• SQL Server couldn't see some of the database in the object explorer window of Management Studio

  hey guys, I have one question. But it is not related with the Reporting Service. I got my computer set up with SQL Server 2005 version yesterday. When I connect to the database engine, I can see only system databases(master,model,msdb and tempdb) under the system database folder. I couldn't see other databases(like pubs,northwind) in the object explorer window of Management Studio. Do you have any idea how to solve this difficulty Thanks. Amde Hi, no problem there. These databases aren’t installed by default. There are scripts to build up the database from scratch: http://www.microsoft.com/downl ...Show All

• Windows Live Developer Forums For Future Contests

  If there are going to be future contests like this (and there should, as they rock!), please consider the following remarks/suggestions :) - Teams: Some people like to work in teams, and this usually gets quite nice results too. However, with the current prize set-up, it's rather difficult to work in teams because who gets the prize I suggest you either give out money (:P) or split it up in multiple prizes per app (have like something slightly bigger for the team leader, and 5 smaller items for the other members, take a look at counterstrike clan contests, I believe they have a system like that) - Examples: Have some example code or links fo ...Show All

• Microsoft ISV Community Center Forums Office Accelerator

  I have been asked to implement Office Accelerator for Recruiting - which is like a ton of bricks to me because I am not sure where to start. After combing through MS web sites and stuff it seems to me that the Accelerator is a framework that implements (as far as UI) a Sharepoint or Portal solution. The solution is "not an out of the box" and uses templates, guidelines, fragments... ... from exposed MS code developed in C# using XML (taking advantage of the .NET framework). So, although my semantics may be a bit off, if I am correct in the above then I suppose the next steps would be a) Learn how to program with the Sha ...Show All

• Smart Device Development Porting WORKING MFC Application and depricated classes

  I am trying rather unsuccessfully to port a WORKING eVC4 MFC application to VS2005 under the Mobile 5.0 SDK. It would appear that microsoft has dropped some classes from support in the latest version of MFC. The two that are hitting me the hardest right now are CSplitterWnd and CEditView though I assume the CDumpContext is going to come around to be pretty troublesome as well. Are there replacement classes that we are supposed to use, or are we supposed to rewrite MFC ourselves to make this work Has anyone successfully overcome these issues that would care to share some strategies Hi, It is true that some of the classes h ...Show All

• Smart Device Development Compatibility issues VS2005 & VS2003

  Hi all, I have developed an application with VS2003, c#, for Pocket PC 2003 device.  It is using SQLCE and a lot of listViews and graphic toolbars.  Now I have a new Pocket with Windows Mobile 5.0, and my application doesn’t work.  I tryed to migrate it to Visual Studio 2005 but I have problems with datatypes (number to string formats) and display (my forms look smallest, button's graphics desapears). Please advice!!!   Do you mean your VS 2003 application does not work on WM 5.0 device as is or you're having problems after upgrading your project to VS 2005 If you've upgrad ...Show All

• Smart Device Development Missing assembly information in converted project

  This is a rather weird 'bug'. We upgraded a VS2003 Pocket PC project to VS2005. The conversion process didn't change AssemblyInfo.cs and when we go into the new Assembly Information screen in the project properties we see the settings as we set it. When we change it in that property screen, it does change in AssemblyInfo and vice versa. But when we build the project and have a look at the properties of the executable there is no version info at all. Within the same solution we have a normal desktop application and a pocket pc class library project. Both those projects were converted as well, but on the executable and DLL it builds ther ...Show All

• .NET Development IDisposable Interface - disposing managed and unmanaged resources

  Hi! I'm using VS2005 beta 2 and VB. I would like some help on understanding what is the correct way to use the IDisposble interface. After adding the Implements statement, some code is automatically added in the class. In the Dispose(boolean) method, there are two sections to dispose managed and unmanaged resources. Q1) If a file is opened using one of the System.IO classes, is it considered a managed or unmanaged resource Should I close the file in the managed or unmanaged dispose section Q2) When should I call the dispose method And if so, should I set the instance of my object to nothing Q3) When is Finilize method called Q4) If I hav ...Show All

• SQL Server How To Avoid Table Scan

  Hello All, Is their any way I can avoid a Table Scan by modifying the follow WHERE clause WHERE tbl_mis_Dashboard.loan_active_flg = 1 AND [tbl_mis_Dashboard].[loan_create_dt] between DATEADD(dd, DATEDIFF(dd,0,dateadd(mm,-13,getdate())), 0) And getdate() The field loan_create_dt is indexed on the table tbl_mis_Dashboard. The query returns approximately 256K records which is appropriate and necessary. Thanks all, Orlanzo It's hard to say, since we don't know what data is in the table or what columns you're selecting (that's just as important as what's being used in the WHERE clause).  You might ...Show All
