I have done a similar thing, only I stamped the time and five readings. see the code at http://forums.lavausergroup.org/index.php?showtopic=1060&hl=

The basic idea I used was to count miliseconds and insert that into the array of other readings before writing to a file.

Good luck

I wonder whether the attachment you uploaded is a working VI? Coz I am a student. When I want to test my VI, I need to access to the lab to verify with the DAQ card I am using. Thanks for the help any way, what I want to do is very much similar to what you did, except for the motor part. :thumbup:

I am building an application which requires data from DAQ card. The values are successfully read from the DAQ card, but I need to capture the time when every single value is captured. I am midifying my aaplication from the one channel oscilloscope Vi from the example library. The current method i use is by dividing thye difference of time from each loop and the next loop with the sampling rate and incrementally add the time to the initial time. I am attaching the VI for convenienceof debuging application. Hope some one can offer a helping hand.

The standard and full version require the application builder to be purchased and installed in addition to LabVIEW. The professional version already includes it.

To see if you have it... Go to the 'Tools' menu, if you have an entry there that starts with "Build Application..." then you have it.

Thanks for the information. I have the application builder in my version of labview When we use the tool to build the application, do we need to open the file to be built or we can just specify the source file from any VI that we open the tool from?

Thanks for the recommendations Form all the alternatives, the SQL toolkit seems to be the easier to modify to my need as I can customize the SQL statements according my my needs. Highly recommended for all other newbies in developing database applications using labview.

maybe you should have mentioned that you can build an installer package of the vi which allready contains the LabVIEW Runtime Environment (LV Runtime Environment is Freeware ...) with the Application Builder.

If you don't want to use an installer but only the .exe you have to ensure that the LV RTE is allready installed on the target machine. the application builder reminds you of that after finishing the compilation ...

best regards,

Yes, i would be delighted to build an installer package of the vi. I am not sure whether the application builder is available in the labview version i installed. Is there any way to check it out?

Hi,

I wonder if any one has the experience of transforming a VI into an executable file so that computers that has no labview installed can still use the User Interface I created with the DAQ card installed.

Hi, I am new to labview and I was struggling in connecting labview to my microsoft access database for a few months until i found this website recommended by Michael Ashe:

This module is rather simple in execution and the SQL statements can also be customized according to need. The most impotant thing is you understand the concept of the execution. By the way, remember to register you database at the ODBC in order to make modification to the database. Good luck!

maximus,

My project is a small scale project. I think purchasing the database toolkit will be too costive. That's why i am considering using activeX which i am not familiar with.

rkanders,

FYI, the toolkit you recommended is developed for LV7. It cannot be used in my version (6.0) of LV. However, I've tried to open it in the LV7 Express Eveluation software that will expire after 30 days of use and thus I try to reconstruct those VIs in LV 6.0. There is this element that I tried to add into the property node, as attched, I don't know how to get it done. Could you give me a hand in this? Thanks.

Hi, I hav just started to learn ActiveX to write data into my database developed using MS Access. I need to update my database everytime I execute my VI. FYI, I am using LabVIEW 6.0. I have found an example of how to read from a database but have no idea how to choose the method and property. Have anybody have any VI or any good material to read on about ActiveX property other than the brief intro doc available in NI website? Your help will be very much appreciated.
