//! # `LoadResString` Function
//!
//! Returns a string from a resource (.res) file.
//!
//! ## Syntax
//!
//! ```vb
//! LoadResString(index)
//! ```
//!
//! ## Parameters
//!
//! - `index` (Required): Integer identifying the string resource
//!   - Must be a numeric ID (string names not supported for string resources)
//!   - Must match the ID used when the resource was compiled
//!   - Typically ranges from 1 to 65535
//!
//! ## Return Value
//!
//! Returns a String:
//! - String containing the text from the resource file
//! - Empty string ("") if resource not found (in some VB versions)
//! - May raise error 32813 if resource not found
//! - Preserves all formatting including line breaks
//! - Unicode strings supported in VB6
//!
//! ## Remarks
//!
//! The `LoadResString` function loads text from embedded resources:
//!
//! - Loads strings from compiled resource (.res) files
//! - Resource file must be linked to project at compile time
//! - Primary method for internationalization (i18n) in VB6
//! - Allows localizing applications without code changes
//! - Strings can be translated by replacing resource file
//! - No external text files needed at runtime
//! - Embedded in compiled EXE/DLL
//! - Only one resource file per project
//! - Resource file added via Project > Add File
//! - Resource files created with Resource Editor or RC.EXE
//! - Index must be numeric (string names not supported)
//! - Common for error messages, prompts, labels
//! - Supports Unicode in VB6
//! - Error 32813: "Resource not found" if ID doesn't exist
//! - Error 48: "Error loading from file" if resource file corrupt
//! - More maintainable than hardcoded strings
//! - Easier to update text without recompiling code
//! - Standard practice for multi-language applications
//! - Can store long text passages
//! - Supports special characters and formatting
//!

//!
//! ### Example 1: Loading Messages
//! ```vb
//! ' Load various UI strings from resources
//! Me.Caption = LoadResString(1001)          ' "My Application"
//! lblTitle.Caption = LoadResString(1002)    ' "Welcome!"
//! cmdOK.Caption = LoadResString(1003)       ' "OK"
//! cmdCancel.Caption = LoadResString(1004)   ' "Cancel"
//! ```
//!
//! ### Example 2: Error Messages
//! ```vb
//! ' Use resource strings for error messages
//! If Not fileExists Then
//!     MsgBox LoadResString(2001), vbCritical  ' "File not found"
//! End If
//!
//! If accessDenied Then
//!     MsgBox LoadResString(2002), vbCritical  ' "Access denied"
//! End If
//! ```
//!
//! ### Example 3: Error Handling
//! ```vb
//! On Error Resume Next
//! Dim msg As String
//! msg = LoadResString(9999)
//! If Err.Number = 32813 Then
//!     msg = "String resource not found!"
//!     Err.Clear
//! End If
//! MsgBox msg
//! ```
//!
//! ### Example 4: Form Initialization
//! ```vb
//! Private Sub Form_Load()
//!     ' Load all UI strings from resources
//!     Me.Caption = LoadResString(1001)
//!     lblName.Caption = LoadResString(1002)
//!     lblAddress.Caption = LoadResString(1003)
//!     cmdSave.Caption = LoadResString(1004)

//!     errAccessDenied = 2

//!     mnuFile.Caption = LoadResString(baseID + 10)
//!     mnuHelp.Caption = LoadResString(baseID + 11)
//! End Sub
//! ```
//!
//! ### Example 4: String Template System
//! ```vb
//! ' Module: StringTemplates
//! Private Const TEMPLATE_BASE = 30000
//!
//! Public Function GetFormattedString(ByVal templateID As Integer, _
//!                                    ParamArray values()) As String

//! End Function
//!
//! Private Function GetMessageCount() As Long
//!     ' Implementation would return actual message count
//!     GetMessageCount = 5
//! End Function
//! ```
//!
//! ## Error Handling
//!
//! ```vb
//! ' Error 32813: Resource not found
//! On Error Resume Next
//! Dim msg As String
//! msg = LoadResString(9999)
//! If Err.Number = 32813 Then
//!     MsgBox "String resource not found!"
//! End If
//!
//! ' Error 48: Error loading from file
//! msg = LoadResString(1001)
//! If Err.Number = 48 Then
//!     MsgBox "Resource file is corrupt or missing!"
//! End If
//!
//! ' Safe loading pattern
//! Function TryLoadResString(ByVal resID As Integer, _
//!                           ByRef outString As String) As Boolean
//!     On Error Resume Next
//!     outString = LoadResString(resID)
//!     TryLoadResString = (Err.Number = 0)
//!     If Err.Number <> 0 Then
//!         outString = ""
//!     End If
//!     Err.Clear
//! End Function
//! ```
//!
//! ## Performance Considerations
//!
//! - **Fast Access**: Strings embedded in EXE (very fast loading)
//! - **No File I/O**: No disk access required
//! - **No Caching**: Each call loads fresh copy (implement caching if needed)
//! - **Memory Efficient**: Strings only loaded when accessed
//! - **Cache Strategy**: For frequently used strings, cache in Collection or array
//! - **Startup Time**: Loading many strings at startup may slow `Form_Load`
//!
//! ## Best Practices
//!
//! 1. **Use constants** for string IDs for maintainability
//! 2. **Group by category** using ID ranges (1000s for errors, 2000s for menus, etc.)
//! 3. **Cache frequently used strings** to improve performance
//! 4. **Always handle errors** - resource might not exist
//! 5. **Document string IDs** in code or separate file
//! 6. **Use templates** with placeholders for dynamic content
//! 7. **Organize by language** using ID offsets (English: 0, Spanish: +1000, etc.)
//! 8. **Test all languages** before deployment
//! 9. **Provide fallbacks** for missing strings
//! 10. **Keep strings updated** in sync with code changes
//!
//! ## Comparison with Related Functions
//!
//! | Function | Purpose | Return Type | Data Type |
//! |----------|---------|-------------|-----------|
//! | **`LoadResString`** | Load string from resources | String | Text strings |
//! | **`LoadResPicture`** | Load image from resources | `StdPicture` | Images |
//! | **`LoadResData`** | Load binary data from resources | Byte array | Binary data |
//! | **`LoadString`** (API) | Windows API alternative | String | Text strings |
//!
//! ## `LoadResString` vs Hardcoded Strings
//!
//! ```vb
//! ' Hardcoded - difficult to localize
//! MsgBox "File not found", vbCritical
//!
//! ' Resource string - easy to localize
//! MsgBox LoadResString(1001), vbCritical
//! ```
//!
//! **Advantages of `LoadResString`:**
//! - Easy localization (just replace .res file)
//! - Centralized string management
//! - No code changes needed for translations
//! - Consistent messaging across application
//!
//! ## String ID Organization
//!
//! ```vb
//! ' Recommended ID ranges
//! Const STR_APP_BASE = 1000         ' Application strings
//! Const STR_ERROR_BASE = 2000       ' Error messages
//! Const STR_MENU_BASE = 3000        ' Menu items
//! Const STR_DIALOG_BASE = 4000      ' Dialog messages
//! Const STR_STATUS_BASE = 5000      ' Status messages
//! Const STR_HELP_BASE = 6000        ' Help text
//!
//! ' Language offsets
//! Const LANG_ENGLISH = 0
//! Const LANG_SPANISH = 10000
//! Const LANG_FRENCH = 20000
//! ```
//!
//! ## Platform Notes
//!
//! - Available in VB6 (not in early VB versions)
//! - Requires resource file (.res) linked to project
//! - Resource file created with Resource Editor or RC.EXE
//! - Only one resource file per project
//! - Resources embedded in compiled EXE/DLL
//! - Supports Unicode strings in VB6
//! - Index must be Integer (1-65535)
//! - String names not supported (numeric IDs only)
//! - Standard method for internationalization
//! - Preserves formatting including line breaks
//!
//! ## Limitations
//!
//! - **One Resource File**: Only one .res file per project
//! - **Numeric IDs Only**: Cannot use string names for string resources
//! - **Compile Time**: Must recompile to update strings
//! - **No Modification**: Cannot modify resources at runtime
//! - **Limited Editor**: VB6 Resource Editor is basic
//! - **ID Range**: Limited to 1-65535
//! - **No Encryption**: Strings easily extractable from EXE
//! - **No Formatting**: No printf-style formatting (must implement manually)
//! - **No Pluralization**: No built-in plural form handling
//! - **No Context**: All strings in flat namespace
//!
