I'm building an aplication with an MS Access database behind the scene. In many of my forms I'm gonna use DataGridViews to show data from the database, not an entire table but data based on manually built queries. So, I have few questions without answers, by now. Solutions or 1. I haven't decided how will I bring the database into the project: from the menu -> Add New Data Source, or within the code, at runtime. I still don't know which one's best or why.2. How exactly can I execute any SQL query (SELECT, INSERT, UPDATE, DELETE etc) on my Access database from my aplication?
I am trying my hands on VB.net and is trying out a small application which includes a survey form. The form contains radio buttons and when the respondent clicks on a radiobutton, digit '1' should be placed into the relevant field of the database.I have established a dataset and tried doing it but not sure how to do it because the book (How to program Visual Basic.Net by Dietel) does not teach us that
I am asked to write a front end program in VB 2005 (that will run in client computers which running on Win XP) to access an existing MySQL database running in Linux. It is not my preferred choice, but the user have the database and server working just as he wants it, and do not wish to change, at the same time I do not wish to change programming language. Is that even possible? Can we actually write VB 2005 programs that will run in client computers complete with NET framework 2.0 to access a Linux operating database?
I want to move my programs and the database to another computer and hard-disks. It looks to me as though I nearly have to re-create the controls and rewrite some of the code to make it so the programs still work after the move. At least with ODBC all I would change was the DSN definitions external to the programs. Is there an easy way to move or rename a database without loads of work?
I am using Visual Basic 2005 and am trying to get my database in Access 2003 to connect with it. I have mannaged to connect my databse, but I don't know how or what commands are needed to load my database.
I'm looking for some simple code that lets me create a Microsoft Access table via code.Currently all I do in Access is write and retrieve data from specific tables but now I want to be able to create them at runtime. Here is an example of the code I use to load some data just so you can get a feel of what I'm currently doing. Hopefully there is an easy way using the same rough way that I'm currently dealing with databases.
Code: Public Sub LoadCareer() Public rs As New ADO
For years now I have been using access as my database. But with the SQL server Express version around I have been wondering if it is not better to use this instead of access. Note: I only develop applications for small businesses and a limited set of users. So what do you guys prefer and recommend?
---3 laptops running same VB.NET application locally AND access/share same database located on one of these machines. Is this Possible? an easy way? ---OR would the best sollution create a website with database ?
i have an ACCESS database with 3 columns. I establish the connection with the VB 2008 Express and put the data in the form but i don't know how to add the text of a textbox in the database.
I installed Visual Studio 2008 and Office Enterprise 2007 in my new computer.I made some codes for a data reader to get data from an Access dabase. On the step where it will open the connection an exception appeared which says "Microsoft.Jet.Oledb.4.0 provider is not registered on the local machine".
I'm trying to query an access database, but my query results only display the first cell of the query results.
For example, if I select 3 columns, 5 rows, only Column 1 Row 1 is displayed. Someone mentioned something about EOF but I can't find EOF code for OleDB. Should I be using another type of connection?;
Code: Private Sub btnGetReport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGetReport.Click Dim StartDate, EndDate As Date
I wanna create an access database programmatically.How should this be done?Do you recommend that I do it via code?I don't know how to create an access 2003 compatible file at run-tim
I'm trying to create a database driven application using VS 2008. I want my database to be generic, i.e it shouldn't rely on the existence of MS Access or similar application. So how do I create such a database, add tables , values..etc?
I need to update a database app written in VB, Visual Studio 2003, using an Access Database.Currently: Customer has 4 users, local network. Access Database is 30MB, about 50 tables.Wanted: Customer is opening new offices, and wants to connect to the database via the internet. There will be 10-15 users.App background: I have all data access via OleDbDataAdapters and one OleDbDataConnection.There are 4 DataSets: Global, Lookup, Reports, FormSpecific.
I have one Private function: FillTable:
Private Function FillTable(ByVal TableToFill As DataTable, _ Optional ByVal OleDbAdpToUse As OleDb.OleDbDataAdapter = Nothing) As Integer ' fills the table by using OleDbDataAdapter.Fill(aTable)

All is working well.What I Need to Do:I think I need to migrate the Access Database to MS SQL. What I Have:Visual Studio 2008 Professional. I have started the MS SQL walkthroughs. I did the �Create a Data Connection to the Northwind Database� walkthrough, and connected via MS SQL Server. I cannot find where I can modify the SQL Commands. If I convert my Access Database to a MS SQL Database then can I
1) Just update the OleDbConnection, so it connects to the MS SQL Database (not the Access database).
2) If I cannot do #1, what do I need to start with?
I'm making a Monopoly Game which i'll make sure i post up here when done, I'm using Visual Basics 2005 and OLEDB Connection, i know how to work all that but i have the following scenarios to find SQL for.
Upgrade Property - I need to use the Update Query for this. A PropertyName is selected from a list box and someone then clicks to upgrade a property.
Properties.HousesOwned should have it's value raised by 1 Where the player owns all 3 sets. The Houseprice should then be took off the Players Money.
Downgrade Property - I need to use the Update Query for this. A PropertyName is selected from a list box and someone then clicks to downgrade a property.
Properties.HousesOwned should have it's value lowered by 1 (until it gets to 0) Where the player owns all 3 sets. The Houseprice should then be added to the Players Money.
I'm new to Visual Basic. I came across a random number generator tutorial. Got it working fine and then I thought, Is there a way to get it to access a database Here's the thing
1. Generate the random number. 2. looks at the database and finds the corresponding id number. 3. Takes the field for that number and enters it into a text field in the program.
So for example the number generated is 32. Then the program looks at the database and looks for id number 32. then takes the text in line 32 and enters it into a textbox in the program.Now I have my database and the program. But just can't seam to figure out how to get the two connected like I want. I have looked and searched but have found nothing like it I am using Visual Basic 2010 and Access 2007.
I'm working on a VB.Net Windows form that is supposed to manipulate an Access Database. I can Already read data from the database (placing them in a combobox) using the following:
Code: Private Sub Form2a_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load OpenFileDialog1.FileName = "" OpenFileDialog1.Title = "C# Corner Open File Dialog"
I have recently wanted to start work on an application that uses an MS-ACCESS database. The problem is that no matter what I do, the actual database will not retain any records added. I have followed the Microsoft examples to the letter and it does not work. As long as I have my app running I can add, edit and delete the records. As soon as I close it and run it again, all the records are gone. The mdb is not read only, I've checked it. I also decided to try the my video collection example program that is included with VB 2005 and it will not retain any records either. Is there any code I need to add to get this to work or is my copy of VB 2005 broken? This is extremely frustration because I plunked down a lot of money for Visual Studio 2005 Professional. This is a key feature and it should work. Microsoft had me do a reinstall and apply a couple of patches and it still did the same thing. They told me either I am not coding it right or my system is flaking out. I did a fresh install of Windows (I even formatted the drive before installing), and reinstalled VS yet again and even with that being the only program on there, it still will not work. So I installed all my programs again, restored my backups and now a day and a half later I am writing this.
I have two tables in the MS Access 2003 database " SAMPLE" and they are : 1. INFO 2 INFO2Now i have created a form in VB 2008 express edition with the text boxes: Name, Age, Occupation.he tables INFO has - Name, Age as columnsAnd INFO 2 has - Name, Age, Occupation.All i want is when the user presses the ok button, it should add the name & age to INFO and also add Name, Age Occupation to the INFO 2 Table.
I've been googling to find a guide on how to access a database with visual studio.I cant find anything complete or up to date. I should point out that I dont have a great deal of experience with SQL.I'm not really 100% sure where to start. Most of the guides I've found tend to assume your accessing an existing SQL database and I need to set one up from scratch. I'm not sure if I'm even setting SQL server up correctly. point me in the right direction on where to get started. A good, up to date tutorial would be great.
For my purposes the SQL database will only be written to from the local machine but there will also be another machine writing to this database.I'm currently using Visual basic Express 2010 and SQL Server Express 2008 R2, mostly because they are the most recent when I googled it.
I have developed a Windows Forms application using VB.NET and MS SQL Server 2005 Express Edition. My database name is 'AC'. I do not want ANY user, SQL Server or Windows authenticated, to access, read, write to, update, drop or take backups of this database, except this login 'Adel'. So my connection string looks very similar to:[code]What configurations should I make in the MS SQL Server Management Studio 2005 Express Edition to 'Adel' login, 'AC' database, and all other logins to accomplish this?Given the following:I do not own the server; my client owns the server. They have a domain set up (LAN network).They have ASP.NET applications running using other databases on the same server. However, these applications have nothing to do with my database 'AC' or login 'Adel'.Some of their applications do not specify 'User Id' in the connection string; they use 'Integrated Security=True'.
Usually, to go through my Access Database records in VB, i used the "Data control tool" in the older versions of VB, but i cant find it in VB2008, is there anyother tool that allows you to scroll through Access database records, on VB 2008?
I use the following code in vb.net to search across several Access database fields, which works well, is there a way to find out WHICH field had the search data in?
[code] Public Function Incomming_Number(ByVal strNum As String) As String Dim oConnect As New OleDbConnection Dim sql As OleDbCommand
I'm currently looking to add a code where, when executed, finds the appropriate value (searches for it), then on the same line, but in a different category, changes the text to 'YES'.
I am trying to insert a variable in Decimal type into an Access table. When I use "decimal" field with 0 digits after the decimal separator (,) my program works properly. However, when i use the field with 2 digits after the separator I get a "Data type mismatch in criteria expression." exception. This happens also when I try to update the table. The debugger shows me that my variables contain the right values but the update or insert command gives the error.
I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code: mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
I have 2 databases that I am working with. One is a compant customer database and the other is my personal call log. Now I am creating a front end for the Call Log. I was updating my customer list by Importing 2 tables from the customer database, a series of queries would erase all of my info, take all the data from the imported tables and move it into mine then erase the imported tables.
Im trying to accomplish the same in my VB frontend. I can connect and fill datasets from the customer database. I can erase my tables. How do I take all of this data from the newly created dataset and move it over to my empty tables?
