VS 2008 Error "The Requested Performance Counter Is Not A Custom Counter"
May 20, 2010I have this code sample from a book I'm reading which looks to be incorrect:
Imports System.Diagnostics
Sub Main
Dim pc As New PerformanceCounter("PerfApp", "Clicks", False) 'excepiton here
pc.Increment()
counterLabel.Content = pc.NextValue().ToString()
End Sub
There excepion message I get is: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly. I looked for a property to see if I can set it but couldn't find one.
Asp.net - How To Manage An IF Statement
Nov 17, 2011I have a total of 102 values associated with a fieldname called ArrivedFlag.Then I have a TextBox control with an id of txtFlag on the markup page.In my codebehind, I have an if statement that says:
If txtFlag <> "value1" and txtFlag <> "another value" Then
lblMessage.Text ="You don't have the ability to view details"
end if
This works fine.However, given that there are 102 values, I feel that doing an IF statement 102 times is a bit inefficient.
Dim allowedFlags = New List(Of String)()
With { _
"value1", _
"another value"

Best Way To Manage GUI States
Dec 11, 2011I was asked by a client to create a tool that would let a user add/modify/delete/read content from a database. The content can be read from TextBoxes.
My question is, what is the best way to manage GUI locks/unlocks for the different states of the program. IE: If I'm in a "insert" mode, some GUI elements should be enabled, and some not. If I'm in the "read-only" mode, a bunch of them should be disabled... etc.
Best Way To Manage Strings?
Aug 21, 2010I am writing a program that uses an array with three columns and a varying amount of rows. I need to load info on a list of files in an archive(specifically: file name, size, path), and I am wondering what the most convenient way to store strings(to be loaded into the array) is.
For example: I tried creating a new .resx file in my project, and writing a function to be executed on form1_load that reads the strings from the .resx file and places them in the array in their correct column, but unfortunately had no success.
I really have no idea how resx files work, I can put strings in them using the resource editor, but I don't know how to retrieve them using resourcemanager.
I would just put the info straight into an array, but it's much easier to update a .resx file when the archive changes than it is to update the code.
Could someone please tell me how to use .resx files in vb.net? Or an easier way of accomplishing my goal?
Can't Manage To Add Different Values Together
Feb 3, 2011I can't manage to add different values together...
TextBoxAnswer.Text = TextBox1.Text + TextBox2.Text + TextBox3.Text + TextBox4.Text
I import decimal values from my SQL Server into the TextBoxes 1-4, which works fine. But when I try to add the values together into another textbox the answer is just the values combined like a string...?The column of the table in the SQL server has a datatype decimal(18, 2)I have also tried to convert the values in the textboxes into int, str, double... Nothing seems to work...
Example:
Answer = 2,50 + 2,50 + 5,50 + 4,50
So,
TextBoxAnswer.Text = 10,00
but, all I get is:
2,502,505,504,50
How To Manage Directories
May 29, 2012I am now convinced there is no such thing using VB 2010 Express. I have read, re-read, studied, copied and pasted code to no end and all I get are error messages galore. It appears there is a big gap between what's on line as far as tutorials and the code that VB 2010 Express will accept. I hate to sound so lost but at the moment I am. I used to program in BASIC and QBASIC. I was a master at opening up ascii text files, reading them in sequential order, sorting, manipulating, then re-writing them. It was all so easy, like this: [code] That's all I want to learn how to do for the moment. But every tutorial or article I find goes off in to wild tangents about How to Manage Directories or it reads the entire text file into one giant object. Or worse, there's some code which looks promising but it won't run under VB 2010 Express or it might run but the author leaves out important parts of the code that have to be declared ahead of the subroutine....you all know what I mean. It can't be this difficult to just read a text file one line at a time, therefore it shouldn't be so difficult to find an accurate and up to date article on this.This is for really rough programming. I don't need an interface of any kind. The user, will not even need to know that anything is happening. I simply want to read text files, manipulate what's in them and then re-write the edited text.

View 1 RepliesManage GSM Modem Response?
Aug 10, 2011I'm creating a small program in Visual Basic, using Visual Studio 2010, which communicates with a GSM modem via serial port.The connection works, I can even communicate properly with the modem and I can also send sms and mms .. But I can not handle the modem answers ... I'll explain:If I send a command like AT + CSQ modem replies with + CSQ 22.0. This command gives me the value of the signal as a response on a scale of 0-30 ... I can see on the screen (in a dedicated console) but I would like to manage the response in the sense that I would do something like that
IF (answer.text = "+CSQ 22,0") Then
label1.text = "Good"
ELSE
label1.text = "Bad"

Manage Queries In Application?
Jan 6, 2012I have an application that works together with a SQL database. This database has more than 40 tables and my applican has to extract different situations from those tables.
I have predefined some queries for the situations that I know they need to be in the application.
The idea is that I need kind of a module in which an user can create his own situation based on the tables, views, functions and procedures that already exist in the database. Something like it is in SQL. There has to be a library or something which will read my sql database directly from my application and which allow the user to create his own queries and situations.

View 5 RepliesProperly Manage Data From XML?
Nov 3, 2010I am reading data from an XML file. This local XML file will be updated by another application, and I will need to periodically re-evaluate the XML file, and only import new data into a list box. Furthermore, I want to be able to click on a particular item in the listbox, and display the other values about that particular XML entry.
So, I suppose this is a multi part question. What is the proper way to import only NEW data into the program, what is the proper way to store the data, and how do I associate a value in a listbox with the data stored elsewhere?
I've considered multidimensional arrays, but have been told that strings to char arrays and then back to strings is a terrible way to manage the data, but was never offered an alternative.
VS 2010 How To Manage Several Forms
Nov 17, 2011The first thing that I have found difficult to manage is when a program has several forms. Basically what I do is just hiding one and showing up the other form. it does not look that nice. I was thinking of having one form and laying all the other forms on that one. Let me explain myself more thoroughly. Let's say to the left hand side of my form, i have few group boxes with buttons. So when clicking a button, it should automatically close the form and show up the new one on the main form. Its like refreshing the form. So what I mean is that there is only one main form and clicking each button will show another form.
