I have a big problem to upload one csv fil to mysql database.
i have a big csv file with many records and column
Eks.:

642 0993A001 BJ-642/black 790sh f BJ300 330 Canon blækpatron, sort (BJI-642BK) Canon 97,11 0
665 1009A001 BJC-643/black f BJC-800 820 880 Canon blækpatron, sort (BJI-643BK) Canon 157,43 0

i load the file like this

StreamReader input = new StreamReader(@"c:\test.csv");
string inputLine = "";

while ((inputLine = input.ReadLine()) != null)
{

but now i need just to take ManArticleNo and Price from the inputLine
my input line has all the row, how can i split or somthing to take just that column i need ?

string tr = inputLine.?(?);

}
input.Close();

string[] columns = inputLine.Split(',');//',' for .csv, '\t' if tab delimeters etc.

then you just reference the index of the columns you want e.g.

string ManArticleNo = columns[0];//or whatever index

then you do the database update stuff

My opinion is... If someone has already posted an answer, dont post the SAME answer

tab key in a textbox

Hi, I want to give a value in a textbox when the 'tab' key is pressed in another textbox. My code is this:
private void textBox1_KeyPress(object sender, KeyPressEventArgs e)
{
if ( (e.KeyChar.Equals(('\t'))) || (e.KeyChar.Equals(Keys.Tab)) ){
this.textBox2.Text = "hola";
}
}

But the only way that it works is to set the 'Multiline' and 'AcceptsTab' properties to be true (both properties at the same time, unless it not works). And the problem is that on this way, to press the tab key the focus not change to another textbox.

Anybody knows a better way?

Why not use the Leave or Validated event for this ?

It is a good alternative. I can use the keyPress event for the intro key, and the Leave event for the tab key.
Ok, thanks

dont know the error code but when i had a vista issue, it was to do with the project manifest, maybe you could look at that. Its to do with trusting the application or something

My opinion is... If someone has already posted an answer, dont post the SAME answer

but what is this project manifest

Re: windows service created in 2005 .net is not running in vista

something to do with security, somes vista apps seem to want it to run. Its somesort of xml coded file that determines how the application should run, i.e. as administrator or user etc.

I cant remember in detail have a look at this or search c# manifest or something

Why on earth would you want to design a combobox with no dropdown?

I hate it when people respond with "WHY DO YOU WANT TO DO THAT?"

The OP asked HOW, not WHY!!! Regardless of your reasoning!

Not that it matters now but the reason that I asked why was so that I could get a better handle on what the OP was really trying to do, the better to formulate a sensible reply.

You will need to write code to parse the Excel file ( either export as csv, or use the Office interop stuff ), then write your SQL.
