I do not figure out what you actually mean, but I guess using the Cache might help.

Hello all...
Can any one please tell me how can we add .rpt and .cri extensions in IIS (windows 2000 with crystal reports 9 installed on the same). For crystal report 8 we need to map these extensions to "C:\Program Files\Seagate Software\WCS\Wcsinsapi.dll" but this is not the case with CR 9, so i am wondering if anybody knows how will it work for crystal report 9(CR 9).
If anyone knows how to do it, that will be a great help...

Hi All,
I am working on a project that requires handling of custom events. Some class will raise the DataEvent of RaiseEventClass. I have to implement event handler for the DataEvent in the RaiseEventClass. Please help me how to implement event handler. Please show some codes if possible.
Below is the skeleton of the class.
Thanks in advance!
public class RaiseEventClass
{
public delegate void RaiseEventDelegate(ArrayList files);
public event RaiseEventDelegate DataEvent;
public void SearchFiles(ArrayList list)
{
DataEvent(list); //raising event for testing
}
}

First you should change
A.Asif wrote: public void SearchFiles(ArrayList list)
{
DataEvent(list); //raising event for testing
}
to
<br />
public void SearchFiles(ArrayList list)<br />
{<br />
if (DataEvent != null)<br />
DataEvent(list);
} <br />
just to handle the case when no handler is attached to the event.
Then if you've got an RaiseEventClass object (call it "myObj") and want to handle the event just use
myObj.DataEvent += new RaiseEventDelegate(myHandler )
where myHandler is a function like
<br />
void myHandler(ArrayList files)<br />
{<br />
}<br />
By the way: afert typing "+= new" in the line where you attach the event you can hit <tab> twice and VS will write a handler-function for you (so you don't have to check the delegate to know exactly what kind of parameter / return you have to use)
One other comment:
you should include a "sender" parameter in every event you write (like object sender, or RaseEventClass sender - this helps you handle events from many sources in the same handler function and is always a good pattern.

Is there any way to choose and set the password of MySql Database at runtime through C# code.
Any help will be appreciated.
Thanking You

set password = password("newone"); is the query for changing password. Try passing this through ExecuteNonQuery().

Overload form2's constructor which accepts a string value as parameter. Pass the first textbox value to this when you are invoking form2.
frmTwo frtwo = new frmTwo(txtOne.text)
frtwo.show() Inside for2 constructor, assign the value to respective text box.

Please don't do this. If you want to be a better developer, you should learn about design patterns and how they help you design software. You can solve this issue using either the Observable pattern or the Model View Controller/Model View Presenter patterns. Please look at using them.
BTW - it's not Opportunity knoughts softly, it's Opportunity knocks softly.

I am not getting how it can help in passing one value other form ?

Because you don't pass values from one form to another. You create a data model and put views on the model. These views get updated when things change. It's that simple.
Suppose you want to extend this issue and have the same value updated in 20 or 30 places, using a pattern makes this trivial. Using hard coded value passing makes it complicated.

That's great. Thanks. Do you have any good links for MVC implementation on C# ?

This[^] is a good source of information. This[^] is also excellent - it's very deep and takes a lot of reading, but stick with it.

Thanks. I will take a look

I need to pass the IP address to app.config file that is created after installing the project.I got to add the web reference to run my service.
Web reference would be ..
http://202.79.41.240/Setup12/Service.asmx.
Now I need to change the IP address that gets stored in app.config file.
Thanx in advance.

XmlDocument xDoc = new XmlDocument();<br />
xDoc.Load(@"YOURPATH\App.config");<br />
if (xDoc.DocumentElement.SelectSingleNode("appSettings/add").Attributes.GetNamedItem("key").InnerText == "IP")<br />
{<br />
xDoc.DocumentElement.SelectSingleNode("appSettings/add").Attributes.GetNamedItem("value").InnerText = "genericIP";<br />
xDoc.Save(@"YOURPATH\App.config");<br />
}
But I am not sure how safe it is to handle you app config file in dynamically
