VS 2010 Creating An Application For Multiple OS?
May 25, 2012
I'm trying to develop an application in VB 2010 that will monitor files in a directory that the user specifies. The problem is, this application is going to be installed in diferent computers with diferent Operative Systems (windows 2000 and XP).Is this possible? or should i change mi programming lenguage?Another thing that comes to my mind is that maybe i should use diferent frameworks (i'm afraid that framework 4.0 may not work in Windows 2000).I apologize if i'm posting in the wrong place, i'm new here.

I have multiple forms and reports with different print area. Some are designed to print to a thermal label printer and others to department shared printers. Currently the user is able to change the printer in print dialog box and print to differernt printers. I want to be able to create a form where the user can assign different printers for different jobs and not have to worry about it.
The problem is, i have never worked with printing function and my collegues arent too smart so I was wondering if someone can throw me ideas on where to start so i can start googling for it.

I'm creating a twitter account manager using the Twitter API. I have multiple accounts, over 10 of them. I want to automate all 10 of these accounts to do certain things, now the way I started to code the program was so that it would accommodate only one account, and all the codes worked perfectly and were managed by individual timers for individual processes that I wanted done. i could tweet between certain intervals, follow people who tweet certain things without me being on top of it.
Now the problem is that I've been trying to create new instances of subs that I've already created so that I dont have to create 10 new subs with the exact same procedures. I'm pretty sure it's impossible to create copies of subs dynamically or within a loop but it didn't stop me from trying. So question is how can I edit a program that was designed to accommodate and automate only one account, to potentially accommodate over a 100? I don't need codes or anything I need ideas so I can try them, but right now I'm completely blank.

I have a form which has a textbox named "textbox1", and a button named "Button 1". Button 1 is meant to be a submission for textbox1 (i.e. when button1 is pressed, the value of textbox1 is saved and remembered). I want the value of textbox1 to be remembered on any computer, but I need it to be update-able too.I tried using settings to do this like so:
Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.TextBox1.Text = My.Settings.TextBox1
End Sub
[code]....
but the problem in doing this is it only works for the current user. When the application is then put on another computer the value is blank.

I am converting an older software package written in VB 6 to VS 2010.Not to incredibly painful but planning for the future as we have had lets say a few issues with VB 6 on our current layout of multiple OS and this is my first real project lead.We are a smaller job shop and we move on a rotation of new PC's/OS's come in to replace broken or exhausted older PC's in the front office and move the older PC's out to the shop floor.We have an array of different OS's ranging from Windows 98 and Windows 7 (32 bit and 64 bit OS). By the time I am done with the conversion we should be sitting comfortable with a range of PC's from XP and up. When creating the executable for my project is this something that can be handled ahead of time, creating multiple executables for specified OS, or an all in one package executable?I was looking to see what people had as suggestions at handling this.We haven't even bought VS yet and are looking at the VS 2010 Premium package, do I need Ultimate?

I need to create multiple splitters, then getting that data and adding it into a DataGridView;
AAL1238:KSEA:KORD:1:1492.9:SEA;
AAL782:KSEA:KORD:1:1492.9;
AAL1848:KSEA:KORD:1:1492.9:;
AAL1360:KSEA:KORD:1:1492.9:;
AAL1804:KSEA:KORD:1:1492.9:;
AAL6796:KSEA:KLAX:13:830.785:;
The First Splitter will be a ':', then the next one will be a ;. Per each line up there, I need to add that content into a row into a datagridview, So if you were to look at the datagridview, It would look like that data above exactly, But separated into the correct columns.

I want to create a simple Hello World or whatever kind of application I want but I don't want it to be a ClickOnce app and I'm using Visual Studio 2010. How would I do this. I'm interested in this because I'd like to have a custom add/remove program icon for my application and not the standard ClickOnce icon that you see. I'd also like to create a custom updater that wouldn't use ClickOnce, and I'd like to bypass all the "Are you sure you trust this publisher" messages that you get when using ClickOnce.

Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string
Do Until Integer.TryParse(Console.ReadLine(), LastName) = False
Console.WriteLine("Invalid input, Please try again")
Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.

I have a solution with two projects. The main project connects to the second project via a reference, and the reference path is local to my machine. It looks like it references the .exe file.So when I publish the main project (ClickOnce), i get the following error:
Application validation did not succeed. Unable to continue.In the log file, under Error Details, it says
System.Deployment.Application.InvalidDeploymentException (RefDefValidation)
- Reference in the manifest does not match the identity of the download assembly Project2.exe
- Source: System.Deployment
How can I include this second project? Should I publish it, then reference the published files? What do i reference? The .application file?Is there a way to just include this second project, so when I do publish the main project, the second one just goes along with it?

I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.

How can I create multiple shortcuts to multiple folders in the same folder?

I'm creating a database installer where I have some code to create database, tables, stored procedures, etc.I don't have problems when creating the database, tables and inserting required data. My problem is when my code gets to the stored procedures section.
Here is what I do:I have different text files (database.txt, tables.txt, insertdata.txt, storeprocedures.txt) where my sql syntax is located.I execute every process/text file using the following:
ExecuteSql("master", GetSql("database.txt")) ' Creating 1 database.
ExecuteSql("mynewdatabase", GetSql("tables.txt")) ' Creating 15 tables.
ExecuteSql("mynewdatabase", GetSql("insertdata.txt")) ' Inserting data to many tables.
ExecuteSql("mynewdatabase", GetSql("storeprocedures.txt")) ' Creating 6 stored procedures.
Here is part of the error:In exception handler: Incorrect syntax near the keyword 'PROCEDURE'. "This is the second stored procedure because the variables I get below belong to the second one"
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
Must declare the scalar variable "@intVariable1".
When trying to create 6 or even 2 stored procedures using the same file 'storeprocedures.txt' is not possible. If I leave just 1 it works but I really want to keep them together.
Creating 15 tables using the same file 'tables.txt' works, inserting data in different tables using the same file 'insertdata.txt' works.This is the general syntax I use:
Create Procedure sp_stored1
@intVariablex int
As
[code].....
Is is possible to create more than 1 stored procedure the way I'm trying to?Do I need to end every stored procedure with specific sql syntax, other than the 'end'?

I thought I'd give VB a go after developing with C# for the past few months. I'm using Visual Studio 2008 and have imported the VB IDE settings. I'm going through the same steps in VB as I've gone through in C# to create my solution for an n-tiered ASP.NET web application, but the results are unexpected. Here's the steps:
1. File > New Project > Other Project Types > Visual Studio Solutions > Blank Solution .... name the solution & choose the location ...
2. At this point, I want to proceed to add projects as follows by right-click on the solution in solution explorer
a. Add > Visual Basic > Web > ASP.NET Web Application ... name / location of the Web Client
b. Add > Visual Basic > Windows > Class Library.. name / location of the Business Layer
c. Add > VB > Windows > Class Library ... name / location of the Data Access Layer
BUT, as soon as I complete step 2a, the solution disappears from solution explorer. "Show all files" is selected. This happens regardless of the project I create first.

I have a requirement to create a multi level treeview in ASP.Net (with VB) but I am completely stuck on how to start this. Currently my treeview is a fixed 2 level approach but now I need to rewrite this to be more dynamic and support extra levels being added into our database tables.So this treeview needs to support as many levels as needed without having to rewrite any code each time we want to add new level, Ideally we will just insert the data at the database level.I think I have the database part designed correctly, I created 2 tables Menu and MenuItemsMenu has 2 columns ItemID and ChildIDMenuItems has 2 columns ItemID and Description Doing this query:
SELECT
menu.Item_ID,
menu.Child_ID ,

I am in the process of creating an array for a set of multiple choice questions but I am having a few problems. I am an absolute beginner at VB and I am creating a quiz that users will select one of three possible questions and then depending on their answer a +1 value will be added to the score. However I do not know where my questions and answers are supposed to go, from what I have read online I have to use (0, 1) format to give possible answers but I do not know how I would make the questions and answers display in textboxes on my form. At the bottom of my code I have also included code to randomise the questions although I am unsure as to if it is correct. At the moment I can run my form fine without any problems but my main issue is to how I will get the questions and answers linked to my textboxes on my form.
Public Class frmTest
Private ran As Random = New Random()
Public intScore As Integer
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
'Turns the message box invisible when start is clicked
lblMessage.Visible = False

Is there a preferred method of creating a file with multiple sections? For example a program for a small retail business that might include different categories of sales, etc.I've come up with a primitive way of separating sections of a text file, which I can read and write right now, but I'm not confident that it will always work. I have a feeling it could produce an error down the road.

The Function will accept 6 diffrenet parameters as Optional. Each one of them will be an additional condition to be added to a where clause, if it`s provided when the function is beeing called.
Is there any method in .NET to simply add a new condition to the where clause?

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.
