VBA download file macro

In some cases you will need to download large files (not text/HTML) and will want to be able to control the process of downloading the data e.g. might want to interrupt the process, enable the user to interact with Excel (DoEvent) etc. In these cases the above procedure won’t do. The procedure below may however prove more efficient as it will download the file in 128 byte chunks of data instead of a single stream.

See effect below when executing macro:

How it works

The procedure will download the binary file in 128 byte chunks while saving the contents to the data stream and flushing it into the file once completed. In between the chunks you can call “DoEvents” to enable user interaction, inform the user of the download progress Application.StatusBar or do other thing including interrupting the process and closing the connection. In case you want to do a proper Progress Bar and inform the user of the % progress you may want to leverage this solution.

Bought 2016 and down loaded to new computer Lenovo Idea pad 310 64 bit

Windows 10

Yes able to create and save and alter Excel programs

Just that all .XLS files are keyed in setting to open with Explorer and no way to change app to excel 2016

as the protocol to open , app store had a few to choose but more viewing not doing. I need the .XLS to be linked to

Excel 2016.

I am able to right click on .xls files and 'Open With' - search for Excel 2016 , click on and use it that way. I cannot

set it as a default to open all the time.

I tried some links and searches posted earlier to no avail.

Any suggestions ?

Thanks for the information, Chris.

You mentioned that you have performed steps from previous links and post. Just to confirm, were you able to check the properties of the .xls files to see if there is a tick box to Unblock the files?
