This paper gives an example of the application of the progress bar when .net is imported into Excel, which is shared with you for your reference. The specific implementation methods are as follows:

In the process of program development, it often involves the requirement of importing the Excel table into the database, but when the excel table contains a lot of content, it is often difficult for us to capture the progress of its execution process and some error messages. At this time, we can solve these problems by the following methods. The specific implementation process is analyzed as follows:

/ / start processing

Function BeginTrans (msg) {

WriteText (msg)

}

/ / set progress bar progress

Function SetPorgressBar (msg, pos) {

ProgressBar.style.width = pos + "%"

WriteText (msg + "completed" + pos + "%")

}

/ / end of processing

Function EndTrans (msg) {

If (msg = "")

WriteText ("done.")

Else

WriteText (msg)

}

/ / set time information

Function SetTimeInfo (msg) {

WriteText (msg)

}

/ / Update text display information

Function WriteText (str) {

Var strTag =''+ str +''

Document.getElementById ("Msg2") [xss_clean] = strTag

}

The copy code is as follows:

/ / 1. For simplicity here, I only write the body part of the front page for reference:
