In order to analyze what is wrong, you should investigate the behavior, look for symptoms, find the place where it starts to go wrong. That's called debugging, it is an intrinsic part of software development, you need to learn that.

well, if you already have source code written and need help, feel free to post the relevant code and tell us what what is wrong with it.

So do I.
You need to tell us what is wrong first. How do I know what is the problem?

Congratulations, you win the moron of the day award.
1 - we don't know what book you're using
2 - if we gave you source code, it wouldn't help you pass your course, it would help you fail
3 - you should talk to your teacher if you're stuck

What privacy. Can work this when I log as guest or not
|

A guest usually can't "snoop" in the system. Just as a guest in your house shouldn't be looking in the cabinets, so is the security of your Windows'. It assumes that guests behave as such and that they are less privileged than full-blown users.

It doesn't work because the Guest account has permissions to do just about nothing. IIRC, it should fail on the GetObject line since you need at least User level access to get a WMI object.

I have written a program that it has a grid with about 800 person information
my database is access but the speed of load and sqrulling the grid is low .
what shoud I do . please help me about this program .
|
|
|
|
|
Your question isn't answerable. Since we know nothing of your code, how your populating the grid, the structure fo the database, the query you're using to retrieve the data, whether the database is local to the machine or on a remote server, ...., no nothing, ... there's nothing anyone can tell you that would do you any good.
|
|
|
|
|
How many people are accessing the access-database?
Reading 800 records into memory is something that takes time - you might want to try to limit the amount of records that you are reading. You could do this by adding extra filter-options, for example, showing only the Persons from Tokyo (one place at a time).
You may also want to consider upgrading to SQL Express, a free SQL Server version that has a somewhat better performance as a database-server.
Lastly, you might want to check your SQL-statements and indexes, and run them through a profiler

Hi,
since you did not show any code and did not provide much detail, here is a wild guess:
maybe you are adding records to the GridView/DataGrid/DataGridView one by one, causing Windows to recalculate and repaint the grid every time, instead of just once. There are ways to improve this:
- keep the grid invisible till it is filled;
- use SuspendLayout() and ResumeLayout() once;
- use AddRange() instead of Add();
- use data binding.
If the wild guess is way off, tell us more and/or show code.

i am using same user control in two forms . i need to get the form name which is using the user control currently .and the form name i should get inside the user control methods.pls help me
|
|
|
|
|
What do you mean by name ? The text on the form, or the class name ? The control has owner and parent properties. You can use the is keyword to find out if the parent is an instance of a specific class. However, doing so is poor design, your form should work regardless of where it is. If it has one behaviour for forma and one for formb, I'd add a property you can set to choose which behaviour you require.
