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.

The key words in your question are "Active Directory", "Create User", and "VB.NET". Let's see what happens when you type them into Google. Click[^]

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

And does the stored procedure actually exist in the database to which you've connected?

Can I or how can I populate a TreeView control using records in two table? Let say Parent Nodes comes from Table1 and each Parent Node has a child comming from Table2.
+--- Record 1 from Table 1
| |
| + Child 1 from Table 2 with reference to Record 1 in Table 1
| |
| + Child 2 from Table 2 with reference to Record 1 in Table 1
|
+--- Record 2 from Table 1
| |
| + Child 1 from Table 2 with reference to Record 2 in Table 1
|
+--- Record 3 from Table 1
| |
| + Child 1 from Table 2 with reference to Record 3 in Table 1
| |
| + Child 2 from Table 2 with reference to Record 3 in Table 1
| |
| + Child 3 from Table 2 with reference to Record 3 in Table 1
|
+--- Record 4 from Table 1
|
+ Child 1 from Table 2 with reference to Record 4 in Table 1
|
+ Child 2 from Table 2 with reference to Record 4 in Table 1
Hope that one will clear my question.
Thanks in advance.

What's the meaning of
Child 1 from Table 2 with reference to Record 1 in Table
|
|
|
|
|
Sorry for that. what i mean is "Child 1" came from Table 2 and had a reference (let say an ID) from a "Record 1" in Table 1. which means all child node are came from Table 2 and all parent node are came from table 1. just like in table/drawing i included in my post.
+--- Record 1 from Table 1 (TABLE 1 ID = '001')
| |
| + Child 1 from Table 2 with reference to Record 1 in Table 1 (TABLE 2 ID = '001')
| |
| + Child 2 from Table 2 with reference to Record 1 in Table 1 (TABLE 2 ID = '001')
|
|+--- Record 2 from Table 1 (TABLE 1 ID = '002')
| |
| + Child 1 from Table 2 with reference to Record 2 in Table 1 (TABLE 2 ID = '002')
|
|+--- Record 3 from Table 1 (TABLE 1 ID = '003')
| |
| + Child 1 from Table 2 with reference to Record 3 in Table 1 (TABLE 2 ID = '003')
| |
| + Child 2 from Table 2 with reference to Record 3 in Table 1 (TABLE 2 ID = '003')
| |
| + Child 3 from Table 2 with reference to Record 3 in Table 1 (TABLE 2 ID = '003')
|
|+--- Record 4 from Table 1 (TABLE 1 ID = '003')
|
| + Child 1 from Table 2 with reference to Record 4 in Table 1 (TABLE 2 ID = '003')
| + Child 2 from Table 2 with reference to Record 4 in Table 1 (TABLE 2 ID = '003')
as you can see, in Table 1 there are 3 records and Table 2 have 3 record in it. and for each record in Table 1 have a corresponding child (link record / relation to) in Table 2
anyway, thanks for the reply.

Hi,
I am using VB.NET 1.1 and I am having difficulty in finding a starting point in my array. My array is filled with Product objects. Lets say I want to start at row 301 and display all the products till row 600, how do I do this?
I have the following, but I don't know what to do further:
ByRef productArray As ArrayList (this is a parameter to this function.
Dim p As New Product
Dim i As Integer
For i = intStart To intEnd
For Each p In productArray
Response.Write("SKU: " & p.ID)
Next
Next
Please can someone help me??
Regards
ma se

For i = 301 To 600
p = productArray(i)
Response.Write("SKU: " & p.ID)
Next

Thanks Colin,
I was wondering if the same could be done for a SQLDataReader, using .NET 1.1. I have all the records in a datareader, and I am supposed to read in 300 records at a time. Depending on the page number. Page 1 should display records 1 to 300, page 2 should display records 301 to 600.
After populating the data reader, is it possible to start reading from a certain record?
Thanks
ma se

No a data reader cannot be navigated in a random access way. You need to read in the first 300 rows and discard them. You would be better filtering that out int he SQL query you sent in the first place.
