Ok, i find that After converting Vi's to 8.6, Labview autodisconnect rename column and Delete column to prevent recursion. There is a SQLite_Query.VI that is recursive and cause problem with versions 8.6. SQLlite_query3.vi cause the problem.

I Didn't make an example i only created a new blank vi and place a Table.vi inside. Could it be a converting from LV9 to LV 8.5 problem? To make this i had to convert to 8.6 first and then with LV 8.6 to 8.5...maybe something get lost inthis step. I created a New project but the OS variable was not "Unix" but "Linux" and the bitness variable did not exists. Now i'm trying reconverting Vis from LV9 to LV8.5 and using a project, i'll let you know if i find something new

Hi! i'm porting this toolkit in Ubuntu Linux with version 8.5 of Labview. Some polimorphic vi needs to be modifyied to work correctly such as SQLLite_Delete column.vi and SQLLite_Rename column.vi it said that "you cannot use "SQLLite_Rename column.vi" recursively, so i deleted them After that you place a conditional disabled structure for Unix but to make it work i had to change that condition from OS==Unix to TARGET_Type==Unix. I try changing it in OS==Linux as i see in the conditional Disable Symbols, but it didn't work the first time it said that OS was undefined. now i start labview again and it seems to work...what is better? OS or Target_Type? Instead, TARGET_BITNESS is an unexisting variable.

Thank you so much, i'll take a lookat it!

Two years and now i'm here again with the same problem. Unfortunately the author of the wrapper is missing. Does anybody think to be able to develop a wrapper for sqlite3 for Linx systems? Unfortunately i'm only a LabVIEW programmer and i don't know C code so i can not make it by myself, but i think that this could be an important step to improve the labview for Linux usability. What do you think about it?

Hi, I'm a Labview user that is trying to convert some program from windows to Linux. At the moment i'm converting a software that use the "SQLite WRAPPER for LabVIEW" but i found some problem with it. I replaced the lvsqlite.dll with the sqlite3.so but unfortunatelly i think that the prototype of the functions are different. Does anybody want to help me in this project? I think that SQLite3 is a very usefull database system and very simple to use. A conversion of this toolkit can improve the usability of LabVIEW for Linux in spite of the NI politics At the moment i converted the Open function and it seems to work. The exec function is giving me some problems....I'm not a C expert so maybe there is something wrong with the prototype. Take a look at the screenshot, there are my laview prototype and the C structure of the function. Hope that someone would like to help me. This is only an exercise for me, not a commercial product, so i hope that someone is interested on it. ...ma ciao! Geppo!

yes but.... in LbVIEW 7.1 there is no "show folding" options...... :headbang: :headbang:

This bug worries me a lot...how can i go on if i can not rely on labview??? So i made some test. The error occur at the indexing in the while loop. If we carry the 2d array into the while loop and extract each element using the index of the cycle no more error occurres. So....there must be an explanation to this thing... I don't like auto indexing in the while loop...i use them only when are useful even to determine the number of cycles of the for loops. Can it be relate to this bug? Three Cycles..same operations... only while loop is wrong... It's not possible such a bug! and.....if the problem is the "+1" module combined with the while loop? If we substitute the "+1" with a sum with an array of 1 the problem don't occur. Download File:post-1899-1157618194.vi

...ma ciao! I'm developing an application that open in an ActiveX container (WebBrowser) an image that is hosted on the web. To show this image in an image indicator i need to save it on my hard disk (right??). To do that, i use the ActiveX method ExecWB whit the cmdID "OLECMDID_SAVEAS". This command has different option, i need it not to show the dialog and save the image directly in a specified path. So i set the cmdexecopt to "OLECMDEXECOPT_DONTPROMPTUSER" and MAYBE i have to insert as input in pvaIn the path where i want to sve the picture. pvaIN need as input a UNICODE string. I tryed to convert my path to a UNICODE string but every time the program return a dialog box for the location of the file (i think that is beacause there something wrong with the pvaIN) Any suggestion? i've tryed to save the image even with the "select all" and then "copy" methods to open image from the clipboard with Vision modules but nothig where put on the clipboard... WARNING!!! in the example there is a strong impact image avoid people with health problem to see it! Download File:post-1899-1154415343.vi

I need to disable it to avoid people to use the other windows application...

...ma ciao! Does anybody know how to disable the windows START button with labview? I call the user32.dll and I can disable the systray but i could not diable the START button. I'd like to disable this button even from the keyboard button.

...ma ciao! my suggestion is to reinstall all the motion utility using the Device Drivers CDs. In the past i had some similar problem due to the installation of the motion toolkit over the motion VIs include in the Device driver CDs. The "load velocity override" VI is an Advanced Trajectory Control VI. It must be in "NI Measurement->Motion->trajectory control->advanced" palette. You can load your VI ad then replace the error with this vi!

...ma ciao! i'm going to update an application that i developd with the Fingerpritn recognition toolkit foundHERE. I think that the "match fingerprint" library require a little much time. Have you ever develop any similar application? Do you think it is possible to create a similar application using NIVision? I was thinking of use "pattern matching" but my doubt is that using pattern mathcing all the fingerprint will be considered the same. Do you have any suggetsion?Can i improve my application perfomances or ihave to update this application for Xp and leave it as it is? thank you! ...ma ciao!

..Idon't know i f ican but... ...take a look at astalavista site.... you can easily avoid this license trouble!..i solve them first calling the NI assistance....but....it was quite complicated...

..ma ciao to all! I'm developing a testing machine that acquire Load from a load cell and deformation of the sample by an encoder. In some test i have to apply a constant load on the sample, so i used the PID functions to do that. The problem is that according to the sample material, i need to change the gains parameters of the PID.vi. I'd like to realize a routine that autoregulate this settings during the test. Do you think that it is possible? Do you have any suggestion on how to realize this functionality? thank youso much! ..ma ciao! Geppo!
