虚拟键盘(表格上的A-Z按钮) [英] virtual keypad (A-Z buttons on the form)

问题描述

我正在使用vb.net 2.0设计用于平板电脑的Windows应用程序.
在我所有的表单上，我都希望表单本身具有A-Z和0-9键.
按下这些键中的任何一个，用户都可以在有光标的任何地方键入内容.
问题是如果我按下按钮，焦点将移至该按钮，从而使光标从输入控件中丢失.
谁能告诉我如何使我的按钮没有焦点，以使光标停留在输入控件上?
另外，如果还有其他方法可以使用.
我不应该使用虚拟键盘.

问候，

i am designing a windows application for tablet pc using vb.net 2.0.
On all my forms i want A-Z and 0-9 keys on the form itself.
On press of any of these keys user would be able to type anywhere where there is a cursor.
The problem is if i press the button the focus shifts to the button and thus losing the cursor from the input control.
Can anybody tell how can I make my buttons focusless so that the cursor remains on the input control?
Also if there is any other approach i can use.
I am not supposed to use the virtual keyboard.

regards,
gopal

推荐答案

我多次回答类似的问题，请参见:

应用程序焦点的得失 [在BACKSPACE按钮上编程 [

I answered similar questions several times, please see this:

Application focus getting and losing[^]
Programming on BACKSPACE button[^]

Sorry, the first Question is in C#, but if you want to get good help and code sample and you do .NET development without some understanding of C# you won''t get much help anyway.

这是文章触摸屏键盘UserControl [ ^ ]

还有另一种选择:
如何显示，关闭，移动或调整屏幕键盘大小 [平板电脑 a> [^ ]

WM_SETFOCUS [

Here is an article Touchscreen Keyboard UserControl[^]

There is also another alternative:
How to show, close, move or resize the On-Screen Keyboard[^] - if you are using a tablet, this shows how to interact with the windows wirtual keyboard ...

For more info on what''s available with windows take a look at Tablet PC[^]

WM_SETFOCUS[^] - wParam contains the handle of the previous focused window.

供您控制.由于 Control.GotFocus事件 [ ^ ]确实不包括先前聚焦的窗口的句柄.

for your control. This may be required since Control.GotFocus Event[^] does not include the handle to the previously focused window.

非常感谢您对我们的支持...
我的应用程序现已上线....
但是解决我的问题的方法很简单...

我使用按钮而不是按钮，并在单击该标签时使用了sendkeys.
