推荐答案

不容易......



1st您需要在提供TouchKeyboard的表单上创建一个方法。此方法必须查看您的任何文本框是否获得了焦点。也许它看起来你是否需要对TouchKeyboard有一个特殊的限制（例如只有数字输入）。

第二，你创建你的TouchKeyboard - 例如作为对话框。此对话框包含应使用的所有不同字符的所有按钮。每个按钮都会修改对话框的Text-Property（您需要并且不应该使用SendKeys）。如果您的输入已完成，您的Text-Property将保留最终输入。

3rd您的Form-method打开Dialog，因为它知道Dialog请求的Control，它也可以将Dialog匹配到调用Control 。当你的Dialog完成后，你只需要将它的Text-Property-Content写入调用控件。

Not an easy going ...

1st you need to create a Method on the Form which provides the TouchKeyboard. This Method has to look if any of your Textboxes got the Focus. Perhaps it looks also if you need a special restriction to the TouchKeyboard (for example only numeric inputs).
2nd you create your TouchKeyboard - for example as a Dialog. This Dialog holds all the Buttons for the different needed characters which should be used. Each of this Buttons modifies the Text-Property of your Dialog (you need and you should not use SendKeys). If your input is finished your Text-Property holds the final Input.
3rd your Form-method opens the Dialog and because it knows which Control the Dialog requested it could also position the Dialog matching to the calling Control. When your Dialog has finished you only need to write it''s Text-Property-Content to the calling Control.
