• Windows Networking Development Questions of qWave API

  When I call API QOSCreateHandle, the return is true. However, When API QOSStartTrackingClient is called. the return is false and GetLastError returns error code 1168, which says ERROR_NOT_FOUND. My environment is Vista OS build5472.winmain_idx01.060713-1900 with platform SDK of version 6.0.5472.2.1.WindowsSDK_Vista_idw.DVD.Rel.img Thanks for any help... chunkai, one of the reasons ERROR_NOT_FOUND would be returned is if the destination address you specified could not be reached from your local adapter. Is the address you're attempting to track on the local subnet thx. Mathias ...Show All

• Windows Forms Redirecting a new Application request to an existing Process

  In .NET, I want to make it so my App can only run one instance at a time. But rather than just showing an error message that another instance is already running, I want to set the focus on the existing one. Better yet, if I double-click on a data file (which automatically loads the app and loads the file), I want to set focus on my App and load the datafile that was selected. I know that many standard applications do this. Any ideas on how Thanks! -Nathan Thanks, that helps alot. As for passing any arguments to the original app, such as the file to load, I'm thinking of making a registry key that my program would check for, using a timer, and have the newly loaded app set the registry key, set focus ...Show All

• Windows Forms add 2 DataTables into 1 DataGrid

  hi, I have 2 dataadapters that fills 2 datatables i want to show them both in 1 datagrid How do i do it I think detail steps to combine two tables depend on the logic how you want to combine them. If you just want to create a new table with all columns in those original two tables, use following code for example DataTable dt = new DataTable(); foreach (DataColumn column in northwindDataSet.Customers.Columns) dt.Columns.Add( new DataColumn(column.ColumnName,column.DataType,column.Expression)); foreach (DataColumn column in northwindDataSet.Employees.Columns) { if (dt.Columns.Contains(column.ColumnName)) continue ; dt.Columns.Add( new DataColum ...Show All

• Software Development for Windows Vista Both Client and Server Hosted Workflows in Single Tracking Store

  We are creating a new application and would like to use Workflow Foundation as a fundamental aspect. We know we want to use server based workflows and we are considering client based workflows as well. We envision client based workflows primarily for managing UI aspects such screens to be displayed, as we don't want to manage this from the server due to lag times. My question has to do with how to have a centralized workflow management/tracking system that includes workflow instance information from all clients as well as the server based workflows. We foresee the need to reassign client workflows or to monitor abnormally terminated client workflows through this centralized tracking system (we would need to include persisted workflows as w ...Show All

• Visual Studio 2008 (Pre-release) Item Activation in ListView

  Hi, I was hoping for some kind of ItemActivated event in the ListView class, but cannot see one. I want to be able to detect users double-clicking or otherwise activating an item in the list view. What is the simplest way to achieve this I tried the ListView.MouseDoubleClicked event but that of course fires anywhere in the ListView. There is the ListViewItem.MouseDoubleClicked event but that only works for double-clicking, not for pressing enter on a selected item. Thanks, Kent Boogaart Seconded, I need this as well, except for a TreeView. I've tried doing this manually with MouseDoubleClick and KeyDown Style/EventSetters and attached handlers but both have their problems -- event setters fire ...Show All

• SQL Server Query timeout

  I need to figure out if my query is timing out due to row lock contention. The SqlException trapped in my client C# application contains Error Number 1205 but sometimes it contains -2. I guess the SqlCommand timeout and the server timeout are the two possibilities. Is there a definitive way to find out that the SqlException was thrown due to one of these two reasons Because if it's some other reason, I want to excute a different logic. Thanks, Madhav MadhavG wrote: The deadlocking behavior is not accidental, it's part of my application logic. I am not sure I understand.

• Visual Studio Express Editions Calculate Emailaddress from multiple textboxes.

  Hi, I'm totally new to programming in VB but you have to start somewhere! It's so cool! What I'm trying to archieve for now is creating an emailaddress based on various input textboxes: FirstName, MiddleName, LastName. The emailaddress should be calculated like this: <1st letter of FirstName>.<MiddleName>.<LastName>@company.com If a user has no MiddleName there shouldn't be an extra dot! The EmailAddress textbox should be generated as you type the FirstName, MiddleName and LastName textboxes. I'm also looking for some tips for input validation. It should only be possible to use alphabetical characters. An additional Initials textbox should only use alphabetical characters and dots e.g. T.K.B. All help ...Show All
