im new to vb.net 2003 but have used vb 6 for years and dabbled with 2005. A program that would usually take me a few hours to make i am on day 5, 4 and a half of which have been trying different ways to get it to update, and not one of them will post the information back to the SQL 2000 database I am actually going insaine.
The best i can get out of it is this error. "Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information" I have googled it and come up with the fact the primary key isnt set right, but i still cant get that to work. Here is the peices of code that are relevant.

End Sub
It giving the following error. Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information. Can there is another way to update the access database by using datagrid view.

I have a container with different controls in it. This container can be shown 1 or more timeson a form. The number of times is not known when the application is build.So form with the number of containers must be generated by code. When the number of containers is high a scroll bar must be shown.My idea was to use the control TableLayoutPanel. The first row consists of the container with it's controls. When loading the form a number is calculated. This number is used to show the number of containers.

I use Visual Basic 2010 Express. I want to create a WinForm app in which there are several buttons "table1", "table2"... Each button must display the corresponding table of a database in a specified region of the same form.
I'm able to link a MS Access database (.accdb) file to the app. But, how do I create that dynamic area whose content would be one of the database tables of the linked database? I tried using DataGridView, but I'm a newbie and I'm missing something; it doesn't work.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

i need to create sql tables based on user needs lets say a guy needs a table of 4 rows 5 columns other user needs 3 rows 3 columns each with different types so how is the best way for letting them choose like they write in a text box ( this will be the value of rows)4 and another text bvox the count of columns and i have those 2( rows and columns needed) numbers i create the table as is.based on those. by default i create type as varchar max then later on we must fill the table using datagrid.

In .net, it's possible to use generics so that a function can accept arguments which support one or more interfaces and derive from a base type, even if there does not exist any single type from which all valid argument types derive. For example, one could say: Sub Foo(Of T As {IInterface1, IInterface2, SomeBaseType})(Param as T) And be allowed to pass any derivative of SomeBaseType which implements both IInterface1 and IInterface2. This will work even if SomeBaseType does not support Interface1 and Interface2, and classes which do implement those interfaces don't share any common ancestor that also implements them. This can be very convenient if one won't need to keep the parameter anywhere after the function has exited. Unfortunately, I can't figure out a way to persist the passed-in parameter in such a way that it can later be passed to a similar function, except perhaps by using Reflection. Is there any nice way of doing that?
The closest I've been able to come up with is to define an interface INest (perhaps not the best name-- thus:
Interface INest(Of Out T)
Function Nest() As T
End Interface
And for any interface that will be used in combination with others or with base-class "constraint", define a generic version as illustrated below:
Interface IFun1
' Any members of the interface go here, e.g. ...'
Sub DoFun1()
[CODE]...
A class which will support multiple interfaces should declare itself as implementing the generic ones, with itself as the type argument.
Class test123a
Inherits sampleBase
Implements IFun1(Of test123a), IFun2(Of test123a), IFun3(Of test123a)
End Class
If that is done, one can define a function argument or class variable that supports multiple constraints thusly: Dim SomeField as IFun1(Of IFun2(Of IFun3(Of sampleBase)))
And then assign to it any class derived from sampleBase, which implements those interfaces. SomeField will implement IFun1; SomeField.Nest will implement IFun2; SomeField.Nest.Nest will implement IFun3. Note that there's no requirement that IFun1, IFun2, IFun3, or sampleBase share any common derivation other than the generic interfaces inheriting from INest(Of T). Note also that, no matter how many INest-derived interfaces a class implements, it only needs to define one implementation of INest(Of T).Nest. Not exactly beautiful, but there are two nice things about it: (1) any concrete class which in fact implements the necessary interfaces can be assigned directly to a field declared as above, without a typecast; (2) while fields which chain the types in a different order are not assignment compatible, they may be typecast to each other. Is there any better way to store something in such a way that it's "known" to support multiple interfaces and derive from a certain base type? Given that one can write such code in a type-safe manner, it would seem like the .net 2.0 CLR could probably support such a thing quite nicely if compilers offered a little assistance.

I was looking through some legacy code we have and I noticed something that struck me as particularly odd.Say we have the concrete class TestClass. TestClass implements the interface ITestClass.What sort of behavior should I expect in the following case, then? (I didn't realize this was even possible)
Dim testClass as TestClass = Nothing
Try
testClass = New ITestClass

Error Message: "This server version is not supported. Only servers up to Microsoft SQL 2005 are supported VB.NET" I am using VB.NET 2008 and attempting to connect to SQL Server 2008 with XP as the operating system. I have service pack 1 installed in Visual Studio but this error message presists. The articles I have read on this error said to install sp1 as a solution but I have done that and the error persists. FYI, the error does not occur when I am using code to connect to SQL Server but when I attempt to connect using one of the designer wizards this error occure.

how to create a local database, create some tables and set relations between those tables (just like in access) and I can show, add, edit and delete that data from a form.
but what I have yet to figure out is if I have 2 tables (i.e: tbleName, tblFood) and I want to have multiple tblFood items show for every 1 tblName item.
I've found that if I add a txtbox of the name table and a datagrid of the food table, the datagrid view shows all the food records, not just the ones for the name txtbox.
