    - Marshal.GetLastWin32Error errors Hello, I have a problem with Marshal.GetLastWin32Error() Every call returns 127 (ERROR_PROC_NOT_FOUND) even if the previous call = was successful. For example, given: namespace Utils { public class Win32 { [DllImport("user32.dll", SetLastError =3D true)] public static extern IntPtr FindWindow(string lpClassName, = string lpWindowName); } } And this code: int rc; IntPtr hwnd =3D Win32.FindWindow("something", "something else"); rc =3D Marshal.GetLastWin32Error(); The call to FindWindow() succeeds (hwnd gets a non-null value) but Marshal.GetLastWin32Error() returns 127. What am I doing wrong? Thanks, Alex. Tag: SystemEvents TimeChanged in Windows Service Tag: 92696

    - com object with CLSID{...} is either not valid or not registered Hi I have VB.net that faxes text docs. On the production test machine I get the error shown below when it trys to FAX. I suspect I am missing a library ref but don't know what. The develoment machine has Office installed, the production test machine does not. The project appeared to deploy correctly in that Interop assemblies for FAXCOMlib, OfficeCore and Word were placed in the application directory. The CLSID mentioned below seems to show up in a number of queries on Google but I have been unable to track down an answer. Any ideas? Thanks Bob 4/03/2005 3:05:13 p.m. clsFaxer.SendFax COM object with CLSID {000209FF-0000-0000-C000-000000000046} is either not valid or not registered.

    - COMException and Multiple Threads My VB.NET application spins up a secondary GUI thread. This thread hosts a Custom User Control (which owns the window handle) and some COM objects which interact with a Third Party Application. When a method call to one of the COM objects results in an error, the .NET Interop throws a System.Runtime.InteropServices.COMException, as one would expect. However, while generating this exception, both the main and secondary GUI threads are halted. I can find no explanation for why the main thread should halt during this time. The entire purpose of spinning up a secondary GUI thread was to allow the primary GUI thread to stay active while COM related processing was occurring. Does anyone know what is happening under the covers of the COM Interop that would cause this? This pause (of about three seconds) only occurs when the first COMException is thrown. Subsequent exceptions do not cause the entire application to halt. Thanks, MP Tag: SystemEvents TimeChanged in Windows Service Tag: 92671

    - Successive calls to ResourceManager.GetObject The behavior of ResourceManager.GetObject concerns me. Logically, successive calls to ResourceManager.GetObject with the same resource name should return the same resource. That is, the following code should return true: Object a = resourceManager.GetObject("resourceName"); Object b = resourceManager.GetObject("resourceName"); return object.ReferenceEquals(a, b); Reading through the decompiled code with reflector indicates to me that this is how it is intended to work, but when I try the above, false is returned. It appears the ResourceManger and ResourceSet classes work as follows: Calling ResourceManager.GetObject looks through resource sets from most to least specific, loading and caching them when needed. Each resource set in sequence looks for an object in its internal hash table by loading and caching the table when queried. With the exception of ResourceManager.ReleaseAllResources (which isn't called internally), I see no code involved with clearing these caches. Is this a bug? Or is this behavior intended? If it is intended, why? And where/when is the cache cleared? Thank you, Brandon Bloom Tag: SystemEvents TimeChanged in Windows Service Tag: 92667

    - Threads freezes other application I have a C# application that runs fine on any computer (XP, 2000, 98). I have just installed on a PC that also has a POS which runs in kiosk mode. The problem is that when my application start running the POS stop responding (or at least stop repainting screens). My application is a console application which starts 2 different threads. I debugged my application and found out that on thread #1 the line of code affecting the POS is a Thread.Sleep(x); on thread #2 the line is a Monitor.Wait(x). If I remove those lines from code the POS works fine, but my application will not work as intended. I'm suspicious of the [STAThread] attribute on the Main function. I will appreciate any kind of help. Tag: SystemEvents TimeChanged in Windows Service Tag: 92645

    - events and threading Hi there, i have an object O1 in a thread context C1. This object BeginInvokes() a loop-oriented method M2 on a second object O2 thereby creating a new thread context C2 for O2.M2. O1 has before registered on an event eventually fired by O2.M2. This eventually results in executing the handler function O1.H1 on thread context C2. This is not thread safe without some provision. Can i force the execution thread of the handler O1.H1 back to C1 as it is done by Control.BeginInvoke(). The event firing in O2.M2 is done using some construction like handler.BeginInvoke() but i suppose this doesnt help.

    - HttpWebRequest and headers with only newline Is there any way I can get the HttpWebRequest object to accept headers with only \n in them? When I go towards a particular url I get a ProtocolViolation error when the headers in the received data only has \n to separate the fields. If I make me a proxy and intercept the packets and change the \n to \r\n it works just fine. It seems to me that it's a bit strict to assume \r\n on http headers. The same code works fine under Mono, so guess the Unix guys are a bit more "forgiving" on these issues since \n is more unix like. It's a bit hackish in my opinion to implement a proxy in order to get this to work. If anyone want the example url feel free to contact me. -m Tag: SystemEvents TimeChanged in Windows Service Tag: 92638

There are frequent (usually too frequent) informational or debugging messages. Database and files. Lots of different stuff. What is the Microsoft recommended solution? LIAB?

    - Custom Controls in VB.NET and NetMeeting Desktop Share Hi!!!! I have an odd problem with VB.NET: I created a stand-alone application with some custom controls on it. I also added some code to add a nice border to it. The application works fine in the user's computer. However, when I show it through NetMeeting (by sharing the desktop), the custom control does not appear correctly in the remote computers: the border I did with "DrawRectangle" sometimes is missing. Something similar happened to me when I did another application where I draw directly into a PictureBox control: The custom drawing appears correctly in the user's computer, but it doesn't show in NetMeeting when I share the desktop. I solved this last bug by putting a label control right on it... although I must mention that I'm not exactly sure that was the most adequate solution.

    - ExecuteReader() not firing exceptions from stored procedures, also HasRows() vs Read() Hi All, We're using the 1.1. Framework against SQL Server 2000, and are having a strange issue where we don't get errors back from the stored procedure, i.e. the exception never gets thrown. The scenario is this: 1.) Set up SqlConnection and SqlCommand 2.) Set SqlDataReader equal to the return value from SqlCommand.ExecuteReader 3.) Check SqlDataReader.HasRows() to see if there is any data in the stream If we do these things, but do not call SqlDataReader.Read(), we never get any exceptions from the stored procedure. Our understanding was that you want to check SqlDataReader.HasRows() before doing anything, in case there was no data returned. This apparently does not work. The mysterious part is why the exception does not fire on step #2 (SqlCommand.ExecuteReader() ). We use SqlDataReader objects to stream stored procedure results back when we have a smallrowsets. Normally, our code looks like so: '...set up connection and command... rdr = cmd.ExecuteReader While rdr.Read 'Process row... Loop 'et cetera... In this case, the exception fires normally. However, one of our developers tried: If rdr.HasRows Then While rdr.Read 'Process row.. Loop End If This results in the total suppression of SQL Server errors that occurred in the stored procedure. Why does this occur? Of what use is HasRows() if it doesn't throw the exceptions that are apparently waiting in the SqlDataReader stream? Are there any other "scenarios" we should be aware of which would suppress the SQL Exceptions? This is scary. Here is the necessary repro information: /*SQL Server 2000*/ USE Northwind GO IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = object_id(N'[dbo].[ADOTest]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) DROP TABLE [dbo].[ADOTest] GO IF EXISTS (SELECT * from dbo.sysobjects WHERE id = object_id(N'[dbo].[selADOTest]') and OBJECTPROPERTY(id, N'IsProcedure') = 1) DROP PROCEDURE [dbo].[selADOTest] GO CREATE TABLE ADOTest ( DateVal varchar(19) NOT NULL ) GO INSERT INTO ADOTest (DateVal) VALUES ('2005-02-2811:55.000') GO CREATE PROCEDURE dbo.selADOTest AS SET NOCOUNT ON SELECT CONVERT(datetime, DateVal) AS DateVal FROM ADOTest GO GRANT EXECUTE ON selADOTest TO public GO 'VB.Net: (Paste code into the click event of a button on a Windows Form): Dim conn As System.Data.SqlClient.SqlConnection, cmd As System.Data.SqlClient.SqlCommand, rdr As System.Data.SqlClient.SqlDataReader Dim hasRows As Boolean Try conn = New System.Data.SqlClient.SqlConnection("SERVER=DEV;DATABASE=Northwind;Integrated Security=SSPI;") conn.Open() cmd = conn.CreateCommand cmd.CommandType = CommandType.StoredProcedure cmd.CommandText = "dbo.selADOTest" rdr = cmd.ExecuteReader If rdr.HasRows Then While rdr.Read Debug.WriteLine(rdr("DateVal")) End While End If MsgBox("Successfully executed stored procedure.")

I'm currently having a problem with a socket. I can see in netstat that it is still in use even after the application that allocated it is done executing. Any suggestions (that work) ?

    - dispose of shared object instance How do I dispose of a shared object instance only once--after all consumers of it have been disposed of? More detail: I have a VB.NET trace class that I invoke as a shared instance in the business code I'm interested in logging. The trace class needs to close out of the file when I'm done using the business objects--but since many objects may be using it, I don't want to close the trace file before everyone has had a chance to use it. for example: '----------.dll/server-side component Public Class business_class Implements IDisposable Shared log_trace as New Trace_class Public Sub SampleMethod() Trace.WriteLine("starting SampleMethod") '... End Sub Public Sub Dispose() Implements IDisposable.Dispose log_trace.Dispose End Sub End Class '----------client-side component Public Sub Main() Dim my_business as Business_class Dim your_business as Business_class my_business.SampleMethod your_business.SampleMethod my_business.Dispose() 'the problem here is that it shouldn't yet call log_trace.Dispose my_business = Nothing your_business.Dispose() your_business = Nothing End Sub Tag: SystemEvents TimeChanged in Windows Service Tag: 92578

    - Neutral culture issues Hi, I'm getting a problem where the exception detailed below is being thrown. The winapp is not using culture or resource files in any way. If I reference the assembly (Microsoft.ApplicationBlocks.ExceptionManagement), then the exception is thrown. If I compile the same assembly on my machine (without any code change) and then reference the same assembly, then everything is OK. Whilst this is a temporary work around, deploying the application will be a nightmare as I can't compile the assembly on each and every target machine! Has anyone come across this problem before and if so, what's the resolution? I would really like to understand this one as it's very confusing! Thanks in advance! Rob An unhandled exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll Additional information: Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly.

The program and the smtp server are on two different machines. The problem could be on smtp server? How can I fix the problem?

    - Need Help regarding design time drag-drop event Hi, Can anybody tell me about any event that is invoked when a component is dropped onto a form or other root component from the 'toolbox' at design time in the VS.net, apart from the ComponentAdding/ComponentAdded events? I don't want to use them as they are called again and again when the application is build/rebuild. Regards, Deepak Tag: SystemEvents TimeChanged in Windows Service Tag: 92572

    - Pooling problems with Enterprise Service and ADO.NET Hi, I have experience with COM+, ADO, object polling and enlist distributed transactions. Now I want to create the same behavior in .NET. I use the Construct method to create and open an OleDbConnection to a Microsoft SQL Server. The autoenlistment is switch off in the connectionstring "Enlist=False". The enlist and unenlist of the distributed transaction in the Activate and Deactivate methods works smooth. In the finalize method I close the OleDbConnection. The object pool is set to min=2 and max=5. The CanBePooled method returns with true. If a client create the obejct theConstruct method is called. OK!!! If a client release the object the Finalize method is called. Fail??? The problem is, that the CanBePooled method is not called and the construct method is called again. The CanBePooled method is not called until a "DoWork" method e. g. is called. After this call the pooling works as expected and the finalize method isn't called. I don't know why the CanBePooled method isn't called until any other method is called from the object. I think, if the object is released by the client it must return immediately into the object pool. Best regards Michael. Tag: SystemEvents TimeChanged in Windows Service Tag: 92571

    - XmlSerializer exception with tag property Hi community! Perhaps someone can explain this behaviour: I have a reduced the problem to a very simple class, only having a public property Prop and a public property named Tag: [Serializable] public class C1 { public C1() {} private int _prop; private object _tag; public int Prop { get { return _prop; } set { _prop = value; } } public object Tag { get { return _tag; } set { _tag = value; } } } When I assign an int to Tag, serializing an instance of this class with an XmlSerializer works fine. When I assign an int[] to Tag, XmlSerializer throws an InvalidOperationException during serialization, saying that System.Int32[] cannot be used in this context. When I change the type of Prop from int to int[], then both cases (with int AND int[] assigned to Tag) work. How can that be? And is there a way to secure the serialization of such a class (if the value assigned to Tag is serializable, of course)? Thanks in advance, Martin MÃ¼ller Tag: SystemEvents TimeChanged in Windows Service Tag: 92570

I've been doing some googling without success.

Does anyone have any ideas of detecting if the time was changed from a
Windows Service that cannot interact with the desktop? This elminates
using the SystemEvent.TimeChanged event.

I need react when daylight saving time kicks in or someone changes the
date/time or windows calls its time server.

Is there a way of telling why the time was changed? Distinguis between
daylight savings vs user vs time server?

Thanks,
Post.

There is an option on the Properties of a Windows Service to allow it to
interact with the desktop. Once this is set it will work for you.
