Question

I’ve got this code in a pair of button click event handlers on a C# form:

class frmLogin {     private const int SHORT_HEIGHT = 120;     private const int LONG_HEIGHT = 220;      private EventHandler ExpandHandler;     private EventHandler ShrinkHandler;      public frmLogin()     {         InitializeComponent();         ExpandHandler = new EventHandler(btnExpand_Click);         ShrinkHandler = new EventHandler(btnShrink_Click);         btnExpand.Click += ExpandHandler;     }      private void btnExpand_Click(object sender, EventArgs e)         {         this.Height = LONG_HEIGHT;         btnExpand.Text = '<< Hide Server';         btnExpand.Click -= ExpandHandler;         btnExpand.Click += ShrinkHandler;     }      private void btnShrink_Click(object sender, EventArgs e)     {         this.Height = SHORT_HEIGHT;         btnExpand.Text = 'Choose Server >>';         btnExpand.Click -= ShrinkHandler;         btnExpand.Click += ExpandHandler;     } } 

The text change occurs without issue, but on one particular client machine, a Dell M4300 laptop workstation, the height change does not take effect. Has anyone resolved a similar issue, and what was the fix if so?

Answer 1

My guess: The DPI or system font size is different on that machine and your form’s AutoScaleMode is either ‘Font’ or ‘Dpi’, making your form’s MinimumSize or MaximumSize prevent the change.
