| Quote: | io.popen takes two params:
1.) File to launch.
2.) Access flags.
For example if you want to read from the launched process:
local filehandle = io.popen( "C:\\somefolder\\someapp.exe", "r" ); |
I don't know what to do. by it code can launch a game' executable file?
my script for launch game is:
| Code: | function LaunchClick()
filetolaunch=openDialog_execute(Trainer_OD)
if filetolaunch~='' then
io.popen( filetolaunch, "r" );
end
end |
and i don't know why its not worked. 
can you help me?

and you're sure that that exe is the same exe as the shortcut on your desktop?
E.g: It could be there is a launcher.exe which actually starts the game

I'm sure.
the game have one executable file. when i try to run the game by shellExecute(), I'm faced with this problem but when i run trainer and run the game with double click on the shortcut, i haven't any problem and the game work correctly.
As i said before i just in some games I'm faced with this problem.
If you can give me another code that does this code work.

Right-click the shortcut and choose 'Properties'. Check the paths to see if there are any extra arguments you need to pass for the game to even open.

Look at the photo, there is nothing to do. I know what you're looking for, but there is nothing there.

popen doesn't seem to launch the file but rather suspend it in memory.
You can use createProcess if you want to have CE load the file and auto-attach to it for you though.
For example:
| Code: | | createProcess( "C:\\Windows\\system32\\winmine.exe" ); |

I do not want the code for CE. I want the code for the trainer. Does this code also work?

I don't know if createProcess() works in trainers as I don't use the CE trainer maker. shellExecute() should work fine as long as you pass the full path properly.
For example:
| Code: | | shellExecute( "C:\\some_folder\\some_file.exe" ); |
Works fine for me. As for openDialog_execute, it doesn't appear that DB exposed any method to create a dialog yet. Looking at the source, it expects a dialog object since it casts back from a userdata object but there isn't a way to construct a FileDialog yet.

opendialog gets created if you put it on a form (it's a lot easier to configure a opendialog using the property editor as well)

Think of popen as a command line.
You can start another process using things like:
| Code: | | local f = io.popen( '"C:\\some_folder\\some_file.exe"', "r" ); |
Given that a command window will stay open during the duration of that files handle being valid. (Lua launches the other process separately.)
You are better off sticking to shellExecute though.

The code worked very well but I had a question.
How can I make this code placed in the following code?
| Code: | function LaunchClick()
filetolaunch=openDialog_execute(Trainer_OD)
if filetolaunch~='' then
local f = io.popen( ????, "r" );
end
end |

Just throws access violations for me.

wiccaan:
remember that the name of the opendialog object will be formname+opendialog (check if it's nil or not)
and then you can show it using openDialog_execute(formname_dialogname)
iron soft:
Try:
local f = io.popen( filetolaunch, "r" );
or
local f = io.popen( '"'..filetolaunch..'"', "r" );

Yeah, I did. It's still throwing access violations regardless. I'm trying it through the raw Lua panel as well as the editor. With the editor I'm doing:
1. Open CE -> Generate Trainer
2. Rename form to something noticable such as frmExampleTrainer
3. Create a button and name it btnLaunch.
4. Create an OpenDialog and name it odExampleTrainer.
5. Set the onClick even using ... twice to open the editor and create the event.
6. Set the code as the following for the click event:
| Code: |
function btnLaunchClick(sender)
local child1 = control_getParent( sender ); -- button to panel
local child2 = control_getParent( child1 ); -- panel to form
if( frmExampleTrainer_odExampleTrainer == nil ) then
print( "its nil" );
end
local dlg = openDialog_execute( "frmExampleTrainer_odExampleTrainer" );
end
|
Which just throws an access violation on the openDialog_execute. I did the getParent method just to ensure it was getting the correct name for the form. Manually entering the name doesn't help.
The check works fine, and printing out info on the object works so it is valid, but the dialog still fails.
