Description:
BackgroundWorkAction: Load Resources Task function
CurrentMsg: current progress message display, key: task progress, values 0-100 value: the name of the current task
BindingProcessMsg: Binding data to the interface, subclasses need to override this function to achieve the binding data to a display screen
Example:
Add a form FrmTestLoading inherited FrmLoading
Add a text label1 text displays progress information
Add a progress bar shows the progress of the value ucProcessLineExt1
Re BindingProcessMsg binding information
1 protected override void BindingProcessMsg(string strText, int intValue) 2 { 3 label1.Text = strText; 4 this.ucProcessLineExt1.Value = intValue; 5 }
