Welcome to Imar.Spaanjaars.Com

I added a short article on embedding images in assemblies for the Compact Framework. The same principles apply to the normal framework, so check it out if you want to know how to embed and retrieve images from your .NET assemblies.

Pocket PC applications, just like ordinary Windows applications, often use images for all kinds of purposes, like Toolbar buttons, backgrounds, or just to spice up the User Interface. If you want to be certain that the images you're going need are always present on the device, you can embed them in the assembly, so they are always available. This article will explore the steps you need to perform to embed the image in the assembly, and how to retrieve the image again at runtime.

Due to popular demand, I decided to create a few Howtos / tutorials describing the implementation of a hitcounter in ASP pages that tracks the number of visitors to your site.

If you have a live Web site on the World Wide Web, you may be interested in how many people are visiting your site. You can of course analyze the log files of your Web server but that information is usually difficult to read. The log files contain information for each and every request a visitor has made to your site, including resources like images, Flash movies and so on. This makes it near impossible to extract information about individual users. It would be a lot easier if you could count the number of individual users that have visited you since you started your site. It would also be useful if you could see the number of users that are currently browsing your site.

This article will show you how to accomplish these two tasks by storing the hit counters in Application variables and in a database using code in the global.asa file. The counters in the Application variables are used to display them on a page in your Web site; either as a counter so your visitors can see it as well, or somewhere on a page in your Admin section, so only you have access to them. By writing the counter to a database you can maintain its value even when you restart the Web server, while you still have a fast and scalable solution.

This article extends the ideas from two previous articles where the values of the counters were just stored in Application variables and in a text file.

There is also an ASP.NET version of this article available.

The disadvantage of this method is that this information is lost when you restart the Web server. Two subsequent articles will demonstrate how to store this information in a text file and in a database, so the value for the counter will be preserved when you restart your Web server.

I recently added articles to the ASP.NET, ASP and HTML categories of the Articles section of the site.

I am also working on a few short articles on how to create a hit counter in ASP on your site that remembers the number of hits even when you restart the webserver. They'll be published soon!

The articles have been published and can be found here:

Update!! 12-20-2003
There seems to be a problem with the code presented in this article. When you click the new and styled Browse button, the Browse for File dialog is opened, and when you select a file, both text boxes (the hidden and the fake field) are displayed with the file's full path and filename. However, when you click the submit button, the real (and hidden) file box gets cleared and the form will not submit. When you click the submit button again, the form will eventually submit, but because the file box is empty, your file will not be uploaded to the server. This problem has been discussed extensively on various forums on the web, including the one run by Wrox.

So far, I haven't been able to isolate the problem or come up with a solution. It looks like this problem is caused by some security mechanism in Internet Explorer. I haven't tested various versions of IE yet, but I am sure it doesn't run on IE 6, SP1 (well, it doesn't run on *my* IE 6, SP1 ;-) )

If you do find a browser that runs this code fine, please let me know.

When you are using Cascading Style Sheets (CSS) in your Web pages, it is likely that you want to change the appearance of your HTML buttons as well. After all, the dull looking gray buttons give your site a bit of an old fashioned look. Usually, changing the style is as easy as setting a style or a class attribute, like <input type="button" value="Send Form" style="background-color: red";> to give the button a red color. However, this won't work with the Browse button that is attached to an input box that allows a user to upload a file. This article will demonstrate a so

This snippets demonstrates how to check whether a user is logged in or not. The code also shows how you can extract the UserData from the Ticket that is retrieved from the User Identity.

Although you should try to make most of your database design decisions at design-time, it can sometimes be really handy to create a database from your ASP code. This article explains how to create a Microsoft Access database using ASP.
