That gives "110111", not "01010101".

I think that he meant 0x55.
If you want it padded with zeroes, use the PadLeft method:
Convert.ToString(Temp, 2).PadLeft(8, '0')
Despite everything, the person most likely to be fooling you next is yourself.

I try not to make assumptions.

No.
byte b = 55 ;
System.Text.StringBuilder sb = new System.Text.StringBuilder() ;
foreach ( char c in b.ToString() )
{
sb.Append ( System.Convert.ToString ( c - '0' , 2 ).PadLeft ( 4 , '0' ) ) ;
}
System.Console.WriteLine ( sb.ToString() ) ;

Hi,
I have a simple method that checks if a sheet name is present in the excel file or not. The code is simple and works fine when the sheet name doesn't contain any spaces:
private bool validateExcelSheetByName(string name, OleDbConnection connection) {
bool result = true;
try {
if (connection.State == ConnectionState.Closed)
connection.Open();
var command = new OleDbCommand(string.Format("select * from [{0}]", name), connection);
command.ExecuteNonQuery();
}
catch {
result = false;
if (connection.State == ConnectionState.Open)
connection.Close();
}
return result;
}
In case I have a dot and a space in the sheet name (for example 'My. Sheet'), I get an exception saying:
Invalid bracketing of name 'My. Sheet$'.
I store the sheet name in a variable:
private const string sheetName = "My. Sheet$";
How can I fix this code so it will work when I have dots and spaces in the sheet name?
Thank you!
Andrei

You can use this code to get the schema.
DataTable dt = oCon.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, null);
Here, datatable will have a column table_name which contains names of all the sheets in the file.
Hope it helps

This doesn't help me much... I have multiple sheets in the document and after I see that a certain sheet is present I have to process it:
var command = new OleDbCommand(string.Format("select * from [{0}]", sheetName), connection);
var adapter = new OleDbDataAdapter {SelectCommand = command};
var ds = new DataSet();
adapter.Fill(ds);
connection.Close();
DataTable dt = ds.Tables[0];
foreach (object dr in dt.Rows) {
string[] array = Array.ConvertAll(((DataRow)dr).ItemArray, new Converter<object,>(Convert.ToString));
// continue processing here...
}
So I would still have problems in the case of a sheet name that contains a dot and a space as mentioned in my initial post.
Is there any workaround for this issue?
Thank you!

You can create a class and define this variable as constant.
public class Messages
{
public const string Word = "Hi";
}use it like
MessageBox.Show(Messages.Word);
|
|
|
|
|
But what if I don't need the variable as a constant
For example I have a Textbox on Form1 and its name is TextBox1, and I want it like that
string word = TextBox1.Text;
Then I can show this text stored in the variable (word) in a Message Box in the second form.
Thank you so much

Create a static class and put your string variable as a static variable in this class.
This will allow you to share value of string variable between different forms.

(IMO) That's bad design man. Better is to have properties (or get/set methods as some don't like properties)

You'll need to set the ListView control's font to one that supports open and close quotes and replace the "es with these characters.

Oh I forgot to check "Ignore HTML tags in this message (good for code snippets)" for above post.
@Ravi Bhavnani: I tried to change ListView control's font but the problem wasn't solved.
