Could somebody tell me how to convert a string (0 to 255 range) to a byte array?

Use the encoding of your choise and the GetBytes method:
messageArray = Encoding.ASCII.GetBytes("Hello world")
---
b { font-weight: normal; }

Hi,
Thank you very much for help. Your code just works for ASCII characters. What about the characters in the range from 0 to 255??
Thank you again,
William

That's why I said that you should choose an encoding. Use the encoding that was used to create the string.

b { font-weight: normal; }

Dim textConverter As New System.Text.UTF8Encoding
Dim bytes() As Byte = textConverter.GetBytes("Text to convert")

Hi friends,
One problem i am stuck in please try to help.
I want to create a code where, when user clicks one row of the datagrid filled with data, the particular column value for e.g. the value of second column of the selected row should be visible on the text field present on the same form after a click of a button.
The sequence will be
1. First user click and selects one row
2. Then clicks a particular button
3. As click event is fired the value present in the second column of the selected row displays in the textbox present on the same form.
Try helping out please.

I am looking to create a program similar to PcAnywhere so I can connect to various servers. I want to create an interface similar to theirs where it lists the servers that you have configured using a list view control. I want it to list the contents of the folder where I will save the configuration files and display the configuration information in the file for its respective columns.

Hi Guys
I was wondering if anyone could help me with code that loops through an application taking note of all the forms and controls that are present. Users can then dynamicall add validation rules that would be stored in a DB for example a user can select an orders form and then add a rule like specifying length of oreder number but this would be at runtime.
I want to avoid "hard coding" validations and allow users to set them up themselves.
There are 10 kinds of people in this world. Those that understand binary, and those that do not.

i am working on a listview and i am looking for a way to make an item on the listview not Visible , i didn't find how to do this ...
anyone have any idea ?

You could always set the column width equal to zero.

i can't set the nodes width equal to zero ....

Idividual items in the ListView cannot be made visible/invisible. Using the standard controls, the only way to make an item not show up is to removed it from the list.

Are there any helper tools or addin that can make it easier to analyze and understand somebody else's source code written in VB.net and C#?
Example tools might be
1) a tool that generates flow chart of which method is getting called from which method;
2) a tool that displays the call stack with ALL the values at a given stage of program execution
3) A tool that shows from where all a particular variable is being accessed, being set.
4) A tool that shows file dependencies to point out which are the BASE files to start studying.
5) Any other tools. I am sure there can be other types of tools also.
Thanks,
Rajesh.
Thanks

This might be helpful.

The free version is limited but still useful.
I think tools such as Resharper have class browsing built in. But it's not free and is C# only.
I'm sure the other guys will suggest more tools.

Bluärgh! Please use the pre tag when posting larger blocks of code. It's virtually unreadable in that form.
