How to detect a serial printer programmatically?

I have a serial printer connected to COM Port.
Is it possible to check if it is connected, programmatically?
I tried 'VISA find resources' function, but it always lists the COM port whether the printer is connected or not.

Most likely not easily!
LabVIEW can not access the printer since its port is likely already reserved/opened by the printer driver. VISA actually has a specific error code for ports that are normally opened by another process but the error message is a little unspecific. But most likely the printer driver has reserved the port in some non-standard way and VISA then gets some unexpected error because of that.
And the Windows API doesn't have a simple way to query the state of a printer other than if it is installed or not. An involved way may work, using EnumPrinters() requesting for PRINTER_INFO_2 data and checking the Status element in every returned printer record for the PRINTER_STATUS_OFFLINE flag, but that API doesn't count as easy to interface with the Call Library Node.

How to detect the serial cable been unplugged

Hi all,
I wrote a small application using the javax.comm api to talk to an external device. I would like to know how to detect if the cable is unplugged. Right now, if I run the application with cable not connected, if i start communicate with the device, the program will hang.
The program works fine with connection is there.
Please help me.

there are ways that do what he wants to do (though not what he says he wants to do), but they need to be implemented in hardware.
You could monitor the voltage on some of the pins on the serial connection for example, which tells you whether there's a signal on the line.
That of course would not detect whether the cable is there, as it has preconditions. It detects whether there's a signal on the cable, which requires that the systems on both ends of the cable are powered up and that the cable itself is not faulty.

How can detect the serial port is active

I made a program. It can read datas via serial port. But the datas wont came all the time, so the other part of the program not need to run. I want to put before the "reading serial port" a detection about the serial port is get a data. So the reading is wont start before datas are not coming. Can anybody help me how can i solve this problem?

Hi Zoyo, if you use the VISA- VIs, the functionyou need is "VISA Bytes at serial port". It shows, how many Bytes are available in the input buffer. You can find it here:

How to add a local serial printer with vbscript

For a new application that we are rolling out I need to add several printers to about 100 Windows XP workstations. Two of them are network printers and fairly easy to add using vbscript. The one I am having problems with is a locally attached serial printer. I am not really sure where to start for creating the port. I need it to use COM1 (4800, 8, none, 1) with the Generic / Text Only driver. Any ideas how to get started on this?

For future wonderers:
Cscript %WINDIR%\System32\Printing_Admin_Scripts\en-US\Prnmngr.vbs -a -p "COM PRINTER" -m "Generic / Text Only" -r COM1:

How do I change my printer settings programmatically ?

How do I open a print menu, to change the printer, the orientation and the number of pages to be printed out during the execution of a LabVIEW program ?

Check out the example at:
http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B45EACE3DFC656A4E034080020E74861&p_node=DZ52084&p_submitted=N&p_rank=&p_answer=&p_source=External
If you set the VI to display the printer dialog you can set the printer and the print orientation from there...the number of pages should be possible to control from what you actually put in the VI to be printed.

How to use AVDocPrintPagesWithParams for printing without any prompt dialog or alert message ?

Hi Friends,
I have a problem to print the pages of a pdf, but with out any dialog box prompt. So I choosed the api AVDocPrintPagesWithParams(avDoc, avDocPrintParam);
But I don't know how to set parameter for 2nd parameter of the funtion. My requirement is I want to print pdf's using default printer of the system i.e. Print As PDF using Abode PDF print.
Page Dimension should be same as previous, with postscript value 3 (best print).
I have used AVDocPrintPages (AVDoc doc, ASInt32 firstPage,ASInt32 lastPage, ASInt32 psLevel, ASBool binaryOK,ASBool shrinkToFit); But it gives an error message for some pdf's that PDF may not printed correctly because font information couldn't be found.
So can anyone let me know please how to set the parameter of AVDocPrintParam, so that I can use AVDocPrintPagesWithParams and do the same job.
Thanks and Regards,
Saffiuddin Sheikh.

Dear lrosenth,
I am into an operation where I have check whether each objects falls inside my rectangular region or not. For this I am taking help of BBox and matrix information. The problem is that when I find PDF's those have form or container objects, their matrix and BBox is depenedent on matirx of the form or container containing them.
In most cases by adding(concetinating ) the matrix value of form and the element gives the correct matrix, BBox value, but some cases I am yet to understand the behaviours. So to avoid these form and container for our immidiate project delivery, we are using this option to print the pdf and then process for checking the position of elements.
My original requirement is :
How to know objects position inside a form or container ?
This is just an alternative time being way to achieve the task. But if you have any idea of how to detect postion of objects inside form/container then please let me know.

How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

How to find ThinkPad serial number if label is worn?

QuestionI'm having some trouble with my T500 ThinkPad and want to contact service, but am not sure how I can find out the machine type and serial number to provide to support when I call because the sticker on the bottom of the laptop is faded so I don't know what the S/N is. I do have one number though: [serial removed] was what I copied down from it before it became faded. I dont know what to do now, so if you have any ideas, that'd be great.
Answer
Generally the label with type and serial information is found on the bottom of laptops and tablets and on the rear of desktop systems and on the back or along the edge of displays. As noted by the question asked above, in some cases, the label may become worn. To reduce / avoid this, the type / serial label was relocated to the battery compartment on some systems with removable batteries, along with the Win 7 COA. As Win 8 does not have a COA lable, and print technologies for labels have improved, most current systems have the label on the bottom.
Some tablets may have the type and serial information label on the inside of memory door / SD card slot covers as was the case with the ThinkPad tablet type 1838/1839.
Here is a link to an article on the support site with examples of label locations for different model Lenovo systems. If the system will not power up at all, finding the physical label is the best course of action when contacting service.
If the label is missing and the system will power up, there are several ways to easily find this information as it is written into the BIOS on the system board.
1) Command Prompt
Run an elevated command prompt, Enter the command "wmic bios get serialnumber" (without the quotations).
2) BIOS
Boot to BIOS (press F1 on startup) and the model type and serial number will be listed.
3) Diagnostics - Lenovo Solution Center (LSC) or the prior Lenovo ThinkVantage toolbox.

wmic bios get serialnumber does not work !!!!all your pages about how to find a serial number are disfunctuional !!! What a bed service

How to detect session objects in a project

Hi,
There are many session objects in our project which has over 1000 classes. What would you suggest as the best practice to identify all of them. I am using eclipse. How to detect they are serialized or not. If not serialized how could i make sure they are serializable or not.?
Appreciate your time.
Pralav

If not serialized how could i make sure they are serializable or not.?By implementing the Serializable interface.
If you want to ensure they can't be serialised, then you implement Externalisable and throw exceptions when you override readExternal() and writeExternal()
As for identifying the objects that are added to a session.... do a search for things like session.setAttribute() on your code. No easy way.

Owen

Detecting an installed printer-driver with jdk 1.3

Hi all,
is there anybody who knows how to detect all installed printers and how to figure out which printer is choosen by user? I can not find anything about this topic...
Thank you in advance - netti

John,
In the case of the R800, 3.0 has been around for about one year. However, 3.09 was first posted to Epson Europe on 29 October 07 and 6 November 07 to Epson Oceania (Australia and New Zealand). The driver is supposed to be fully compatible with Leopard, but I have no way of checking. According to both Europe and Oceania, drivers for the remaining R series printers (1800, 1900 and 2400) are due out later this month.

Hi,
As of now, the ePrint feature is not supported for your printer.
you may find the supported printers listed below:

How to disable HP Universal Printing dialog box

Hi, I am trying to install HP Universal Printing PCl 6 printers on a local machine using a batchfile from an application (C#) which automatically detects if a printer has been installed or not. The batchfile has the following entries:
set IP=IP_%1
pushd "%windir%\System32\Printing_Admin_Scripts\en-US\
Cscript Prnport.vbs -a -r IP -h %1
rundll32 printui.dll,PrintUIEntry /ia /m "HP Universal Printing PCl 6" /h "x64" /v "Type 3" /f %windir%\inf\ntprint.inf /u
rundll32 printui.dll,PrintUIEntry /if /b %1 /f "%windir%\inf\ntprint.inf" /r IP /m "HP Universal Printing PCl 6"
When I run my application, the printer is installed but when I try to print, sometimes I get the HP Universal Printing dialog asking me to select a printer. I can't even exit from this dialog. Other times when I dont get the printing dialog my print function fails with Invalid Handle exception.
The next time I try to print with the printer installed, it prints documents successfully.
How can I disable this print dialog using the batchfile above and why do I get the Invalid Handle expection on the first install and print??

I don't think there's anyway to disable it, I just minimise iTunes or click on another application's logo while it loads. I agree with you as to it being annoying, but I don't think there's anyway to disable it. In my opinion it should just do it in the background without the dialog box...!

Server Error (circular reference detected while serializing: )

Hi,
I just installed OC4J and it looks great. I have a problem however ...
I used JBuilder to generate entity beans from database. Then I generated a session bean with facade methods, and finally I created a session bean which injects the facade and is annotated with @WebService to publish a method (so that I could test the entity).
However, when trying to run findAllEmployees() I get this error returned:
<?xml version="1.0" encoding="UTF-8"?>
<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns0="http://logic.porter.xait.no/" xmlns:ns1="http://www.oracle.com/webservices/internal/literal"><env:Body><env:Fault><faultcode>env:Server</faultcode><faultstring>Internal Server Error (circular reference detected while serializing: no.bie.persistence.Employee)</faultstring></env:Fault></env:Body></env:Envelope>
I suspect this has something to do with the relationships between tables (@OneToMany etc.) -- but does anyone have more information on what would cause this problem and how to fix it?
Thanks!

Hei Guys -
I see that the ClassLoader exceptions are known, and are "to be ignored".
I left a reference to them, in case they play into our problems anyway.....
"java.lang.IllegalStateException: ClassLoader" - known harmless bug... ?

How do you add Serial Number in Sales AR Invoice

How do we add Serial Numbers in AR Invoice.What is the query. Can anybody guide me with the procedure.

Sanjay,
The sql sample I have given is to demonstrate the use of functions and not the exact SQL to be used for your requirement. BP Contacts is not relevant for you.
Serial numbers by default print on a seperate sheet along with the Invoice if your business process is Sales Order > Invoice (without the delivery step)
If you process involved the delivery step, then the serial number will be printed on a seperate sheet along with the delivery.
The $\[$ is SAP's syntax to dynamically use Form values in your queries.
To understand the usage of this you need to completely understand about formatted seaches.
I was suggesting the usage of functions so that when you add the Invoice, the function would go to the OSRI and SRI1 tables and go in a loop to gather all the Serial number and add them to the User field which can be later printed on the PLD.
