Place Connection String In Model Or GUI?

Jul 27, 2011

I have a VB.NET 2010 solution, that contains 2 projects, a class library and a Windows Forms Application.The class library basically is a model, used for doing database integration. I currently have the connection string placed in the class library project settings, but they do not seem to be listed anywhere in the config file of the application. What's the best practice for retrieving the connection string in the class library? I don't want to use a singleton. Should it be stored in the application or class library?

Get A Query String From A Shared Function In A Code-behind Model

Dec 10, 2009

I'm trying to get a query string from a shared function in a code-behind model using VB.NET. You have to use HttpContext.Current.Request.QueryString("Query") in order to get it from a shared function, however doing HttpContext.Current.Request.QueryString.Count gives back 0, which obviously isn't right in my case as there's many that exist. Is there some sort of issue with using this static call from a shared function?

Winforms - .net Connection Entity Framework Connection String Security?

Sep 3, 2011

I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?

Invalid Connection String When Modifying Tableadapter Connection?

Jan 19, 2011

I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.

For the gist of the application:

In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.

I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.

Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim DBConnStr As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security

Correct Place To Format A String In .NET?

Mar 18, 2009

We have a field called employee number in our database. It is char(10) field. we are storing the numbers right justified. so we are storing the numbers as "1", " 2" etc. I am not sure why we started doing this because it happened before I started working here.

Because of this, each function in the business logic that has an employee number as one of the parameters needs to right justify the number. If we forget that, it won't update the database properly.

My question is: Is there a better way to do this so that we don't have to format the number in each function?

Forms :: Split Long String By Character Place?

Mar 9, 2009

I have a String with 15 places that I would like to split into 3 pieces: (First 3 digits), (next 3 digits), (remaining 9 digits).

How in VB2008 can I do that? Everything I have read so far indicates seperating by a certain character (ie: "," or " ") but no mention of character place. Seems like a simple thing, but after 2 hours of searching I'm still coming up empty

Grab Different Pieces Of A String To Place Them In A Different Order In A List?

Oct 7, 2009

I seem to have a huge issue right now trying to grab different pieces of a string to place them in a different order in a list. Unfortunately i can't just find the placeholders for the strings and extract the data that way so i was using indexOf to find commas in the string provided. the problem i'm having is that i can assign the first comma and extract 0 - "," but i'm stuck on how to progress the indexof so it will move through the string submitting everything between the comma's.

VS 2008 Navigating My Code - Flow Can Jump From Place To Place

Mar 11, 2010

Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.

Add A String Item, Returned From Another Form To A List Box At A Specific Spot In Place Of Another?

Nov 22, 2010

there's a list-box with items, and say you want to modify an item in the middle of the list. You select that item and click "Modify" button and a new form appears with the previously selected item data from first form ready to be modified in a text-box. After modifying and clicking Ok the second form suppose to return that modified string to the first form and insert the modified string into the same spot instead of the originally selected item, so it looks like it was edited to the user.

Place All The Objects In The Same Place On The Screen

Nov 30, 2011

I am learning Visual Basic 2010 and I am working on a space combat program for my own education and amusement (a simulation of the Honorverse space combat system). I have a routine to add ships to the enemy ship roster and then place them randomly on the viewscreen. When I step through the sub with the debugger, it works fine, but when I run it without stopping, it wants to place all the objects in the same place on the screen. It's actually assigning 2 random numbers pertaining to the size of the viewscreen and assigning those numbers to GameObjectScreenLocation through GameObjectWorldLocation.X and GameObjectWorldLocation.Y. The objects are fully initialized to 0 in their constructor, FYI. Code is below:

Changing The Connection String?

Dec 15, 2011

I'm trying to change my connection string to w/e the user wants. After a few tips here and there, this is what I've come up:

1: In my settings I've added - Name(login), Type(String), Scope(User), Value(Nothing)

2: Here is the code I'm using

Private Sub LoginForm1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Here I'm checking if the login in my.settings is there
'If not, I'm going to let the user choose what database

[code]....

The error I get is: Format of the initialization string does not conform to specification starting at index 0.here -

Dim con As New OleDbConnection(My.Settings.login)

When I have my con equal to when I added the datasource from it works.
