Controlling NI2568 Switches using VB6 and DAQmx

Can the NI-2568 (and similar) switches be controlled using VB6 and DAQmx?
I got the impression from the "NI-DAQmx C API VIsual Basic 6.0" Help, that by using the "Digital Output API ", it could be done very similarly to opening/closing a discrete , but no samples were included.
I just need to close a few relays and don't know if I have to install the "NI-Switch" software or not.
If it can be done, what would be the channel string to pass to the DAQmxCreateDOChan dll function
(in place of "Dev<x>/Port<y>/Line<z>"). MAX shows my (simulated-don't have the hardware yet) switch device to be "PXI1Slot3" .
Thanks,
Jon

Hi Jon,
You can also use NI-DAQmx Switch functions to control PXI-2568 rather using NI-SWITCH (NI-SWITCH installs ready-made VB examples)
You can use functions such as
DAQmxSwitchSetTopologyAndReset, DAQmxSwitchCloseRelays, DAQmxSwitchOpenRelays to control individual relays in PXI-2568. ANSI C Examples for DAQmx switches can be found at C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Switches. This can be used to write VB 6 code. Refer to using "C Examples to create VB 6.0 Applications" in C:\Program Files\National Instruments\NI-DAQ\Docs\cvb60daqmx.chm for help on converting C examples to VB 6.0.

Defining sort criteria using vb6 and CR XI

using vb6 and cr XI and I am trying to provide the user with the capability of defining sort options using options defined on a VB6 form. The sample code I've found as described below doesn't seem to allow me to change the sort criteria by field name
'General Declarations
Dim CRXDatabaseField As CRAXDRT.DatabaseFieldDefinition
Private Sub Form_Load()
Set CRXDatabaseField = CRXReport.Database.Tables.Item(1).Fields.Item(8)
CRXReport.RecordSortFields.Item(1).Field = CRXDatabaseField
I would like the user to select an option to sort by say Client and then provide this information to the report like I could with CR 7 as follows
crReport.SortFields(0) = "+{Horse.Location}"
Thanks for any help

Unable to Meke EXE using VB6 and CW

I know that I will be a little bit long, but that's the only way to be precise.
So please, maybe someone out there can help me, since th NI Knowledge Base
didn't ...
We use ComponentWorks 2.0.1 and we also got 3.0.1 update.
My computer runs Windows98SE (German version) on an INTEL Pentium III - 600
MHz.
Using Visual Basic 6.0 (SP4) and trying to "Make EXE" the compiler stops
when displaying "Writing EXE" at about 80% gauge. The error message will
always be (I try to translate, since I use a German OS):
"This application was closed due to an critical error". And: "VB6 caused
an critical error 10H in module CW3DGRPH.OCX at 016f:07c5a14e. ..."
If I click "Close" the whole VB6 environment will close. If I click "debug"
C++ comes up and says: "Unhandled exception in VB6.EXE (CW3DGRPH.OCX): 0xC0000090:
Float Invalid Operation". In the disassembly line stands: "07C5A14E fld
qword ptr [esi+200h]"
What did I try to resolve the problem?
1. I installed a "clean" Windows 98 (First edition!), installed my components
and VB6. The error did NOT occurre! After installing a newer dated application
(Outlook Express) the error came. So I guess it will deal with some overwritten
dll or so.
2. I installed Win98 SE and the error always occurred.
For Your information: I named my Windows directory "C:\WIN" and teh System
directory is "C:\WIN\SYSTEM".
3. I reinstalled CW2.0.1 and tried using CW3.0.1. No change. I still couldn't
make the exe file.
The OCX files seem to be registered properly.
(BTW: Any other application not using Component Works can be made to EXE
files.)
4. In my office others are working on this project too. They use Windows
95, Win2000 and Win NT4 WITHOUT any trouble. None is using Windows 98SE.
I am almost changing to Win 2000, but first I don't think it is a secure
way to handle the problem. Who knows, if it appears some day again when any
specific dll or so had been changed in the system folder? And second, I might
need a hardware based OS some day in near future and wish to have Win98 SE
again on my disk.
In all above cases the error message was the same.
Thank You in advance.

To make ur Project an exe file u should have the full version of the cw works installed. As expected of exe files it should run on any machine. so the best way out ( the way i used in my project ) is to go to start -> programs -> measurement studio tools -> package and deployment wizard,click on it. It will ask u to select the project. chose it from ur dir and clik on the PROJECT button.
the wizard will guide u through the rest of the set up. and it will create u a set up file which u can install like any windows application.
This method has always worked for me.
all the best

NAC : CAM control over switch using SNMP

Hi
I have CAM , CAS in Central, OOB,Virtual,Layer2 lab
I can see on CAM the access switch ports status which means that SNMP works but when a user is logged on the access switch , the user vlan is not inforced to be changed to Auth vlan
and he remains in the trusted vlan which is already configured on the acces switch
I can change in configuration on the switch through CAM but the CAM itself cant change Vlan
thanks to advise me what part i am missing
thanks

in the CAM, when you see the access switch ports status, click on the magnifying glass icon next to a port which is up and see if it's detecting the MAC address of the device which is connected to that port. If it is not it means that SNMP mac-notification is not configured properly. If CAM doesn't detect the MAC address of the device, it wont change the switchport vlan...

Control which apps use en0 and en1 (airport & ethernet)?

Hi,
I've got access to both my shool's wireless network and my own cable modem account. Is there any way to direct particular kinds of traffic to a particular network interface -- for instance, if I want to play games over one connection and use the other for surfing, email, etc?
Supposedly the order of the interfaces in the Network Preferences list dictates which has priority, but is there a way to set up exceptions for particular applications?
thanks a lot,
Lucas

...that helps, thanks. One thing - from what I can see so far route lets you select by the destination address, but not by the application making the request. (Maybe it does and I missed it.) I keep thinking there's gotta be a way to aim an app at a particular network interface...
cheers

Simultaneously Connecting Multiple Tables of the same Database to Textboxes of the same Form using a single ADO Control Code using VB6 Enterprise Edition and MS Access 2007

Iv 10 Tables consisting of atleast 10 fields each in a single Database. Bt, Im only able to connect 1 table at a time to a form using an ADO Control. Im able to add data from table 'student' to text-boxes in my form. Bt, hw can I add data from field(0) of
Table 'Student' to Textbox1 and data from field(0) of Table 'Marks' to Textbox2 using VB6??
This is the current sample coding iv got to connect a single table to a form:
Global con As New ADODB.Connection
Global rs As New ADODB.Recordset
Public Function Connect()
If con.State = 1 Then con.Close
con.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + App.Path + "\bca.mdb;Persist Security Info=False"
End Function
Private Sub Add_Click()
If rs.State = 1 Then rs.Close
rs.Open "select * from student", con, adOpenDynamic, adLockOptimistic
rs.AddNew
rs.Fields(0) = (Text1.Text)
rs.Fields(1) = (Text2.Text)
rs.Fields(2) = (Text13.Text)
rs.Fields(3) = (Text4.Text)
rs.Fields(4) = (Text5.Text)
rs.Fields(5) = (Text6.Text)
rs.Fields(6) = (Text7.Text)
rs.Fields(7) = (Text8.Text)
rs.Fields(8) = (Text9.Text)
rs.Fields(9) = (Text10.Text)
rs.Fields(10) = (Text11.Text)
rs.Update
MsgBox " Record Added"
End Sub
What can I do to add fields from 2 different tables to different text boxes within the same form using a single ado control using vb6 and MS Access 2007??

How to control a solenoid via PXI-2520 and DaqMx Switch

I am a LabView novice with Core 1 and Core 2 training so I am familiar with the fundamentals of LV process flow however, this is the first application I am attempting to develop that is not a simulated training VI. That said, I am having trouble ironing out the necessary logic to control a 10 solenoid 2 position valve manifold. I have developed a VI that will contact and disconnect a particular relay in the style of the "Switch Controlling Individual Relay.VI" on my PXI-2520 module but these are single instance events. Ie. i set the device, name the relay, and tell the VI which action (make or break) and run the VI. What I am trying to develop is a continuously running VI where any one or multiple solenoids can be energized/de-energized using simple boolean control whereby each relay is represented by a switch on the front panel.
It is clear that a while loop is necessary and a series of case structures or State Machine architecture is necessary but all my attempts have been fruitless. the common failure mode tends to be when following iterations of the while loop tell a switch that is already open to reopen or vise versa thereby causing an error. My thought here ist that some feedback from a former iteration is necessary so that only "unequal" boolean values for the former iteration calls a case to connect/disconnect. What are your thoughts?
Eventually this VI will also need to control these solenoids automatically (i think DaqMx Create scan list with software triggers will suffice) but each action willl need to be timed. For now though it is most critical that I have the capability of operating the solenoids manually and dynamically.
Thankyou,
DK01

Welcome to the forums!
If you can, please post a snippet of code from what you've attempted so far. We can take a look at it and make some recommendations.
One of the lessons in Core 1 also talked about the use of the event structure. It may be a good use case for an event driven state machine that can modify the states of specific switches.

How to remap keyboard - Looking to switch the "fn" and "control" buttons?

Hi I was looking for a way to switch the function and control on the bottom left side of the keyboard on my macbook pro laptop. I am used to the control button being the button that is furthest to the left and its just really throwing me off having the fn key all the way to the left. If anyone knows how to remap these keys, I would really appreciate the help.
Thank you.

Firefox 4.0 has a combined Reload and Stop and Go button that appears at the right end of the location bar.
To restore the Firefox 3 appearance you can use these steps:
* Open the "View > Toolbars > Customize" window to move the Stop and Reload button out of the location bar.
* Move the Reload and Stop buttons to their previous position at the left side of the location bar.
* Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.
* Set the order to "Stop - Reload" or separate them otherwise to get two distinct buttons.

Switch the function and control keys

Sounds like a stupid request but my life would be much simpler if my Lenova T540p keyboard had the function and control keys switched. I use the control key ALOT and having it to the far left hand lower corner would be awesome.
Thank you.

Hey there Redrabbit,
Try your BIOS. For me (Thinkpad T540p), it's in Config>Keyboard/Mouse>Switch FN and CTRL keys.

Ni-daqmx using vb6

Hi
iam trying to connect ni-daqmx to vb6 and here is my code.
Sub temp1()
Dim mytask As Long
Dim Data(1000) As Double
DAQmxErrChk DAQmxLoadTask("temp1", mytask)
DAQmxErrChk DAQmxReadAnalogF64(mytask, 1000, 10, DAQmx_Val_GroupByChannel, Data(0), 1000, 1000, ByVal &O0)
Text14.Text = Data(1) ' for displaying data in textbox
Text14.Text = Format(Text14.Text, "#00.00") ' making 2decimal digit
DAQmxErrChk DAQmxStopTask(mytask)
DAQmxErrChk DAQmxClearTask(mytask)
Exit Sub
errorhandler:
DAQmxStopTask mytask
DAQmxClearTask mytask
MsgBox Err.Description
End Sub
Private Sub cmd_acquire_Click()
Timer1.Enabled = True
Timer1.Interval = 60000 ' setting 1minute
End Sub
Private Sub Form_Load()
Timer1.Enabled = fasle
End Sub
Private Sub Timer1_Timer()
temp1
End Sub
like wise i have 8-10 task whih diplays the temperature value in text14 to text22
using timer iam calling this function for every 1 minute ,
iam getting data but as time progresses the data capture is getting delayed means initialy it will execute at 1minute
after say 1or two hours the capturing is getting delayed by 30-40 sec.
iam using scxi chasi with temperature module. using task iam calling in to my vb application.
iam unable ti figure out the route problem for time delay.
Regards
Raj

Hello Raj,
Yes, so since the program runs continuously, and the Windows OS is not deterministic unlike Real-Time OS which is deterministic, the processor usage builds up and it slows down on continuous run of the LabVIEW application, so the time taken increases down the line. This kind of behaviour is expected and can not be avoided on the PC.

Strongly recommended: ios7 control center switches to user-defined, we can add the cellular and 3G switch.

How do I use the time capsule to share itunes music between multiple apple devices? Also, is it possible to control the music on one device using another, and how do you set this up?

unless i'm missing something, i think you got mixed up, this is easy google for walk throughs
i'm assuming this is the new 3tb tc AC or 'tower' shape, if so, its wifi will run circles around your at&t device
unplug the at&t box for a minute and plug it back in
factory reset your tc - unplug it, hold down reset and keep holding while you plug it back in - only release reset when amber light flashes in 10-20s
connect the tc to your at&t box via eth in the wan port, wait 1 minute, open airport utility look in 'other wifi devices' to setup the tc
create a new wifi network (give it a different name than your at&t one) and put the tc in bridge mode (it may do this automatically for you, but you should double check) under the 'network' tab
login to your at&t router and disable wifi on it
add new clients to the new wifi network, and point your Macs to the time machine for backups

How do i drag indicator control type on WPF instead of using Drag and Drop points

In my WPF application, i have a window which is docked with the screen. i want to automate to expand the window using an Indicator control type, by sliding it. As of now i use StartDrag and StopDrag using specific points, which is not correct when it runs
in many other screens.
Could you please let me know, is there way to slide the control (to set window display size to viewable) without using drag and drop action using points.

Hi Pavithra,
>> As of now i use StartDrag and StopDrag using specific points, which is not correct when it runs in many other screens.
To really understanding this issue, could you share us what you mean by ”which is not correct”? It would be much helpful if you could share us a screen shoot about your UI and your issue.
>> Could you please let me know, is there way to slide the control (to set window display size to viewable) without using drag and drop action using points
Do you mean that the control of the WPF is invisible and you want to set the window display size to make it visible? If so, I think you could use the Mouse.MoveScrollWheel Method to change the windows view until the control is visible. The link below might
be useful to you:
# CodedUI cann't find the controls outside the screen view, Mouse.MoveScrollWheel doesn't work too

If I misunderstood you, please feel free to let me know.
