• Windows Forms .Net component for VS2005 UI

  Does anyone know how to build a user interface that is like the IDE style in Visual Studio 2005 What components emulate the tear-away panes and hiding toolbars I noticed that Rapid SQL 7.4 uses the exact same interface so I know that there must be an API out there somewhere. I've seen a few components that attempt to copy the interface but I've never seen anything that explained how to implement the interface like MS does. I'm new to .Net and so if this is a completely retarded question then please forgive me and be merciful/generous with your knowledge. Thanks, No sure if this is what you want, but this control does emulate the IDE of VS 2005, or SQL Server Management Studio http://sourceforge.net/ ...Show All

• Visual C# proper constructor chaining direction

  I was looking at some code at my work and with several overloaded constructors having the same code in each one, I thought, beautiful, perfect place to use constructor chaining. Except I'm not sure which direction is the proper way to go What I mean is, in the constructor, do you go from the general to the specific, using nulls for the missing parameters, or do you go from specific to general and then in the body of the constructor set the missing properties Where things get interesting is when you want to call the base constructor, should it go in one place If you're using constructor chaining, then you can do this, but where does it go, at the top or the bottom of the chain Here is a sample class that illustrates what I mean. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Array of ID3DXMesh causes crash on draw with more than 2 elements

  Hi, Bit of an odd one - I think the solution is probably quite simple but I can't see it so maybe need a few more pairs of eyes please! I've got an array of ID3DXMeshes, and for each one I do D3DXCreateMeshFVF, then fill the vertex and indexbuffers. I then go thru the array and draw them. If I have just one element in the array, all is well. It gets drawn and it's released ok on exit. If I have 2 elements, it gets drawn ok but crashes when I try and release element[0]. If I have more than 2, it just crashes when it tries to draw the first one. I've been looking at this for ages now and am going a bit mad! Any help would be great. Below is the method that creates the meshes, the method that draws them, and the code where they are dec ...Show All

• Windows Live Developer Forums Looking for skilled API developer

  Hi All --- I'm interested in developing an activity that would be a database of profiles for a gay dating service.

• Software Development for Windows Vista Vista MCE SDK - Can't view the filtergraph

  I can no longer access Media Center's filters from Media Center's filgraphmanager exposed in the ROT. I've upgraded my machine to Vista Ultimate , and downloaded the " Windows Media Center Software Development Kit for Windows Vista RC1 " In previous versions I was able to get the filgraphmanager and enumerate the filters in the graph, but now when I enumerate the filters in the filter graph Media Center exposes in the ROT, I get no filters back. Is this a known issue And is there a better way to get the video and audio stream from Windows Media Center Thank You, Matt ...Show All

• .NET Development monitor/lock scope etc

  Some musings on synchronization ... Does a lock remain in effect if the critical section contains a call out to another method I'm sure I've read somewhere that it does but I can't find the reference. What happens if the called method is public and also has to implement synchronization If it locks on the same object there will be a deadlock. If a ReaderWriterLock it will just increment the lock count right I assume that's ok, but it will degrade performance. Does it make any difference if a return statement is inside or outside the critical section I assume not. Say I create a thread-safe wrapper for a collection class. I have to wrap GetEnumerator() but putting it in a critical section is pointless because the returned enu ...Show All

• .NET Development .NET 1.1 to .NET 2.0 Upgrade Logical issue

  Guys, I am new to .NET Framework and .NET development, my Boss asked me to findout that either we can Develop and run our .NET 1.1 application under .NET 2.0 I think that for building and running VB.NET applications under .NET 2.0 we need to have VS 2005 and is it possible that I can built applications in VS 2003 and run it under .NET 2.0 Just need to clerify from you guys first Thanks in advance .NET Framework installs side by side, one does not conflict the other. You can run .NET 1.1 apps in .NET 2.0 I believe, I've tried it, but you cannot run .NET 2.0 apps in .NET 1.1/1.0. It's not backwards compatible in order to develop .NET 2.0 apps, you need VS2005. VS2003 and earlier do not run under/compile wi ...Show All

• Visual C++ Problem with custom manifest file when building but not rebuilding

  Hello, I have a simple dll using a custom manifest file in order to refer to the MFC80 libraries previous than service pack 1. When I rebuild the solution the linker takes the right manifest file and everything works fine. When I modify a cpp file and just build the solution (compiling just that file) and link the embedding file step is not performed and the dll cannot find MFC80 during run-time so my application cannot start; maybe it takes a wrong manifest file. The work around I found is as follow: delete the file mt.dep before compiling my solution. In that case the embedding manifest step is performed and the DLL can find MFC80. Is this behaviour a bug ...Show All

• .NET Development C# xpathnavigator: how to retrieve element names

  Hello, At the risk of being criticized for not comprehending reference materials I will ask one last question, then I’m going to take the brute force method and write a parsing routine of my own in C# since I can’t seem to get XSLT or the built-in C# features for processing XML to work to my satisfaction. After reading and re-reading all the information you people have provided I’ve decided to use xpathnavigator in my C# program. Here’s some code: string XMLquery = @"/df:xtvd/df:programs/df:program[df:title='NOW']/df:title" ; try { XPathExpression query = xPath.Compile(XMLquery); XmlNamespaceManager manager = new XmlNamespaceManager (xPath.NameTable); ...Show All
