لكني لم اقصد هذا بل قصدت عند الضغط على نفس الاداة وتحريكها فوق اداة اخرى
وضعت مثال لذلك
لكن المثال عملته بطريقة اخرى لعدم تمكني من عمل ما اريد
اريد عند تحريك اداة Button فوق اداة TextBox بمجرد دخول اداة Button فوق اداة Textbox يتم وضع
اداة الـ Button فوق اداة Textbox حسب الـ Location لاداة TextBox
شاهد المثال وستعرف قصدي
المثال اضغط على اداة الـ Button سيتغير لونه ثم اضغط على احد مربعات النصوص وشاهد سينتقل الـ Button فوقه مباشرة
لكني اريده بالضغط والافلات فوق التكست بوكس
السلام عليكم،
تم التعديل على الكود ليعمل كما تريد

لكن ليس هذا ما قصدت تحريك الاداه هذا جميل جداً لكن اريد بعد تحريك الاداة من خلال
السحب ومرورها فوق التكست بمجرد دخولها فوق التكست والافلات يتم لصق الاداة فوق التكست
في مشروع الأخ DreamsDotNet إستبدل الأمر الموجود في Button1_MouseUp بالأمر التالي :
كود :
Private Sub Button1_MouseUp(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseUp
Button1.Cursor = Cursors.Default
Dim P As Point = (Button1.Location + e.Location)
If P.X >= TextBox1.Left AndAlso P.X <= TextBox1.Left + TextBox1.Width Then
If P.Y >= TextBox1.Top AndAlso P.Y <= TextBox1.Top + TextBox1.Height Then
TextBox1.Controls.Add(Button1)
Button1.Dock = DockStyle.Fill
End If
End If
End Sub
