and within company name... the sub key is ...version

then with in version .... it is creating .... software\microsoft\keyname..

What you want to do is nasty, you should put the keys where people can find them, but I get why you'd want to hide stuff, for security, etc. Get rid of the Application. stuff and use the raw APIs that allow you to access the registry where-ever you like. There's tons of articles here and on google.

Use the Registry classes instead of the Application shortcuts. This will give you much greater control over what you need to do.

it is better that you answer me .
i know you can not answer to me .
jam kon kazo koozato .

is how you replied to me via email. I am replying here so you don't get my email address.

No, I don't know. Nor does anyone else. We don't use this grid. That's why I suggested you ask people who DO use it.

I'd like to allow my users to write code statements in array format, for instance

c = a + b

where a and b are really a() and b() arrays.

Any ideas how I could do this? I've checked math code parsers, but none of them seem to do arrays.

Thanks!

In what context, are you writing a library ? What are the rules for adding two arrays ?

Well the math is array math, as in c++.

OK, I clearly need to be more specific.

I'd really like to create an intellisense-capable editor that would allow my users to write and see their errors in vb.net code. However, for a few functions, I'd like add c++ type capabilities, such as:

c = a + b

where c a and b are actually arrays.

other relevant array operators are < > = - / *

Maybe the first question should be how to implement the intellisense editor.

Thanks again.

Hi,

you want to define your own type (class or struct) and use operator overloading.
Look for some articles here at CodeProject on such things as complex numbers, or big integers;
that will show you the principles.

Thanks Luc. I didn't know about operator overloading -- that's exactly what I need.

What about applying vb.net intellisense in a user editor?

Any ideas on that?!

Not sure I understand the question.

Inside Visual Studio Intellisense is at your service; it parses your project files and adds
class information to the system's .NET information and presents it while editing.

In a separate editor, you can do similar things; I have no idea some Intellisense component
from VS would be available to assist you in that. I trust big editors have it on their own,
you may (or may not!) want to have a look at Eclipse, the Java IDE started long ago by IBM.

Thanks Luc... very helpful.

i've problem in running the application using vb, i'm using visual studio 2008, then after complete my application i'm trying to run it on other computer using window xp, but the problem occur, anyone can help me why this happen and how to solve it..

What does 'the problem occur' mean ? What goes wrong ? Are you installing the .NET framework on the other machine ? Did you try to google your error message ?

so, it required NET framework to running?
thanks a lot for your superb helping.

Yes, I recommend you do some reading so you have a basic idea of what the framework you're using does, and how it works.

Hi can someone guide me to a good tutorial on how to code an HTTP server/client in VB.net? I really don't know where to start. Frown | :(

Thanks.

Check out http://msdn2.microsoft.com/en-us/vbasic/ms789075.aspx#bcl2[^]. There is an "Building a simple web server with HTTPListener" example. Or, there is one here[^].

hey, sorry, i'm not here to help you, but we are share in same problem, so next time time maybe we can help each other, maybe later can you tell about your improvemnt in this problem?

i need coding that once i enter any add or deduct quantity to data grid view and only the quantity only go to specific row...example like

Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click<br />
        With Me<br />
            If .radAdd10.Checked = True Then<br />
<br />
                .ProductTableAdapter.UpdatePrice(1.1, .Category_IDTextBox.Text)<br />
                .ProductTableAdapter.Fill(.ComputerDataSet.Product)<br />
            Else<br />
                .ProductTableAdapter.UpdatePrice(0.9, .Category_IDTextBox.Text)<br />
                .ProductTableAdapter.Fill(.ComputerDataSet.Product)<br />
            End If<br />
        End With<br />
    End Sub

UPDATE Product
SET Price = Price * ?
WHERE ([Category ID] = ?)
like this update i click on rad-10 and rad+10 whole column will add together...how do i add on specific row ....thanks

You need to change the values of the specific row, which means you need to grab the value from that one row, and change it. If you rebind then you will change them all.

(i'm stil student)haha..i don't understand...how to grad from datastore????can show some coding ...thanks......alots...if i'm using numericupdown to set the qty how i do it......

Your view has properties for items, columns and rows. So, you change a specific value by accessing that row/column and changing it.
