• Software Development for Windows Vista Device Cannot Start (Code 10) in Vista, worked fine in XP

  I've looked through lots of documents in MSDN, but have not found where to go for further information. It is a USB Driver made by someone who left the company, and we are looking to see what needs to be modified for Vista32 (not 64). Anyone know where to start for information on the differences in the drivers. I read http://www.microsoft.com/whdc/devtools/wdk/drvcompat_vista.mspx but that doesnt seem to address our problem. The answer is out there, soemwhere... Hi CatcJake : Did you find something about this I'm having the same issue and I'm completely stuck.

• SQL Server Deserialize ACL problem

  I'm developing a custom security extension to Reporting services. In my authorization class I have a problem to deserialize the ACL (secDesc parameter). I have many examples and I’m doing the same excepted for one thing I’m not in form authentication but I’m in windows authentication. The problem is in the method 'DeserializeAcl(byte[] ...)'. I encounter this kind of bug : BinaryFormatter versions incompatibility : Excpected version 1.0, received version 880850475.24252454. Thanx for your help Sorry but no. We stopped working on windows authentication with the extension. I designed the solution with using form authentication which is well documented. Eric ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Device is being used by a thread other than the creation thread.

  Hi, My engine design is to create the Dx device and manage lost devices on the same thread, and to handle all resources operations and draw calls on another one. The application is responsible for all synchronizations between the two threads and ensure that no race condition could occur. Given that, D3DCREATE_MULTITHREADED flag is not needed because resources are always created, locked and used on the same single thread. So why is DirectX debug version sending me few warning messages "Device is being used by a thread other than the creation thread" on every Dx calls Is there something wrong in my design Thanks Guillaume >>A warning is just that, a warning. I totally agree. The ...Show All

• Visual Studio Tools for Office Insert HTML to a Rich Text Content Control

  Is there a way for the Rich text Control to load and handle HTML. I'm told that rich text should handle the HTML and allow it to be edited. Word accepts only plain text or its internal XML as direct input. For everything else you need a conversion filter; conversion filters are triggered only when inserting a file or pasting from the Clipboard. Both approaches are available to you as methods through the object model's Range and Selection objects. There is no way to "drop" HTML into a Word document's RichText control, nor extract it as HTML. What would be possible is to use a transform to / from WordProcessingML, Word's native XML language. ...Show All

• Visual Studio Team System Pinpointing string concatenation with profiler

  I have a specific problem that I cant seem to be able to resolve. I have inherited a big (200+ pages) asp.net 1.1 project in a bad shape. Performance counters indicate high CPU, big allocated bytes/sec, high % in GC and a lot of Gen2 collections. I have ported the project to .net2.0 and ran a few profiles on it (in both sampling and instrumental) and have found that about 50% of all allocated memory goes to String type and almost no activity in LOH (2 strings in total), so my first diagnosis is small strings concatenation abuse :) Now this is what I cant seem to do is to create a call graph to + and += operators of string type, as looking for those in 200+ pages will be a nightmare, so any idea would be appreciated. I tried to resolv ...Show All

When i run the MDX query in the query editor it displays correct results. but when i execute the MDX query in the program it also return the top levels of the dimension hierarchy.

Region(top),Country(Middle), and Reporting Unit(Lowest). The user wants to see Country info by selecting countries as DK,GB,US. This is the query to execute. In MDX query analyzer it gives proper output. SELECT NON EMPTY {{[Meas ...Show All

• Visual Basic What Events will be Triggered on Load

"0 1") Enter Focus to First control for user input (ensures needed things are entered first KeyDown Validate Key Pressed (KeyCode) - For Custom Mask TextChanged Strore Data into variables Leave Validate input as a whole But sometimes these events are triggered on load and they cause errors, and they waste resources. Also i noticed (when i insert Break Points & run,) that the events are triggered a few times before completing, this causes the form to fliker (i think).

• Smart Device Development Cinternet Session MFC VS 2005 SP1 Beta- Strange behaviour

  Hi I recently upgraded to VS 2005 SP1 and is using the MFC CHttpConnection API. I had to compile the .exe program with a Static MFC lib as the current hardware device does not have the updated MFC libraries. OK. Here is how I am doing the tests. 1) Complete Hardreset of the winmobile 2005 device/emulator 2) copy the release version of the app to \ 3) perform the necessary setups 4) run the app. The App connects to the internet to download a file from my web server.

• Visual C# Retrieve column names using metadata

  I am implementing an application that needs to quickly retrieve a list of column names of a table for an ODBC connection. Is there a way to use metadata to achieve the goal so that I don't need to run a query on the entire table Thanks. Hi, If you're using table adapters and dataset you can call the table adapter's FillShema method on the table you're interrested in. Next you just have to iterate on the table's column: DataSet ds = new DataSet (); ds . Tables . Add ( "MyTable" );   OdbcConnection conn = new OdbcConnection ( connString );   OdbcDataAdapter adapter = new OdbcDataAdapter (); adapter . SelectCommand = new Odbc Command (     &nb ...Show All
