    - unconfigurated applications&framework version In the article "Side by Side Execution of the .NET Framework http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnnetdep/html/sidexsidenet.asp I read that Windows client applications without configuration file execute with the Framework that was used to build the application, provided that the framework is installed on the local system. When that version is not available. the CLR uses a later version of the framework. But which version will it use if there are 2 or more later versions installed?

    - XML Serialization Weird Exception I was testing XML Serialization to assess if it fits my needs. I coded two methods, one dumping the XML serialized object to a file, and the other that recreates the object: static Graph Awake(string filename) { System.Xml.Serialization.XmlSerializer s = new System.Xml.Serialization.XmlSerializer(typeof(Graph)); System.IO.TextReader r = new System.IO.StreamReader(filename); object res = s.Deserialize(r); r.Close(); return (Graph) res; } static void Hibernate(string filename, Graph graph) { System.Xml.Serialization.XmlSerializer s = new System.Xml.Serialization.XmlSerializer(typeof(Graph)); System.IO.TextWriter w = new System.IO.StreamWriter(filename, false); s.Serialize(w, graph); w.Close(); } If I run those methods separately, they work fine. However, if I run Hibernate and then Awake, Awake throws an exception... Furthermore, if I command Hibernate to dump the XML data to a file other than the one Awake is going to read from, Awake fails again with the same error. Any ideas? Bug? Regards, Manuel.

    - XML Serialization problems related to framework versions Hi all I get an exception when trying to deserialize a simple configuration file using XML Serialization. The very long stacktrace can be seen at the bottom of this message. I've see other messages related a similar error but none of the solutions suggested are valid in case :/ I have tracked the problem down to the compilation of the temporary DLL that handles the actual serialization. The following commandline (that is one single line) is executed by the framework when trying to deserialize my configuration: "c:\windows\microsoft.net\framework\v1.1.4322\csc.exe" /t:library /utf8output /R:"c:\windows\assembly\gac\system.xml\1.0.5000.0__b77a5c561934e089\system.xml.dll" /R:"c:\program files\MyApp\MyConfig.dll" /R:"c:\windows\microsoft.net\framework\v1.1.4322\mscorlib.dll" /out:"C:\DOCUME~1\User\LOCALS~1\Temp\i2_6axn4.dll" /debug- /optimize+ /w:1 "C:\DOCUME~1\User\LOCALS~1\Temp\i2_6axn4.0.cs" Note that it uses the .NET 1.1 compiler and core lib but references the .NET 1.0 XML assembly. The result is that the assembly isn't created and hence cannot be loaded. I've specifeid the required runtime version in the .config file to be .NET 1.1 without any improvements. The problems occur on a Windows XP test machine with both .NET 1.0 and 1.1. The application is built using VS.NET 2003 on a machine with only .NET 1.1. The user running the code on the test machine has administrative rights. I've have tried the XmlSerialization precompiler and it works without problems... Anyone have any ideas why this happens? Kind regards, Hakon Exception: System.Configuration.ConfigurationException: Unable to load configuration from the XML configuration file: 'C:\Program Files\MyApp\MyApp.exe.config'. This can be caused by a number of problems, but the most common problem is an incorrectly configured Updater configuration file. The most probable sources of error are: missing nodes, incorrect attribute names, white space within attributes or within elements, white space between elements in the same sub-node, badly formed xml, or xml that does not conform to the ConfigSchema.XSD. ---> System.Configuration.ConfigurationException: Exception in configuration section handler (C:\Program Files\MyApp\MyApp.exe.config line 16) ---> System.IO.FileNotFoundException: File or assembly name _zdvwu31.dll, or one of its dependencies, was not found.

    - Posting using httpwebrequest Hi, Should the form submit button click event handler fire when posting to a aspx page using httpwebrequest. In my tests the load event fires when POSTing back but not the button click event handler. I first issue a GET, extract __VIEWSTATE and then POST back __VIEWSTATE and the form values. I am hoping to use this technique for a screen scraper but if I can't get the submit buttons click event handler to fire its no use. Thanks, Pazza Tag: How do I get hWnd in a .NET service with no UI?

    - Login for Hotmail Problems Not sure if this is the correct forum or not, if not, please advise. Have recently noticed that when I sign on to my hotmail account, I am directed to a screen asking me to type my password. It has the correct e-mail address listed and the box "Sign me in automatically." is checked, but the password field is blank. The other box ("Do not remember my e-mail address for future sign-in. (Select this when using a public computer.)") is not checked. If I simply click at the bottom on "get one now" I am told that "You Are Already Signed In". If I click on the "Return to Hotmail" link I go immediately to my hotmail account. How can I avoid taking these extra steps each time? If I am already signed in, then why can't I go directly to my hotmail account? Thank you in advance... Tag: How do I get hWnd in a .NET service with no UI? Tag: 91816

    - what is best practises for sending out emails from .net? What are the best practises people have found for sending out emails with their web apps in .net? I've read a few places that talk about using the System.Web.Mail namespace. But I think that namespace requires an SMTP server does it not? And if it does, do people redirect the SmtpServer to their own email servers or to IIS SMTP service and have it use SmartHost to goto their email server, or just have IIS forward the emails on? I'm sorry if this has been covered before, I'm just getting into this now and would appreciate some ideas on what you guys/gals have found that worked. Thanks.

    - problem registering some file extension in winXP shell Hi: I'm trying to register some file extension in the system (.abc). According the documentation the next example should be enough, but my result is that the icon of my application appears on the Windows explorer with the files, and the description too, and the files are associated with my application correctly, but int the "Open With" submenu, and in the dialog used to select applications, there is only an Icon, the name of the application does not appear. I also have realized that the problem appears only with a .net exe file. Even creating a new .txt file and renaming it to .exe, "Open With" shows the name of the "application", but if the command key is set to a path pointing to a .net exe file, only the icon is showed. what have I missed? According to the documentation (wich is not specific to .net applications): HKEY_CLASSES_ROOT .abc = MyApp.abc.1 MyApp.abc.1 = MyApp document DefaultIcon = "c:\MyApp.exe",0 shell open command = "c:\MyApp.exe" "%1" //CODE: string extension = ".abc"; string description = "MyApp document"; Microsoft.Win32.RegistryKey rkey = Microsoft.Win32.Registry.ClassesRoot; rkey.CreateSubKey ( extension ).SetValue("", "MyApp" + extension + ".1" ); rkey = rkey.CreateSubKey( "MyApp" + extension + ".1" ); rkey.SetValue( "", description ); rkey.CreateSubKey("DefaultIcon").SetValue("", "\"" + Application.ExecutablePath + "\",0"); rkey = rkey.CreateSubKey("shell"); rkey.CreateSubKey ( "open" ).CreateSubKey ( "command" ).SetValue ( "", "\"" + Application.ExecutablePath + "\" \"%1\""); Tag: How do I get hWnd in a .NET service with no UI?

    - .NET Framework 1.1 Configuration won't launch I get the following error when trying to launch the .NET Framework 1.1 Configuration Snap-in: Snap-in failed to initialize. Name:.Net Framework 1.1 Configuration CLSID:{1270E004-F895-42BE-8070-DF90D60CBB75} Clicking 'OK' on the message box allows the MMC to start, which displays the following message: Snap-in Creation Failed. The snap-in is not created, it may not be installed properly. If I open an MMC console and try to manually add the .NET Framework 1.1 Configuration snap-in, the MMC hangs when I select the snap-in from the list of Available Standalone Snap-ins and click "Add". The MMC must be killed with Task Manager. I'm running Windows XP SP2. It's a new Dell Optiplex that came preconfigured with .NET Framework 1.1 eight weeks ago, but our domain has a GPO that installs .NET framework 1.1 on client workstations. This resulted in the .NET Framework appearing twice in Add/Remove programs. I couldn't be sure which resulted from the GPO, so I uninstalled one, and had to remove the other entry via the registry. Then I rebooted so the GPO would reinstall the .NET Framework. It shows installed, but will not run. The relevant registry key reports that my .NET 1.1 SP level is SP1. No programs that rely on the .NET framwork will run. Any help appreciated. Thanks, Bryan Tag: How do I get hWnd in a .NET service with no UI? Tag: 91788

    - Bursty data - SendBuffer TCP socket .NET, use messaging queue? Hello I am developing an application that sometimes ends up sending a large burst of data on the socket. My understanding is that the kernel will drop queued data randomly if the Send Buffer is overwhelmed with data. In order to prevent this there is the "SendBuffer" (One of the the enumeration values in SocketOptionName - http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemnetsocketssocketoptionnameclasstopic.asp I have not been able to determine the largest possible value that SendBuffer can be assigned; I really doubt if it is unlimited upto the system memory. I am hoping to get information about platforms running *WinXP* as well as *CF* so I am placing the post on both the groups. Extrapolating the question, *if* the SendBuffer is limited to a few tens of kB then is there a built in queueing mechanism to make sure that data trickles into the TCP connection when the burst comes? This is a real-time app (with almost gaming like requirements) so I am not sure if using a messaging queue would be very useful because the messaging queue stores stuff on the hard-disk sometimes. Anyone had any experience with these type of issues? Thank you very much for reading. -Jumu Tag: How do I get hWnd in a .NET service with no UI? Tag: 91784

    - Microsoft: Help with OLE documents... Hi all. I have an application to draw and design different documents, that supports linking and embedding of other documents (like, for instance, Corel Draw or Word). Then, the user can print their designs "WYSIWYG", so I load the external document inside an OLE document container control (VB6), get a handle to the object and invoke OleDraw with the hDC that I want the object in. This have been working excellent, and this application is largely distributed among our clients. The problem is we want to migrate to .NET (any language, VB, C#, C++, ...), but there's no OLE container that lets me obtain a handle to an OLE document. I know you could import COM and ActiveX, but this particular control (included in VB6) CANNOT BE IMPORTED NOR INSERTED in .Net. Microsoft calls this a "migration issue" and warns us about it, but how, then, can I draw an Ole document inside our application (let alone open, edit, update, etc)? Is Microsoft planning to update this component for VS.Net 2005? Or is there an alternative? I know I could load an OLE document "the hard way", but those are methods so obscure, I get lost before even starting to insert the document in a container... If this is the only solution, is there an easy (as easy as this can be) example that can lead me to accomplish the insertion of a document inside mine? I know it can be done, because RTF editor lets you do it. It even lets you open and edit the document, and "paste special", but I don't seem to accomplish getting a handle to any of those inserted objects... Thank you for your time, VBen.

    - VS 2002 and Framework 1.0/1.1 SP upgrades This is a question regarding service packs for the .NET Framework. We are still using Visual Studio .NET 2002 development environment to write our ASP.NET apps. However, on our app servers we also have .NET Framework 1.1 installed. Our current versions of framework offerings are 1.0 SP2 and then framework 1.1 with NO service pack. I know that as far as coding against the .NET Framework goes, since we are using VStudio 2002, we are coding against the 1.0 Framework. So my question is, when there are new Framework service packs released, do we need to only install the 1.0 SPs since we are coding with VStudio 2002? Or do the latest 1.1 framework SPs essentially rollup all the 1.0 changes? Since we code against the 1.0 Framework, just seems upgrading 1.1 service packs wouldn't do anything. Right now the 1.0 Framework is up to SP3 and the 1.1 Framework is up to SP1. I just want to know if I only need to install 1.0 SP3, only 1.1 SP1 or both.

    - Simple: Excel Jet 4.0 Link vb 2005 I need to link an excel file to a VB.Net program, so that the host computer doesn't need excel on it to read the cells. I don't need any functions of excel, just values from cells for viewing in textbox's. I am trying to link the file using the database explorer, but, after right clicking and selecting new database ole connection, then Jet 4.0 and the file name, I am being told that : "Could not find installable ISAM" I have looked on the newsgroups, and I have made sure that I have the latest versions of the Jet 4.0 installed I have the latest service pack, Office 2003 and VB 2005 express beta1. I'm thinking that maybe this a bit of a bad combination?? Tag: How do I get hWnd in a .NET service with no UI? Tag: 91744

    - ENTER and forms Can I use ENTER to submit my form using C#? I have used Page.RegisterHiddenField("__EVENTTARGET", "btnFind"); This works SOMETIMES but not all the time. I saw http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformsformclassactivatedtopic.asp and http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwindowsformscontrolclassgotfocustopic.asp which explains that ENTER is not used since the Activate is used for Forms. I understand the logic but I still cant get my forms to always submit on ENTER and instead it uses the first control (a list) and ends up being redirected. Enter has been used for decades to submit a request dating back to "dumb terminals" and even typewriters. So it makes sense to use the ENTER to submit forms.

    - Help for SocketOptionName.PacketInformation Hello, need aynone knowing something about the SocketOptionName.PacketInformation! Background: I have a little app sending and recieving ICMP-Echo and Echo-Replies. Now I wonder if it's possible to determine the MAC-Address of the answering Machine. After searching in MSDN-Library I found the SocketOptionName.PacketInformation and thought it could give me some details of the recieved pakcet. Now I'm trying to implement it but it doesn't gave me information at all. I tried a socket.getsocketoption() with an predefined byte-Array but afte the call the byte array is empty. So is there anybody able to tell me how to use this SocketOption correctly? Or does anybody know how to retrieve the MAC-Address from the Echo-Reply-Packet recieved by my socket? looking forward for the solution ;-)))) Tag: How do I get hWnd in a .NET service with no UI?

    - How does IIS or Framework set the Content-Length header ? Hello, I'm experiencing a strange problem with an aspx page. This page does NOT set the Content-Length header. When hosted on my development PC (with IIS 5.0 and .Net 1.1), the HTTP response however contains a Content-Length header. When hosted on our test server (IIS 5.0 and .Net 1.1 as well) the Content-Length is not set, causing the server to send the response (roughy 10KB) in several chunks which seems to dramatically decrease performances. My questions are: - How does IIS (which layer or component and with which algorithm) sets the Content-Length for a dynamic page ? - Which conditions would make our test server not to fill this header hencing causing (I guess so) this chunked encoding response ? Any thoughs or idea ? Thanks in advance Arno Tag: How do I get hWnd in a .NET service with no UI? Tag: 91739

    - mscorwks.dll I have an application that runs for about 1 minute before an exception window comes up saying: SV_TpeConsole.exe - Application Error The instruction at "0x7931529c" referenced memory at "0x00000000." The memory could not be "read". The .Net debugger only gives the assembly code. Is there a way to find out the call stack for this error or some other more useful information? None of the timers in the program are invoking this error, as they have been checked. Tag: How do I get hWnd in a .NET service with no UI? Tag: 91731

    - .net and mysql join i'm curious if there are any known issues with the 2. i've tried it in vc# and vb and i get the same results with both. every time i run a join and it gets to a 0 or null it makes everything following it in that column null. the mysql statement is: "select customers.name, customers.firstname, customers.customerid, customers.contact, customers.memorec, extinfo.info, memos.memo from customers left join extinfo on customers.rec=extinfo.rec left join memos ON customers.memorec=memos.rec where customers.rec=extinfo.linkrec and extinfo.identifier=1 and extinfo.primarytype=2 and customers.inactive=0 order by customers.name asc" the memorec points to the coresponding rec in the memo file. the problem is that if a customer has a 0 memorec (no memo) then the dataset makes it null and all the memos following it. is this a known bug or am i doing something wrong? is there a better way to do this?

    - .NET error using Group Policy Management Console? I make extensive use of Group Policy on our SBS 2003, so a few weeks ago I finally installed the Group Policy Management console snap-in on my XP Pro SP2 workstation. I've been successfully managing Group Policy via this console, but today when I selected a GPO and clicked the Settings tab, it hung on the message "Generating Report..." for much longer than usual, and finally displayed the following error message: "An Error occurred while generating report: File or assembly name System, or one of its depedencies, was not found." Efforts to run down this message mostly lead to discussions of version errors with the .NET framework that I don't completely follow. However, I tried uninstalling and reinstalling the .net framework, and checking my service pack level (I thought I might have applied .NET Framework SP2, but it doesn't appear to be installed on my system). I'm not sure what's next. Should I try uninstalling and reinstalling the GPM console? I'd rather not work blindly, so I don't want to try too much until I have a better idea of what went wrong in the first place.

    - I need some help with remote acces to a help file I have a program that is resident in the web server. It is one-touch installed on the client system and it is activated via URL so that it runs in IEEXEC. This program has a .chm file associate with it. The problem is 1) - Every time I try to reference the .chm, I get a dialog warning me that .chm files might not be safe and ask if to continue 2) - When I do continue to access the .chm, none of the positioning to the different TAB (index, search, contents) work, but if the same program is run from a command line from the same directory, this positioning works. 3) - Of course opening the help with a position to a keyword does not work either. Question. What is the best method for utilizing help files when the help file is remote to the system the program is being run on? ------------------------------------------- Roy Chastain KMSystems, Inc.

    - StreamWriter.close() hangs in multithreaded execution I've got a program accessing a HTTP service to get som XML data. The code receiveing the data looks something like this: stream = new StreamWriter(httpRequest.GetRequestStream(),Encoding.UTF8); stream.Write(body); stream.Close(); The httpRequest is a HttpWebRequest object. This works fine from a single thread execution, but when I'm accessing this method on its own thread, the Close() method seems to hang. Any ideas as to what I'm doing wrong? Jan -- Do or die..

    - what is the best way to read text file Dear sir/lady, I need to process our web server log file every day. Normally, this file is about 50MB - 100s MB big. How can I read the file in a effective way. I can open a streamreader to read it and use readline() function to read line by line and process them. However, this sounds very slow. I can also use readtoend to read everything into a string, but then I am afraid that it will be too big for memory. How should I read the file? Tag: How do I get hWnd in a .NET service with no UI?

I have a 3rd party library that requires a non zero hWnd parameter as a
parameter to one of it's functions. I need to ue this library in a Windows
Service with no UI. What .NET class should I use to create a simple
invisible window so I can pass it's hWnd to the 3rd party API? In the .NET
Compact Framework, I would use an instance of the the MessageWindow class,
but that class is not available except in the CF version. Do I have to call
the Win32 APIs directly to create a hidden window in a service? Has anyone
already wrapped this functionality and published it? Any suggestions?

Thanks,
Dave
