do instead of WA_THEAD u can generate here itself and use also

JTable -showing column headers and displaying multi-line strings

Hi,
This is two questions really.
#1 - Does anyone know why my column headers aren't showing in my jtable using the model below?
#2 - Does anyone know how I can display, mulitple line strings in a jtable? Currently my newline character ('\n') is just being displayed as a character.
any help very much appreciated,

this string will appear on two lines in a jtable

Turn a string that shows hex data in normal format, into a string that shows the same data in hex format

I have a string of arbitrary length - say, 1AB1C0 - in normal format. I would like to have a function which takes that string in, and outputs the same exact characters, but in hex format. So the input will read 1AB1C0 in normal string format, and the output will read 1AB1C0 in hex string format.
I am doing this because I have found the end device works better if I send the bytes as a hex string vs. as an array of U8. Furthermore, I manipulate a lot of byte streams in my program, and I find the string parsing tools less cumbersome to use vs. the byte array parsing tools - however, they only work on the strings as they appear in normal mode. So I have reasons in different parts of my program to have the string in normal vs. hex formats; but I cannot figure out any remotely elegant way to cast from one to the other.
Solved!

Well, you need to scan the hex formatted string two bytes at a time to an U8 numeric and then cast it back to a string. There are many ways to do that, here are two possibilities. (Mkae sure to use the correct representations as labeled).
(I still don't quite understand your reasoning why you need this).

GP - How to display a long string value

I'm trying to display a really long string value and then allow the user a couple of result state choices (to either go back and do another search or finish).
None of the forms (WD, display, etc.) will display a really long string.
I tried using a loop type decision dialog, but there doesn't appear to be a way of having it pick up a parameter value as the message (or part of the message) to display.
I can get it to display in the complex type decision dialog, but I don't need the group/options and I can't seem to get rid of the second set of buttons that show up (the long string parameter value was put into the 'Info Texts' area and does display ok).
Is there any easy way of displaying the complete contents of a long string value and have buttons for results states? I'd even be happy if I could just display the whole string and use a separate callable object for the choices.
Thanks,
Cindy

I think you should try calling a JAVA or ABAP Webdynpro as the callable object. As you know, we can display long texts in the webdynpro fields. Other alternative is an Adobe form as well.

How to display a HTML String in a ActiveX WebBrowser ?

How to direct display a HTML String in a ActiveX WebBrowser without use a URL ?

I am sure that it would depend on the browser, but with Internet Explorer from Microsoft, I don't think you can. (I may be wrong on this.) What you could do would be to save your string to file and read the file as a url in the browser. I know that this is a step you are trying to avoid, but it will work.
Hope that this helps,

How to embed a browser displaying an xml string in a tab

Hi,
I have an xml string which i need to display it in a browser.
But the browser should be embedded in one of the tabs of a tabstrip ui control and not as a pop up.
Thanks in advace,
ajay

hi alex,
I need to display the xml output in one of the tabs of a tab strip control.The output should be displayed in the same format like the way it would be displayed in the browser.
Since it was mentioned in your previous post that it is not possible to embed the browser in a tab, is there a alternative way to display the same.
thanks and regards,
ajay

I want to communicate a RS485/2-wire device through COM1. I tried Instrument I/O Assistance to write to COM1(hex string with or without end bye:0D0A), something happened on the bus, but is not defirrential signal, and device didn't recognised them.

I am new to LabView, so please bear with me...
I tried to communicate with an RS485/2-wire device through COM1. I used Instrument I/O Assistant (and Advanced/Basic Serial Write and Read examples) to write command (HEX string) to COM1,
tried writing HEX strings with and withour end bye (is 0D0A the correct end signal for HEX string?). Both didn't get device's responce. Looks like the device didn't recognize the command.
I monitored the transmitted signals on the bus, they were not differential as supposed to be.....
What is the possible reason to cause this? Please help...
The hardware connection is OK, because I am able to communicate with the device through COM1 (with the same command) using different software application.

How are you sending the hex? Is your string control set for hex display or normal? If it's set for normal, then if you send something like 'AD', then you aer sending the ASCII characters 'A' and 'D' and that's not the same thing. I don't believe the I/O assistant can send hex but you can modify the basic serial write and read to do so. Just right click on the string control and select 'Hex Display'. You can also enter the data in a numeric control (set for dex display) and use a type cast or an array of U8's and use the Byte Array to String function. Hex data usually doesn't use any kind of termination characters such as CR/LF.
If communication is working with another app, then as you said, the hardware is okay and it's not a problem with differential signaling.

Convers ascii string to hex string

I need to send a hex string such as 5051525354A5A6A7A8A9 to a DSP across a serial port. The string is read in from a file.
When I send this string to the DSP, it does not recognize the correct hex values.
If I enter the hex value, 5051525354A5A6A7A8A9, in to a string control that is set to hex display and then change the control to normal display, I get PQRST¥¦§¨©. When I send this string, PQRST¥¦§¨©, to the DSP, it recognizes the correct hex values.
How can I change the hex string read from the text file to this type of ASCII character conversion? I've used type cast and the other functions available in LabVIEW with no success.
This is only one of many strings I need to send so I don't want to hard code PQRST¥¦§¨© or some such string for each message.

Here's a slightly simpler way.

How to convert hex string to time stamp?

Hello everyone..
I am currently working on a project in which I have to read the data from a unit and display that data using LabVIEW. I am using serial communication for reading the data. The read data is in hex format.
Now, I want to convert this hex string to a time stamp value. I am reading total 16 bytes. How to convert this hex data to a time stamp value. I have developed a VI. But I want to know that the displayed time stamp is correct or not? Or suggest me some other solution.
I am using LabVIEW 2011.
Thanks & Regards,
Manisha
