Visual Studio Express Editions Visual Basic 2005 Express Questions
Hey Guys, I'm trying to break into the world of desktop programming.

I do understand that for simpler programs where I am changing values and putting them into a message box or into another value to put into a text file or database.

Visual Basic Resolving Assembly Usage.
How can i resolve if some .Net ...dll is used by any (or defined) .Net application, not touching this application. Ok, I say in another way. "Not touch" i mean - not to correct code in it and add some methods. But the main thing is that i need to do it in runtime, that mean when my programm runs it has to check if some .Net dll (determined) is already used by another programm, and it's great to know wich programm... ...Show All
Visual Studio How to delete a VSS database?
Hi, I was wondering how I can delete a old vss database (In both VSS 6 and VSS 2005). I created a new database in the wrong location and I want to remove it. But I can't seem to find a way to do this... Hopefully someone can help me with this. Greets, El Loco To delete a VSS database, simply delete the database folder from disk... If you want to unregister it from VSSExplorer (instead of deleting physically the database files), open File/Open SourceSafe Database dialog, select the database and press the Remove button. You cannot remove the current database (if you already have it open in ...Show All

Visual Basic Set Starting size for a child form
Is there any way to set the starting size for a child window in a mdi form. Whenever I open the child form it sizes it based on the size of the parent form, instead of using the size I set for it in the designer. I use Form2.Size = New Size(640, 480) . Is there another way An MDI (Multiple Document Interface) child form can be programmatically sized. After you assign the MDIParent property to it, just prior to "show"ing it, set it's size New Size (640,480) For those of you confused about this, the MDI is the type of interface that Visual Studio uses (as well as older versions of MS Office, etc). Whereas your document ...Show All
Visual Studio 2008 (Pre-release) Middle Tier Server using WCF
Hi, Please, I need to know if it is possible convert my Middle Tier Server to WCF and how. Using 100% .NET Remoting I wrote a middle tier server named ‘Endomap – Enterprise Domain Application’ to easy administrate connections and application servers. Like an IIS, but only for ‘Smart Clients’, so it is : 1) A windows service (EndoServer) that runs your middle tier Assembly/DLL's in one or more AppDomains. You give your methods the <RemMethod> attribute to make them available to external callers and intercepts. For example: [ Remotable ( typeof ( IHello ))] public class Hello : ContextBoundObject , I ...Show All

.NET Development Performance issues with System.Collections under 2.0?
I have an application (originally written using the 1.1 framework) which performs numerous ArrayList.Contains and Hashtable.Contains method calls using various reference types (which have NOT overriden getHashCode and Equals). When running the same code compiled against 2.0, the total speed of the application is significantly reduced. By doing a bit of performance analysis it would seem that these operations have just gotten slower. The default implementation of object.getHashCode also seems to take longer in 2.0. Has any of the underlying library code changed for version 2.0 which may explain these results Any clues as to what may have c ...Show All
Visual Studio SourceSafe Web Service Configuration
A collegue of mine has just setup a SourceSafe 2005 database and configured it for internet web service access. I have Team Suite installed including SourceSafe 2005, but I am unable to find an option anywhere which would allow me to connect to it. I can connect over a local LAN or over the net via file sharing, but I can't find the web service protocol. I was informed this feature was in Beta 1. Anyone know what happened to it I thought Beta 2 was feature complete since the Go Live license is available.... Now i managed to get it to work. I had enabled the internet access while the proj ...Show All
.NET Development TCPClient just "hangs" when unable to connect
I am developing on a WM5 smartphone device. I have not had this problem for WM2003SE smartphone devices, infact the code is the same except the .NET CF versions are different (1.0 and 2.0) Problem is, when I try to connect to a computer from the WM5 device, I do this: this.theTcpClientProtocol = new TcpClient(someServerName, somePort); this.theNetworkStream = this.theTcpClientProtocol.GetStream(); problem is, if the application on the server end has not started the service, in other words it is not running making the port available - when creating the new TCPClient object it just hangs endlessly! ...Show All
