  - ADO >> Oledb Connection from ASP.Net on Windows 2003 does not workThe following code does not work from an ASP.Net application on Windows
    2003 IIS 6 (application isolation mode).
    Basically I am trying to connect to a Sharepoint catalog through the
    oledb provider for Internet publishing (WebDAV)
    
    It works fine from a windows application on Windows 2003. It works in
    ASP.net web application on Windows2000

    I have also tried the following and none of these works on 2003/IIS6
    
    Changed the website to run in IIS 5 isolation mode
    added NT AUTHORITY\NETWORK SERVICE to the administrator group
    tried opening the connection in the asp.net in a secondary thread
    Impersonated the asp.net web application to run as a user with
    administrator privileges
    Turned anonymous authentication off and ran the website with integrated
    authentication so it takes the logon user credentials
    
    Any help to point me in the right direction would be greatly
    appreciated

  - Dotnet >> LNK2001 with mixed managed/native dll'sHello,
    
    I'm running into a linking problem when trying to build a dll like so...
    
    step1:
    native C++ library & managed c++ = managed c++ dll (this one builds fine)
    step 2:
    managed c++ dll (the one that built ok) & managed c++ = managed c++ dll
    
    step 2 results in this link error...
    error LNK2001: unresolved external symbol "public: bool __thiscall
    rw::audio::core::System::IsLocked(void)const "
    (?IsLocked@System@core@audio@rw@@$$FQBE_NXZ) SpliceUnity.obj
    
    ...among others. The one thing I noticed that is similar between all of
    these link errors is that the routines they are refering to are const
    methods.. for example...
    
    bool IsLocked() const;
    
    Any methods that are not const link fine. By the way, these routines are in
    the native c++ library.
    
    Another strange bit of info, if I use the routine IsLocked in both managed
    c++ libraries, the one in step 1 still builds fine, and the link errors show
    up when linking step 2. If I comment out all of the references to IsLocked
    in the step 2 dll, I still get the link error until I comment out the call to
    IsLocked in the step 1 dll. Once they are removed from BOTH managed
    libraries, the link error disappears.
    
    I've scowered the web but can't find a resolution to this. I'm wondering if
    the const at the end of these methods, or the calls to those routines from
    within my managed dll's are causing the two to be mangled differently (maybe
    using __clrcall instead of __thiscall).
    
    Any help is greatly appreciated.
    Thanks

  - ADO >> ERROR: Invalid Object NameHi,
    
    I'm currently trying to retrieve information from a specific table within a
    SQL Database using the following code:
    
    Dim oSqlCommand As New SqlClient.SqlCommand
    oSqlCommand.CommandType = CommandType.Text
    oSqlCommand.Connection = mSqlConnection
    oSqlcCommand.CommandText = "SELECT * FROM SOMETABLE"
    
    Dim oSqlReader As SqlClient.SqlDataReader
    oSqlReader = oSqlCommand.ExecuteReader
    oSqlCommand.Dispose()
    
    Connection to the SQL Database is performed like this :
    
    strConnection = "Driver={SQL Server}" & _
    ";Server=" & mServerName & _
    ";Database=" & mDatabaseName & _
    ";Uid=" & mUserID & _
    ";Pwd=" & mPassword & ";"
    
    mSqlConnection = New SqlClient.SqlConnection(strConnection)
    mSqlConnection.CreateCommand()
    
    While performing the query with the SOMETABLE owner mUserID, there is no
    problem accessing the SOMETABLE information.
    
    Therefore, while performing the query with the Database System Administrator
    and DB owner mUserID, I'm unable to access the SOMETABLE information getting
    the Invalid Object Name 'SOMETABLE' error message.
    
    If I tried to perform the same thing using EXCEL query, the SOMETABLE
    information could be accessed by both mUserID which is not the case with my
    application.
    
    It seems that only the SOMETABLE owner could access the table. Why the
    Database System Administrator and DB owner could not access the SOMETABLE? Am
    I doing something wrong while connecting to the Database? Do I have to change
    permissions? Why is it working with EXCEL and not with my application?
    
    Thanks

  - Net Framework >> WM_KeyUp message on ComboBoxesThe WM_KeyUp message doesn't seem to be firing for a combobox when the
    DropDownType is set to DropDown. Can anyone shed light as to why, and how to
    get around it? I'm trying to fix the NoKeyUpCombo inherited combobox (code
    below) to work with true ComboBoxes (where you can type into the box OR
    select from the list), but every DataGridComboBoxColumn example out there
    seems to only support the DropDownType of DropDownList.
    
    Here's the control for those that haven't seen it (the reason for cancelling
    the KeyUp is to prevent double-tabbing - the tab KeyDown and KeyUp events
    both cause a cell change for some reason):
    
    Public Class NoKeyUpCombo
    Inherits System.Windows.Forms.ComboBox

  - Winforms >> Auto Expanding TextBox/ControlsHi there,
    
    I've googled this problem, and not found a suitable solution yet. I was
    wondering if anyone has made any progress?
    
    Basically, I want to make a textbox automagically adjust it's height to show
    all the text it contains. So, if I add text then it grows, and it shrinks if
    I remove text. This is similar to the CanGrow property in MS Access
    controls.
    
    I'm willing to purchase a control if anyone knows of any, I'd just like to
    get this cracked without spending *too* much time "fiddling" about!
    
    Any help much appreciated

  - ADO >> Connection pool count too high?I am trying to determine if the # of connection pools our app is using is
    'normal'/acceptable, or if there is a problem.
    
    Our web application is all asp.net, using ADO.NET and SQL Server 2000 STD.
    The app is run on a Windows 2003 Server Web Edition and IIS 6. The
    application is broken up into 2 webs in IIS. One that contains only one
    Application Virtual Directory, and the other that is broken up into 7
    Application Virtual Directories.
    
    Every Sql Command uses the same connection string. All data access opens and
    closes its own connection immediately before and after the command is run.
    
    We normally have about 45 - 60 concurrent users of the app at any given
    time. And every page runs several sql commands every time they load.
    
    Below are the performance counters from both the web and sql servers that I
    thought were important for this research.
    
    142 connection pools and 429 pooled connections seems very high to me. I
    know that it is hard to determine what should be 'normal' without knowing
    more about the app, but at a very high level, does this seem normal or would
    this indicate there is a problem?

  - Visual C#.Net >> can't use an array property of a user control in designer?Hi,
    
    I have a user control and I want an array of items to be available to
    the user
    
    In my case these items are a class called Needle.
    I added a property called Needles to get\set the array (Needle[]) and
    it seems to work except that the designer doesn't handle it correctly
    
    In the property page of the designer I see the property and I can
    click on it and I get a property window and I can add new Needles.
    These are thrown away, they never make it to the cs file and I don't
    know why.
    The will remain in the design property page until I close VS or
    compile.
    
    I have put the code in the Form_Load() to set the array and it works
    but the property page does nothing
    
    The code is below, {1} is where I would expect the designer to have
    inserted code (similar to {2}) to create the objects.
    
    Anyone have any idea what is wrong?

  - Microsoft Project >> Predecessors are not updatingHi!
    
    I'm using project to schedule out a production chart for 64 units of the
    same vehicle.
    
    I have a task "Final Paint" which I have needed to move from prior to Item
    46"Inspection" to after Item 46"Inspection". I can move the task with no
    trouble, but when I try to update its predecessor to be Inspection (which is
    now Item 45), The start date for Final Paint doesn't change.
    I have tried entering other tasks as the predecessor to try and get this
    line to change "eg predecessor 16FS" and still the this item will not follow
    on.
    
    Is this a known problem with project 2003, or am I doing something wrong?
    Usually I can manually enter "line no"FS without any trouble.
    
    Please help, thanks in advance....

  - ADO >> DataSet / DataTable SQL UpdatesHi Everyone,
    
    I need to know if this is right after about an hour of reasearch
    concerning set-based operations against an ADO.NET DataSet or
    DataTable.
    
    It looks like MS discourages the use of anything (legacy) concerning
    the use of a "current record".. ie, MoveFirst(), MovePrevious(), etc.
    in favor of set based operations on a DataSet or DataTable.
    
    From what I've read, we can "SELECT" records from one of the above
    objects, but there's no mechanism to "UPDATE" or "DELETE" rows other
    than iterating through an array returned by the .Select() method. Is
    this right? I understand that a DataSet/DataTable represents a fully
    disconnected source of data and why set-based commands would be a
    logical step forward, but why only include "SELECT"?
    
    Thanks in advance for any advice at all!
    BILL

  - ADO >> Macro to Generate OleDbCommand for a Stored Procedure callAfter searching for just such a macro/tool, I decided to write one
    myself. After writing one myself, I decided to post it for others who
    might be searching as I was:
    
    Here's the macro. Since clipboard access is not available in Visual
    Studio Macros, it's based off the current selection. What I do is
    select my stored procedure code in Visual Studio and run this macro.
    The output is put into the Output window pane, and I copy and paste it
    from there. It's already saved me hours and I only wrote it
    yesterday.
    Sky's the limit on customizing this thing. Just please let the world
    know if you make some sort of massive improvement. It's just a Macro,
    so make all the changes you want to suite your coding style, etc.
    
    By default, if uses a connection object named "conn" and it calls
    "ExecuteNonQuery". Also, as you can see, it converts the T-SQL types
    that I had immediate need for to OleDbDataTypes. Add as needed. Go
    to town!

  - Visual C#.Net >> OO AnalysisAlright, I've read Jesse Liberty's book almost cover to cover. So now I
    know something about using C#. I have an idea for a program I want to
    write.
    
    I have NO IDEA what objects I need, or how to set things up. Are there
    any good object-oriented books or website tutorials on ANALYSIS that you
    would recommend? I need something that will teach me to diagram and
    organize my thoughts.
    
    The program I want to write transfers certain files and directories from
    one PC to another. It seems I need a source computer object and a
    destination computer object. Beyond that, to what level should I
    extrapolate objects? Should I have a log object, for instance? Surely,
    I wouldn't have an object for each program I want to copy (I was
    thinking of doing an enumeration for software). I need to know where to
    draw the lines.

  - Visual C#.Net >> custom logging sink for logging application blockI have written a custom logging sink for the enterprise library logging
    application block (June 2005). I have been able to configure it as expected
    from the UI config tool (EntLibConfig.exe).
    
    I have built a console application to test it with and I am getting the
    following error message write to the default trace log when I attempt to use
    my custom logging sink.
    
    'An error occurred while the Distributor was processing the message. Please
    check your configuration files for errors or typos. Verify that your sinks
    are reachable (queues exist, permissions are set, database exists, etc...)'
    
    This might be security related can anyone give me the answer on how to fix
    this?
    
    I can see from VS that the module for my custom logging sink is loaded at
    runtime but I am unable to break into the assembly which indicates to me
    that any of the 'LogSink' overridden methods are not being called.

  - Visual C#.Net >> OOD QuestionThis is a design / inheritance qus.
    I have class Task.
    This is a base class for some specific tasks
    
    Say
    WorkOrderTask : Task
    TimeSheetTask : Task
    
    Now Task has a function GetDetails() which gets all info about task. This
    makes a database call.
    
    I override this in the derived class. For implementing this in derived
    class i see following 2 approaches.
    
    Approach 1. WorkOrderTask .GetDetails()
    {
    Calls base.GetDetails(); to get base details, populates in the
    object
    Gets details specific to WorkOrderTask, populates in the object
    returns;
    }
    
    Approach 2. WorkOrderTask .GetDetails()
    {
    Get details specific to WorkOrderTask as well as the base class
    details, populates in the object
    returns;
    }
    
    The problem with
    
    Approach 1
    I have to make 2 database calls.
    
    Approach 2
    If theres some change in base class I need to take care of these in all the
    derived classes as well.
    Whereas, Approach 1 is advantageous here as by modifying only the
    Task.GetDetails funciton ( this is the base class ) function i have all the
    values and i do not need to touch the derived classes.
    
    Was thinking this might be a very common problem, so perhaps many of might
    be able to guide me on the approach i must take here. Perhaps anything other
    then the two i have talked about.

  - Winforms >> Tab key in a datagrid on a modeless dialogHello
    
    I have a datagrid on a modeless dialog and when the focus is on the datagrid
    the tab key doesnt work. Now, I understand that when you have a modeless
    dialog then there is some kind of message loop missing and that is why the
    tab key doesnt get captured. That is why I though I could inherit my own
    datagrid and override the ProcessKeyPreview to capture the Tab key. This
    only works with the Enter key though. The Tab key never gets sent to the
    DataGrid. Does anyone know where the tab goes? Do I have to use the textbox
    column in some way to get hold of this one. I also wonder why the Enter key
    is seen by the datagrid but not the Tab key.
    
    Thanks for any input

  - ADO >> Batch Update ProblemHi,
    I am porting an ADO.NET 1.1 project to version 2.0 and trying to take
    advantage of the dataAdapter's UpdateBatchSize property. When I set this to
    0 and change my updatedRowSource to either NONE or OUTPUT PARAMS, I get the
    following error when trying to update more than one row.
    
    5/10/2006 12:52:18 - Exception occurred ---> Description:
    ExceptionHandling.CustomException: The ConnectionString property has not been
    initialized. ---> System.InvalidOperationException: The ConnectionString
    property has not been initialized.

    dataTable, DataTableMapping tableMapping)
    at System.Data.Common.DbDataAdapter.Update(DataTable dataTable)
    
    My update method is as follows. I initialize the data adapter's update
    related sql command objects' connections at run-time. (I am not using
    'USING' as I want to catch exceptions)
    
    Private Sub DoUpdate()
    
    Dim cn As New SqlConnection(strConn)
    
    Me.dataAdapter1UpdateCommand.Connection = cn
    Me.dataAdapter1DeleteCommand.Connection = cn
    Me.dataAdapter1InsertCommand.Connection = cn
    
    Try
    
    Me.dataAdapter1.Update(Me.Ds.dtMyTable)
    
    Catch ex As Exception
    LogExceptions(Me.Name, "DoUpdate", ex)
    MessageBox.Show(strChgError, strSrvrError, MessageBoxButtons.OK,
    MessageBoxIcon.Error)
    
    Finally
    cn.Dispose()
    
    End Try
    
    End Sub
    
    Can anyone tell me why this happens and how to fix it. I can correct the
    problem by setting the updateBatchSize to 1, and the problem does not occur
    when only one row is being updated. I am connecting to SQL Server 2000 SP4.
    
    Thanks.

  - Winforms >> A Newbie QuestionHi All,
    
    I'm trying to develop a prototype for a small Room Booking application. This
    is a 3 tier application. The presentation layer consists of Windows Forms.
    There will be multiple concurrent clients. The application needs transaction
    supportivity.I thought of developing in .NET C#. The data base is going to
    be SQL Server 2000.
    
    I thought of following the design guidelines mentioned in the
    MSDN,Application Architecture for .NET Designing Applications and Services
    from Microsoft
    (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnbda/html
    /distapp.asp).
    
    I have some questions. For my distributed application which technology would
    be best suitable?. Enterprise Services COM+ components or .NET remoting or
    Web Services? How can I take the decision? My application needs quick
    response (Speed is important).
    
    Thanks in advance.

  - Visual C#.Net >> Create a string of n pixel width...Since I have no control over a treeview's scroll bars (i'm drawing icons
    and text to the right of the treenodes) I've decided to just add some
    special text to the end of my tree node text which I will then strip out
    when it comes to drawing the treenode into the treeview...
    
    Anyway I know there is a way to get the pixel length of a string that
    already exists, but is there a good way to create a string of characters
    that are a certain length? Should I just have a function that loops
    adding 'x' until it's a certain length? Since this will only be run
    when a node is created or when a node's special properties change I'm
    just planning on doing this - unless any of you know of a better solution.

  - Dotnet >> Strange, intermittent "Configuration Error" involving a COM DLLI have a Dot Net project that references a COM DLL called
    "Crypto.dll," which is registered on my machine. I added the reference
    via the "Add Reference" dialog in Visual Studio Dot Net, and I am
    successfully accessing methods in this DLL in some of my classes.
    
    "Interop.CRYPTOLib" is the name of the interop VS.NET created for me
    when I added the reference.
    
    Frequently, when I try to run my application, I get the error that
    follows.
    
    What's very frustrating and puzzling is that sometimes this error
    occurs and sometimes it doesn't; it will occur 10 times in a row, then
    I'll walk away from my desk for 15 minutes, and the application will
    run fine.
    
    Rebootimg my machine always seems to fix the error, but only for a
    short period of time; it always recurs eventually.
    
    Any help that anyone could give me on this would be greatly
    appreciated...I'm really stumped! Thanks in advance!!
