C # Use code to open the keyboard

I studied APIs some time ago, but I didn't play C # any more because of my work. I work overtime this evening, and wait for other departments to wait until a little more early in the morning. I just took the opportunity to play a game, just to learn about vs2005.
I used to see how to use csdn.ProgramWhen I opened the soft keyboard, I also paid attention to it, but there was no result. I searched the internet and couldn't find a satisfactory answer. Today, let's get started with this. There is no anti-zhengda project, just a small function. I did not think about the result. I haven't updated my three-point field for a long time.

To those who are making efforts to share software in China and improve the program level in China.

Note: The program is in vs2005. Pay attention to it. Control needs to be added by yourself. A ComboBox, A Textbox, and a button are dragged in directly without changing the name.

====================================
CodeEnd.
In addition, you can directly execute osk and directly open the virtual keyboard, but this is different from the soft keyboard.
Now, more anti-phishing software is available, and I wish you all the same progress.

Thank you for your support. I sent it last night. Now several people have asked me about it. For your convenience, I have also sent the source program to the attachment, for your download reference.
