We’re trying to launch an exe on a button click in kinetic (client, not web). It works in our old classic customization, but that was written in vb. I have the code in a function that runs on button click, and I was trying to run notepad just to get any exe working, but nothing happens. I can confirm that the function is being called and the filepath is correct. Code below. Any ideas?
var process = new System.Diagnostics.Process();
process.StartInfo.FileName = @"notepad.exe";
process.StartInfo.WorkingDirectory = @"C:\Windows\system32\";
process.Start();
private void epiButtonC1_Click(object sender, System.EventArgs args)
{
// ** Place Event Handling Code Here **
// Prepare the process to run
var process = new System.Diagnostics.Process();
ProcessStartInfo start = new ProcessStartInfo();
start.FileName = @"notepad.exe";
process.StartInfo.WorkingDirectory = @"C:\Windows\system32\";
int exitCode;
using (Process proc = Process.Start(start))
{
proc.WaitForExit();
// Retrieve the app's exit code
exitCode = proc.ExitCode;
}
}
Thanks for the quick reply.
I tried copying your code, but it just runs forever without opening notepad.
I’m writing the function in Epicor Functions Maintenance and calling it with the erp-function widget in application studio on button click.
Yes, with restrictions. You will have to register a custom url handler on the workstation.
To “launch” the app, you will provide a link, that the handler will open.
Based on your original post, it sounds like you had the code in the UI since you mentioned VB.
To do it locally, you could still do it in the UI with the code I gave.
I’m going to postulate that you’re moving to to a function to be reused without copying code around to each screen? Or is there another reason you’re moving it to a function?
I wasn’t aware of another way to execute code (from user-interaction like a button click) in the kinetic style screens other than to put it in a function (from Epicor Functions Maintenance). The VB was from our old customizations in E10 that were all on classic-style screens that we’re trying to convert to kinetic-style now that we’ve upgraded to E11.
Ah, okay–that makes sense.
So, as far as I know there’s no way to do this in a friendly way in App Studio.
There’s a pretty big security risk if a web browser application would allow an executable to launch on the client machine.
I’ll defer to @klincecum since I don’t know anything about custom URL handlers.
Whenever you get that set up, there’s a url-open widget that can launch URLs.
That should probably do the trick after the url handler is set up.
I haven’t messed with it in a while, but I’ll see if I can find some relevant and
modern documentation.
It opened Notepad. Have you not been following along
However this statement:
“I’m writing the function in Epicor Functions Maintenance and calling it with the erp-function widget in application studio on button click.”
Does not support this statement:
“in kinetic (client, not web).”
We had created what amounted to external “epicor” screens (basically winforms exes or similar), which supplemented the functionality of epicor. By having these open from our customization, it made it easier to run them for our users, and then the screen could also close when epicor closes (instead of users having to close them all manually).
And if the functionality MUST be in an external app, can you convert those programs to web apps (using Web Forms maybe)? This would make it easier to integrate with Kinetic UI. It would make deployments much, much easier as well.
