C＃工具提示問題

Question

我有以下代碼，可以對位於表格內的圖片框進行圖片翻轉。每個表格單元格中都有一個圖片框。

問題是即使在代碼中聲明不應該顯示圖片框上的工具提示，不知何故某些工具提示出現。我不能在代碼中找到它，因爲代碼沒有指定任何工具提示！

我已經嘗試了幾種方法，但他們似乎都使用工具提示collasp ..是否有工具提示控件中的已知錯誤？

private bool deployingShip = false; 

    private void PictureBox_MouseEnter(object sender, EventArgs e) 
    { 
     PictureBox HomeCurrentPicBox = ((PictureBox)(sender)); 
     TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox); 

     RefreshHomeGrid(); 

     if (deployingShip == false) 
     { 
      if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.Water) 
      { 
       HomeTableLayoutPanel.Cursor = Cursors.Hand; 
       HomeCurrentPicBox.Image = Properties.Resources.Scan; 
       HomeCurrentPicBox.Refresh(); 
      } 
      else 
      { 
       HomeTableLayoutPanel.Cursor = Cursors.No; 
       HomeTableLayoutPanel.Refresh(); 
      } 
      gameFormToolTip.SetToolTip(HomeCurrentPicBox, GameModel.alphaCoords(HomeCurrentPosition.Column) + "," + HomeCurrentPosition.Row); 
     } 

     if (deployingShip == true) 
     { 
      Cell.cellState state = GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row); 
      switch (state) 
      { 
       case Cell.cellState.Origin: 
        HomeTableLayoutPanel.Cursor = Cursors.Hand; 
        gameFormToolTip.SetToolTip(HomeCurrentPicBox, currentShip.ToString() + ": " + Cell.cellState.Origin); 
        break; 

       case Cell.cellState.EndPoint: 
        HomeTableLayoutPanel.Cursor = Cursors.Hand; 
        gameFormToolTip.SetToolTip(HomeCurrentPicBox, currentShip.ToString() + ": " + Cell.cellState.EndPoint); 
        break; 
       default: 
        HomeTableLayoutPanel.Cursor = Cursors.No; 
        HomeTableLayoutPanel.Refresh(); 
        return; 
      } 
     } 
    } 

    private void PictureBox_MouseLeave(object sender, EventArgs e) 
    { 
     PictureBox HomeCurrentPicBox = ((PictureBox)(sender)); 
     TableLayoutPanelCellPosition HomeCurrentPosition = HomeTableLayoutPanel.GetCellPosition(HomeCurrentPicBox); 

     if (GameModel.HomeCellStatus(HomeCurrentPosition.Column, HomeCurrentPosition.Row) == Cell.cellState.Water) 
     { 
      HomeCurrentPicBox.Image = Properties.Resources.Water; 
      HomeCurrentPicBox.Refresh(); 
     } 
    } 

謝謝你，我怕你將無法從該提交的代碼:(找到了這個錯誤

你錯過了電話從提示明確刪除舊的價值觀？基於代碼，我「M猜測它可能會在MouseLeave事件處理程序的歸屬。

gameFormToolTip.SetToolTip(HomeCurrentPicBox, "");
