  - 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?

  - Dotnet >> saving localization in an excel workbookHi all,
    
    Does anybody know how to save localization in an excel workbook (C#
    1.1)? I'm not sure this is possible, but I'm trying to do this so that
    numberColumns keep their format no matter what local is set in the
    computer where the file is opened.

  - Microsoft Project >> Budget cash flow by monthThis should be simple...
    
    I am creating multiple summary tasks with sub's incurring estimated costs
    over the course of several months. I would like to be able to manage and
    communicate these costs by month as they fit into the company-wide cash flow
    plan.
    
    The cash flow report does little to help me summarize/subtotal the
    individual summary tasks within the whole project. Exporting the timephase to
    Excel does not let me send additional outline codes with it so I can also do
    sorting across the breadth of the project.
    
    Am I trying to do too much within a single project? Any ideas?

  - 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
    
    Private Const WM_KEYUP As Integer = &H101
    Private Const WM_MOUSEWHEEL As Integer = &H20A
    
    Protected Overrides Sub WndProc(ByRef theMessage As
    System.Windows.Forms.Message)
    If theMessage.Msg = WM_KEYUP Then
    Return
    Else

  - 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!

  - Net Framework >> Problems with Session.IsNewSession - Please HelpHi.
    
    Recently here in my work we added the following code in the Global.asax
    file to handled the session expired and redirect users to the home of
    the site explaining them the occurred (some thing like "Your session
    has expired, please restart your navigation.").
    
    public void Session_Start(Object sender, EventArgs e) {
    
    if(Session.IsNewSession && Request.Headers["Cookie"] != null &&
    Request.Headers["Cookie"].IndexOf("ASP.NET_SessionId") >= 0)
    {
    Response.Redirect("/index.aspx?timeout=1");
    // when the param "timeout" exists in the url the user
    receives the message "... Session expired ..."
    }
    
    }
    
    In our tests the code above works fine, but now sometimes we open the
    browser, type the url address of the site and the message "... session
    expired ..." appears. This occurs just in some machines and not all the
    times we access the site.
    
    Someone knows what is happening??
    
    Thanks

  - Net Framework >> Best Practices: Resources vs. SettingsCan anyone provide some direction as to what types of information
    should be put in the project's resources vs. the project's Settings.
    
    (ie. Properties.Resources and Properties.Settings)
    
    As I see, Settings can store both User and Application specific
    settings of virtually any object type. Resources is limited to
    Strings, Images, Icons, Audio, and Files and its scope is
    assembly-wide.
    
    Clearly, user options should be stored as User settings in the Settings
    files. On the other end, the Application icon should be stored in the
    Resources file.
    
    But what do you do with configuration information such as
    "DatabaseConnectionTimeout?"
    It could go as a Application scoped Setting, or it could be a assembly
    resource.
    
    I seem to be leaning to using Settings for most configuration
    information.
    
    Does anyone have an opinion?

  - 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

  - Microsoft Project >> Customizing reports in 2002 vs. 2003We use Project 2002 and have been frustrated by the apparent limitations of
    the Reports feature. Customizing reports is very canned and inflexible.
    
    Has this greatly improved in Project 2003?
    
    For example, does it let me insert any columns I want in a report? Can the
    date ranges be automated (with current date)? Can the filters in a report
    be automated for dynamic values?
    
    Or do I still have to create custom tables and only have access to specific

  - 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.

Visual C#.Net >> MdiClient Is there a way to place controls on the surface of MdiClient and have it
always stay in the background when new child forms are loaded into the MDI?
When I place controls on the surface of an MDI app and load child forms, the
controls place on the surface poke through the child form.

In the MDI paradigm, is it not wise/proper to use the MdiClient as a
controls surface?

Visual C#.Net >> MdiClient John,

The answer is NO.

When you set up a form to be a MDI container the frame work creates a
control of type MDIClinet (undocumented class meant to be used internaly
according to MSDN) that hosts all MDI children.

All other controls that you add to the form will be siblings of this control
wither over the MDIClient and all its children (MDI child forms) or under
(if it is possible to move it there) the MDIClient, thus covered and
invisible.

The only way if it was possible( but it is not) was if you could add that
control as a child of the MDIClient control, but the MDIClient control
checks all the controls added to the Controls collection to be MDI child
forms and throws exception otherwise.

  - 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

  - 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.

    }
    finally
    {
    conn.Close();
    }
    
    }
    
    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
    
    Thanks

  - 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

    What am I doing wrong?

  - 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!

  - 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....
