Dataset / Datatable In Visual Developer 2008?
Jan 19, 2009
I am developing a Windows-application - database mssql - visual basic.I add Datasets to forms, bind them to daatagridview/textboxes - fill with dataadapter - everything's fine so far.
Here's my question:how do I programmaticaly move from a record/datarow i a dataset to another.I know the value of the key-field and want that record to be shown. If I use the dataset.datatable.findbykey-method, the program finds the record, but it doesn't move there.

I get an error that says Setup Stopped working when installing Microsoft Visual Web Developer 2008 Express Edition with SP1 . Everything else installed fine. I am using the Offline ISO.
EDIT: This happens with the new 2010 Beta 2 also.. same exact error message.
Here are the details:
Description:Microsoft Visual Web Developer 2008 Express Edition with SP1 - ENU has encountered a problem during setup. Setup did not complete correctly.

Google search does not help. What is really funny about this is that from my search I see there are multiple solutions for this problem that have worked for different people, none of which apply to my situation.Why do I get the feeling that God does not want me to learn VB programming? (Grin)

I'm at the end of my tether now.I'm trying to build a website which takes its information from an access database. ASP.net seems to be the answer, so I've downloaded Visual Basic Express 2008 and Visual Web Developer Express 2008 and I'm following a tutorial to learn the basics.
I can't seem to get the OleDBConnection and the OleDBCommand functions to come up in my toolbar. I've created a ASP.net Web Application, a Webform and tried "Choose Toolbar Items", where I've ticked the box for both, but they still haven't came up in the toolbox. This is the last step in what has been as steep learning curve for me.

Ok I can successfully connect to my Access database but I am still learning on how to output that data. Here is the run down.I am designing a page where the user inputs the customer ID and then gets a list of incidents for that customer. Then I would like the user to be able to add a survey about the incident.Problem I am running into is the ability to display this data. I have tried various method. Eventually I want to be able to display the data into a listbox and have them select it and take the survey but I am not near that far yet. Here is what I have on the connection and my attempt which doesn't work to output the data:

I want to put a button on my Visual Web developer 2005 Express edition page (one single web page) that will close the internet web browser (IE 7 being used), when my users click on the closed button. I need to write visual basic code to closer the browser but haven't found an example that explains how to do this in code. Can someone give me an exmaple of how to accomplish this in Visual Basic Code.Paul Mayer

Basically, the question is: Where (and in which format) should I store textual developer documentation associated with my Visual Studio projects?
To elaborate: XML comments are great, but they don't cover all use cases. Sometimes, you'd like to describe the class architecture of the project at a high level, add usage notes to your library or just leave any other kind of message to future generations of developers working on this project.
I'd like to add these documents directly as files into the Visual Studio project, to ensure (a) that they are available to the developer without further searching and (b) they are version controlled (using the same svn/git/whatever repository as the source code).
Currently, I add a folder _Documentation to the project and use text files, but I'm not sure if this is the best solution. Visual Studio does not have an option for automatically word-wrapping text1, and manually fixing line breaks after each change is annoying. On the other hand, Word documents don't work well with version control, and TeX is too much of a hassle to set up and teach on each developer PC.
Is there a well-established best practice for this?
1 I know that there's Edit/Advanced/Word-Wrap, but this only affects the display, not the file itself.

As far as I can work out I should be able to copy a web project/application to my IIS Web server and be able to see it as I do when designing it on my development computer.
The problem is once I copy the folder over to my web server and then try to view it the browser it says Error 404 not found. There must be a real simple fix for this. I would like to be able to develop ASP.NET sites using the Visual Web Developer instead of Dreamweaver but this little issue is stopping me.

I have a web page that has a few text fields, and a reset and submit button. I'm having trouble getting the reset button to work to clear the text fields because the required field validators and regular expression validators are blocking any code in the reset button's click event from occurring. how to get the validators to not activate when the reset button is clicked? One method I tried was to set the enabled property of all the validators to false in the reset button's code block but no luck.

I'm a software developer and use visual basic 2005 and access 2007.Well first programmed with Visual Basic 6 but I decided to switch to. Net and indeed it is a big step.
Finally, in vb6 did not need the database linked to software to generate reports because it filled from a listview as the connection to the database do it for DAO ("C: ProSoft Billiard Data.mdb"). Now the question is as I can if I have to file a report so the connection in my software? is a bit urgent as I have to give and software and I need to do the reports.

I've been using VB for some time now, but I must admit I am a little confused. I started learning with 2002, then 2003, 2005 and now 2008. I think database coding must have been going through a kind of transition when I was trying to teach myself the basics. As a result, I am not entirely clear on a few things..
1) What's the difference between a DataTable and a DataSet. Why would I use one over the other?
2) Personally I dislike using DataAdapters etc and much prefer typing my connections in code so I can see what's what. When using the visual tools things are 'hidden' from view and it's not clear what's going on - do others find the same or is this just me being old fashioned?
3) Using my code-based approach (ie: creating SQL connection, using ExecuteNonQuery and a SQLDataReader to read the results into my application) - is this less efficient than the alternative methods?
4) Finally...LINQ. Is it any better and should I be using it as standard practice?

I attempted to add a ADO.NET Entity Data Model to my Visual Web Developer 2010 Express project and it generates but returns a whole slew of errors. Why is this generating errors? Here are the main errors:'Public Property ID As Integer' has multiple definitions with identical signatures.Method 'Onaddress_IDChanging' cannot be declared 'Partial' because only one method 'Onaddress_IDChanging' can be marked 'Partial'.'_line1' is already declared as 'Private _line1 As String' in this class.

I've just rebuilt my PC and have upgraded to visual web developer express 2010. I have imported my projects which use the charting control quite a bit. Unfortunately my projects are failing to run. In design view the control is now showing as "unknown server tag asp:chart". I can see the Chart control in the data tab in the toolbox but it is greyed out.

I am developing a next gen App for my Email Client for future Windows 8 users. Now when i used to use Visual Studio (Visual Basic) 2008 to develop for Windows 7, I used the command "FORMNAME.show()" And that command would open the form.The Problem i am having now is that "SHOW" is not included and im guessing that there has to be another way to do this. For the Beta version of my app, i created a test Button that i want to open a "SplitPage1" the button is called " btnOpen"?Now to give you an idea what i wanna do, i made buttons on the top right hand corner that are called "File , Edit , View" and so on, and when the user clicks file, i want a spiltpage to open with all the options the user would regularly have when clicking file on a menu tab in a program. the options would be lined up on the left hand side when you hover over lets say "New Email" on the right hand side there will be a short description that will appear saying "create a new email to send" and when clicked on it will take the user back to the mainPage and it redirect the browser to "SendnewEmail url".

I'm working on a helper class that will make things easier for me when connecting to and viewing a crystal report.Now I need to create a Property called DataSource. Crystal has a SetDataSource method that has 4 overloads/constructors(not sure what the right term is)1 accepts a System.Collections.Ienumerable, the 2nd accepts a Dataset, the 3rd a DataTable, and the 4th a DataReader.Now I want my property to be able to accept all those. So what Type must my property be.If I can just have DataSet and DataTable for now it would be fine, as I work with those mostly Public Property DataSource as?

I have code running in the Datatable.ColumnChanging event in my dataset. This dataset underlies a form and conventional drag/drop controls are in place for data entry.when the event triggers and runs, I am running code in the form that checks the dataset.HasChanges property. It is showing False. But this is immediately after the ColumnChanging event has been triggered.Okay, I see by others posts and MSDN that .HasChanges will only be true after moving off the row with the changed column. I have also noted lots of discussion about the advanced binding property of DataSourceUpdate Mode, but that does not address this issue.I guess I can do this by checking the state of the row for the binding source. Just seems odd that the event behind the dataset can be triggered and that does not change the dataset.HasChanges property.
