Add up all of your pdblCredit's and all of your pdblDebit's inside your loops. Then, after the loops are done, subtract the debits from the credits and you'll have your balance.

PartSQL = "select * from Part"<br />

SelectAllParts = dtPartItems<br />
End Function<br />
but i Got this Error:
i have made a succesfull connection to an
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
----
any clue for that???
note that the connection test test is succeded

Hi,
This is a security feature. As specified in the error you cannot connect to a remote server until such connections are enabled in the settings.
Look at the following link

Ramy,
your function doesnt show anything about defining the connection string.
This will contain the server name, username, password, etc.
Create an SqlConnection object, pass in a connection string.
<br />
Dim cnn as New SqlConnection()<br />
cnn.ConnectionString = "Server=myserver;Database=mydatabase;User ID=myUsername; Password=myPassword;Trusted_Connection=False"<br />
Then when you create sql commands, you can pass this object in.
<br />
dim cmd as new SqlCommand("SELECT * FROM Table1;", cnn)<br />
dim adapter as new SqlDataAdapter(cmd)<br />
dim result as new Datatable()<br />
adapter.Fill (result)<br />
Hope this helps
Mark

Sorry to make another post, but in addition to my last post, is there a way to adjust the volume for either a Sound Recording/Media Player control? Or is there a way to adjust the Windows volume?

With the windows media player control use
Player.settings.volume = IntegerValue
Have a look at the Windows Media Player SDK Technology Page[^] and download some documentation. It'll come in useful, believe me.

Hey,
I just read a previous post that said something about a Sound Recording control (see here).
Anyway, I was just wondering if what that control is called in Vb.Net 2005? Does anyone know?
And, how do you get a Media Player control without the controls (play, stop etc.) at the bottom? Like the one used in Coding 4 Fun's "Non Destructive Media Edits" article? (Sorry, Coding 4 Fun took that article down, so I cannot provide a link).
Thank you!

Add a media player control to your toolbox (as shown here[^]). Drag & drop the media player control to your form and set the uiMode property to none.

How can I use a VB 2005 app to send keystrokes or bits of information such as a cheat.
like this:
1. I Press button on form (when my game is running)
2. The application then sends a cheat code (godmode, ect)
3. the cheat happens ingame
in other words instead of typing the cheats in the console of the game, i just press a button on my app and it does it automaticcaly. (instead of doing the 'trainer way' and messing with the games memory address (wich doesnt always work))
... sounds pretty hard, sorry to bother you with this. 
|
|
|
|
|
But that would be cheating......
anyway try building a console app that waits for the particular key stroke.
then used the Sendkeys() function in VB.
|
|
|
|
|
Um... sorry to burst your bubble.. but thats is the point, to 'cheat'
I kinda know how to use the sendkey function but can someone give me an example of sending it to the game?
