Asp.net - Entity Date Modelset Generates Errors In Visual Web Developer?
May 15, 2010
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.
ByRef vs ByVal generates errors!?I had a method that used an Object Function Foo(ByRef bar as CustomObject) as Boolean this method generated errors, because some strange .NET Runtime things changed the bar object, causing its Dispose()al.A lot of time spent to understand the thing(where the ... object is changed), until somebody replaced ByRef by ByVal and object wasn't change anymore when passing to this method.As in my case the function Foo does NOT modify the bar, shouldn't ByRef or ByVal have the same effect?[code]
I support small local customers with VB2008 and MS Access applications (not VBA!). When I had to replace my machine, the new one came with Win7 64bit. Things failed immediately. I figured out how to compile VB for x86; but when I did that, I got a bunch of compile errors from the designer code, not my own. Typical of the errors is this one:
===Overload resolution failed because no accessible 'Add' can be called with these arguments:'Public Function Add(name As String) As System.Data.DataTable': Value of type 'Lozier01_PaintInventory.ds.InventoryDataTable' cannot be converted to 'String''Public Sub Add(table As System.Data.DataTable)': Value of type 'Lozier01_PaintInventory.ds.InventoryDataTable' cannot be converted to 'System.Data.DataTable'.
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 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
im try to do a profile page in my website. has anyone done one before and if so have they any sample code i can look at im using sql 2005 and visual web developer 2008
I am C# developer and now I am involved in some large, already in production, project that is written in Visual Basic.NET.I am trying hard not to write in C# and use some automatic conversion tool to Visual Basic.NET. I want to be able to read and write fluently in Visual Basic.NET QUICKLY. I can write and read VB.NET but it is not so easy like writing and reading C#.
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.
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 am trying for the first time, to create a web application which uses xml files to store data and I cannot get it to function right.On a web page I have a Label (label1) which I need to reflect the cityname of a zipcode typed in a textbox (textbox1).From another webpage I have tried this example (But I cant get it to work how to read and write data from an xml file in Visual Web Developer 2008 ???:xml File <?xml version="1.0" encoding="utf-8" ?>
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'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.
I tried numerous times to install visual web developer express 2010 on my new Dell with Windows 7 32 bit but it simply fails to install the VC 9.0 runtime file.
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.
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:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim sql As String = "SELECT [Title], [Description] FROM [Incidents] WHERE ([CustomerID] =
In CRUD application development we have to face the issues with concurencies in Ids such as Generate and display UNique EmployeeIDs on forms. Currently i'm writting .DLL file that has a class that will handle concurrencies.
But i'm puzziled with the Question, is this concurrency handle is part of the software developer or Database developer?
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 receiving an error when trying to query a range of dates from a MS SQL DB in MVC Entity Framework. Unable to cast the type 'System.Boolean' to type 'System.Data.SqlTypes.SqlBoolean'. LINQ to Entities only supports casting Entity Data Model primitive types. This is our query:
I am using Visual C# 2010 Express and Visual Basic 2010 Express on my Windows 8 developer preview PC.Before, there was no problem, both VB and C# work fine.But today, both VB and C# can't handle errors. I have created a simple application with VB and C#. (.Net framework 4.0) the codes are here:[code]But visual studio shows the dialog shown in first image instead of this dialog. So, I can't debug my program.If I enable break exception when thrown in Exceptions dialog, the problem solves, but at that point, visual studio breaks on EVERY exception , even handled exceptions... I don't want to break on every exception...
I am using SSIS and I need to transform a date. How can I transform a date in String format (e.g. 14/09/1980) to the same but in date format in VB.NET?
I would like the datetime format to insert it into a SQL database.
I have a weird problem that seems to of started happening yesterday afternoon. Basically, VS seems to of decided to act as if I had set like a "On Error Resume Next" style rule where instead of telling me about exceptions it just ignores them completely.For example, I just created a fresh new project and stuck this in the form_load event:
I am connected to an access database which uses a text field to hold dates called 'Chased' which i cant change to a date field. I want to find all the rows which are either null, empty string or the date value is less than todays date. I tried cdate but i get the null value error as expected, is there a way of doing this.
I have a large solution which contains a mixture of C# and VB.Net projects.If I get compilation errors because a project which several other projects depend upon fails to build, it is very hard to see the actual error(s) because of the number of VB errors in the error list window in Visual Studio. C# errors found in the projects I compiled show in the error list, but all VB errors appear (including in those projects I have not just compiled).Is there any way of turning off this behaviour so that VB errors only appear for projects that I have explicitly compiled?
I was woking on a windows app today when my errors were no longer being displayed as they usually would, instead the debugger just jumps out of the method. It works in other projects, I have put this: 'Dim i as Integer = "A"' in as my first line to try and raise an error but it just exits the sub on that line.
The output window makes a note of the exception but the usual popup trace does not appear, any ideas how I get it back??
