With LINQ, and using C# (I don’t know VB much these days): bool b = listOfStrings.Any(s=>myString.Contains(s)); or (shorter and more efficient, but arguably less clear): bool b = listOfStrings.Any(myString.Contains); If you were testing equality, it would be worth looking at HashSet etc, but this won’t help with partial matches unless you split it into fragments … Read more
Two significant differences: Lookup is immutable. Yay 🙂 (At least, I believe the concrete Lookup class is immutable, and the ILookup interface doesn’t provide any mutating members. There could be other mutable implementations, of course.) When you lookup a key which isn’t present in a lookup, you get an empty sequence back instead of a … Read more
Please use HSTS (HTTP Strict Transport Security) from http://www.hanselman.com/blog/HowToEnableHTTPStrictTransportSecurityHSTSInIIS7.aspx <?xml version=”1.0″ encoding=”UTF-8″?> <configuration> <system.webServer> <rewrite> <rules> <rule name=”HTTP to HTTPS redirect” stopProcessing=”true”> <match url=”(.*)” /> <conditions> <add input=”{HTTPS}” pattern=”off” ignoreCase=”true” /> </conditions> <action type=”Redirect” url=”https://{HTTP_HOST}/{R:1}” redirectType=”Permanent” /> </rule> </rules> <outboundRules> <rule name=”Add Strict-Transport-Security when HTTPS” enabled=”true”> <match serverVariable=”RESPONSE_Strict_Transport_Security” pattern=”.*” /> <conditions> <add input=”{HTTPS}” pattern=”on” ignoreCase=”true” … Read more
No, that’s the correct way to do it. This worked exactly as it should, something you can work from perhaps: using System; class Program { static void Main(string[] args) { System.AppDomain.CurrentDomain.UnhandledException += UnhandledExceptionTrapper; throw new Exception(“Kaboom”); } static void UnhandledExceptionTrapper(object sender, UnhandledExceptionEventArgs e) { Console.WriteLine(e.ExceptionObject.ToString()); Console.WriteLine(“Press Enter to continue”); Console.ReadLine(); Environment.Exit(1); } } Do keep … Read more
For logging purposes, I’m afraid there’s no nicer way of doing this but to construct the string yourself: string query = cmd.CommandText; foreach (SqlParameter p in cmd.Parameters) { query = query.Replace(p.ParameterName, p.Value.ToString()); }
Off the top of my head: Array* – represents an old-school memory array – kind of like a alias for a normal type[] array. Can enumerate. Can’t grow automatically. I would assume very fast insert and retrival speed. ArrayList – automatically growing array. Adds more overhead. Can enum., probably slower than a normal array but … Read more
Use a foreach loop instead of a for loop – it solved my problem. int j = 0; foreach (Microsoft.Office.Interop.Word.Page p in pane.Pages) { var bits = p.EnhMetaFileBits; var target = path1 +j.ToString()+ “_image.doc”; try { using (var ms = new MemoryStream((byte[])(bits))) { var image = System.Drawing.Image.FromStream(ms); var pngTarget = Path.ChangeExtension(target, “png”); image.Save(pngTarget, System.Drawing.Imaging.ImageFormat.Png); } … Read more
Somewhere in that mess, the non-breaking spaces from the HTML template (the  s) are encoding as ISO-8859-1 so that they show up incorrectly as an “” character That’d be encoding to UTF-8 then, not ISO-8859-1. The non-breaking space character is byte 0xA0 in ISO-8859-1; when encoded to UTF-8 it’d be 0xC2,0xA0, which, if you (incorrectly) … Read more
The And operator evaluates both sides, where AndAlso evaluates the right side if and only if the left side is true. An example: If mystring IsNot Nothing And mystring.Contains(“Foo”) Then ‘ bla bla End If The above throws an exception if mystring = Nothing If mystring IsNot Nothing AndAlso mystring.Contains(“Foo”) Then ‘ bla bla End … Read more
System.Threading.Thread.Sleep(50); Remember though, that doing this in the main GUI thread will block your GUI from updating (it will feel “sluggish”) Just remove the ; to make it work for VB.net as well.
