1) VB Allows non-type template parameters
2) VB supports explicit specialization
3) VB allows the type parameters to be used as the base class for the generic type
4) VB allows a generic type parameter itself to to be a generic
5) VB enforces that all codes are valid for all types of parametrs what would be the Best Choice ?
<ItemsControl DockPanel.Dock="Top" ItemsSource="{Binding Path={x:Static vmc:clsPersonViewModel.ChildrenPath}, Mode=OneWay}">
<ItemsControl.ItemTemplate>

In the code above, if there are no children (the ChildrenPath property returns NULL), nothing is rendered in the view. In the code below, when ChildrenDataSetPath is NULL the XamDataGrid still gets rendered. How do I achieve the same for a single object (as opposed to a collection) as the datacontext?
<DataTemplate DataType="{x:Type vmb:clsPersonViewModel}">
<igDP:XamDataGrid DataSource="{Binding Path={x:Static vmb:clsPersonViewModel.ChildrenDataSetPath}}">

In VB.NET,I want to create template at runtime and save it the template with name. for ex : Administrator design a page with 5 fields like using firstname, lastname, dob,nationality and job. He want to assign this page to the user with some restriction like user1 need to enter the all the fields and save it the forms as user1profile, but user2 need to enter only firstname and lastname and save it as user2profile.(in features, he can remove the fields from the form).

How can I do this?
I'm working on my first T4 code generation tool to add some Stored Procedure helper code to my project. I've created custom types (e.g. StoredProcedure and StoredProcedureParameter to help with my code generation and have included the assembly and namespace references in my code:
<#@ template debug="false" hostspecific="false" language="VB" #>
<#@ output extension=".generated.vb" #>
<#@ assembly name="$(TargetPath)" #>
<#@ import namespace="StoredProcCodeGenerator" #>
This allows me to use my custom types in my T4 template code. However, because my custom types exist in the same project as the T4 template code, I can't recompile my project once I run the template code without restarting Visual Studio. This isn't very much fun.
I read a great article that addresses this exact issue by using the T4 Toolbox, but it's not working. Either I'm implementing the VolatileAssembly directive wrong or the T4 toolbox simply didn't get installed. I'm not sure that the toolbox got installed correctly (I'm using VS 2010 on Win XP).

I should be able to get result back as long as there's a match in the parameters.

Basically Commands has Parameters and parameters has functions like Add, AddWithValue, and etc. In all tutorials i've seen, i usually noticed that they are using Add instead of AddWithValue.

I have already got all the programing done, working great! But now it has got to the stage, that I need the program to print out invoices from the program. I have the program extract certain records from an attached database, and will most probably pass them into a variable in the function.
NOW... I have a template of the tax invoice page setup in MS word. I was going to make a macro in word that will automatically fill in all the "static" information, but I was wondering if passing the variables from the main program into the word macro is: 1. possible and 2. the best way of doing this.
I am still a noob when it comes to VB so please excuse the next question, but is there a way to set up a page to be printed including tables, logo, different font styles.. etc within the VB program?

View 1 RepliesI am using Visual Studio 2008 Express, and I was wonder which Visual Studio Installed Template I should use just to execute VB code? Previously, I generated a project using Window Form template with a button to start, and it has references which made my .exe not to execute in any directory structure. Someone indicated that it must not have other absolute references and I think this was using absolute references? All I need to is to execute VB Code. What template would you suggest? Where do I put the start of the VB program to execute at? Since I don't need a form, there is no on event for me?
