Visual Basic 2010 Clearing a Picture Box
提问by HashHazard
Im trying to build a simple poker game in visual basic studio 2010. When I click btnShuffle I assign the five image place holders the default backside of the card
我试图在 Visual Basic Studio 2010 中构建一个简单的扑克游戏。当我单击 btnShuffle 时，我将五个图像占位符指定为卡片的默认背面
btnShuffle_onClick......
picFlop1.Image = My.Resources.BlankCard //saved in my resources folder
picFlop2.Image = My.Resources.BlankCard //and so on and so on...
end sub
and then in my btnDeal cards I have tried every version of picFlop1.Dispose(), picFlop1.Image = Nothing... etc that I can find and nothing seems to erase the blank image.. I've tried skipping the clear step and just writing the actual face card overtop of the blank card, but it doesn't seem to show threw the initial blank card.. any help would be great..
然后在我的 btnDeal 卡中，我尝试了所有版本的 picFlop1.Dispose()、picFlop1.Image = Nothing... 等等，我可以找到并且似乎没有任何东西可以擦除空白图像.. 我试过跳过清除步骤和只是将实际的人脸卡写在空白卡的上面，但它似乎没有显示抛出了最初的空白卡..任何帮助都会很棒..
btnDeal_onClick...
//find first five cards on deck and assign them by overwrite/delete blank card
picflop1.Image = My.Resource.SomeCard //Does Not Work
picFlop1.Image.Dispose() //Does Not Work
picFlop1.Image = Nothing //Does Not Work
end sub
UPDATE
更新
I am assigning these blank cards... not in the shuffle function but in the timer1 interval function.. could that have anything to do with it? The methods listed above work in a btnReset_onClick
我正在分配这些空白卡......不是在随机播放功能中，而是在 timer1 间隔功能中..这与它有什么关系吗？上面列出的方法在 btnReset_onClick 中工作

Good call on looking closer at the timer @LarsTech..
很好地呼吁仔细观察计时器@LarsTech ..
Apparently if you don't stop the timer, it will continuously kick out the code to display the backs of the cards.. all the other code was functioning fine, just couldn't see it bc of the timer... Thanks guys.. as always.. your the best!
显然，如果你不停止计时器，它会不断踢出代码以显示卡片的背面..所有其他代码都运行良好，只是在计时器之前看不到它......谢谢大家。 . 一如既往.. 你是最好的！

How about?
怎么样？
PictureBox1.Image = New Image
回答by BrainStorm.exe
Assuming that picFlip is a PictureBox, have you tried Invalidate() and then Update() after setting the new image?
假设picFlip是一个PictureBox，你有没有在设置新图像后尝试过Invalidate()和Update()？
回答by Daniel Abou Chleih
You have to
你必须
PictureBox.Image = null
After that you can set a new image
之后，您可以设置新图像
