NSError err = new NSError();

THis is not allowed anymore, just do this

NSError err;

The function taking it with an ‘out’ will create it.

OK I figured it out! Here is what you need to do:

in the beginning tell RB to use UTF8:
s = s.DefineEncoding(Encodings.UTF8)

Then replace ALL calls to
Len with LenB
Mid with MidB
Right with RightB
Asc with AscB

that did the trick for me and made ShowURL work properly.

Thanks for the nice code-snippet. But it is not working with special characters like ü. It gives %FC as a result, but to make RBs ShowURL work, you will need UTF8 ecoding which gives %C3%BC as a result. But I haven’s figured out how to accomplish this.

Hi Frank, I'm not sure what might be causing your issue but I would go ask in the Xamarin site. They recently took over all support from Novell.

Hello,
I find your blog by searching for “ShowTextAtPoint”. We are using a similar method for text output on a graphic context.
But we have the problem that german umlaute are not displayed (they are replaced by other characters).
Unfortunately, we didn´t get any support from novell (neither any answer).

Do you have any idea, if this is a general problem by monotouch classes?

Thanks for any help.

Frank

Hai,

Thank’s for the tutorial.
I am new to monodevelop.I created a signature project using core graphics.The project uses touches began event and mouse coordinates to draw.When i draw slowly the coordinates are highlighting but when the mouse moves faster there is a gap between adjacent coordinates.Please help..

Here is the code.
var currentPoint = new PointF();
var lastPoint = new PointF();
UITouch touch = touches.AnyObject as UITouch;
currentPoint = touch.LocationInView(this);
currentPoint.Y -= 7;
UIGraphics.BeginImageContext(this.Frame.Size);
CGContext cont = UIGraphics.GetCurrentContext();
if (this.Image != null)
{
cont.TranslateCTM(0f, this.Frame.Size.Height);
cont.ScaleCTM(1.0f, -1.0f);
cont.DrawImage(new RectangleF(0, 0, this.Frame.Size.Width, this.Frame.Size.Height), this.Image.CGImage);
cont.ScaleCTM(1.0f, -1.0f);
cont.TranslateCTM(0f, -this.Frame.Size.Height);
}
cont.SetLineCap(CGLineCap.Round);
cont.SetLineWidth(3f);
cont.SetRGBStrokeColor(0f,0f,0f,1.00f);
cont.BeginPath();
cont.MoveTo(currentPoint.X, currentPoint.Y);
cont.AddLineToPoint(currentPoint.X,currentPoint.Y+5);
cont.DrawPath(CGPathDrawingMode.Stroke);
this.Image = UIGraphics.GetImageFromCurrentImageContext();
UIGraphics.EndImageContext();
lastPoint = currentPoint;
NSError err = new NSError();
string img_path=”path”;
this.Image.AsJPEG().Save(img_path,true, out err);

This is a really good online URL encoder –

It’s a good place to test your own code against. Watch out for accents and unicode characters! They can be tricky to get right.

Thank you very much for this code snippet!
