  • Syncronizing multiple exchange servers 2007

    - by Mustafa Ismail Mustafa
    We're introducing a new exchange server for several reasons. After the introduction of the new server, and synchronizing it with the old one (mailboxes, contacts, rules, the whole shebang) we're going to be formatting the old machine, install XenServer 5.5 on it, and create a slices, one of which will have Exchange server, which again will need to be synchronized. Then, we'll have 2 different routes to the mail servers (mx1, mx2) so that if there is an outage on one, the other should be available. So now, I'm wondering how to synch? I can move a mailbox from one server to the other, and I'm sure that can be done in bulk, but that's not what I'm looking for. I'm looking to make both Servers equal, the first time so I can make a backup of the original, and the second time so that they can be made into peers. This is with Exchange 2007 on Windows 2008 R2 (x64) Suggestions? TIA

  • Moving MS Exchange 2007 to another machine

    - by Mustafa Ismail Mustafa
    We have a machine that has been chugging along with the burden of both Exchange and DC and DNS all with SBS 2008. We have a better machine now and I'd like to move Exchange 2007 to that machine and take it off of this machine. In fact, I'm planning on formatting the old machine and get rid of SBS all together because it is making the machine SLOW. How would I go about making the move? I've read on previous versions of Exchange (2000), that all you do is install Exchange on the new machine and then start moving mailboxes one after the other. Well, what about all the different rules we have in place? How do those get moved? How do we de-commission the old exchange and set up the new exchange as the primary one? Come to think of it, how do we have both exchanges recognize each other on the same domain? TIA

  • Active Directory + IIS + SQL + ASP.NET

    - by Amira Elsayed Ismail
    I have sent the following question to stackoverflow website I have installed Windows server 2008 r2 on a virtual machine, Can I install Active directory with domain controller + IIS + SQL server on the same machine? I want to make web application and this web application will authenticate users from Active Directory, the web application should be published on the server IIS and the users should access it remotely from their home using domain name of my machine, Someone tell me that its very wrong to have IIS and Active directory on the same machine I got the following Answer You can't use ActiveDirectory over the internet. At least not without something like a VPN as a middle man. Their home computers will not be joined to the domain, so there is no pass-through authentication. Yes, it's a bad idea to put AD on the web server. Why is too complex to get into in an answer here. Suffice it to say that even if you did do this, it's probably would not work the way you are thinking it should. It's not impossible to do this. For instance, many of the Microsoft "Small Businesss" products put IIS, AD, and SQL Server on the same server. But, you kind of have to know what you're doing to configure it securely. Then I add the following comment Thanks for ur reply.so what you think about the best way to do this as I didn't do anything like that before should I install active directory on a machine and IIS on another machine ? and what about SQL should I add it to the same server of active directory ? I didn't mentioned also that it will be Microsoft dynamics server that will access some information about work and i have to read data from axapta also ? also what is VPN and how can I use it to let users access my web application anywhere ? Sorry for my long questions and thanks in advance so please if anyone can help I will be thankful

  • "pull" process/job into the background

    - by Mustafa Ismail Mustafa
    I know of terminating a command with & and then moving it into the background by pressing Ctrl-Z and then bg [pid], and I also know of nohup. But say you started a process that turned out to take much longer than one expected, is there a way of pulling, so to speak, this process from another terminal screen into the background so that even if I log off from the server the process would continue?

  • Catches communication exception instead of custom fault exception - WCF

    - by Ismail S
    On Server I'm throwing the exception like this. catch(SqlException exception) { if (exception.Message.Contains("Custom error from stored proc")) { //Exception to be thrown when authentication fails. throw new FaultException<MyServiceFault>(new MyServiceFault { MessageText = exception.Message }); } } And on client end I'm catching the exception catch(FaultException<MyServiceFault> faultException) { } Here is my MyServiceFault [DataContract] public class MyServiceFault { [DataMember] public string MessageText { get; set; } [DataMember] public Guid Id { get; set; } } The problem is that on client, it doesn't go to MyServiceFault catch block instead it goes to communication exception catch block and throws this error System.ServiceModel.CommunicationException: The underlying connection was closed: The connection was closed unexpectedly. ---> System.Net.WebException I've also decorated my service method [FaultContract(typeof(MyServiceFault))] in the interface which is implemented by my service. In my web.config servicebehaviour tag consist <serviceDebug includeExceptionDetailInFaults="true" /> Any idea where I'm going wrong

  • Where is ScriptManager.IsStartupScriptRegistered method?

    - by Ismail S
    Below is my code if (!Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey)) { ScriptManager scriptManager = ScriptManager.GetCurrent(page); if (scriptManager != null && scriptManager.IsInAsyncPostBack) { //if a MS AJAX request, use the Scriptmanager class ScriptManager.RegisterStartupScript(Page, Page.GetType(), scriptKey, script, true); } else { //if a standard postback, use the standard ClientScript method Page.ClientScript.RegisterStartupScript(Page.GetType(), scriptKey, script, true); } } I'm doing as suggested in this answer so that I can register startup script on both times i.e. when there is partial postback and a full postback. The problem is Page.ClientScript.IsStartupScriptRegistered(Page.GetType(), scriptKey) always returns false when it is partial postback. And I couldn't find ScriptManager.IsStartupScriptRegistered method. As a result of this additional script is emitted on all partial/async postbacks. Please note that I'm using script manager of AjaxControlToolkit version 4.1 i.e. ToolkitScriptManager in my masterpage. But I don't thing it has something to do with this. UPDATE <asp:UpdatePanel ID="ContactDetailsUpdatePanel" UpdateMode="Conditional" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="UpdateContactDetailsButton" EventName="Click" /> </Triggers> <ContentTemplate> <div id="ContactDetailsContent" class="contact_details_content"> <div class="customer_contactdetails_left_pane"> <div class="customer_name_field"> <asp:Label ID="CustomerNameLabel" runat="server" Text="Customer" /> <asp:TextBox ID="CustomerNameValue" runat="server" /> </div> <div class="customer_address_field"> <asp:Label ID="CustomerAddressLabel" runat="server" Text="Address" /> <asp:TextBox ID="CustomerAddressValue" runat="server" /> <asp:TextBox ID="CustomerAddressValue1" runat="server" /> <asp:TextBox ID="CustomerAddressValue2" runat="server" /> <asp:TextBox ID="CustomerAddressValue3" runat="server" /> </div> <div class="customer_postcode_field"> <asp:Label ID="CustomerPostcodeLabel" runat="server" Text="Postcode" /> <asp:TextBox ID="CustomerPostcodeValue" runat="server" /> </div> </div> <div class="customer_contactdetails_right_pane"> <div> <asp:Label ID="CustomerContactLabel" runat="server" Text="Contact" /> <asp:TextBox ID="CustomerContactValue" runat="server" /> </div> <div> <asp:Label ID="CustomerTelephoneLabel" runat="server" Text="Telephone" /> <asp:TextBox ID="CustomerTelephoneValue" runat="server" /> </div> <div> <asp:Label ID="CustomerMobileLabel" runat="server" Text="Mobile" /> <asp:TextBox ID="CustomerMobileValue" runat="server" /> </div> <div> <asp:Label ID="CustomerFaxLabel" runat="server" Text="Fax" /> <asp:TextBox ID="CustomerFaxValue" runat="server" /> </div> <div> <asp:Label ID="CustomerEmailLabel" runat="server" Text="Email" /> <asp:TextBox ID="CustomerEmailValue" runat="server" /> </div> <div> <asp:Label ID="CustomerWebLabel" runat="server" Text="Web" /> <asp:TextBox ID="CustomerWebValue" runat="server" /> </div> </div> </div> <div class="update_button_field"> <asp:Button ID="UpdateContactDetailsButton" runat="server" Text="Update" onclick="UpdateContactDetailsButton_Click" /> </div> </ContentTemplate> </asp:UpdatePanel> Thanks in advance.

  • ASP.Net MVC Exception Logging combined with Error Handling

    - by Saajid Ismail
    Hi. I am looking for a simple solution to do Exception Logging combined with Error Handling in my ASP.Net MVC 1.0 application. I've read lots of articles, including Questions posted here on StackOverflow, which all provide varying solutions for different situations. I am still unable to come up with a solution that suits my needs. Here are my requirements: To be able to use the [HandleError] attribute (or something equivalent) on my Controller, to handle all exceptions that could be thrown from any of the Actions or Views. This should handle all exceptions that were not handled specifically on any of the Actions (as described in point 2). I would like to be able to specify which View a user must be redirected to in error cases, for all actions in the Controller. I want to be able to specify the [HandleError] attribute (or something equivalent) at the top of specific Actions to catch specific exceptions and redirect users to a View appropriate to the exception. All other exceptions must still be handled by the [HandleError] attribute on the Controller. In both cases above, I want the exceptions to be logged using log4net (or any other logging library). How do I go about achieving the above? I've read about making all my Controllers inherit from a base controller which overrides the OnException method, and wherein I do my logging. However this will mess around with redirecting users to the appropriate Views, or make it messy. I've read about writing my own Filter Action which implements IExceptionFilter to handle this, but this will conflict with the [HandleError] attribute. So far, my thoughts are that the best solution is to write my own attribute that inherits from HandleErrorAttribute. That way I get all the functionality of [HandleError], and can add my own log4net logging. The solution is as follows: public class HandleErrorsAttribute: HandleErrorAttribute { private log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); public override void OnException(ExceptionContext filterContext) { if (filterContext.Exception != null) { log.Error("Error in Controller", filterContext.Exception); } base.OnException(filterContext); } } Will the above code work for my requirements? If not, what solution does fulfill my requirements?

  • Factories, or Dependency Injection for object instantiation in WCF, when coding against an interface

    - by Saajid Ismail
    Hi I am writing a client/server application, where the client is a Windows Forms app, and the server is a WCF service hosted in a Windows Service. Note that I control both sides of the application. I am trying to implement the practice of coding against an interface: i.e. I have a Shared assembly which is referenced by the client application. This project contains my WCF ServiceContracts and interfaces which will be exposed to clients. I am trying to only expose interfaces to the clients, so that they are only dependant on a contract, not any specific implementation. One of the reasons for doing this is so that I can have my service implementation, and domain change at any time without having to recompile and redeploy the clients. The interfaces/contracts will in this case not change. I only need to recompile and redeploy my WCF service. The design issue I am facing now, is: on the client, how do I create new instances of objects, e.g. ICustomer, if the client doesn't know about the Customer concrete implementation? I need to create a new customer to be saved to the DB. Do I use dependency injection, or a Factory class to instantiate new objects, or should I just allow the client to create new instances of concrete implementations? I am not doing TDD, and I will typically only have one implementation of ICustomer or any other exposed interface.

  • Logging erros in SqlLite database from C# Windows Forms Application

    - by Ismail S
    I'm developing a win app in C# which communicates to a WCF Service. I want to log exceptions that are thrown on client to be logged in Sql Lite Database (Win app is using Sql Lite database for storing data locally). And then later it should be sent to the wcf service when required so that it can be useful for support/analysis/application improvement. I want a method which can be directly called in every catch block simply by LogHelper.Log(ex). I would like to know if anyone has done it through Enterprise library or used any good practice for such situation?

  • Database and logic layer for ASP.NET MVC application

    - by Ismail
    I'm going to start a new project which is going to be small initially but may grow to big over the years. I'm strongly convinced that I'm going to use ASP.NET MVC with jQuery for UI. I want to go for MySQL as database for some reasons but worried on few things. I've a good years of experience working on SQL Server databases and on one project I've had a bad experience creating and managing stored procedures on MySQL database. I'm totally new to Linq but I see that it is easier to use once you are familiar with it. First thing is that accessing data should be easy. So I thought I should use MySQL to Linq but somewhere I read that it is not directly supported but MySQL .NET connector adds support for EntityFramework. I don't know what are the pros and cons of it. I would love if I can implement repository pattern as it allows to apply filter in logic layer rather than in data access layer. Will it be possible if I use Entity Framework? I'm not clear on how I should go about all this or I should just forget every thing and directly use SQL to Linq on SQL Server. I'm also concerned about the performance. Someone told me that if we use Entity framework it fetches lot of data and then filter it. Is that right? So questions basically are - Is MySQL to Linq possible? If yes where can I get more details on it? Pros and cons of using EntityFramework with MySQL? Will it be easy to access data using EntityFramework with MySQL? Will I be able to implement repository patter which allows applying filter in logic layer rather than data access layer (when I use EntityFramework with MySQL) Does it fetches hell lot of data from database and then apply filter on it? If it sounds too many questions from my side in that case, if you can just let me know what you will do (with a considerable reason) in this situation as an experienced person in this area, that should answer my question.

  • Wrappers of primitive types in arraylist vs arrays

    - by ismail marmoush
    Hi, In "Core java 1" I've read CAUTION: An ArrayList is far less efficient than an int[] array because each value is separately wrapped inside an object. You would only want to use this construct for small collections when programmer convenience is more important than efficiency. But in my software I've already used Arraylist instead of normal arrays due to some requirements, though "The software is supposed to have high performance and after I've read the quoted text I started to panic!" one thing I can change is changing double variables to Double so as to prevent auto boxing and I don't know if that is worth it or not, in next sample algorithm public void multiply(final double val) { final int rows = getSize1(); final int cols = getSize2(); for (int i = 0; i < rows; i++) { for (int j = 0; j < cols; j++) { this.get(i).set(j, this.get(i).get(j) * val); } } } My question is does changing double to Double makes a difference ? or that's a micro optimizing that won't affect anything ? keep in mind I might be using large matrices.2nd Should I consider redesigning the whole program again ?

  • TabPage Validating event firing when clicked on the currently selected tab

    - by Ismail S
    I'm doing things as said in How do I prevent the user from changing the selected tab page in a TabControl? Things are working fine. But the validating event of tabpage1 occurs if I've tabpage1 is currently selected and user clicks on tabpage1 itself. and later when user clicks on tabpage2 validating event for tabpage1 doesn't fire. What happens is if I do e.Cancel in validating event of tabpage1, in the above case, when user clicks on tabpage1 by mistake having tabpage1 already selected, it will prompt user that "Do you want to stay on current tab to save data or move from the current tab?". and if user clicks Stay but doesn't do any changes. And then when he correctly clicks tabpage2, Validating event of tabpage1 is not firing. I've uploaded the sample application here. You can run and see the behavior to properly understand the problem
