• Smart Device Development Defragmented Internal Memory

  Is there a tool that can be used to defragment internal memory. Not an SDCard. I have found lots of tools for that. But nothing for internal memory. Any odeas Thanks What benefits are you expecting from it Defragmentation of hard drives improves performance because it takes some time for HDD heads to move from one file fragment to another. There's no such time penalty in RAM based storage, reading next memory block is just as fast as reading one 30 MB away. By the way, modern flash cards (access time below .5 ms) are also affected by that insignificantly. Defragmentation of a flash card is unlikely to yi ...Show All

• SQL Server Stored procedure issues...

  Hi, I have a table set up in SQL Server Express with the following columns: PartNumber (PK, smallint, not null) PartName (nchar(50), not null) Status (nchar(10), not null) Price (decimal(8,2), not null) What I want to do is create a simple .Net form where the user types in a search key and the key is matched against the PartName field to provide matches. This was easily done in the .aspx file itself: SELECT * FROM dbo.PartsTemplate WHERE PartName = @PartName ORDER BY PartName ASC It works exactly as it should. However, since I'm still learning my way around SQL Server Express (and to a degree SQL itself) I wanted to try creating it as a stor ...Show All

• Visual Studio Addin for Visual studio 6.0(msdev.exe)

  Hello, I am trying to develop an addin for Visual studio 6.0(msdev.exe). I am using DevStudio Add in Wizard for it. It provided me default code for handling application events and debugger events. But my objective is to handle copy,cut,paste ,print commands in editor.These command are not the part of IApplication events or IDebugger events. Could anybody please help me in finding the best possible solution for this. As per my understanding Cut,Copy,Paste methods are part of ITextselection interface ,which i try to implement in my class,but unable to handle those events as there is no proper event passing. Thanks and regards, Ruhina. ...Show All

• Visual Studio IVsHiColorItem caching

  I've implemented an editor line marker that implements IVsHiColorItem to allow the full color range. This part works. Now the trick is when I change that color, I've found that the GetColorData member is only called seemingly once per-marker-per-editor-class, so color changes don't take effect until a VS restart. I've tried clearing the font and color cache with IVsFontAndColorCacheMangager.ClearAllCaches, and this didn't have any affect on my marker. What do I need to do in order to get the GetColorData to be called again after a color change Will, I am a bit confused about what you are tr ...Show All

• Visual Studio Customize DirectiveProcessor

  Hi, I have a small question regarding Directive Processor. I created a new DSL named Performance and intended to enhance some functionality of generated PerformanceDirectiveProcessor class. But it is sealed instead of partial class. So, if I want to more functions to PerfomanceDirectiveProcessor I need to create a new class including old and new functions. Is that right Also, I don't know the diffenece between RequiresProvidesDirectiveProcessor and DirectiveProcessor classes. Which one is more powerful Sorry if my question may sound a bit silly.

• Visual C# STA MTA issue: handle returned is IntPtr.Zero when in MTA mode

  I'm writing a multi-threaded application. When I call IntPtr hInterface = mySimCan.CanOpenWCS( "CAN1" ); in the main-function of the application the hInterface contains a valid handle because the main-function has a [ STAThread ] attribute: [ STAThread ] static void Main( string [] args) { But when I call it in one of my threads the returned value is IntPtr .Zero The method CanOpenWCS is located in a C# managed DLL (class library project).

• SQL Server Reporting Services - Variables/Parameters - Is this a bug?

  When creating a Reporting Services report and declaring local variables as part of your query in a dataset there is sometimes a problem. When you hit run in the Data section and the “Define Query Parameters” box pops up, all the variables are not there. Sometimes when you go to properties (…) of that dataset the parameters are gone.
