  1. I thought I read or heard that there was a way to add a prefix to all VI's automatically when creating a source distribution from the project Explorer, but I don't see it. Is this possible?
  2. Often when I am using a multi column listbox I put a row of pull down menus across the bottom of the listbox, sized to the same width of the columns. Usually I dynamically stuff these pulldowns from a database or something, the user selects the row of intrest in the listbox, makes whatever selections he wants in the pulldowns, and the hits the update button, which then stuffs the pulldown values into the row of the listbox that is selected, each pulldown value into the column it is beneath. Sounds a little confusing, if your intrested I can send you an example.
  3. Assuming that you want this information to prevent piracy, another option is a USB dongle. This gives the customer the flexibility to install the application on other machines, but only run it on one machine at a time (The machine that has the dongle on it) I get my dongles at MAI Digital Security, they are only 20 dollars, and come with LabView VI
  4. Since LabView8 we are trying to establish Subversion (TortoiseSVN under WinXP) as versioning tool. We want to keep under control all vi
  5. I have an interactive program with a graphical user interface in which data is filtered using a filter. There is a button on the user interface that would allow user to modify the filter properties. Pressing this button would pop up a configuration window, where the user can configure the filter properties. I use the same filter as part of my non-interactive programs. To allow fast configuration I have created an express vi from my filter. The configuration happens easily using the express vi configuration utility which I have written. The problem is that I need to code the same or similar us
  6. Mr. Neville, Thnks for the complement but i ve download it and try to run it butttttttttttttttt any of the vis are not excecutable bcoz of one or other reason, so can u help me other ways, that i can do it. thanks for the complement again. Thanks, Nishant
  7. Thanks Mr. Massey, Now I want 2 know from where u ve get the Excel Tollkit, hav u purchased it or download it from anwhere? i don have any kind of excel toolkit, so i am bit confused, wat to do???????? Thanks, Nishant
  8. Dear All, While writing the data into the xls file through .lvm method I want the Heading for each channel to be include on each of the column, but i dont know how to do this?:headbang: is this possible in the LabVIEW from any of the file writing method? if yes how can i do that? please help me......... :question: Thanks, Nishant Desai
  9. Hii Cookie, While saving the data into the excel file you arer getting the wrong date format mean you are writng it from the graph, bcoz the problem of 1904 is also in the real time graphs when we are displaying the data into it, of that problem what you can do is I ve written all the proc below and i also ve attached the sample vi. By default, waveform charts and graphs display the absolute time at time 0 as 7:00:00 PM, 12/31/1903 on a Windows based system. Property nodes can be used to get the correct absolute time to display on the x-axis of the waveform chart. First, right click the c
  10. Dear Friends, As I am reading the data from Excel file, i want to plot it in the graph as historical data and the thing i want that the data is shown as they are written in the graph with the time stamp, i am giving the time stamp as the comment when writing throgh the .lvm file procedure but just selecting the .xls file instead of .lvm file, and i dont think that the file type makes the difference, is it??????? if it please also let me know. Here with this I am attaching a file in which i ve shown that how i am writing the file......thanks.Download File:post-3625-1133929661.zip
  11. I think You stuck up while overwriting file options, generally, the overwrite mean that, it wil overwrite the current existing file, but it wont do so, it will create a new file in the overwrite mode and checks if the name of new file is existing???? if yes it ll overwrite that file name else if Append mean while it wont create the new file but Append the data into existing file.
  12. :arrow: I have stuck up with writing the files in the LabVIEW, i want to do the Fifo(First in First Out) while writing One continuos file to .lvm type, I cant do this with options of the LabVIEW, can anyone suggest me how can I do that? please give me the solution. :headbang:
  13. For LabVIEW to read an array from the FPGA VI front panel it needs to read every array element individually across the 32-bit PCI bus. In addition it needs to perform a few cycles of overhead operations before being able to retrieve the data so it will take a bit longer to read an array than reading the same number of element individually from a synchronous display indicator. In LabVIEW 8 you should use DMA to transfer data from the FPGA to the host. The Flip-Flop setting uses FPGA real estate to store the data in the FIFO; block memory uses the additional user memory on the FPGA. In most a

  15. I wrote the original version a few years back before I truly understood the problems of the sequence structure. Now I do. The modified version you see in LV8.0 was just someone trying to clean up the readability without risking breaking something. I don't think any real functionality changes were made. Oh, and, no, I'm not certified. :-) -- Stephen Mercer -= LV R&D =-
  16. Hi Everybody... I use LabView for many applications. And whatever our clients need. I may attempt writing a video game for fun... JLV
  17. Are you still looking for the manuals? I may have a soft copy somewhere...
  18. You can use your parallel port as a free little DIO card! You get eight bits of output and five bits of input. If you can determine which address your port is using, it is a simple matter to use the "In Port.vi" and "Out Port.vi" (except on WinNT) to read from and write to your parallel port. WARNING!!! Be careful not to short anything out, as this port is built in to your computer, and inadvertently touching the wrong pins together for just a millisecond can destroy your port! These pins, as output, can only drive a tiny amount of current, so you would need additional circuitry to drive rela
  19. There is a bug in LV7.0. If you make a control Blinking (set its Blinking property to TRUE), and then place the VI in a subpanel control, the blinking will not be seen except sporadically. I built one VI (Master.vi), which if you open and run, the blinking works fine. Then someone pointed out that it was silly to put the Insert VI method call inside the while loop. So I rewrote it (Master2.vi) and the blinking stopped working. It seems (my best guess) the subpanel only updates its draw state during a value change event or when a drawable property is changed. Since with blinking, no value is
  20. This was already submitted as a follow-up from NI tech support, I'm just sharing it with LAVA. LV 7 allows some menus to be abridged, i.e. unused items temporarily go away as in MS Office applications. NI tech support confirms that is not yet available in apps built with LV 7, so I submitted that feature request. It'd be great to have our applications abridge their own menus. Best, Mark
