Hi guys!
I am a newbie to this language and I request your help. I have a text file called confirm.ini which I am trying to parse it and then load different data in the file into different text boxes.
Here is how my confirm.ini file looks like:
Directory Containing Source Files for Processing: C:\text\Users\
Directory to Archive Processed Files: C:\text\Archive\
----------------------------------------------------------
Configuration:
Users: WWWW
Accounts: 3fffffff
AR: 212222
AD: 232313
Participants:
Amount: 23
Fee: 4444444
-------------------------------------------------------------
Basically I need to load each fields above, i.e. Users value "WWWW" into Users.text and then Accounts value into Accounts.text and so on. Please help, I am kind of lost in this matter.
I appreciate your help in advance.

you can read ur file into a string variable ( ex: text) and use follow methods or properties:
<br />
string find;<br />
find=text.Substring(int_start_index,int_length);<br />
find=text.Replace(old_value,recently_value);<br />
and ....<br />
<br />
note : use using System.IO; for working with files.

i use following code , but my all of my listbox items show DataRow, and display member didnt show. 
note: i bind datasource of listbox on runtime.
private void li_name_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e)<br />
{<br />
e.DrawBackground();<br />
<br />
Brush myBrush = Brushes.Black;<br />
long AID=0;<br />
DataRowView D_Author_name=(DataRowView)li_name.Items[counter_item];<br />
string Author_name=D_Author_name["Name"].ToString().Trim();<br />
Authors author=new Authors();<br />
AID=author.find_AuthorID(connection.make(),string_process.editition(Author_name));<br />
counter_item=counter_item+1;<br />
if(AID !=0)<br />
{<br />
myBrush = Brushes.DarkGray;<br />
}<br />
e.Graphics.DrawString(((ListBox)sender).Items[e.Index].ToString(), <br />
e.Font, myBrush,e.Bounds,StringFormat.GenericDefault);<br />
e.DrawFocusRectangle();<br />
<br />
<br />
}
<br />
public class Authors<br />
{<br />
OleDbConnection con;<br />
OleDbCommand cmd;<br />
<br />
public long find_AuthorID(string cnstring,string Author_name)<br />
{<br />
try<br />
{<br />
con=new OleDbConnection(cnstring);<br />
string cmdstr="select id from authors where name='" + Author_name.Trim() + "'" ;<br />
int id=0; <br />
cmd=new OleDbCommand(cmdstr,con);<br />
cmd.CommandType=CommandType.Text;<br />
con.Open();<br />
OleDbDataReader rd;<br />
rd=cmd.ExecuteReader();<br />
if (rd.Read())<br />
{ <br />
<br />
id=(int)rd[0];<br />
con.Close();<br />
<br />
return id;<br />
<br />
}<br />
else<br />
{<br />
con.Close();<br />
return 0;<br />
<br />
}<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message);<br />
return -1;<br />
<br />
}<br />
}<br />
}<br />

This is the problem, you're getting the ToString of the DataRow class. If you want to draw the DisplayMember then you'll need to use reflection to get the value of the property given in DisplayMember, you can then use that as the string.
If DisplayMember will always be a the value from a column of the row then you can use that as the key for the columns. I.e. cast the ListBox.Items[e.Index] to a DataRow and then retrieve the value from the columns.
So if DisplayName is the column name:
ListBox tempListBox = (ListBox)sender;
DataRow dataRow = (DataRow)tempListBox.Items[e.Index];
e.Graphics.DrawString(dataRow.Columns[tempListBox.DisplayMember].Value, ...); I'd suggest optimising the code as well because even you're snippet has a lot of boxing and unboxing going on and if the list contains more than a few items then you're going to take some serious performance penalties.

I'm not sure based on your code but there'll be something wrong with the layout logic somewhere.
I did have a fantastic example from my "Programming Visual Basic .NET" book by Balena but can't find the code at the moment, take a look at the source code in this[^] article in the meantime.

Well, your approach to database development will never scale to real world apps, but I guess it's fine for now. You're passing the text of both radio buttons to the database. It does not surprise me that you don't have three fields to save against. You probably want something like this:
string idata = "insert into db1 values('"+txtID.Text+"','" + rbmale.Checked ? "M" " "F"+"')";
This stores M or F, depending on if rbMale is checked or not.

Dear Reehan Bhai,
Please change your Insert query as following:
String idata="Insert into db1 values("+txtID.Text+","+(rbmale.Checked ? rbmale.Text:tbfemale.Text+")";
I think above query must solve your problem.

I am using ClickOnce in Visual Studio 2005 Express. Everything is working fine. I am publishing my application to a web link:
http://andromeda/RuntimeConfig/RuntimeConfigTest.application
The issue I have is that when I try to create a desktop shortcut to the address, I get an error that states the shortcut is not valid. I guess it's expecting an absolute file path, or UNC path. It works with an IE favorite link, but when I click the link IE opens then closes immediately after my WinForm app displays. Is there any way to create a http:// shortcut link while preventing the browser from opening?
Thanks
Raffi
