Often when I take a look at sample code there are a lot of regions. I need to open them all the time, it really start to make me crazy. Why does people even use Region in their code, what's the point of hiding code? I think it's only an excuse to hide code because of a too large file. What do you think? Read More...

My actual problem is to develop a image (object) carousel. There are a lot of details to take care about. One of them is to create images dynamically with a great UI like border or shadow. First I startet up to write code like: Dim brd As New Border brd.Height = 130 'Bildhöhe+ 30 für text brd.Background = New SolidColorBrush(Colors.LightGray) brd.CornerRadius = New CornerRadius(3) brd.BorderThickness = New Thickness(3) Dim grdcoll As New GradientStopCollection() Dim grdstop As New GradientStop grdstop.Offset = 0 grdstop.Color = Colors.LightGray grdcoll.Add(grdstop) .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;...

I just found out something really weird about HTML comments. Apparently, according to standards, you can't do this: <!-- comment ------------------------ --> That is, you can't put two or more ‘-‘s inside a comment. It works as expected in IE7, but it breaks down horribly in FireFox. FireFox simply renders the comment to the user, which is pretty useless as that's not what comment are for!!. The standards "recommend" developers to not put two or more consecutive ‘-‘s inside an html comment. Now, that's weird. If there are specific delimeters like <!-- and -->, then I should be able to use any part of those delims (but not the whole) inside a comment, shouldn't I? Since, we're in the vicinity of comments...

Note to self, and anyone else who cares... ViewState("ReferrerURL") is not the same as ViewState("ReferrerUrl"). Same with Cache object names. Apparently VB does *kinda* care about case sensitivity... Read More...

Recently, I was developing a pretty sophisticated Crystal Report that included multiple sub-reports and used multiple stored procedures as data sources. All of those stored procedures accepted the same parameter, which made my life a little easier, since I only had to deal with one parameter that I needed to pass to my Crystal Report. In order for all sub-reports to be able to recognize the parameter, which I am passing to the main report, I had to link all of my sub-reports to the main report using that parameter. In order to link a sub-report to the main report, the following actions should be performed: To link a subreport to the data in the primary report If you are creating a new subreport or importing an existing report as a subreport...

Some time back on the form somebody was looking for some help in searching URL within text and make those URLs as link. Me and that guy tried various regex but the one that worked out I thought to put it on the blog so that it can help me and others later. Regex itself is: -------- In VB.Net --------- Dim regx As New Regex(" http://([\w+?\.\w+])+([a-zA-Z0-9\~\!\@\#\$\%\^\&amp;\*\(\)_\-\=\+\\\/\?\.\:\;\'\ ,]*)?", RegexOptions.IgnoreCase) -------- In C#.Net --------- Regex regx = new Regex(" http://([\\w+?\\.\\w+])+([a-zA-Z0-9\\~\\!\\@\\#\\$\\%\\^\\&amp;\\*\\(\\)_\\-\\=\\+\\\\\\/\\?\\.\\:\\;\\'\\ ,]*)?", RegexOptions.IgnoreCase); And I used following method to convert the URLs into link within text. -------...
