• Visual Studio Express Editions Snipets ??

  Hiya, I was wondering if anyone could help me. I am very very new to visual basic (just going through the first tutorial in my book :) Its telling me to use snipets to add code in, which is fine, but i have noticed that when i put snipets in its only putting in a few lines of code, compared with the pictures in the book there should be alot more. At first i thought it might be because I have a different revision of VB than the one used in the book, but when testing it my programme is not working so i guess i am missing code :( Is there any setting's I need to change It's possible that the book was written using a beta version of the software: the snippet they used may have changed for a final ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed DirectX Render Loop

  I'm sure this question has been asked a million times, but what is the current thinking about the best render loop for Managed DirectX I found an article on Rick Hoskinson's blog where he suggests overriding WndProc (http://blogs.msdn.com/rickhos/archive/2005/03/30/403952.aspx) and claims it's more efficient than the commonly used DoEvents and Application.Idle methods but I recently downloaded the April 2006 SDK and notice that the samples still use DoEvents. Also I tried using the WndProc method in a game of mine and noticed that in windowed mode it doesn't 'play nicely' with other windows apps, dragging the window for example is very unresponsive. Is it worth using multi-threading for the game loop to maintain responsiveness in windowed ...Show All

• SQL Server Setup of SQL 2005

  Im about to upgrade all our SQL 2000 Servers to 2005 In your setups do you install the anlaysis services, reporting services on separate servers rather than all on the same server. Currently we have separate servers for web IIS and was wondering if to install on three different servers Hi, there is no rule of thumb. YOu will have to consider, as well workload, hardware availbility (ad costs) and licences. Sure that the best thing would be to spread the SQL Server role across different servers, but that will put more administrative overhead as well as costs on you. HTH, Jens K.

• Windows Forms Modify ConnectionString

  Hi, I searched, but couldn't find an answer. Is it possible to modify a connection string at runtime This code throws an exception, not sure how to fix. string connectionString = this .txtConnectionString.Text; ConnectionStringSettingsCollection col = ConfigurationManager .ConnectionStrings; ConnectionStringSettings section = col[ "MyConnection" ]; section.ConnectionString = connectionString; The last line throws this: System.Configuration.ConfigurationErrorsException was unhandled Message="The configuration is read only." Is this something I can configure I have a requirement to allow certain users the ability to change the connections string, rather than forcing them to modify the app. ...Show All

• SQL Server FTP Connection Manager: Set FTP password using a variable

  Hi, I want to setup an FTP task that is portable in the sense that all it's connection parameters are stored in variables. I can create expressions for properties ServerName and ServerUserName but not the ServerUserpassword.  Is there an property that I missed, there seems to be properties for everything else except the key piece of info, the password. I could create a script component using the FtpClientConnection method as a last resort but would rather not. Any ideas Thanks Dan,   I have tried a several combination of that example (including a period you are suggesting) but didn't get it working. It has to be sometjing else on the configuration to prevent pasing of the conne ...Show All

• Windows Forms How to copy forms from one Project to another ?

  Using C#, ADO.Net, Vis Studio 2005, SQL Server: I've got one Project using 'myDatabase'. I made another project that uses the same database. In the new project, I did the "Add->Existing" and brought in a form from the first project complete with with TabControls, etc... The files were the myForm.cs, myForm.Designer.CS, and myForm.resx. When I compile the new project, I get the following errors referencing the code in the myForm.designer.cs file: Error 1 The type name 'myDataSet' does not exist in the type 'myProject.myProject', (where the 'myProject' is the project name and namespace both.) ...and a whole bunch of lines similar to: Error 2 The type name 'myDataSetTableAdapters' does not exist in the type ' ...Show All

• Visual C# Inheritance Bugs in Windows Forms

  I'm using the Visual Studio 2005 to do WinForms development and have been repeatedly running into problems with inheritance. What happens is that sometimes when I override methods in a base class the override isn't called - but the base class method is called instead. I've verified repeatedly that the code is correct, the method signatures match, and the override should be called (polymorphically) rather than the base class method - and yet it calls the base method instead. I haven't seen in in none Form-based classes so far, but I've seen it several times in specialized Forms that I've created. In each case, the problem is the same. The base class method is invoked rather than the override method. It appears to be a bug in the compiler. N ...Show All

• Visual Studio Team System Pre-build validation failes for setup project

  Hi there, I am trying to build a setup project (.vdproj) using team build. I am aware that msbuild does not support building setup projects and one has to add custom task to build setup projects separately using devenv. I have added a custom task in TFSBuild.proj file to build the setup project. However, it fails to build it and gives an error. The command I have added is: >D:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv" $(SolutionRoot)\Setup\Setup.vdproj /Build "Release" The error it shows is something like this: ERROR: Invalid or unspecified target for shortcut <shortcutname>, ERROR: Cannot find outputs of project output group '(unable to determine name)'.

• Visual FoxPro CursorAdapters and ConnectBusy

  Hey all. I was doing some work with CursorAdapters and SQL Server and ran into the dreaded ConnectBusy issue. This was caused by having an adapter open where I guess all the data hadn't yet been pulled down so while it did a SCAN ENDSCAN with some updates, it kept coming back saying ConnectBusy and it felt like an endless loop. I got around the problem by putting in some code to ensure I could go to the top of the file and the bottom of the file and then reran my scan loop. But I know there's an easier way. What are some of you doing to get around this I know about a few of the approaches but I know there must be some other better ones around there. Thanks I just tried this out and think this may be a good way to go. My datamanager ...Show All
