问题 I have been looking around for a while for some code that tells what control the mouse has clicked. I have a Form with over 50 controls and I don't want to click each one to make a mouse clicked on. How would I do this? 回答1: You can use the Tag property of each control. So set it to something meaningful and on Click event do something like this: (sender As Control).Tag EDIT: Also you may do this: foreach (Control item in this.Controls) //this IS YOUR CURRENT FORM { if ((sender as Control)

问题 I'm building a WPF application with some hackery involved to embed Form elements on the same render layer. Essentially what I do is I render the form off-screen and have a mock-up of the form in a WPF image. I also have a low level mouse hook which steals events from the WPF application if they are destined for the Form mock-up and instead use PostMessage(...) to send the events off to the hidden form element. If I return a non-zero value from my hook procedure indicating to eat the event

问题 I am trying create a search word puzzle box with JQuery. Basically a table with an alphabet in each cell and the user needs to find and mark the words in the grid by clicking the table cells. So I am trying to combine the clicks and hover events the following way: All cells should have a hover highlight effect when the mouse is over except when it was already clicked. If it was clicked then it should just change to a different color to mark active selection so the hover effect is removed.

问题 I wanted to create a button that had an image and a textblock as content. So I went about looking for an answer and found a post ( Reusable Custom Content for Buttons ) which told me to create a usercontrol. I did this and it works great. I can set the image source and text through dependency properties. However, I am stuck as there is no click event for my control. I did a little more digging and concluded that I probably need a CustomControl derived from Button. Is this correct? Or would it
