Throw On Unsupported Members property is set to True). NET doesn’t support the Auto Redraw property, therefore implementing double-buffered graphics requires manual code edits.VB Migration Partner supports and replicates the exact behavior of the Auto Redraw property, thus you can easily convert VB6 applications that use double-buffering techniques and persistent graphic output. NET control exposes the Caption property, which has been converted to the Text property.This explicit conversion is necessary, for example, if your application reads color values from a data file or a database, or if you dynamically calculate a color value by means of a method (e.g. You can perform such conversions by means of the To Ole, From Ole, and From Win32 methods of the System. Color Translator type: For uniformity and readability’s sake, VB Migration Partner generates calls to From Ole Color6 and To Ole Color6 methods, which in turn invoke the methods of the Color Translator type.Strings equal to Nothing are converted to empty strings before being assigned to the Text property, thus avoiding unexpected runtime exceptions. Controls in VB Migration Partner’s support library expose this property, but it always returns False; attempts to assign a different value are ignored (or throw an exception if the VB6Config. VB6 assigns and manipulates color values and properties – such as Fore Color and Back Color - by means of 32-bit integers; VB. NET Framework languages represent color values by means of instances of the System. NET, therefore you don’t need any specific fix to have the code compile correctly.
This section describes the differences between VB6 and .NET controls and the problems you can find in migrating VB6 applications with user-interface. supports all the Visual Basic 6 features mentioned in this page.Let's create a label by dragging a Button control from the Toolbox ad dropping it on the form. The following are some of the commonly used properties of the Button control: Public Class Form1 Private Sub Form1_Load(sender As Object, e As Event Args) Handles My Base.
(As in VB6, no Paint event is raised when Auto Redraw is True.) When you drop a VB6 Label control on a form, the initial value of its Back Color property is set to Button Face; when you drop a VB. Notice that assigning the Text property a string equal to Nothing causes a runtime exception.
NET Label control on a form, the initial value of its Back Color property is equal to the background color of the container control. VB Migration Partner support the Caption property, to ensure that converted code works as intended even if the control is accessed via late binding. In most circumstances both the source and the destination of a color assignment become Color values after the migration to VB.
