What's the quickest/neatest way to calculate the next anniversary of someone's birthday. For example, if I knew a person was born on 31st January, 1990, and today is the 10th February 2000, their next anniversary will be 31st January, 2001. February 29th should roll onto March 1st (e.g. if they were born on February 29th 1990, their fi...

I am attempting to insert a mass of records into SQL Server 2005 from Vb.Net. Although the insertion is working fine, I am doing my best to try to make it as fast as possible. Currently, it takes ~ 11 mins for 100,000 records. What would be the suggested approach to inserting a large number of records into SQL Server from an Applicati...

I have a custom DataGridView column that uses an embedded control that pops up a search window for the value of that column. The important thing is that the databound column is a numeric ID, but the custom column cells display a text description. How do I get the column to sort on the text description rather than the numeric ID? I...
Are there any 'good' resources for porting a VB.NET winforms application to C#? I'm sure there are is software that just translates the code, but I'm looking to refactor the code at the same time. Keeping it in its current form is problematic, since it uses some of the 'bad design' practices that VB.NET allows, and would further compli...
In an webservice I see this code: Whats the point of catch the exception and just throw it again? Do I miss something? <WebMethod()> _ Public Function dosomething() As Boolean Try If successful Then Return True Else Return False End If Catch ex As Exception Throw ex End...
I want to insert a new row into an Access database.

However...
I have created a mutli-column combobox in VB.net 2008 using windows forms 2.0. I am having trouble accessing data once selected to use in the remainder of the form. There does not seem to be a selected event to use in conjunction with the winform 2.0 combobox. Does anyone have any experience using winforms 2.0? Also I guess a better que...
I am trying to make a small, data-driven widget that is populated with data from a database on the fly. I can load it initially just fine, but when the index of an ASP DropDownMenu is changed, the widget returns a 404. This could be a symptom of how I am using the Javascript, or how I am using the ASP. I honestly don't know for sure. ...

When answering another question I started to wonder how I could Add new properties to all controls in a form just like the ToolTip-control does. For example I could use that to Add a "IsDirty"-flag to all textboxes just by adding the component to the form and it would handle this for every textbox. When adding the tooltip-control to th...
I'm coming from a C# background and I really like the type inference that C# 3.0 has. I'm trying to do similar things in VB.NET (some of which appear possible), but in some cases the compiler seems to be not nearly as good at inferring the type. For example, I have a method that returns an object of type System.Guid. In C# I'd do thi...
I'm trying to find an zip compression and encryption component with encryption suitable for use by the US Federal Government, so I can't use Zip 2.0 encryption, it has to be AES or the like. I've already found SharpZipLib (can't do AES encyrption), and Chilkat (can do AES encryption, but costs money). Am I missing any other options? ...
I have this C# extension method that will extend any dictionary where the Value type is an IList. When I write the equivalent code in VB.Net I get the following compile error: "Extension method 'Add' has some type constraints that can never be satisfied". I find this really puzzling as the same type constraints can be satisfied in...
