• Visual Studio 2008 (Pre-release) WCF and application design

  Hello All, I'm looking for some design guidance about WCF. I want to build an application where my business objects live in one process (the server). I want to be able to attach arbitrary UI’s (or interested parties) to this process to display information about the business objects, as well as manipulate them. These UI’s could live on the same machine, or on other machines. I would like provide a uniform interface to these UI’s regardless of where they live (same machine or other machines). It seems like this is an ideal circumstance to use WCF (based on the whitepapers on WCF), but once I started playing with the June CTP I began to wonder if WCF would be the approach Microsoft had in mind for this situation. ...Show All

• Visual C# DateTime Difference on WinForm and WebForm!

  I write a simply code to see the difference: this .label1.Text = DateTime .Now.ToString(); this .label1.Text += " " + System.Globalization. CultureInfo .CurrentCulture.ToString(); The output of WinForm is “ 28/11/2006 11:03:21 en-GB ”, while WebForm is “ 11/28/2006 11:02:55 AM en-US ”.

• Visual Studio Team System Team Foundation Server vs SubVersion

  Hi, Did any one has done comprehensive report comparing Team Foundation Server vs SubVersion vs VSS The comparison will be toward business decision. - Cost analysis. How much saving if using TFS compare to others - Efficiency & Productivity - Quality Assurance. - etc Thanks, John > Sourceforge is using SVN too - should they use TFS in future Errm. No. If you wanted a Sourceforge like site that was using TFS, then check out the excellent CodePlex site ( http://www.codeplex.com ). You are correct that you need a Microsoft platform to run TFS on. For the kind of organizations that TFS is aimed at, this is not a problem. Considering how new TFS is, the adoption has been staggeringly ...Show All

• .NET Development Performance: Passing large arrays from .NET to COM components

  Hi, I am working on a COM component in C++ that will be used by .NET clients. Clients frequently pass large arrays of points in Cartesian coordinates (i.e. XYZs) to the component. I'd like to know the most efficient way to do this. My tests show conformant arrays are ~7 times faster than safearrays. Safearrays were ~6 faster than sending the array's data one point at a time. So I'd like to use conformant arrays, but I want to make sure they are "safe." Here is my IDL struct Vec3 { double x; double y; double z; }; HRESULT SendData ( [ in ] int numPts, [ in , size_is (numPts)] struct Vec3 pts[]); And it is called from C# with code like this: GCHandle gcHandle = GCHandle ...Show All

• Windows Forms User interface question

  Hi all, I'm building a software which has a UI similar as outlook 2003. The problem I'm facing is how can I perform dynamic content change while the user click the navigation buttons. I did think about using MDI but that is not what I want as it obviously not how the outlook implement. Thus, i think about using panels and swap between them. However, it seems very hard to design as i need to cover a new panel to the previous one. It anyone can tell me how outlook implement the dynamic content change thxs alot. Create a custom usercontrol for each view. This way you can just toggle their visibility depending on the button that was click. Usercontrol creation is the key to creating a UI ...Show All

• Software Development for Windows Vista Compatibility settings not working after uninstall / reinstall

  Our application launches other executables that require elevated permissions to run. These other executables were sometimes failing to launch the first time the application was run and succeeding after that, and sometimes failing to launch no matter how many times we tried. We implemented a workaround of setting the registry key HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\[app path] to ELEVATECREATEPROCESS. This worked great - our programs would now launch correctly and ask for elevated permissions as expected. However, if we uninstall the application and then reinstall it, the workaround no longer works. We are removing the registry key that we created when uninstalling and creating it again when installing. If ...Show All

• Windows Forms can't change mouse cursor position...

  Hi, I'm trying to change the mouse cursor position with: Cursor.Position = New Point(0, 0) But it doesn't work. If I watch the value of "cursor.position" right after this line is executed, I see that it did change, but the mouse cursor didn't really move. Any ideas it should move, I've been able to do it! :-) tried moving it somewhere else like say 100, 100 What about doing it this way, even though it shouldnt make much different: Dim thePoint as new Point( x, y ) Cursor.Position = thePoint ...Show All

• Software Development for Windows Vista CreateInstance failed

  Here's the situation. I have a XAML only workflow in a C# project (A). The workflow references custom activities (derived from Activity etc) that are built in a separate project (B) in the same solution. The reference is via a namespace reference in the workflow XAML. (...... xmlns:ns0 = " http://ABC/ActivityLibrary ....) Project (A) has a reference to the dll generated by Project (B). It's a direct reference - the reference is created by pointing to ProjectB.dll in a common directory. One of the types in (B) contains the following directive to map the namespace identifier to the assembly [assembly: XmlnsDefinition ( "http://ABC/ActivityLibrary" , "ABC.UI.ActivityLibrary" )] I open Visual St ...Show All

  Hi, I am learning Visual studio 2005 Express Suites (very new learner).

  How do I go about understanding and converting the coding of .NET 2.0 into the coding that Visual Basic 2005 Express Edition can understand Spotty, I find these sites to be highly fallable.
