Sabrecat Uninstalling .NET Framework 2.0 on Vista?
Having a problem with our new Vista Business install, where I can't seem to find a way of uninstalling .NET 2.0. 3.0 was easy to remove through Add/Remove Programs, but no entry for 2.0 unless I am missing something. Newb to Vista, relatively new to development. I have run the "cleanup tool" and it doesn't find 2.0, but it is installed: c:\windows\microsoft.net\framework\v2.0.50727 Thanks for any help/insight. C. I'm starting to think that maybe this is just not possible. From what I've "gleaned" approximately 4% of Vistas code is managed code built on .NET 2.0. If that's the case, maybe there is no way to unistall 2.0 w/o rendering the OS unstable ! ...Show All

xRuntime IEnumerable.GetEnumerator()
Greetings, I have some questions on IEnumerable.GetEnumerator(): 1. Should each invocation return a distinct enumerator object 2. If so, should the enumerators keep their state in sync or independent of each other 3. If independent, can distinct enumerators (returned by the same method) enumerate the underlying collection in different orders MSDN Lib seems to have left these unspecified, so maybe it's all up to the method implementer, but since the interface is tied to foreach sematic, perhaps there are specific answers/rule for the interface If MSDN Lib specifies the answers to these, I'd be grateful if you can point me to the URL. Thanks for any info, Dasa Thanks for the replies. ...Show All
USMCNJ Accessing one forms class properties from another
I have a main form which has created instances of various classes it uses. When a menu option is clicked I want to open another form ,a bit like a dialog window, which enables the user to set various properties in those classes. How do I do this so that this second form has access to the properties of the first forms class instances The properties I want to access are not static. Regards, Gareth Pass a reference to the main form in the 2nd form's constructor. Something like this: Form1.cs: private void toolStripButton1_Click(object sender, EventArgs e) { Form2 f2 = new Form2(this); f2.Show(this); } Form2.cs: public partial class Form2 : Form { private ...Show All
Mturco11x Dedicated thread calls GUI thread directly
In an app I'm debugging I've come across some code in which a method called from a dedicated thread directly accesses a property on a GUI control, created on the main thread. It has, so far, not caused any problems but I am told that this is bad. Before I fix it, could someone provide, or point me in the direction of, an explanation of why this is bad, and what kind of problems it can cause. Also, is there some kind of profiling tool I can use to monitor method calls across the threads and make sure that what I think is happening is actually happening Any help appreciated.

radhaps ::OpenEvent can't find events created in managed code?
I wonder if people have experienced a similar problem. I have a client app which uses EventWaitHandle to create an event and see if anyone shuts it down: EventWaitHandle eventHandle = new EventWaitHandle(false, EventResetMode.ManualReset, Program.EventName); if (eventHandle.WaitOne()) // we recieved a shutdown event this.Close(); There is a C++ component that needs to signal that event like so: HANDLE eventHandle = ::OpenEvent(NULL, FALSE, _T("random-name")); if( eventHandle ) { ::SetEvent(eventHandle); ::CloseHandle(eventHandle); } The ::OpenEvent keeps stubbornly not finding the event by name. On top of that I can actually create an event with that name ! Thoughts ...Show All
Prajakta Chavan Fatal Flaw in the Large Object Heap?
Hi All, After playing with the GC I find the following interesting. The problem domain I typically work in requires the allocation of very large arrays for image processing. We have discovered some issues when our processes are long running. We run out of memory and can not reclaim it. Our only recouse is to restart our processes. In an effort to discover why I uncovered the following: The LOH (Large Object Heap) is never compacted. I think this is a fatal flaw in the GC. I understand MS stated reason for this, but shouldn't there be someway to compact the LOH if necessary, at least a method call that forces the issue Does anyone know of anything that can be done Any workaround is better than killing the process... Here is a demo ...Show All

Charlotte Adam Desktop Notification using Windows services
Hi How to create Desktop Notification using .NET windows services,C# in Windows Vista Operato System Regards Govardhan http://msdn2.microsoft.com/en-us/library/ms683502.aspx . You don't want to do this (for security reasons). You probably want to have a separate windows application that runs in the users context that uses some sort of interprocess communication (i.e. named pipes) to get notifications from the service. Best regards, Johan Stenberg Could you provide more detail What do you mean by Desktop Notification I believe you'd have to P/Invoke WTSSendMessage if you want the service itself to display the message box. Please note that this is not an optimal solution, and that you' ...Show All
