How can I modificate an exe file

[Dami]

First of all sorry for my english I'm from Spain. I've an exe file of a labview program, I think that the exe file was created with the run-time. My question is if I can change something of this program, and if I can how can I do it.Thanks.

The only practical way to change the program is by using LabView to change the source VI's.

Sorry, but I've Labview but I don't have the source VI's.I only have exe file.Do you know how to do it? Sorry for my ignorance.

Hi,
I think you can not change something in EXE file. This is because the EXE file keeps all VIs without diagrams.
The only thing you can do is to change the extansion of the file to LLB, open it with labview and look on the structure of library or view the front panels of VIs.

Good luck.

As Al said, without the source files, you can't do anything. It's really no different than trying to rewrite Excel or Word.

Thanks.But I change the extensione *.exe to *.vi and now I can open the front panel and if I click to pause a dialog box open asking me the password to see the diagram.Do you know how can I know this password??

Dami,

Change the extension of the executable from .exe to .llb Now you can use the LabVIEW development environment to open the application. Save the VIs to another location outside of the llb. The subVIs of the application will most likely have their front panels and diagrams removed, so you will not be able to edit them. However, you can substitute VIs in the application hierarchy. Find a VI that you wish to replace and create a new VI with the same name, connector pane, and inputs/outputs. Replace the old VI with the newly created VI. When you reload the application it will call the newly created VI instead of the old VI.

Good luck,

-Jim

Ok. this is fine but I can't save all removing the password because when I want to save the program ask me this password. It's impossible to know it???If it's possible how can I know it??

As you should know as a programmer labview and other compiler languages
translate the pseudo code used in vi's into real mashine code. by doing this
most of the stuff needed to describe the graphically displayable code will
be cut.
therefor it has to be clear that it couldn't be possible to edit completely
compiled code.

Ok I agree with you but I need the password and I don't remember it and without this password I can't work with the program.Do you know how to get the password?
