    - Diff between WebBrowser Component and AXWebBrowser I'm looking to user a web browser component in VS2005. I like the functionality in the AXWebBrowser component (from ActiveX controls page) that allows me to do this: mshtml.HTMLDocument doc; doc = (mshtml.HTMLDocument)this.SecureWebBrowser.Document; mshtml.HTMLButtonElement ButtonTest = (mshtml.HTMLButtonElement)doc.all.item("ctl00$CenterContent$ctl09$SignUp", null); ButtonTest.disabled = true; Is this possible with the WebBrowser component that I can drop onto my WinForm in VS2005 - I do not see that capability exposed - what are the advances/disadvantages of each? TIA! Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109894

    - FileStream Encrypted Impersonation Problem Object of the excersize: I have a service that needs to connect to securly to remote sevices. I need to be able to store the login information for the remote services in a secure manner. To do this I was going to create an encrypted file containing the login information. Encrypted under the service's login account. I want to edit this file with a setup program. My idea was to have setup program propmt the user to "login" as the service account and impersonate this account while writing the config file. The basic flow of the code is this: LogonUser(sUsername, sDomain, sPassword, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref pExistingTokenHandle); DuplicateToken(pExistingTokenHandle, SecurityImpersonation, ref pDuplicateTokenHandle) WindowsIdentity newId = new WindowsIdentity(pDuplicateTokenHandle); WindowsImpersonationContext impersonatedUser = newId.Impersonate(); FileStream stream = new FileStream("c:\\sectest\\Encrypted.txt", FileMode.Create, FileAccess.Write, FileShare.None, 512, FileOptions.Encrypted); BinaryWriter bw = new BinaryWriter(stream); bw.Write(this.textBoxText.Text); bw.Close(); impersonatedUser .Undo(); With FileOptions.Encrypted: If I impersonate the current windows logon (using LogonUser to get the handle) this works. I get an encrypted file. If I try to impersonate another user I get this exception message on the filestream constructor. "Access to the path 'c:\\sectest\\Encrypted.txt' is denied." With FileOptions.None: This works in both the above mentioned cases. I get this error regardless of whether the file exists or not. I have done the tests reversing two test accounts.

    - Unable to cast COM object of type 'System.__ComObject' This problem is driving me up the wall. I'm using .NET 2.0 and VS2005 to work with some of the Windows Media Format SDK through p/invoke I've created the appropriate interfaces I need and decorated them with ComImport, InterfaceType and Guid attributes. Specifically these interfaces are IWMReader and IWMReaderCallback I p/invoke the WMCreateReader method to instantiate and return an object implementing the IWMReader interface. The definition of this function is as follows: [DllImport("WMVCore.dll", EntryPoint = "WMCreateReader", SetLastError = true, CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] private static extern int WMCreateReader(IntPtr pUnkReserved, WMT_RIGHTS dwRights, [Out, MarshalAs(UnmanagedType.Interface)] out IWMReader ppReader); This gives me an object of type System.__ComObject when attempting to call the methods implemented by the IWMReader interface I receive the following exception: Unable to cast COM object of type 'System.__ComObject' to interface type '<interface name here>. This operation failed because the QueryInterface call on the COM component for the interface with IID '{96406BD6-2B2B-11D3-B36B-00C04F6108FF}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). The offending method is the Start method, although the Open method works perfectly. I have seen many posts regarding this problem but as of yet have not discovered a solution. The problem is not limited to the Windows Media Format SDK. The code works fine under .NET 1.1 & VS2003. I have attached the IWMReader interface definition for reference. [ComImport] [Guid("96406BD6-2B2B-11d3-B36B-00C04F6108FF")] [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IWMReader { void Open([In, MarshalAs(UnmanagedType.LPWStr)] string pwszURL, [In, MarshalAs(UnmanagedType.Interface)] IWMReaderCallback pCallback, [In] IntPtr pvContext); void Close(); void GetOutputCount([Out] out uint pcOutputs); void GetOutputProps([In] uint dwOutputNum, [Out, MarshalAs(UnmanagedType.Interface)] out IWMOutputMediaProps ppOutput); void SetOutputProps([In] uint dwOutputNum, [In, MarshalAs(UnmanagedType.Interface)] IWMOutputMediaProps pOutput); void GetOutputFormatCount([In] uint dwOutputNumber, [Out] out uint pcFormats); void GetOutputFormat([In] uint dwOutputNumber, [In] uint dwFormatNumber, [Out, MarshalAs(UnmanagedType.Interface)] out IWMOutputMediaProps ppProps); void Start([In] ulong cnsStart, [In] ulong cnsDuration, [In] Single fRate, [In] IntPtr pvContext); void Stop(); void Pause(); void Resume(); } Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109890

    - ConfigurationManager, user settings and application settings Hi, I'm looking for a way to save 2 lots of information from my C# application. I want to save information specific to the current user (such as colour settings, non-essential data) and information specific to the successful running of the application (such as server to connect to - but only the administrator can update). Can the ConfigurationManager class do this for me? If so, has anyone got any example code of using it? (The application settings should be saved in the same directory as the .exe in case the application is installed on a network).

    - Thread: Thread.Abort() and SmtpMail does not work thougether? I am making a windows-service in C#.NET 1.1 (that altso should be possible to run as an application for testing). The service shall do some work and sleep between each time the work is done (the sleep time is set in app.config). Using Thread.Sleep for pausing the application between each time the work is done. To be able to close the application/service anytime while in sleep its running in its own thread. Waiting with Abort() to Thread.ThreadState != ThreadState.Running. This works fine until I use SmtpMail.Send in the thread. If i do Thread.Abort() on the thread while it is sending a mail the application stops responding but does not close. The prosess must be aborted the hard way. Thread.Join() does not help. Any suggestion? Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109885

    - urgent!!! Problem opening solution file in Visual Studio Hi all, We are facing this big problem. Scenario is as follows. We have one single solution (say EIS) under which there are 25 projects. All the files are saved at a central location under Visual Sorce Safe on a seprate machine. For a new person who is trying to setup this solution file on his / her local machine follows the following step. 1. "Set working folder" for the EIS folder from VSS on to his local machine (by defualt D:\EIS) 2. Do a "get latest version" of all the files from VSS on to his local machine. 3. After all the files are copied on to local machine, EIS.solution file is opened in to Visual Studio environment by double clicking it. 4. For first time it ask for the server mapping for the projects under the solution file. On click of OK it creates virtual directory for EIS under IIS and further directories for projects under EIS (under IIS). Now problem is after it has added all the folders under IIS, visual studio hangs indefinately... and we are forced to do end task of the same. Again opeing EIS solution file, tries to create further directories under IIS and does not refer to the already created directories. We are not even able to locate the source the problem. Someone kindly help on this. Thanks & Regards Paras Sharma Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109881

    - Impossible? Who called the Method? Hi, How can I know inside a given method, by which method it was called? For instance: I have two property's (Prenom and Nom), both call the Method PropertyChangedHandler(). How Can I know if PropertyChangedHandle was called by the Prenom or by Nom? Public Event PrenomChanged As EventHandler Public Property Prenom() As String Get Return m_strPrenom End Get Set(ByVal Value As String) m_strPrenom = Value RaiseEvent PrenomChanged(Me, New EventArgs()) PropertyChangedHandler() End Set End Property Public Event NomChanged As EventHandler Public Property Nom() As String Get Return m_strNom End Get Set(ByVal Value As String) m_strNom = Value RaiseEvent NomChanged(Me, New EventArgs()) PropertyChangedHandler() End Set End Property Private Sub PropertyChangedHandler() 'I Want to know in this Method which property called it: Prenom or Nom... End Sub I could put the name of the property in a paramter like this: PropertyChangedHandler("Nom") etc. But in my opinion it's not really a nice solution :-) So is there any way to do it with a solution without everytime having to use a unique variable? something like the sender-object?

    - .NET 1.0 and/or 1.0 hotfix messing with 1.1 application? I've been trying to remotely assist a user who is encountering the infamous "Fatal Execution Engine Error (0x7927baca)" problem when invoking our .NET 1.1-based application. The system in question is running WinXP Home SP2. After sifting through as many documents as we could find, our first advice to the user was to remove our program, remove .NET Framework 1.1, and then re-install our program (our installer automatically checks for .NET and reinstalls .NET Framework 1.1 if needed). Well, our program ended up getting reinstalled, but .NET 1.1 apparently wasn't, perhaps because the user's system (unbeknownst to us at the time) also had .NET 1.0.3705 installed plus the 1.0 hotfix KB886906. Anyway, the situation now is that the user still has .NET Framework 1.0 and the KB886906 hotfix installed, and is somehow still hitting the same Fatal Execution Engine Error (0x7927baca) problem when running our program. Because the user is remote and not a computer expert, we want to make sure our next advice is productive. That's where we could use all of your expert advice. http://support.microsoft.com/kb/899619/ and a few other references suggest that you must remove KB886906 prior to installing the .NET Framework 1.1 ***Service Pack 1***, but can someone tell me if this restriction also applies to installation of .NET Framework 1.1 itself (i.e., the base package)? And can someone comment on whether the presence of .NET 1.0 and/or the KB886906 hotfix might cause the Fatal Execution Engine error described above? And lastly, is there a recommended procedure or sequence that we should adhere to, and/or things we definitely should NOT try, when trying to get this user back up using .NET 1.1?

    - Why so much trouble with ellipses? In a recent post of mine I mentioned the inaccurate shapes drawn by FillEllipse. In the response that I recieved I was told that DrawArc had less problems, which I found to be true (I have been using DrawEllipse, but they seem to have the same results when drawing a complete 360). However, even with these methods, there are situations where the results are not even symmetric along both axes (my best example of this is with a width and height of 6). I know enough about math and computers to be able to figure out how to write a simple method to create a basic circle or ellipse, so I'm not going to ask anyone to tell me how to fix it (even though that would be nice), but I am going to ask why couldn't Microsoft make this simple method themselves? It's not like this is the first time they ever had to do it. Heck, they could have just borrowed some code from Paint, I know that that makes correct circles/ellipses. Do they plan to fix this in a future version, or is GDI+ such a small part of .NET that they don't care? (I will admit that I am guilty of still using .NET 1.1, but I still think it should have been a simple enough task that they could have done it right by now).

    - Http web request error when trying to consume a webservice Hi, I had written an application in .Net 1.1 to consume a webservice. Recently we converted the project to .Net 2.0. After the conversion to .net 2.0 the application does not work anymore. The following error is returned when we make a Http Web request "The server committed a protocol violation. Section=ResponseStatusLine" Following the piece of code where it fails only in .net 2.0 but works in .net 1.1 ========================= HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(url); Request.Credentials = GetCredentials(url); //Send the request and wait for response. Response = (HttpWebResponse)Request.GetResponse(); --> Here it fails ========================= I think it is related to some unsafe header information. I also followed the following trick to ignore unsafe headers by adding the following in the config file. <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing="true" /> </settings> </system.net> Also if i try to add the web reference to the webservice in visual studio 2005 the following error By doing this it just worked once and stopped working.

    - Regular Expression Irregularity Okay, so I got really good at writing regular expressions using the Visual Studio find/replace dialog box, then I went to go use some of them in my code and discovered that they don't work. Reason? The RegEx class appears to support a completely different type of regular expression (one that still looks entirely like Greek even after reading the help). So, two questions: 1) Is there a class that supports the same type of regular expression used by the Visual Studio find/replace dialog? 2) If not, how would you write an expression equivalent to "walk~(ing)" (i.e., an expression that will find the word "walk" unless "ing" comes after it).

    - cannot install .net framework (any version) am having one hell of a time trying to install/uninstall (and vice versa) .net framework (any version 1.0, 1.1, 2.0) on a laptop running xpsp2. it all began when doing windows updates and the .net 1.1 sp1 failed. since then i've spent the last 8 hours trying to get it to work. i've followed a half dozen MS articles, most recently, the one that walks through manual uninstallation (kb article 320112). i'd thought i'd managed to remove all traces of all versions of .net. i tried to install v1.0 thinking that would be the easiest and that i'd simply update to later versions once the most basic was installed. i get the same problem, that is: the install seems to go through just fine until the very end where it hangs on "registering system.enterpriseservices.dll". it just stops here. any thoughts? how can i 'start from scratch', as it were. thanks, ross aseron Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109853

    - Instantiate Shell.Explorer.2 at runtime for a web page I want to create a custom user control to be used in a web page (by object tag) as an assembly. The user control needs to have a web browser control in it. Having tried with the managed System.Windows.Forms.WebBrowser or AxSHDocVw.AxWebBrowser, none of them worked from IE invocation unfortunately. While System.Windows.Forms.WebBrowser showed the page in Visual Studio 5000 Designer, AxSHDocVw.AxWebBrowser caught an exception at Navigate function call. Anyway, now I'm trying to use Shell.Explorer.2 in my custom user control at runtime. The way I instantiate it is such: Type loT = Type.GetTypeFromProgID("Shell.Explorer.2"); this.IE = Activator.CreateInstance(loT); Then, this.IE can access all the properties of the ActiveX control, like MenuBar, ToolBar etc. However, it failed at, again, calling Navigate method. Debugger won't step over the call. If I replace Shell.Explorer.2 with InternetExplorer.Application, it worked fine. Except that's not what I wanted because it launches IE in a separate window. Interestingly enough, if I embed Shell.Explorer.2 with its classid directly into my web html page. It showed well, except the html object id lost the reference to the control after exiting the onload function in my javascript. I must have missed something fundamantal in this attempt.

    - Invoking Windows Services Hi, Any help would be appreciated. I have come across an Architecture (not implemented) in my Enterprise, that has a Windows Service (A) written on VB COM that has to talk to another Windows Service (B) to be written on VB.Net. I can imagine one can easily write B in VB.Net, but my questions is - is it possible to invoke a Windows Service? A is supposed to pass an XML message to B and B is supposed to invoke an array of Components. To add to the woes, there is a .Net component called "B-Caller" with a CCW (Com calleable wrapper) that will invoked from A. Do you think this worthwhile? Sorry, for the length of the message but to summarize - 1. Is it possible to invoke methods or events from a windows service? 2. Do you think B-Caller is necessary? Please advice, if you could point me to a specific discussion board for this - would be great. Thank you, Sameer Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109830

Yes, of course events are not serializable and my proxy classes dont have those events (PropertyChanging and CancelEventHandler) but is it realy my problem or the Compact Framework not supporting System.ComponentModel.INotification interface? My compilation failed and it ask me to reference System.ComponenModel. So I edited the generated proxy class but still the project failed to compile. Hope you can help me. Thanks in advance!

    - Datagrid EnableViewState problem Hi everyone, I have a datagrid to display search results. The search results at this stage we only return the first 500 records to speed up the search. The problem is, if I turn the EnableViewState on, the search regularly failed with a message that says tempdb is full... It does not however happens all the time. I have tried to turn the EnableViewState off, that seems to do the trick but causes another problem, the datagrid's paging does not work for hidden pages (example, we only 5 pages, numbered 1, 2,.., 5 with the rest can be accessed by clicking the ... after the 5. After clicking the ... after the 5, the numbers 6 - 10 are displayed but if I click on any number from 7 to 10, it goes back to pages 1 - 5). HELP!!!! Is there a size limit to contents that can be displayed on an IE6 browser? Has anyone experienced the same problem or is it just me? Reducing the number of records returned is an alternative but it would be much better if someone has a work around. Any suggestion is greatly appreciated.

    - User profile space / Active directory integration Hi all, I have been given the task of (For each user in Active Directory) retrieving the following information from their Windows 2003 profile Number of and size of the following files each person has Audio Video Word doc Excel PowerPoint PDF Script (.js, .vbs) Miscellaneous I also have to query exchange and retrieve the number of emails they have as well as the amount of space they are taking up in exchange In order to do this I am currently going to their profile on the servers drive and running a recursive function which keeps track of all the information needed e.g. if it finds a word doc then it queries its size and adds it to the global WordDoc count and WordDocSize variables, same for all of the files mentioned above. When the recursive function exists it returns this information and the info is stored into the database. All the searching etc for all the files is done at the same time inside the same recursive routine. Now, as you could imagine, this takes a long time for the 4000 users in our AD.... I am using threading to speed it up by having more than one thread running at once doing the search (A thread is spun up for the first letter of each users last name so I have twenty six threads running at once, e.g. it searches for all lst names beginning wth A,B,C etc at the same time hence the 26 threads) and it seems to run fine. I am open to ideas about how I can speed up the search without having a million threads running at once Thanks in advance Mark Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109790

    - Problem - Serialization Is Losing Data My projetc has a simple DataDataSet (ds) that has a parentDataTable and a childDataTable table bound to 2 DataGridViews and its lossing data in serialization. The problem happens when: 1)A parent row and consequently its child row (cascade) are deleted from ds. 2)A new parent row and child row with the same values as deleted rows are created again. Notice that the problem only occurs if the new data are the same as deleted rows. Afterwards clicking on a button it is executed: 3) dsChanges=ds.GetChanges Stopping with debug you can see that there are 2 child rows in dsChanges.childDataTable, one with Deleted and other with Added RowState. 4) dsChanges.WriteXml("File.Xml", XmlWriteMode.DiffGram) dsChanges.Clear() dsChanges.ReadXml("Teste", XmlReadMode.DiffGram) Stopping with debug you will see that now there is only one child row with Deleted RowState. Where is the row with Added RowSate? Could someone explain me if I am doing a wrong understanding, or there is a actual problem with serialization? This is a problem to my system because in fact my program is not executing WriteXmL and ReadXml, actually it is sending the dsChanges to a another program though Remoting where it is executed serialization and the loss of data.

    - Prevent service from stopping Hi, I have a service which is only a server for some objects the user can instanciate and call. Right now, the service starts and then stops automaticaly. The only line of code I added is in the OnStart event and is "RemotingConfiguration.Configure(configfile)". So I guess the service is stopping because it has nothing better to do? Is there a setting I can set to prevent it from stopping? will I have to start a loop that will run until the OnStop event runs in order to keep the service alive?

After connection i want to send informational requests. If i send a request and the object is not connected yet i tell the Component to connect(sub RequestInfo). But before sending the request i have to wait until the connection succeded.

    - Problem with visual renderer Hi all I have a problem while using VisualStyleRenderer. I want to use a back buffer to draw a button using Visual Style. The problem is that the border of the button black (only 1 pixel of thickness). I investigate and I found that the border try to combine with the background to make a smooth effect. Now, if I use the Graphics returned by CreateGraphics, there is no problem of color (but some flicking effect, It is why I want a back buffer). Thanks, Laurent. This is part of my code that render the button with Visual Style. Graphics gr = CreateGraphics(); Image back = new Bitmap(hitZone.Bounds.Width, hitZone.Bounds.Height, gr); Graphics memgr = Graphics.FromImage(back); Rectangle rc = ...; memgr.SetClip(rc); ////// this line has no effect, whatever color is chosen memgr.FillRectangle(new SolidBrush(Color.White), rc); ////// I use a static member to store the renderer, so I do not create instance each time I have to redraw ////// I use Pressed and Hot state too VisualStyleRenderer StyleButtonNormal = new VisualStyleRenderer(VisualStyleElement.Button.PushButton.Normal); StyleButtonNormal.DrawBackground(gr, rc); gr.SetClip(hitZone.Bounds); gr.DrawImage(back, hitZone.Bounds); memgr.Dispose(); back.Dispose(); gr.Dispose(); Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109756

    - Weird error Hello, I encountered a very strange error in C#. I had a piece of code that extracts data from a hashtable. Here it is: public static ProcedureData GetProcedureData(string strProcedureID) { // Return procedure data from hashtable: return (ProcedureData)Configuration._proceduresData[strProcedureID.ToLower()]; } Pretty simple, isn't it? It worked fine most of the time, but in a particular case I found out it throws an exception (something like "object reference not found"). I started debugging this error, and got to this procedure. An important remark is that '_proceduresData' is loaded in the static constructor (therefore isn't null), and that the check for null input or output is done outside this function. So none of the reference objects were null. So I used the immediate window to evaluate the following statements: ?strTableID.ToLower() error: 'strTableID.ToLower' does not exist ?strTableID "dbsysuser" So, strTableID was a string but didn't support ToLower() function! How weird is that? I tried checking into it a little further, but at a certain point I split up the rows so the debugging will be easier. I came up with that new code: public static ProcedureData GetProcedureData(string strProcedureID) { string strProcedureIdLowerCase = strProcedureID.ToLower(); // Return procedure data from hashtable: return (ProcedureData)Configuration._proceduresData[strProcedureIdLowerCase]; } which works perfectly! So I no longer have any problem, I would just like to know if anybody could tell me why did it happen? What was the problem? Anybody ever encountered such an error? The code was written under Visual Studio .Net 2003, if that makes any difference. Thanks in advance, Yanir Tag: System.Threading.Timer vs System.Timers.Timer Tag: 109754

    - Outlook with VB.NET I am writing a class in VB.NET that will send an email. When the email is received in Outlook, that email needs to place an appointment on the Outlook calendar. Does Microsoft have Office 2003 controls that I can download for .NET? The class will run under a service that will have rights to the user's calendars therefore it should be able to just populate their calendars with appointments.

The System.Threading.Timer is lightweight timer where as the
System.Timers.Timer is server timer. The Timers.Timer can scale better
because they have built for it. My suggestion is if your application is
a server then you should probably use the System.Timers.Timer.

The MSDN article at the link below might help give you a better idea of what
each Timer is all about.
