• Commerce Server Puget Sound area recovering from severe wind and rain storm. Responses are delayed.

  Hi all, Redmond and surrounding areas were hit bad by the recent storm. This is the 2nd day after the storm and there are still wide spread power outages that impacted a large number of the population. The storm impacted: Power (still out in many areas) Cable service (TV, Internet, and Phone dependent on cable service are consequently out) Streets (trees downed in many areas blocked streets preventing travel) As of this time, Redmond city power was just starting to be restored. Some outlying areas may take as long as 5-6 days to have power restored. Please excuse us, while we recover from the storm responses will be delayed. Thanks, Caesar. ...Show All

• Visual C# Fast searching of a byte array

  Can anyone provide guidance on what would be the fastest method of searching a large byte array for some particular sequence of bytes I know I could convert it to a string and do an IndexOf but I would like to avoid that. Any ideas if you were looking for the bytes 03 02 01 in the following array: 01 01 02 02 03 03 03 02 01 01 01 02 02 02 03 03, if you sorted that array looking for (also sorted) 01 02 03 you'd now not find any matches in: 01 01 01 01 01 02 02 02 02 02 02 03 03 03 03 03 ...Show All

• Visual Basic how do I Refresh "My Computer" network drives for vb express 2005 data access

  Since windows 2000 came out there has been annoying red "X" on My Computer's network drives. If you click on them, they go away and the files are displayed. In VB 2005, the mycomputer.filesystem.drives.item(n) does not refesh them and directory.getfiles("P:\") returns an error "could not find part of the path P:\" When I double click on P: in my computer, the error goes away and I can read the files again. This is annoying becuase I write a lot of network applications. How can I implement code in my program to refresh drive "P:" I just tried : Using sw As StreamWriter = New StreamWriter( "P:\temp.log" ) That does not work also... ...Show All

• SQL Server Does "SQL Server 2005 Mobile Edition" exist?

  "SQL Server 2005 Mobile Edition" is a standalone software or it equals "SQL Server 2005" + "SQL Server 2005 Mobile Edition Device SDK" Hi Raphael, SQL Server 2005 mobile edition IS a standalone software which runs by itself on the device. The data is stored with a small footprint on the device. It's like having a server and its data on the device which u carry around. As an enterprise requirement, you can connect to a SQL Server 2005 running in your enterprise and sync your device data with the server data. I believe you can also connect to a SQL Server from your device to view and work with the server data. Regards, Amol. ...Show All

• Software Development for Windows Vista Using MXDW

  I would like to use MXDW to create XPS documents from any application. But I would like to automate the creation by automating the printing process. But when I try to do this it always comes up with the "save as" dialog box. I had the same problem using the MODI driver as well. Does anyone know how to get rid of that Any samples will be helpful. Hej Charlee, _______ > Why not writing your own XPSDrv filter driver connected to NULL port, and in your filter(Stream-In and Stream-out) you take over the job and write it into where ever you want to be. _______ do you have written such a filter on your own already and have tried out if that will work though I guess myself ...Show All

• Visual Studio Error Deploying to Vista

  I have a VS2005/VB desktop application that uses the built-in version of CR. When I run the package (msi file) on a WinXP system all goes well but when I try it on a Vista (Business) system I get a series of errors indicating that various CR related dlls could not be registered. The error returned is always something like..."c:\Program Files\Common Files\Business Objects\2.7\bin\ExportModeller.dll failed to register. HRESULT -2147010895" Do I need to do something different in VS to support Vista Failing to register usually means lack of permissions to the registry. Make sure you are logged in as administrator to the machine. I have not used Vista personally, but I have heard that the permissions, especially to the reg ...Show All

• Software Development for Windows Vista Using the WF rules engine editor

  Hello there, I am working on a project where I am using the WF rules engine frequently. I have a set of rules that need to be implemented into the WF rules engine. But when I was implementing the rules into the rules editor (the dialog that came along with the WF) I found a problem. I need to write a rule like.. if ( ifCondition ) DoSomeWorks(); else if (elseIfCondition) DoSomeOtherWorks(); else DoDefaultWorks(); But I am facing trouble inserting this rule. the dialog does not allow me to insert the else if part. If I break down the else if part to another if-else group then the it will be too complicated when I have a long if-else if-else if- else if -....else chain. one more thing I found that the rule ...Show All

• Visual Studio 2008 (Pre-release) Extending DataContext?

  Is it or will it be possible to override the internals of the DataContext I want to alter the object creation implementation in the datacontext to create subclass proxies instead of just instancing the entity types directly. However DataContext seems very black boxish. Im well aware of the claims that non virtuals execute faster than virtual methods etc.. but in this kind of scenario where big chunks of data is fetched from some sort of datasource , those few nano seconds will be impossible to notice.. so that will hardly be a valid argument. Ive seen that there is a "services" collection inside the datacontext , but that also seems impossible to access from the outside. it would be really really lovely if such things were expo ...Show All

• Windows Forms DataGridView Binding to a complex Type

  Hi, I am trying to create a DataGridView which binds to a Generic Collection of my Business Object 'Application'. The business object 'Application' contains simple properties like 'Application Date' (DateTime), 'ApplicationID' (Integer), 'ApplicationType' (String) etc., but also has a property called 'Advisor' (of Type 'Employee' - which is an object within my Business Logic Layer) Now, the 'Employee' object contains properties like FullName (string), DOB etc. The problem i have is that i am binding the DataGridView To a collection of Type 'Application' like so - dgvApplications.DataSource = col_Applications (a collection of Type 'Application'). This works fine for the simple properties like 'ApplicationDate', 'ApplicationType' ...Show All

• Visual C++ Uniquely identify a printer

  I succeeded getting the settings for a printer. (a copy of the devmode). I want to store these settings to a file for later use. Since, as I know, I can use only the name of the printer as a unique identifier for a printer, I store in the file the name of the printer along with its settings. But if someone changes the name of the printer(in Printer and Faxes for exmple), the new name of the printer and the old name stored in the file along with its settings, will differ. So, I will not be able to get from the file the saved settings for the printer because its name has changed. I would need another unique identifier for the printer, a unique identifier that cannot be changed. I would save this unique identifier to the file instea ...Show All
