I have a dataset in a project which I'm using to provide databinding for winforms controls. Everything has been working fine (tableadapters with select, insert, update, delete methods provided by stored procedures) until I added another tableadapter this morning.
Since adding it, every tableadapter in the dataset broke. My project now has 63 errors reporting errors along the lines of :
Error 60 The type name 'SelectCompanyStatusesDataTable' does not exist in the type '..Search.Presentation.dsSearchTableAdapters.dsSearch' C:\Data\Visual Studio Projects\.\..Search.Presentation\dsSearch.Designer.cs 32210 33 ..Search.Presentation
(Using and to censor sensitive names)
I'm at a complete loss with regards to what has gone wrong, let alone how to fix it.
I'm wondering, has anyone seen anything like this happen before and maybe provide a few pointers for what direction I shoulod be looking in?
I know this is an old question but this just happened to me and I managed to fix all the compile errors by clearing out the MyDataSet.cs file (not the MyDataSet.Designer.cs file).
The MyDataSet.Designer.cs file has the following:
namespace MyNamespace {
[.....]
public partial class MyDataSet : global::System.Data.DataSet {
.
.
.
and the MyDataSet.cs file is usually empty (from looking at an old version). But for some reason (I think maybe double-clicking in the dataset designer while adding a new tableadapter), the MyDataSet.cs file had the following contents:
namespace MyNamespace.MyDataSetTableAdapters {
public partial class MyDataSet {
}
}
which, as you can see, doesn't match up with the definition in MyDataSet.Designers.cs.
Clearing MyDataSet.cs removed all the 'The type name 'MyDataTable' does not exist in the type MyNamespace.MyDataSetTableAdapters.MyDataSet' errors.
I know this is old but I found this by googling so hopefully it'll help someone else out!
I have only encountered this after an unsuccessful attempt to rename a dataset's namespace -- the namespace and classnames in the auto-generated and manually generated partial classes didn't match.
In the end I went for a scorched-earth policy and created a new dataset with a slightly different name, and used cut and paste to get the items of the designer in the original into the new dataset. I then deleted the original and updated all references to use the new one.
Thanks...this just happened to me as well.
I used the rightclick "rename" on the dataset.xsd to rename a datatable and adapter.
Blew everything away.
bummer....last couple hours gone.

It can happen if the connection string in the project settings changes, before a schema modification too. I know because it happened many times where I worked. I am an expert at fixing data-sets and also know some run-time work-rounds.

For one of my internship mission, I need to use a C# app-builder, serenity.is with Visual Studio 2015. I'm following this official tutorial.
More precisely, I followed the begin of the tutorial p 43. (I'm just adapting it to what I do, I join the code at the end of the post).
Nothing is going wrong till p 49. The code generator of the app-builder, sergen.exe, is creating some code (I don't have the detail of what he creates but it doesn't seem to be important).
They ask me to "rebuild all", what I did, and everything should work smoothly.
As project is modified, Visual Studio will ask if you want to reload changes, click Reload All.
REBUILD the Solution and then press F5 to launch application.(tutoriel)
Nevertheless, when i compile and execute my code, I've got a bunch of syntax error which shouldn't happen.
You can find the code of my migration file below, but I don't think it is the problem.
using FluentMigrator;
using System;
using FluentMigrator.Infrastructure;
namespace Serene3.Migrations.DefaultDB
{
[Migration(20170802070000)]
public class DefaultDB_20170802_070000_TcpDump : Migration
{
public override void Up()
{
Create.Schema("tcpdump");
Create.Table("TCPDump").InSchema("tcpdump")
.WithColumn("TimeStp").AsString(16).Nullable()
.WithColumn("IdTransmission").AsInt32().Identity().PrimaryKey().NotNullable()
.WithColumn("IdSource").AsString(32).Nullable()
.WithColumn("IdDestination").AsString(32).Nullable()
.WithColumn("PortSource").AsString(16).Nullable()
.WithColumn("PortDestination").AsString(16).Nullable()
.WithColumn("-->").AsInt32().NotNullable()
.WithColumn("<--").AsInt32().NotNullable();
}
public override void Down()
{
}
}
}
I tried to stay as close as the tutorial as possible. I probably forgot to do something, but I can't find what.
Is there any Serenity user which could help?
Feel free to ask any other details
Make sure that all column names are supported by the tool. Column names like "-->" and "<--" would need special syntax in SQL and can't be used as property names in generated code files.
Use property-ready names without special characters or spaces. If you need special names, consult the tools documentation and make sure to use supported techniques.
Sorry for the noob question. im new and i cant figure this out on google.
The thing is, i used to right click the project go add > new item > ADO.NET Entity
and then i choose to generate it from database , afterwards i start using it by typing :
TheEntityName something = new TheEntityName();
but now, for some reason, whenever i type the entity name i get an error that says that it doesnt exist in the current context ?
any idea ?
You need to know the namespace of your entity. Once you know that you have two options. One is adding a using statement in your view
#using namespace
Or use the fully qualified name...
Namespace.entity
I have been dealing with this for a couple weeks now, and figured it was time to bring someone else in. I have been to many sites trying to solve this, but I'll start from the beginning.
This is my first project in mvc and ef, so I have relied on a lot of tutorials.
I started with this one...
http://msdn.microsoft.com/en-us/data/gg699321.aspx
Everything else I find on the web pretty much just shows me the same things, so I figured this was pretty simple.
The stored procedure in question is pretty simple, it just returns a string from a table.
SELECT TOP 1 ConnectionString
FROM tConfig
WHERE Active = 1
I generated an edmx file, like in the article above, and it generated the following code in a context file. I have tried this both with, and without the EntityContainerName next to the procedure.
public virtual ObjectResult<string> psMasterDataSource()
{
return ((IObjectContextAdapter)this).ObjectContext.ExecuteFunction<string>("CentralApp.psMasterDataSource");
}
Where I am using it is also pretty simple.
public string GetMasterDSConn() {
var context = new CentralApp();
var conn = context.psMasterDataSource().SingleOrDefault();
return conn;
}
But when I run it, I get the following error.
The FunctionImport 'psMasterDataSource' could not be found in the container 'CentralApp'.
I saw someone on another site talked about editing the XML, but I couldn't find anything helpful on what to edit. So I am hoping I am missing something simple there.
I appreciate any help on this. I am ready to get this app tested, but this is holding me back.
I have an odd situation with a user control in VS 2010. The form designer keeps changing my entry and then telling me it does not exist! It compiles and runs the first time, and then if I change something unrelated, it gives me an error in the designer.cs file (Cannot resolve symbol SomeEntry).
private SomeEntry someEntry;
// ...
this.someEntry = new **MyNameSpace**.SomeEntry();
if I remove the MyNameSpace.
this.someEntry = new SomeEntry();
it works, until I make a change again. If I look at the class when the mouse is over the changed designer file, SomeEntry shows SomeEntry.SomeEntry()
instead of MyNameSpace.SomeEntry()
Basically, the definition is something like this:
namespace MyNameSpace
{
public partial class SomeEntry : FormValidatingUserControl
{
public SomeEntry()
{
InitializeComponent();
}
}
}
So, what do I do?
It turns out that I should have posted my code EXACTLY as it appeared, as I am sure someone would have figured this out for me sooner.
The issue was that I was trying to simplify for the post, and changed the names of MyNameSpace and SomeEntry to keep it generic.
The project is something the namespace is something (so far, normal) and there was a generated class something from the entity framework.
To reproduce the problem, I created a new project called WinFormTestX. So, the solution is WinFormTestX and the project WinFormTestX. I added a class called WinFormTestX, but did nothing with it.
namespace WinFormTestX
{
public class WinFormTestX
{
public int ID { get; set; }
}
}
Now, I create a UserControl (UserControl1) and drop a simple button on it. Compile it, and the toolbox adds this control, as expected. Now, I drop it on Form1 and compile it and get an error:
Error 1 The type name 'UserControl1'
does not exist in the type
'WinFormTestX.WinFormTestX' D:\Data\Projects\Temp\WinFormTestX\Form1.Designer.cs 31 51 WinFormTestX
As soon as I right click on the class WinFormTestX and Exclude From Project (or delete it), everything works.
So, just having the class in the project of the same name as the namespace, even when it is not used, causes an issue. Obviously, now that I know the cause, there is a simple way around this. But, is this something that is a "bug" that should be submitted to Microsoft?
I've had stuff like this happen when manually moving a class into a new namespace. If you're not careful, your class can become defined multiple times. For example, there may be a residual designer .cs file that still defines the class in its old namespace or some other .cs/.designer.cs mismatch. In other words, your assembly may contain both a SomeEntry.SomeEntry and MyNameSpace.SomeEntry class.
Check the Visual Studio object browser to see if you have SomeEntry defined in multiple namespaces.
In my persistence layer, I've declared a load of Enums to represent tables containing reference data (i.e. data never changes).
In Linq2SQL, I am able to set the type of an entity property to an enum type and all is well, but as soon as I set a second entity's property to use the same enum type, the Code Generator (MSLinqToSQLGenerator) start generating an empty code file.
I assume that MSLinqToSQLGenerator is quietly crashing. The question is why, and are there any work-arounds? Anyone else experienced this problem?
Is your enum by any chance in a file named the same as the dbml? There is a bug in 3.5 (fixed in 4.0) where conflicts cause an empty file. Oddly, usually moving the using directives (and right-click; run custom tool) fixes it.
So if you have "foo.dbml" and your own "foo.cs" (in the same folder) with:
using System;
namespace MyNamespace {
}
it will break (generate an empty foo.designer.cs). If you have:
namespace MyNamespace {
using System;
}
it will work. I'm not kidding. Likewise, renaming "foo.cs" to "bar.cs" (and right-click, run custom tool) will fix it.
Oddly, I've discovered that this behavior only occured with an Enum named "GrantType". As soon as changed the name of the enum, the generator started working again.
