    - Exception code: 3221225477 I am an Iraqi Veteran, and not too sharp when it comes to computers, and really a novice user. Microsoft suggested that I post a question to this forum, and hopefully I can get an answer to my difficult and annoying problem. I keep getting EXCEPTION CODE: 3221225477 EXCEPTION ADDRESS: 00502DD9 when I am either starting windows XP or working on something on my computer. I have tried to restrore the system, but the computer will not restore to an earlier date for some strange reason....... Heeeeeeeeeeeeeeeeellllllllllllllllllllpppppppppppppppp....

    - How can I detect if a program is started? I want to create my C# program to run in the background and detect when a program starts. In an interactive program, I know I can iterate through an array of Processes to find my process if I click a button, for example. But, I cannot find the best way to run my C# program in the background waiting for a program to start The program just needs to stay in the background and when someone say opens notepad, I can show a messagebox saying "You opened notepad." All I saw was a gigantic set of code with hooks. I don't know if that's the best way to do it. My purpose behind this is to keep someone from running a third party program more than one time because it is frying everything. One thought was to just start the program from my c# program, but I didn't like it. Someone could always bypass it and just start the program directly. Thank you for any help.

If I compile it as x86 my Virtual Drives are called "Virtual Drive" with an ImageIndex of 9 but compiled for x64 they are "CD Drive" with an ImageIndex of 7. Is this because the drivers for the Virtual Drives are 32 bit?

    - Unwanted behaviour on browser back button I have a registration form that updates a province/state droplist when a country is selected from another droplist. When the user clicks the back button though, the province list goes back to the prior country, but the country list remains the same. This would be ok if the country went back to the prior country as well. Ideally, I would just like the back button to just go back to the previous page that linked to the registration page instead. I tried playing around with EnableViewState a bit without success thinking that may have something to do with it. Below are some code snippets: aspx <tr> <td>Country</td> <td><asp:DropDownList ID="ddlCountry" runat="server" AutoPostBack="true" onselectedindexchanged="ddlCountry_SelectedIndexChanged"></asp:DropDownList></td> </tr> <tr> <td><asp:Label ID="lblProvince" runat="server"></asp:Label></td> <td><asp:DropDownList ID="ddlProvince" runat="server"></asp:DropDownList></td> </tr> aspx.cs protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { // Look up country info using (DataSet ds = NNRDReports.XMLHelper.GetDataSetFromXml(@"Xml\CountryInfo.xml")) { DataTable dtCountries = ds.Tables["Country"]; ddlCountry.DataTextField = "Name"; ddlCountry.DataValueField = "Code"; ddlCountry.DataSource = dtCountries; ddlCountry.DataBind(); ddlCountry.SelectedIndex = 0; CountryChanged(); } } } protected void ddlCountry_SelectedIndexChanged(object sender, EventArgs e) { CountryChanged(); } private void CountryChanged() { ddlProvince.Items.Clear(); // Look up what the country info and populate it into the page using (DataSet ds = NNRDReports.XMLHelper.GetDataSetFromXml(@"Xml\CountryInfo.xml")) { DataTable dtProvinces = ds.Tables["Province"]; dtProvinces.DefaultView.RowFilter = "CountryCode='" + ddlCountry.SelectedItem.Value + "'"; lblProvince.Text = (string)dtCountries.DefaultView[0]["RegionType"]; ddlProvince.DataTextField = "Name"; ddlProvince.DataSource = dtProvinces.DefaultView; ddlProvince.DataBind(); } } Tag: Listbox ite count change Tag: 568980

    - Installer choices. Last year I purchased Macrovision (now Acresso's) InstallShield 2008 product to create an MSI package. Without getting into details, I'll just say I've been very unsatisfied with the InstallShield 2008 product (stability, extensibility, cost of documentation, quality of support all factors). I'm not sure how robust my install process is relative to others, during the install a Windows service must be installed and a few files are written to windows system folders. During uninstall these steps must be reversed. I'd like to hear from those with experience with various installer packages. I'm looking for an option that's well documented (e.g. if I want the installer to execute .NET code during install, examples should be available on-line) also I'd like to know book recommendations for compiling an MSI package without the use of a tool (WYSE, InstallShield, etc..).

I've been away from daily programming since then and I've not done much with Windows and .NET development. I've done Access programming and some other vbscript based development. I'm back to coding and I will be working with Visual Studio 2008 Pro using C#. I am willing to work with latest technologies like LINQ and WPF. I will also be working with ASP.NET for a website. My question is: apart from Visual Studio 2008 what are the absolute tools you will recommend me to use? Those top 10 tools I will not be able to work without?

    - Writing a Custom BindingList for Mapping between DataObjects and Hello: I have a mapping class that can take generic data objects and locate/ add/remove/update DataRows in a DataTable. I associate them using attributes: TableAttribute and ColumnAttribute. I use reflection to move the data between the data object and the DataTable. I would like to make this extremely easy for my Forms developers. I would like calling AddNew() to call mapper.AddDataRow(dataObject). I would like changes to call mapper.UpdateDataRow(dataObject). I would like removing to call mapper.DeleteDataRow(dataObject). I am trying to implement this. Right now, I am inheriting from BindingList<DataObject>. However, I am not sure which methods to override and where to place my code. A quick example would be awesome. I get the impression this should be easy to do; I just don't know how to do it correctly. Also, I would like to know what is the best method for preventing the addition a bogus values to the BindingList<T>. How can I prevent them from adding NULL or and instance of U?

    - treeview performance I just learned of an IBM patent(7412649 ) awarded this month for a method of populating a treeview that improves performance by loading only the upper level nodes and loading childnodes only when an upperlevel node is expanded. Has not this method been around for at least ten years? I remember reading articles on it back in the VB6 days, but cannot locate them now. Anyway, just curious. The patent was filed in 2005 and there must be numerous examples of so-called "prior art" on this before that date. If anyone has a refernce to prior literatue or actual software, let me know.

    - Close() timeout in NetworkStream and Socket? I have an application that wants to open a Socket, write data and close the socket. A persistent connection would be nice, but it's intended to operate in an environment where the network connection probably isn't reliable. So I do this: // open socket m_networkSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint them = new IPEndPoint(IPAddress.Parse(hostname), port); m_networkSocket.Connect(them); m_networkConnection = new NetworkStream(m_networkSocket, false); // write m_networkConnection.Write(arrayOfBytes, 0, arrayOfBytes.Length); m_networkConnection.Flush(); // close m_networkConnection.Flush(); m_networkConnection.Close(); m_networkSocket.Close(); All fine & good, but nothing shows up on the other side. If I put a delay between Flush() and Close() it suddenly starts to work. So is Flush() is a no-op? Close() (for both Socket and NetworkStream) has an optional "timeout" value (an Int32), which is 'the amount of time to wait for data to be sent'. I _assume_ that's milliseconds, but does anyone know for sure? That begs the question, however, of just how long do I wait? How do I know my data has been sent and it's safe for me to close the connection?

    - Constructor Accessibility - protected ctor inside public class with Hello: I have a public abstract class. The concrete subclasses must pass an instance of an internal class to the abstract class' ctor. I like to make the constructors of my abstract classes protected. However, since it has a parameter that is of an internal type, I am forced to make it internal also. This is fine since no one outside my library can see it. However, I would prefer to restrict this even more, so that only subclasses can see the ctor. "protected internal" provides the relationship: visible to code within the library OR ANY subclasses. I want: visible to code within the library AND internal subclasses. I suppose there is no solution. I was hoping someone could give me some insight, however. Thanks, Travis P.S. - I can't make the abstract class internal since it implements a public interface and the subclasses are public. Tag: Listbox ite count change Tag: 568862

    - Deserialization issue I'm getting an error when deserializing my objects: "The ObjectManager found an invalid number of fixups. This usually indicates a problem in the Formatter." I added a new object to a class that gets serialized and put the OptionalField attribute on that object. When trying to deserialize my object in an older version of our application that doesn't have this new class I get the above error but that's only when items have been added to the class. The class looks like this: public class MyCollection : BindingList<MyClass> { } public class MyClass { private string mystring; private CustomEnum myenum1; private CustomEnum2 myenum2; } public class ClassThatGetsSerialized { string member1; int member2; ... ... [OptionalField] MyCollection mycollection; .... } The error only occurs if object ClassThatGetsSerialized is deserialized by an older version that doesn't have the definition for MyCollection and if the member of ClassThatGetsSerialized.mycollection has items in it. If there are no items then the error does not happen. We use the OptionalField attribute in many places and it always works fine. Any ideas? Thanks, Joe Tag: Listbox ite count change Tag: 568857

    - Need for efficient method for File Parsing and copying I am trying to update another developers code, and am stuck in a cludge. It works like this: A user uploads a file from the web page. Our code reads from a NetworkStream to a Filestream, and writes out a temporary file. Then the file is parsed (The file contains HTML data + the actual binary file that was transmitted). As part of the parsing, once the main binary file is to be parsed out, it is written with a new Filestream, byte by byte to a new location on disk. This was great when the file was 24Mb, but now it is 70Mb, and our windows CE device can not hold 2 copies of this large file. Not to mention that the additional copy takes a while to perform. To me it seams that there are two methods to solve this, the first being to read the networkstream realtime until the actual binary file shows up, then filestream directly. The second method, which to me seems simpler, is to just take the large temp file, and truncate off the non-binary data. By the way, I can not use a memorystream, as I have alocated most of the device memory to storage, thus there is not enough memory room. Anyone have any advice??

    - Linq Query. Please, help. Going crazy ... Hi, On a form I have an input where tags are inserted in a CSV format. Then on my code I convert the CSV string to a List<Tag>. Tag is an object with two properties: TagID and Name So when I do the conversion I only fill the Tags names ... Then I use a join to find these tags into my database.Tags and get their ID's.

And those names do exist in database.Tags. However, I always get the following error on my second query: Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator.

Why XmlDataSource does not have an implementation of DataSourceView GetView(string viewName) while it implements the interface IDataSource that defines it?

    - MarshallAs for char* buffer I'm trying to use some closed source unmanaged C++ dll. One of functions I have to call have signature as follows: int getData(char * buffer, long * bufflen); And this function requires that buffer is initialized to hold bufflen chars. bufflen after function is called will contain lenght of response data. If I try to marshall it using [DllImport("mydll.dll",CharSet = CharSet.Ansi)] public static extern int getData( [MarshalAs(UnmanagedType.LPStr)] out StringBuilder result, out long bufflen); i get acces violation exception, despite that string builder is initialized by: long bufflen 256; StringBuilder result = new StringBuilder((int)bufflen); DllMapper.getData(out result, out bufflen); What I'm doing wrong?

    - DataSource in form of Object Hello! In the Data Source Configuration Wizard I can choose Object as a Data source. It feel much more natural to have Database as the Data source. I feel very uncertain about having Object as the DataSource. Can somebody give me an good example when to use Object as the data source or a good page where I can read about that. //Tony Tag: Listbox ite count change Tag: 568778

    - text "variables" Hi sorry, this doesn't really have anything to do with c#, but I wasn't sure where else to post. I am writing some code which needs to parse some text (a string) which is to contain "variables" (special tags) which should be replaced with real values. For example, a variable called "CURRENT_DATE" or "USER_NAME". Is there any standard or best-practice for the syntax for this sort of thing? Like "As of today {%CURRENT_DATE%} your username {%USER_NAME%} is suspended..." Thanks, Peter -- Tag: Listbox ite count change Tag: 568771

None that I know of, but if you need that sort of thing, why not just
bind the list to some collection (e.g. BindingList<T>) that can be
subscribed to?
