I completed an application and got it to the point where it works fine. I had it setup on a local Access database and now I want to figure out how to connect it to a SQL server 2008 database. I got it setup to a point where the database is connected to app but not sure how to convert it.[code]

I need to convert old .mdb Access files to the new .accdb format.What's the best way to do this in vb.net?
View 1 RepliesI have been developing a VB 2008 application which has been using Access as its database. The app is very far a long with about 30 forms and 45 DataSets I now must change the application to use SQLServer. Unfortunately all of the Table & Attributes names have changed in the new DB. Almost all of the data model has stay the same.
I have a few questions on the conversion.
The ConnectionString is currently pointing to the Access DB. I have entered the new ConnectionString into the Setting tab. What is the best approach to make the change?
I have done some testing to change the Table & Attributes names by using Quick Replace. It seams that sometime when I would do the rename I would lose the TableAdepter on some screens.
What is the best approach to performing the renaming task?
I am looking for a way to convert Access 2003 Forms to VB .NET (2010) forms. I don't care about the code, I can redo that no problem, but the forms have a lot of objects in them and I don't want to recreate them all. Any ideas? Preferably free??

I am trying to convert a C#/XNA project to a VB.Net project with access to the XNA framework. I have added all of the XNA framework as references in the VB project and imported them as well.Most of the code translation is going well but I am getting mixed up with some graphics issues and some event handling issues (neither of which do I understand in any languague). I have tried to puzzle it out but am digging myself a deeper hole with each attempt.I am ok with converting the variable declarations and the first three lines of the Game1 Sub. It is when we get to "graphics. preparedevicesettings . . . " that the trouble starts.

View 2 RepliesI'm having a hard time in understanding xampp. I will need to change my database from ms access to xampp. I already test it in a sample program and it works! Now I want to convert my whole system so my first step is to delete the database in my system (ms access) then create a code that will connect my system to xampp, I'm done with those things. The BIG problems are I'm having 98 ERRORS and I cant figure it out. I dont know the equivalent code to xampp. Here's the code that has error. Note that it is just one of 98 errors in my system.
Me.TableAdapterManager1.UpdateOrder = FinalSystem.FinalDatabaseDataSetTableAdapters.TableAdapterManager.UpdateOrderOption.InsertUpdateDelete
xampp doesnt have any tableadapater, but what should I do to insertupdatedelete?
I am trying to convert a VB5 program to VB2010 so that I can continue to support it on my new PC. My copy of VB5 was an upgrade from VB3 which was an upgrade from VB2 which came on floppies, so I can't just install every preceding version as my new PC doesn't have a floppy drive.I have accepted that I will have to design all the forms from scratch (whatever happened to twips?) and will have to go through the thousands of lines of code line-by-line, but I have hit a brick wall when it comes to random access files. One such file is defined in the Declarations section of Module1 thus:[code]....
I soon found I had to change Type to Structure, but then in the declaration of transrec, transtype acquired a wavy blue underline with the error message: "'transrec' cannot expose type 'transtype' in namespace 'Treasurer_2010' through module 'Module1'.So if I can't use the structure in the module in which it is declared, where can I use it?
My website connects to a Microsoft Access DB at the moment, im about to upload it to the internet - its a VB.NET web application but i'm advised to convert it to MySQL or MSSQL for better performance.How would you recommend I export the DB ? there isn't too much data in at the moment so mainly all of the tables and fields.
View 2 RepliesI have just started using databases, but I am totally stuck. I made a database and table using MS Access. The table has three columns. ID, Code, and Letter. Basically, the Code column stores a number for each letter (eg. 1 = A, 2 = B, 3 = C, etc.)
Table:
|ID|Code|Letter|
| 2| 1| A|
| 3| 2| B|
| 4| 3| C|
etc.
This table is just for reference for my program, and I don't need to change any values. But I need a step by step guide to link this table to VB 2010 and convert the values of the table to an array. For example: convert the table into the array "example" which means that example(1) = A, example(2) = B, example(3) = C and so on.
I'm trying to convert an old Quick BASIC program to VB.Net. There doesn't appear to be any direct replacement for the old file statements. Building a database seems like overkill for my simple needs.
How can I do the following in VB.Net?
OPEN "test.dat" FOR RANDOM AS #1 LEN = 20
FIELD #1, 10 AS a$, 10 AS b$
LSET a$ = "One"
LSET b$ = "Two"
PUT #1, 1
GET #1, 1
PRINT a$, b$
CLOSE #1
my goal is to
1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)

My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

View 5 RepliesI have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden.

View 4 RepliesIt is a program on which logic programs can be developed, compiled and downloaded into Programmable Logic Controllers. It is fairly big and complicated and the resulting .exe file is about 2Mb. I need to develop the program further now, and would like to use VB.net. When I try loading the VB6 code into VB.net, it changes all the variables of type Integer and String into type Object. It then states all through the resulting code that the default values are not defined. I assume that if defined as Integer and String variables do not need a default value, it would assume them to be 0 and empty. Any ideas why the program changes the variable types during the converstion? All forms start with 'Option Explicit', so all variables are defined.
