I am fed up with having to stamp everything i print at work with the "COPY" stamp. I have been thinking about this for while now and i cant figure it out.
I would like to write a program that will append a little "CC" carbon copy image at the bottom of everything i print. Does anybody have any ideas? This seems like it would be beneficial to a lot of people has anyone heard of something like this before being done?
Any kind of help is appreciated.
Thanks a lot
Cory

This is already done in the HP printer drivers, called watermarking.
Other than that, you will find this a very difficult task if you wanted to append this yourself using a kind of print monitor.

Hello all, I am working with VB.Net going to an Access database. I am working with the version of Crystal that ships with VS.Net 2005 and I am trying to design a report. I have an MR number as the grouping (because I have it in all of my tables that I read). But when I preview it from within Crystal (not running my code) I get mutiple copies of the same record showing on the page.
Does anyone have any idea what could cause this? Thanks for an input you can give me!!

Multiple copies of the same record in the report would mean that your SQL queries are returning those multiple copies because of some flaw in your SQL or table design.
Without seeing your table design and relationships and you SQL, it's impossible to tell you where else to look.

Thanks Dave, I mean to come post out here the I found the problem. It was with the linking of the tables. There must have been something wrong becaue I removed the links and then recreated the exact same links and this time it works. I am sure I had something wrong with them but I still don't know what it was. Thanks for you reply!!! You are always a great help!

Hi, I get the following error message when I run my application in the browser.
"Invalid cast from System.String to System.Byte[ ]"
I have changed cmdInsert.Parameters.Add("@docContent",OdbcType.Text) to cmdInsert.Parameters. Add("@docContent",OdbcType.Binary) like someone had suggested, but it still does not work. I have checked other variables for type mismatch but didn't find any. If you see anything at all wrong with my code please point it out. I would really be grateful if you can show me what is causing VS2003 to throw the exception. Thank you in advance for your help. The following are my code and database to help you better understand my situation.

On what line does this exception show up?

It shows up on line 92 where it says cmdInsert.ExecuteNonQuery(). Thank you so much for responding. I just don't know what else to do.

OK, this usually means you have mismatched one of your parameters. But, the code sample that you gave is NOT what you have running. This code wouldn't even compile, let alone run! Next time, COPY AND PASTE your code, do NOT retype what you THINK it is! How can I tell? The property name is Value, not "Values".
cmdInsert.Parameters.Add("@docID",OdbcType.int,30)
cmdInsert.Parameters["@docID"].Values =""
cmdInsert.Parameters.Add("@docDate", OdbcType.TimeStame,14)
cmdInsert.Parameters["@docDate"].Values = DateTime.Now.ToShortDateString()
cmdInsert.Parameters.Add("@docTitle", OdbcType.Varchar,30 )
cmdInsert.Parameters["@docTitle"].Values = txtFileTitle.Text
cmdInsert.Parameters.Add("@docType", OdbcType.Varchar,30)
cmdInsert.Parameters["@docType"].Values =StrFileType
cmdInsert.Parameters.Add("@docContent",OdbcType.Binary)
cmdInsert.Parameters["@docContent"].Values =arrFile
I can see several problems with creating the parameter objects. In the overload of Add that you're using, you're supplying a parameter name, an ODBCType, and a size for that type. You do NOT have to specify a size for basic types like ODBCType.Int because the size is always constant. For Text and Binary types, you do specify a size. So, changing the code a bit:
' Int's are always 4 bytes long, not 30.
cmdInsert.Parameters.Add("@docID",OdbcType.int).Value = String.Empty
' This is where your error occured. You used the TimeStamp type instead of
' Date. TimeStamp requires an array of bytes and you supplied a string of characters.
cmdInsert.Parameters.Add("@docDate", OdbcType.Date).Value = DateTime.Now
' This is a disaster waiting to happen! You don't do any validation of user input
' before you plug what the user typed directly into an SQL parmater! VERY BAD IDEA!
cmdInsert.Parameters.Add("@docTitle", OdbcType.Varchar, 30).Value = txtFileTitle.Text
' So far, this one looks good. Assuming, of course, that 30 is the
' actual size of the field in your database!
cmdInsert.Parameters.Add("@docType", OdbcType.Varchar, 30).Value = StrFileType
' I'd be willing to bet that this OdbcType doesn't match the field type in your database.
cmdInsert.Parameters.Add("@docContent",OdbcType.Binary, size is missing!).Value = arrFile

Thank you so much, you solved my problem. What you had said about the cause of the problem is exactly right, it works. I have a question however about what you said about Int always being 4 byte. I have seen people use 11 as the size of the Int type. Would you please explain? Also if I wanted to use a blob what would a good size be for it? Thank you so much for your help.

It doesn't matter what they put for the size, an Int is a 32-bit value, 4 bytes. Whatever they put will simply be ignored.
You don't put a size for a blob in MySql.

i am using two queries in the stored procedure.
first is the insert statement and then select statement
the stored procedure is
CREATE PROCEDURE [dbo].[AdminValidation] <br />
@uname as varchar(10),<br />
@pword as varchar(10)<br />
as<br />
insert into admin(u_name,p_word)values(@uname,@pword)<br />
select * from admin<br />
GO
Is it right?
|
|
|
|
|
I haven't done it in a stored procedure before, but the syntax seems to be ok.
Except not having an apostrophe ( ' ) around the @uname and @pword fields may give you trouble.
ie.
insert into admin(u_name,p_word)values('@uname','@pword')
select * from admin
GO
for any values that aren't numbers...you need the apostrophes around them to the best of my knowledge. Hope that helps a bit.

|

I agree the syntax seems fine.

The apostrophe is not required

Is that just for inside a stored structure? Just so I know.

If your have defined the variable/parameter as a text type field, e.g. varchar, nvarchar etc. then SQL Server knows it is a text value and will handle the value accordingly. So this would apply to stored procedures and functions.

oh I see, thanks man. Ya, normally I define them as strings, which makes sense now.

Does it work?

Add set nocount on to prevent the insert from returning a result.
create procedure AdminValidation
@UName varchar(10),
@PWord varchar(10)
as
set nocount on
insert into admin (u_name, p_word)
values (@UName, @PWord)
select u_name, p_word
from admin
Avoid using * in a select. Specify the fields that you want returned, that way the result of existing queries doesn't change just because you add a field to the table.

In a form in MS Access, I'm going to have numerous checkboxes...that when clicked on, populate a text body. Each checkbox points to a table that contains numerous paragraphs. So ideally, when each box is checked, its corresponding paragraph populates a text body. After all of the desired boxes are checked, the text body should have numerous paragraphs inside it. I want to be able to export this text body to a Word document, and save it as a specified file name. What would be the best way to go about this? I have a pretty good idea how to populate the text body using the database, but am alittle befuddled on how to export the data to Word. Thanks.

i was using stoed procedure and getting the following eror.
invalid object name adminvalidation
the code is as follows
Dim con As New SqlConnection(connectionstring)
con.Open()
Dim cmd As New SqlCommand("AdminValidation", con)
cmd.CommandType = Data.CommandType.StoredProcedure
cmd.Parameters.Add("@uname", Data.SqlDbType.VarChar).Value = TextBox1.Text
cmd.Parameters.Add("@pword", Data.SqlDbType.VarChar).Value = TextBox2.Text
cmd.ExecuteNonQuery()
adminvalidation is stored procedure name.
i have gone though This Article But in vain
