        Last week I installed Microsoft Dynamic 4.0 on my virtual machine and I found that it will be helpful for beginner like me, if there is a step by step installation guide. Lets start with OS selection.

1. You can use Windows Server 2003 or later server version. I had Windows Server 2003 R2.

2. Install latest service pack for OS you installed.

3. Install Internet Information Service.

4. Install Active Directory.

5. Configure DNS Server.

6. Create new user for domain and make him member of Administrators group.

7. Install SQL Server 2005 with Reporting Service and Analysis service.

8. Configure new account as service account for Report Server and Analysis server.

9. Install Visual Studio 2008.

10. Start installation of CRM 4.0

11. Enter display name for your Organization.


12. Next step is to select installation path, you can leave this as it is or select specific folder,


13. Next select website for CRM, I choose new website with different port address in my case it was 5555 as shown in image below,


14. Next you need to enter URL for Reporting server.

15. Next you have to select Organization Unit. Click on Browse button and select the root node of your domain in my case it is chirag.


16. On next step you need to specify security account, choose the one you created in step 6. Enter the password in password textbox and click next.

17. Select your local machine as Email Router setting or select specific machine on domain which you are using at email server. I chose my local machine so localhost.

18. Once you click next you will see System Requirements screen. If Domain user, SQL Server Reporting Service and ASP.NET are installed properly you will receive no error or warning else you will receive error message. I received following errors,


19. If you receive error message for SQL Server or SQL Server Reporting Service don’t be afraid. Open Services from Start – All Programs – Administrative Tools – Services. Check whether SQL Server Agent is running. If not right click on service and select property. Select Startup Type as Automatic and click on start button.

20. Another common error is for Indexing service. Follow the steps mention in point 19 to start Indexing Service.

21. You can see a warning mentioning Verify Domain User account SPN for the Microsoft Dynamics CRM ASP.NET Application Pool account. This will usually shows when you add specific domain account for security account in step 16. You can solve this warning now or after installation by following steps mentioned at http://billoncrmtech.blogspot.com/2008/08/now-i-am-master-tips-for-running-crm-40.html

22. If System Requirements screen show no error or warning on next step installation will be started.

23. Finally you will see following screen, this means your CRM is installed.

        Today while working with JQuery-Ajax, I found an interesting error. I have used $.ajax() function to retrieve data from remote page. While testing I found that the page always show error : XML Parsing Error: no element found. Error does not contain specific information about the source of error. The common reason for XML Parsing Error: no element found is missing closing tag for one or two html element, so I double checked everything to make sure not miss any closing(</td> </tr>) tags.

        After searching for while I found that somehow ASP.NET treat the response of page as XML document and that’s why we receive XML Parsing Error: no element found error.

        To solve this error I added a line Response.ContentType = "text/HTML" to .cs page. This line tells ASP.NET runtime that response is HTML text and not XML.

           We all may have use JQuery in our application to build rich UI. While working with JQuery today I found that JQuery is not working on some pages where I have user mootool scripts. I search on net and found a very descriptive solution at JQuery site.

           According to this article the reason for JQuery conflict is the use of $ function. mootool and prototype.js files have their own $ function. So when we use $() and try to access JQuery (as it is shorten form of jQuery()) browser is not able to resolve which $() function it has to use. To avoid JQuery conflict we have to use jQuery.noConflict() function.

           While you read JQuery site article you may have observe the order of java script files added to web page.  Read carefully and you find that you have to add other libraries first and then add JQuery library to page. If you change the order and add the JQuery library first, either mootool(or other library which you have included) or JQuery will not work.

       We all know what JSON is and how it helps to build rich application. Recently during free time I was playing with JSON. It is easy to pass simple data types between server and client however its bit tricky to work with complex data types.

        Consider that we have Student class with FirstName, LastName and City properties. You can pass array of Student object from client to server using JSON.stringify() method. See the code,

function LoadAjax() 
    var t = [
             { FirstName: "Chirag", LastName: "Darji",City:"Ahmedabad" }, 
             { FirstName: "Chirag", LastName: "Darji",City:"Ahmedabad" } 
                { values: JSON.stringify(t) }

Fig – (1) Passing complex data type using JSON

          Here we are passing array of two customer object from client to server using JSON. I have used JQUERY load method which use POST method to send the data to requested page. You can convert this parameter to Student class using following code,

var json = new DataContractJsonSerializer(typeof(List<Student>));
var stream = new MemoryStream(Encoding.UTF8.GetBytes(Request.Form["values"]));
List<Student> lstStudents = (List<Student>)json.ReadObject(stream);

        We have used FCK editor as an HTML editor for our recent project. It is one the best and easy to integrate HTML editor available free. When I test the editor on local server and it works fine. However when we add image using FCK editor the image path is relative to tour webpage. So if you have created an email template using FCK editor and you sends email to your customers they will not able see the image.

Set Full Image Path in FCK Editor

Fig – (1) Relative Image path in FCK editor

              We need to use full image path in FCK editor to display the image. You can change SetUrl function at following place to set full image path in FCK editor. You can find SetUrl function in fck_image.js fule at “FckEditor\editor\dialog\fck_image”. Below is the original function,

function SetUrl( url, width, height, alt )
    if ( sActualBrowser == 'Link' )
        GetE('txtLnkUrl').value = url ;
        UpdatePreview() ;
        GetE('txtUrl').value = url ;
        GetE('txtWidth').value = width ? width : '' ;
        GetE('txtHeight').value = height ? height : '' ;
        if ( alt )
            GetE('txtAlt').value = alt;
        UpdatePreview() ;
        UpdateOriginal( true ) ;
    dialog.SetSelectedTab( 'Info' ) ;

Fig – (2) SetUrl function of FCK Editor

          Change GetE(‘txtUrl’).value = url, first line in else condition to GetE(‘txtUrl’).value = “http://www.xyz.com” + url. See the changed line below,

GetE('txtUrl').value = 'http://www.xyz.com' + url ;

Fig – (3) Changed function.

           Save fck_image.js  file and now check the image path. FCK editor will take full image path instead of relative.

Set Full Image Path in FCK Editor 2

Fig – (4) Full Image Path in FCK Editor


Set Full path for Flash File

            Same way you have to change fck_flash.js file at FckEditor\editor\dialog\fck_flash folder to set fill flash path in FCK Editor.
