• Smart Device Development unable to connect to pocket pc device(dell axim x5) from visual studio though activesync 3.8 is up,running and connected

  Hi all, I have installed MS-Activesync 3.8 and it shows the status as "connected" and synchronized(when my dell axim x5 is docked in its cradle which in turn is connected to my pc via a USB cable. The pocket pc OS version=4). I'm even able to synchronize files between my desktop and the handheld.

Be sure the device is physically connected to the development computer" (though the activesync icon is in green ...Show All

• Visual C# Protected Override code

  I have just started playing with the RC of VS2005, In the current project I need to Override the OnPaint Event of the windows form. When I did this in the Beta 2 system, it produced the override and added an exception to the code. Now when I try it in RC it adds the following "base.OnPaint(e)". Now the question I have is does this need to be in the code block if I am going to be providing the override code Do I leave it there, and Add my code to the event With the last comment about leaving it there, where do I put my code so that the over ride works correclty. Do I put it above the base call, or below. Obviously, it depends on if yo ...Show All

• SQL Server SMO Method Performance

  I've run a series of performance tests on a test app that uses smo for creating sql server tables (including columns, indexes, triggers, and foreign keys) and stored procedures (including parameters). On a 2.7GHz machine with 512MB ram (both app and Sql Server running locally), the series of tests yielded the following results: Table.Create() 0.3 ==> 0.6 seconds PrimaryKeyIndex.Create() 0.7 ==> 0.9 seconds Trigger.Create() ~0.06 seconds StoredProcedure.Create() 0.12 ==> 0.14 seconds With creating a large number of tables/indexes/stored procedures in the app, I'm concerned about performance. Are there ways to quicke ...Show All

• Visual Basic Access The Result Of A Function Called In A Splash Screen

  Hi, My application currently has three classes - MainForm.vb, SplashScreen.vb and a user-created class Server.vb. In the latter class, I have a function which pings a server (at the moment I'm just using the Google IP as I will get a "True" result). When my splash screen is shown, the function is called so the user is informed if the server can be reached. What I want to do is access the result of this function in my MainForm load event (at the moment I'm just using a Button click event) without having to call the function again. I've tried putting a public variable in my MainForm.vb class which the splash screen changes according ...Show All

• .NET Development Exposing a class to remoting

  Hey everybody! I just started getting into .NET Remoting about a week ago, and have began to really understand the power behind it and am currently working on exposing a data-accessing component I have created as a remote object.  I have about 6 objects that all do similar data-accessing functionality therefore all inherit from one abstract class which does most of the 'common' work.   I would like to expose these 6 objects to be run on a remote server. I have choosen to expose these objects from Singleton activation mode (i.e. not SingleCall) which ensures that at most one copy of each of these classes are made and execu ...Show All

• Windows Forms Autoscroll

  When I use AutoScroll, scrollbars never show up if the controls are outside of the container to the left or top of it, only to the right or bottom. How do I fix this Yes you can access autoscrollbars by using p/invokes to the Windows Shell functions. Check this link: http://msdn.microsoft.com/library/default.asp url=/library/en-us/shellcc/platform/commctls/scrollbars/scrollbarreference/scrollbarfunctions/setscrollinfo.asp But this is not something you need to do know. Still you might want to check my post on richtextbox & autoscrollbars to see a sample on how it works: http://forums.microsof ...Show All

• SQL Server Controlling PDF export filename

  Folks, Our client has requested that we change the export file name (PDF and others) to match the report name. Currently, the name is based on the report's filename (eg, foo.rdl exports as foo.pdf) -- this causes problems because the same RDL is being used for a few fairly different reports. Is this controllable at all thanks, --randy If you are using the ReportViewer control, you can set the DisplayName property. This will affect the export file name and the document map root node label. If you are using direct url access to the report server, the name can't be changed. In that ...Show All

• Visual Studio Team System Cannot browse any site!!

NO userid passes this test and I get an error page (I have installed the VSTS on a Windows Domain Controller and created the necessary users for setup/service and reports as mentioned in the installation guide.)

• Visual Studio 2008 (Pre-release) How to find namespaces/Objects that are "out of date" ?

  Hi! When frameworks are updated some namespaces change there content, are removed etc.. is there a good site where you can find in which namespace your object are in the actual framework, but the definition you have is in an old version.. that maybe sounded strange but here’s an example.. I’m reading an article from Jan 2005 about the object UITimer in the System.Threading At that time .NET v1.2 something was the deal, but now with .NET 2.0 there is not such an object with that specific name.. has the object been removed,replaced, renamed When i google on this specific object I only find out of date data from the .NET 1.2 era, nothing like ...Show All
