Global variables in Windows Form Application.

You can declare global variables in a few different places depending on your requirements:

• Static Class: You can create a static class to hold global variables. This approach is useful if you want to access the variables across multiple forms or classes without having to instantiate an object.

  public static class GlobalVariables
  {
      public static SAPbouiCOM.Application oApplication = null;
      public static SAPbobsCOM.Company oCompany = null;
  }
  
  public class SomeOtherClass
  {
  	public void SomeMethod()
  	{
  		// Accessing global variables from Program class
  		var application = GlobalVariables.oApplication;
  		var company = GlobalVariables.oCompany;
  	}
  }

   

• Application Settings: You can also use application settings to store global variables. This approach is suitable for variables that need to persist between application sessions.
  • Right-click on your project in the Solution Explorer.
  • Select "Properties."
  • Go to the "Settings" tab.
  • Add your global variables as settings.

            Then, you can access these settings using Properties.Settings.Default.VariableName in your code.
