  - Winforms >> MDI OnMouseLeave problemHi,
    
    There seems to be a problem with mouse event handling in controls located on
    MDI child forms in .net v1.1. When the control is first made visible it
    receives the OnMouse Enter and OnMouseLeave events. If the child form is
    then hidden and re-shown only the OnMouseEnter event fires - thereafter
    neither event fires, although oddly, OnMouseMove continues to fire.
    
    The code below demonstrates the problem. Form1 is the mdi container and
    Form2 is a child form that contains a button control. The main menu item on
    Form1 is used to toggle the visibility of Form2. The button is subclassed to
    show when the events fire. When form2 is hidden and then re-displayed, the
    OnMouseEnter event fires when the button is entered, thereafter neither
    event fires until Form2 is re-loaded, but OnMouseMove continues to fire.
    
    If this is a genuine bug, I'd be grateful for any workaround tips.
    
    Thanks
    
    Jon

    Hi guys,
    
    I get an error when I send e-mails with attachments using SmtpClient.
    Following is the code snippet -
    
    MailMessage msg = new MailMessage(from, to);
    /*...all the initialization goes here */
    
    byte [] data = /* some binary data */
    using (MemoryStream ms = new MemoryStream(/*att.Contents*/))
    {
    using (StreamWriter sw = new StreamWriter(ms))
    {
    sw.Write(data);
    sw.Flush();
    ms.Position = 0;
    
    System.Net.Mail.Attachment natt = new
    System.Net.Mail.Attachment(
    ms, "test.txt");
    msg.Attachments.Add(natt);
    }
    
    }
    
    private static void sendCompletedCallback(object sender,
    AsyncCompletedEventArgs e)
    {
    if (e.Cancelled)
    {
    logmsg("E-mail send cancelled");
    }
    else if (e.Error != null)
    {
    System.Diagnostics.Debug.WriteLine(e.Error.ToString());
    logmsg(e.Error.Message + ' ' +
    e.Error.InnerException.Message);
    }
    else
    {
    logmsg(success)
    }
    
    }
    
    The error I am getting in the above method is -
    
    System.Net.Mail.SmtpException: Failure sending mail. --->
    System.NotSupportedException: Stream does not support reading.
    at System.Net.Mime.MimeBasePart.EndSend(IAsyncResult asyncResult)
    at System.Net.Mail.Message.EndSend(IAsyncResult asyncResult)
    at System.Net.Mail.SmtpClient.SendMessageCallback(IAsyncResult
    result)
    --- End of inner exception stack trace ---
    
    What am I doing wrong? The code seems to work fine if no attachment
    is
    supplied.
    
    cheers

  - Winforms >> Get reference to datagridview column from given coordinates.Does anyone know a method to retrieve a reference to the datagridview
    column that contains given client coordinates?
    
    Essentially I am trying to implement drag and drop functionality from a
    
    listbox to a datagridview. In this case I am using an item dragged from
    
    the listbox into the datagridview to rename the datagridview column
    where that item is dropped.
    I know how to implement the drag and drop functioanlity using events. I
    
    just dont know how to get a reference to the actual column where the
    item is dropped. So far I have gotten as far as being able to retrieve
    the client coordinates in the datagridview of the actual drop point.
    Anyone know how I can use those to get a reference to the column?
    
    Thanks in advance for any help.

  - Visual C#.Net >> How to hide a property on DataGridIs there an attribute for a property on an object that saus :"This property
    is not shown on a DataGrid" ?
    
    I know it can be done on the grid itself, using DataGridTableStyle,
    DataGridColumnStyle etc. But I`d like to get the same result by changing my
    class, not at run-time changing grid`s behaveiour.
    
    A small example:
    
    public class User
    {
    private string m_Uid;
    private string m_Name;
    private string m_Pwd;
    
    // UID should be visible on a DataGrid
    public string UID
    {
    get {return m_Uid;}
    set {m_Uid = value;}
    }
    
    // Name should be visible on a DataGrid
    public string Name
    {
    get {return m_Name;}
    set {m_Uid = Name;}
    }
    // PWD should *NOT* be visible on a DataGrid
    //is there an attribute for this ?
    
    [SomeAttribute.PreventBindingToGrid(true)] // this is what I`m looking
    for
    public string PWD
    {
    get {return m_Pwd;}
    set {m_Pwd = value;}
    }
    } // End of User.
    
    On a form with a DataGrid - gridUsers, We implement (implementation not
    shown) a method to fetch users into an ArrayList of User objects, and bind
    gridUsers to the list:
    
    ArrayList alUsers = FetchUsers();
    gridUsers.DataSource = alUsers; // Currently, the grid has 3 columns,
    including PWD.
    Can this be done (prevent PWD property from binding) ?

    Your Web Developer 2005 express added that crappy and unneeded attribute to

    subqueries (I'm using the Microsoft OLE DB Provider for Oracle and have an
    Oracle 8 database). The query works just fine, though, and returns correct

    Here's the query ...

    error ...
    
    "There were errors configuring the data adapter."

  - Dotnet >> VB.Net and DynamicsHello
    
    Does anybody know if there is a way to dynamically have a dataset linked to a predefined crystal report? The project initially was created to deal with a few static reports but now my client has the need for much more reporting and it would be much easier to do this dynamically, if at all possible
    
    Current situation
    User is coming from a form where parameters for a report are specified. These are then passed to the form that will generate the Crystal Report. From this point, a dataset would be created and based on the information, the query that was sent to the database would be displayed in the CrystalReportViewer.
    
    I have yet to figure out a way around this because the crystal report cannot be created without a predefined dataset, and this would seem to suggest that the dataadapter would also have to be predefined. :(
    
    Is there a better way of doing this??
    
    Cheers

ADO >> DataSet Binding Question Nevermind I figured it out. In the code 'this.modelComboBox.DisplayMember =
"tblModels.strCode"' it was wrong I did not need to specify the tbl name.

  - Visual C#.Net >> Deployment projectsWe want to deploy a large CSharp/SQL Server system.
    
    We are successfully using the 'setup project' (under setup and
    deployment projects) to build our deployed system.
    
    With our stored procedures, we would ideally like the facility to be
    able to automatically add all our stored procedures in SourceSafe/disk
    to the deployment project without having one of us having to select
    them manually and adding them. That way, we could build our deployment
    projects automatically even if we have a number of new stored
    procedures in each deployment.
    
    Basically, we want our deployment to contain assemblies (known) and a
    variable number of stored procedures.
    
    One way is to write a program that creates a deployment solution file
    based on the stored procedures + all the necessary other files, but we
    would prefer not to do this if there is a better way.
    
    Does anyone have any bright ideas?

    Error 1 '<blah>DataTable' does not contain a definition for 'HasChanges'
    
    Am I doing something stupid or do datatables not have this method available?
    
    Thanks,

  - Visual C#.Net >> Live Meter Data on the Web - Advice PleaseI've been asked to display some meter data on the web and I need preliminary
    advice.
    
    We have several hundred meters on site, with a system that writes out xml
    files at 10 second intervals containing their data. (These files are
    overwritten every 10 seconds, not appended to.)
    
    First, I need to display two numeric pieces of this data just as numbers in
    a web page. Naturally that's easy enough: where I'm stumped is REFRESHING
    that data when it's updated every 10 seconds. Of course I don't want to
    refresh the whole page, but only update a particular number when its
    associated xml file is updated.
    
    I've seen this done client side with javascript, but it was pretty cludgey.
    Can ASP.NET help me here with a kind of persistant connection to these xml
    files? (I thought the DataSet did such business out of the box, but it
    doesn't as far as I can tell.)
    
    Second, I need to use this data later for graphic trend displays. In other
    words, I need to show in graph or chart form how each of these meters is
    performing over time. Since the xml files are overwritten, I obviously have
    to persist each piece of data somehow. I can think of any number of ways to
    do this, but none of them seem too elegant. Any advice anyone might have
    will help me think this through.

  - Visual C#.Net >> XML writing errorHi all,
    I have developped an application that generate XML documents.
    At most time it works fine, but sometimes (when the size of data to export
    is big) i got the error message :
    << The StartElement token in the Epilog state will generate a nonvalid XML
    document :
    at System.XML.XMLTextWriter.AutoComplete(Token token)

    localName,String ns) at.....etc.>>
    I have reviewed well formedness of my XML instructions but i have found no
    error in them.
    Please, give me any idea to track and solve the problem.
    Thanks in advance.

  - Winforms >> ContextMenuStrip on header of TabPage???Hi all,
    
    On a Windows Form I have a TabControl and a ContextMenuStrip. Now I'm
    trying to get the ContextMenuStrip only to be shown when right clicked
    on the HEADER of the current TabPage (the TAB as I call it). Any ideas
    (detecting the right clicking is not the problem of course, but my
    context menu shows up on every location of the TabPage, not just the
    header)? I once did this in Java (long time ago) so it must be
    possible with .NET ;-)
    
    Thanks for your help,
