Does anyone have any experience hosting the Windows Workflow designer surface? I've seen a couple of rather difficult to follow examples on MSDN, but not much else - certainly nothing that offers an explanation into the process of hosting WF that is clear or easy to read... Are there better resources out there for hosting WF (or a workfl...
I'm trying to install the .Net framework version 2.0 on embedded Windows XP SP2 (aka XPE). I'm using the XPE specific version of the installer from Microsoft: http://www.microsoft.com/downloads/details.aspx?familyid=c4837dad-5719-4b63-8752-cb0a65802329&displaylang=en When the installation starts it fails with the following error: ...
How can I make my window not have a title bar but appear in the task bar with some descriptive text? If you set the Form's .Text property then .net gives it a title bar, which I don't want. this.ControlBox = false; this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedDialog; this.MaximizeBox = false; ...
Let's say I'm working on a little batch-processing console app in VB.Net. I want to be able to structure the app like this: Sub WorkerMethod() ''//Do some work Trace.WriteLine("Work progress") ''//Do more work Trace.WriteLine("Another progress update") ''//...

In .NET (at least in the 2008 version, and maybe in 2005 as well), changing the BackColor property of a DateTimePicker has absolutely no affect on the appearance. How do I change the background color of the text area, not of the drop-down calendar? Edit: I was talking about Windows forms, not ASP. ...
I have a third-party editor that basically comprises a textbox and a button (the DevExpress ButtonEdit control). I want to make a particular keystroke (Alt-Down) emulate clicking the button. In order to avoid writing this over and over, I want to make a generic KeyUp event handler that will raise the ButtonClick event. Unfortunately, ...
I have a situation where I need to be able to load assemblies in the GAC based on their partial names. In order to do this I have added the following to my app.config file: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <qualifyAssembly partialName="MyAssembly" fullName= "MyAssembly, Ver...
As a workaround for a problem, I think I have to handle KeyDown events to get the printable character the user actually typed. KeyDown supplies me with a KeyEventArgs object with the properities KeyCode, KeyData, KeyValue, Modifiers, Alt, Shift, Control. My first attempt was just to consider the KeyCode to be the ascii code, but KeyCod...
When using the unmanaged API for the .NET framework to profile a .NET process in-process, is it possible to look up the IL instruction pointer that correlates to the native instruction pointer provided to the StackSnapshotCallback function? As is probably obvious, I am taking a snapshot of the current stack, and would like to provide fi...
Easy question this time. I'm trying to test whether or not a string does not contain a character using regular expressions. I thought the expression was of the form "[^x]" where x is the character that you don't want to appear, but that doesn't seem to be working. For example, Regex.IsMatch("103","[^0]") and Regex.IsMatch("103&","...
Is there support in Linq to SQL for submitting changes to a single object? The SubmitChanges method sends all of the changes to the database, but what if I'm associating with an errorlog table and only want to save the records going into the errorlog without submitting all of the changes to my other tables? Example: Object Action (ID, ...
a while back I ran across a situation where we needed to display message-boxes to the user for notifications but we could not use MessageBox.Show because it blocks the GUI thread (so nothing on the screen gets updated while the dialog is active). Any suggestions on an alternative? [I coded an alternative at the time but I don't like it....

It seems like Microsoft had a great idea with the ObservableCollection. They are great for binding, and are super fast on the UI. However, requiring a context switch to the Dispatcher Thread every time you want to tweak it seems like a bit much. Does anyone know the best practices for using them? Is it simply to populate an ICollecti...

We have some problems at our production code, my main problem is that we have some process that growing too much, as I think connections that someone forget to close. or maybe a communication error that causes them to be orphans. I am looking for a good tool to explore those process (also threads). I already know the Process explorer, ...
A similar question was asked here, but was specific to .NET 3.5. Specifically, I'm looking for the following: What is the correct way to determine which .NET Framework versions and service packs are installed? Is there a list of registry keys that can be used? Are there any dependencies between Framework versions? ...
