I don't think you can beat SQL Server.
Alternatively, you could make your own indexing system for the files.

SQL is to slow for this --- for what it is designed to do?
Seriously, anything you do won't beat SQL.

I can think of specialized ways to outperform SQL, especially if the records aren't in SQL to begin with. The question is whether it's worth the money (and time) to do it.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I'm no database guru, but isn't this exactly the kind of thing you'd want to use SQL server for?
Standards are great! Everybody should have one!

Have you tried defining some indexes? If the database is designed properly there shouldn't be a performance problem for this.
Loading a file with that much data is going to be very costly in terms of memory use and performance as well.

If a Relational Database is to slow for you then you better give the job to Google

Maybe I didnot state it clearly enough. I am looking for something like a HashTable, where I can find the record with a provided key, so that I dont have to join tables and then do a select statement to select that one record from the DB.
I personally have not tried the SQL Server method cuz I was told that it was too slow for the task(The team has tried it before). Is there any data structure out there that might fit this scenerio? or SQL Server is the only way?

Of course not. It is however the best conventional method.

From my experience I would want to confirm that. If they already did a research project to look at that approach you should be able to look at the project and run it etc. You may find that that they did not do something as simple as creating the appropriate index(s) to support the requirements.
Also what about the hardware, OS and Database tuning? Perhaps the machine was not appropriate to the requirements. If you have 2 gigs of data then you could use a large server (memory and processors) and possibly configure the Database to use enough physical memory to keep the records in memory at all times. I don't know squat about tuning a Relational Database and possible the OS to run one, but I would find an expert and exhaust that approach before I jumped into considering anything else.

Hi,
I would like to get the value of a cell in a datagrid. I tried the ff code but it gave me an error:
string value = dgOutput.CurrentCell.Value.ToString();
Please help.

What was the error?
Maybe check to see if the currentcell value is null?
string value;
if(dgOutput.CurrentCell.Value == null)
{
value = "null";
}
else
{
value = dgOutput.CurrentCell.Value.ToString();
}
|
|
|
|
|
If you want to access a cell other than the currently selected
dgOutput.Rows[rowindex].Cells[columnindexORname]

Not sure if this is 100% the right place but...
A year ago i released and app using clickonce and a test certificate. I have just made a change and found that the certificate had expired, so i created a new one. Now none of the users can use the app (it trys to download the new version on startup) unless i uninstall and reinstall. This is not a good option as most of our users are on remote sites
How can I get round not having to reinstall it for everybody?

I'm not sure. I'd try posting this question at the MSDN forum for ClickOnce.

Not directly.
You would have to write code to read the contents of the word file then transfer it into the text box.
|
|
|
|
|
You can use Word Object model to get all the text from word document but it will be just plain text. You can use this control to display doc file: Word Control for .NET[^]

Hi Guys
I have a DatagridViewcomboBox column in DataGridView where i m using EditControlShowing on selection Changed but when i select the same combo twise EditControlShowing is not working means It is not unselecting the EditControlShowing
|
|
|
|
|
That's because you haven't change the row you are in. Thus you did not cause the SelectionChange event to fire.
|
|
|
|

NetworkInterface[] networkInterfaces = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface networkInterface in networkInterfaces)
{
Console.WriteLine(networkInterface.Description);
}
How can I get the IP address from each networkInterface ?
Thx...
|
|
|
|
|
You can try something like this:
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties props = adapter.GetIPProperties();
UnicastIPAddressInformation unicastAddress = props.UnicastAddresses.FirstOrDefault(address => address.PrefixOrigin == PrefixOrigin.Dhcp);
Console.WriteLine(unicastAddress.Address);
}

Hiya,
Dont kniow if anyone can help - but worth a shot. I am writing an app that takes in 3 values from 3 columns in a CSV (account number, start date, end date). The code i have at the mo only reads 1 column at a time, and i am not too sure how i can read the 3 values and pass them to the stored proc to get processed. The proc takes the values and processes them line by line. At the moment it reads all the column values and inserts it for accounts, date1a, and date2a, whereas i actually only need column 1 for accounts, column 2 for date1a, and column 3 for date2a. I would appreciate any feedback to get a solution as google is not my friend right now  .
So far my code looks like this:
private void btnImport_Click(object sender, EventArgs e)
{
try
{
lblShowDetails.Text = "Importing accounts...";
this.Refresh();
DataSet ds = new DataSet();
if (ofd.ShowDialog() == DialogResult.OK)
{
FileStream fs = new FileStream(ofd.FileName, FileMode.Open);
StreamReader s = new StreamReader(fs);
StringBuilder sb = new StringBuilder();
while (s.Peek() >=0)
{
sb.Append("'" + s.ReadLine() + "',");
}
s.Close();
this.Cursor = Cursors.WaitCursor;
lblShowDetails.Text = "Retrieving data from the store...";
this.Refresh();
string accounts = sb.ToString().TrimEnd(",".ToCharArray());
string date1a = sb.ToString().TrimEnd(",".ToCharArray());
string date2a = sb.ToString().TrimEnd(",".ToCharArray());
try
{
ds.Tables.Clear();
if (sCustomer == "Customer1")
{
SqlDataAdapter da = new SqlDataAdapter("storedprocName", con);
da.SelectCommand.CommandTimeout = 0;
da.SelectCommand.CommandType = CommandType.StoredProcedure;
da.SelectCommand.Parameters.Add("@accounts", SqlDbType.VarChar);
da.SelectCommand.Parameters.Add("@date1", SqlDbType.DateTime);
da.SelectCommand.Parameters.Add("@date1", SqlDbType.DateTime);
da.Fill(ds, "xxx");
grdShowStats.DataSource = ds;
grdShowStats.DataMember = "xxx";
lblShowDetails.Text = "Done with Stats Enquiry...Waiting for next command";
