Software Development for Windows Vista Tricky issue with DynamicUpdate please help!
Suppose you have a Workflow with the following Structure. <SequentialActivity> ActivityA, ActivityB </SequentialActivity> if I change this using Dynamic update to look like <SequentialActivity><MyContainerActivity>ActivityA, ActivityB <MyContainerActivity></SequentialActivity>. Achieving this using DynamicUpdate API work BUT if ActivityA or ActivityB try to access variables defined in the Workflow (Workflow State) then the workflow-level variables are null. Very tricky problem. Could you please suggest how this could be solved e.g. if ActivityA (after the dynamic update) tries to do Console.WriteLine("Show Woklfow Counter Variable {0}", counter); I get counter = null .

Visual Studio 2008 (Pre-release) Suggestions: AutoGenerating fields.
Here's something I'd like to throw out... It would be nice to specify a property to build itself if its reference is null. That is, let's say I'm creating a Location object that has an address: Location l = new Location(); l.Address = new Address(); Generally I'm a lazy programmer, and I'd like to be able to assume that Address is always a non-null value, like such: Location l = new Location(); l.Address.City = "city"; And in the getter something like this: public Address Address { get { if ( _Address == null ) {_Address = new Address(); _Address.ID = Guid.NewGuid(); } return _Address; } } Along such lines, would it also be possible to autogenerate Guids I use Guids for ...Show All
Visual Studio Full text search in Sandcastle gerated CHM files
Hi, Would'nt it be nice to add full-text search to the CHM files generated by Sandcastle I've added <xsl:text>Full-text search=Yes
</xsl:text> to the ReflectionToChmProject stylesheet transformation. That works beautifully ;-) Ideally I'd like to see this line of code move to the standard distribution of Sandcastle, because I will start to pay idiot tax on it when new versions are rolled out (and I will need to continuously re-integrate that change) What do you think, folks WetHat Hi Anand, in my opinion the increased filesize for embedded full text search is a fair tradeoff for the much improved user experience.

Visual Studio Express Editions Accessing web text box
I am making a program that automates the downloading of a file from a website of one of our providers. There is a login page which I can load up on Form1_Load() which has a user name and password box.

SQL Server Cube deployment issue SSAS 2005
Hello all, I got an issue with deploying my cube. I am new to SSAS 2005, and I cannot find the option to define which account to use with deploying. I managed to choose the server for deployment, but strangely enough, no user can be selected, so when it deploys, it throws an error stating the standard windows login isn't valid (wich is correct, but I do not want to use standard windows login). Hm, if I try to add the server to 'servers' (BIDS -> Tools -> Add server), it doesn't seem to reckognise SQL Server 2005. Though it does reckognise SQL Server 2000, wich runs on the same server. ...Show All
SQL Server Output and Error Output write the same table at the same time, stall the process.
Hi I have Lookup task to determine if source data should be updated to or insert to the customer table. After Lookup task, the Error Output pipeline will redirect to insert new data to the table and the Output pipeline will update customer table. But these two tasks will be processing at the same time which causes stall on the process. Never end..... The job is similiart to what Slow Changing Dimention does but it won't update the table at the same time. What can I do to avoid such situation Thanks in advance, JD JD Li wrote: Jamie Thomson wrote: You need to do the update and insert serially - meaning in 2 different data-flows.

Software Development for Windows Vista about ACM Wrapper filter
according to msdn docs ACM Wrapper filter is used both as decompressor filter and compressor filter. i have three questions : 1. if I use ACM Wrapper like in msdn example as compression filter , can it compress files only from PCM format or format of source file doesn't matter 2. if I use ACM Wrapper like in msdn example as compression filter , can it also perform resampling , if I change media type of its output pin 3. in order to do both format conversion and resampling of WAV files should I use ACM Wrapper to decompress WAV file to PCM , and then perform format conversion and resampling I've tried to build filter graph as follows : [file src]->[wav parser]->[acm wrapper added directly]->[format codec chosen with ICreateDevEnum ...Show All

Visual Basic Setup Wizard in VB 2005 Standard SP1
This one is aimed at Matthew Gertz in VB Development Team. Yes, I am aware that the Christmas Holidays are near but I hope your response will be quicker than last time. First two points and then my query 1. Despite ticking the Alert Me box, I am not getting Alerts when you post responses. 2. The first time, I opened VB2005 after installing SP1, I got the error message "Run Time Error/Program C:\Pro\R6025 - pure function call" and VB closed. The second time I got an Report Error toMicrosoft - which I did. Third time the programme loaded and ran OK.

SQL Server Writing to Flat File (CSV) - Duplicate Headers
I'm writing to a flat file destination (CSV file) which contains 2 header rows, lets call it Col1 and Col2. For some reason, the header rows seem to get duplicated in the output - i.e. Col1,Col2 A,B Col1,Col2 C,D Is there any way to resolve this I don't want the file to be overwritten everytime since its used for record-keeping purposes. Thanks this seems to be the result of your design; if you choose to write the header and to append to the file every time; you get what your seeing. A quick fix may be not to write the headers at all. A more elaborate one it may require to use expressions to change the properties of the destination file connection manager on such way the headers get ...Show All
Game Technologies: DirectX, XNA, XACT, etc. HLSL's tex2Dlod (Vertex Shader texture fetch) difference between PC and XBOX360?
I'm am trying to read height data from a texture to my vertex shader in XNA with tex2Dlod and I have come across a difference in setting between PC and XBOX360 and I was wondering if anyone could clarify. On my PC I can fetch data without any problems using floating point texture using SurfaceFormat.Vector4. Now just from compiler errors I know the 360 does not support Vector4 textures but Single or Vector2 are supported except that when reading from the texture I get garbage unless I use SurfaceFormat.Color. My initialization for my texture is now: #if XBOX360 planetHeightMap = new RenderTarget2D(graphicsService.GraphicsDevice, 1024, 1024, 1, SurfaceFormat.Color); #else planetHeigh ...Show All
Windows Live Developer Forums If you had it, what would you do with it?
If the Windows Live Contacts Control gave your web app programmatic access to additional information about the user or the user's selected contacts (with the user's permission, of course), what would you do with it For example, would it be useful to your web app to know whether the contacts that the user selected and sent to you were online (IM presence) If you knew a contact was online, what would your web app do with that information What kinds of "additional information" about the user or the contacts the user sends to your web app would be desirable, and why We've already heard suggestions for having access to the contact's photo, and for a unique contact ID to help correlate updates and changes.
