C#: Use exit code from application in Windows batch file (script)

Marek Śliwiński — Thu, 21 Jan 2010 13:58:03 +0000

That’s pretty easy stuff if you know it already. Take a look on example (TestApp.exe): static int Main(string[] args) { int myCodeNumber = 1; // Return [...]

C#: Reading embedded XML file

Marek Śliwiński — Thu, 26 Nov 2009 12:04:01 +0000

Snippet: Assembly assembly = Assembly.GetExecutingAssembly(); string filePath = assembly.GetName().Name + ".filename.xml"; using (Stream stream = assembly.GetManifestResourceStream(filePath)) { if (stream != null) { // do something with Stream from file } }

Transact-SQL: Compare strings in SQL and spaces

Marek Śliwiński — Thu, 12 Nov 2009 12:00:50 +0000

Just a quick reminder/note. What will be the result for below string comparision? What do you think? IF (' ' <> '') print 'different' ELSE print 'equal' If you answered ‘different’ then you are wrong :) The result will be ‘equal’. Why? Because SQL ignores trailing spaces when comparing strings.

C#: WinForms – Send POST,GET HTTP data and retrieve webpage source using WebClient with cookies or HttpWebRequest,HttpWebResponse. Phpbb.com login example.

WebClient class is very handy and useful but has one big gap. There is no build in cookies handling between requests. Luckily somebody wrote briliant solution for this :) http://couldbedone.blogspot.com/2007/08/webclient-handling-cookies.html With above snippet the WebClient class will be enough for most common web tasks. Below you find my rich (maybe to rich) commented example of use WebClient class [...]

C#: Get all inner exceptions messages

Marek Śliwiński — Fri, 16 Oct 2009 20:22:06 +0000

Very often InnerException of Exception has some valuable details what happens. Quite often InnerException has an InnerException so more error messages to investigate. Theoretically there can be unlimited number of Inner Exceptions so below are 2 small snippets to get all messages from them. Both snippets do the same but first in a “while method”, second [...]

C#: Language not supported in Ajax Control Toolkit? No problem, do localization by yourself

Marek Śliwiński — Wed, 30 Sep 2009 06:01:45 +0000

In my projects I often have to implement user interface in two languages: English and Polish. Although localization in .NET is quite easy, one thing was annoying to me: AjaxControlToolkit doesn’t support Polish language. When my user choose Polish language on the webpage then he still see in Calendar control ‘Today’ word instead Polish version (‘Dzisiaj’). [...]

Regular Expressions: Count the occurences of characters set/group in a string

Marek Śliwiński — Thu, 24 Sep 2009 07:15:42 +0000

Let’s say, you would like to count the number of characters group, for example: all upper case chars in string. How to do it? That’s easy by regular expressions. Pattern for all upper case chars will be just: [A-Z] So here is a code: string text = "Hmm, how to count ALL UpperCase chars?"; int result = Regex.Matches(text, [...]

Visual Studio: Automatically increment assembly build version with custom settings (add-in)

Marek Śliwiński — Mon, 21 Sep 2009 16:25:45 +0000

I always wanted to have automatic build version increment for my apps and libraries to avoid setting it manually again and again. Additionally there should be support inside Visual Studio and possibility for custom settings because I like the “date signing” where 3 last fields are just YYYY-MM-DD. A dream come true ;) in form of [...]

Visual Studio: DevExpress menu not visible after CodeRush Xpress installation

Marek Śliwiński — Thu, 17 Sep 2009 08:46:42 +0000

DevExpress company has a lot of free goodies for .NET developers. Unfortunately Microsoft has asked them to hide DevExpress entry from main menu (only in case of DevExpress freeware tools, for example CodeRush Xpress or DXCore). That’s very annoying behaviour because most of the DXCore community plugins can be accessed from DevExpress menu. To show DevExpress [...]
