    - Assembly Version In the 1.1 framework the assemly Version would optionally auto-increment. In the 2.0 framework the auto increment seems to be only available on one-touch deployment. How can I put auto-increment back on a non-one-touch assembly?

    - Slow loading of file icons Hello I've got a problem with loading file icons to TreeView. I'm diplaying only some directories in TreeView (~50 files total), but it's taking a long time to add them. Loading is done by [DllImport("Shell32.dll")]...SHGetFileInfo(...) and it's fast enough, but then doing ImageList.Add(...) is taking up to a couple of seconds for ~20 icons, which is really bad. Is there any way to help it? (no delayed loading on expand event and this kind of stuff, please - it's only about adding (string, Icon) to ImageList). Writing in c#...

    - CounterSample & nextSample I need to produce the 5 minute average CPU utilization for a system (the average utilization over a 5 minute period). I found the below article that seems to do a reasonably complete job of explaining the differences between raw, calculated and sampled performance data. http://msdn2.microsoft.com/en-us/library/xb29hack.aspx CPU utilization is of type Timer100NsInverse. So here is my question: to get the most accurate 5 minute average of CPU utilization, should I be taking a sample at 0 minutes, another sample at 5 minutes, and then calculate the results (see below code for an example)? Advice would be appreciated. Thanks in advance. Joe // 1st sample counter = new PerformanceCounter("Processor", "% Processor Time", "_Total", "192.168.130.9"); sample1 = counter.NextSample(); counter.Close(); Thread.Sleep(5*60*1000); // 2nd sample counter = new PerformanceCounter("Processor", "% Processor Time", "_Total", "192.168.130.9"); sample2 = counter.NextSample(); counter.Close(); // Output results Console.WriteLine("CPU util = " + CounterSample.Calculate(sample1, sample2)); Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113949

    - Equivalent to VCL's DataModule In Borland's VCL ( Visual Component Library ), one can use a DataModule into which one can drop non-visual components from the RAD designer. The DataModule is a design-time visual container for non-GUI components, which is never seen visually at run-time as a GUI control. An application or Dll can have any number of datamodules in it, each with its own name. One can also manually add any non-GUI data to any particular DataModule. For an application at run-time, datamodule instances for each visual datamodule are automatically created just like forms, while for a Dll at run-time it is the programmer's responsibility to create datamodule instances for each visual datamodule created at design time. I have found the ability to use datamodules as visual containers to non-GUI components in an application or Dll to be very useful. Admittedly a datamodule is nothing more than a class which contains instances of non-GUI components and possibly other non-GUI fields, but I like the ability to manipulate it at design time, and as a means of separating the data portion of an application or Dll from the GUI portion. Does .NET have any equivalent to this idea, so that non-visual components can be created at design time without having to drop such a component on a Windows or Web form. ?

    - UTF8 to UTF16 ? I'm somewhat confused about Unicode but up until now I havent really seen much issues with using it up until recently. We recently started using an SMS gateway that requires a unicode message to be sent as a hexadecimal string where each byte code has been replaced with their hexadecimal value, for example: 043104AF0442044D044... This string according to their documentation must be in UTF-16 before conversion to the hexadecimal form, we however are using UTF-8 on our website and all the texts are entered as UTF-8. When I try to send a unicode formatted message using content from our website it shows some characters correctly but not all of them, I cannot see another reason for this than the fact that we are using UTF-8 and they require it to be in UTF-16. Now to the questions: 1. How do I convert between UTF-8 and UTF-16 ? I was looking at the Decoder, Encoder classes but it doesn't really provide a direct way to convert between encodings that I could see. 2. Since all strings are actually UTF-16 in .NET does this mean that the conversion already has been made or does it mean it is actually storing UTF-8 encoded bytes into a UTF-16 string ? Thank you PL.

    - Additional component to web service I post here is because there is no one answer my question(10 days ago) in "web service" news group. I am going to implement a program on the web service side. The program will work with the web services so that it can do some check on the data before invoking any web method. The program will do some general checks, and does not know exactly what kinds of web methods behind. I think I could write a dll, then let the web services to call this dll first before the web methods are invoked. But I do not how to do exactly. Is there any way to integrate the program into the web services? Please give me a guide in details. Thanks. Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113944

    - help: simple csc works in 1.1 but not 2.0 framework I'm pulling my hair out! Is this a bug?? Scenario - boiled down as simple as I can make it. 1. Created 2.0 console app. 2. Added reference: (COM tab) "Microsoft CDO for Windows 2000 Library" ---- This adds CDO and ADODB references to the project 3. Added a few lines of code (see below) 4. Compiles just fine from VS 2005. (puts Interop.CDO.dll and interop.ADODB.dll in debug dir. 5. If I copy the code and the Interop.CDO.dll and interop.ADODB.dll to a single directory and run csc on it, framework 1.1 csc compiles fine, 2.0 csc gives errors acting like the ref is not there.

    - how to interpret Number property in System.Data.SqlClient.SqlError Environment: .NET 1.1, SQL 2000, VS.NET 2003. We have some logic in an application to perform some recovery operation on the client side based on the SQL error code returned from System.Data.SqlClient.SqlError. It seems to me that the Number property in System.Data.SqlClient.SqlError is a perfect fit. According to the manual page, The Number property in System.Data.SqlClient.SqlError corresponds to an entry in the master.dbo.sysmessages table. I managed to get some numbers not listed in the master.dbo.sysmessages table: 11 (General network error. Check your network documentation), and 17 (SQL Server does not exist or access denied). It is reasonable that these network related errors do not appear in the master.dbo.sysmessages table. However, I was wondering, in addition to 11 and 17, what are other possible error code (returned by Number property in System.Data.SqlClient.SqlError) not listed in master.dbo.sysmessages table??? I remember that ODBC (in unmanaged C/C++ code) has very detailed description for EACH error code and sql state, and people always suggest that we use System.Data.SqlClient instead of System.Data.Odbc. I already tried MSDN as well as google various places without luck. Or is there any other way to do what I wish to do? Any hints/suggestions are appreciated. Thanks.

    - Remoting a collection class? I want to create a collection class (List or SortedList, etc) that is remotable (inherits MarshalByRefObject). Because C# doesn't support multiple class inheritance I can't just do this: public class Groups : List, MarshalByRefObject I know I can implement all of the collection interfaces myself but what a hassle. Is there a simpler way? Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113926

    - .NET 2.0 application stop serving ASPX pages? I've set up a development ASP.NET 2.0 application folder on a development server. This folder has been set up since at least January, and I have been working in it myself since February 2nd. It has been working fine up until this week. Three times this week it has locked up and no longer serves up .NET page requests. You can still access the files there through Windows explorer, and it still will serve non-.NET files such as ASP pages or text files through the browser, but it will not serve up any .NET ASPX pages. Even if the code inside is recompiled, or new pages are added, they are still not served up. I have eliminated any code-related issues on this, and have confirmed that if I restart IIS, then it starts working again. This did not happen for the past six weeks at least, but this week it has happened three times in four days. The lock-up today happened when I made a change to a web.config file but did not re-compile or anything, and when I hit the site again, it was doing this. I have made other web.config changes this week that did not cause this problem. Anyone else having this problem or know what is causing this?

    - Printing Anomily Hi, I have a problem that I recently solved and thought I would throw it out to see if anyone can explain why I had to use the particular solution. I have an application that prints a series of numbers to any printer. It was developed in C# for .NET 2.0 Framework. The code looked like this //variable to hold the last Page and Print settings private PageSettings lastPageSettings; public FormMain() { InitializeComponent(); lastPageSettings = new PageSettings(); } private void runToolStripMenuItem_Click(object sender, EventArgs e) { PrintDocument pd = new PrintDocument(); FormNumberer thisForm = (FormNumberer)this.ActiveMdiChild; pd.PrintPage += new PrintPageEventHandler(thisForm.RunPage); pd.DefaultPageSettings = lastPageSettings; printDialog.Document = pd; if (printDialog.ShowDialog() == DialogResult.OK) pd.Print(); } Here is the issue. The above code works fine on a Wndows XP Machine. When the application is copied to a Windows 2000 Machine and executed I get a memory error at the line pd.Print(). Now while debugging I observed that the PrintDialog placed the printer settings into pd.PrinterSettings, but not into pd.DefaultPageSettings.PrinterSettings. So therefore the two variables would contain different printers if the default printer was not used. So I made this adjustment: if (printDialog.ShowDialog() == DialogResult.OK) { pd.DefaultPageSettings.PrinterSettings = printDialog.PrinterSettings; pd.Print(); } And now everything works fine. Does anyone have a clue as to why this may be? Thanks, Bryan Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113905

    - Help! OnClick event in VScrollBar in .Net Compact Framework Hi! I tried to catch the Click event from a VScrollBar control but the Click event is not rised. MSDN says that OnClick event is suported by .Net Compact Framework and, in this case, I supose that the click event sould be rised bu VScrollBar. In this case I derived a class from VScrollBar and I overrided the OnClick protected method. I failed again because the overrided OnClick method is never called. I derived another class from Control and I overrided again the OnClick method. In this case the overrided OnClick method was called. Please, there is anybody who can tell me what is happening with OnClick method and Click event for VScrollBar control? And what should I do to catch the Click event for VScrollBar? Or what should I do to make it work OnClick overrided method in a derived class from VScrollBar?

I have the code working on my development machine. But when run on a different machine (or same machine with another account), it fails with a System.UnauthorizedAccessException. I presume it is because on my dev machine/account my account is a member of the Administrators group and on the other machine/account it is just a normal user. But I need to have the code work for a non-admin user (basically any user). What do I have to request to get this level of permission and how do I get it? Thanks.

This is a problem for me, because I am using managed code to write a OWC spreadsheet addin, and memory allocated by the addin is not freed when the spreadsheet is destroyed. I wanted to explicitly invoke InteropServices.Marshal.ReleaseComObject, but it is failing, presumably because the object returned by CreateObject() is, in some way, not a COM class.

    - "unable to write data to transport connection" error Hi everybody. Yes, I know there are a number of posts about this, but many of them have not been answered and of those that have been, I can't find one that exactly fits. I am working in vb.net using a TCPClient object and sending commands to a remote, IP-aware device. All goes swimmingly for a while, then I get the above error. The exception's "InnerException" is a "SocketError", with the message, "An existing connection was forcibly closed by the remote host" It's usually about 5 minutes or so before it gives up. The client who owns the device says another version of our software connects fine all the time, via a serial-to-ip conversion device/program. So it's unlikely to be the device itself, despite the inner exception message. I have tried both send and receive timeouts on the TCPClient - no change. I am at a loss - any ideas out there?

    - System.Configuration.Install.Installer and console I have a Windows service exe that derives from System.Configuration.Install.Installer The exe can be executed from the command line with parameters such as INSTALL, UNINSTALL, START, and STOP to perform such tasks on the service But the exe is also the exe that _is_ the service process, so when it's run with no parameters (by the SCM?) it calls System.ServiceProcess.ServiceBase.Run ( srp.ServicesToRun ) ; The problem then is when it's accidently run with no parameters from the command line. Is there some way for it to know whether or not it's being executed by the SCM? I'd like it to be able to give a help message and terminate when it's run from the command line while still behaving properly when running as a service.

    - INSERTing long TEXTs into MSSQL 8.00.2039 Hi, I have a table with columns of types datetime, varchar, text, text, text, text. The text columns will contain XML documents, there is no primary key in the table but they varchar column contains foreign keys. If I insert trivial text values like "hello" everything works fine but when I use real XML documents weird things start to happen. The row gets inserted with no error message but when I view it in enterprise manager the particular column that was supposed to contain the XML document is empty (the datetime and all text columns with trivial values like "hello" or "world" is correctly displayed). After some experimentation I noticed that it appears to be the length of the text field that determines whether that column will get a value or not. For text values of length 900 chars and shorter it's no problem, but for text values with a length of 901 chars that column will not be set but instead empty. The actual content of the long text value does not matter, I tried to insert a 900 char string of the letter "c" only and that worked, while 901 consecutive "c" chars causes the row to be inserted with a empty value where the string of "c"s should have been. My question is, how can I insert TEXT values longer than 900 chars? I know this datatype should handle alot longer values... FWIW; I'm using MSSQL 8.00.2039 and I'm doing the INSERTs using standard .NET component (ver 1.1) such as SqlConnection and SqlCommand. regards, martin Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113850

    - Generic Lists Desing Issue Generic Lists are great! But I think you missed a opportunity. Here is my problem. I made a Collection "Family: List<Person> " which will contain 'Family'. I wanted to override the Add method so you can only add persons whose Parents or Childeren are already in the list, but the Add method is not virtual! The Add method of Arraylist is virtual and I see no reason for the generic counterpart not to be. My work around is to create my own GenericList that has a private List<T> and duplicate all IList<T> members and make them virtual, but still it should have been there all along. I see no reason why List<> or all other generic collections have no virtual methods, is there? Maybe speed, but that wasn't an issue with ArrayList so it shouldn't be with generic collections either.

    - Threading problem in local COM server We have defined a COM object in C# on the .Net platform (v2.0.50727) in an out-of-process server (.exe). This COM object, in one of its methods, creates a WebBrowser control (AxSHDocVw.AxWebBrowser). The main application can successfully create an instance of this object, but when trying to call the method creating the WebBrowser control, an exception is thrown stating that System.Windows.Forms: ActiveX control '8856f961-340a-11d0-a96b-00c04fd705a2' cannot be instantiated because the current thread is not in a single-threaded apartment. The Main() function in the COM server has the [STAThread] attribute set, and we checked that this thread actually runs in a single thread appartment. The constructor of the COM object is also called on this thread, in STA. The method creating the web browser control, however, is called on another thread, which indeed runs in MTA. We did not create this thread, nor did (willingly) specify somewhere that a thread should be created, and so we do not have control over the apartment of that thread. I don't know whether it is relevant, but the class factory of the COM object is registered with the flags CLSCTX_LOCAL_SERVER, REGCLS_MULTIPLEUSE, after which the Main() function goes on to accept COM requests by calling System.Windows.Forms.Application.Run (); I'd be very grateful for any clues or hints.

    - Decimal/Single/...: which Numeric-type to use? Hi, I'm having some troubles with my numeric-types in my VB.NET 2005 application, together with a SQL Server 2000. - I first used Single in my application, and Decimal in my database. But a Single with value 4.475 was converted to a Decimal with value 4.4749999999999996D. So after inserting and selecting it from the database I got another value than the original! - So I used also the Decimal in my application, but now all my numbers are formatted with all the decimals: when my value is "1", it shows "1.0000". A single value roudns it nicely to 1, but the decimal value shows the whole decimal part, even when it isn't needed. What I need is: the users should only see the decimal part when needed, AND my values have to be the same (no 4.475 to 4.474999999999 changements). This seems such a simple and basic need, but I just keep having troubles with it :-( What should I do/use? Another numeric datatype in my application? Another datatype in my Database??

At design time, I do not know if internet explorer/netscape is installed on the client machine. The C# code should identify that and open. Please help.

    - Page state on postback Hi, This is a pretty straightforward question about postback, etc. in C# ASP.NET. I have 3 DropDownLists, each is bound to a SQL DataTable, created from 3 SQL queries. If the user makes a selection from a DropDownList, an auto-postback event is triggered. But, the DataTables, which are members of my Page class, become null on the postback. I don't want to lose that DataTable information. There's more info in the DataTables than the DropDownLists, which is why I want to keep them around. So, does this mean I need to recreate the DataTables somehow and rebind , such as repeating the SQL queries and rebinding, or serializing the data somehow? I'm just trying to figure out the limits of what .net does for me. Is it limited to setting the state of controls on postback? I'm aware of how Session["var"] and ViewState["var"] work, I just wanted to see if I'm overlooking something, like some trick to keep variables in the Page class around between postbacks. At this point it seems like caching the SQL queries to recreate to DataTables is my best bet. Lemme know if I'm missing something. Thanks in advance Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113816

    - Can't cancel the validation when the control lost focus to a userc I have problem with a control when its causesValidation property is set to true. It is actually happens in .NET Framework 1.1. When I lost focus from this control to another control within a user control by clicking the target control, I can't really cancel the validating event. It won't happen if I move the focus to other control within the form, or within the same container of the source control. another different behavior when the application is ran in Terminal Server. + Steps to Reproduce: Let say the source control is a textbox and the target control within a usercontrol is a checkbox. When I click the checkbox, the checked value is changed and so does the validating event of the source control. So, the focus remains in the source control, but the target control is excecuted too. Sample application is in: http://www.geocities.com/dikhi/downloads/WindowsApplication2.zip + Actual Results: In Windows XP: The focus remains in the textbox, but the checked value of the checkbox is changed. In Terminal Server: The focus is moved to the target control. + Expected Results: In WIndows XP: The focus is still in the source control (already correct), but The target control (checkbox) shouldn't change its checked value. In Terminal Server: The same as the Windows XP Many thanks in advance. Tag: Good introductory C++ .NET book, preferably for VS.NET 2005 (or 2003) Tag: 113814

Anyone have good suggestions? I have loads of experience with C# and
VB.NET, but would like to make the transition to C++.

Thanks!
