Count what ?

Count will be incorrect as finally will be executed all the time. Declare a variable and increment it in each catch block.
Assaf82 wrote: or even if i don't put the try catch block how i can count the error
I think it's not possible. When an unhandled error occurs, application will stop execution.

DharmarajNagarajan wrote: use a flag variable
It is not possible to use flag variable to count the number of error. when any one error will occer it will jump to Catch block, then directly move to finally block. so where you going to use flag !!!!
<br />
Try<br />
{<br />
first here !!!<br />
}<br />
catch ( )<br />
{<br />
if any error<br />
} <br />
Finaly<br />
{<br />
after error occured or not finaly here<br />
}<br />
so , counter is useless !!!!!

Hi, maybe this is what you want:
int errors=0;
foreach (... in collection) {
try {
...
} catch (Exception exc) {
errors++;
Console.WriteLine("Error "+errors+": "+exc.ToString());
}
}
Console.WriteLine("There were "+errors+" errors");

Change your static void main so it runs your connection form, then your main form. Or, just have your main form be the form that starts the app, and have it show the connection form on startup.

Hi Guys. I have managed to get some code to export data in my Access DB to a CSV file. Now, I have two small issues.
1. I want to mark all the records as they are exported to Y in a column named exported and only export all the records marked as N. Anybody have a suggestion on how I could do this in the export code?
2. When I open the CSV file in Excel I get a few errors. First error says that the file is in a different format than the one specified by the extention. It allows you to continue and then comes up with error "Cannot read the 1st record. The it reports yet another error which says that Excel has determined the file to be a SYLK file but not load it" but it still imports the data into Excel. Any ideas on how I get past this?
Code below:
private void toolStripButton2_Click(object sender, EventArgs e)
{
StreamWriter sw = new StreamWriter(@"C:\nefz.csv", false);
DataTable dt = m_dtCallCentre;
int iColCount = dt.Columns.Count;
for (int i = 0; i < iColCount; i++)
{
sw.Write(dt.Columns[i]);
if (i < iColCount - 1)
{
sw.Write(";");
}
}
sw.Write(sw.NewLine);
foreach (DataRow dr in dt.Rows)
{
for (int i = 0; i < iColCount; i++)
{
if (!Convert.IsDBNull(dr[i]))
{
sw.Write(dr[i].ToString());
}
if (i < iColCount - 1)
{
sw.Write(";");
}
}
sw.Write(sw.NewLine);
}
sw.Close();
}

Yeah, I guess I can do that but that is not what I want to do. I want to do the export through code. This will be done by a user once I get it to work.
Anybody else able to help out maybe or suggest something?

I am working on runtime application. I put 10 buttons and I gave random images to button's bacgroundimages.
I arranged that, when I click the button, if backgroundimage=null, it changes to normal assigned backgroundimage,
if background image is normal background image,it changes to null. One click shows bacgroundimage, second click closing this.
In form loading, all buttons's bacgroundimages are null.
I click first button and open it's backgroundimage, after I click second button and open it's backgroundimage also.
Now, i want to compare whether first clicked button's background image is the same to second clicked button's backgroundimage.
İf It is the same, I make these two buttons's enabled false, if it is not same, I make only the button's bakgoundimages null.
How can I do this.
Thans for your possible help.

Yes.
Now, be more specific about what you are trying to do and make your question meaningful.
Deja View - the feeling that you've seen this post before.
