u mean to make it like this ?
Dim MySqlCommand As SqlClient.SqlCommand = New SqlClient.SqlCommand

Right. But from the looks of things, your code needs to be cleaned up a bit more.
First of all, you're trying to execute the same SQL command twice. Was this the intent? (I don't think so.)
You're reading it once here...
MySqlDataAdapter.SelectCommand = New SqlClient.SqlCommand(sSQL,conSQL)
MySqlDataAdapter.Fill(MyDataSet)
And the other here...
MySqlCommand.ExecuteReader
I think you should get rid of the Adapter and DataSet and stick to MySqlCommand since I didn't see your code really using them anyways. Also, you need to dispose MySqlCommand and its DataReader once you're done using them. Not doing so would cause a database connection "leak" (for a database like Access, there are only a finite number of connections that can be made so this is important). Dispose them before you dispose the connection.
[edit]
Oops. I just noticed that you are closing the DataReader. You just need to dispose the MySqlCommand then.

Hi,
I need a hand. What I need to do is to read a word from a file (this I can do). Then I need to get my program to remove all duplicates from the word. After that I need to load that into a string of textboxes and then to add the alphabet starting from the last letter of the word.
e.g
1. Load the word mememe
2. Strip the duplicates so the final word would be me
3. Insert into textboxes and add alphabet e.g mefghijklnopqrstuvwxyzabcd
Thanks in advance
Stevelam

Steve...
You didn't specify in the specs whether or not the removal of duplicate letters, and the appending of the alphabet was to be case sensitive. The functions I wrote are both case sensitive.
Download this Visual Studio project from my web site.
http://www.2goodsoftware.com/snippets/duplicate letters.zip
When you run the project in VS, type any string into the textbox and click the button (neither control is appropriately named or initialized since the project is just a test bed). The modified string will be displayed in a message box.
There are two functions ... RemoveDupLetters and AddAlphabet. Copy both functions and paste them into a module (for global scope) in your project.
If I can be of further help, please let me know.

Thats great, thanks. The only problem is the fact that if I put in hello it gives me helopqrstuvwxyz but really I could do with helopqrstuvwxyzacbdfgijkmn
Thanks again for the quick responce.

I though the idea was to remove duplicate letters ... as in the second L in hello? Mayhe I missed something. Anyway, your welcome.

|

Sorrry I should have said that I needed the whole alphabet in the end, just that it started after the last letter and didnt have any duplicates. Hope you can help. Thanks once again.

Steve...
The plot thickens. To ensure that I fully understand what the specs are, please reply with the entire string you expect to get when you enter "hello".

Why don't you install the seperate CR version you have there ?

I doubt it. You should try it and see. I'd have expected the compiler to copy whatever you need into the bin dir though.

thanks
if i copy dll where should i copy those
|

It depends. Windows/System32 will work, but in theory, we're supposed to put dlls in the same dir as our app in .NET, which will also work.

Yes - how do you expect the program to work if you don't install all the required components on the client machine?
You'll need to check the licencing conditions for Crystal to see if what you want to do is kosha or if you need to buy additional licenses.

hi there,
i'm new to vb and i'm having problems formatting decimal values...
instead of displaying 0.26, my decimal points appear as commas(,) like this: 0,26
Can somebody please help me..

In some countries, they have a comma there, and dots for thousands, as in 1.000,00. Weird, I know, but in this multicultural world...
Speaking of which, your PC obviously believes it's in a locale where such a thing would be normal, and expected. If it's not, then check your timezone settings, etc.

Hi, well there are a few ways to get by...
dim decValue as Decimal
decvalue = format(yourvalue, "#.##0.00")
use this example to return the value as 0.25
for more decimal points, add more 0
the yourvalue, is the value you want to convert
hope this help

You're trying to get the letters to line up ? Try using tabs instead of spaces, perhaps ?
