How do I restrict the upload filesize

[OMER AHMED]

Hi

i am making an application in vb.net and i need help. The user will send me his issues or information through attachment. but i want a restriction on filesize that he can not attach file more then 20MB

i did some coding but its not working. it will show the size of file but not axectly the size in MB..

dim filesize=my.computer.filesystem.getfileinfo(textbox1.text)
msgbox filesize.length

now in above code it will show me the size of file in textbox1 but in bit like 1234567

i need it to show me in MB like 1MB or 10KB

Thanks

Old post, probably not the only one but here is one i answered years ago. Example is C# but I'm sure you will figure it out ;)

You need to apply some division to the file.length as this comes in bytes based on the charcters in your file. Here are some of the divisions:
info.Length / 1024 '= kilobytes
info.Length / 1048576 ' =megabytes
info.Length / 1073741824 '= gigabytes

Well, the deliminator depends on the region for which your computer's system or program is set.
To only display the required digits use the math.round function:
Math.Round(value, 1)
