    - How to make UI proof middle tier? While we still wait for a real "Application Browser" to be made there is still the decision whether to target the web client platform or the smart client platform and no good answer. No technology is in more of a state of flux than this. Think about it. We have clunky 'web 2.0'. Big companies pulling at the web in different directions and could come out with a new fangle platform overnight. WinForms being replaced by WPF. P&P making the Composite UI Application Block and then are replacing it with Acropolis. From an architects perspective I want to keep all of this as far away from my 'core code' as possible. However you P&P guys don't help me do that. And in your own architectures you seem to commit the middle tier to one or the other. The middle tier I'm referring to is the "Work Controller" it's the object that controls nitty gritty state of the application. With P&P you commit to the Web Client SoftwareFactory or Composite UI Application Block and in future, Acropolis. It's not rocket science to access the database through WCF services. And I can do my multi step transaction processing in Windows WorkFlow. And my model, a typed DataSet does a decent job as a transport between the view and the services. The step that is still tied to the UI is the Work Controller and my command handling code. Could the same Work Controller DLL be pushed to the client in a smart client scenario or kept back on a server in a web scenario Obviously bindings would be setup different with WCF however it seems like it could be possible. What about agile development of a web site After initial development is done in plain Web Forms and usability tests show what UI is too clunky and needs short cut keys, drag and drop etc. a Silverlight form or separate smart client utility could be used to target areas of a web application to streamline, eg Spreadsheet grid, or a invoice receipt form. Can the same Work Controller be used equally well between an ASP.NET web form and the WPF page So why doesn't P&P create an architecture that fits all Can such a pattern not be created with out creating something that can do everything but does nothing well Tag: Architecture General Redesign of "Two" Systems.

    - WDS is slowing down System Performance Hi guys I’m hoping you can help me I already posted on http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=1111995&SiteID=1&mode=1 but thought that this would be the better forum to post this too. The user I am working with has WDS installed but is having quite a bit of performance issues and this is a newly bought and installed desktop. When we look at task manager it is the searchindexer.exe that is taking up all of the CPU power and disk writes. The user has Windows XP and Office 2003 I checked the client’s computer and currently he does not have any anti-virus or backup software installed but he does have running in the system tray and startup VNC server, Trillian, HotSync, Adobe Photo Downloader, Virtual Drive, Robo Form and Bear Scheduler. The searchindexer.exe process continues to eat up CPU and drive writes and when we end task on that exe the PC runs ok but the user really wants to run WDS so a uninstall is not a option he would like to take. We have re-installed WDS but that did not resolve the problem. I have found these 2 errors in his application log ******************************* Event Type: Error Event Source: Windows Search Service Event Category: Gatherer Event ID: 3102 Date: 1/8/2007 Time: 2:43:17 PM User: N/A Computer: ROB-DESKTOP Description: The per-user filter pool for session 0 could not be added.

    - Vista-to-Vista WDS Not Querying Remote Index I have two systems on a LAN, one running Vista Ultimate and a laptop runing Home Premium. I have an entire data drive on the main (Ultimate) system indexed, and shared. However, on the laptop, when opening that share from Network Places and running a search, search is brutally slow and notes "Network locations and connected devices are indexed more slowly..." I thought that Desktop Search would query the remote index when doing Vista-to-Vista searches. However, this appears not to be happening here (although I don't know how I'd know for sure... except for the incredible slowness and that notice.) I'd rather not use the UNC path add-in if I can avoid it. Does anyone know: That Vista Home Premium - to - Vista Ultimate desktop searches will query remote indexes What the requirements are for this to happen successfully I have file sharing on and have full control with the account I'm using.

    - Problem configuring a custom protocol handler on Vista RC1 I have developed a hierarchical custom search protocol handler, which I have been trying to integrate with Windows Search on Vista. The steps I've taken to register the handler are: 1. Create a REG_SZ value under HKLM/Software/Microsoft/Windows Search/ProtocolHandlers. The MSN WDS Toolbar documentation mentions an AddProtocol method that can be called on the SearchManager, but this does not exist in the ISearchManager interface in Vista (see searchapi.h in the SDK), so given the lack of documentation for alternatives I've registered the key directly. 2. Use ISearchCrawlScopeManager to add a search root and default scope. The search root is created with IsHierchical = TRUE and FollowDirectories = TRUE. The registration itself completes successfully and I have confirmed new registry keys/values were added under the ProtocolHandler and CrawlScopeManager keys. After registration I rebuilt the index and have confirmed that the search indexer loads my protocol handler and successfully calls the ISearchProtocol::Init method, which returns S_OK. However, the indexer never calls CreateAccessor. At this point I really don't know what is failing, but I suspect it has something to do with how the search root and/or scope rule were defined, or that some other additional configuration step is needed. Here is a summary of the settings that are added to the registry: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\CrawlScopeManager\Windows\SystemIndex\SearchRoots\3] "URL"="XYZ://12345/" "Schedule"="" "IsHierarchical"=dword:00000001 "ProvidesNotifications"=dword:00000000 "EnumerationDepth"=dword:ffffffff "HostDepth"=dword:00000000 "FollowDirectories"=dword:00000001 "AuthType"=dword:00000000 Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\CrawlScopeManager\Windows\SystemIndex\DefaultRules\12] "Default"=dword:00000001 "Include"=dword:00000001 "IncludeSubDirs"=dword:00000001 "Suppress"=dword:00000000 "URL"="XYZ://12345/" "Hierarchical"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\ProtocolHandlers] "XYZ"="Search.MyHandler.1" I would appreciate any feedback on mistakes I may have made, pointers to documentation for managing registration of protocol handlers, search roots, and scope rules on Vista, and info on how to get useful logs or other troubleshooting info out of the indexer.

    - Delaying file deletion with file adapter I have a BizTalk orchestration that uses a file adapter to monitor a directory, pick up a .wav file, rename it, build e-mail body/subject, attach the .wav file and send it to an imaging solution via e-mail and also place a copy of the .wav file in a backup directory. The BizTalk solution works like a charm when manually dropping files into the Receive Location. The problem is that the .wav files are created through third-party digital recording software that attempts to reopen the file immediately after completing the save, resulting in an error for the end user because BizTalk has already deleted the file from the directory. I have looked at the possibility of using a convoy, however, since the file is still deleted, there's the chance that it may not be back in place in time for the recording software to reopen it. Is there any way to delay the file deletion from the Receive Location (i.e. file creation timestamp + 5 minutes) Thanks! Cathy Tag: Architecture General Redesign of "Two" Systems. Architecture

    - Manually Configure URLs Hi all, I need to be able to manually "configure URLs" for documents. I'm not sure how else to word it. Basically, say I have a document "d1" which I get WDS to index. However, I would like to map d1 to URL u1, so that when I search for the document using WDS, I get back u1, and not d1. This would probably be some sort of wrapper around the index, which would perform the mapping between document ID and URL. Is there any way to do this I've looked at the documentation, and I haven't found anything that addresses this issue. Thanks in advance, -A Tag: Architecture General Redesign of "Two" Systems.

    - Win32API.FindWindowByID for a VB Application ControlID returns zero..why? Hello, There are 3 applications as given below 1. CRM Web application 2. .Net Asset Maintenance ( C# based) Software 3. Inventory Control applicaton developed in VB6.0 that I am integrating with AgentDesktop I have written three adapters for all the above so that when a new issue is created in CRM web app , it send the "Problem/Issue description" to other apps. They in turn will use the data and manipulate it. The adapter for .Net application works fine. But the VB6.0 adapter is having issues. Using spy++, I found out the ControlID (Which is 00000008). Following is the code to populate the textbox in VB app with the data it reccives public override bool DoAction(Action action, ref string data) { if (action.Name == "CreateTicket") { IntPtr txtDesc; txtDesc = Win32API.FindWindowByID(this.process.MainWindowHandle, 8); Win32API.SetWindowTextAny(txtDesc, data); } return true; } The above piece of code doesn't work at all.When I debugged I found Win32API.FindWindowByID function returns 0 (Zero).

    - Need to pass "raw" input message to SQL Adapter - how? Greetings, We are using the SQL Adapter to call a stored procedure that inserts a row in a SQL Server table. One of the table columns is of type xml . We want to pass the "raw" XML that is input through our receive port location. The schema for this location has a record named <root> with 5 elements beneath it - pretty simple stuff. We want to pass the native XML coming through the receive port to our back-end stored procedure. We need to store the original XML in the xml column for historical reference. We have mapped the <root> record to an attribute in the send port schema and set the "Source Links" property on the mapping link to "Copy text and subcontent value". This causes the text values for the 5 elements beneath <root> to be concatenated. It works in the sense that our back-end database table is being updated with the value we pass to the stored procedure but it isn't the native XML we need. How do we map the literal XML message to an output schema so that it will be passed through the SQL Adapter to a stored procedure Thanks, BCB Tag: Architecture General Redesign of "Two" Systems.
