• Visual Basic Newbie: VB 2005 Express & Form Inheritance

  Beg pardon, but I'm 5 days into a long journey to learn .NET.  ;-)  I downloaded VB 2005 and bought a few books on VS 2003 to get started. On a chapter concerning form inheritance, and on the Help documentation of VB.NET Express, it looks like I ought to be able to inherit a form by clicking Project, Add Inherited Form.  From reading this forum, it looks like in the Express edition, that menu navigation may have been removed from Beta 2 (which I'm using). Okay, then, it seems like there is another way to do the same thing, but I'm hung up on the actual code changes that lets me inherit one form into another. In my project, I c ...Show All

• Visual Studio Team System Correct name: TFS Version Control or TFS Source Control

  What is the correct way of referring to the new Source Control System that comes with VSTS When you select the Source Control Item from the Options dialog in Visual Studio Team Edition for Developers (Tools | Options) it describes the 'current source control plug-in' as 'Visual Studio Team Foundation Server'. I'm hopeful there is a more descriptive name like 'TFS Source Control'. What is it In one document Microsoft call it Source Control and in another its called Version Control. Regards Will Thank you both very much for making this clear to me. In summary, I believe it is correct to say: 1. SourceSafe i ...Show All

• Visual C++ FindWindow() not finding anything

  I'm using FindWindow() in VisualC++ inside a thread before I do a PostMessage() from the thread to the parent window. But, the debugger indicates FindWindow() is not "finding" anything, so the message handler in the parent is never being called. This logic appears in the thread: static char* xxx = "CMh53View"; // HWND zzz = FindWindow(xxx, NULL); // this doesn't work either HWND zzz = ::FindWindow(xxx, NULL); I define the class name that handles the window logic as: class CMh53View : public CFormView How can I get the thread talking to the window You were right. All that stuff in the debugger about &quo ...Show All

• .NET Development I want the CLR to probe the local folder BEFORE the GAC

  Hi,   I have some assemblies in the GAC.   I am running an exe from a folder, and the assemblies in the GAC are also in the same folder as the exe.   Is there a way to stop the CLR from loading the assemblies from the GAC and load them from the folder (if they are found)   Is there an element I can add to the .config file for the exe I am running to tell it to do this   Thanks. The supported way of doing so is to using DEVPATH http://msdn2.microsoft.com/library/cskzh7h6.aspx More of it in my blog http://blogs.msdn.com/junfeng/archive/2005/12/13 ...Show All

• Windows Forms Is there a way to programatically control Windows' "Unplug or eject hardware" functionality?

  An example of this functionality is if you have a usb hard drive for example. When you are done using it, it is recommended to double click the "Unplug or eject hardware" icon in the system tray to safely stop/shutdown that device. As .NET can pretty much do anything :), is there a way to control this functionality programatically and automate it. The reason I ask is that when I plug in my usb hard drive, I want it to do a quick sync and then stop itself so I can unplug it right after it's done without harming the data. I have a feeling Windows API calls will be necesssary, so any help you could give would be great! ...Show All

• .NET Development Socket, detect message boundaries for objects - working code?

  Hi, I'm stuck with a problem that is bugging me for days. I'm custom serializing objects and sending them across async TCP sockets. However, I have a problem deserializing messages when the receive is split up in different packet sizes and I just can't figure out how to get it right. The problem is, that all works fine for a couple messages but then the header size is read incorrectly (I'm sending a header for each messages that tells the length of the incoming message so I can detect the message boundary): 2005-11-21 16:13:12.0468|INFO|Test.Server.ClientCommunicator.Server|Received connection from: 127.0.0.1:1990 2005-11-21 16:13:12.109 ...Show All

  I used search but was unable to find the answer to my question. What i am trying to do is to make my progress bar show my status in my Windows based application. To give some program background, i am writing an update program that will convert all information from the old program's .cad(txt) files to a new MSDatabase. The update works correctly, but due to the lentgh of time it is taking we are trying to add a progress bar or a list box to display our current progress in the update. The program form has 1 button for each item (ie. "Pen Numbers" button - max 14 buttons) so we were able to test each function without running the entir ...Show All

• SQL Server Database Snapshot on tempdb

  Hi Experts: Can you please offer an explanation on why a database snapshot cannot be created on tempdb . Is it because the tempdb is created everytime fresh when SQL Server is restarted or some other reason . Any insight is appreciated.
