• Visual Studio Visual Studio 2005 and Source Code Control

  Hi all, I'm starting a new set of projects mainly done in Visual Studio 2005 (VB and C#). I want to use a source code control but I don't know which one to chose (open source). In VS6 I used to use CVS but I don't know if it's a good choice for VS2005. Lastly I've heard many things about SVN but I don't know its behavior within VS2005. I'd like to know your recommendations/choice between CVS and SVN. Also, if you definetily preferer SourceSafe, I'd like to know why and if you have compared them. Thanks in advance, Marc Soleda There are not very many CVS and SVN users here. (I would definitely prefer SVN over CVS myself.) You might want to ask on the forums dedicated to those products. ...Show All

• Windows Forms Child components in design time

  Hello, I created a custom component. this component exposes two "ImageList" properties. I would like to make this two ImageList accessible in designer. For example, I create one MyCustomComponent on my form, then I create one ListView on my form. I would like to assign listView's SmallImageList property to MyCutomComponent.FirstImageList. I can do this at runtime, but I think it is possible at design time. I try to implement IContainer and INestedContainer but it is not solution. Thanks for your help ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX 10-Vista

  I owe a computer with W. XP.I'm going to upgrade it to Vista.My question is if directX 10 needs only Vista to run.My system is fueled by ATI radeon x1600 pro.Do I have to change it or just have Vista hmm, i'm not sure. Graphics cards have nothing to do with your processor. If the card fits in your pc it should work. If intell graphic cards would only work on intell based systems they would loose a lot of customers cause most gamers use AMD. Its just a brand. If the intell DX10 compactible card will be low budget i hope they work on AMD cause i have amd myself and a low budget for these kinda things :) ...Show All

• Visual C++ Decorations on C++ DLL function declarations really needed?

  I used the _stdcall decorators on the Visual C++ function definitions and declarations, but I couldn't get communication between the DLL and the Visual Basic application that was trying to call the functions of the DLL.. When I removed the declarations from the VC code almost completely (all but for the DLL_Main function definition), it worked fine.  Is there any disadvantage to using this approach   Everyone I communicated with about it , including my boss and people that answered the MIcrosoft help posting that I put up, stated that you have to use those decorations.  Why is that   It works fine without it so far.  My boss will be back from travel tommorrow.  I was hoping to find out today so I can make ...Show All

• Software Development for Windows Vista Single-instance DCOM server problems with high/low integrity levels

  I am working on an application that employs a single-instance DCOM server. The application works fine on all other versions of Windows except Vista. There is a strange behavior that I observe on Vista in regards of the instantiation of the singleton COM interface if there is a difference between integrity levels of the server and client applications. The single instance is accomplished by having the singleton interfaces declared with DECLARE_CLASSFACTORY_SINGLETON ATL macro. Additionally, there is a code in the application that ensures only one instance of application is running by utilizing a named mutex. The application checks if the mutex exists, exits if it does and stays running otherwise. The scenario of the problem I pbserve is the ...Show All

• SQL Server Deploy packages to an MSDB subfolder

  In SSIS you can create subfolders in the MSDB folder. However, when deploying a SSIS solution to the server, it seems you cannot specify a subfolder. When selecting MSDB as the target, all packages in the solution end up directly underneath the MSDB folder. Is this a simple fact of life, or am I missing something here Is there a way to deploy a SSIS solution to a certain MSDB subfolder I really would like that to keep my packages organized. Thanks, Hans Geurtsen. When you create the subfolder in msdb, you can rightclick on the folder and choose import package. thats the only way i find to get the files in that folder (you can rely on serverstorage as well here) ...Show All

• Visual Studio Automation Events in a Package

  I'm trying to capture debugger events through the Automation model from a VS2005 Package like below, and its not working, any suggestions why _dte2 = (EnvDTE80.DTE2)Package.GetGlobalService(typeof(SDTE)); EnvDTE80.Events events = _dte2.Events; DebuggerEvents debuggerEvents = (EnvDTE.DebuggerEvents)events.DebuggerEvents; debuggerEvents.OnEnterRunMode += new _dispDebuggerEvents_OnEnterRunModeEventHandler(this.OnEnterRunMode); Thanks, Grem Hi Grem, This is an oft asked question in this forum, though I haven't seen it recently. The problem is that your debuggerEvents variable is going out of scope, when this code exits the function it is in.

• Visual Studio 2008 (Pre-release) reproduce DWM technology

  Hi, As I understand, the DWM run as a full screen WPF application that “captures” the rendered output of each application and it redraw each of them. It sounds simple but probably I miss something. Is it possible to capture the output of running applications, convert it and manipulate it with vector transformations thank you. - the DWM is unmanaged code. It therefore does not use WPF. It uses the lower-level MIL APIs, which incidentally are not public (at this stage). What happens, is that when applications ask for a handle to the screen to draw on (as they would do directly in XP), they are now given a handle to a surface to draw on instead. That surface resides in memory. DWM has algorithms built in, so it knows when ...Show All
