    - performance - Comparison Hi! I have a simple doubt abt the performance when comparing variables with constats values.. Can any one tell me whether to use 1. int a; if(a==10) { MessageBox.Show("done"); } Or 2. int a; if(10==a) { MessageBox.Show("done"); } for comparing a variable.. which one will be wise to use if we are considering performance to be critical and why?? thanks, Baren Tag: abstract user control Tag: 109804

    - Aspnet_regiis I don't know if this is the right forum for me to post my question but I just hope somebody answers my question. Is there any way that I can retrieve the password of the aspnet account. I know that the password is machine generated but is there any method to retrieve the password? Can I change the password manually in the machine.config file? If so what can be the implications of this? One thing for sure is that I know manually changing the password will not synchronize the password with the IIS metabase but can aspnet_regiis with the i switch be used to do this synchronisation? Or for that matter does aspnet_regiis -i utility change the password for the aspnet account and synchronize it with the metabase? Too many questions!!!! but just hope somebody have answers for it...

    - using INotifyPropertyChanged interface in Compact Framework On my .Net 2.0 project: I implemented INotifyPropertyChanged on all my business entities to monitor property changes thru PropertyChanging event. It works fine on my web and windows applications consuming my buiness entities but these application do not consume the web service part. The problem occurs on the proxies generated when i referenced my web service and this ws uses these business entities. This is on a Pocket PC/CF2.0 application. 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: abstract user control 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?

    - 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: abstract user control 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: abstract user control Tag: 109754

    - "Error executing program!" when starting .Net 2.0 application Hi 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".

    - Index -1 does not have a value - DataGridView I was running into a problem with the DataGridView while binding it to an object Collection. I got it working and I thought others might like to know how. -------------- Problem ------------- The grid was bound to a simple object collection. The object contained string and decimal properties, nothing to fancy. When an item was added to the collection I would databind as follows (this happened on each item "Add"): myObject.CollectionProperty.Add(myBasicObject); dgvGrid.DataSource = myObject.CollectionProperty; bsBindingSource.DataSource = myObject.CollectionProperty; dgvGrid.DataSource = bsBindingSource; The reason I was binding twice was that the first bind didn't appear to allow the grid to hold more than one item. Now at run time if I added an object using the method above the grid would populate and it appeared to work fine. If I enabled deleting on the grid I could even delete the objects (using the grid and the delete button on my keyboard)... But wait! If I added an item after I deleted all the items in the grid (collection) and try to select it the grid would bomb out with the following error: "Index -1 does not have a value". -------------- Solution ----------------- After searching endlessly for some info I found that a few folks (thomas & Pieter) had run into this error but could not find any answer as to why. I decided to examine related objects (looking for cool property or a method that might save the day) and while doing so I came across the ResetBindings(bool) method of the BindingSource. I moved the binding information in the Add routine to a more appropriate location in the form initialization Then I simply added bsBindingSource.ResetBindings(false); to the Add routine, just after the object is added to the collection. Viola! Problem was fixed, and I no longer needed to bind the grid twice. I was able to make the binding work now with just this: bsBindingSource.DataSource = myObject.CollectionProperty; dgvGrid.DataSource = bsBindingSource; Any event that's probably just a problem I would have cause I'm just amateur, but who knows, maybe it might help someone.

    - String and StringBuilder ... ? I'm using VB.NET. I have been reading up for an exam I will be taking in a few hours, and I'm becoming confused... a String's contents never change? I read that every time I change a String it's actually giving me a reference to a totally different string; and that using a StringBuilder would be better if the String will be changing a lot. I really don't understand all this... I also don't understand really what the Stack and HashTable objects are good for, and I need to know this as well.

    - Should I try to upgrade to 2.0 over this problem? Just looking for some other opinions. I've Been working for some time on a problem with a web service running on framework 1.1. The problem occurs as a result of multiple calls to HttpWebRequest.GetResponse (or BeginGetResponse). Originally I was creating my own threads and calling GetResponse in each. After a huge amount of troubleshooting, I figured the problem must be with my created threads and I switched to calling BeginGetResponse multiple times so the runtime can create it's own threads. In each case the error is the same (a thread is unable to read from machine.config because the AppDomain is not loaded) and starts occurring when I try to make about 25 HTTP requests. Stack trace is at the top of this page: http://tinyurl.com/8f9lu This seems like an error in the ASP.NET engine. Is it worth the effort to upgrade the project to 2.0?

    - Forms Authentication stopped working for .htm/.doc extensions in 2.0!! Hello, I posted this under security and there were no replies. We have a website running ASP.Net 1.1 using forms authentication and even protects .htm/.doc files. We have associated such files to ASP.Net in Application Settings. Everything was working great until we moved to 2.0. If we try to access a .htm page we get "Page cannot be displayed errror". In the Application settings there are two check boxes "script engine" and "verify that file exists" both are checked by default. If the script engine check box is unchecked then it gives me "execute access is denied" error. Why is this breaking change from 1.1 to 2.0, how do we resolve it? Thanks. -- Jay Balapa www.atginc.com Tag: abstract user control Tag: 109677

    - Timeouts are not supported exception I am trying to xml serialize an object but when I pass in a memory stream I get an exception saying that "Timeouts are not supported by this stream." Why are timeouts required? This happens when I compile with VS2k5 .Net 2.0. It seems to work with .Net 2k3. public void Serialize(Stream stream) { XmlSerializer serializer = new XmlSerializer(typeof(MyObject)); XmlTextWriter writer = new XmlTextWriter(stream,System.Text.Encoding.GetEncoding(1252)); serializer.Serialize(writer,this); writer.Flush(); } Tag: abstract user control Tag: 109675

    - Late Binding Com : MissingMethodException Hi everybody, I have created a c# module using late-binding to call methods of a com component. Everything works fine in a console application but when I use this module in a web application I've got this exception : System.MissingMethodException: Method System.__ComObject.MyMethod not found. Here is my code : Type _UserComType = Type.GetTypeFromProgID("MyDll.MyClass"); object _UserCom = Activator.CreateInstance(_UserComType); object[] parameters = new object[2]; parameters[0] = "Data1"; parameters[1] = "Data2"; object result = _UserComType.InvokeMember("MyMethod", BindingFlags.InvokeMethod, null,_UserCom,parameters); Does anybody have a idea to solve this problem ?

    - Can't create WebRequest; NullReferenceException thrown All my Web-based .NET 1.1 applications stopped working as soon as I uninstalled the older versions and installed .Net 2.0 and Visual Studio 2005 this week. The apps use WebClient.DownloadFile() and WebClient.DownloadData(); in 2.0 those methods always throw WebExceptions that contain NullReferenceExceptions as their InnerExceptions. Since WebClient is said to be a thin wrapper around WebRequest/WebResponse, I wrote a test program to see if I could get around (or help define) the problem. A similar exception is thrown when I call WebRequest.Create(); the stack trace ends up in exactly the same place as it did with WebClient.DownloadFile(). For example: Uri RequestUri = new Uri("http://www.microsoft.com/"); WebRequest request = WebRequest.Create(RequestUri); results directly in a NullReferenceException with the following stack trace: at System.Net.WebRequest.get_PrefixList() at System.Net.WebRequest.Create(Uri requestUri, Boolean useUriBase) at System.Net.WebRequest.Create(Uri requestUri) What could be causing this? The URI and local filename are valid, there is no proxy server involved, Internet access on this machine is working just fine, and I'm logged on as an Administrator (yeah, I know I shouldn't be, but ...). My configuration wasn't changed except to remove all previous versions of the framework and Visual Studio before installing version 2.0 of the framework and Visual Studio 2005. Many thanks.

    - Heap and Garbage Collection Hi all, I was reading this article (http://msdn.microsoft.com/msdnmag/issues/1200/GCI2/default.aspx) in MSDN, written by Jerffrey Richter. He has explained the working of gabage collection pretty very well. What is confusing me here is when he talks about heap. He says that garbage collection must occur when heap fills. Is it different from saying Heap is full? I remember someon saying that garbage collection will occur when the heap is full. I only want to know whether the garbage collection occur only when the heap is full. Thanks pradeep_tp Tag: abstract user control Tag: 109663

Hi,

I am not sure if this is the right place for this question! Anyway,
here it is:

Is it possible to create a user control with abstract methods? I
couldn't do it. The reason is that I want to constrain the developer to
inherit from this abstract control!

Thanks in advance
Daniel

I see no problem and tested it in VS 2005. The abstract user control does
not show up in the list of user controls, but is still available in the
designer, so it seems exactly what you want. Are you working with an older
VS version?
