C#: Calling a WLanguage procedure
A global procedure in WLanguage can be directly called from the code of a global procedure in C#. To call a WLanguage procedure from the code of a global procedure in C#: - Type the code of the WLanguage procedure. The WLanguage procedure must comply with some rules:
- Have an acceptable name in C#.
- The parameters of the WLanguage procedure and the return value must be of a supported type: Boolean, integer, real, string, buffer. It is recommended to pass parameters by value using the "LOCAL" keyword.
- The extension attribute "C#" must be added to the WLanguage procedure.
Example:
PROCEDURE nWL_AddOne(LOCAL n is int), C#: int
RETURN n+1
- Then, you can simply call the procedure from the C# code.
For example:
int nCSharp_ResultInt(int i)
{
return nWL_AddOne(i);
}
Use example for a .Net assembly A global procedure in C# can call assembly functions by using using: For example: - Global procedure displaying a "YesNo" message:
using System.Windows.Forms;
public static bool pTEST(string _sMessage, string _sTitle)
{
DialogResult result;
result = MessageBox.Show (_sMessage, _sTitle, MessageBoxButtons.YesNo,
MessageBoxIcon.Question);
return (result == System.Windows.Forms.DialogResult.Yes);
} - Call to the procedure from WLanguage (click code of a button or other):
bRes = pTEST("This is my message", "My configured title")
Info("YesNo in C# returned" + (bRes? "Yes" ELSE "No"))
