How can I call a LabVIEW executable from within another LabVIEW executable?

I have a customer requirement for two LabVIEW executables. Based on their current setup, they need to run executable "A" or "B", both of which are under independent revision control. I have created a third "selection" executable that allows the operator to choose between one of the two, but I am receiving errors when I attempt to call a LabVIEW executable from within a LabVIEW executable using either the "System exec" VI or the "Run Application" VI. If I call a non-LabVIEW executable (such as Windows Explorer) everything works fine.

As with the other poster, I suspect a path problem. You might try the
path out in a shell window, and if it works, copy the complete absolute
path to LV to see if that works. LV is basically passing the comma
nd to
the OS and doesn't even know what is in it, so you should be able to get
it to work.
The other poster commented on subpanels, which is a good suggestion, but
without going to LV7, an EXE can have open more than one VI. You can
use the VI Server and the Run method to fire up another top-level VI.
The decision is whether you want both to be in unique processes.

How can I call a java class from within my program?

I was wondering if there's a platform independent way to call a java class from my program.

Here's my scenario. I'm working on a platform independent, feature rich, object-oriented command prompt program. The way I'm designing it is that users can drop classes they write into my bin directory and gain access to the class through my program. For example, they drop a class named Network.class in the bin directory. They would type Network network at my command prompt and gain access to all the methods available in that class. They can then type system.echo network.ipaddress() at my prompt and get the system's ip address. I have it designed that there's a server running in the background and the clients connect to my port. Once connected the end-user can enter their user name and password and gain access to the system. When they type a command they actually call another java program which connects to my server using a seperate thread. They can then communicate back and forth. I have it set that everything has a process id and it's used to keep track of who called what program. Once the program is done it disconnects and closes. Rather than getting into the nitty gritty (I didn't want to get into heavy detail, I know how everything will work) I'm really interested in finding out how I can call a java program from my program. I don't want it to be part of the app in any way.

Need help to call a simple function from within another function?

I created a movieclip which has a function in its one and only frame.
function testx() {
x = x+2};
This movieclip is in the main timeline (in its own layer).
In another layer on the timeline I have created a single keyframe with a button instance called myBtn
myBtn.onRelease = function() {
var x
x =2
testx(2);
trace (x);
What I want to do is call the function in the movieclip frame from the button press function. However, I can't seem to reference it properly.
Can anyone help me to basically call a simple function from within another function?

Yes am using CS4. Have saved it as CS3 now. Ok the file is somewhat complicated and what I am testing is not what I ultimately want to do but if I can pass that variable I can figure it out. In terms of describing the file I think the only parts of importance are what I put in my previous post (please let me know if there is something I should be telling you that I have missed). I am 99.9% sure that I am using the correct instance name.
Scene1 Layer3 Frame1 has the function call for the button.
myBtn.onRelease = function() {
var x
x = 2
testx(2);
trace (x);
Slideshow layer //Actions Frame1 has the function
function testx(x) {
x = x+2};
thank you so much for helping me.

How can i call a DLL file from labview?

Iam using a sensoray 2601 module.It is given as DLL file(S2600.DLL).How can i call this function from LabVIEW?
Please Mark the solution as accepted if your problem is solved and donate kudoes

As far as I can tell problems might occur with the call library function node if the the DLL from visual basic is actually an ActiveX dll if that is the case it seems calling the dll by using the Invoke node is the way to go.

Can you call a function module from within a smartform?

I was told that yu can not call a function module from a smartform - that does not make sense to me because you can do tons of ABAP within a smartform.
Well - can you?
Thanks.

Yes, you can call function modules.
