• Visual C# "OUT of Memory" String construtor

  Hi, im getting a "out of memory" exception when I try to pass a large char array in the the string construtor. The array has a length of about 200MB, its XML Data. I need to convert this to a string for the further handling. For smaller data stuff works fine. Any ideas how to convert the data to a string Thanks Dob It is ofcourse possible to use a XmlDocument, but keep in mind that it parses the entire document and creates a document object model in (cached) memory. You could call this streaming but it consumes the stream in a single method call. The size of this model wil be far over 200 MB (it doesn't just store de data itself but also creates a class structure around it) and can really hamper the performance of your app ...Show All

• Visual Studio Express Editions How to make the registry settings effective without restarting the system

  I have developed a program to disable the USB Read and Write access with the help of registry. But every change requires a Restart which is not feasible in my case. Is there any feature or process, which resolve this issue, that is, to make the modification in registry effective without restarting the system. The solution is required in VB.NET. If your operation in registry is under HKEY_CURRENT_USER\Software\VB and VBA Program Settings, you can use the GetSetting and SaveSetting functions provided by NB.NET. To access the registry without the constraints of the GetSetting and SaveSetting functions, use the Registry and RegistryKey classes in the Microsoft.Win32 namespace. The Registry class supplies the base registry keys to ...Show All

• .NET Development Is this a bug , any one can tell me?

  I found a bug when I am programing: when I use like this: " ".IndexOf(" ") is returns -1,when it should return 9; but " ".IndexOf(' ') is OK. and belows all worked well: " ".IndexOf(" "); " ".IndexOf(" "); " ".IndexOf(" "); My environment is : Windows XP SP2(English Edition + Mutil-Language Pack) + .NET Framework v2.0.50727+Visual Studio 2005 PS: It works well in javascript. Note that the above ONLY applies to the BCL-provided System.String.IndexOf; if you use the System.Char overload provided in the globalization namespace (System.Globalization.CompareInfo.IndexOf) then you get the right behavior, always. Proof that those BCL "shortcuts" sometimes forget to tag secon ...Show All

• Visual C# foreach where

  Is there anyway to specify the types of items to get when you iterate through a collection with foreach. Right now you have to do like this foreach ( UIElement b in maincanvas.Children) { if (b is Bomb ) (b as Bomb ).Move(); } Another way is this: foreach ( Bomb b in maincanvas.Children) { if (b ! = null ) b .Move(); } I think both ways are very inconvenient, I want to do something like this. Just like when you specify generic objects: foreach ( Bomb b in maincanvas.Children where b : Bomb ) b .Move(); Is there any similar syntax that does what the above snippet do I know the snippe ...Show All
