• Visual C# Spectrum Analyzer Question

  Ok. This is actually a very odd question it would seem. But I would like to know how to create a Spectrum Analyzer. I know it has something to do with FFT (fast fourier transform) algorithm, but I just dont know where to start. If someone could help or point me in the right direction it would be appreciated. Maybe DirectShow can do this for you. You might want to try asking somewhere like: http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=129&SiteID=1 for better advice. If DirectShow can't do the FFT itself, your next step is to figure out how to get the audio samples in the time domain. These are just numbers (probably at 44 ...Show All

• Visual C# !!! IF MICROSOFT HEAR US!!!

  I just saw another thread with "Can i make a app that doesnt use the .NET.  The framework is too big 23 MB".. SO... Can Microsoft create a .Net Framework just for c# not for asp or j# or visual basic providing only the neccesary dlls Please!!!! Eh, the framework is for .NET; there are in my opinion no specific dll's for j#, vb.net, etc... The CLR uses IL, and C#, VB.NET, J#, and all other .NET languages are compiled to Intermediate Language. ...Show All

• Windows Forms Type.GetType and Colors

  I have a code editor where I use reflection to lookup types descriptions. If I have code like this: Type type = Type.GetType("System.Drawing.Color, System.Drawing"); the variable "type" is null. Does anyone know how to use the Type.GetType function to get the Color's type I cannot simply use Color.GetType() because this is for a generic code editor that does not already have the type definition for all classes in all loaded assemblies.

• Visual Studio Team System Associating one Work Item with other Work Items.

  I am trying to define my own work item called Milestone. I would like to associate one or more other work items (like Bugs, Tasks) with this Milestone. The idea is that I cannot finish (set “Finished” state) my Milestone unless every work item associated with my Milestone is finished. I cannot also associate one Milestone with other Milestone. The problem is that I don’t have any ideas how to code this in XML. As a base model to modify I am using MSF for Agile. The next modification I wont to make is to associate every iteration with one or more Milestone. End of every iteration should mean finishing one particular Milestone. The ...Show All

• Visual Studio Tools for Office VSTO, SQL, Excel, and Cell Locking

  So I'm very new to VSTO, having just started using it two days ago, and have been teaching myself pretty well(it seems) using the Carter/Lippert book in the .Net Development Series.  I have encountered, however, a problem that the book does not cover thorougly enough, and was hoping for some advice on how to solve a tricky problem. My current project is to load and process data from a SQL server(which I do just fine), and then display it and allow the user to edit only certain parts of the data. Currently, I have two listobjects, one populated with data I do not want to be changable, and another that I want to be completely modifyable.& ...Show All

• .NET Development Adding a Column to a Datatable to hold images

  The basic system types do not include image. I want to add a column to a datatable which will hold images. I can add system.object and put my imagelist.image in the column. My DataGidView does not create an image column. Instead I see system.drawing.bitmap in a text column. Not surprising considering object is not image.
