This is the Delphi code I'm trying to convert to .net:
s1 := Copy ( s1 , 1,x - 1) + Copy(s1, x + 1,Length(s1));
I tried:
s1 = s1.Substring(x - 1, 1) + s1.Substring(s1.Length, x + 1)
But I get error's when the index is out of range. in Delphi it works fine.
Added one line to convert..
s2 := s2 + chr(3);

View 3 RepliesI'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.

From my understanding they are something like structures or arrays in VB, would this be right?
If I am reading the code right than this:

Would something like what I have below work? It seems a bit messy, there must be a better way to do it:

Just wanted to know if you had some design code which was created, and that is all you have. Can you open this designer code and create the actual working main Form from this? I don't need this designer code for any specific task, just wanted to know if there is a command within VB Studio 2010 that creates the actual Form from the design code. For example; The following piece of designer code is for a simple program that finds the Circumference of a Circle.

View 6 Replieshow to use a webcam to take a photo on a Windows Forms application,Now what I need, is to identify which device I'm using to take the photo, in case I ever happen to have two or more similar devices connected to the machine.Currently our setup involves an Asus EEE PC deployed at our location. The machine has an in-built webcam which we are using in the application as described above.Somewhere within this code below, the default device is being identified and selected for taking the pictures we need.
Imports System.Runtime.InteropServices
Public Class Form1
Const WM_CAP As Short = &H400S
[code]....
Now what I need is to find the code that does this identification, and then hardcode the device identity into that code so that if I ever attach another (USB) webcam to the machine in future, it does not inadvertently take a photo from the wrong webcam.

View 3 RepliesI am trying to make a simple log parser that pulls info from a constant (real time updating) log file.it is CONSTANTLY being updated, and i'm having issues. [code] Basically, its messing up when its time to rescan it. I can't use the 'New' on it, as it throws a error on the stream reader.And if it's throwing an error with that, i'd be curious what other errors it will throw.The file doesnt necessarily HAVE to be deleted, but it DOES have to be cleared out. (so the program doesnt have to reparse all the lines).

I have a VB2010 project where I need to read a tab delimited 50MB file using Microsoft.VisualBasic.FileIO.TextFieldParser. This technique works fine until the reader encounters a Unicode character upon which it inserts the little square thingy. The obvious choice is to change the encoding of the reader to Unicode from the default. This would probably work fine but for most files but this one is fairly large and I get the error TextFieldParser is unable to complete the read operation because maximum buffer size has been exceeded. By the way this file can be read completely without the Unicode option. Making the file smaller or breaking it up really isn't an option. Is is possible to increase the buffer size or is there another way to read this data that places the data in fields like the textparser and allows unicode characters?
