button

问题 I have a button which I wanted to "flash" briefly to get the user's attention. I figured the easiest way would be to change the Button's BackColor property to another color, and then switch it back again. So I do something like this: this.oldColor = myButton.BackColor; myButton.BackColor = Color.Blue; and then after a about 1/2 a second: myButton.BackColor = this.oldColor; But the button's background color end up being distinctly darker than the rest of the buttons on the Form! At first, I

问题 Currently assigned the task of creating a website which uses python to visualize a network. With this, after clicking a button, the python script will run off of specific parameters the user sets. To avoid a huge load request, we only want the user to click the button once, and not be able to run the script multiple times. The idea we came up with was having the button be clicked once, and then after the one request, become disabled(until they refresh the page, although I know they can just

问题 Here: http://msdn.microsoft.com/en-us/library/hkkb40tf(v=VS.90).aspx, it says that, to call a button's click event from another button, you can/should do it this way: button1.PerformClick(); However, in my situation (VS 2003. NET 1.1), this doesn't compile (admittedly, the link above specifies VS 2008, but it does not have a link to the pertinent info for prior versions, as msdn often does). This compiles: private void btnPrint_Click(object sender, System.EventArgs args) { if (this

问题 So I have an image button and I want to have two states on it. It will work like a bookmark button which has two states. If the user presses the button then it changes the image and if it re-presses the button then I want the original image back. Is that possible? Is there an easier way using another type of button? Thank you 回答1: Try changing the topic to :"What kind of Button can toggle/change states?" Seems like you need ToggleBotton <ToggleButton android:layout_width="wrap_content"

问题 I'm learning WPF at the moment. I have a vector graphics canvas that I'd like to use as the background for a button, but I can't seem to find a way to do this in the documentation. I thought this would be an obvious thing to want to do. Regards, Mark 回答1: You can use a VisualBrush : <Button Content="Hello"> <Button.Background> <VisualBrush> <VisualBrush.Visual> <!-- Your vector graphics here --> </VisualBrush.Visual> </VisualBrush> </Button.Background> </Button> 回答2: Apologies, I think I've
