• SQL Server Difference Between Physical IOs and Read-Ahead

  Hello ... I was running a table scan query on a 650MB table w/ 1 million rows.  With statistics IO and time I noticed that I was able to get the following numbers on SQL Server 2005 (note this was the Sept CTP): Logical IOs: 76,931 Physical IOs: 0 Read-Ahead: 58,321 CPU Time: 1212 ms Clock Time: 42946 ms So, in looking at the above I'm not seeing any physical IOs, but a lot of "read-ahead" IOs.  If I understand it from the docs, a read-ahead essentially moves a data page into the cache.  I understand this may mean getting a larger IO block size.  Does this mean that I'm in fact doing physical IOs ...Show All

• Visual Studio VSS Complete path for linked files.

  Using VSS 6.0, when I look at Properties, Links, I see $/.../<end of filepath> Is there any way to display the entire filepath in this view I tried creating a report and it outputs the same $/.../<end of filepath. Thanks. Keywords: -- VSS, SourceSafe, Links, File, Path, filepath, folders, display, properties. -- VSS 2005 will now create a shared file list output file that lists all link files in your database.  Product Support at microsoft has a power tool called vssems that has the option to display link files.  You can call up and they (I) will send it out to you. ...Show All

• Visual Studio Tools for Office Automation executable consumes 100% CPU

  Hello!!! I have developed and automation executable to druve Excel and I'm poretty happy with it apart from the fact that it consumes 100% of the CPU while it's running - even when the app should really be idling. The problem is caused by this piece of code while (close == false ) System.Windows.Forms. Application .DoEvents(); I got this pattern from my VSTO book ( )and it's abviously going to cause the CPU hogging that I'm experiencing. Where can I find a better pattern for automation executables TIA, Doug What VSTO book are you using Thanks! Mike Hernan ...Show All

• Visual Studio Adding menus items (don't understand ProvideMenuResourceAttribute)

  I'm taking the normal ToolWindow sample and modifying it to start a new package. This package simply exposes menu items and nothing else. I modified all of the commands and guids and names and stuff and now I'm not seeing my menus showing up as I expected them to. There is only one thing that I don't feel I've changed correctly (though this may not be the true problem) because I dont understand the numbers its using. At the top of the ToolWindow sample the attribute is added to the package class. MSVSIP.ProvideMenuResource(1000, 1) Now I believe I understand that this attribute is mostly there so the VSIPRegPkg utility can generate the corr ...Show All

• Windows Forms Dynamically loading MDIchild forms at runtime

  Hi all, I would like to create an application where i can easily add / update components (e.g. inventory component, customers component) to the application without modifying the main project. I tried to design the architecture based on a MDI-application where I define the components in MDIchilds. The MDI-parent is then the main project. Each MDI-child has to be registered in a database and subsequently based on a user's credentials, this MDI-child can be loaded. Also based on these credentials, the user menu is dynamically created. I am actually looking for a project similar to DotNetNuke, but then developed in Windows Forms... But th ...Show All

• Visual Basic F1 Doesn't Search Online Help

  I'm new to using VB 2005 Express 8.0.50727.42; previously I have only used VBA for OfficeXP (VB6, it seems).  Fresh install of VB and Ihave not installed the optional MDS Express Library. When I press F1 on a built-in function in my code, lets say 'left()', I get the all too familiar screen: "You have chosen to use local Help only for Search and F1 results, and the topic could not be found in local Help.  This error can be caused when..."

• .NET Development XML and dataset question

  Hi all, I've posted this already on the VB express forum, but I didn't get an answer. This might be a better forum for my question: I've created a DataSet and use xml-files as my database. The principle is outlined in this article: http://www.devx.com/dotnet/Article/28678 So for every DataTable I have an XML-file containing the data for that table. If the dataset contains a lot of tables I also get a lot of XML-files that way. I've found examples of reading/writing the complete dataset in one file and reading/writing datatables on a per file basis. Now I wonder: Is it possible to store multiple tables of a DataSet in o ...Show All
