There is a free integrated version of Axalis Icon workshop knocking around for VS users. I found it via Scott Gu's blog, where he recommended it.

Problem Statement: How to know if unmanaged com object is deleted from memory.
Problem Description: I have unmanaged object instance in one class. When closing application this object is is destructed from other part of code. And it also comes to point where object is member of class to do some final clear stuff. When it tried to access this com object (which has already been deleted from memory) it throws memory access violation error.
Is there any way to know if this object still exist?
Thanks,
AksharRoop

I hope I atleast know this!!
The object is not null. It holds a pointer to an object. so here it is a 'dangling ptr' kind of situation.
|
|

Not so much "dangling pointer", but orphaned. The only way to see if it still exists is to check the pointer to it for null. If you're worried about orphaning pointers, make sure you're those pointers to other objects are null before you kill the parent object.

You should use database to fatch data from forms.
If you can think then I Can.
|

types a code ->select the database/dataset/datatable(This depends on your needs) to search you need->bind datagridview again.If you do not wish to refresh,you can use ajax.dll.

when user types a code number in the code Column...... description and price is automatically displayed
let me see.yes ,i do not understand the message .
Two kinds of situations
1: add a new textbox to input the code ,when the textbox change,the information display in the datagridview.of course,you said you want search the datagridview,so the datagridview is be filled at firt.datagridview's datasource usuall is datatable .
you can write the code like this
DataTable dt = ds.Table[0];
DataView dv = dt.DefaultView;
dv.RowFilter = "ID = '"+textBox1.Text+"'";
dataGridView1.DataSource = dv;
2:I am a real jerk.I don't understand what you mean.If this is true.i am very sorry,but you could laugh whit me at my poor english.

WATIF THE USER STOPS THE SERVICE. THE USER WILL HAVE ADMINISTRATIVE PRIVILAGE....
|
|
|
|
|
Then you can't do much operating client-side. If the user is an Administrator he can do pretty much anything he want with his machine.
If you want to forbid access to some URLs, I suggest you look using a proxy server application (such as websense).
P.S.: don't shout.
|
|
|
|
|
Well, preventing the privilegies of an admin ofdoesn't sound right.. Maybe you should move your URL-checking from the local machine? And please don't shout..

You can create Application or Service which you should start at windows logon.
Service is the best way to use it. Service have the facility to start automatically.
If you can think then I Can.
