I  am sorry for my bad express.I just want to finish the following process:

1、browse the file,what is called fw.bin;

2、submit the form using the update button.

you need to upload your html file so that we can better uderstand.

Most likely your device expects a HTTP Post (or maybe HTTP Put) command with the binary file as contents. You can create a HTTP Post transaction with the HTTP Client library in LabVIEW.

What you need to find out is the url that the device expects for the upload. That can be retrieved from the HTML file that you see in your browser by looking what url and command is used to post the file when you click your upload button.

A more automated way would first use a HTTP Get to retrieve your firmware update page on the device, then parse the returned HTML string for the relevant url and command and then issue the HTTP Put or HTTP Post with your firmware file.
