How can I determine the device number from the task ID

I'm using 'Port Config' to initialize my DIO port for a NI-DAQ 6052E. Port Config returns a task id and it would be very useful if I could determine what device number I have based on the task id.

Hello,
Thank you for contacting National Instruments.
It is not possible to determine the device number programmatically from the task id. This would be slightly redundant since you must supply a device number when you Port Config executes. You could simply create a local variable of the Device Number control that is connected to the Port Config.vi if you need to use the device number elsewhere in your VI. Simply right-click on the Device number control and select Create >> Local Variable. Then right click on the local variable and select change to read. This will allow you to read the value of the device number you provided anywhere in your VI.
If you would rather determine the actual device that is being used rather than the device number, yo
u can use the Get DAQ Device Info.vi. I have attached a simple example program that demonstrates how to use the VI.

How can I determine the number and sizes of redologs?

Dear all,
How can I determine the number and sizes of redologs are sufficient to allow redo log switching while hot backup is in progress?
Please advice,
Amy

Two questions here - what the OP put as the subject title and what was asked in the thread, which are different questions.
I would interpret the question in the thread to mean "how to avoid hanging due to archiving waiting for a redo log group to become available." Alert log, wait events, and user complaints would be the source of information here.

How Can I Determine the Size of the 'My Documents' Folder for every user on a local machine using VBScript?

Hello,
I am at my wits end into this. Either I am doing it the wrong way or it is not possible.
Let me explain. I need a vb script for the following scenario:
1. The script is to run on multiple Windows 7 machines (32-Bit & 64-Bit alike).
2. These are shared workstation i.e. different users login to these machines from time to time.
3. The objective of this script is to traverse through each User Profile folder and get the size of the 'My Documents' folder within each User Profile folder. This information is to be written to a
.CSV file located at C:\Temp directory on the machine.
4. This script would be pushed to all workstations from SCCM. It would be configured to execute with
System Rights
I tried the script detailed at:
http://blogs.technet.com/b/heyscriptingguy/archive/2005/03/31/how-can-i-determine-the-size-of-the-my-documents-folder.aspx
Const MY_DOCUMENTS = &H5&
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.Namespace(MY_DOCUMENTS)
Set objFolderItem = objFolder.Self
strPath = objFolderItem.Path
Set objFolder = objFSO.GetFolder(strPath)
Wscript.Echo objFolder.Size
The Wscript.Echo objFolder.Size command in the script at the above mentioned link returned the value as
'0' (zero) for the current logged on user. Although the actual size was like 30 MB or so.
I then tried the script at:
http://www.experts-exchange.com/Programming/Languages/Visual_Basic/VB_Script/Q_27869829.html
This script returns the correct value but only for the current logged-on user.
Const blnShowErrors = False
' Set up filesystem object for usage
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objShell = CreateObject("WScript.Shell")
' Display desired folder sizes
Wscript.Echo "MyDocuments : " & FormatSize(FindFiles(objFSO.GetFolder(objShell.SpecialFolders("MyDocuments"))))
' Recursively tally the size of all files under a folder
' Protect against folders or files that are not accessible
Function FindFiles(objFolder)
On Error Resume Next
' List files
For Each objFile In objFolder.Files
On Error Resume Next
If Err.Number <> 0 Then ShowError "FindFiles:01", objFolder.Path
On Error Resume Next
FindFiles = FindFiles + objFile.Size
If Err.Number <> 0 Then ShowError "FindFiles:02", objFile.Path
Next
If Err.Number = 0 Then
' Recursively drill down into subfolder
For Each objSubFolder In objFolder.SubFolders
On Error Resume Next
If Err.Number <> 0 Then ShowError "FindFiles:04", objFolder.Path
FindFiles = FindFiles + FindFiles(objSubFolder)
If Err.Number <> 0 Then ShowError "FindFiles:05", objSubFolder.Path
Next
Else
ShowError "FindFiles:03", objFolder.Path
End If
End Function
' Function to format a number into typical size scales
Function FormatSize(iSize)
aLabel = Array("bytes", "KB", "MB", "GB", "TB")
For i = 0 to 4
If iSize > 1024 Then iSize = iSize / 1024 Else Exit For End If
Next
FormatSize = Round(iSize, 2) & " " & aLabel(i)
End Function
Sub ShowError(strLocation, strMessage)
If blnShowErrors Then
WScript.StdErr.WriteLine "==> ERROR at [" & strLocation & "]"
WScript.StdErr.WriteLine " Number:[" & Err.Number & "], Source:[" & Err.Source & "], Desc:[" & Err.Description & "]"
WScript.StdErr.WriteLine " " & strMessage
Err.Clear
End If
End Sub
The only part pending, is to achieve this for the 'My Documents' folder within each User Profile folder.
Is this possible?
Please help.

Here are a bunch of scripts to get folder size under all circumstances. Take your pick.

Stolen ipad 4. How can i get my serial number from Apple?HELP!!

My Apple iPad 4 was stolen i do not have the box anymore because when i bought it i was living as an aupair in the USA so on my return after that about 2 months ago my iPad got stolen i never wrote the serial number down did email it to my father though but he lost that email. PLEASE HELP! how can i find my serial number from Apple, they surely should have my serail number on my apple ID???

It seems it was never registered to your Apple ID.
Do you have an iTunes backup of the iPad?
Open iTunes.
Open Preferences. (In Mac OS X, choose iTunes > Preferences. In Windows, choose Edit > Preferences.)
Click the Devices tab.
Position the mouse over a backup to display the serial number of the backed-up device. iPhone and cellular iPad models also display the IMEI/MEID and Cellular Data Number:

How can I determine the type of video out connector I need?

Howdy,
I have a white macbook purchased Jun/2008. I want to connect to a TV but don't know what adapter I need. How can I determine the type of video out jack my macbook has?
System Profiler says the model identifier is "MacBook 4,1". Under Graphics/Displays the only thing it says about the "Display Connector" is that no display is connected. Too bad it doesn't tell me what type of connector it is. If I knew the name of the connector I'd probably be home free. But it seems like every macbook model has a different video connector (since the state of the art has advanced over the years) and I haven't been able to keep up with the names.
Now, I have a 6" long adapter that will convert this connector to VGA. And searching the Apple store for VGA adapters, the existence of mine says my connector is might be one of "Mini DisplayPort", "Apple Mini DVI", "Apple DVI", or "Apple Micro-DVI". But then there is also the connector at
http://store.apple.com/us/product/M8639G/A?mco=MTY3ODQ5OTY
and that looks like the one I have. But unlike the other adapters, this one is just called a "VGA Display Adapter". Does the connector have a name? How can I find adapters that have that same connector?
I know I could use the adapter I have, plus a VGA to VGA cable, to hook up to a TV. But the quality of the VGA signal is poor in the digital world. My goal is to hook up to the TV via HDMI. Is this even possible? By which I mean, will my macbook generate the signals necessary to be able to be converted to HDMI?
Thanks for any help,
Zebulon T

Thanks, Ded,
You're right, the cable that I have won't work. I't from my previous, 2004 iBook. This is pretty embarrassing... I looked at the cable but didn't bother to try plugging it in.
Looking at the close-up picture of the Mini-DVI to VGA adapter, that does look like the right connector. So I have Mini-DVI, and the other apter you pointed to can convert this to DVI. I'll take a look to see what makes the most sense, connector wise, downstream from that.
Thanks very much.

How can I dial a phone number from an email message directly

How can I dial a phone number from an email message directly,
But even before the selection i will change or correct the number?
If I copy the number in the notebook, all spaces are filled with % signs.
When I dictate SIRI the number I get the answer: I do not know the number
If I copy the number in the phone selection (above) the number can not be edited afterwards.

You can dial a number appearing in an email by tapping on it.
But if you need to correct the number first you cannot edit a received email.
To edit the number tap on the forward symbol and when the draft comes up you should be able to correct the phone number, copy it and paste into your Phone App. Then delete the forward email without sending it.

How can I determine the liquid level in a bottle (LabView Vision)?

How can I determine the liquid level in a bottle (LabView Vision)? Does anybody have an example code? The task is, that if liqid level is between two predetermined level, the program writes, that it is correct else it writes incorrect. Thank you.

here is a little play with your bad picture:
used only the small field of interest (here a guess) ,
used only the red channel ( takes out most of the light reflection)
grey scale, 3x(blurr, median filter) , played with contrast -gamma - saturation
now you need to add the edge detection and some sort of scale.

How can we modify the Task Priority in BPM workspace???

How can we modify the Task Priority in BPM workspace??? Is it possible?? If so what is the best and easy way to implement this??

Hi Chandra,
First please find the job name in SM37 for FIGL and check the job status to be in "released" status. Select that job and go to job menu and click on change. then it will take you to the job screen where you have "job class". Here you can change the job class to "A" to get to high priority.
If you are unable to edit the job then create a new job with the same variants by clicking STEP button in the Job screen.
Try these steps, let me know if are able to do so.

How can you determine the absolute path to a dynamically created NetStream object?

We are trying to implement video captioning with a freeware component, ccforflash. This requires us to provide an absolute or relative path to our NetStream object. How can we determine this path in Flash CS5 AS3?
From the CCforFlashCS5 documentation:
"2. Object name and path
Type the name and path. This is the instance name of the object with which CCforFlashAS3 will synchronize. It must be spelled correctly, since CCforFlashAS3 will query the object with this name for timing information in order to synchronize the captions. The path must also be included; either relative to the CCforFlashAS3 component (i.e. this.parent) or the absolute path from the main level of the movie (root)."

It would be easier if the NetStream object was created on an easily identifiable place on the timeline. This player has an MVC architecture. The NetStream object is created in a subclass to Model class, which is itself a subclass of the EventDispatcher object. The View class access it via an interface.
As you can guess, it's not that straightforward to determine where the NetStream object is located on the timeline. This is compounded by the fact that the NetStream object does not have a name property.
I've tried methods like these, but they only work for the DisplayObject class:
public static function displayObjectPath( avDisplayObject : DisplayObject ) :String
var lvPath:String = "";
do
if( avDisplayObject.name ) {
// var obj_name:String = (avDisplayObject.name == 'root1') ? 'root' : avDisplayObject.name;
if (avDisplayObject.name != 'root1') {
lvPath = avDisplayObject.name
+ ( lvPath == "" ? "" : "." + lvPath );
} else {
trace("displayObjectPath() NO NAME avDisplayObject="+avDisplayObject);
} while( avDisplayObject = avDisplayObject.parent );
return lvPath;
} // displayObjectPath
private function showChildren(d:DisplayObjectContainer):void {
trace("showChildren()");
if (d.numChildren>0) {
for (var c:Number = 0; c < d.numChildren; c++) {
trace("showChildren c=",c," name=",d.getChildAt(c).name);

How can I unassign the BB PIN from my BBID Account?
Thanks in advance.
Solved!
Go to Solution.

There actually were several steps that should have been conducted before selling it...refer:
Article ID: KB05099 Steps to take before selling or after buying a previously owned BlackBerry smartphone
The on-device WIPE would have taken care of removing the association between that device and your BBID. Then you could simply use that same BBID on a different device, and that person would have no ability to use that same BBID since they would not know the password.
It is possible (a feature!) to have more than one device on a single BBID, but the result is what you are experiencing. So, I believe the only remedy is that the new owner needs to WIPE that device and start over, leaving you with sole control over your BBID.
Good luck!

VBS:How can i determine the last row of an excel-sheet

I want to replace the chn-comments of an datafile. I pick up the chn-names and want to compare them with an excel-file and so get from the excel-file the right chn-comment and store int back in the datafile. my problem is how can i determine where the excelfile-row is on the end to load the loopounter with corr values.
i know one solution via scan on ascii 13 and 9.but bether is to know immediately the length of the column.
answers also in german possible.

Peter,
Are you using DIAdem's Excel Import Wizard? By "Excel file" do you mean a tab- or comma-delimited ASCII file that Excel can read in easily, or do you mean a file with the extension "*.xls"? You certainly could not search through an *.xls file to find CR/LF characters.
If you use the ASCII or Excel Import Wizard to create an *.STP file for the "Excel" file in question, then after the *.STP file is loaded you have access to a whole range of variables, starting with Ascii... or Excel... which completely outline the structure of the ASCII or Excel file, including things like the row in which the channel comments are, etc.
Why don't you send over your Excel file and I'll be able to help you a lot better.
