so you got an IT degree and worked for months now, but you fail to understand try-catch?
I strongly suggest you read up on exception handling and hurry applying it everywhere.
IMO it is the shortest route to creating reliable applications.

Check each string as you load from the DB to ensure it a valid address (does not contain invalid chars and has an '@' symbol... I don't know if there are more requirements for e-mail addresses, but you can find these easily online).

i'm selecting all the email address in the db and using a while loop to send out the email.
i manually went through the email addresses today and they looked ok. ie @'s and .'s but know i don't know what to try and was woundering if these a way i can get the code to tell me which address is wrong

I figured you are sending it to multiple recipients in one send. If you are sending to one recipient at a time, then do what the other responders suggested. Otherwise, you can find a regex for checking email here[^] (I did not check this, but it was the first result from google). Hope this helps,

Thank you so much

Well, you don't have a choice there. You either set the STA or you don't use the Media Player control.
Why do you have to use MTA?? You can create threads yourself all you want without it...

hi thanks for getting back to me friend
i have to MTA as i am using the Intel Mobile SDK to monitor Power and Network events and as far as there web site goes i have to use MTA in order for it to function correclty.
i have ran my program with STA and the events do not work
thanks

In that case, you can try this. You have to keep the Main in your code STA or you lose ActiveX controls. Start a seperate thread, setting its Apartment to MTA before you actually Start the thread. All of your code using this library would have to be running under this thread in order to work (per Intel). I don't know if it'll work, and it might take a large rewrite of your code to find out.
Your best source of information on this problem is actually going to be Intel.

Yes, things like that can work. We once did such things.
The way I understand it, you can choose the overall MTA/STA status, and then deviate from
it for each new thread you create.
There is one little caveat: for each thread you can set the appartment model only once,
but that should pose no problem.
PS: I don't recall how prefabricated threads (ThreadPool, BackgroundWorker, ...)
behave in this matter.

trying to write a c# datagridview wrapper class, and i'm having problems setting my form object to the class dgv wrapper.
error: "Cannot implicitly convert type 'System.Windows.Forms.DataGridView' to 'test.Grid'. An explicit conversion exists (are you missing a cast?)"
form code:
breaks on:
"Grid i_grid_o;
i_grid_o = dataGridView3;
i_grid_o.UpdateGrid(i_grid_o);"
wrapper class code:
"using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
namespace test
{
class Grid : DataGridView
{
DataGridView i_grid_o = new DataGridView();
//ctor
public Grid()
{
}
public void UpdateGrid(DataGridView a_grid_o)
{
i_grid_o = a_grid_o;
MessageBox.Show(a_grid_o.ToString());
//DataGridView a_grid_o, a_table_o
//a_grid_o.Update(a_table_o);
}"
anyone can help, will greatly appreciate it!

Member 3946582,
You just need to do: i_grid_o = (Grid)dataGridView3;
Also, on a side note, you don't need to create a DataGridView in your Grid class. You could change your code to:
private DataGridView _gridView
public Grid(DataGridView dataGridView)
{
_gridView = dataGridView;
}
Then, when ever you want to create a Grid object, just do:
Grid i_grid_o = new Grid(dataGridView3);
i_grid_o.UpdateGrid();
Regards,
Gareth.

Hey all,
I have a simple listview question. When a row is clicked, I can get info from a particular column like this:
listView1.FocusedItem.SubItems[0].Text
But how can I get the column dynamically?
Thanks!

I don't have a lot of experience with ListView, but after a quick glance at the API, in your Click method, I think you can use the event args 'e' like:
int colIndex = e.Columns.Index();
I might be wrong though, like I said, never used it much.

I couldnt figure that way out :s lol, still learning 
|

First generate the click method: Go into the ListView's events in the form design or if you've coded the ListView:
listView1.ColumnClick += new ColumnEventHandler(listView1_ColumnClicked);
Half way through writing that, Intellisense will say press tab to auto generate method.
Then inside the method, the code I previously wrote should do the job.

I have some problems with reading and writing to an Intranet directory. I always get an permission exception.
The executable file is shared on an NTFS network volume. There is no problem to read and write files directly in executable home directory.
When I try to read/write outside the folder I get an exception.
The next step was to create an PermissionSet but I got an Security Exception.
How I can read/write files
thanks in advance
