This application too, has a form-building error.Debug Error Message: An error occurred creating the form. See Exception.InnerException for details.

How can I download a file from my website, put it in the Application.StartUpPath, Delete the old file, and then run the new one that I just downloaded?
Also, the old file and the new file should have the same name (demo.bat), so will windows automatically replace the old one with the new one, or will I have to program it to do that?
vb.net
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("http://halfbot.webs.com/hBot%20Update/EliteVersion.txt")

So I want to now if that possible for .NET languages to ignore error without using try catch construction ?
I can ignore warring with #nowarring 40 for example, can I ignore error ?
simply wanted to call system pause with this way
open System.Runtime.InteropServices
[<DllImport(@"msvcrt.dll")>]
extern void system(string str)
system "pause"
but got Error message
unbalanced stack. This is probably because the managed PInvoke signature does not match the unmanaged target signature. Make sure that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
So I don't care, it works. But can I just ignore this error ? without doing weird stuff like that :
try (system "pause") catch |_->()
Ok , I solved my problem by adding CallingConvention=CallingConvention.Cdecl, but what the question was about skipping exceptions, so and I still don't know if I can do it.
So maybe I need to tell some real reason to not be down-voted hard - sometimes it's matters for program to live even with hard errors occupations, but even sometimes you don't need to catch them. You need just ignore them...
I'd like to make the form load, and then download a file from a URL to a designated path, and then make it's Progress to affect the Progress Bar. How do I do that?

View 3 RepliesIn my form I have a variable that is of the type Windows.Forms.Form. When my program is enabled/disabled I create a new form instance in there and close it (respectively). Since I don't want the form sitting in memory the whole time my program is open the references to properties of the form are invalid (because the initial declaration is not the form but the type). How can I either negate this or ignore this error?
