按钮和键盘按下 [英] Buttons and keyboard presses

问题描述

我正在尝试编写一个简单的表单，用作键盘，按键1到9和零。

我想让按钮在任何当前选中的文本框中输入数字。



例如



如果我有5个不同的文本框，我的光标正在选择我想要的第四个单击bumber 5的按钮并将该号码放入所选的文本框中



任何人都可以帮我一些简单的示例代码吗？



我正在使用Visual Studio 2010并以windows形式开发



我在这方面非常新，所以越简单就越好。



谢谢

I am trying to write a simple form that serves as a keypad which has buttons 1 to 9 and zero.
I want to make the button enter the number into any currently selected text box.

For example

If I have 5 different text boxes and my cursor is selecting the forth one I want to click the button for bumber 5 and get that number put in the selected textbox

Can anyone help me with some simple sample code?

I am working Visual Studio 2010 and developing in windows form

I am very new at this so the simpler the better.

Thank you

推荐答案

按照以下步骤：

1）设计表格将有9个键像num pad

2）on button按下每个按钮的事件就在代码下面

Follow below step :
1) Design form which will have 9 keys like num pad
2) on Button click event of each button right below code

SendKeys.Send("A") // Note : Replace "A" with respective button value

假设单击事件1按钮写下面的代码

Suppose on click event of "1" button write below code

SendKeys.Send("1") // Note : Replace "A" with respective button value
