• Visual Studio 2008 (Pre-release) DLINQ & Remoting; LINQ over Active Directory

  1. Does DLINQ supports remoting What will happen if I'll pass DLINQ entity out of application domain via remoting 2. I'm interested in using of LINQ to perform queries over active directory database. Any suggestion Bart De Smet has an excellent series of articles on building an LDAP provider for LINQ, which you might find useful: http://community.bartdesmet.net/blogs/bart/archive/2007/04/05/the-iqueryable-tales-linq-to-ldap-part-0.aspx Of course, it's not production-quality (his words), but it's a great series on how one might go about creating a provider. ...Show All

• Windows Forms File Encryption?

  In my windows form application I want to develop a method to protect my text file contents from being seen by anyone. I am storing a username and password in the text file. I tried Encrypting the file, but then it cannot be modified by the user if they want to change their password or username. Or does anyone have any other suggestions as to where and how I can store a username and password that is not directly accessable via a text editor Basically, the concept of serialization is reading in a supposidly known chunk of data, and then parsing that data to whatever/whereever it belongs. If you are, for example, reading in a database record, you could call that "concept" serialization. Same thing when you read in your text f ...Show All

• Smart Device Development Debug multithreaded application on WinCE 5.0 with VS 2005

  Hi, I have a multithreaded C++ application. When I break into one of the threads, I want to see the call stack of that thread and all the other threads. This works fine, except when the thread is blocked in the WinCE kernel. For these threads, I don't get a call stack, just a single address within the kernel. At the MEDC I got the suggestion to try to load the symbols for coredll.dll, but that didn't help. How should I go about getting the results I need Antonie Bosch Security Systems. Antonie, The above is a limitation of system calls. To illustrate the same if you had replaced the above code with some thing like below you would see the call stack. /*WaitForSingleObject(hThread1, ...Show All

• SQL Server SQL Server 2005 SP1 Failure

  My upgrade to SP1 for SQL Server 2005 failed and I have yet to find a reason or a solution. I have read many articles describing file security problems, registry problems etc. I have been through these and looked at all of the different aspects and still cannot find a fix other than to unistall SQL and reinstall SQL. Since this is a production server and is used 24/7 I would rather avoid this. The installation is on a windows 2003 server with SP1 that was upgraded from Windows 2000. SQL was originally installed fresh on 2000. There is 21GB of HD space left.

• Visual C++ Problems with delay-loading DLLs

  Hi. I have a DLL module.dll and I want my application to use delay-loading. The idea is that the module may be missing and the app should detect that and continue with limited functionality. I'm using the example from here: http://msdn2.microsoft.com/en-US/library/8yfshtha.aspx However I'm seeing 2 problems: 1) The __HrLoadAllImportsForDll function uses memcmp instead of stricmp to compare the argument with the list of delay-loadable modules. It turns out the string in the table is "module.DLL". So how do I know in advance what is the correct case Is it guaranteed to be that, or can it sometimes be "Module.dll", "MODULE.DLL", or something else Where does the case come from 2) Contrary to the exa ...Show All

• SQL Server Ordering data in SQL EE by VB

  How I can ordering data in SQL EE by VB 2005 EE. Thanks. So what exactly is the problem Are you asking if this works This is the T-SQL forum, so the most that most of us can tell you is that: SELECT Meno, Skore, Cas, Rychlost, Datum FROM Table1 ORDER BY Skore Seems a relatively valid SQL statement, as long as you have a table named Table1 (which you hopefully don't) and the other columns listed exist. Otherwise we can move the thread to a VB forum ...Show All

• Software Development for Windows Vista Activity instances

  What is the instance model for instances - how does it work in a workflow How long do instances last, when torn down It seems I can ref instance in simple seq workflow (i.e. this.MyActivity1.SomePublicProperty) and refer to it properties to get some last run data. But when I put the activity in a while activity, the same property is null as if it did not run, but it did. TIA --wjs Check out these two posts by Nate Talbert. They should give you the information you need on the instance model, as well as the issue you are running into, which has to do with spawned contexts. http://blogs.msdn.com/advancedworkflow/archive/2006/03/21/557121.aspx http://blogs.msdn.com/advancedworkflow/archive/2006/02 ...Show All

• Commerce Server Expanding the RegionCodes table

  Hi I am trying to expand the RegionCodes table to include a tax rate. The problem I have is that even in the underlying DataRow properties of the RegionCodeDataSet.StateCodesRow class my new column is not being retrieved. I have tried looking for a stored procedure that retrieves from the RegionCodes table but there isn't one in the transactionconfig database. Could somebody tell me firstly whether it is possible to expand this table, and providing it is possible how the data is retrieved Regards Paul Tew The dataset exposed for the regioncodes table does not take the extensibility into account. You should write your own code to access the new columns. ...Show All

• Visual Studio 100% CPU Usage Problem with Crystal XI R2 and .Net 2.0

  **Using Visual Studio 2005 and Crystal Reports XI Release 2 Developer Edition. I currently have a multi-threaded C# application that loads a Crystal Report at runtime, fills out the necessary parameters and then exports the file to disk. I export around 5000 reports a day, in about 3 hours (nightly runs of the day's transactions), but sometimes, without warning or any debug info, the application locks-up using 100% of the processor and becomes completely unresponsive. No more reports are loaded or exported. ***It is soo unresponsive that if i actually click 'PAUSE' in visual studio, my processor continues to use 100% of the cpu.*** (only time I have ever seen this) I know Crystal Reports has some legacy COM objects, and I have been doing r ...Show All
