Hey fellow developers! 👋 Today I want to share something useful about Uniface development that might save you some time when working with message handling. This post was created with the help of AI and is based on the official Uniface Documentation 10.4.

💡 What is clrmess?

The clrmess statement in Uniface is a simple but powerful tool that clears all text from the message frame and message line. It's one of those small utilities that can make your application's user experience much cleaner! ✨

🔧 Technical Details

Return Values

None - this statement doesn't return anything, it just does its job silently.

Usage Context

✅ Allowed in all component types - which makes it super flexible!

📝 How It Works

The clrmess statement is pretty straightforward. When executed, it immediately clears any text that's currently displayed in:

• The message frame 📋
• The message line 📏

It's worth noting that other statements like store and erase also clear the message frame, so you have multiple options depending on your needs! 🎯

⚠️ Important Note for Debugger Users

If you're working in the Uniface Debugger, keep in mind that clrmess is disabled by default. This is probably to prevent accidentally clearing important debug messages during development sessions.

🚀 Practical Example

Here's a real-world example of how you might use clrmess in your operations:

operation exec
 clrmess
 putmess "Form %%$formname loaded at %%$time."
 edit
end; exec

In this example:

1. First, we clear any existing messages with clrmess 🧹
2. Then we display a fresh message showing the form name and load time 📊
3. Finally, we enter edit mode ✏️

🎯 When to Use clrmess

Consider using clrmess when you:

• Want to ensure a clean slate before displaying new messages 🆕
• Need to clear outdated or irrelevant messages from the UI 🗑️
• Want to improve the user experience by removing clutter 🧼
• Are transitioning between different application states 🔄
