    VS 2019 Re: DownloadFileAsync not so Async

    I'd be very surprised if call(s) to DownLoadFileAsync caused the UI to freeze. I think the problem is much more likely to be found in code you haven't shown, or in the way you are using the code that...
  2. Re: Weird Bug - If System.IO.Directory.Exists("C:\Windows\System32\OpenSSH")

    Assuming you have a 64bit OS, then to access most items in the C:\Windows\System32 folder you need to compile to 64bit.
    32 bit apps will be redirected to look in C:\Windows\SysWOW64 and I don't...

  5. VS 2019 Re: Need to write stringbuilder data as test during debugging.

    StrPadding is an array. It doesn't make sense to append an array to a StringBuilder. What you want to do is make a String from the contents of the array and append that String to the StringBuilder.

  7. VS 2019 Re: Visual Basic Do while loop condition for termination.

    As OptionBase1 says, you should never update TextBoxes or other Form Controls in a loop. For one thing, the GUI is only updated when it is idle; i.e. after the loop exits and your code isn't running...

    VS 2019 Re: is it a Variable or an Array?

    VB on the .NET platform doesn't have dynamic arrays.

    It looks like you are closing the default instance of the form:

  16. Re: BigInteger trying to convert result to Double

    The problem is in the CType.

  26. VS 2010 Re: VB.NET Streaming Image Using Imag2Pipe Issue
