• Software Development for Windows Vista "Allow Service to interact with desktop" does not work on Vista

  Network Instruments is using extensively "Allow Service to interact with desktop" for the application configuration. The latest build of Vista (5744) still does not support "Allow Service to interact with desktop" feature. I can see the service running and an application that it starts and tracks is also running (seen in the Task manager). Not only that, when I configure the application - running as app - and then run it from the service, it functions and I can communicate with it. However I can't see it on the desktop. Is there a fix on a way We NEED an option to allow Service to interact with desktop!!! Just a thought on this: Is there any way to show the Services desk ...Show All

• .NET Development Data Sources Window and Data Binding

  I have a question about data binding that someone may have an answer for. I'm going through "Walkthrough: Connecting to Data in a Database".  I'm using Visual Studio 2005 and SQL Server Express 2005.  I've loaded the Northwind tables etc. in SQL Server Express. The first time through this walkthrough, I created a new Windows Application project.  I opened the Data Sources window and "added a new data source".  I selected the Customers and Orders tables and let it create the dataset in my project.   I opened Form1, returned to my Data Sources window, and drug a few Customers fields and the Orders datagridview on to Form1.  Visual Studio then created the northwindDataSet, the customersBindingNavi ...Show All

• Visual Studio Team System VSDB Output file path

  I am trying to figure out the Output path of a built VSDB project. I can get the IVsOutputGroup for the “Built” configuration. and call the get_KeyOutput method. This always returns an empty string. If I have a C# project it returns the correct assembly path. Is this a BUG in VSDB Or should I get a different inferface for VSDB Thanks. ...Show All

• SQL Server Getting AutoNumber values after INSERT

  Simple question, I hope. How can I retrieve the AutoNumber generated by INSERTing a row using SqlCommand This would be the unique ID of the record and I need to perform other operations with it. Any help would be great. Thanks in advance You will want to use SCOPE_IDENTITY() "INSERT INTO table(); SELECT CAST(SCOPE_IDENTITY() AS INT)" then use the ExecuteScalar and cast it to an Int32 Int32 AutoID = (Int32) Cmd.ExecuteScalar ...Show All

• Smart Device Development How to form a bitmap image in compact framework

  hi all... i am developing an appliction in which i am drawing some rectangles & lines along with some text. I am using .NET compact framework. But whatevr application i have developed it is showing some flickering problem. So can anyone tell me how to remove this flickering. If we form a bitmap image from the rectangles, lines & text then i think we can remove this flickering. So can anybody tell me how to form a bitmap image at runtime in .NET compact framework. Thanks, vinay Exactly same way that in full .NET: Create image, create graphics object, draw and dispose. Bitmap b = new Bitmap(100, 100); Graphics g = Graphics.FromImage(b); //Draw here g.DrawElli ...Show All

• Visual Studio Need help: Graphical designer for my XML file

  Hi folks! I am a newby in this forum and this is my very first post. Our company develops a component-based framework based on .NET 2.0. For this framework, I'm currently working on a solution generator. The idea is simply that we create a processor which creates a complete VS solution from an input file which describes the application using xml. To manipulate this xml file, I want to create sort of a graphical designer (e.g. like the class designer in VS). Currently, we have only a simple TreeView to edit the xml which isn't very impressive... Thanks for your quick response! swisscklash79 Have a look at the Domain Specific Language support in VSIP (google it). It has a steep learning curve but it allows you to create designers ju ...Show All

• Visual Studio 2008 (Pre-release) Get window height, without the height of the activitybar.

  Is there any way to get the height of the visible area of a window If you just use this.Height you will get the visible height + the height of the bar at the top. You could just subtract ~25px but this height depends on what theme you use on windows so this is not a good option :/ You should always use ActualWidth/ActualHeight instead of Width/Height to determine the correct size after layout has been applied. ...Show All

• Windows Forms BindingSource , DataBindings and my own private hell!

  Hi All, Ok so I have finally decided to stop chasing my tail and ask for help! There seems to be a very big gap in my understanding of databinding and the binding source component. For the sake of brevity I will simplify the code I am using merely to get my point across : I have a master-details Dataset exposed to my UI as an object datasource ( the dataset is compiled in a separate assembly ) , I have set up a bindingsource component for each of the tables in the dataset in the form of : Private Sub Form1_Load( ByVal sender As Object , ByVal e As System.EventArgs) Handles Me .Load ' InvDs is the datset containing the master and detail datatable. iDAdapter.Fill(InvDs.InvoiceDetails) iHAdapter.Fill(InvDs.InvoiceHeader) ...Show All

• Visual Studio Express Editions listbox updated display from within vb.net

  bit new to vb.net and have a problem thats annoying me. I have a form with a button and listbox. in the buttons event i have a loop that calls a process with some parameters. the process runs until complete and then goes on to the next loop where it all repeats until the loop is complete. at the end of each process I add one of the process parameters to a listbox. This all runs well but the listbox display will not update until the button event is finished, which means all of the process calls are complete, so its an all or nothing on the listbox display. I want the listbox display to update as each process in the loop is completed. Ive tried the listbox.show and the me.show to update the form but they all do noth ...Show All

• Visual Studio Express Editions create a string from a dataset with all values from a collum seperated by commas cvs

  Ok. Here's what I'm trying to do... I've got a collum that I want to get the value from each row. The collum name is AcctName, the number of rows isn't static. I get results returned such as: Johnsons millers blakes Smiths I want to turn those into a string that's seperated by commas, so I'd have a string like: johnsons,millers,blakes,smiths I just can't figure it out, I'm still new and don't understand looping well but I think it'd need to use a stringbuilder append while looping through each row and appending the first collum item. TextBox1.Text = ds1.Tables("table").Rows(0).Item(0) - This will get the firstrow firstcollum of my dataset and put it into textbox1. My dataset name is ds1. It's the first row first collum I need to ...Show All

• Visual Studio 2008 (Pre-release) Cant' get past Connection Limit of 10 on Windows Server 2003

  We're having trouble getting past the 10 connection limit. A simple NetTcpBinding service will accept exactly 10 client connections but no more. This is using WCF RC1 on Windows Server 2003 Standard. We've set the binding's MaxConnections property to 1000. What else is needed to enable more than 10 clients to simultaneously connect to a service David Pallmann Architectural Consultant Neudesic I found the answer: in addition to setting your binding's MaxConnections setting to a reasonable value, you also have to override the default throttling settings of your ServiceHost to get more than 10 connections.

• SQL Server IN CLAUSE

  Hello, I think I'm getting something in SQL SERVER that is none sence for me at least... Example: SELECT * FROM A WHERE A.ID IN (SELECT B.ID FROM B WHERE A.NAME='ABC' ) This query is returning DATA and It works... in SQL SERVER 2000 Can I invoke an external table in a subquery that is using IN clause This is not possible in many other DBMS... I don't know if this a BUG (offcourse It's possible with an EXISTS clause but It should be possible with IN clause) You probably wouldn't feel it was such an issue if you had: where exists (select * from B where b.id = a.id) --and yet this works in exactly the same way, in every DBMS I can think of.
