how to iterate through a hashtable

if you have a hashtable and if you want to extract key/value pair;
iterating through a hashtable:
//declare and define
Hashtable htItem = new HashTable();

//now loop thru the key /value pair

foreach (DictionaryEntry de in htItem)
{
splstitem[de.Key.ToString()] = de.Value.ToString();
}
*********************************
suppose if you have acworkflow attached in your custom splist and if you wanna update the workflow task belwo is the LOC:
we need to use the SPWorkflowTask.AlterTask. the most imp.part here is
ht: a hashtable.


public string UpdateWorkflowTasks(Hashtable ht, int TaskID)
{
string strRequestorsID = string.Empty;
using (SPSite site = new SPSite(strUrl))
{
using (SPWeb web = site.OpenWeb())
{
web.AllowUnsafeUpdates = true;
try
{
SPListItem taskItem = null;
SPList listTasks = web.Lists["Tasks"];
taskItem = listTasks.Items.GetItemById(TaskID);
SPWorkflowTask.AlterTask(taskItem, ht, false);
strRequestorsID = Convert.ToString(taskItem["strRequestorsID "]);
}
catch (Exception ex)
{

}
web.AllowUnsafeUpdates = false;
}
}
return strRequestorsID;

delete items in a splist: MOSS 2007

just putting few LOC to delete a listitem from a splist :
using (SPSite site = new SPSite(strUrl))
{
using (SPWeb web = site.OpenWeb())
{
try
{
SPQuery objQry = new SPQuery();
objQry.Query = strQuery;
objQry.ViewAttributes = "Scope=\"Recursive\"";
SPListItem objlstItem = web.Lists[strLstName].GetItems(objQry)[0];
objlstItem.Delete();
}
catch (Exception ex)
{

Dynamic method invocation in .NET 2.0 using a WSDL

Recently I have come across a problem with generating proxy class on-the-fly by inputing a
WSDL file:
After a little bit of googling I came to partial success!!!
Below is the code for same:
Has anybody having a well furnished code? / comments , how to improve it??

Consuming Composite Web Service

If anyboy is having problems with Composite Web Services?
here is the code for accessing the Web Service craeted using Composite Studio.
Add a web reference in VS 2005 to the Web site you have created:
http://myserverip:1100/myServices/WSvTBLAPPLNCountry?wsdl

Copy/ paste the code below either in the page_load or button click event:

#region PopulateCountry

objgeorefcountry.Credentials = nc;

CountryyWebReference.VwCountryResponse objresponse = objgeorefcountry.VwCountry(objCountryRow);
CountryyWebReference.VwCountryResponse objres= objcountry.VwCountry(objCountryRow);
DataTable dt = new DataTable();
ArrayList arryLstCountry = new ArrayList();
for(int i = 0; i < objresponse.VwCountry.Length;i++)
