• .NET Development SENS Events in .NET 2.0

  I have discovered how to catch SENS events using .NET 1.1, and recently found out that .NET 2.0 will raise similar SENS events.  Unfortunately, these events that 2.0 raises do not provide as much information as what I can get from SENS directly. I will be providing links to both my local documentation, as well as the online WinFX documentation on the http://winfx.msdn.microsoft.com/library/  website in regards to the following questions. With the SystemEvents class in the Microsoft.Win32 namespace, longhorn: http://winfx.msdn.microsoft.com/library/en-us/cpref/winfx/ref/ns/microsoft.win32/c/systemevents/systemevents.asp frame=true l ...Show All

• .NET Development Problems reading array in struct

  Hi, I'm trying to marshal the DS_SELECTION_LIST struct ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/ad/ad/ds_selection_list.asp ) to C#. It works, but only the first element is retrieved. I believe this is because the marshaler can not determine the array size. However, the field cItems in the struct determines the array size. But I can not use the SizeParamIndex with UnmanagedType.ByValArray. So I tried the UnmanagedType.LPArray but then I receive the exception: System.TypeLoadException: Cannot marshal field 'aDsSelection' of type 'ADHelper.DS_SELECTION_LIST': Invalid managed/unmanaged type combination (Arrays field ...Show All

• Visual C# Implement "file download" in C#

  Hi... I am writing an application where I have a button. When the user clicks the button, data is read from a database and a text report is generated.

• Visual Studio MSBuild "Configuration" and "OutDir" Properties

  Hi! We have a preliminary MSBuild script that calls a solution to compile a ASP.NET 2.0 project like so: <MSBuild Projects="WebApp1.sln" Properties="Configuration=Release;OutDir=../webapp1_deploy/"/> We're pretty new to MSBuild so bear with us, but how does MSBuild know to interpret the "Properties" From what we can gather, - Configuration=Release tells the solution file to use 'Release.AspNetCompiler.Debug="false"; ' and - OutDir=../webapp1_deploy/ tells the solution file to set 'Release.AspNetCompiler.TargetPath="../webapp1_deploy/" ' Is there a listing of possib ...Show All

• SQL Server Data Source / ODBC error

  Hi all, My replication of those SQL 2000 servers gave errors: Data source (11): General Network Error. Check your network documentation... and ODBC (08S01): Communication link failure. The replication was across the WAN. I don't know where to start to troubleshoot this problem. Please help! Thanks in advance.

• Visual C# "taskbar notification"

  I'd like to use a "taskbar notification" in one of my apps. What I mean is that I'd like to have one of those little message boxes that look like tooltips (yellow background) slide up from the taskbar, stay up for a few seconds, then slide back down. I've seen them referred to as taskbar notifications, but they probably have a different name in the VC#/.NET. If anyone knows what they are called and how to use them, I'd appreciate knowing about it. Thanks, Jay Hello Jay. You cam use NotifyIcon control for this purpose. Just drag that from the Toolbox window to ur form. Setup the property. ...Show All

• Windows Forms listbox bound to a datatable

  I have a "mover" form (two listboxes - lstCodes (list of possible values), and lstSelected (list of selected values)) When I choose something in lstCodes, I lookup the value in a datatable dtCategoryLookup, then I populate lstSelected's datasource with a new row containing the id and description of the lookup. lstSelected is to a datatable dtSelected. When I run the code below, the only thing added to lstSelected is the string "System.Data.DataRowView" DataRow[] dr = dtCategoryLookup.Select("id='"+lstCodes.SelectedValue.ToString().Trim()+"'"); DataRow oRow = dtSelected.NewRow(); oRow["id"]=( string )dr[0]["id"]; oRow["cDescription" ...Show All

• .NET Development Strange connection string persistence issue

  I’m connecting to a MySQL database using a third party component (MySQLDirect).   The issue I’m having does not seem to be a bug in the third party component as no other users are reporting issues with it and they seem unable to help.   I would really appreciate if someone could give me some inspiration on how else I can think about tracking this issue down.   The weird issue is:   I have my MySQL database connection string in the app.config file.   I’m using the MySQLDirect components in a component designer using VB.Net 2005.   When I change the database name in the config file to another database, t ...Show All

• SQL Server autonomous transactions

  Is there any equivalent to Oracle's autonomous transaction in sqlserver. No. There is no way to do this in SQL Server right now. You can write extended SPs or CLR SPs (SQL 2005) that performs a different connection to the database. But this approach has it's own limitations and scalability problems. One workaround that will work in SQL2000/2005 depending on your requirements is to use a table variable within a transaction to dump the information. Table variables do not participate in user transactions so you can later retrieve the rows and dump them into an error log table for example after the transaction h ...Show All

• Visual Studio 2008 (Pre-release) How to get Count in GroupBy

  I tried to translate the very common sql query Select Category, count(*) as NumberOfProducts from Products group by Category into linq syntax. I was able to write it like this: var orderGroups = from p in products group p by p.Category into g select new { Category = g.Key, NumberOfProducts = g.Count() }; Question: is there a O(1) way, to get the NumberOfProducts without using the Count()-Function running presumably O(n) Thanks! Depending on the underlying server, which in all of our cases at the moment, is SQL 2005 - Counting the number of rows in a group is actually a O(1) operation. It has a fixed cost because ...Show All
