I have been trying to find out how to bind data to a System.Windows.Forms.DomainUpDown() control. Currently I have only come up with: private void Init() { List<string> list = new List<string>(); list = get4000Strings(); //4000 items foreach (string item in list) { ...
I have a server application (singleton, simple .NET console application) that talks to a GlobalCache GC-100-12 for the purpose of routing IR commands. Various .NET WinForm clients on the local network connect to my server application and send ASCII commands to it. The server application queues these ASCII commands and then sends them to ...
I'd like to write a simple application which keeps track of its current memory usage, number of created objects etc. In C++ I'd normally override the new operator, but for obvious reasons I can't do this in C#. Is there any way to do this without using a profiler? ...
I'm trying to launch Cygwin version of ruby.exe from a .NET application, but I'm stuck. c:\>"c:\cygwin\bin\ruby.exe" c:\test\ruby.rb /usr/bin/ruby: no such file to load -- ubygems (LoadError) As you see Ruby can't locate libraries because it's looking some Linux style paths. Obviously when I run ruby.exe from .NET since it can't fin...

Hi, Using some extensions provided by .net, one can find groups of parenthesis by using something like this: ^(\w+)\(((?>[^()]+|\((?<D>)|\)(?<-D>))*(?(D)(?!)))\)(.*)$ This will match the following: Func(innerfunction(arg)).DoSomething() With the following groups: Group 1: Func Group 2: innerfunction(arg) Group 3: .DoSomething() ...
I have a .net 2.0 C# application in Visual Studio 2005 for which I'd like to automatically generate the correct version build number which should contain a number that allows me to guess the build date of the application. I tried to use the 'AssemblyInfo Task' tool from Microsoft but by default this tool doesn't work. For today it would ...
Is there a cost in passing an object to a function that implements a particular interface where the function only accepts that interface? Like: Change (IEnumerable<T> collection) and I pass: List<T> LinkedList<T> CustomCollection<T> which all of them implements IEnumerable. But when you pass any of those to the Change method, are t...
Hello I have on my database a column that holds text in RTF format. How can I get only the plain text of it, using C#? Thanks :D ...
Just a year or two ago I thought that learning WPF is the best use of my free time. Now though, I'm not so sure: seems like the number of ASP.NET jobs vs. WinForms/WPF is something like 10:1. Am I the only one noticing this, or is this really an overall trend? And should all thick-client developers drop everything and begin learning ASP....

Hi I am using a dataset and in that dataset I have a table adapter. In my table adapters I have used stored procedures as queries. If I use the following lines to insert form data using my table adapter, is it safe against SQL injection? Thanks.

I am in the process of unifying these inconsistent naming conventions and this one problem has been a bit driving me crazy lately. In the code base I am working with has no convention regarding "ID"; "ID", "Id" and even "iD" are used inconsistently. **Question: In .NET, how do you guys capitalize "ID"? For an example, nodeID, nodeId? ...
I read in the MS documentation that assigning a 64-bit value on a 32-bit Intel computer is not an atomic operation; that is, the operation is not thread safe. This means that if two people simultaneously assign a value to a static Int64 field, the final value of the field cannot be predicted. Three part question: Is this really true? ...
I have an HttpHandler that acts as a proxy between website visitor and a windows hosted WCF service. Right now the WCF service is setup to handle a json request, but I would like to convert the json request to net.pipe or net.tcp or any of the protocols that WCF can handle. I am hoping to have a communication that goes: client <--j...
hi 1) a) Why is it preferable to bypass DataSet when updating, deleting or inserting records ( I realize using DataSet takes more CPU time and memory, but are there any other reasons besides that?! )? b) Are direct updates faster than batch updates? Why? c) Why do Web services represent only real web application scenario in which ...
hi 1) I noticed that after you close SqlConnection instance, you are still able to re-open the same connection: a) can you tell me what is going on behind the scenes? Meaning, after we close file stream object, we can’t re-open it, but instead must create a new object – so why isn’t the same with SqlConnection objects? b) If pooling ...
For an application I am writing, I want to have extreme extensibility and extension methods seem to give me what I want, plus the ability to call them without an instance, which I need too. I remember reading that static methods are faster than instance methods but don't get the advantages of GC. Is this correct? It's highly unlikely I...
I've started seeing an AccessViolationException being thrown in my application a several different spots. It never occured on my development pc, our test server. It also only manifested itself on 1 of our 2 production servers. Because it only seemed to happen on one of our production servers, I started looking at the installed .net fra...
