I’m deploying to a location on my C: drive, and I have the option for the application to check for upgrades turned off.

The deployment variable, isFirstRun, is always false for me, when it should — apparently — be true.

My steps

1. Add the following code:

2. Build and publish the application via ClickOne

3. Run the application

4. See the install of the newer version of the application

5. Never see the Message Box.

Now, it’s my understanding of isFirstRun is that it should be true the first time a new version of the app is run/installed. I’m not seeing it.

I’ve posted this online on a Microsoft forum, but, so far, no answers.

ComboBox-Filtered DataGrid

Wondering how to filter a bound WPF DataGrid or ListView/GridView by via a ComboBox?

It’s easy enough to bind data from a database table into either a DataGrid or GridView. It’s actually easy to filter a grid of data by a combobox based on a lookup table as well — it’s just hard to find examples!

What follows is a tutorial on how to filter via a combobox a table bound to a DataGrid or GridView inside a ListView.

Requirements

1. Visual Studio 2010 C# Express
2. Northwind sample database, Compact Edition 3.5
3. Two data tables connected via a relation, such as the Northwind Categories table’s relation to the Products table

Setup

1. Create a new WPF application in Visual Studio 2010 C# Express
2. Add an “Existing Item” to the project, changing the browse window filter to data
3. Browse to “C:\Program Files (x86)\Microsoft SQL Server Compact Edition\v3.5\Samples” or wherever the Northwind database can be found on your system
4. Select the ‘DataSet’ database model and all tables

ComboBox-Filtered List Grid

Creating ComboBox and Grid

1. Open the Toolbox window and drag a combobox onto the XAML Designer
2. Open the Data Sources window and drag the Categories node to the XAML Designer and drop it into the ComboBox
3. Open the Products node under the Categories node in the Data Sources window and set all its children to “None” instead of a control, except for Product ID, Supplier ID, Category ID, Product Name, and Unit Price
4. Drag the Products node (make sure it’s set to a DataGrid or a List, depending on what grid you want) under the Categories node in the Data Sources window and drop it onto the XAML Designer under the ComboBox
5. Optionally, add elements to the XAML Designer, like a label for the ComboBox
6. Optionally, style the grid

As part of my learning curve, I’m making some simple tutorials on the basics of data binding with XAML and WPF. For these tutorials, and for my own educational purposes, I do as much as I can within XAML. I’m saving study of model-view philosophies for later.

For these WPF-XAML tutorials, I’m using the Northwind database and CollectionViewSource as the source of data for the binding.

I hope you find these tutorials useful.

Use the Related Entries plugin as widget within a widgetized area such as your sidebar.

When a single post is displayed, the plugin will display other entries that share the same category with your post. The plugin displays the related entries by type, so all related links are in one section, all related podcasts in another section. If no related entries are found, nothing is displayed.

Partial Linkblog Settings

Partial Linkblog is a simple widget to add to your b2evolution theme.

Partial Linkblog screenshot

If you have a linkblog in your sidebar, you can add this widget to control what categories appear where in the sidebar. For instance, you can show the category name and link list for categories 4, 5, and 6 with one instance of this widget, followed by a completely different widget, and then finish with another instance of this widget showing category three and its link and description.

Install simply by copying the one file into your b2evolution plugin folder. Then visit your widget settings and add instances of the widget where you want them.

I elected to use Apache’s mod_rewrite. When you read in a multitude of sites that mod_rewrite can be tricky, believe it!

So, to redirect my main domain, softwarefemme.com, to a subdirectory index.php, but yet keep the parked domain, www.thewildlifeporch.com, directed to the main index.php:

(make sure to replace my domains with yours!)

# FOR GENERAL REWRITING

Options +FollowSymlinks
Options -Indexes
RewriteEngine on

# REDIRECT SWF

RewriteCond %{HTTP_HOST} ^softwarefemme\.com$ [NC]
RewriteRule ^$ wpswf/index.php [L]

# REQUIRED FOR TWP CLEAN URLS

RewriteCond %{HTTP_HOST} thewildlifeporch\.com$ [NC]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^  ./index.php
