    - CSharpCodeProvider compiled my jpg files. cool! My team put this piece of code that used CSharpCodeProvider classes to do some dynamic c# scripting in our application. Everything was fine until the test team uploaded a jpg file instead of teh c# file...and the compiler compiled it without error. Does JPG files contain patterns inside that appear like code to teh compiler? The idea of compiling jpeg sounds intersting though.. anyone any idea? -Anupam CodeDomProvider codeProvider = null; codeProvider = new CSharpCodeProvider(); ICodeCompiler compiler = codeProvider.CreateCompiler(......); ........ CompilerParameters compilerParams = new CompilerParameters(); compilerParams.CompilerOptions = "/target:library /optimize"; <blah .... <blah... CompilerResults results = compiler.CompileAssemblyFromSource(compilerParams, Script); if (results.Errors.Count > 0) { foreach (CompilerError error in results.Errors) { //LogAllErrMsgs("Compile Error: " + error.ErrorText + "\r\n\r\n"); msg.Add("Compile Error: " + error.ErrorText); } result.Add("Message", msg); result.Add("SuccessFlag", 0); return result; } else { msg.Add("Script compiled successfully without any errors"); result.Add("Message", msg); result.Add("SuccessFlag", 1); return result; } Tag: Error window web access failed is displayed Tag: 120947

    - Browser window maximizing from code/script ?? Hi, The vertical scrollbars on a frameset page kinda get lost periodically. necessitating maxing the browser window every so often. Some of the pages in the framesets I do resize using Jscript's window.resizeto(,); Is there anyway of ensuring these or the main frameset page, maximize everytime? If so, ..How?

    - Serialization help needed I'm writing kind of a "network monitor" application in .NET 2.0 (C#); At runtime, the user should be able to configure all kinds of different "sensors" and I want to serialize them to an xml file. There are several different classes for different sensors, all derived from an abstract base sensor class: public class Sensor { public SensorResult Sense(); } public class PingSensor: Sensor { string Hostname; int timeout; ... } public class PortSensor: Sensor { string Hostname; int Port; ... } ... Ideally, the resulting xml file would like this (for example): <sensor type="Sensaction.PingSensor, sensaction.core" name="Ping some server" host="SomeServer" timeout="5000"/> <sensor type="Sensaction.PortSensor, sensaction.core" name="Sql port on db server" host="dbserver" port="1433"/> <sensor type="Sensaction.HttpSensor, sensaction.core" name="Homepage availability" url="http://www.somedomain.com/index.htm"/> I've seen the "Namespace.Class, Assembly" notation in several .config files and like them pretty much (because some advanced users might want to create these xml files by hand). My questions are: 1. Is serialization the way to go, or am I better off with System.Configuration.* ? 2. If it is serialization, how do I start? (I must admit I never did this before) Any help would be greatly appreciated! Jens Tag: Error window web access failed is displayed Tag: 120944

    - Optimising data retrieval display ie negating Postbacks.. ?? Hi Scenario,.. I have several LBoxes on an ASPX page, each of which's data is dependant on the selection made of the preceding one, eg States, Regions and Cities,... Select a state and server code executes on Postback to retrieve Db data of regions within the state, and on region selection, to rerieve towns/cities within that. It runs within a frameset currently, but the continual page refresh and time are things I would like to avoid. Any links or suggestions ... i guess it will have to do with script (not my strong point yet). thanks Neal -- Neal Rogers University of Cape Town Tag: Error window web access failed is displayed Tag: 120939

    - FTP rename fails with unix servers dotnet 2.0 I'm writing an app to upload/download via FTP using VS2005. I am using the FTP Client Library for .NET 2.0 by Howard Richards: http://www.codeproject.com/vb/net/FtpClient.asp Upload download works. but when trying to rename a file with GetResponse it errors with error 500 (Syntax error, command unrecognized). This only happens with unix FTP servers - windows ones work perfectly. I am trying to rename the files before downloading, to avoid contention - attempting to dowload a file before it has finished being uploaded. (if someone could suggest another way to avoid this contention, I wouldn't need the rename command). I have seen someone else with hte exact same problem, but it hasn' been resolved: http://groups.google.co.uk/group/microsoft.public.dotnet.general/browse_thread/thread/17a43b1cae83129c/456d4f335f0ba60c?lnk=gst&q=ftp+issue&rnum=1#456d4f335f0ba60c for the time being I am going to use a third party tool, but I'd rather have the source of any code I use ... -- Marty Tag: Error window web access failed is displayed Tag: 120938

    - File.Exists? A file named Form1.asp exists in the folder C:\Inetpub. The following code exists in a file named FindFile.aspx which exists in C:\Inetpub\wwwroot\ASPX: <script runat="server"> Sub Page_Load(obj As Object, ea As EventArgs) Dim ioFileInfo As FileInfo ioFileInfo = New FileInfo(Server.MapPath("../../Form1.asp")) If (ioFileInfo.Exists) Then Response.Write("File Exists") Else Response.Write("File Doesnot Exist") End If End Sub </script> Now since FindFile.aspx exists in the folder C:\Inetpub\wwwroot\ASPX & the file I am searching for (Form1.asp) exists in C:\Inetpub, I have to move up by 2 folders which is why I have used ../ twice in Server.MapPath but ASP.NET generates the following error: Cannot use a leading .. to exit above the top directory. pointing to the Server.MapPath line.

    - simple Socket Programming question. Hi, I am a bit new in socket programming and I have a question about what's the best way to implemnt a TCPClient that can receive long messages? The example I found in MSDN works for me but it downloads only the first chunck of data sent by the server I connect to. How can i make the code wait until the end of the message is received from the server? Changing the buffer size won't change anything as i guess the stream.Read() method returns after the first bunch of data is received from the server. I don't really know how many packets is that neither why it returns before everything is read but i guess that i need to add in some infrastructure that will do some waiting and / or looping and which will detect when all the data is read and that i can exit. I have done some research on the internet and the example i saw often did not care for this kind of longer message or were too complex or not working if not communicating with their own server implementation. I have no access on the server I connect to then I cannot change anything on that side. Here is the code i use from MSDN doc (TCPClient class): static void Connect(String server, String message) { try { // Create a TcpClient. // Note, for this client to work you need to have a TcpServer // connected to the same address as specified by the server, port // combination. Int32 port = 13000; TcpClient client = new TcpClient(server, port); // Translate the passed message into ASCII and store it as a Byte array. Byte[] data = System.Text.Encoding.ASCII.GetBytes(message); // Get a client stream for reading and writing. // Stream stream = client.GetStream(); NetworkStream stream = client.GetStream(); // Send the message to the connected TcpServer. stream.Write(data, 0, data.Length); Console.WriteLine("Sent: {0}", message); // Receive the TcpServer.response. // Buffer to store the response bytes. data = new Byte[256]; // String to store the response ASCII representation. String responseData = String.Empty; // Read the first batch of the TcpServer response bytes. Int32 bytes = stream.Read(data, 0, data.Length); responseData = System.Text.Encoding.ASCII.GetString(data, 0, bytes); Console.WriteLine("Received: {0}", responseData); // Close everything. stream.Close(); client.Close(); } catch (ArgumentNullException e) { Console.WriteLine("ArgumentNullException: {0}", e); } catch (SocketException e) { Console.WriteLine("SocketException: {0}", e); } Console.WriteLine("\n Press Enter to continue..."); Console.Read(); } Anyone can help me or point me to an adequate resource?Thanks a lot,Francois Malgreve Tag: Error window web access failed is displayed Tag: 120936

    - Crystal Report Viewer Memory Overhead I am developing a windows application in VB.NET 2005 that includes a number of crystal reports. To use the reports I use the included crystal report viewer and pass a dataset to the report at runtime in order to report from. The issue I am having is with the amount of memory that the crystal viewer uses and doesn't recover. When I first load a report it can add an extra 30Mb to my applications memory usage, then as I close and open report viewer that usage keeps increasing. The memory overhead never seems to recover after I have closed the crystal viewer. I have been looking at VB.NET 2005 and using the new crystal viewer in that environment has the same problem, if not actually using more memory to display the same report. Is this a known issue, and if so are there any known solutions? Any advice would be appreciated. Tag: Error window web access failed is displayed Tag: 120935

    - DataControlFieldCollection instantiated twice I'm trying to create my own GridView with some addons. I'm realising that by creating a placeholder with a GridView and SQLDataSource in it. The problem is dat the fields defined in the DataFieldControlCollection gets instantiated twice with which the second instantiation doesn't have any attribute/property set. Here is my code: <phaFramework:EditGrid id = "E01" query = "SELECT bla FROM bla" runat = "Server" > <Fields> <phaForm:frwNumericField ID = "percentage" HeaderText = "Percentage"> <validators> <phaValidator:frwNumericValidator minimalValue = 0 maximumValue = 10 /> </validators> </phaForm:frwNumericField> </Fields> </phaFramework:EditGrid> Public Class EditGrid Inherits PlaceHolder Friend WithEvents baseGridView As New GridView Friend WithEvents baseDataSource As New SqlDataSource Public Sub New() Me.Controls.Add(Me.baseGridView) Me.Controls.Add(Me.baseDataSource) End Sub Public ReadOnly Property Fields() As FormFieldCollection Get If ViewState("Fields") Is Nothing Then ViewState("Fields") = New FormFieldCollection(Me) End If Return ViewState("Fields") End Get End Property End Class Public Class FormFieldCollection Inherits List(Of iFormField) End Class Public Class frwTextField Inherits TemplateField Implements iFormField, IBindableTemplate Protected arrValidators As New ValidatorCollection Public ReadOnly Property validators() As ValidatorCollection Get Return Me.arrValidators End Get End Property End Class Public Class ValidatorCollection Inherits List(Of BaseValidator) End Class Basicly that's it. I have ofcourse simplified the code. It is mush more than this. I've put logging (Trace) everythere and there i can see that the frwNumericValidator is created and added to the List of validators. When the Template of the field is instantiated (InstantiateIn called) the validators collection is empty (count=0). I can also see that the ValidatorCollection is created twice (the New contstructor called twice). what i think is that: 1) the FieldCollection is created by me with the New constructor 2) the FieldCollection is also created by restoring the ViewState. And that in between the properties are set so that the second instantiation doesn't have these properties set (these properties are min/maxValues as can be seen as attributes of the aspx tag). I've tried several options. I've tried creating the FieldCollection as a StateManagedCollection (like the GridView.columns). No success. Can someone explain me how the .Net framework works? What is it doing? Sam. Tag: Error window web access failed is displayed Tag: 120921

    - FYI: Xmpp (Jabber) c# codebase, BSD style license, Piorun.Xmpp For general information... as I spent a lot of time tracking down the library I liked and wanted to be sure it was getting the attention it deserved. I am a long-term users of Jabber-net for our xmpp library but were growing frustrated with the lack of Compact Framework support. I found the jabber-net codebase too difficult to work with, just a clash in programming style... so I went looking for alternatives. I recently discovered a library named Piorun.Xmpp with a very clean codebase and a flexible license (MIT X11, similar to BSD license). It was available in the experimental .NET programming language Boo but we recently completed a C# conversion and now both languages are available for Piorun.Xmpp. The code is available here: http://piorun.sztorm.net/trac/ Based on my own experience, I would consider Piorun.Xmpp a good alternative to AgsXMPP (good cross-framework support, but restrictive license) and Jabber-net libraries (good license, but no support of Compact Framework). There is a mailing list for developers if you want to help contribute. I will be subscribed if you need any assistance with the library. Now that we have a C# version working, I am still doing some work on the Compact Framework 1.x compatibility, but it is only minor changes. Hope this is of use to someone.

    - Async Sockets and IOCPS Hang my head in shame; I only found out yesterday that .NET sockets are already doing overlapped I/O with IOCPs when you make async calls. The only problem I see (experimentally via debugging, so I don't know if it's true), is that each socket gets it's own IOCP. Is there any way to attach a socket to a specific IOCP, the way you do in Win32? Thanks, -- kov Tag: Error window web access failed is displayed Tag: 120909

    - Deploying native Windows DLL used by .NET applications We have a native Windows DLL (let's call it native.dll) we developed a .NET interface for (let's say managed.dll). When a .NET application now uses the .NET interface to talk to the Windows DLL we always thought that managed.dll must be copied to the application directory (where the .NET application runs) and that native.dll can be anywhere as long it is in PATH or is somehow else found by Windows. The problem is however that the .NET application hangs on some computers unless native.dll is copied to the application directory. The problem is reproducable but exists only on some computers. On one computer native.dll can be copied to the Windows directory and everything works fine. On the other computer native.dll must be in the applicaton directory as otherwise the .NET application hangs when it tries to access native.dll. I used Dependency Walker (from http://www.dependencywalker.com/) to make sure that in every scenario all DLLs can be found. Thus I wonder why on some computer native.dll must be copied to the application directory for the .NET application not to hang. Is there a deployment recommendation like this? Or is this a bug in the .NET framework or CLR which doesn't locate DLLs correctly sometimes? Boris Tag: Error window web access failed is displayed Tag: 120895

    - creating dynamic Excel forms, w/ validation -- possible? hello, i am on an interesting project. in this project, i have to create dynamic data-entry forms for offline-users to fill out, save locally, and eventually postback to our app (when back online). data validation is required on the form. i had looked at using PDF-forms for this.. Adobe's "LifeCyle Forms" would work perfectly. with it one can pass in xml to their webservice & get back PDF-form binaries. however, Adobe's pricing is simply unrealistic for any but super-large budgets (got an extra 50k + 20% annual maintainence for your project? talk to adobe). so now im back to something low-tech. sure, i could do it w/ .HTML forms w/ javascript validation, and use javascript to save the data-entry into a .xml file. however, a two-file solution is not viable for us. my next idea is probably better from a user standpoint anyway -- Excel forms. the user could input into the excel doc, save it, and later return it to us. two key questions: 1) can i build dynamic Excel forms w/ .NET? 2) if so, can i build them w/ any kind of data validation? any help would be greatly appreciated! thanks, matt Tag: Error window web access failed is displayed Tag: 120892

    - Immutable Classes I've got some classes that I've built that currently require far too many locks when they're running in a multi-threaded environment. To get around this, I'm looking to make these classes immutable. I'm also trying to be (as any good programmer) as lazy as possible about the approach tha tI take. I have a class (XmppId) that has roughly the same properties on it you would expect of an email address. I would like to be able to say, "public class ImmutableXmppID : Immutable<XmppId>{}" I would also like to take the same approach as strings, with a global Intern list and precalculated hashes in order to help with performance. The issue so far is that this seems to be well beyond the scope of what Generics can do. The only option for doing this that I can see is to build a CodeSmith template, or even a custom piece of Code Generation for the CodeDOM, and then do it.

DataView dv = myDataRowView.CreateChildView("myRelation"); is slower than... DataRow[] drs = myDataRowView.DataView.Table.DataSet.Table[0].Select(string.format("ID = '{0}'"), myDataRowView["ID"}); with 3000 rows in Table[0], i have a piece of code that takes 10-11 secs to run using CreateChildView() vs .05 secs using Select(). i would just use the Select() method, but i lose the ability to use BoundFields in a GridView (and also Eval in the TemplateFields. i have to cast the DataItem each time i want to access a field in the DataRow) any advise would be greatly appreciated. thanks, bk Tag: Error window web access failed is displayed Tag: 120885

    - Asynchronous Design Pattern I'm thinking about using the design pattern described at the link below to solve a problem: http://msdn2.microsoft.com/en-us/library/ms228963.aspx I have a question, though, and would appreciate any help. The pattern describes using BeginOperationName and EndOperationName methods for asynchronous operations, where "OperationName" represents the name of the operation to be invoked asynchronously. For example, say you want to read from a Stream asynchronously. You would call BeginRead, passing it an AsyncCallback delegate and possibly an object representing state information. At some point, the stream invokes your callback. In your callback, you call EndRead, passing it the IAsyncResult object given to you to get the result of the read operation. Ok, say we are writing a class to implement this pattern. Instread of reading bytes, we're reading an object of some type. Let's call the class ObjectReader. We have the methods BeginReadObject and EndReadObject. Like the Stream class, this class has a Close method that disposes of the object. Where it gets fuzzy for me is trying to figure out what should happen when the BeginReadObject method is called and the ObjectReader's Close method is called before the specified callback is invoked. My thought is that in response to being closed, the ObjectReader should invoke any awaiting callbacks. When the callback calls EndObjectRead, it returns null indicating that no more objects are available to be read. Once all awaiting callbacks have been invoked, the ObjectReader finishes closing down. At this point, it is officially closed; any attempt to read from the ObjectReader will throw an ObjectDisposedException. For BeginReadObject operations that were invoked without a callback, i.e. null was passed instead of a delegate for the callback parameter, the wait handles of any remaining IAsyncResult objects are set when the ObjectReader is closed. Calls to EndReadObject behave just as they would inside the callback. Any thoughts? Tag: Error window web access failed is displayed Tag: 120880

[TextBoxBase.cs] namespace CuiNetCF.Windows.Forms { public partial class TextBoxBase : System.Windows.Forms.TextBox { public TextBoxBase() { //Maintained by the designer InitializeComponent(); } } } [TextBoxInherited.cs] namespace CuiNetCF.Windows.Forms { public partial class TextBoxInherited : TextBoxBase { public TextBoxInherited() { //Maintained by the designer InitializeComponent(); } } } Here are the steps that I do to create this problem: 1.) Create a new windows project. 2.) Add a new Custom Control called TextBoxBase.cs. 3.) Change the TextBoxBase class to inherit from TextBox. 4.) Add a new Custom Control called TextBoxInherited.cs. 5.) Change the TextBoxInherited class to inherfit from TextBoxBase. 6.) Try to view the TextBoxInherited class in the designer. Does this error out for anybody else??? Tag: Error window web access failed is displayed Tag: 120871

    - .NET 2.0 embaressment Hi everyone. I have a .NET 2.0 application that has been released using clickonce installation both online and from CD. I have no control over the end user systems and I am being flooded with complaints that the application fails to install on XP SP1 machines and NT4 systems. I understand that these two operating systems are not on the .NET framework 2.0 compatbility list. However the application will install and run on XP SP1 if I remove the MDAC 2.8 dependancy. However removing the MDAC 2.8 dependency means that windows 98 and ME systems will fail if MDAC has not been installed. The application was been very well received but the installation issues have left me red faced. I would like to redistribute the application but this time I do not want the installation to fail if the OS is not supported. I am OK about not supporting NT4, but I would like conditional support for XP SP1 installs using MDAC 2.7. Steve Tag: Error window web access failed is displayed Tag: 120864

    - Click once and exe.config file I'm about to release a application to a customer. This app uses a config file to store connection settings. I'd like to be able to create a "Click Once" installer, as this will remove lots of dependency issues that are likely to arise with this app. However, my understanding of click once is that the application is installed to a obscure location, thus making it difficult for the customer to locate the config file in order to edit the settings. Is there an easy way around this, or given the requirements, would I be best advised to create a traditional installer package? I'd be grateful for any comments, as its vital I get this working correctly! Greg. Tag: Error window web access failed is displayed Tag: 120861

    - Adding a Section In Configuration File I know that we can add a single name value entry in app.config or web.config in the configuration/configSettings/appSettings section like so: <add key="key" value="value" /> Question: I want to add a dictionary of name-value pairs. In other words, instead of a single name-value, I want to add a name-value collection in there. I could do this: <add key="key1" value="value1" /> <add key="key2" value="value2" /> <add key="key3" value="value3" /> but that would mix it up with other members that I do not intend to have as a part of this collection. Is there a way I can add a collection itself? How? And how would I then access it? Tag: Error window web access failed is displayed Tag: 120860

    - Converting 1.1 webapp to v2 Hi, We've finally got around to getting VS2005 for our development team and will be slowly, but surely upgrading all our in house projects accross. However -we have fallen at the first project! when converting a V1.1 web app to V2 - when compiling we get the following error: Error 1 The type 'ProductDB.Global' is ambiguous: it could come from assembly 'C:\Source\Systems\ProductDBAdmin\ProductDBAdmin_Mainline\src\AdminGui\bin\DRL.ProductDB.DLL' or from assembly 'C:\Temp\admingui\5f2af3cc\f03cc022\App_Code.jgiqizcm.DLL'. Please specify the assembly explicitly in the type name. C:\Source\Systems\ProductDBAdmin\ProductDBAdmin_Mainline\src\AdminGui\Global.asax 1 I have searched the web and the only replies I can see are "Delete your bin folder contents" or "Delete the temporary files folder" none of which worked for me.. Is there a fix / workaround / article for this that I'm missing? Regards Phil Yardley Tag: Error window web access failed is displayed Tag: 120859

    - User interface editor I am able to add different dialogs to my deployment project using the User Interface Editor in Visual Studio .NET 2003 but I am yet to find out how to retrieve the values entered by the user during installation. For example, if I add a new dialog which contains a TextBox and I ask the user to enter their name, how do I retrieve that name? I have scanned the web for a long time and yet I still haven't seen an example of how to get the values entered by the user during installation. Can anyone please point me to a suitable demonstration? Tag: Error window web access failed is displayed Tag: 120858

    - AppSettings trough ConfigurationManager I have a small test app with the code: Configuration cf = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); cf.AppSettings.Settings.Add("EnNyNokkel", "EnNyVerdi"); cf.Save(); If i run my app from inside VisualStudio through debug my created config file is created on startup of the program, but deleted when main is finished! If i however run the app from commandline or explorer, the configuration file is not deleted when the application finishes. Any good ideas why? Is this default debug settings?

    - show big image Hi all I have this problem I'm developing an application c# that interfaces with a digital camera as soon as the image is shot I download it in the PC and show it The problem is this one: the image is very big : 16 megapix! when I load it in a picturebox. If i try to pan or zoom (i modified the picture box to do that) the app is stuck ( I suppose because the load of panning and resizing such a big picture is very big too). I noticed that the same image is managed in a very efficient way by some freeware application such as for example irfan view My question is: there is a way in c# (maybe by a freeware library or component) to show, pan and zoom such a big image?

    - The security alert dialog does not appear when my program sends UD I would like the user to be able to choose "Unblock" on the security alert dialog when my application attempts to send a UDP packet for the first time. However, the securlty alert dialog does not appear. I have to tell the user (when running the app for the first time) to manually add my app to the exceptions list in the firewall. Why isn't windows prompting the user with the security alert dialog? I have the "Display notification..." check box checked, and it still doesn't appear. Is there something I should do before sending the packet? Doesn't the security alert work with UDP packets? Thanks Tag: Error window web access failed is displayed Tag: 120841

    - Saving a locally created Bitmap Seems like this ought to be an easy one. Essentially, using managed C++, I'd like to be able to create a Bitmap locally, set the pixels to particular colors, and save the result. Everything seems to work fine except that upon calling the Bitmap's Save function I always get a status of "FileNotFound" and it creates a file with 0 size. The Code: void CChildView::Test() { Gdiplus::Status stat; Bitmap bmp(2048,2048,PixelFormat24bppRGB); Color red,grn; red.SetFromCOLORREF(RGB(255,0,0)); grn.SetFromCOLORREF(RGB(0,255,0)); int i,j; for(i=0;i<2048;++i) { for(j=0;j<2048;++j) { if(i==j) stat=bmp.SetPixel(i,j,grn); else stat=bmp.SetPixel(i,j,red); } } CString sPath("c:\\test.png"); WCHAR wszPath[256]; MultiByteToWideChar( CP_ACP, 0, sPath, sPath.GetLength()+1, wszPath, sizeof(wszPath)/sizeof(wszPath[0]) ); stat=bmp.Save(wszPath,&ImageFormatPNG); } I should mention that yes, Gdiplus is initialized prior to entering this function. Status (stat) remains "OK" until the Save operation, where it changes to "FileNotFound". What am I missing here? I've had the same problem with different file types (BMP rather than PNG, for instance). Tag: Error window web access failed is displayed Tag: 120839

    - ILASM for Compact Framework 2 I already asked in CF group, but nobody was able to help me - I hope someone here would know the answer... I need to compile some IL code to CF2 class library (.dll). I just tried it, got the dll using something like "c:\WINNT\Microsoft.NET\Framework\v2.0.50727\ilasm.exe /DLL mycode.il". The DLL looks ok on first sight (I can see all the classes using reflector), but if I add the assembly to my SmartDevice CF2 project in VS2k5, I'm not able to use the classes. The reference is added without any error messages, but the compiler doesn't recognize names of the classes in the assembly if I try to use them... If I try to use the assembly from WinForms project, everything works ok. So it looks like the ilasm generates just full-framework compatible assembly. Is there any special ilasm.exe tool for compact framework? Tag: Error window web access failed is displayed Tag: 120830

In local system .net is working fine, but while working on LAN we are
facing a problem .
We open IDE and select new project for with Visual basic template
choose asp.net webapplication

Then we give path as http://serverip/nameofapplication on clicking ok
button
The error window web access failed is displayed .

Which says "unable to create web project "webapplication1".The
UNC share \\server\wwwroot$\webapplication1" does not exist or you do
not have acess.

If we try removing "$" sign from wwwroot then error changes to HTTP
Error 404 :Not Found but file have have permission for client acess.

This is the problem we are facing while trying to access .net in
network.

Since we are not able to configure this Client Server application we
are not able to takeup development.Kindly help us and provide the
solution for the same.

Thank you,

Hi

Has the web already been generated on the IIS as a virtual web application
and do you have enough permission to access it?
Has the virtual web application configured to access you startup document
(like ist .aspx allowed. what ist the startpage etc)?
