Exit Script

[JKLINE]

I've looked around for a way to exit the script when the user hits the 'escape' key but failed to find a solution.

Can't use 'console.readKey' because Mastercam doesn't have a console.

I also found Mcamreturn (escape pressed) and looked into the UIevents

I found this but it looks like it's pressing the keys, not waiting for keys to be pressed.

//so, I press escape key 3 times or more....
for(int i=0;i<3;i++)
{
keybd_event(VK_ESCAPE, 0, 0, 0);
keybd_event(VK_ESCAPE, 0, KEYEVENTF_KEYUP, 0);
}

you can create a loop :

while(true)

{



//if u want t exit 

break;

};

 

or better exception handling

try

{





//if u want to exit

throw new System.Exception("Exit called");







}

catch(System.Exception e)

{



}

you can also define a function in the script then consume it, remember , in a script you are inside a class of sorts and can define functions in the class

//main script procedure
bool MyScriptProc()
{



//when u want to exit
return false;

}


//call the script function

MyScriptProc();

While (escape key is not pressed){

--commit CHook--

}

return

 

This was my initial thought, but I can't get it to recognize when the escape key is pressed.

I don't want it to exit at a specific time, I want it to exit when the user presses escape.

You have to wrangle the function using pinvoke for GetAsyncKeyState

try this

 

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern short GetAsyncKeyState(int vKey);
//exit when the escape key is pressed
		while ((GetAsyncKeyState(0x1B) & 0x8000) == 0)
					{
						
						
					}

That looks like the exact thing I'm looking for

Thank you.

-- It doesn't work while waiting on user Input though.

"oh no, I've clicked the wrong geometry, I'd like to exit instead of having to go through the rest of the motions."

 

Thinking "if response == null, return"?

maybe this?

if(response == null)

{

//exit the loop

break;

}

                    if (selectedCutChain == null)
                    {
                        return;
                    }
                    DialogManager.AskForNumber("Enter Depth", ref depth);
                    if (depth == null)
                    {
                        return;
                    }
                    DialogManager.AskForAngle("Enter Rough Angle", ref roughAngle);
                    if (roughAngle == null)
                    {
                        return;
                    }
                    DialogManager.AskForAngle("Enter Finish Angle", ref finishAngle);
                    if (finishAngle == null)
                    {
                        return;
                    }

Agreed. Except depth, roughAngle, and finishAngle will never be null

Solution ::

                var depth = -0.100;
                var roughAngle = 15.0;
                var finishAngle = 20.0;
                var selectedCutChain = ChainManager.GetMultipleChains("Select Geometry");
                if (selectedCutChain == null)
                {
                    return;
                }
                var depthDialog = DialogManager.AskForNumber("Enter Depth", ref depth);
                if (depthDialog == 0)
                {
                    return;
                }
                    var roughAngleDialog = DialogManager.AskForAngle("Enter Rough Angle", ref roughAngle);
                if (roughAngleDialog == 0)
                {
                    return;
                }
                var finishAngleDialog = DialogManager.AskForAngle("Enter Finish Angle", ref finishAngle);
                if (finishAngleDialog == 0)
                {
                    return;
                }

If you need the UI to be responsive you need to run the message pump
