Securise your dynamic objects

Introduction

This class lets you secure your dynamic objects.

 

Dynamic objects are objects that are not visible in the Visual-Guard "Property Action" editor's treeview. In general, these objects are created by writing code and stored in an object list. Because they do not have a direct reference in the object, you cannot select them from the treeview.

Example:

• Winform: If you directly add a "Label" in your "Form" in your Constructor.   (Label lbl = new Label(); lbl.Name = "mylabel"; this.Controls.Add(lbl); )
• Webform: If you directly add a "Label" in your page in the "Page_Load" method. (Label lbl = new Label(); lbl.Name = "mylabel"; this.Controls.Add(lbl); )

By using VGExpression, you can select and modify a "Label" property such as these #this.Controls['mylabel'].Visible = false

Requirements

To use dynamic objects you must have Visual-Guard version 2.8.

Specifications

• · Objects used in VGExpression must have their "Namespace". (For example: New System.Windows.Forms.Label())

• · You can classify the execution order of the "Expressions" by using the "Up" and "Down" buttons

Usage

1. Open a VGRepository

2. Open an application

3. Open a permission

4. Create or edit a "Property Action"

5. Go to "Select the component and edit the properties"

6. Click "Add Expression"

7. Submit your VGExpression

8. Click "Finish"

VGExpression Type

Modifying a property of a dynamic object

To do this your property must have a get function in write mode. Your VGExpression is made up of two parts: The first is the target, the second is the value.

Example:

• #this.MyProperty = myValue

• #this.MyObject.MyProperty = myValue

 

Calling an object method

You can call a method via a dynamic action.

Example:

• #this.MyMethod()

• #this.MyObject.MyMethod()

Restrictions

• "ReadOnly" list: You cannot change a value in a list that is "ReadOnly".
