• Architecture Inheritance

• Software Development for Windows Vista Bug with Vista and InkAnalyzer

  Hello everybody, this is the real Problem of the thread I posted some hours ago. I had problems with painting ink into a Bitmap - I could'nt see any ink. But it was no problem of the painting-prodecure itself - there really was no ink. ;) Before my program draws the ink into the Bitmap it reads the RecognizedString from the used InkAnalyzer. And since Windows Vista this InkAnalyzer works abnormal - it deletes every stroke out of the InkOverlay-Object whenever I call the GetRecognizedString-Method of the InkAnalyzer. This happened not when running under Windows XP. Is this a known bug Or is it a feature ;) Well, no. I guess it's a bug. Is there any workaround beside not using this method anymore Will there be an upda ...Show All

• SQL Server How to get an absolute sum for all values in a certain level in a hierarchy

  I am looking at a cube using excel. I have added two dimensions to row fields and one to the columns (date). Is there any calculation that will return the sum of a specific measure for one of the dimensions regardless of what is selected for the second dimension The dimension in question is a hierarchy and I want to get a sum for a certain level in the hierarchy. I have tried SUM with ANCESTORS but it still only returns the sum as constrained by values selected for the second dimension. Here is what I was trying: CREATE MEMBER CURRENTCUBE.[MEASURES].[Portfolio MV] AS Case When IsEmpty([Measures].[Market Value]) Then 0 When [Portfolio].[Portfolio Name].CurrentMember.Level Is [Portfolio].[Portfolio Nam ...Show All

• .NET Development Retreive incoming IP Addresses?

  Is it possible to get the incoming IP Addresses and display them in a listview Thanks, Loopback address prefix would only give you connections made to your machine to the loopback address i.e. connections from your machine to your machine. This would not help you. You dont need a web server, just a way to monitor traffic and connections to an existing web server. ...Show All

• Visual C# WM_DEVICECHANGE msg for CF/SD card reader

  Hi, I am working with a CF/SD card reader. My application needs to get notified when a new card is inserted into the card reader. I have overridden WinProc and listening to a WM_DEVICECHANGE message - and it works fine when attaching an USB flash memory, my camara or inserting a CD. But I am missing an notification when I am inserting a CF or SD card. Windows itself seems to get informed by this, because the drive label changes to the volume name of the card and autoplay is started. The card reader is similar to a CD/DVD drive: one drive for each card type, present in the Explorer regardless if media is inserted or not. What do I need to do to get a notification Regards, dezet. ...Show All

• Visual Studio 2008 (Pre-release) WPF - Forcing software rendering for multi-threaded rendering (multi-core advantage)

  Here is a good one for the experts (especially the WPF team): Consider a scenario such as this. 1. A control needs to be rendered and stored as a bitmap thousands of times. 2. Each rendering will be different, and all images will be saved. 3. Since each rendering is made to be independant, the control and all data can be created on its own thread, which allows multiple renderings to occur at the same time. Thus performance is improved significantly for multi-core systems. I already have such a system/design where this works using .NET 2.0 and winforms (GDI+). Since GDI+ uses the CPU, everything is great, I see a 70% performance increase for each additional core. However, since WPF will attempt to use hardware rendering, I assum ...Show All

• Smart Device Development Enabling num Lock programatically

  I am writing a program for a PocketPC that has a built-in keyboard using eVC, and I was wondering if there was a way to activate the number/symbol lock key programatically As it is, the user has to push the orange key on the keyboard twice to enable the locking feature, I would prefer to be able to enable it in my program so all the user has to do is type the numbers.

• SQL Server Company Dimension

  We deal with multiple vendors who provide us information via text/xml files. Vendor A may provide financial data, vendor b provides litigation data, vendor c provides ratings data. Our current structure has databases for each vendor with its own company table which basically makes all this data disconnected. Of course each vendor has its own proprietary company id to make records unique. All of the data is based on companies so the grain of data would be at a company level. I would like to be able to link this information together by creating a dimensional model that has a single company table (DimCompany) and has facts populated based on the type of data we receive. Would this be the right sequence of events 1. My initial load (h ...Show All

• .NET Development Run .NET executable over the network

  What do I need to do to run a VB .NET executable over the network I have written a simple VB .net program. It works fine when executed locally, but simply will not run when executed over the network. For example, when connecting to the folder via the UNC path (Start -> Run \\ServerName\ShareName ), and then doubleclicking on the executable in the Debug or Release folder, the mouse changes to a wait icon for a second or two and then returns to normal. The program never runs. Event logs don't show any log entries related to this program. Several google searches have hinted at security (that's why I'm posting here). I've granted full Control to Everyone to the Share and Full Control to Everyone for NTFS (it's a test environment), ...Show All
