🔧 Understanding Uniface's endtry Command: Exception Handling Made Easy

Hey developers! 👋 Today I want to share something useful about exception handling in Uniface - specifically the endtry command that closes our try...endtry blocks.

🎯 What is endtry?

The endtry command in Uniface 10.4 defines the end of a try...endtry block used to handle exceptions. Think of it as the closing bracket that wraps up your exception handling logic! 🎁

📋 Basic Syntax Structure

Here's how a complete try...endtry block looks in Uniface:

try
    <ProcScript that may throw an exception>
{catch} {ErrorNumber1 {, ErrorNumberN}}
    <Procscript that handles the error >}
{rethrow}
{finally}
     <ProcScript that will always execute, regardless of whether an error occurred or not>
endtry

🔍 Key Features

• 🌐 Universal Usage: Allowed in all component types
• 🎯 Multiple Catch Blocks: You can have multiple catch statements for specific errors
• 🔄 Rethrow Support: Optional rethrow statement for error propagation
• ✅ Finally Block: Code that always executes, regardless of exceptions
• 🏁 Mandatory Closing: The endtry command must always come at the end

💡 Best Practices

When working with try...endtry blocks in Uniface:

• Always close your try blocks with endtry ✅
• Use specific error numbers in catch blocks for better error handling 🎯
• Leverage the finally block for cleanup operations 🧹
• Consider using rethrow when you need to propagate exceptions up the call stack 🔄

🚀 Conclusion

The endtry command is essential for proper exception handling in Uniface applications. It ensures your try...endtry blocks are properly closed and your exception handling logic is well-structured.

Happy coding! 💻✨
