If you receive an error resulting from a missing Microsoft.VisualBasic 2.0.0.1 file when attempting to run a project from the Chapter01 folder or other early chapter folders, do the following:

1. Right-click the project entry in Solution Explorer and choose Properties to open the tabbed Properties window.

2. Click the References tab.

3. If a Microsoft.VisualBasic item is present and its check box is marked in the Imported Namespaces list, clear the check box.

4. Build and run the project.

The next time you open the project, the item (a User Import for a Visual Basic 9.0 ["Orcas"] LINQ preview version) should be missing from the list.

See the message regarding the OleDBDataObjects.sln project for more details on this issue.

Sorry for the inconvenience,

Alternatively, you can use Notepad to replace
<ProductVersion>8.0.50727</ProductVersion>
with
<ProductVersion>8.0.50110</ProductVersion>
in the ProjectName.vbproj file

Here is my technique for fixing the error: Could not load file or assembly 'Microsoft.VisualBasic, Version=2.0.0.1, Culture=neutral, PublicKeyToken=6315780d5082271f' or one of its dependencies. The system cannot find the file specified.

I double-click My Project in Solution Explorer. Choose References. In the References list click System. Click Remove. Click Add. In the Add Reference dialog on the .Net tab choose System then clik OK. This correctly sets the VisualBasic reference to the assembly on my machine.

To set the connection to SQLEXPRESS I had to double-click Settings in Solution Explorer. Click the connect string under the Value column. Click the elipsis (...). Change the Server Name from LocalHost to .\SQLEXPRESS. Test the connections then click OK.

Thanks Roger for all the great training through the years!

Following DeveloperDan2's instructions, I've managed to fix the "Could not load file error...." when opening the main form in OrdersByCustomerV3 - Final but when i try to set the connection to SQLEXPRESS from Settings it tells me "This project does not contain a default settings file". Both version 1 and 2 of the OrdersByCustomers projects had a connection string that could be modified to ".\SQLEXPRESS". How do i set the connection string for SQLEXPRESS in OrdersByCustomerV3 - Final?

Thanks....
