I am working on what appears to be a very simple application but have a problem that I can't seem to get around. Using Visual Basic 2008 and an Access database. My application starts with only 3 text boxes and using the Data Wizard it works fine. I want to expand it to give the user a way to select an individual record to review so I dragged a ListBox on to the form onto the form, filled the DataSource and DataMember properties and When I run the program I click on one of the items in the List Box and the proper record fills the Text Boxes.
I am Wajahat and I am a VB .net novice. I am unable to connect vb .net to database because my wizard is not working properly. When I Click on Add New Data Source ---> Database ---> New Connection, no dialogue box appears asking for the database source.Secondly, When I try to click on "Connect to Database" in Database Explorer, an error message pop ups saying "The event log is full"..I know no alternative to connect vb .net to a database. Please help me sort this problem out.
How Do I show the values from the dataset to the text box based on the selection from the combobox list i already populated the combobox my code is. [code]
In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?
i want to create new data connection using data configuration wizard..when i click on add new data source i looks normaly and wizard started..when i got into "choose your data connection" window and click new connection, windows closed and nothing else was going on..no response, no alert window..nothing..
I have recently installed Visual Studio .NET (Pro Edition) and I have tried to run the Data Form Wizard and get an error after entering the "Name" for the dataset and hitting "Next". An error message pops up and says "An unexpected error has occured: Specified argument was out of the range of valid values.Parameter name '0' is not a valid value for 'index'.
I have a program on my machine that uses a local SQL Express 2005 database to store information in when the program is running. I want to use some data within said database in my program but for the life of me I cannot seem to get started by adding it as a new data source using the add data source wizard... If I type in the database name it throws an error that it cannot find the database, although I can quite clearly see it using the SQL Express 2005 SQL Server Management Tool.
I am currently working on a project that involves the use of data base sources, namely ODBC. The problem is I have designed a form using the Data Source Configuration Wizard that doesn't update. I've ensured that I have a primary key in my data and that the Copy to output is set to "Copy Always". The code generated by the wizard, is as follows: Public Class Form1
I'm just in the process of upgrading to the .net system and beginning my first database project.When i try usng the Database connection Wizard i get the following error "See attachment"The data base is a .mdb file. Seem to work fine in VB6
New to VB... I am trying to access .SYS (system files) located in the following folder path (example) My Database NameVIEWSSYSTEM VIEWS in the Object Explorer of my SQL Database. In walking through the Data Source Configuration Wizard for data connectivity I select DATABASEVIEWS and the SYSTEM VIEWS sub-folder is not available for selection. In general: What is the best method to access System Files using VB Data Source?
I am a brand new user of MS Visual Basic 2005 Express and MS SQL Server 2005 Express. I have familiarized myself with both programs but have one extremely frustrating problem. Once I open SQL Server, I can not establish a database connection from Visual Basic using the Visual Basic Data Source Configuration Wizard (even if I close SQL Server). If I reboot and open Visual Basic first, I can then connect using the Visual Basic Data Source Configuration Wizard. But then I can not switch to SQL Server and open the database (even if I close Visual Basic). Again, I must reboot to open the database in SQL Server.I suspect there is a setting somewhere that needs to be changed, but I can not find it?
I am looking to make a data connection with a network server(sql server 2005). When I run the data source configuration wizard, it allows me only to pick a local database file. I want to use a connection string like this "Data Source=SQLSERVER;Initial Catalog=mydb;User Id=username;Password=password;" I know I can do that programmatically. But I would like to know whether I can do that using the data source wizard so that I will be able to use Bindingsources and tableadapters.
Got a form linked to a database and i have the first column of data appearing in a list box on my form. In the database there are two records with the same value and so, of course, in my list box the value is given twice.How do i remove this repetition from the list box? (still keeping it the same in the database)
I've got a database with the fields: tuneName, Artist, Sales and yearIssued I'm trying the load up just the first field (tuneName) into a list box. I've managed to load the database into VB but I dont know the code to do this specific thing.Also I want to be able to select one of the items in the list box and the rest of the fields to appear in text boxes on the form.
I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?
I'm writing a database program that will take various information from the user via text boxes, then save them as a *.txt file. I've already figured out the majority of that business. However, I'm having trouble programming a ListBox.
The ListBox needs to accept three pieces of information from 3 Text Boxes, then concantenate them when a button labeled 'Add' is pressed and scoot them to the ListBox (lstshowresults) while clearing the three boxes at the same time.
I recently switched to V.Studio 2008 and using VB. I can not find in the data toolbox the connection and data adapters. Should I do something else to make this appear so I can drag them in my form.
I am using the TableAdapter Configuration Wizard and under Advanced option I click on "Refresh the data table" and carry through to the end of the wizard. However when I run my code and want to update the dataset on the form I get the error message "Update requires a valid Update Command when passed with DataRow collection with modified rows". So, ok, when I look back at the Dataset with right click and configure I find that that the "Refresh the data table" under Advanced Options is no longer ticked, even though I had ticked it before and finished the wizard. Somewhere along the line the tableAdapter is losing this value.
I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.
I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.

Ive been trying to figure out what report I should use as it appears I have crystal reports built in and also have Microsoft Report Viewer in this VB 2008.What I need to do is give the user a list of names and when a ame gets clicked it will show all the details in a report.I have loaded a ListView Control with the names from my database and this is letting the user pick a report so I can get the name and ID number of the record to show this way and just need to figure out how to get that record onto a report and what report to use?Ive done similar in VB6 but have never looked at .Net. The data is comming from an access database.
This is what I'm sure will be the first of many noob-ish questions from yours truly... I'm studying as a mature student for a Computing Degree (encompassing web design, hardware, programming and systems analysis). The programming seems to be my weak spot this year. I enjoyed C++ last year, doing basic console applications, but progamming visually with VB in Visual Studio 2008 I'm struggling!
I have added a list box and now i need help to display the data about my employees in the list box. How am i supposed to do that, do we have to put in codes or need to use that small arrow near the list box.
I'm an instructor trying to use data from a .txt file to list the grades in a list box. I just want to grab the data from a .txt file, list the total amount of grades in a list box, the mean (avg) and the standard deviation.
