In the program, you need to use progress bars to intuitively reflect the progress of command execution. However, Asp.net does not have any special progress bar controls. I searched the internet and found that the implementation methods are complicated, I just made one by myself, which is actually very easy to implement. Later I thought about a method, which is added later.


Solution 1: Applicable to webform

Results:Figure:

The two-layer div is used to represent the total outer frame of the progress bar and the current progress. By continuously adjusting the DIV width of "processbar", the current progress is displayed.

Background code


Use clientscript. registerstartupscript registers a new JS script to the front-end code, but you need to pay attention to clientscript. registerstartupscript (clientscript. if the key in GetType (), key, STR) is the same, the expression only takes effect for the first time. To continuously refresh the progress bar on the page, we must constantly change the key value.


 Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click        Dim i As Int16        Dim str As String = ""        For i = 0 To 100            str = "<script>"            str += "set();"            str = str + "</script>"            ClientScript.RegisterStartupScript(ClientScript.GetType(), "set" & i, str)                  Next    End Sub


Solution 2: UI code separation


Idea: implemented through intermediate files. Three files are required: front-end files,


Idea: the background program writes the running real-time status to the session. The intermediate file outputs the status of the current session. The foreground file reads the output of the intermediate file repeatedly, obtain the execution progress of the background program and display it to display the progress. This scheme will cause callback execution errors when jquery nested calls are used, and the specific code will be added later.
