how to display vi ,when vc calls labview dll

[sarali]

i create a vi for detecting use,and build it as a dll, before this ,i changed the vi  appearence,

i'd like to make vc(for example ,a button) call this labview dll to display the detecting process and result ,

i add the .h,.lib files ,move the .dll file to the program folder, building passed,but it can't display vi.

i don't know why,and i really need your help.

If you changed your VI to a DLL you should not be worried about how it looks.  A DLL is the "behind the scenes" code without the GUI (user interface).  This has been removed and should be supplied by the calling program.

Another choice for distributing code is to build your VI into an executable or .EXE file.  This will fully retain the front panel and allow you to run the VI without the development environment.

Which one of these are you trying to accomplish...?....run program on target machine by itself...OR....use LabVIEW code behind a visual C UI...???

You asked the exact same question in another thread. I've never called a LabVIEW DLL from c++ but I do call a DLL from TestStand and am able to display the front panel. How exactly did you change the VI appearance? Maybe if you posted the VI and the .bld file you're using, some more help could be given.

Also, there's no reason to start a new thread. In the other thread, you didn't answer the last question asked of you. Multiple threads just confuse things even more.
