Winspool.drv - set advanced printer properties

Can Winspool.drv be used to permanently set printer properties?

Or do you know of any third party libs that I can use?

You can use WinSpool.drv to do this. The documentation is here[^]. The only requirement is you must have a complete understanding of the Windows Printing subsystem in order to use it.

I was looking into this as a way to automatically setup the Microsoft Office Document Imaging printer. Like selecting .tif's and the default print folder.

I've run into several issues like this where you can just about reach it - but you gotta have a lot of time.

Thanks for the link anyway!

read paradox file(.DB)

I am writing an application in vb.net 2005 to read, update, and insert data to paradox database file(.db). When I try to connect I get this error: ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

Here is my code:

Dim connectionstring As String = "Driver={Microsoft Paradox Driver(*.db )};DriverID=538;Fil=Paradox 5.X;DefaultDir=C:\Data Feeds\;Dbq=C:\Data Feeds\;CollatingSequence=ASCII"<br />
<br />
        Dim querystring As String = "SELECT * FROM PriceBooks.DB"<br />
        Dim tableName As String = "PriceBooks.DB"<br />
<br />
        Dim dataSet As DataSet = New DataSet<br />
<br />
        Using connection As New Odbc.OdbcConnection(connectionstring)<br />
            Dim adapter As New OdbcDataAdapter()<br />
            adapter.SelectCommand = New OdbcCommand(querystring, connection)<br />
            Dim builder As OdbcCommandBuilder = New OdbcCommandBuilder(adapter)<br />
<br />
<br />
            connection.Open()<br />
            adapter.Fill(dataSet, tableName)<br />
<br />
            adapter.Update(dataSet, tableName)<br />
            Me.DataGridView1.DataSource = dataSet<br />
            Me.DataGridView1.DataMember = "PriceBooks.DB"<br />
        End Using

Any ideas on what the problem might be?

You might want to tell us on which line the error occurs and you also want to get rid of the ".db" after Pricebooks:

Dim querystring As String = "SELECT * FROM Pricebooks"

Perhaps the machine doesn't have the Paradox driver installed?

Adding drop shadows to controls

Ahmad Zaidi23-Jul-07 0:58

Hi,

I have made an irregularly shaped control to which I want to add a drop shadow (like the one XP menus and the mouse cursor have). Is there any way to do this?

Thanks,
Ahmad

Re: Adding drop shadows to controls

one way to do this (a bit clumsy dough) is just to duplicate the control put its color a bit darker (or total dark depending on what you want) and then put it behind the other control.

there's probably a beter way to do this but this is one way

perhaps an other way would be to create a usercontrol and draw the whole thing yourself
(put the region of the uc to the irregularly shaped path)
down side with this is that when users click the drop shadow it will fire the click event of the uc (but it is a bit less clumpsy then methode 1)

She wants the previous record of a given record by ID.

i.e. if you have rows

1
3
5
7

and the given row was 7, she wants row 5.

Hi Sonia

To get the previous record:

select * from MyTable where ID in (select max(ID) from MyTable where ID < 5)

For the next record:

select * from MyTable where ID in (select min(ID) from MyTable where ID > 5)

Neat code - You have bypassed using group by and used subqueries instead and I wonder if this is more expensive CPU-wise than group by?
Do you know if this is the case?
I realise using group by would create more code.

You always pass failure on the way to success.

andyharman23-Jul-07 5:52

Depending on the indexes available, SQL-Server would normally resolve the sub-query straight from an index. Then do a (probably clustered) index lookup to obtain the single resulting row.

How would you do this using a "group by" clause? I can't think of any way that would be as efficient as using a sub-query in the particular case.

Hats off to you I could not manage to code this with an aggregate query.

depending on wether or not your text file has the correct html format you could do this like so:

if the txt has the correct format just copy the file with the html extension

if not you'll need to create a new file (textwriter) insert the correct format
inbetween you read the original txt file and insert it into the new one (possible in a label or so) then save it with the html extension

hope this helps

hi i have created a main page with username and password (not a web page), i want to know how am i suppose to save this password and username in the database. so everytime i login, i need to type my password and username to enter the next page..
1. on the first time i login i dont need a password and username but once i'm login i need to set a password and username so i can use them the next time. is that possible?
2. can i know the coding to validate this pass and username..

pls help!!!

Re: username and password [modified]

Tom Deketelaere22-Jul-07 23:25

1. first check if the username is present in the database
if so go to 2.;P
if not insert a new record in db with username and password (make username unique value in db otherwise you might have problems)

2. this is depending on wether or not you want to encrypt the password
if not you just compare 2 strings (password is saved as a readable string in db)
if txtusername.text.tolower.equals(db.username.tolower) then
if txtpassword.text.tolower.equals(db.password.tolower) then
end if
end if

if you do want to use encrypted password its a bit more difficult but I have the code somewhere if you need it I'll look for it
just let me know

hope this helps
