• Windows Forms DragDrop to MonthCalendar control

  I'm writing a little scheduling application. Basically, I want to be able to drag drop items on the monthCalendar control. This works just fine. But I want to be able to drop them on a specific day on the calendar. I can tell the X,Y position from the DragOver event, but how do I translate that into the actual day they are dropping it on Or is there a better way MonthCalendar has the HitTest() method to find out where the mouse is located. It is however rather crude, you can just find out what area of the calendar you're on, not what date. So, I thought of a trick: fool the control into believing that the user clicked with the mouse. Then you can simply look at the SelectionStart property to find the date. Here's a simple Windows F ...Show All

• Visual Studio August 2006 V3 RTM ???

• SQL Server T-SQL question

  I have some T-SQL experience and can do most basic stuff fairly easily. I've been tasked with generating a report that compares 2 different numbers in 2 tables. The join query that I wrote works well, but now they have asked me for a subset of the data returned. Basically my result set give me a format similiar to the following. Bob, Jim 000000012345 0012345 Doe, Jane 000001234567,1234567 If the second number returned has zeros preceding the number i need to include those in the report, and exclude ones that do not. I am unfamiliar with how to sort that, i am familiar with using trim to specify the number of spaces on the left or right to trim. Can i use a sub-query, or would i use a cursor to do this ...Show All

• Windows Forms DataGridView Search

  Hi I am using a DataGridView for a timeline - there is a time column starting at 00:00:00.0. I also got a timeslider (Trackbar). When I use the timeslider the correct row in the DataGridView should be selected/highlighted.. Therefore, when using the timeslider the application needs to search the DataGridView for a certain time string. What is the best way to do this Thank you Thank you for answering. The number of timeslider values is not equal to the number of DataGridView rows - so I need to search the DataGridView for a specific time value. ...Show All

• SQL Server Using many-many relationship in SSAS

  Hi, we have built a cube implementing many-many relationship within. will it have any effect on the performance if a many-many relationship is used within a cube with large volumes of data I have implemented a cube with about 3 dimensions referenced through many-to-many relationships. I have a fair bit of data and I wouldn't say there is a considerable effect in performance if you define your aggregations properly. However if you can add this dimension as extra attributes of another dimension I would advise you to do so. ...Show All

• .NET Development .NET (v2.0.50727) server committed a protocol violation

  Hi, I’m working on a simple web service in C# running on IIS which sends a GET-Request to an external server. The Get-Request is received properly and processed by the external server. A trace with Network Monitor tells me that the response code from the external server is 202-Accepted. I guess this might cause the problem that the HttpWebResponse class throws the following WebException “ The server committed a protocol violation. Section=ResponseStatusLine” I looked at many mailing lists and found the ( httpWebRequest useUnsafeHeaderParsing="true" ) patch. I changed machine.config and web.config but without any changes. I also changed the header field “connection” in the Get-Request from “keep-a ...Show All

• Visual Studio 2008 (Pre-release) Root object(class) in Domain Object Model

  I have a question, the question is: In the ADO.NET vNext Entity Data Framework how do I solve the problem of having a root object in my domain model Let's say in my domain object model I have to have a root class from where every other class will be inherited. Obviously the root class does not need to be persisted, it simply adds some behavior to all the objects that I am going to use in my application. While playing with the August CTP, I noticed that I could not make this work. Maybe I'm missing something. Maybe there are ways to get around this problem, can anyone please shed some lights on it I replied to the other thread here: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=70336 ...Show All

• SQL Server Wrong Set Option during request with serverside cursor

  Hi, I'm working with VB5, ADO 2.7 and SQL Server 2005 and want to retrieve some data from a table with a lot of rows using a serverside cursor. The table has a computed column and so I need to set arithabort on, which I set after opening the connection. While I'm looping through the Recordset, I need to execute some statements, which use a user defined function (scalar), where I can't set the set option arithabort. My problem is, after opening the serverside cursor, the value of arithabort is off (and not on!). In Profiler, each time I execute a command while the cursor is open, there is an Audit Logout and Audit Login. Audit Login changes the set option for arithabort to off (maybe because of ADO or the database default set ...Show All
