防止文本框中的光标闪烁 [英] Prevent Blinking Cursor in Textbox

问题描述

在文本框中，如何防止单击时显示闪烁的光标？

In a textbox, how can u prevent the display of the blinking cursor when you click on it?

我确实在一些论坛中读到有一个调用特定的api，但是当我在代码中尝试使用api时，显示错误。请提供为此目的的完整代码，并让我知道是否在某个特定事件中应执行该代码。

I did read in some forums that there is call to a particular api but when i tried it in my code, an error was shown. Please provide the complete code for this purpose if possible and let me know if there is a particular event where the code should be executed.

此文本框是表单窗口的一部分是为模拟局域网通讯程序而创建的。我正在使用C＃。表单具有两个文本框，以类似于google talk的文本框。希望防止在上方的文本框中显示闪烁的光标。

This textbox is part of a form window that am creating for the simulation of a lan messenger. I am using C#. The form has two textboxes in order to resemble that of google talk. It would be desirable to prevent displaying the blinking cursor on the upper textbox.

我尝试过：

[DllImport("user32")] 
private static extern bool HideCaret(IntPtr hWnd); 
public void HideCaret() { HideCaret(TextBox1.Handle); } 

我收到错误消息：找不到DllImport。

I get the error: "DllImport could not be found."

推荐答案

如果要禁止在文本框中进行编辑，请将其ReadOnly属性设置为true。

If you want to disallow editing on the textbox, set it's ReadOnly property to true.

如果要允许编辑但仍隐藏插入记号，请完全按指定的方式调用Win32 API ：

If you want to allow editing but still hide the caret, call the Win32 API exactly as specified:

[System.Runtime.InteropServices.DllImport("user32.dll")]
static extern bool HideCaret(IntPtr hWnd);

...

HideCaret(myTextBox.Handle);
