Thanks Norm Kirchner, We are going to use FPGA, where mostly use ARM 32bit AtMega microcontroller IP block. Can we have Real Time Operating System on our microcontroller and can we run LabVIEW web server inside that( i.e. I mean Embedded Web Server )? On this server root there will be VIs & html files which will call those VIs. Is this possible? As per your answer it is not possible to have LabVIEW web server without the PC?

Hi, We are in a stage to decide the technology to use for Web Application. We have our on instrument which will have embedded web server on it. And through internet, it will be accessed through remote computer. Question: (1) Does LabVIEW Web Server can be embedded into the microcontroller ? (2) On server side( on our instrument ) is there anything require other than Embedded Web Server? Or anything that need to be considered? (3) On client side, as per I know, it is required LabVIEW runtime environment. Is there any thing else that might require to consider. (4) Please let me know the issues & limitations for embedded web server and remote application in LabVIEW. Thanks in advance.

Hi, We are making one device, which will have its own Embedded Web Server as an IP block in FPGA. On that server there will be some html files. And this files will be opened on the Internet Explorer etc when we will connect that device to internet. Now, the question is: We want to call the LabVIEW VI from HTML file. With the current LabVIEW 8.20 software I have, I can generate html file for LabVIEW front panel using Web Publicing Tool. I read on the internet about G Web Server. But I am not cleared that, can this G Web Server be embedded in any microcontroller we use in our circuit? Or we require to do something else for that. We will embedded that Web Server in our microcontroller. Our html files(with VI inside that) will be placed on that Embedded Server. We will connect that device to internet and we will type the address to open that html page with VI on the internet explorer. Is it possible? Can G Web Server be embedded to the any microcontroller? Where can I get the detailed information about all the requirements and configurations? Thanks, Regards, Prashant Patel

But when I save the VI and open it again and if I look the path in the "Configure" option then it will again turn to full path of my system. Now If I will distribute this VI then on the other computer, it will search again for that DLL when ever user open it first time. I want it to take from same folder directly. Thanks

Hi... I am using LabVIEW Version 6i. I made one library which is using Call Library Function(i.e. DLL) in three VIs. When I set relative path ".\MY_DLL.dll" in the configuration of Call Library Function then it is chaging it to absolute path (e.g. C:\Program Files\National Instruments\LabVIEW 6\user.lib\My_Folder\My_DLL.dll ) automatically. I want it relative so that when user put my_llb.llb file and my_dll.dll file into "\user.lib\My_Folder" folder then it will automatically take that dll instead of searching for that DLL in the nearest location. What should I do? Thanks..

Hi.... I have made three subVIs and want to distribute as LabVIEW library. I made a llb file and added all three sbVIs in that. And put it in user.lib. In all three dll there are Call Library Function means I have one dll. I have put this DLL in the use.lib folder. Problem: The icon and name of my application in the LabVIEW "User Libraries" pallete are default. I want it to set automatically set to my desire icon for that subpallete and desire name as well. How can I do that? I am using LabVIEW 6i. I tried to change the icon and name. And I tried according to following link and in the third step it says "Right-click an icon in the custom view and remove the checkmark next to Synchronize with Directory in the shortcut menu." But that option is greyed out, how can I remove checkmark against that. http://digital.ni.com/public.nsf/3efedde43...enDocument#rank I also tried to rename readonly.txt file in default folder in menu folder. I tried to add in default folder but it does not sucess. It is always giving error that please check the read only attribute. One Dll is used in all three subVIs. When I set relative path ".\MY_DLL.dll" in the configuration of Call Library Function then it is chaging it to absolute path automatically. I want it relative so that when user put my_llb.llb file and my_dll.dll file into user.lib folder then it will automatically take that dll instead of searching for that DLL in the nearest location. What should I do? Do I require to buy Application Builder for that-specially for setting my own icon & name for "subPallete" of my library. Thanks in advance......

Thanks for reply. I want to make subVI so gleichman is right. I have to make shift register. I tried to make one but as I am new to LabVIEW. I am not getting success. I know it is very basic but don't know, why I can't make it happen? Is there anybody who can send me simple subVI in which (may be using Shift Register) some portion of code can be called once even though the subVI is in the while loop when that subVI will be used. Thanks in advance.......

Hi.. I have made one VI. In which some portion of code I want to execute only once. For that I have made one case statement. First time case condition is true and desire code is executed. But how can I stop executing that code second time. Means second time I want to make case condition variable false. How can I do that? Thanks in advance.......

QUOTE(smenjoulet @ Feb 8 2007, 02:27 PM) Thanks everybody for reply. Yes, If we recompile the VIs then it is working. But we are doing this starting from version 4.0 . And we have to give all the VIs compiled from different versions to user. So this is little bit confusing for user and bad way of programming as well. So we have decided to convert CIN to DLL and compile the VI using version 4.0 . So the same VIs will be given to user and he can use it for what ever version he want. But as Rolfk said let me see if we use labviewv.lib or labview.lib then problem will be solved or not? Thanks..

Hi, We got three CINs in our project and we are using that to make library for our products. The problem is, if we have compile it using version 7 and if user have version 6 or 8.20 then those CINs can't be used. For that we have to make .lsb file and compile using perticular version i.e. If user have version 6 then we have to compile our c file in that version and give it to user. So for every version we have different .lsb file for same c file. Is there any way we can use the same .lsb file for all the version. Thanks in advance.....

Hi, Can anybody help..plz... Brief Background: I want to make our own functions and add it to user library under our defined subpallete. I got version 8.20 . And I have all ready developed one test function which is using Call Library Function Node and get the data and display. And added under user library->Tect_Lc subpallete. Questions: (1) User can have any version of LabVIEW. Is there anyway to build this library so that it can be used in older versions of LabVIEW without midifying? If it is not possible then what best we can do? (2) How can I make an installation version which can detect whether LabVIEW is installed in a perticular PC or not? If yes, then add Test_LC subpellet under User Library it self which will have our subVIs under it? Is it all possible with Application Builder? Because we don't have application builder so if it is really require then we want to buy that? Thanks,

Thanks for Reply Rolf Kalbermatter Sorry by static class, I meant static class instance. e.g. For class My_Class, If I use following statement static My_Class mc; Will this be work ? And you said : "writing standard C function wrappers to all the methods of your static class and export them from your DLL" Please let me know, what should I do to write standard C function wrappers? I understand export from DLL. But confuse with wrapper. And the question is, will it make my class instance same as static. If I open different exe file and load dll file in that then it should get the same instance (or same memory space as static) of static My_Class mc; Thanks,

Hi, We have a big library written in C. And we want to use that library into LabVIEW. I know that if we make DLL and call that DLL into LabVIEW, that is the best option. But the problem is there are some static class and data defined in three files. Problem is, if we use DLL then static class will not work with DLL. Is there any way we can use this static class and data into LabVIEW but they still be static e.g. ActiveX or Any other. I also know that we can create CIN but the problem is we have to do quite a lot addtional work and if the user will have the different versions of LabVIEW then we have to again build CIN for that version and distribute. And that is again not practical solution. Any help appreciated. Thanks..
