Hey Leppie. The @RETURN_VALUE parameter is auto-created, as you guessed, by SQL Server when you Return something. For Example:
ALTER PROCEDURE uspIsValidUser
@UserName VarChar(20)
AS
BEGIN
IF (SELECT COUNT(*) FROM tblUsers WHERE UserName = @UserName) = 1
BEGIN
SELECT UserName, Address, City, State, ZipCode
FROM tblUsers
WHERE UserName = @UserName
RETURN True
END
ELSE
RETURN False
END
In your code, you can then check the value of @RETURN_VALUE value to see what was returned. It's possible to return datasets at the same time due to the fact that return VALUES are automatically stored in @RETURN_VALUE.

Interesting. You write an app to generate stored procs but still need to ask what @RETURN_VALUE is and what it's for.

I'm pretty new to the SQL world, so thats why I'm asking... I dont really every have had the need to use it (yeah, I know its a bit more effiecient, but I prefer to do what I know works).[edit]And the fact that VS.NET creates it automatically [/edit]
Can I ask you this? Did you even bother to read the article and download the project? Have you tried it perhaps on a database of your own and see the results?

I'm not quite interested in reading an article titled "SQL Stored Procedure Wrapper" written by someone who knows nothing about stored procedures.

Thats poor attitude! Who says I know nothing of SP's? YOU, because I dont know what @RETURN_VALUE does, and why it get auto generated by VS.NET. Why not try being a bit helpful, and less ignorant?
And please, being all knowing (as it appears), why not give me an example of the generated @RETURN_VALUE usage? MSDN sure doesnt prove to be helpful (in this aspect).

A client is in a bind because one of their contract developers ran off to London with the source code to an Access project.
From what they are telling me they have a directory with an MDB file, some EXEs and setup app. It creates a shortcut icon with a target like this C:\SPP05\MSARN200.EXE C:\SPP05\spp05.mdb /ini C:\WINDOWS\spp05.ini
The client tells me the file is compiled (have not got a hold of it yet) and I was wondering; Can you get into the VBA code as well as the actual database structure? They want some modifications. Does Access ever compile right down to an executable? Or is more of an interpreted type environment?
Sorry for the lack of info and thanks for any help.

Paul, from what I remember and what I just checked, most code should be contained inside a module(s) if it is strickly VBA which is in the Database itself for you to look at, however if they actually have an executable then it is more likely a VB app that is making ADO/DAO calls into that particular datbase. The modules inside Access themselves are meant to run within Access. Hope this helps.

If I set a password for my Access DB and I try to connect using CCommand, it won't work!
<br />
HRESULT hr;<br />
<br />
CDBPropSet dbinit(DBPROPSET_DBINIT);<br />
<br />
dbinit.AddProperty(DBPROP_AUTH_CACHE_AUTHINFO, true);<br />
dbinit.AddProperty(DBPROP_AUTH_ENCRYPT_PASSWORD, false);<br />
dbinit.AddProperty(DBPROP_AUTH_MASK_PASSWORD, false);<br />
dbinit.AddProperty(DBPROP_AUTH_PASSWORD, OLESTR("pwd"));<br />
dbinit.AddProperty(DBPROP_AUTH_USERID, OLESTR("Admin"));<br />
dbinit.AddProperty(DBPROP_INIT_DATASOURCE, m_sSource );<br />
dbinit.AddProperty(DBPROP_INIT_MODE, (long)19);<br />
dbinit.AddProperty(DBPROP_INIT_PROMPT, (short)4);<br />
dbinit.AddProperty(DBPROP_INIT_PROVIDERSTRING, OLESTR(""));<br />
dbinit.AddProperty(DBPROP_INIT_LCID, (long)1033);<br />
hr = m_db.Open(_T("Microsoft.Jet.OLEDB.4.0"), &dbinit);<br />
if (FAILED(hr))<br />
return hr;<br />
<br />
return m_session.Open(m_db);<br />
I used to do this a hundred times with ASP and password-protected DB with no problem. Why is it like that with CCommand?
Thanks!

You have to give the password and user in connection string.

You should set connection to something like this,I use this string in C# but I think it is the same in other places too:(in your 'open' function use this)
"Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:database Password=mypass;User ID=username;Persist Security Info =True;Data Source=myfile.mdb;Jet OLEDB:System Database=E:\\Documents and Settings\\Mazyprogrammer\\Recent.mdw";
Hope it helps.

Hi all,
I have a requirement to convert MS Access queries to Oracle queries.
In MS Access there are pre-defined functions called last, first and Int. I
need to know the oracle equivalent for the above mentioned functions. It
would be great help if u could explain the functions first, last and Int
with small examples.
Best Regards

I need to compare two identically structured tables to get the differences from one of the tables. Any ideas on the easiest/quickest way to do this?

hello @all,
i have an access data base and a dialogbased program.
to connect the program with the data base i used odbc.
then i add a new class in my project (CRecordset, name: CDatabase) and choose the table i want.
finally i want to register now something into my data base.
I make an object of the data base:
<br />
CDatabase db;<br />
db.Open();<br />
db.Edit();<br />
db.m_x=1;
db.Update();<br />
db.Close();<br />
i get the error in my program, that there is no current data record.
what´s wrong????
Thank you in advance.

I've tride search after a book about ADO with examples written in C++ but it seems to be impossible!?
Can you help? Is there any ADO books with examples written in C++ and not VBScript/VB?

I couldn't find one, but it's not hard to convert. That's WHY they write them in VB, because we C++ programmers can do the conversion and the average VB programmer would not cope converting C++ code to VB.

Is it really that easy?
I feel it's not because _variant_t has no similar type in VB? or?
But if the professional says it's possible.... it shold be possible in some way!
Thanks, then I'll buy ADO 2,6 by Wrox. I think that's the best one I've seen!

I thought the best one was the one from O Reilly, but I am partial to them. They actually have a chapter showing how stuff works in different languages, then the rest is in VB. Wrox books for me are fat with useless code listings.

VB has no types, does it ? VBScript doesn't.

I will check it out. I Like Wrox books but it's pretty true that you say "useless code listings". But I like when it is a little too mucj code that almost nothing!

Ooogh... okay... I don't know VB that much... I know VBScript has no types!

If you use the #import "C:\Program Files\Common Files\System\ADO\msado15.dll" method, then C++ use of ADO is almost as easy as using VB.
The ADO wrapper generated is very nice, with this you shouldn't have any problem converting VB code.

Hey Mike!
You scared the sh*t out of me! 
I thought you had a recomendation of a book about ADO in C++... I've already ordered that book from O´Reilly which Christian suggested me (Which is written in VB)! 
Promise me that you'll never do that again!
