Using WPF to implement multiple customer service functions of WeChat public accounts

Original title: Using WPF to implement the multi-customer service function of WeChat public accounts

Introduction:

This is to use WPF as the front-end technology to achieve Desktop version of WeChat multi-customer service system. The project uses Prism as the front-end framework, uses the MVVM model to perfectly separate the UI and logic code, and uses the MEF IOC container integrated with MefBootstrapper to decouple each module object. Reasonable use of IEventAggregator to implement events and interactions. The article will give relevant implementation references when introducing the corresponding functions. Readers can refer to improvements and introduce them into their own projects.

Program running interface and function preview:

1. Login:

Function: Supports remembering users and user settings, and can choose to remember user passwords.

Implementation related:

Customize the login window and introduce Microsoft.Windows.Shell. You can refer to WPF Custom Chrome Library and MSDN WindowChrome Class for related custom window implementations.

To implement the minimize, maximize, and close button functions, please refer to the above example.

Login button, customize Style, rewrite Button's Template, the reference code is as follows:

 <Style x:Key="LogginButton" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid  >
                        <Border   x:Name="Bd" Background="{TemplateBinding Background }" BorderBrush="#d3d3d3" BorderThickness="1">
                        </Border>
                        <ContentPresenter  x:Name="contentPresenter" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/>
                    </Grid>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter TargetName="Bd" Property="BorderBrush" Value="#08bd14"/>
                            <Setter TargetName="Bd" Property="Opacity" Value="0.8"/>
                        </Trigger>
                        <Trigger Property="IsPressed" Value="True">
                            <Setter TargetName="Bd" Property="Background" Value="#f3f3f3"/>
                            <Setter TargetName="contentPresenter" Property="Margin" Value="2,2,0,0"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Remember the password, use XmlSerializer to serialize user information into the local xml configuration file, and load the file when the program starts xml configuration file. Usage MSDN , Quick reply

RichTextBox related implementation: all input of text, expressions, and pictures are implemented in the rich text box, so the input is processed for the TextChanged event Perform a series of treatments.

Text: No need to do any processing.

Emoticon: Enter the escape symbol of the emoticon in the text box, and then find the corresponding emoticon picture according to the escape symbol and replace it. InlineUIContainer

Gif dynamic graphics: Gif is not supported in WPF, so you need to write a custom user control to display gif expressions.

The control is TabControl, which rewrites the Style of TabControl and the Style of TabItem
