    - Unable to hide form? in .NET 2.0Any suggestions on how to make a form not visible when displayed via
      Form1.ShowDialog() ?
      
      If I put a button on the form called "Close" and in the click event I put
      Me.visible = false, the form closes and my application terminates. I don't
      want this, I just want it to hide (Me.Hide is the same as Me.visible).
      
      I'm using a module1.vb with a sub Main() from the sub Main I Dim Form1 as
      New myForm and then call the Form1.ShowDialog.
      
      I can't find any way to hide a Form that is initially displayed (Modal) via
      ShowDialog which closing the form. Is this just not possible in .NET 2.0

    - Order of Columns in the Datagrid binding.Hi, Dear gurus,
      
      I want to bind my collection to a datagrid. The field names in my object
      show up in a weird order, and I just wonder how I could reorder those
      columns .
      
      I find some code like the following , but I don't want to do it that way
      because it won't work if I have large number of fields.
      [
      DataGridTableStyle myGridStyle = new DataGridTableStyle();
      
      myGridStyle.MappingName = "GridTableMappingName";
      
      DataGridTextBoxColumn nameColumnStyle = new DataGridTextBoxColumn();
      
      nameColumnStyle.MappingName = "GridColumnMappingName";
      
      nameColumnStyle.HeaderText= "GridColumnMappingName";
      
      myGridStyle.GridColumnStyles.Add(nameColumnStyle);
      
      myDataGrid.TableStyles.Add(myGridStyle);
      
      ]
      
      I believe there must be some better way to do that(using reflection) .
      Anybody gives me some hint on that. A link to a example is highly
      appreciated.
      
      Thanks,
      J.W.

    - Fun with products and Expression columnsI have somewhat of an interesting scenario:
      
      The form allows the user to select a service, which populates a a grid of
      product information related to that service ("service grid"). The user can
      then select from the products in the first grid and those choices populate
      the second "choices grid".
      
      The product grid is bound to a strongly-typed dataset table which can be
      filled in a couple of different ways. More on this shortly.
      
      The choices datatable contains expression columns related to a product
      table. So if the user choses Widget A, B, and C, the product prices and a
      lot of other details for that service are reflected into the choices grid
      without those values actually being duplicated into the choices table.
      
      All of the structure works well technically. But there is a fundamental
      concept decision to be made. That decision is in how to populate the
      products table. At some future date, the product catalog may grow to be
      50,000, 100,000 or even greater. My instinct is to individually populate the
      products datatable with ONLY the Widgets that relate to Service1 when it is
      selected, and then ONLY populate the widgets that releate to Service 2 when
      it is selected (each service requires a subset of the entire product
      catalog, thus limiting how big the product table may be).
      
      Where this becomes problematic is that the user may need 2 or more Services.
      So if they select products that relate to Service 1, Service 2, etc., then
      the catalog to be displayed must grow much bigger. Displaying just one set
      of products at a time will not work because this would cause a partial
      display of the expression columns in the choices grid (since the
      non-populated products still have a primary key back to the products table,
      they display a row, but not the expression data).
      
      The easiest answer would be to just populate the entire catalog in the
      products grid. Of course, the easiest solution is the most expensive in
      terms of database and processor resources. The next easiest answer would be
      to populate the product grid with just one set of products at a time. But
      this creates the above-mentioned issue with the expression columns.
      
      The technical implementation is not an issue. I'm just looking for some
      ideas or thoughts from anyone who has been down this road with multiple
      grids and expression columns.

    - Connection Pool Time OutHi all,
      
      I have the following scenario:
      App1: Asp.Net Application that shows reports from some SQL DB
      App2: Asp.Net WebService with two services exposed for clients, and a single
      â??Checkerâ?? in the Application object that checks every some time (normally 2
      or 3 minutes) for conditions in the same DB, and insert some values in it
      using a transaction.
      
      When the time spans completes, the checker retrieves via a SqlDataReader the
      ready items and make the insertions as shown:
      
      SqlDataReader reader = GetReadies();
      
      try
      {
      // do something
      
      // initialize the transaction â??transâ?? and the connection â??conâ??
      
      try
      {
      // insert using the transaction
      
      trans.Commit();
      }
      catch(Exception ex)
      {
      trans.Rollback();
      throw ex;
      }
      finally
      {
      trans.Dispose();
      con.Close();
      }
      }
      finally
      {
      reader.Close();
      }
      
      In the web application I have few pages that get information from the DB,
      and after a few retrievals, I got this error:
      â??Timeout expired. The timeout period elapsed prior to obtaining a connection
      from the pool. This may have occurred because all pooled connections were in
      use and max pool size was reached.â??
      
      So I review all code searching for unclosed datareaders or connections, for
      nothing. I use SQLHelper in the web application and I always retrieve
      datasets, anyway, I checked that all connections were closed.
      
      Then I review the code in the webservice app, I think it is correct, isnâ??t it?
      
      Even though I didnâ??t found unclosed connections, I started to watch the .Net
      CLR Data performance object with the object Current # pooled connections. The
      graph never goes over 7 connections; it oscillates between 5 and 8. I also
      started a new trace in the SQLProfile to see if it audits logout events
      occurs.
      
      And still, after a while browsing in the asp.net application, I receive the
      same error.
      
      Note: the max pool size is set to 100 explicitly.
      
      Any idea of the cause?
      
      Thank you very much.

    - Cancel windows message from reaching parentI am developing a set of controls that must function inside of an application
      that loads them through COM interop (I don't believe that makes a
      difference). The application is designed to always handled the "Enter" key.
      One of my controls is a text box which needs to allow the user multiline
      input and not being able to use the "Enter" key is borderline unacceptable.
      
      I have tried to override WndPRoc, PreProcessMessage, and a host of other
      behaviors, but I cannot get the application to stop catching the enter
      message.
      
      I have written all messages to a text file when I transition using enter
      versus using a mouse click, and I cannot even find a message that indicates
      my control received an "Enter" at all.
      
      All suggestions welcomed.

    - Resource Assigment Dates Not Matching Task Level DatesResource Assignment Dates not the same as task level dates.
      
      For Example:
      
      Task: Build Radio - 40 days dur. 1/30/06 to 3/24/06
      Resources: John 100hrs & Bill 60hrs.
      I want both John and Bill's hours spread evenly across the duration, however
      my schedule now in the task usage view shows only John (resource with most
      hrs) spread across the duration and Bill's hours are at a much shorter date.
      
      I want them both spread evenly across the entire duration. All of my tasks
      are fixed work and they need to stay that way. I can manually go into task
      usage and fixed the dates, however once status is taken Project reverts back
      to the above.
      
      Is their a setting in project I am missing?
      Is it because of fixed work?
      
      Please help!!!!

    - Anonymous type etc. in C# 3.0I understand, basically, what this C# 3.0 code does, but I am unclear
      on how it determines the data type of num and index in the lambda
      expression in the following code. Nor can I see how it gets the array
      index into the index parameter?
      
      BTW: Is there a better forum for asking these questions?
      
      public void Linq12() {
      int[] numbers = { 5, 4, 1, 3, 9, 8, 6, 7, 2, 0 };
      
      var numsInPlace = numbers.Select((num, index) => new {Num = num,
      InPlace = (num == index)});
      
      Console.WriteLine("Number: In-place?");
      foreach (var n in numsInPlace) {
      Console.WriteLine("{0}: {1}", n.Num, n.InPlace);
      }

    - Layout manager issue when docking panels?I was playing around with a new Windows form yesterday. I wanted to drop two
      panels on the form. The first would be set Dock=Top. The second would be set
      Dock=Fill.
      
      So, I dropped the first panel and set its Dock property to Top. I then dropped
      the second panel on the form and set its Dock property to Fill.
      
      Holy disappearing panels, Batman. The second panel filled the entire form
      hiding the first panel. So, when I dropped my grid control on the second panel
      which was set to Dock=Fill, it filled the entire screen.
      
      I eventually got what I needed by cutting and pasting the controls, which was a
      suggestion of a fellow developer at work, but it was a bit annoying.
      
      Is there a bug in the layout manager in the forms designer that is causing this
      behavior?

    - File format for a new application(I know it's a seond post, but I think I explain it better this way)
      --
      
      On my own I'm writting an application for the general public.
      (a bit like word, except it has nothing to do with word ;-)
      
      So far I used an embeded database engine to store the data (SQLite), I like
      the concept because this way I could load/delete/updata whatever data I need
      incrementally on demand. And I could also easily perform search.
      
      What gets me more and more concerned is that creating a new (empty) file
      (with just about 10 table, 30 index & triggers) takes up to 7 seconds!
      Very bad user experience.
      
      I'm considering my options and will gladly takes advice as I'm a bit daunted
      by the work involve just to test.
      
      - I was thinking to try an other embeded database engine, such as Firefox.
      - I was thinking to use tar-gzipped serialized file (think XML serialization
      should be better as it would be probably be better at version resistance
      (but worst perf?)), but I was wondering about the wisdom of having all my
      data in memory...
      - any other ideas?

    - Question: Load bmp and save as jpgI want to convert one bitmap file to another one.
      For example load as bmp and save as jpg.
      The loading part is simple I do this:
      
      Stream BitmapStream =
      File.Open(sSrcFile,FileMode.Open,FileAccess.Read,FileShare.None);
      Bitmap imgPhoto=new Bitmap(BitmapStream);
      iPixelsX=imgPhoto.Width;
      iPixelsY=imgPhoto.Height;
      BitmapStream.Close();
      
      The saving will be something like this; but I fail to see how I can hook up
      imgPhoto from the load to this stream.:
      
      Stream DestBitmapStream =
      File.Open(DstFile,FileMode.CreateNew,FileAccess.Write,FileShare.None);
      // how do I connect imgPhoto?
      DestBitmapStream.Close();
      
      Also I wonder if the Pixelfomat is different, lest say I load 8 bit indexed
      color palette bitmap and want to save as 24 bit RGB jpeg, could this be done
      automatic?
      Something tells me that I need to copy the bytes manually??? I hope not.
      
      Many thanks.

    - Serializable CollectionsIt seems that the only .NET Collection classes that are

      without a hashtable collection?

    - Delegates and InterfacesI have a dilemma that I'm having a tough time getting through on a VB
      2005 issue. I have a custom control for a form to display data from a
      windows form. Right now, the main form calls various web service
      methods in order to update the data. Since the data to be displayed
      depends on the call to the web service, I use a delegate that will
      invoke the method when a timer elapses. Works good for now but I want
      to create additional custom controls that will display data and have
      the main form cycle through the controls. Because of this, I figured
      that it would be easier to implement an interface on the custom
      control so that the form can instantiate the controls dynamically as
      it cycles through.
      
      So here's my dilemma. The control (or controls) could call various
      methods to get a "data refresh". Therefore, I wanted to give the
      control the delegate to invoke within itself as the main form cycles
      through each control on a separate timer. But how do I do that using
      an interface? I can't have the delegate on the interface because its
      a type. I can't pass in the signature to the c'tor because it's not a
      type. What options do I have?
      
      I appreciate any help anyone can give.

    - Custom DataGridView Columns and CellsHi,
      
      I have an application with a DataGridView that displays a Questionnaires
      questions and allows a user to fill in answers to these questions in the
      gridview.
      
      Each question knows its questionType (Date, Text, or Yes/No/Na). I have
      created a custom column that inherits from datagridviewcolumn and have
      created a custom cell that inherits from DataGridViewTextBoxCell.
      
      In my cell object, I get the OwningRow.DataBoundItem to reference the
      QuestionObject and then Get the QuestionType of the question in that row.
      
      After I do this, I use a select case statement to determine the type of
      editing control I need for Edit purposes. This way, Date questions get a
      datepicker edit control, YES/NO/NA questions get a combobox edit control and
      Text questions get a text box edit control.
      
      I have my DataGridView displaying the correct type of editing controls when
      edit mode is entered on the cell. And my Text Box and DatePicker Edit
      controls seem to be working right as well.
      
      I am having a problem with the ComboBox edit control for my custom cell.
      Even though I specify the Items list for the combobox, when the combobox is
      displayed, none of the items show up in the dropdown and even if I type an
      answer in the combobox, it doesn't enter edit mode.
      
      There are also some other strange behaviors going on in terms of values
      displayed when entering edit modes and in display mode.
      
      I would really appreciate any help here I can get. This has been a big
      problem for me to solve and have gotten close, but not yet complete.
      
      Thanks so much in advance for your help.

    - Is there any predefined delegate with no argument?Hi,
      
      I am looking for a predefined delegate which in form:
      
      delegate void NoArgument();
      
      It's quite useful than other delegate with argument, I found
      MethodInvoker in WinForms, which defined in such form, but I don't
      want to add WinForm reference all the time, since my code nothing
      relative the WinForm.
      
      The reason why I use no argument delegate is quite often is that it's
      quite easy to access local variable if I use anonymous methods, which
      may decrease the prerequest of declare a delegate with some argument
      to pass in.
      
      For example, when I try to access WinForm in thread safe way, I
      defined a static function DoThreadSafe():
      
      private static void DoThreadSafe(Control control,
      MethodInvoker function)
      {
      if (function != null)
      {
      if (control.InvokeRequired)
      {
      control.Invoke(function);
      }
      else
      {
      function();
      }
      }
      }
      
      When I use it, I do not need any parameter to pass to the "function",
      such as:
      
      value = 123;
      DoThreadSafe(progressBar1, delegate
      {
      progressBar1.Value = value;
      });
      
      It is really easy to access the variable which is accessible in
      current scope. I found many such cases which treat the delegate just a
      block of code to execute without any need of argument.
      
      I think that it's better to treat void delegate with no argument as a
      special, and predefined in dotnet framework, and may be more
      convinient to declare and call in the future version of C#. Is there
      any existing delegate in .net framework?

      public int Property {
      get { return property; }
      set { property = value; }
      }
      }
      
      My question is, Can I simply do the following:
      class A {
      public int Property;
      }
      
      Then later, if it turns out that I need to do sth when the property is set
      or get, I change it to
      class A{
      public int Property {
      get { <do sth>; return ... }
      set { <do sth>; }
      }
      }
      This way, the code that uses A should still compile. Am I right? This way
      sounds much simpler to me, you don't have to write those repetitive get&set
      unless you later find out that you need. Is this the right way of using
      properties? Am I missing sth here?
      
      thanks
