Filling SQL View In Typed Dataset Clientside
Mar 22, 2010
I recently updated an app that I wrote to allow the clients to run the app in read only mode disconnected from the database by serializing the typed dataset, and when they are offsite/offline instead of connecting to the database the serialized dataset is loaded. This has been working great and then I hit a major snag.
A majority of the graphs and reports are based on sql views that are typed views in the dataset. Of course offlline the tableadapters cannot run the sql views.
Does anyone know a way to run/fill the view with the already loaded dataset? I can add rows clientside so I'm inclined to believe there must be some way to fill the view clientside but I've been at this for a number of hours now and not making any real progress.

I am designing a form to Enter new City Name list where i accept following fields
CityName, District, State, Country, Pin.
because a State names and Country names can be retrived from earlier entries, i want to allow user to select desired name from a list in combo box or a list in Auto Complete Custom Source for text box, to do this i have added a Table Adapter to underlying DataSet having Query "SELECT DISTICT STATE FROM CITY ORDER BY STATE".
Now, how do i use this Table Adapter to fill the ComboBox List without binding
And also Custom Source List for TextBox.

I am having difficulties with Filling a dataset. It seems to be automatically assigning a datatype to the column based off of the first field of data it finds in that column. The column sometimes contains an integer, but it may also contain letters and numbers. If the first field is an integer, it says the fields in the column that contain a letter are DBNull. I'd like for the entire dataset to be formatted as a string/text type since I do not know what the values will be that I'm importing 100% of the time. How do I tell the dataset to expect a certain datatype for all columns and rows i'm going to import?

I'm starting to learn ASP.NET MVC and since I work in a VB.NET shop I'm converting an example from C#. I'm trying to implement a strongly typed view and the example I'm looking at shows the following:
<tr>
<td>Name:</td>
<td><%=Html.TextBox(x => x.Name)%></td>
</tr>
I've come up with the following in VB.NET:
<tr>
<td>Name:</td>
<td><%=Html.TextBox((Function(x As Contact) x.Name).ToString)%></td>
</tr>
Is this conversion correct? This seems really cumbersome (I know, I know, VB.NET is more cumbersome than C#, but I have no choice in the matter).

I created a dataset in Visual Studio 2010 containing two tables: tblCategories and tblAnswers. tblCategories has two columns: CategoryNumber (AutoNumber and primary key) and CategoryName. tblAnswers has three columns: AnswerNumber (AutoNumber and primary key), Answer, and CategoryNumber. The CategoryNumber columns in each table are related. I have a command button which I want to use to add a record to the CategoryName column in tblCategories with the data typed in a textbox. When I try to access the dataset to add a new row(dataset.tblCategoriesDataTable.NewRow), the NewRow method isn't present. I've done some reading which suggests that I need a TableAdapter, but it seems like that is for connecting to an external file because I have to select a connection. I have no external SQL files or database. I want the user to be able to create a database within my program.

I've got a typed dataset. I bind the data with a binding source to a form with arround 200 textboxes, dataedits and so on. Everything works fine with one exception:In my database I have empty DateTimes (DBNull.Value). And when they get bound to a DateEdit-Control, I get the following exceptions:
A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll
A first chance exception of type 'System.Data.StrongTypingException' occurred in myTestDLL.dll
I tried to change the NullValue-Property in the DataSet-Desinger to something else as 'Throw Exception', but it doesn't work for a DateTime. For other types like Integer or String it works fine.I dont know a nice solution (right now I fill the empty dates with some dummy date and make it invisible in the DateEdit-Control, but this is very uncool) and I hope to find some help here.

I am using the ASP.NET MVC VB.NET XML Literals View Engine created by Dmitry Robsman and described on his blog in this post.
[URL]
I would like to create strongly typed view pages using this view engine, but it doesn't seem to contain the requisite VbView(Of TModel) generic type by which I would create such a view class.
The end result should look something like this:
Namespace Views.Client
Public Class Details(Of Models.Client)
Inherits SiteMaster
[Code]....
Once there is a VbView(Of TModel) class that inherits from Dmitry's VbView class, how to hook that up so that it works with standard MVC controllers that call the view like this.
Function Details(ByVal id As Integer) As ActionResult
Dim c = SomeGetClientFunction(id)
Return View(c)
End Function

Firstly here's the code and i will explain my problem underneath. [code...]
Now as you can see I have a variable that holds a value member of the combo box Products which is the productID of the current product selected. Then it searchers through the products datatable and once its found the correct product or not it stores the answer in slectedproductrow. next I test to see if selected product row has found the product if it has i then see if the product has already been added to the order by seraching the the customer current order datatable if it hasn't it adds the current information to the order by using selected product row.
Now the problem i get is when i add the same product it still adds the information again as currentorderrow comes back as nothing everytime even if the product has been added before but if it was in the table which it should be it should skip that bit and just go to add the current qtys toghther.Also if i go to add a diffrent product it overwrites the the other one. So i can't store the customer order. Its like i can't store more than one row. By the way I have a datagrid and can see the product get over wrriten.

I am trying to fill a combo box using a dataset and data adapt. I am struggling too work out how to do it. I thought it would have been easy but I was wrong. i can set the text to read the first line of the colomn but nothing else. I was wondering if anyone could help me out with what I have to do. I think I have to increment inc and add a line underneath but I don't know how to do that
comboMaps.Text = datSet.Tables("TheLastShot").Rows(inc).Item("Maps")

ok normally when i fill data i do it this way adapter.Fill(dataset, "table1") However instead of using Strings, i prefer using enums so for example i have:
public enum Tables
T1
T2
end Enum
but since adapter.fill does not provide an "integer" argument when i add i had to convert it to a string as such adapter.Fill(dataset, cstr(Tables.T1)). i find this "dirty" and was wondering if there is a better fix

I cannot figure out for the life of me why I cannot reference a dataset table using the strongly typed name. I created a "news" table in a dataset to write out and read in a simple xml.
If you look at the code below this does not work: 'Dim TableFail As ADataSet.NewsDataTable = ds.NewsDataTable 'Does not work
I can access the table by using an untyped name however: Dim NewsTable As ADataSet.NewsDataTable = ds.Tables("News") What is the proper way of accessing the datasets 'typed' datatables name.

Any resemblance to your code is purely coincidental.
