Here are the steps,

Step 1: Create MDI forms in Windows Forms Application as in the following figure 1,

Create MDI forms
Figure 1

Step 2: Make some designs using two menustrips as in the following figure 2,

Figure 2

Step 3: Make a new folder named language, then add two resource files, open one resource file and add corresponding Arabic word instead English menu items as in the following figure 3.

resource files
Figure 3

Step 4: Open resource 2 file, add corresponding English word instead menus strip as in the following figure 4.

Step 5: Create table on SQL server then update code status to whether English or Arabic and add this code.

  100. menuStrip.Dock = DockStyle.Left;
  101. }
  102. }
  103. }
The output will be as in the following figure 5,

Step 6: We can design child form for sample Arabic conversion by adding new form, add some labels and controls as in the following figure 6,

  56. // for (int i = 0; i < actTable.Rows.Count; i++)
  57. // {
  58. // activation_status = actTable.Rows[i]["status"].ToString().Trim();
  59. // }
  60. //}
  61. ResourceManager res_man;
  62. CultureInfo cul;
  63. public void langugechange()
  64. {
  65. //checkactivation();
  66. if (activation_status == "Arabic")
  67. {
  68. switch_language()
  69. }
  70. else if (activation_status == "English")
  71. {
  73. }
  75. }
  77. private void Form1_Load(object sender, EventArgs e)
  78. {
  79. langugechange();
  80. }
  81. }
  82. }
The output will be as in the following figure 7. You can change language activation status in SQL server (now I am giving it directly).

Summary

In this article, we discussed how to convert English language to Arabic language in Windows Form C#. After that, we discussed how to use its various properties and methods to build real middle east world application.
