How to secure your dynamic objects

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.
  C#

  Copy

  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.
  C#

  Copy

  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

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

• 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

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"

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

You can call a method via a dynamic action.

Example:

• #this.MyMethod()
• #this.MyObject.MyMethod()

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