Hey All
I am Stuck in a problem
I have an application that generates the Barcode
When I am printing that with the laser printer , Then That printed barcode is readble through the Scanner
But when I am printing it with the Label Printer(USed to print small badge cards, Address labels etc.) then that printed barcode (printed by label printer) is not readable by the barcode scanner
Can you give me the direction Why is it so.
Thanks for this help

Does it look different to the human eye? (stretched, etc.)
If not then your ink may not be compatible - i.e. the scanner has a single light wavelength and maybe the difference between bars and spaces in your ink in that wavelength is not sufficient.

Thanks for this prompt reply(really your answer is urgent for me)
I can't understand what is problem
That Printer also has a software that also generates sample Barcodes
& those printed barcodes (By label printer) are readable by that scanner
But the barcodes generated by my application & printed by label printer is not readable by that scanner.
But the barcodes generated by my application & printed by Laser printer is readable by that scanner.
That's why I am not getting the actual problem
what it is????
thanks & regards

If your barcode is getting streched left and right (I'm assuming a Code 39 or 128 barcode or something similar here) at all, then it won't read properly. Print a sample barcode on the printer that prints the working barcode and on the card printer (exact same barcode!) and measure the two. The length of the barcode should match exactly. If not, there's your problem.

 Yes I am using the Code 128 B BarCode symbology .
And also ,The Barcode printed by Label printer are somewhat different from the barcode printed by the laser printer.
That's why my scanner reads the barcode printed by the laser printer
but can't read the barcode printed by the label printer.
Now , I can't understand with what the exact problem is :
1. with barcode
2. With Label printer.
3. or Sacnner
Although all three are working properly individually.
Plz repy me as soon as possible for You
Thanks a bunch in advance.

There's your problem, although you don't say what's different about it. Because of this, no-one can really help you with anything.

4. Doing your own homework?
I dont think anyone minds helping people out with homework, but simply copying and pasting the assignment into a forum does not really constitute learning.

i find it shocking that they are still using MS Access for homework though. I barely remember when I last connected to an Access backend.

Hello! 
How could I scale all the images under one specific directory according to my (Width = 433 x Height = 566) white image template? Moreover, I should be resizing all the images according to aspect ratio.
If you help me to figure out, I would really apreciate it!
Thank You.

what's that crap ????
if you cannot answer a question, don't spam the forum, especially when it is your second message on the forum, and when the 1st one was not that better... 
people on CodeProject help because they want to ; no one owe nothing to anyone here, so if you're not satisfied, get out of here.

For a what?? An interview? You want source code sent to you so you can answer question about it during an interview?
Guy, if you can't write simple algorithm like this yourself, don't even bother going to the interview! You'll embarass yourself.

The problem is how to make use of relation between tables when I try to use parametrized query on the master table.
The code is like this:
1. Created data adapters
SqlDataAdapter1 - for first table, eg. PurchaseOrders with primary key PONum
SqlDataAdapter2 - for second table, eg. PurchaseOrderItems with primary key of two fields PONum<->POItemNum
2. Created data set
DataSet11 - for two related tables (one-to-many relation), joined by the key PONum
3. Filled the data set of data grid
SqlDataAdapter1.Fill(Me.DataSet11)<br />
SqlDataAdapter2.Fill(Me.DataSet11)
Then when I do not use the parametrized query the filling is done without errors. But when I modify SQL command of the SqlDataAdapter1 to use WHERE clause with parameter (eg. PO date) I get the error message. It cannot enforce constraints.
How to overcome this problem?

Private Sub Command6_Click()<br />
Dim strSQL As String<br />
Dim conn As ADODB.Connection<br />
Dim rs As ADODB.Recordset<br />
<br />
Set conn = New ADODB.Connection<br />
Set rs = New ADODB.Recordset<br />
<br />
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\User\Desktop\IS\ISDB.mdb; Persist Security Info=False"<br />
<br />
conn.Mode = adModeRead<br />
conn.Open<br />
<br />
strSQL = "SELECT MAX(inventno) FROM IncomingStk WHERE ProductCode= '"&code.Text&"'"<br />
<br />
rs.Open (strSQL), conn<br />
conn.Close<br />
DataGrid1.Text = rs(0).Value<br />
<br />
Set rs = Nothing<br />
Set conn = Nothing<br />
<br />
End Sub

Does the database table for ProductCode define that field as an int. if so, remove the single quote marks from you sql entry.
like:
strSQL = "SELECT MAX(inventno) FROM IncomingStk WHERE ProductCode =" & code.Text
also the way the your getting the value rs(0).value is not valid.
Should be
label.text = rs.Tables(0).Rows(0)(0).ToString().
This produces the value of row 1 col 1.

Naw, this is vb6, rs(0).value is the equivalent of saying
rs.fields(0).value
