Evar variable in Forms

[sebba]

Hello,

I'm new here, also I am new with C# and UCCNC... I have some Mach3 and VB scripting experience but this is another story.

I am trying to make a macro which have to read the Evar variable and use it in some other functions.
I made a form, I can initially read the Evar value but finally this variable is lost.
I think is something related with public/private variables but it seems is too "early" for me to figure out how to solve this.
So, the macro is the next one:

I want it to work like this:
Entering MDI: M20000 E125
Windows popup appear (and ask for some other info, not implemented for now)
And finally do G0 X125 (Evar's value)

Code: Select all

exec.AddStatusmessage("Evar = " + Evar);

if (Evar != null)
{
AS3.Setfield (Convert.ToInt32(Evar),21111);
AS3.Validatefield(21111);
}

Button button1 = new Button();
button1.Size = new System.Drawing.Size(110, 47);
button1.Location = new System.Drawing.Point(28, 149);
button1.Text = "Press me";
button1.Click += new EventHandler(button1_Click);

Label label1 = new Label();
label1.Size = new System.Drawing.Size(57, 22);
label1.Location = new System.Drawing.Point(56, 93);
label1.AutoSize = true;
label1.Font = new System.Drawing.Font("Trebuchet MS", 12F, ((System.Drawing.FontStyle)((System.Drawing.FontStyle.Bold | System.Drawing.FontStyle.Italic))), System.Drawing.GraphicsUnit.Point, ((byte)(0)));
label1.Text = Convert.ToString(Evar);

MyForm = new Form();
MyForm.Size = new System.Drawing.Size(630, 300);   // Enter width & height of Form
MyForm.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
MyForm.Controls.Add(button1);        // Add Button1
MyForm.Controls.Add(label1);       // Add label1
MyForm.ShowDialog();

MyFunction();


#Events

Form MyForm; //This is a global variable, a Windows Form

 

void button1_Click(object sender, EventArgs e)
{
 MessageBox.Show("Evar " + Evar);  // CS0103 | in line: 57 | error text: The name 'Evar' does not exist in the current context
 MyForm.Close();
}

void MyFunction()
{
 exec.Code("G0 X" + Evar); // CS0103 | in line: 57 | error text: The name 'Evar' does not exist in the current context
}
 


It seems the Evar is "lost" after #Events and lines like "MessageBox.Show("Evar " + Evar);" or "exec.Code("G0 X" + Evar); ", are generating the CS0103 error.
How can I make this working?

Thank you very much,
Seb

Would this work?

Code: Select all

Double XPosition = Evar;

....
....
....

exec.Code("G0 X" + Evar);
while(exec.IsMoving()){}

Define a variable after the #Events, e.g. double? myevar;. Before the #Events write myevar = Evar;. The variables after the #Events are public in the macro, so you'll see them in every subroutine.

Hello, and thank you all for replies.
I tried to do this, for now no more errors appear but the new double myEvar variable seems to be null
my actual code (the last part) looks like this:

Code: Select all

myEvar = Evar;

#Events
double? myEvar;

Form MyForm; //This is a global variable, a Windows Form

void button1_Click(object sender, EventArgs e)
{
 MessageBox.Show("myEvar " + myEvar);   
 MyForm.Close();
}


the output of "MessageBox.Show("myEvar " + myEvar);" looks like this:

Also, thank you @ger21, for your input. Same issues like before.

Thank you,

See this post and search the web for "C# double? type". In the manual you'll find how to check if the Evar has value.

It work by me (I wrote M1063 E1, X moved to 1):

Code: Select all

exec.AddStatusmessage("Evar = " + Evar);

myEvar = Evar;

Button button1 = new Button();
button1.Size = new System.Drawing.Size(110, 47);
button1.Location = new System.Drawing.Point(28, 149);
button1.Text = "Press me";
button1.Click += new EventHandler(button1_Click);

Label label1 = new Label();
label1.Size = new System.Drawing.Size(57, 22);
label1.Location = new System.Drawing.Point(56, 93);
label1.AutoSize = true;
label1.Font = new System.Drawing.Font("Trebuchet MS", 12F, ((System.Drawing.FontStyle)((System.Drawing.FontStyle.Bold | System.Drawing.FontStyle.Italic))), System.Drawing.GraphicsUnit.Point, ((byte)(0)));
label1.Text = Convert.ToString(Evar);

MyForm = new Form();
MyForm.Size = new System.Drawing.Size(630, 300);   // Enter width & height of Form
MyForm.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
MyForm.Controls.Add(button1);        // Add Button1
MyForm.Controls.Add(label1);       // Add label1
MyForm.ShowDialog();

MyFunction();


#Events

Form MyForm; //This is a global variable, a Windows Form

double? myEvar;


void button1_Click(object sender, EventArgs e)
{
  MessageBox.Show("Evar " + myEvar);  // CS0103 | in line: 57 | error text: The name 'Evar' does not exist in the current context
  MyForm.Close();
}

void MyFunction()
{
  exec.Code("G0 X" + myEvar); // CS0103 | in line: 57 | error text: The name 'Evar' does not exist in the current context
}

Great, thank you very much!
It is working now, even mine code, after I moved "myEvar = Evar;" in the first lines of code...

Best regards,
Seb
