foreword
I can abstract the whole world, but I cannot abstract you. Wants to make you a private constant so outside functions can't access you. I also want you to be a global constant so that I can call you throughout my lifetime. It's a pity that there is no such constant in the world, and I can't define you, because you are so specific in my heart.
Hello everyone, this column is the [Project Actual Combat] column, which is different from the [Underlying Library] column. We can find that the chapters "Problem Description" and "Project Display" have been added, which is very in line with the project development process and allows readers to understand the project more clearly. The problem to be solved, and the effect that the product can achieve. This column contains solutions to the project development process, which is the refinement of relatively mature and reliable methods for my project development. I will sort out the solutions to these problems and write this article to share with you. If you encounter similar problems, you can deal with them according to the solution in this article.
This column will continue to be updated and improved, and the column articles are weakly related (the dependencies between articles are weak, and there is no reading order). If you have any questions, you can private message me. If you are interested in this column, please pay attention. I will show you how to use the most concise code to realize complex functions.
·提示：本专栏为项目实战篇，未接触项目开发的同学可能理解困难，不推荐阅读。
1. Problem description
[C#] Set the input method to solve the problem of abnormal recognition of the scanner in the Chinese state
Two, the solution
When the text input box is focused, switch the input method to English. This can ensure the correctness of the barcode scanner recognition.
3. Software development (source code)
3.1 Set the system input method
//函数内容: 函数方法，设置系统输入法
//函数版本: 0.0.0.0
//修改时间: 2023.07.12
//修改人：gyc
//============================================================================================
//注意事项：
//1.语言项，如zh-CN，en-US
//2.
//============================================================================================
private void InitializeInputLanguage(string cultureType)
{
//获取系统中已经安装的文字输入法
InputLanguageCollection MyInputs = InputLanguage.InstalledInputLanguages;
//遍历获取英文输入法索引值
for (int i = 0; i < MyInputs.Count; i++)
{
if (MyInputs[i].Culture.IetfLanguageTag == cultureType)
{
//获取英文输入法
InputLanguage enInput = InputLanguage.InstalledInputLanguages[i];
//设置为当前输入法
InputLanguage.CurrentInputLanguage = enInput;
break;
}
}
}
3.2 Text input box Enter event
The text input box gets the focus, use
Enter()orGotFocus()event, it is recommended to useEnter().
Binding event:
this.baseDataInput_ReadLabel.Enter += new System.EventHandler(this.baseDataInput_ReadLabel_Enter);
Call method:
private void baseDataInput_ReadLabel_Enter(object sender, EventArgs e)
{
this.baseDataInput_ReadLabel.ImeMode = System.Windows.Forms.ImeMode.Disable;
InitializeInputLanguage("en-US");
}
3.3 Add English input method
On some computers, the English input method is not installed, and it needs to be installed, otherwise the program will not see the effect.
Operation steps: All Settings –> Language –> Add Preferred Language –> English.
