    - Need suggestion: importing data into SQL ExpressI have an ASP.NET 2.0 website with a SQL Express database. I also have an
      excel spreadsheet with alot of data on it. (If need be I can save it as a
      CSV, XML, or whatever...)
      
      I want the user to be able to import the data into an SQL Express database
      (existing table) via a button on my ASPX page.
      
      Do you recommend importing the data as XML into like a dataset, then
      updating the SQL Express table with this dataset? If so, what's the easiest
      way to update a table with an existing dataset? Additional
      recommendations/suggestions appreciated...
      
      Thanks!

    - UrlAllowList does not work when opening helpfile from .NET appBackground:
      
      Since Microsoftâ??s security update 896358, security update 840315 or Windows
      Server 2003 Service Pack 1, you can not longer open and see topic content in
      help files on the network. This is true even for files in shared folders on
      local intranet and even if the user has enough previliges to open the help
      file it self. This is because help files indirectly could open active content
      that is placed in some other unsecure location.
      
      However, there is two known workarounds for this problem. One is to set the
      MaxAllowedZone under the HTMLHelp\ItssRestrictions key in local registry.
      
      Problem:
      
      When launching a HTMLHelp file through .NET code and the Help.ShowHelp
      method and setting the MaxAllowZone = 1, all works fine. But when using
      UrlAllowList this does not work. But when opening helpfile directly from
      Windows UrlAllowList all works fine.
      
      Why doesn't UrlAllowList work from .NET app?

    - Debugging assemblies: Forcing EXE to reload DLLWhen debugging an assembly, obviously a startup Exe file must be set.
      I've run into a snag once in a while that appears to be caused by VS
      referring to the Exe's *local* copy of the target DLL rather than the
      one that has just been recompiled.
      
      Is there an recommended method for ensuring that a newly compiled DLL
      also gets copied over the DLL in the startup Exe's folder?

    - Save lines drawn in the picturebox as an lmageHave used DrawLine() method to draw some lines in the picturebox (sort
      of a barcode) in the picturebox paint event.
      This diagram has to be saved as an image in bmp or tiff format.
      But the problem is that these lines are not recognized as the image o
      
      the picturebox.
      It shows picturebox.image = nothing.
      
      How do we convert these lines drawn as the image of the picturebox so
      that it can be saved.
      
      Thanks for any help

    - Assign ado.net dataset to combobox?I have an app that I have been using this code to fill a datagrid:
      
      DataSet ds = new DataSet("Recordset");
      OleDbDataAdapter da = new OleDbDataAdapter();
      
      // Call data adapter's Fill method to fill data from ADO
      // Recordset to ADO.NET dataset
      da.Fill(ds, rs, "tblTravelEventType");
      
      // Assign data set to grid control
      DropDownList1.DataSource = ds;
      DropDownList1.DataMember = "tblTravelEventType";
      
      But now I want to assign just one of the fields to the combobox1..
      How can I do that? Can you give me an example?

    - Importing from a text file to a DatasetI have a large(1.25M), fixed field delimited, text file which I want to read into a DataSet. So, I opened a StreamReader, read a line, assigned the values to a new DataRow, and finally added the DataRow to a DataTable in the DataSet. Seemed to be a staight forward task but boy did it progress at a snail's pace!
      
      So I tried to speed things up by first importing the data from the text file into SQL Server. To my amazement, the text import went like lightning! How can I get lightning fast text import?

    - Connection StringsHi
      
      Trying to sort out how to implement the use of connection strings with our new .Net Data Acces Layer(DAL).
      
      2 solutions have been propoesed. Both suggest storing the connecion string in the machine.config file. The DAL uses SQLCleint namespace. At this stage there is only one SQL data store(with multiple data bases), but that might change in the future. Also, we are not using COM+ / Enterprise services, only manual transactions.
      
      The 2 solutions differ, in that the first requires each part of the application to get the connection string, and pass it through every tier/layer (presentation, business, dalcs) to the DAL ...
      
      The second solution makes it possible for the DAL to retrieve a named datasrouce from machine.config, and only DAL Components(DALCS which inherit the DAL) can specify a datasource.
      
      If this makes any sense, can anyone suggest best of the two options, and why they think that? And if anyone has an even better solution to post that up would be great !
      
      Cheers

    - Update Task ProgressI am a beginner in using Microsoft project and project server (2007).
      
      My questions are as below:
      1. I did create 2 user in PWA(Project Manager(PM) and Team member (Mr. A)).
      PM publish a project schedule to PWA which all tasks in the project asssigned
      to Mr. A. How Mr. A check his task and update the % of work complete?
      -I tried login as Mr. A and I only found those tasks can add into "My Time
      Sheet" but not in "My Task". The button in "My Task" to import time sheet was
      disabled.
      2. How PM track the project status?
      -I tried use local MS Project 2007 connect to server then goto Collaborate>
      Request Progress Information but seem no different from the baseline plan
      compare with the actual progress.

    - HARD QUESTIONMy company and I wish to create an archive for storing all data from
      previous projects. However, when I create a Consolidated Project it only
      utilizes a shortcut to the projects. I'm wondering if there is any way to
      load Project A into Project B such that Project A can then be deleted
      (without deleting it from Project B). The way consolidating projects is set
      up makes this impossible. If there is a way to load all information from
      one project to another please let me know!! Even if it's long and
      involved!! (I can make a macro) Thank you for your time and energy reading
      this. please if you can help post a reply here or e-mail me at

Jack -

Are you sure that "multiple windows services" is the best
design? How about a single handler that creates worker
threads as watcher events are fired...

    - Undo/Redo PatternHello,
      
      I've tried to find information about how to implement an Undo/Redo pattern.
      This article describes such a pattern:
      http://www.codeproject.com/csharp/PcObjectUndo.asp , but is a little bit to
      narrow, since it only can handle 1 object, and since it only works on
      properties.
      
      What if you , in an application, have more than 1 object , and you want to
      use undo/redo on them?
      What if you'd like it to work on methods as well as properties?
      
      If there is a better pattern than the one in the link, that will let me do
      this, please let me know.

    - Scheduling from fixed finish dates?What is the best way to schedule a series of activities from a fixed
      finish date? We are planning an event that takes place on July 23, 2005. I
      am trying to plug in things like:
      
      Issue press release 3 days before event (must occur on)
      
      Issue press release 30 days before event (could be +/- 3 days)
      
      Design, print, mail brochures must be finished 60 days before event.*
      
      * Design and print can happen early but mailing must
      take place no earlier than 60 days before event and no
      later than 45 days before event.
      
      These activities needs to be relative days in case we have to reschedule
      the entire event for a later date. However, most tasks MUST happen as
      outlined above (finish x number of days before event).
      
      I am fairly used to constructing projects that have regular SF relations
      and the end date floats depending on the length of time. Here we're trying
      to plan backwards and I'm not sure I'm doing what I want.
      
      Thanks for the help!

    - Getting Caret Position from another processDoes anyone know how I can get the caret position in terms of screen position
      from the currently active window? By currently active window I don't mean
      just mine, rather any window.
      
      Basically the end result I want is to position a floating tooltip style
      window next to wherever the user is typing (their caret) regardless of what
      app they are using.
      
      I've tried calling GetCaretPos, however this only seems to work when my app
      currently has the focus. At all other times the POINT returned by
      GetCaretPos is 0,0. I think this is due to other windows destroying their
      Carets when they lose the focus.

    - Excel/PowerPoint Quit eventI'm working with Office Application objects in a client/server
      WinForm application which allows the user to access remotely
      stored files. When the user opens the remote file, it is
      downloaded to their machine, and it is opened in the appropriate
      Office app.
      
      I've hooked the various BeforeSave events to let me know if/when
      they've made modifications to the file, so I can mark it as dirty.
      However, I would like to know when the Office application has
      terminated, so that I can then upload dirty files back to the
      remote server. Word.Application has a Quit event in its parent
      interface ApplicationEvents4_Event, so I can hook that. However,
      I haven't seen a similar Quit event in the Excel and PowerPoint
      objects. Anybody know where it is, or if it exists?
      
      (I'd also like to know when the Office applications quit so that
      I can remove the COM references and null out the variables that
      point to them.)
      
      Oh, and I can't use the BeforeClose/Close events, because if
      the user hits the Close Window button on the frame of the
      application, then the document is closed it is saved. (Oddly enough.)
      
      Thanks,

    - Good books about .NET and C#?Hello!
      
      I am a software developer with 5+ years of C++ experience and VB
      experience since version 1.0 until 6.0. I would like to learn more
      about C# and .NET framework. I have some VB.NET, C++/CLI and C#
      experience. So far the books I have come accross start with basics
      like "writing loops" and "how to use IDE" and stuff like that. I
      don't care about books like that. Is there any books that don't
      assume the reader is complete beginner? Something that would go in
      depth about the language? And something about common idioms and
      programming styles of C#? Is there a FAQ of this newsgroup? Any
      suggestions?
      
      Thanks,

    - Bug with DataColumn.AutoIncrementSeedHi! I think I found a bug with DataColumn.AutoIncrementSeed. I tried to
      communicate it via the Microsoft Feedback center, but after about half an
      hour of trying to get through the feedback process without webforms breaking
      down, I gave up.
      
      The bug is: Under certain circumstances, the number to be automatically
      incremented has a false value.
      
      This is how to reproduce the bug (complete code below):
      1) Call TestCode1(): an XML file TEST.xml is created in C:\
      2) Call TestCode2() with a breakpoint in line
      
      dr["Text"] = "Text2";
      (= third to last line)
      
      3) The new line created should have an ID of 1 (ID of existing line, which
      is 0, plus 1); but it has an ID of 0.
      
      With an AutoIncrementSeed of 1 (instead of 0), the problem disappears (the
      two IDs are correctly numbered 1 and 2).
      
      --Complete code:
      
      private void TestCode1()
      {
      System.Data.DataSet ds = new DataSet("TestDS");
      System.Data.DataTable dt = new DataTable("Test");
      ds.Tables.Add(dt);
      System.Data.DataColumn dc1 = new DataColumn("ID", typeof(int));
      dt.Columns.Add(dc1);
      dt.Columns[0].AutoIncrement = true;
      dt.Columns[0].AutoIncrementSeed = 1;
      dt.Columns[0].AutoIncrementStep = 1;
      System.Data.DataColumn dc2 = new DataColumn("Text",
      typeof(string));
      dt.Columns.Add(dc2);
      System.Xml.XmlDataDocument xmlTest = new XmlDataDocument(ds);
      
      System.Data.DataRow dr = dt.NewRow();
      dr["Text"] = "Text1";
      dt.Rows.Add(dr);
      dt.AcceptChanges();
      
      xmlTest.Save("C:\Test.xml");
      
      dr = dt.NewRow();
      dr["Text"] = "Text2";
      dt.Rows.Add(dr);
      dt.AcceptChanges();
      }
      
      private void TestCode2()
      {
      System.Data.DataSet ds = new DataSet("TestDS");
      System.Data.DataTable dt = new DataTable("Test");
      ds.Tables.Add(dt);
      System.Data.DataColumn dc1 = new DataColumn("ID", typeof(int));
      dt.Columns.Add(dc1);
      dt.Columns[0].AutoIncrement = true;
      dt.Columns[0].AutoIncrementSeed = 1;
      dt.Columns[0].AutoIncrementStep = 1;
      System.Data.DataColumn dc2 = new DataColumn("Text",
      typeof(string));
      dt.Columns.Add(dc2);
      System.Xml.XmlDataDocument xmlTest = new XmlDataDocument(ds);
      
      xmlTest.Load("C:\Test.xml");
      ds.AcceptChanges();
      
      System.Data.DataRow dr = dt.NewRow();
      dr["Text"] = "Text2";
      dt.Rows.Add(dr);
      dt.AcceptChanges();
      }

    - "Error executing program!" when starting .Net 2.0 applicationHi there,
      
      i've a problem with the .Net 2.0 Framework. I've created a very simple
      C++ .NET 2.0 Windows Forms application using Visual Studio 2005. I only
      create a new project, save and compile it and launch it. Thats ok on
      the machine where my IDE is installed. On a second computer i've
      installed the .Net 2.0 Framework ( exactly same version which came with
      the Visual Studio 2005 ). All i get on the second machine is a error
      box saying "Error executing program!" immediatly after clicking on the
      executable which is copied to the local harddisk of the second
      computer.
      
      I don't think this has anything to do with security policies since i've
      also disabled some of this security stuff by using "caspol -e off -s
      off".

    - Hiding TabPagesHi,
      
      Does anyone know how to hide certain TabPages inside a TabControl in VS.NET
      2003?
      
      I've seen code to remove the tabpage but I want to show/hide based on the
      user's access rights each time, rather than removing the tabpage.
      
      There doesn't seem to be an Enabled or Visible property and setting Locked =
      True doesn't seem to do anything either.
      
      Microsoft: this is basic functionality!!!
      
      Thanks in advance,

    - TypeConverter and Generic ListsHi I am having a bit of difficulty with TypeConverters and Generic Lists and
      I was hoping that I could get a bit of advice.
      
      I have a type converter that is used to create the constructor code for my
      component. (It is an XNA a Game Component, but I don't think that that has
      anything to do with the problem because it appears on a Winform) inside
      another component.
      
      For instance I have the following:
      
      public class A{
      private string s;
      public string SProp
      {
      get{ s = value;}
      set {return s;}
      }
      
      public A()
      {
      s = "";
      }
      public A(string inS)
      {
      s = inS;
      }
      }
      
      By itself, when class A is an object on a form (or in my XNA Component) the
      TypeConverter code works fine, the property grid on the desinger is fine, if
      I debug the ConvertTo on the type converter I see that the variable s is all
      set up okay on the object.
      
      However if on my form, I have a List<A>, the type converter works to an
      extent, as in it will add code to the perform the List.Add(new A("")),
      however the constructor with the parameter is not being called, instead the
      parameterless constructor is being called.
      
      Obviously, if the input to ConvertTo on the type converter is not set up,
      then my type converter won't work or display the values the user has put in.
      This only occurs when my object is in a Generic List.
      
      Any Ideas,
      Paul Kinlan

      and here is the code giving the problem:
      
      private void Button2_Click(object sender, System.EventArgs e)
      {
      // this code is used to prevent going to EOF
      if (!rs.EOF)
      {
      rs.MoveNext();
      if (rs.EOF)
      {
      rs.MovePrevious();
      }
      PopulateSimpleNavigationForm();
      }
      }
      
      Any help is appreciated.
      Thanks,

    - .Net Broadcastwindow 1.0.5I've got a c# app that causes a ".Net Broadcastwindow 1.0.5" event window to
      pop up when I shutdown the machine, it stops the shutdown. Has anyone else
      seen this, or figured out what could cause it? thanks
