• SQL Server SQL Server 2005 Express CPU usage too high??

  I have a website with about 130,000 page views per day, I'm using a P4 2.8G/1GB RAM dedicated server for database. When I upgraded my database to SQL Server 2005 Express, I noticed the CPU usage goes too high, sometimes the CPU usage goes to 100%. My database table only has about 25K records. My questions is how to optimize my database Is there any tips to do that start by getting a trace profile to see which statements are taking up the most time in terms of Duration, CPU and Reads. Then look at the plan. ...Show All

• Visual Studio 2008 (Pre-release) dynamic layout of forms

  hi everyone, im curious if there is a way of having forms dynamically built in the Presentation Foundation. Having general code that is used to build up many forms, through an automation of some kind. Is this possible Cesar You might want to look at the Composite UI Application Block (CAB) for another solution. There is a lot of similarity within the two frameworks. You could write an application that reads a database and generates XAML or it could Generate the WPF elements dynamically. With a bit of thought you could create a database schema that tells the application what kind of UI element each table and/or field in a tabl ...Show All

• Software Development for Windows Vista Custom HandleExternalEventActivity ParameterBindings problem

  It's better then in Beta 1, where interfaceType- and EventName properties "disappeared" when creating a custom EventSink. Even though they don't disappear anymore, I still loose the ability to set the ParameterBindings in the property window ... Is there a workaround, except for adding them manually wmmihaa, On a generic HandleExternalEventActivity you can still bind to the external data event args parameter and then use it as needed. On a strongly typed, wca-generated HandleExternalEventActivity, the individual parameters should still appear. Arjun ...Show All

• Visual FoxPro WinSock

  I just tried Microsoft WinSock OLE Control 6.0 (SP4). It binds to a port and it goes into a LISTEN state but I cannot figure out how to unbind the connection. Close() method does not work, SendComplete() does not work either I do not know why Other methods do not seem to be relevant. Does anyone have any experience with WinSock Thanks. I don't have any experience with Winsock as I don't use it, but maybe these Wiki entries may be of help: http://fox.wikis.com/wc.dll Wiki~WinSockOCXSample http://fox.wikis.com/wc.dll Wiki~WinSockOCX~WIN_COM_API   ...Show All

• Windows Forms Databound ComboBox with space for selecting None

  Hello everybody, I am trying to build a search form for a new application I am building.  The form has a couple of text fields and some comboBoxes for narrowing search criteria.  My comboBoxes are all databound to show valid values from the database.  The problem is that I would like to have the option of not selecting a value in the comboBoxes. For example suppose I'm building an inventory system: search form has fields Asset#, Description, Make, Model, Supplier. Make, Model, Supplier are databound comboBoxes with valid values from the database. In this situation in order to find and asset I would have to select the appropri ...Show All

• Visual C# Array lookup

  If I create an array int[] siteid = {38, 55, 102, 176}; Is there any way to programmatically determine if the value 38 is one of the elements, without iterating through each element Is there a way to do an array lookup in C# Hi, I don't think so, but if you can, use a hashtable and then you can do what you asked for. Edit: I was thinking in terms of accessing an object (in this case, an int) in O(1) time, that is, access it directly without any time performance problem (in constant time). Since IndexOf does the loop for you, it will take O(n) (depends on the number of elements in the array). With an hashtable the time is O(1) (normal ...Show All

• Visual Basic Upgrading from vb6: Dim as New is VERY different

  In Vb6, Dim myvar as New MyType would check whether myvar was Nothing at each reference and reinitialise it if neessary. Obviously this isnt the case with Vb.NET, and if the variable has been set to Nothing in the mean time then it will have a value of nothing causing an exception. Anybody got any clever ways of resolving this one (there are quite a lot of instances of this in the app I have been asked to upgrade) You could create a generic method like the following (available only in the 2.0 Framework). This method takes a variable of any type and initializes it if said variable has no reference; otherwise it just returns that ...Show All

• Visual C# Changing the Default Unhandled Exception Dialog

  Hi Everyone, Is it possible for me to customize the default dialog that pops up when .NET encounters an unhandled exception Thank you. I spoke too soon..Your answer seems partially right -- probably I am missing something obvious since I'm new to .NET. The approach you described allowed me to add a new UnhandledExcepionEventHandler that responds to uncaught exceptions but I was unable to un-hook the default handler that displays the dialog window. So, basically, there were two handlers in place. Because AppDomain.CurrentDomain.UnhandledException is an event, I am only able to add handlers to it ...Show All

• Windows Forms Why is there no CaptionText in the DataGridView Control?

  Hi Folks, this is a question to Mark Rideout (or anyone from MS): Why was the CaptionText property not migrated from the old DataGrid control to the new DataGridView control Is there a replacement or do we have to create a user control combining a DataGridView and a Label Thanks. We talked with some customers and got the impression that it isn't a needed feature as UI's were getting more graphical and more "office-like". We left it up to app developers to combine and style things as they saw fit for their app. -mark DataGridView Program Manager Microsoft This post is provided "as-is" ...Show All
