 - ADO >> Oracle input parameter of type string problemI created a new Web app and added a label and a button to the page.
 
 I added the following code which compiles and executes correctly and returns
 records:
 
 -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/
 
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
 System.EventArgs) Handles Button1.Click
 
 Dim OracleSelectCommand1 As System.Data.OracleClient.OracleCommand
 Dim OracleConnection1 As System.Data.OracleClient.OracleConnection
 Dim OracleDataAdapter1 As System.Data.OracleClient.OracleDataAdapter
 Dim dt As New Data.DataTable("DenseReport")
 OracleSelectCommand1 = New System.Data.OracleClient.OracleCommand
 OracleConnection1 = New System.Data.OracleClient.OracleConnection
 OracleDataAdapter1 = New System.Data.OracleClient.OracleDataAdapter
 
 OracleSelectCommand1.CommandText = "SELECT DRE_YEAR FROM DENSEREPORT
 WHERE DRE_YEAR = '2001'"
 
 OracleConnection1.ConnectionString = "user id=blah;data
 source=blah;password=blah"
 OracleSelectCommand1.Connection = OracleConnection1
 OracleDataAdapter1.SelectCommand = OracleSelectCommand1
 OracleDataAdapter1.Fill(dt)
 Label1.Text = dt.Rows.Count.ToString
 End Sub
 -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/
 
 The query above returns records. The following code does not, but it doesn't
 cause an error.
 
 -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/
 
 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
 System.EventArgs) Handles Button1.Click
 
 Dim OracleSelectCommand1 As System.Data.OracleClient.OracleCommand
 Dim OracleConnection1 As System.Data.OracleClient.OracleConnection
 Dim OracleDataAdapter1 As System.Data.OracleClient.OracleDataAdapter
 Dim dt As New Data.DataTable("DenseReport")
 
 OracleSelectCommand1 = New System.Data.OracleClient.OracleCommand
 OracleConnection1 = New System.Data.OracleClient.OracleConnection
 OracleDataAdapter1 = New System.Data.OracleClient.OracleDataAdapter
 
 OracleSelectCommand1.CommandText = "SELECT DRE_YEAR FROM DENSEREPORT
 WHERE DRE_YEAR = :pYear"
 OracleSelectCommand1.Parameters.Add(New
 System.Data.OracleClient.OracleParameter("pYear", "2001"))
 
 OracleConnection1.ConnectionString = "user id=blah;data
 source=blah;password=blah"
 OracleSelectCommand1.Connection = OracleConnection1
 OracleDataAdapter1.SelectCommand = OracleSelectCommand1
 OracleDataAdapter1.Fill(dt)
 Label1.Text = dt.Rows.Count.ToString
 End Sub
 -/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/-/
 
 Adding a : character before pYear in the OracleSelectCommand1.Parameters.Add
 call makes no difference. I still get no records.
 
 Can anyone tell me what's wrong? The database server is running Oracle 9i. I
 have installed Oracle client 8.1.5 on my development machine.
 
 Any help would be much appreciated.

 - ADO >> Enterprise Library DeriveParams with Multiple Owner Schemas SQL 2kHi
 
 I am having some issues with the above. Apologies if this is the wrong
 forum, perhaps someone will point me to the correct one.
 
 Basically the issue is this:
 
 (using SQL Server 2k sp4, EnterpriseLibrary).
 
 Create procedure dbo.TestProc @param1 int, @param2 int
 as select 'hi'
 go
 
 Create procedure bob.TestProc @param1 int
 as select 'hi'
 go
 
 When we get derive params for bob.TestProc it returns the wrong number
 of params, apparently the total number for all TestProc procedures.
 
 If anyone knows what I am talking about, I would love to have some
 feedback!

 - Net Framework >> Where to dispose whatCan you please give simple examples of objects that would be disposed in both
 of the below commented sections. E.g where should SqlConnection, SqlCommand,
 DataSet, File, Label, collection objects go?
 
 private override void Dispose(bool disposing)
 {
 if (disposing)
 {
 // Release managed resources (examples?)
 }
 
 // Release unmanaged resources (examples?)
 
 base.Dispose(disposing);
 }
 
 Thanks,

 - ADO >> how do I set a SQLdataAdapter's insert parameter to NULLIn my application I use a field of SQL type bit as a kind of tri-state
 indicater; 0, 1, and null. When I insert the record into the database using
 a stored procedure I set all the parameters and preform an executeNonQuery.
 
 My problem is that I want to be able to set this one parameter under a given
 condition to null initially but I can not find a way to add the parameter
 and have the insert work under ADO.NET
 
 here's what I'm trying (although I know it's not working):
 
 Dim spcmd As SqlClient.SqlCommand
 
 spcmd = New SqlClient.SqlCommand("spInsertUserActivity2", Me.SqlConnection2)
 
 spcmd.CommandType = CommandType.StoredProcedure
 
 Dim param As SqlClient.SqlParameter
 
 ' set up the parameter values.....
 
 If Me.ddAddAssign2.SelectedItem.Text = owner Then
 
 param = spcmd.Parameters.Add("@accepted", 1)
 
 Else
 
 param = spcmd.Parameters.Add("@accepted", Nothing) ' <<< this is where I
 wanted to set the value to DBNULL
 
 End If
 
 ' try to do the insert .....
 
 Me.SqlConnection2.Open()
 
 spcmd.ExecuteNonQuery()
 
 Me.SqlConnection2.Close()
 
 This should be an easy answer I would think. but I haven't found a reference
 as to what this constant is called.
 
 Is there one, and if so what is it called?

 - Dotnet >> How do you set the value member of a combo boxI have recently migrated to VS.Net 2005, and I am struggling to do something
 very basic with the combo box. I want to manually loop through a data table
 and add both the display text and the value manually. The reason I cannot
 bind the combo box to my data table is that there are more than one field
 that I want to combine to be the display member. So what I had to do was
 create yet another data table at run time (or an array list) and combine the
 columns in my new data table so it would display the way I want it to. This
 is much more code than simply lookping through my original data table and
 adding the item and setting the value manually. I don't want to have to do
 this for every combo box in the application. is it possible to set the value
 member of a combo box item without binding it to a data source?
 
 I also noticed that when I set the display member to a field that has a
 space in it (i.e. [last name]) the value member displays.

 - Winforms >> Windows Forms Drawing ProblemThe problem I am having is that under certain circumstances,
 text fails to draw in some controls and dialogs. The problem
 occurs primarily in the drawing of ListControls and any Dialogs
 generated via MessageBox.Show. In the ComboBox, the items are
 in the dropdown, and can be moused-over, highlighted and selected.
 When an item is selected, the text is visible in the textbox portion
 of the ComboBox control. I am not doing any sort of custom or owner
 drawing and have not interfered with the firing of events at all.
 
 The problem appears to be localized to a few machines. The text fails
 to draw on two of the =seven machines I've tested this application on.
 
 Suspecting an environment issue, I have uninstalled vstudio & .net
 and re-installed, to no avail. (I am using .Net 1.1 SP1 & VS2003)
 
 I am able to work around this, using a hack involving
 calls to Invoke on a worker thread (The full source is at the end of the
 post):
 
 /// <code>
 public Form1()
 {
 //
 // Required for Windows Form Designer support
 //
 InitializeComponent();
 
 #region HACK
 // Ensure the handle has been created so the thread can safely call Invoke.
 this.CreateHandle();
 System.Threading.Thread thread = new System.Threading.Thread( new
 System.Threading.ThreadStart( ThreadProc ) );
 thread.Start();
 #endregion
 }
 
 #region HACK
 private delegate void voidfunc();
 private void ThreadProc()
 {
 this.Invoke( new voidfunc( EmptyFunc ) );
 }
 
 private void EmptyFunc()
 {
 // Do nothing
 }
 #endregion
 /// </code>
 
 For clarity, this is how I refer to my threads:
 "control thread": The thread on which the control/form's constructor was
 called.
 "worker thread": Any thread that is not the control thread.
 
 Calling Invoke (or BeginInvoke) from the control thread has no effect
 on the drawing issue. Making the call from a worker thread is the key to
 the hack.
 
 I first suspected that the fix had to do with calling CreateHandle, but it
 doesn't.
 CreateHandle alone also does not work. It does, however, allow me to safely
 call
 Invoke from the worker thread without having to worry about timing issues.
 (In this
 sample code, I first just used Thread.Sleep(1) to pause just long enough for
 the
 handle to be created elsewhere).
 
 I am quite perplexed by this, and am at a loss to explain the effect of
 Invoke.
 
 Any help/suggestions as to a fix or explanation are appreciated.
 
 Thanks,
 Nathan Ernst

 - Visual C#.Net >> Error after calling System.Diagnostics.Process.GetCurrentProcess().StartTimeHello,
 I get some strange behaviour after calling a method on a third party
 library when I call:
 System.Diagnostics.Process.GetCurrentProcess().StartTime
 
 If I run the following code it works as expected:
 
 try
 {
 MapInfo.Engine.Session.Current.Catalog.OpenTable(@"C:
 \MapApplication\Data\ecw.tab");
 }
 catch(Exception ex)
 {
 MessageBox.Show(ex.Message);
 }
 
 But if I call:
 
 System.Diagnostics.Process
 p=System.Diagnostics.Process.GetCurrentProcess();
 string time= p.StartTime.ToShortTimeString();
 
 before the above code I get 2 errors:
 
 Form1: MXWinForm.exe - Unable To Locate Component
 
 This application has failed to start because ncsecwex.dll was not
 found. Re-installing the application may fix this problem.
 
 Why would making a call to
 System.Diagnostics.Process.GetCurrentProcess().StartTime cause
 internal errors to be thrown in my third party library?

 Matthew Lock

 - Visual C#.Net >> another question about menu bitmapsI've experimented around with the menu bitmaps but none of
 the sample code and app's I've tested with can show me how
 to add a bitmap to a context menu. I've created an app
 with no main form that resides in the system tray with
 around 15 menu items. I've been asked to put icons next
 to the menu's and i'll be dammed if i can figure out how
 this is done.
 
 The c# example code I've found on the web has been amazing
 along with xp xml theme control and xp-style balloon tool-
 tips but, adding an icon/bitmap to a context menu has
 eluded me.
 
 Anyone have any tutorials or code samples so I can see how
 its done?
 
 Thanks again.

Visual C#.Net >> Catching events from external COM server Hello,

I have a C++ COM server running that fires events (connection points) that
are then caught and processed in C#. So far, I have managed to get some
things to work, but others fail and I do not understand why.

I can pass as parameters: a single unsigned long, a single double, a single
BSTR from one application (unmanaged C++) to my C# app to get processed. I
can also send a VARIANT containing a SAFEARRAY of unsigned longs across and
extract the data. However, when I build a SAFEARRAY of doubles (VT_R8 or
VT_R4) or BSTRs the event does not get caught.

Has anyone else seen this, or have any ideas where I am going wrong? The
only discernable difference in the VARIANTS is the VT field... Unfortunately,
calling the cerver directly from C#, get the loopback to work just fine.

Any help, or ideas would be appreciated.

 - Net Framework >> .dll, other install programsI'm trying to use 3 .net C++ built dlls in a National Instruments LabWindows
 application and include them in the LabWindows (5.5) install. I've installed
 the .net 1.1 framework on the target computer, but when I run my application
 after the install, I get a "application did not initialize properly
 (0xc0000005)" error. This is occuring on a Windows XP machine, sp2. My
 application runs fine on the Windows 2000 machines I've installed it on and
 the older versions of my app that use a Visual C++ 6.0 built dll run fine on
 the XP machine. What is going on? Do I need to do something special in the
 registry or something for the .net built dlls under Windows XP? Thanks!
 
 I've also posted this under .net-general discussion since I didn't know
 really which was more appropriate...sorry about the double-posting

 - ADO >> System.TransactionI am receiving an exception while trying to use a TransactionScope. My code
 is as follows:
 
 using (TransactionScope scope = new TransactionScope()) {
 equipment.Save();
 status.Save();
 
 scope.Complete();
 }
 
 This code is pretty basic and calls some dynamic sql updates using two
 different connections to the same sql server. The sql server is located on a
 different machine than my local dev box. My local dev box is running Vista
 RTM and the SQL server is running on W2003. I can't see any issues with
 configuration on the SQL server box and am guessing that the issue is on my
 local Vista box.
 
 the exception is:
 
 TransactionmanagerCommunicationException: Network access for Distributed
 Transaction Manager (MSDTC) has been disabled. Please enable DTC for network
 access in the security configuration for MSDTC using the Component Services
 Administrative tool.
 
 Don't know if it matters or not but the sql server is part of a domain. My
 local box is not a member of the domain and I am using SQL authentication
 (successfully with the exception of the transaction issue).
 
 Any help would be appriciated.
 
 Thanks,

 - ADO >> Patterns And Practices[Copied from microsoft.public.dotnet.languages.csharp, no answer up to now
 and probably was wrong group anyways]
 
 I downloaded the patterns and practices enterprise library and found that it
 is much different for the Data library that I am used to (SqlHelper)..It's
 not just an update but a total rewrite. Anywho, figured out how to get it
 to work which wasn't too hard. What I haven't found and am having trouble
 with is updating and inserting into a database. In the SqlHelper library,
 there were methods such as ExecuteScalarTypedParams and such which allowed
 all parameters to be inside a dataset and you just passed the dataset. This
 was great because all of our data access routines returned a dataset. We
 would just modify the data and pass this same dataset/table/row back to the
 SqlHelper method and it would get updated using our stored procedures in Sql
 Server.
 
 Now, afaik, there are no methods which take a dataset for parameters. I
 have to manually created the parameters, one by one and then add them to the
 collection. Is there a better way, maybe they do exist but I haven't seen
 them? Anywho, I could always write a method in my applications that would
 take a dataset and build the parameters based on column name, column data
 type, and compare vs the stored procedures, but if it already exists, I
 don't want to reinvent the wheel.
 
 Thanks in advance,

 MVP's and experience programmer's only please!...
 
 I need to get the number of lines in a textbox so I can insert them into a
 listview. The text comes from my database and is unformatted. I display the
 text to my user in the listview. The textbox I create logically in the
 program, and I initialize the correct properties for a normal multiline
 editor.
 
 When the user changes the column size then I reload the lines accordinally.
 The problem I am having is when I get the lines property which is a
 array<^>^(). The lenght is always 1 no matter how many lines are in the
 textbox.
 
 In MFC when the lines are wraped the new line character is automattically
 inserted, but here it's not.
 
 Can you help me solve this problem? I would really appreciate it!
 
 Thanks!...

 - Dotnet >> How to merge multiple Visual Studio.NET projects into one projectDear All,
 My apologies if this is not the correct forum. Please redirect. I am a
 bit confused on where this kind of a question belongs. However I need help
 rather badly. I would like to merge two ASP.NET c# projects into one project.
 I am unable to information on going about doing it. I remember seeing a
 Microsoft support KB article many months back and can't seem to find it now.
 Any help appreciated.
 
 To give a brief of what I am trying to do:
 We are developing a customer support forum with security authorisation based
 access. We are having two KB ASP.NET applications written in c#. We would
 like to have two instances of these KB applications running as a single
 application(sharing sessions for authorisations) and with a aingle
 authentication, under another single CRM(asp.net/c#) application managing
 authentication for all three of them.
 
 I did try to do the following:
 -- Remove Gloabal.asax
 -- Web Config
 -- Take a child node in IIS as a non-application.
 
 It doesnt seem to work. Even when I try to give them unique identities by
 using different name spaces and etc, oneKB seems to load the default.aspx of
 the other leading me to believe that my integration of the three projects is
 not correct.
 
 The structure would be
 ---------
 One single
 Application
 ---------
 CRM |
 |-- KB-1|
 |-- KB-2|
 --------|
 
 Any help is appreciated. If anyone also knows the support KB link from the
 Microsoft support website, that explains this and can share , it is very much
 appreciated.
