View 1 RepliesVS 2010 - TaskFactory And Datasets
Aug 24, 2011I have a taskfactory application that generates new tasks where a task is running a project exe file that involves a lot of classes. Part of the task process involves declaring a dataset and adding a single datatable to the dataset which is then populated with content from results of a sql query. This datatable is then used in the next class and involves iterating through the table and deleting the rows it has already used. When initiating a new task I assume that it will declare its own datatable and dataset but not sure if this will work.

VS 2010 Atomic Transactions With DataSets?
Apr 18, 2011So I'm developing a program were, given some data by the user, the prorgam inserts some records into a database. To insert individual records in different tables I use either the standard INSERT method provided by the Table Data Adapter or a custom Insert Method when I want to insert something slightly differently.Sometimes the user would press a button and an operation where different records in different related tables are inserted. Since each Insert is handled individually for by the DataAdapters of each table, how can I manage to bring the whole thing to an atomic transaction way? I mean, let's say for example the User inserts a new Document in the system, the document has one or many Editions. How could i do something like: if the document was not created properly, then do not insert the editions.
View 2 RepliesVS 2010 Datasets Or Handwriting SQL Commands?
Aug 19, 2011Im just starting to develop an application using a SQL Database as the main datasource. Now im wondering is it better to use the in-built dataset adapters or write the querys yourself?
If its better to use the pre-generated scripts by using the Datasource UI, How can i use these datasets on a JOIN query?
Example Join
SELECT column_name(s)
FROM table_name1
JOIN table_name2
ON table_name1.column_name=table_name2.column_name
VB 2010 And Access (Multiple Datasets And Adapters)
Nov 24, 2010Im currently making a program. It loads data from database fields into an combo box. Everything works so far, It just seems to be a mess. Do i need to have all the datasets and data adapters? or can i get away with just using 1 of each. It seems like im doing it wrong, and although it works it seems like a difficult and messy way of doing it.
Also i would like to assign the firshermenID to a variable depending on the fisherman name that is selected in the combo box. When button is pressed: id = fishermanID of the current fisherman (cmbFisherman.text)

VS 2010 Typed Datasets Vs Entity Framework
Aug 19, 2011I just read this post url...Post #2 by jmc states indicates the use of Entity Framework instead of typed datasets.when jmc says something I usually pay attention. I have a large app that I've been converting from VB6 to .Net and I've used mainly typed datasets.It's a single user app that uses an Access database. I'm have no problems retrieving the data from a table or multiple tables and I'm very happy with its preformance.Is it worth scapping what I've done and learn how to use Entity Framework? I should add that I'm near the end of my programming career not the beginning.
View 4 RepliesVS 2010 Typed Datasets Are Created At Design Time Only And Not Dynamically
Jan 20, 2012In a typical session with the program I'm writing, the user needs to be able to access the data in 1 to 500 (maybe) tables (but always only one table at a time). Up to now I've been creating these single table datasets dynamically, as and when required.I've now come across the distinction between typed and untyped datasets (where typed seems to be the recommended option). It seems, though, that typed datasets are created at design time only and not dynamically. Is this correct? Are all of my dynamically created datasets therefore untyped?

VS 2008 - Convert Existing DB Connection Strings From ADODB To ADO.NET?
Jul 14, 2009I have upgraded my VB app from VB to VB.NET and its working fine. Now, I want to convert my existing DB connection strings from ADODB to ADO.NET so that I dont have to use MS Access on every client which runs this app. Currently the VB app looks up into an Access db to get the server ip, username, password etc. I aim to hardcode these values so that I wouldn't need the Access db anymore. Any inputs on how this could be done?

VB 2010 Pro Connection To SQL DB?
Aug 18, 2010I'm new to VB.NET and am trying to do some basic Forms development and am unable to set up a database connection to a SQL Server DB. Here's the particulars:
I'm using VB 2010 Pro The database is on a server (not local). I have administrator rights. The DB version is SQL Server 2000 Enterprise.When I try to add a Project Data Source or try to add a Data Connection in Server Explorer, I can navigate to the test DB I have on the server, but when I try to test the connection, I get an error stating "The file <path and file name> is on a network path that is not supported for database files. An attempt to attach an auto-named database for <path and file name> failed. A database with the same name name exists, or specified file cannot be opened, or it is located on a UNC share."I tried using a mapped drive on the local machine to the server, and a UNC path.I tried Windows Authentication and user name/password. (Same error message in all attempts and combinations.)
Almost all the development work I've done previously has been primarily w/ VBA (Excel, Access, Word, AutoCAD). I connect to the test DB in the VBA environment either thru DAO (ODBC), or ADO.
I guess I'm wondering whether the DB has to be local? Or is there some setup I'm missing? Is it an issue with trying to connect to a SQL 2000 DB? As I said, I'm new to VB.NET development, so I hate to ask a dumb question, but I've gone thru some threads and articles but haven't found a working hook yet.

View 1 RepliesVB 2010 Database Connection Is Closed?
May 9, 2012I have a problem connecting to an access database. I'm currently trying to build a login/register program that reads the username and password from a database and allows login if the specified username and password are found. I have code that will work properly for that so that's not an issue. However, when I make an attempt to register a new username along with a bunch of other things such as email, password, etc. I am unable to because the database connection is closed. The code I'm currently using to open the database connection is :
[code]...
However, when I try to use this code to open the connection to the database, it leaves the connectionstate closed. I decided to then build in as a test, a block of code that would check on load to see if the connectionstate is open or closed. Each time I've run it so far by making a few changes it always tells me that the connectionstate is closed no matter what I do.

VS 2010 Creating Connection To Mysql Db?
Sep 3, 2011I want to add a new Data Source (so I can use it with Crystal Reports) but using mysql, I did this before.
In the left side under: 'Data Sources' and then choosed 'Add New DataSource'Then I choose: Database > Dataset I clicked in 'New Connection' and I changed the first box (with 'change' button (as you can see in the image attached)) to what is showed in the image (MySQL Database..)The problem is, as I type the first letter of any of the textbox's that are below (server, user, or pwd) it closes that form showing the previous form (where I clicked 'New Connection')
Have someone had this problem ?I had a connection there, but since I changed the project from 'Framwork 4 Client Profile' to 'Framework 4' (so I could have the Crystal Report Viewer) the connection has gone and don't leaves me create it again.PD: I'm using dotNetConnector (already Added as a Reference)
