Is there an easy way to set the zoom level for a windows form in C#? In VBA there was a zoom property of the form.
A:
Can you specify what kind of form? Are we talking about web forms and text encoding sizes?

A:
There is no way (that I know of) to do what you ask with typical WinForms.
If you're doing custom painting/drawing, you can zoom that by using a zoom transform, but so far as I know there is no "Zoom" property for the form in the entire world of .NET and native Windows/C++ APIs combined.
You could probably rig something yourself such that you scale controls by a constant factor. And you can probably find 3rd-party controls/surfaces which support this. And who knows what is possible with WPF. But in a typical WinForms world, no.

Here is the method: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.scale.aspx. Of course you shall keep track of original controls size since after having scaled controls their scaled value is approximated to an integer value (so, successive zoom in-out operation may lead to incorrect original sizes).

I agree with @CodingTheWheel. Unless you are doing this in WPF, traditional windowsforms have no automated way of "zooming in" without having to iterate through all controls and manually jacking up their sizes.

I had the same problem and I solved this way in c#. Code goes on Form load
float scaleX = ((float)Screen.PrimaryScreen.WorkingArea.Width / 1024); float scaleY = ((float)Screen.PrimaryScreen.WorkingArea.Height / 768); SizeF aSf = new SizeF(scaleX, scaleY); this.Scale(aSf);
This "more or less" scales form and all children. Loops forever in 800x600 (?) You have to set the following Form properties
AutoscaleMode = Font AutoSize = False
Hope this helps, Fabrizio
