I need to know if I can create a file in a specific folder, but there are too many things to check such as permissions, duplicate files, etc. I'm looking for something like File.CanCreate(@"C:\myfolder\myfile.aaa"), but haven't found such a method. The only thing I thought is to try to create a dummy file and check for exceptions but th...
The title pretty much sums it up, and I'm sure there's a perfectly valid explanation, but it seems extremly odd that loading pages(after they're compiled) on my local computer seems to take forever, when the same code is blistering fast when "live". I'm developing on Vista, IIS7, pretty ok hardware; while the server is a single machine,...
In .NET, is there a tool or some other method which would allow us to modify an assembly's manifest, without having to modify the AssemblyInfo and re-build the assembly? Thanks ...
I'm looking for a generic method to implement a wait screen during long operations. I have used threading a few times before, but I have the feeling that I implemented it either very poorly, or with way too much hassle (and copy/pasting - the horror!). I want to keep this as generic and simple as possible, so I won't have to implement l...
I have need to select a number of 'master' rows from a table, also returning for each result a number of detail rows from another table. What is a good way of achieving this without multiple queries (one for the master rows and one per result to get the detail rows). For example, with a database structure like below: MasterTable: -...
What's better for DSL: TCL or Lisp? What can you say about Java(C#)-TCL binding versus Lisp(Scheme)? What DSL tool is applicable for .Net development? (excepting Microsoft DSL tools) ...
I would like a class to implement an interface, I do not want to change the original class (that would add undesired dependecies). I know I could inherit from the class and make it's child implement these methods, but then I am faced with a problem how to convert the parent class (that come from the data / ORM) to this presentation clas...
I have a class in my domain model called JobPlan this class is stored / retrieved via ORM and used on various places. I am creating a view that shows a treelist of this class and the treelist needs this class to implement certain interface (the interface comes from a 3rd party lib). Adding the interface to the JobPlan class will ho...
The Version class in .Net does not implement the CompareTo interface as I would expect, it seems to handle the compare alphanumerically instead of comparing the four numbers. Maybe not a bug, but a 'feature'. Can anyone shine a light on why the compare (and also the standard <, = and > operators) do not work as I would expect below? ...
In my application I have several DataContexts that connects to different databases with different schemas. In a custom user control I display the results of the query and let the user edit them, and when the user edits the data I want to persist the changes to the database. To do that I need a reference to the source DataContext (or at l...
There seem to be many options to create an XML document in .NET. What's the best approach? ...
Can anyone recommend any specific books on C++/CLI, particularly with reference to .NET and Visual Studio. It seems to me that there is very little out there, a few APress books with a couple of comments each on amazon. I'm looking in particular for something that isn't an introduction to C++, but something more Microsoft specific. Than...

Because i'm making a windows Form window and the PictureBox inside that contains my dynamic image .. do i need to add some special code when the form is terminating, to dispose of this? here's the...
When ever I think I can use the yield keyword, I take a step back and look at how it will impact my project. I always end up returning a collection instead of yeilding because I feel the overhead of maintaining the state of the yeilding method doesn't buy me much. In almost all cases where I am returning a collection I feel that 90% of t...
Hi all, I'd like to allow a user to open files in their own client applications via Silverlight. I'd like this to work similarly to WebDAV, in the sense that they could read/write the file back into Silverlight's isolated storage... Is it possible to construct a file:// link to an isolated storage file? Is there a uri scheme that is def...

Sometimes, while I am debugging a c# application, I will hit a break point and when I try to continue, step or step into, it just does nothing. The yellow line highlighting the current line goes away, but it never reaches the next line. The app is still frozen like I am on a breakpoint and I can do nothing but hit the stop debugging bu...
I have a .NET assembly which I am accessing from VBScript (classic ASP) via COM interop. One class has an indexer (a.k.a. default property) which I got working from VBScript by adding the following attribute to the indexer: [DispId(0)]. It works in most cases, but not when accessing the class as a member of another object. How can I get...
