NI Week 2017 is about 10 weeks away - seems odd saying that in March. Any news on the LAVA BBQ?
-
Yes, in fact I haved looked through those - it was the first thing I did. The heaps of results on Google resulted in several Blocked sites(corp Internet filters), others that had advertising for shareware, a couple that directed me to NI Forums that said that EXIF wasn't supported in LabVIEW, suggesting finding a 3rd party API to access the data would be the answer. Since, time is money in our business, I thought I'd pose the question in LAVA to help the cause as well. I guess I'll just go back to the heaps of Google results - I'm sure that I just overlooked the project saving link...Thanks!

Has anyone been able to read/write EXIF data via LabVIEW or should I look at using some other API?

Running System Exec vi as Administrator in Win7
BobbyCee replied to BobbyCee's topic in Calling External Code
Thanks for the code snipet, Shaun. I did try out your method and had a User Account Control popup appear. I did some futher MSDN reading and it looks like via impersonation I may be able to run my administrator account elevated so as to not need to acknowledge the UAC popup. This system will be used without a monitor and will not have user interaction. I need to keep standard permissions on the box because the system will be on a network and I want to limit people running scripts that could affect system operation. I will post this code as soon as I get it tested successfully. Thanks again for showing me another way to access Process Start Info processes! -
Thanks Tim. I do use OPC quite often, but mainly for monitoring tags. As you said, machine control is possible, but it's not a can o' worms that I want to open. I noticed that NI does sell a Profibus card, I just haven't ever heard of anyone using it. My goal would be to connect to the Siemens Profibus Master and use LabVIEW to communicate with the Siemens symbols - I was also curious to find out if using LabVIEW profibus drivers was a cumbersome activity or not.
-
I am interested in finding out how many of my fellow LAVA lovers have had success interfacing LabVIEW with PCS 7 and what method was used to communicate - i.e. Profibus, OPC, etc

Running System Exec vi as Administrator in Win7
BobbyCee replied to BobbyCee's topic in Calling External Code
You are correct, higher administrative privileges are needed to control services. I have found that the .NET architecture is more flexible than simply using System_Exec.vi with string commands and therefore I will be pursuing the .NET method to handle querying, starting, and stopping my local services. However, I will have to talk with the system owner regarding the removing the User Access Control level that prevents interaction at the service level. I am fortunate to have a number of in-house resources to offer expert advice on .NET coding and will share my findings with the LAVA community. -
Running System Exec vi as Administrator in Win7
BobbyCee replied to BobbyCee's topic in Calling External Code
OK, Wiki sounds like a good idea. I am also experimenting with a .NET assembly to perform the same task as the System_Exec.vi. I think I may be able to write .NET code that will allow Win7 application control to maintain higher User Level Security and still Start and Stop my desired local service. -
Running System Exec vi as Administrator in Win7
BobbyCee replied to BobbyCee's topic in Calling External Code
Looks like I found the solution to my problem. After changing the User Account Control settings to 'Never Notify' and rebooting, I was able to run System_Exec.vi with my Start / Stop service commands successfully. -
Has anyone been able to run the 'System Exec.vi' as Administrator using Win7? I have a service that I need to start and stop and can do so with the following cmd line: cs start mxchange OR cs stop mxchange The catch is, in Win7 I need to be running CMD as Adminstrator Any suggestions?

I am trying to programmatically scroll the entire Front Panel vertically, after programmatically resizing a window. Any suggestions on how to access the vertical scroll position would be great!

Does anyone know of a LabVIEW user group in Mid-Michigan? If not, would anyone like to start one? I live in Midland and know of several developers living in the Mid-Michigan area. It would be great to have a centralized group. So, if there are any wireworkers interested in getting together from the Mid-Michigan area, let me know!

Suggestions for Multiple UUT Controller
BobbyCee replied to lvb's topic in Application Design & Architecture
Have you considered using GOOP in your design? Treating the "stations" as objects will afford tremendous flexiblity in your design. Also, what type of daq hardware are you considering/using for your application? -
QUOTE(crelf @ Dec 19 2006, 07:03 PM) Using the "update window" User32 function call following your "float on / float off" mode change will do the trick. Glad you are my boss :thumbup:

Hello All, My name is Robert Cummer and I just recently joined the fabulous VI Engineering family, located in lovely Farmington Hills, MI. I have been using Labview since the mid '90s. I have been a test engineer for most of my 13yrs and an "dedicated" software integrator for the past 2. I look forward to sharing experiences with you all - whatever that means!?! Later Bob
