• SQL Server GUID

  Hello, I'm working on a smart client app that has an offline sql express store and needs to work with several types of central databases (support for multiple products - ms sql, DB2 etc) While trying to put together some offline functionality that needs the user to create records on the offline sql express data store, we've run into the need of being able to uniquely identify records so replicating the data in the offline store back into the primary database should not be a problem. The data created offline spans many tables and involves several tables with relation ships - FK etc...Clearly not a simple case of store and forward. ...Show All

• Visual Studio Help using the Visual Studio DIA SDK for debugging...

  I’m trying to provide myself a call stack dump whenever my code causes an exception, and I want to use the DIA SDK rather than ImageHlp API. Ie I want to see the callstack when my program crashes, rather like the callstack is shown in VisualStudio, except I’m not using an out of process debugger – I want to do this in my own app. The DIA SDK provides some COM interfaces to support what I want to do, but unfortunately there is no documentation. All I know is that IDiaStackWalkerHelper and IDiaStackWalkFrame must be implemented by the client. As to exactly how, remains a mystery! And this is where you step in! Let m ...Show All

• Visual C# Visual C# Look and Feel nice in XP, ordinary in 2000, why?

  Hi, I downloaded and am running Visual C# Express on my Windows 2000 machine. At first, I was slightly taken aback by the clumsy, clunky look of some of the dialogs in the IDE itself. That is, some of the buttons were strangely large and the size of some dialogs just didn't come anywhere near the professional, smart look of say, Office 2000. For example the "Edit Rows and Columns..." dialog if you right-click on a TableLayout panel. I'm not being picky here, I'll send a screenshot when I get home - it looks quite unproportioned and particularly ugly ;-) I have 1152x864 resolution. I was guessing that it was something to do with the ...Show All

• Smart Device Development Smartphone - submenus on left softkey

  I'm creating an app for Smartphone 2003 and am having problems with the menus.  I know that, "The Designed for Windows Mobile logo certification stipulates that the left softkey is always a common default action (not a pop-up menu)."   However, I've seen plenty of Smartphone apps with submenus on both the left and right softkeys.  I'm using Visual Studio 2005 Standard, and although I thought they had dropped this restriction (from some research I did a few months back), it looks like the left softkey still doesn't support submenus.  How are people creating these fully-functioning menus when VS doesn't support it   Sh ...Show All

• Visual Studio 2008 (Pre-release) Keeping BitmapImage from using too much memory

  Scanned paper documents are usually stored as black and white (one bit pixel depth) TIFF images (TIFF Group IV 2D). TIFF is one of the native codecs supported by the WIC. The problem I'm having is a 50KB image uses 40MB of RAM when loaded in a BitmapImage for use as an Image source. So if the pages from a 12 page document are cached for quick page turning 500MB of RAM will be needed (not feasible). Typically a legal sized 300 DPI TIFF decompressed should use about 1.4 MB of memory ((8.5 x 300) x (14 x 300)) bits. I figure something should be able to be done to keep the BitmapImage at a lower pixel depth than 32bpp, thus reducing memory usage ...Show All

• SQL Server Is only "shared memory" connection with "SQL Server Management Studio Express" supported?

  I have installed MS SQL Sever Express with it there is a SQL Server Configuration Manager installed. In this configuration manager there it is possible to enable and disable protocols for SQLEXPRESS.

In the "SQL Server Management Studio Express" I connect to the SQL server and this works fine when "shared memory" are enabled. But when I disable "shared memory" in the configuration manager I can not connect to the SQL server via "SQL Server Management Studio Expres ...Show All
