    You should have a look at the examples shipped with LabVIEW: Hardware IO\DAQmx\Synchronization\Multi-Function\Multi-Function-Synch AI-AO.vi. Express VIs are not suitable for such tasks. You try to acquire for 90 seconds of data in one shot, this will (standard) not work since you have a timeout of 10 seconds. Ton

    QUOTE (crelf @ Jul 20 2008, 04:44 PM) Another great resource to take advantage of at NIWeek is the NI Systems Engineering group. SEs are available to meet with you and discuss your individual applications in person and provide recommendations for the design and architecture of the application and answer other development related questions. Offline SEs can work on additional benchmarking of using NI products in specific applications or can work with you to analyse and understand specific risk items in your application through prototyping of application components. Systems Engineering is an extension of the NI field sales and business development team, providing more advanced technical resources to customers during the application design and architecture phase. We work closely with the R&D and product management groups to get your questions answered and guide the direction of product development to improve the customer's application development experience. Systems Engineering subgroups specialize in the following application areas and associated products: Automated Test (including Vision) Embedded and Industrial Control (including Motion Control, Sound & Vibration acquisition and analysis) Control Design and Simulation (HIL, RCP, aerospace and automotive control) RF and Communications Please contact your local FSE/DSM to arrange a meeting with a SE during NIWeek. If you have any difficulty getting this setup, you can also contact me directly at my NI e-mail address and I can help you. Christian Loew

[Pushing my knowledge = False] The Trace Execution Toolkit is something I have only used in the RT environments but is supposed to run under Windows now. It works by putting hocks into all of the code before you run it and will produced detailed reports of everything that called when for how long and also gives you an idea if anything goes idle waitng for memory management. That toolkit may be helpful. Ben

    QUOTE (Norm Kirchner @ Jul 18 2008, 05:34 PM) Sure is! If you are looking for gloabl solution that finds which of all of the VI's in memory are running, (note: there maybe more than one running) it seems you would have to interact with the OS's scheduler to do that since LV utilizing the OS to schedule VIs and for that matter the multiple possible threads within each VI. The only other thing that I feel is worth mentioning is the "skip if busy" option availabe for VI's marked as sub-routine. When a subroutine VI is dropped on a diagram, it exposes an option called "skip if busy". This option is the one and only exception to the data flow paradigm in that when that option is selected AND the VI is alredy executing, the sub-VI call will be skipped. If there any return values expected from the VI that was skipped, LV will use the "default" for the data type (Note the default as defined by the sub-VI will NOT be returned since LV would have to access that VI to know that and since its being skipped LV does not know that). So... If the VI in question is structed like an AE you could call it using a "check method" that returns a true boolean. If you try the "check" and it returns false, the VI was skipped because it was busy. Those are the only thoughts I can offer. Anyone else have thoughts on this matter? Ben

Enabling the string control makes the right-click working (it already worked on the picture control). To disable selecting of the text (which is most likely why disabled it) you should filter for mouse-down? events on the array. To disable the changing of the mouse you should look for mouse enter and leave events and alter the mouse as desired. Ton

    Shane's Nugget on on using VISA to access USB devices (found on the dark-side)has branched into a possible universal USB driver architecture that may harness LVOOP to allow for adding other devices in the future. If you are interested in LVOOP and have any advise you can offer, it would be greatly appreaciated (by me). Even if you can't offer any assistance, you may find that thread interesting (if for no other reason just to laugh at us trying). Ben

    QUOTE (Götz Becker @ Jul 16 2008, 03:20 AM) The inplace structures are new enough that I can't speak specifically about them but as I undersand this code guide-line intent... When LV has decide how it has to pass data to a sub-VI it first tries to do it as effciently as possible. Since copying data (particular large arrays) is time consuming, it tries to avoid doing so. It can avoid copying the data if the data is not modified in the sub-VI. But how does it know if the sub-VI modifies the data? The sub-VI itself can let a caller know it is not going to mod the data. THis condition is possible if the controls indicator that are on the icon connector are located on the root of the block diagram. I look at it this way. The caller can look into the sub-VI only as far as the root of the diagram. If it can see the data will not be modified, it only passes a ref to the buffer holding the data in the calling VI. If you run your two VI examples through the same benchmark test I post in the thread on the NI forum, you MAY be able to see a slight differnce in the two methods. Ben
