• aferoce Regex group

  Hi I'm making a little test building a search application using regex and some other stuff. This is one of the groups in my regex pattern: ( <atta>\\d{4}) The problem is i dont want the value to be 4 only, i need it to be able to find it at that spot even if it is 8, 9 or 10 instead. After doing some reading i saw that there is something you can write like {4+} so that is can be atleast 4 or more. But can't get it working, Anyone can help me Hi, I'm not sure what you're trying to do... {4} is a quantifier, which means your group should match exactly four digitals. If you want t match 4-9 digits, use ( <atta>\\d{4,9}) . But.. How I understood you, you want to match&nbs ...Show All

• Boulderdude FileSystemWatcher Problem

  Hi, I am using FileSystemWatcher to copy sound files from a network path to my local path. I have 4 network paths configured and I start watching a network path in a new thread. Now, for 2 of my paths, I am having no difficulty in copying completed files. But for the other 2 paths, I am not able to distinguish when the file is completly written. The same code works for the first paths, by the way. The first 2 paths are on same machine, say A. The second 2 paths are on other machine, say B. The sound files created on A use some recorder ( i dont know the exact one, since i cant access the machine as a whole, but do have access to the network path, since it is shared for me ). The sound files created on B use some other recorder. Now, wha ...Show All

• David d48701 Connection.Timeout

  First, Thanks for any and all assistance. I have a .NET application written in C# and ASP.NET (VS 2005). The Database is SQL Server 2005. I have several SPs executed from the ASP pages and all seems to work well. However, I have one SP that supplies an error "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." The SP executes(in QueryAnalyzer) in 32 seconds. The ASP page is timing out. I have the connection String Connect Timeout = 1000 and the ASP Server.Timeout = 1000. I have also verified the Remote Procedure Call in SQL server is set = 600, seconds. I have tuned the SP to only read necessay rows (by date) ~600K for a month. I narrow the results from there to r ...Show All

• ralfkret Why doesn't System.Array have an indexer?

  I'm probably missing something here, because my all of my searches came up with nothing. It seems only natural for Array to have an indexer. But instead, we have to use Get/Set Value(). Why is that thrace wrote: Allow me to nag some more: why doesn't Array have an indexer that gets and sets an Object How many index parameters would it take, considering that it has to support everything from one dimensional to N-dimensional arrays Interesting idea.

• shyma Unmanaged to managed callback through wrapper: this works but is it good?

    I implemented callback in mixed mode the following way and it works fine but I wonder if this is the right way to do it. In particular, is this 100% safe I mean could there be some obscure GC/CLR "event" that would make it crash at some point, for instance should not I be using pin pointers It works this way: a delegate is declared in C# and used as argument to the setCallBack() function of a C++ .net wrapper. This function casts this pointer and use it to initialize the callBack pointer value in an unmanaged C++ class (it also keeps its value so the Wrapper can also call the callback). The C++ .net wrapper is shown below: public ref class WrapperClass { public : delegate int CallbackType(); ...Show All
