Hi,
This is my code in the form load
string sConnectionString = "Data Source=testingserver2;Initial Catalog=test;User Id=sa;Password =agr2007$ ";
SqlConnection conn = new SqlConnection(sConnectionString);
conn.Open();
SqlCommand comm = new SqlCommand("select ModuleId from Module_Master", conn);
SqlDataAdapter dap = new SqlDataAdapter(comm);
DataSet ds = new DataSet();
dap.Fill(ds);
cmbModuleID.DataSource = ds.Tables["MODULE_MASTER"];
cmbModuleID.ValueMember ="ModuleID";
cmbModuleID.DisplayMember = "ModuleID";
I kept a break point at dap.Fill(ds) and checked. It is fetching the values from the database. But i am not able to populate combo with those values.
Thanks in advance

cmbModuleID.DataBind();<br />

To get something you must have to try once.

I think this is the third message i've seen on this subject recently. Its either coinsidence or your the same person. Either way, try searching the threads for the previous questions, and use the search box a little ways up not the one at the top of the page.

People keep asking for clarification of what you want, yet you refuse to answer them. What makes you think anyone is going to answer your question now??
Check into NTFS security. It's the only thing that's going to "lock" a folder.

well i did get your problem.. but if you're not specific in your questions you shouldn't expect very smart answers.
there's an indexOf function on the string class.. this should help you

It made perfect sense to me, what other meaning could the question have? This is the C# programming forum after all.

The problem was that (as per 'kin usual) the question was far too vague.
Yes you could probably derive the meaning of the question, but were constantly having to "derive meaning" rather than answering questions recently!
|
|
|
|
|
It made perfect sense to you because you knew about the context in which the "question" was asked. You failed to describe that context to anyone else here, thus we had to make a lot of assumptions as to what you were talking about. You know what happens when you assume, don't you??

Well, the easiest way is IndexOf:
string para = "This is a paragraph, with words and stuff.";
int search = para.IndexOf("with words and");
And then search will equal the index of the first letter of the string you where searching for, which in this case is the index of the letter 'w' in the word "with".
Of course, you can't find if it occurs again, and at what location. There's probably some article on this somewhere. Try searching CP and google.

haha, you see - you didnt derive the meaning of his question properly at all! If you read the other part of this thread he actually wanted to know how many times a string existed in another string... not the first index of a string as you have given the solution to.

Bah fine then.
The Knowledge, please don't be so vague with your questions. You make people look stupid

Use IndexOf or a regular expression.

I am new programer and for class I have to make a program that store employee data, writes them to a random access file (Employee.dat), be able to edit them, print reports, etc...
I am trying to write a line each time the user hits ADD on the enter employee form.
here is what I have
StreamWriter sw = null;
validation();
getInputValues(contact);
tring filename = "Employee.dat";
contact.MyFile = new FileStream(filename, FileMode.Append);
if (validation() == false)
{
contact.Close();
return;
}
else
{
{
try
{
sw = new StreamWriter(contact.FileName);
sw.WriteLine(contact.Serialize());
}
catch (Exception ex)
{
MessageBox.Show("eror saving contact" + contact.FileName + ex.Message);
}
finally
{
if (sw != null)
{
sw.Close();
}
}
lstContacts.Items.Add(contact.LastName + "\t" + contact.FirstName);
contact = null;
}
}
}
but it just writes over the previous employee (first line of the .dat file)
How do I make it so that it write on the next line.
Thanks for your help in advance

Hi
i think calling flush on the streamwriter should solve the problem.
just one more remark..
i would change this part here
StreamWriter sw = null;
validation();
getInputValues(contact);
string filename = "Employee.dat";
contact.MyFile = new FileStream(filename, FileMode.Append);
if (validation() == false)
{
contact.Close();
return;
}
else
{
{
to
StreamWriter sw = null;
if (!validation())
{
return;
}
getInputValues(contact);
string filename = "Employee.dat";
contact.MyFile = new FileStream(filename, FileMode.Append);
it's a bit shorter, prevents you from validating the input data twice and you don't have to open the file and then close again if the input data is invalid.

Thanks but one question. What does flush do?

streamwriter and stream use a buffer. they don't write immediately to the file.
flush forces the stream(-writer) to write down the buffer.
alternatively you can set the autoflush flag of the streamwriter to true. the streamwriter writes the data then immediatly to the file without buffering it first.
