mousemove关于mousedown、mouseup、mousemove、C#

VB怎么调用 Mousemove

我估计您是这个意思， 双击要调用mousemove的控件，进入之后默认右上角为click，下拉菜单里找到mousemove使用就行， 具体形式见2楼和1楼组合，如下（参照） （ 我举个例子：按键钮原本的颜色是黑色，当滑鼠碰到时就变成红色了，移开之后又变黑。

Private Sub label1_MouseMove(Button As Integer, Shift As Integer, X As Single, y As Single) Label1.ForeColor = vbRed End Sub —————————————————————————————————— Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single) Label1.ForeColor = vbblack End Sub ）

关于mousedown、mouseup、mousemove、C#

在add之前先remove掉就行了： private void toolStripButton3_Click_1(object sender, EventArgs e) { this.pbImg.MouseDown -= new MouseEventHandler(FillCircle_MouseDown); this.pbImg.MouseUp -= new MouseEventHandler(FillCircle_MouseUp); this.pbImg.MouseMove -= new MouseEventHandler(FillCircle_MouseMove); this.pbImg.MouseDown += new MouseEventHandler(toolStripButton3_MouseDown); this.pbImg.MouseUp += new MouseEventHandler(toolStripButton3_MouseUp); this.pbImg.MouseMove += new MouseEventHandler(toolStripButton3_MouseMove); } private void FillCircle_Click(object sender, EventArgs e) { this.pbImg.MouseDown -= new MouseEventHandler(toolStripButton3_MouseDown); this.pbImg.MouseUp -= new MouseEventHandler(toolStripButton3_MouseUp); this.pbImg.MouseMove -= new MouseEventHandler(toolStripButton3_MouseMove); this.pbImg.MouseDown += new MouseEventHandler(FillCircle_MouseDown); this.pbImg.MouseUp += new MouseEventHandler(FillCircle_MouseUp); this.pbImg.MouseMove += new MouseEventHandler(FillCircle_MouseMove); } }
