• .NET Development new to .net web service, deploy problem

  I'm newbie of .Net web service. I developed a simple web service demo and published as DemoWSEcho under \Inetpub\wwwroot. And in the directory of DemoWSEcho, i have a Service.asmx , a PrecompiledApp.config, a folder named bin with App_Code.compiled and App_Code.dll in it. The Service.asmx file only contains one line of code: <%@ WebService Language="C#" CodeBehind="~/App_Code/Service.cs" Class="Service" %> And i want to publish the web service on another machine, as far as i can understand, i just need to copy the whole folder DemoWSEcho to wwwroot directory of the other machine which has IIS installed. But when i access http://localhost/DemoWSEcho/service.asmx on the other machine, i see nothing but a l ...Show All

  hi all, I am developing an application using WPF and i want to let the user check his email in one of the wpf forms.

• Visual Basic hiding the startup form

  Hi, I was wondering if there is a way to immediately hide the startup form on startup. The Me.visible = False and Me.hide() Methods don't work. I am trying to make a simple program that has a login form and the main form. When my program starts i want the login screen to appear and the main form to immediately disappear, then when the user clicks OK the login screen closes and the main form shows. Everything works except when the program runs both the login and the main form window appear and i can't seem to make the main form disappear, and for other reasons setting the login form as the startup form is not an option. Hope this is a simple fix. Connor SJWhiteley, I read through your post and i was kinda c ...Show All

• Visual Studio Team System Bug - UI crash & Build fails without errors or warnings

  This is related to http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=848718&SiteID=1 but now I can reproduce the other error (project does not build) and it goes off topic, for that reason I'm starting a new thread. In the previous thread I (several other threads indicate this problem too) reached a state where it was no longer possible to build or deploy the project. In this state there were / are no errors or warnings when an attempt was made to build. I have found that this occurs when a file is deleted from the project and for some reason the project file is not updated to reflect the deletion. In this case it was a crash of the IDE caused by being to quick changing the focus after a delete. On restart the IDE did indicat ...Show All

• Windows Forms FixedToolWindow Locked

  It's my understand that the locked property should prevent the user from moving a child window. With this property the user is still able to adjust the location of the FixedToolWindow. Is there any property or event I should be setting to prevent this Some developers have suggested setting the window border style to none and then adding a label as the window title, but thought I would see if a better solution exists. Thanks in advance. The Dock property is just like the Locked property; it is inherited from the Control class but makes no sense for the Form class. Forms don't know how to dock themselves since they don't have a container. ...Show All

• Visual Studio Express Editions IDE Font not going bold...

  Hey all, I'm trying to make the font for the IDE Text Editor to be bold for more clarity on my new larger monitor. I go Tools -> Options -> Fonts & Colours -> Text Editor (drop down) and check the box marked Bold. I hit OK and restart just to make sure, but the only thing that has changed is that now the parenthesis and braces are bold, but the text remains the same. Any ideas Failing a solution to that, can anyone recommend a good mono-spaced font that's already thick Something like a FixedSys only larger That's my favourite font and would love an 11 or 12 point version (I tried the TTF version that's available, but it looks like *** when resized up). Well thanks. A very nice fixed pitch ...Show All

• Visual Studio 2008 (Pre-release) MSMQ WCF - multiple readers for the queue

  Hi! What would be proper way to control WCF service reading from MSMQ one message at a time Our solution requires multiple readers to read from single queue to provide scalability. Ideally each of the services would read and process one message at a time without reading any in the buffer before they can actually process it. We found out that ServiceHost.ManualFlowControlLimit and IncrementManualFlowControlLimit() get us almost there, but not quite as the service seems to read always one message to the "buffer" before stalling the process. That is; if the ManualFlowControlLimit gets to 0, the service is not going to process messages before it is incremented, but it does read one message from the MSMQ regardless. Th ...Show All

• Windows Forms How to search treeNode object in TreeView?

  Hi there, I have an issue with TreeView Form controler, I would like to know if there is a way (and i'm sure there is) to search and "get" a trrenode from the treeView by the node name - string. My need is to add changes in existing treeView nodes that already exists and i don' know the index of each node. I write in C# and have few knowledge in .NET forms. TIA Or even easier (assuming you're using 2.0 framework)... Nodes.Find("some node name", true); //true for search children, false otherwise Returns an array of TreeNodes. Steve ...Show All

• SQL Server Prediction Query for a "weighted" clustering model

  I have a question about writing a prediction query against a clustering model that has the same column added more than once. Per Jamie, I can accomplish some crude weighting by adding a column to my model multiple times. See this post for an explnation... Now that I have that worked out, I was wondering how my DM query would look If I have Input_A1, Input_A2 , & Input_A3 all being source from the same column in my structure do I have to reference all three when writing my prediction query to be most theoretically accurate, yes, however, I would check to see how the results change for your particular model as you change inputs. If you don't have any missing data, it may not make a significant difference. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. OpenGL performance in 2.0

  I am trying to use .NET 2.0 with an application that draws and object with ~70.000 triangles. It is ok in the VS2003, it renders immediately, but now with the VS2005 I have to wait 7 seconds to have the object rendered! I am still using CSGL.dll, .NET1.1 version. Is there any performance problem I read it should run correctly in the loaded 2.0 Framework. I suspect that somewhere in then OpenGL wrapper there is some interop going on that causes huge slowdowns just like the Texture.FromBitmap in Managed DirectX. See http://www.thezbuffer.com/articles/401.aspx There are some workarounds in the bug, and hopefully this will be fixed in an upcoming VS service pack (no idea on any release date sorry) ...Show All

• Architecture What is the most valuable principle in design?

  In looking at SOA, earlier component based design, separation of concerns, etc. It seems to me that architecturally they can all be lumped in to various flavors of abstraction. So, it occurs to me and seems to hold true in my designs that the most valuable principle in software design is abstraction. Does anyone feel that a different principle is more critical Are there different schools of thought (SOA, SOC, Interface based design, etc.) that are contradictory when dealing with abstraction New to the forum, but have been wanting to talk with people that make an effort to further their design knowledge. For me, principles are really situationally specific. I think what is more fundamental is axioms that ...Show All
