私のWP7
アプリでInvalidOperationException
は、デバイスでスローされています(エミュレーターでは正常に動作しています)。が提供するスタックトレースからMicrosoft
、ソースは次のコードのようです。
Image start_rec = (Image)FindName(start_name);
// Return the general transform for the specified visual object.
GeneralTransform generalTransform1 = canvas1.TransformToVisual(start_rec);
pt = generalTransform1.Transform(new Point(0, 0));
double start_y = pt.Y * (-1);
double start_x = pt.X * (-1);
Image destination_rec = (Image)FindName("dot" + destination_name);
// Return the general transform for the specified visual object.
generalTransform1 = canvas1.TransformToVisual(destination_rec);
// Retrieve the point value relative to the child.
pt = generalTransform1.Transform(new Point(0, 0));
double destination_y = pt.Y * (-1);
double destination_x = pt.X * (-1);
上記のコードでやろうとしていること:に画像がありcanvas1
ます。キャンバスに対する画像の場所を取得しようとしています。
私の質問は、なぜ私がException
?を取得しているのかということです。
