Loading External JavaScript files


Suppose this is our external javascript file content.

(customscript.js)

It consist of a simple function

function SayHello()
{
    alert(‘Hello World’);

}



 


It is placed at the following path   ..\ISV\ExtJS. i.e. within ExtJS folder inside ISV.


Place the following code in the form load of an entity’s form.


var scriptElement=document.createElement("<script type=’text/javascript’>");

        
scriptElement.src="/isv/ExtJs/customscript.js";


document.getElementsByTagName("head")[0].insertAdjacentElement("beforeEnd",scriptElement); 


SayHello();






At times, it would work properly however sometimes it would throw “Object expected” error. It is because browser load JavaScript files asynchronously. If the script isn’t loaded we would get the error.


So here we need to make use of onreadystatechange event. 


So we would modify our script as following 


 


var scriptElement=document.createElement("<script type=’text/javascript’>");

        
scriptElement.src="/isv/ExtJs/customscript.js"; 


scriptElement.attachEvent("onreadystatechange",loadScript); 


document.getElementsByTagName("head")[0].insertAdjacentElement("beforeEnd",scriptElement); 


function loadScript()

        
{ 


if(event.srcElement.readyState=="loaded" || event.srcElement.readState=="complete")

        
{ 


    SayHello();

        
}


}


 


 


Or we could also using XmlHttp request object to load the external file.


var url="/isv/ExtJs/customscript.js"; 


var xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");

        
xmlHttp.open("GET",url,false);


xmlHttp.send(); 


eval(xmlHttp.responseText); 


SayHello();


 


Bye..

Error parsing Solution. Value does not fall within the expected range.
	


	
	
	

		

Hi,


I started getting this error while deploying the site definition solution in SharePoint ( it was visual studio 2008) . I also had a web application in the same solution.


I removed that web application and then it got deployed without any error. However that web application was there earlier as well but it wasn’t giving error before. Not sure what exactly caused the error.


Anyways, I hope it would be useful !


Bye.

To get the value for Person or Group Column Type after removing the special characters from it, use this function


private string  GetValue(SPListItem item, SPField gpField)   
{    
    string currentValue = item[gpField.Title].ToString();    
    SPFieldLookup field = (SPFieldLookup)gpField;    
    SPFieldLookupValue fieldValue = (SPFieldLookupValue)field.GetFieldValue(currentValue);    
    return fieldValue.LookupValue;    
}


to call it


string strName = GetValue(spListItem, spListItem.Fields["fieldName"]); 


 


Bye..

Pre-generated XmlSerializers (CrmService)for Plugin
	


	
	
	

		

Please refer this article


http://uwekaessner.spaces.live.com/blog/cns!21916E8556D908E!175.entry?sa=260352433


I am just writing out the main steps from it and the steps where we need to strong sign the assembly so that it could be used within Plugin.


Add web reference to CrmService.asmx


http://servername/mscrmservices/2007/CrmService.asmx


Go to “web references” folder. 


Copy Reference.cs file to a new folder.


Rename it to CrmServiceSerialized.cs


Open the CrmServiceSerialized.cs class, rename the class to CrmServiceSerialized.


namespace MyApplication.CrmServiceSerialized


Change the CrmService property 


public CrmService(string url) {


           this.Url = url;


Complie it to a dll


If we want to use the Serialized dll within Plugin we need to strong sign it


sn.exe -k g.snk 


csc /t:library /out:CrmServiceSerialized.dll CrmServiceSerialized.cs /keyfile:g.snk


To pre generate a strong named XmlSerializer dll


sgen.exe /p CrmServiceSerialized.dll /compiler:/keyfile:g.snk


Next again open CrmServiceSerialized.cs and comment out all occurrences of [System.Xml.Serialization.XmlIncludeAttribute using Find and replace.


Next we need to add the attribute 


“[System.Xml.Serialization.XmlSerializerAssemblyAttribute(AssemblyName = "CrmServiceSerialized.XmlSerializers")]” 


to the “CrmServiceSerialized” class.


Again generate the strong name assembly using the same key


csc /t:library /out:CrmServiceSerialized.dll CrmServiceSerialized.cs /keyfile:g.snk


Now we can add reference to CrmServiceSerialized.dll in our plugin to use it. Here also need to place CrmServiceSerialized.dll  and CrmServiceSerialized.XmlSerializers.dll to the GAC.
