Unable To Read All Keys From A Section Without Knowing Exactly?
Aug 6, 2009
ok so sql lite version of this was easy, why now do i have to make an ini version because boss said so.here it is.I am using a simple ini class to read and write to inis mostly no problem except one thing I need to be able to read all keys from a section without knowing exactly how many there are and grab the every variable from every key.below is class i'm using at moment because it is small and very litl overhead,I dont need a major overhaul, just wondering if anyone might can add to what i have to do what i need.
for futher thought, grab section --> grab every key and it's variable --> use each variable in a loop for instance say i store a bunch of exe paths to a bunch of keys (1-100) and i want to run a loop Process.Start(eachKey'sVariable)

I need to store some information in my Configuration Section. Probably three different sections with each having I want to hand type in the custom configuration section and then read it in my program. Looking for a good example but have not found it yet. I do not want to use appSettings, Key/value pairs. Need something with more depth than that. Also, what are the standard naming conventions for Config or xml file tags? When to start with an uppercase, when to use a ".", etc.

I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.

I am trying to use the vb.net method FileGet to populate a type library from a text file. This text file was created by a legacy application using vb6. In the vb6 code, the Put method was used to create this file by dumping the type library into the file. I'm using the same type library to parse back into using the FileGet method. The only difference is that the type library is now an interop dll. When I use the FileGet, it works for most of the files that I'm trying to read.
However, there are a few that give me the error: "Unable to read beyond the end of the stream." Does anyone know what would cause this error and how I can fix it?I've already tried to add a space and a line break at the end of the file.This did not work. I've searched for the solution but have not found anything that has worked.[code]...

Ok, so I have a 'Form' and a 'Code File'. I am thinking of having the Code File stock full of arrays. And since my arrays are huge, just gonna do an example.
CodeFile1.vb
Dim numbersSpelled() As String = {"One", "Two", "Three", "Four"}
In my 'Form1.vb', I have a combobox I am trying to fill... I've spaced on the code for that. I am just typing away what I hope would work... And, I have totally just forgot the code... oops. Here is just something that looks like it should work, I am so sorry.
Imports BigProgram.CodeFile1
Public Class Form1
Private Sub Form1_Load(...) Handles MyBase.Load
ComboBox1.Array.Add = numbersSpelled()
End Sub
End Class

I am creating a custom config section that will allow me to manage what ELMAH exceptions I want to ignore from my VB.NET/ASP.NET app. Here's my code. I made it easy to paste in a blank code file if anyone's up to the challenge of diagnosing the problem.
CODE:
When I execute this code:
CODE:
I get the error An error occurred creating the configuration section handler for IgnoredExceptionSection: Could not load file or assembly 'WEB' or one of its dependencies..
What boggles my mind is that this all works fine in my C# console test app after I convert the code from VB.NET using a web utility. However, when I paste the VB code from my web app into my VB.NET console test app, it doesn't work there, either, so it appears to be a C#/VB issue. What am I doing wrong here?

I designed a vb.net application. In this application I am using some file which are in WindowsSystem32 folder. Each and everything is working file, but when I install my application on any x64 machine. My application is unable to read the in WindowsSystem32 files. I think this is because of WOW64(windows-32-on-windows-64) issue. I don't want to install these files at any other place because of application security purpose.

I'm gearing up to work on a project which is migrating from VB6 to .NET 4.0. I have Visual Studio 2010 but wanted to try and open the original source code using the VB6 IDE. Can one still acquire this anywhere?I checked here:http:[url].... I have tried opening the original vb project file by changing the suffix from vbp to vbproj (let's call it MyProject.vbproj) but it just says it cannot interpret the file:

I am building a chat client/server. And I can connect and chat just fine, but when a user disconnects, the server does not recognize this and acts weird, often spamming the last message that was sent by the user..Also, it's like the client does not disconnect from the server even when I close the client app. Once I exit the program, VB acts like it is still debugging. Once the server is shut down however, I get this error:
IOException was unhandled:Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
serverStream.Read(inStream, 0, buffSize)I don't know how to make my client and server accept the fact that a client has disconnected...
