VS 2008 What Type Of Project To Chose To Get Stuff Done On List
Oct 25, 2010
I am quite new to the VB scene, and am still quite confused by the variety of options presented as far as choosing the correct project type.I have been coding for roughly 4 years now and consider myself still to be a beginner. My past experiences include, hmtl, C++, vba, assembly, and a few others which I'm sure currently escape me.However, VB is a whole new boat and I'm just not sure where to get started with what I want to do.I've Googled the internet, went through the MSDN, and even did some tutorials.My current dilemma is I wish to make a program that will do a the following: Allow a User to download a set of data from an embedded web page.Open an excel file Download more data from a different web page.Open another excel document..I'm sure this is probably quite simple to do (read: I hope...). However I'm just not sure where to begin as far as choosing a project type. Additionally I'd like to have it set up with buttons, where button1 reads something along the lines of "Step 1: Click Here to Go and Download Data", "Step 2: Click Here to browse to excel file", etc etc.What type of project do I chose to get the stuff done on my list?

In games such as Warcraft III, you can play against players on LAN, and it can show a list of games being hosted by people on LAN. There is no central server that holds the entire list, so how does it get the list of games? And also, how would I code something that creates a game on LAN, like a bot?

I need to read data from an Excel sheet as part of a data conversion. Certain columns contain mostly numeric data but may contain some alphanumeric data somewhere in the excel sheet. The problem is, my conversion sees the alphanumeric values as null (or blank. Using the .ToString() method returns ""). To connect to Excel, I'm creating an oledb connection, creating an OleDbDataAdapter, then filling a DataSet with the adapter.
Here's the VB code for connecting:
private _oleadpt As OleDbDataAdapter
private _oleconnection As New OleDbConnection
Dim olecomm As OleDbCommand
'_database comes from a settings file and is the full path to an excel document
Dim connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & _database & ";
Extended Properties=""Excel 8.0;HDR=YES;"""
[Code] .....
I think the data adapter is determining the datatype for the columns based on the first however-many rows it looks at. It decides the columns with numbers are numeric which is the start of my problem. Changing the formatting of the column in Excel doesn't seem to affect the datatypes in my data set. Is there a way to tell the dataadapter or dataset what type of data to use for a column? Or should I try to cast the data in my SQL statement?

This may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name.
Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.
[code]....
Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.

Ok i'm trying to declare a global list of type T (or is it <anonymous type>) i declare it in a module with something like Friend query As New List(of {whatever type i try}) the app takes some xml and parses it into a list but i need this list available to other classes and methods within the app, everything i have tried fails resulting in an error like Value of type 'System.Collections.Generic.List(Of <anonymous type>)' cannot be converted to 'System.Collections.Generic.List(Of {whatever type i try})'.
What would be the correct way to declare a list of this type? is there another way i could do this?

When you use List(Of ) you can add different data types to that list, and a while back I remember JM told me to make a new type to list or something and I was wondering how to do that. I want to be able to make a list that has a large amount of text and each item is named so I can gain easy access to that item.

I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions:
1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page.
2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I tried to use just a text box but that isn't working right.

Oh - and before anyone asks - I tried resetting the visual studio settings

I seem to have a major problem. when I add a typed dataset to my project and go back to my sql server and click on the databse I use it doesn't open. the tables and stuff just vanish. using the wizard, it creates this connectionstring:
<add name="Schenectady.My.MySettings.SISQL2ConnectionString"
connectionString="Data Source=.SQLEXPRESS;AttachDbFilename="C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataSISQL3.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
It connects fine. but after I try opening it in sql server i get an error. It doesnt let me restore or anything. i tried restarting my pc incase the db was locked but it is still gone. now my app cant connect. Just for clarity, is user instance supposed to be set to true. and what is the purpose of it. also when the wizard asks to make a copy of the file that will be copied accross each time I run my project I select No.

1)How can I make my program get the contents of a .txt file on my website to tell the program to run or not?Here is and example of what I want:Say the file says "Running", the program would run without problems.If the file was to say "Unavailable", a pop up would appear saying "The program is currently unavailable, try again later." Then once the person clicked OK, the program would close.
2)How can I make the program get contents from a .txt file to get the latest version of the program, then if there is a newer version, there would be a pop up saying there is a newer version and they need to update. Then when they clicked OK, the program would close and it would open their default web browser or Internet Explorer to the update page.

For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

I have 2 projects, one built in VB.NET and another in C#.NET. I want to use certain functionality of VB.NET into C#.NET and hence I have added the dll file of VB.NET solution into C#.NET as a reference by browsing the dll from my system. Say dll name for VB.NET is myData.dll. In my C#.NET project I am trying to declare it as a namespace i.e. "using myData;" and its giving me an error of "Type or namespace name could not be found"

I am working to a big solution that is almost finished. The language interface is Romanian. Now I have a problem because I have to make an option at login in which user can chose the language - and I have to create all the software in Romanian and English languagesd.
My intention is to create inside of o database (because my application is working with an sql database) a table named lang_tbl and in which I will put all the words and text that I have used in the application in romanian on one columnb and in English on another column and when I start the application I will load all the rows from the table in an array together with the unique ID's. And in runtime I will use the unique ID for every text that I have in the application.

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
