HI,

I'm trying to read a text file and based on some condition I need to delete the file. The problem is that sometimes I received the error 5 "File already open" and I don't know why, I close the file after so I have no idea why it could be still open.

Thanks for your help.

It appears that you're trying to directly call a DLL that contains an Automation, OLE, or ActiveX component (no idea what the difference is between these, they may all be names for the same Microsoft technology). Take a look at the ActiveX palette. Drop "Automation Open" on your block diagram, create a constant for the Automation Refnum input, right click on the constant and choose Select ActiveX Class -> Browse, then in the dialog box that appears, browse to your DLL. See if you can then use the ActiveX invoke and property nodes to access your functions.

Thank you very much, you´re right, I now can access the functions via ActiveX.

Thank you again.

Hi,

I´m trying to call the function GetUnitInfo from a Dll in Labview 8.2. The problem is that when I try to configure the Call Library function, I can not see this function, and Its suppose that this Dll only contains 2 functions (GetUnitInfo and SaveResults).

Instead of the 2 functions mentioned, I see the following:

DllCanUnloadNow

DllGetClassObject

DllRgistrServer

DllUnregisterServer

I don´t have access to the Dll code, so any ideas what could be wrong??

Thank you in advance.

Hi,

Hope this help.

What is the order you installed your software?

You should install LV first, then the Vision stuff. If you are using Vision 7.1.1, then you need a number of components from different cd's installed. As far as I remember,

IMAQ Vision, IMAQ for 1394 etc. etc.. its been a while since I used 7.1.1 but the newer versions of Vision have everything integrated into a couple of CD's instead of a million separate components.

Also, have you activated your Vision package? Maybe it is not allowing you to generate VI's because of that.

Another thing: check that LV8 is indeed compatible with Vision 7.1.1 (I think it should be, but check on the NI website or the LV 8 release notes).

Neville.

Thanks for your response.

I first installed LV, then Vision, anyway I've delete all vision stuff and reinstalled.

Yes, the vision is activated.

I'll check the compatibility, thank you.

Hi,

I saw some topics related to this problem , but none helped me.

I'm using vision assistant (7.1.1) and want to create a Vi from my script, but I always received an error message "Lavbiew and Imaq vision not found". I have Labview 8.2 in windows vista. can anyone help me solve this problem, in fact I reinstall the vision development but I still receive the error.

Thank you in advance for your help.

The best way that I found to check communication of xbox-PC and the IP address of the Xbox once connected was to use the "IPconfig" and "Netstat" commands from the sys exec, then I read the files and search for the good connection status and IP address. Not very elegant but it works well.

Thank you for your help.

Thanks you for your help, I'll check that.

Unfortunately, I can't obtain any information about this.

Basically I only need to know the IP address of the Xbox, so I only need to know how to read the IP address once the xbox get connected to the computer, I've tried this Vi but I can't read anything.

I'll really appreciate any help.

Thanks you for your help, I'll check that.

Thank you in advanced.

Great, thank you for your help.

Hi to all.

How can I change the default value of a control while the program is running, I mean , I have a 4 as a default value of a numeric control, but I want that the user can change that value and save it, so the next time the program run, the control use the last saved value.

I just need to do that for that single control, so I don't like to use a init file, is there any property that can do that?

Thank you in advance.

Hi to all.

I'm almost new to LV, and I wonder if you can change the properties (ex. visible) for the labels or decorations in Front panel.

I know how to use the propertie nodes for the indicators or switches, but I can find the same for labels.

Tnxs in advance.
