I have created an excel sheet by executing a query on an external database using MS Query. Now I want the data that I have changed in the sheet to be updated back into the database from where it actually came. Is this possible? Do VB/VBScript provide any way of doing this?

I would like to know if the find method is the best if i want to open a field which the name is given by the user of my dlgbox application. For example, if the user write "1Y" in a edit box, my application will have to open the "1Y" field to catch value in it. So, do i have to use Find?
thanks in advance

Depends.
For example if the user write the EXACT text is better and more Quickly to use the command Seek, because this use the index, (you need that the field to be an index) But if the user write the no exact string how part to the string, in this case is better to use the Find.
Other solution is make a query.
Cheers!!!

Is there a performance hit if I encrypt all my database stored procedures?

Friends,
I'm calling an ActiveX DLL I wrote in VB from VC++. In the VB, I'm using the VB data environment to do a parameterized insert. Everything is OK until I get a duplicate key. As soon as the DataEnvironment.Commands(1).Execute statement runs, VB immeadiately returns to the C++ caller; the hResult is 0x800A0CC1, which doesn't make any sense being that the previous 812 insert suceeded. What I'm trying to do is trap the error on the VB side (using on error goto) so I can log it prior to returning to the caller. But, the error routine never runs due to the immeadiate return.
Any help will be much appriciated!
Thanks,

Can anyone suggest a report tool, add-in or something that I can use in my C++ project that tracks some basic usage data. Do most developers roll their own when they need to provide 10 or so, simple reports to screen and printer?
Any ideas would be appriciated.

hi,
Does anybody know how to use SQLXML Type Library in Visual C++ programs...
I need it to do some XML-data retrieving from SQL server 7.0.Or if there is another way to use SQL Server 7.0's XML features through ADO,please let me know...

I've got my application ready and it is running perfect under my developing computer (win95), but on an other machine (winNT) it doesn't start at all!!! No error-message is shown!
I think the proplem has to do with the control "Microsoft ADO Data Control, version 6.0 (OLEDB).lnk"
It is a matter of different paths?
"c:\windows\system\msadodc.ocx" on w95 and
"c:\winnt\system32\msadodc.ocx" on NT ?
I already use the MFC as a static lib. ADO 2.5 is installed on both computers.
Please help me!

Try to load dynamically the component... The #import <filename> is almost always a bad idea.
LoadTypeLibrary, CoCreateInstance, even old LoadLibrary can help.
Or it can be a different version control that has some methods on 95 and other on NT. Trying to call the method "7" when the interface implements only "6"...
By the way, application doesn't tell nothing? No crash, no "Debug", nothing? What does it mean "doesn't start at all"?

Sorry, I was not precise enough.
I didn't use the #import, I used "Project | add | Controls | Registred Active-X controls"...
(sth like that, I'm using a german visual studio)
I dragged the control with the mouse to a dialog in the dialog-editor ( and a MS-Data Grid etc )
"Nothing" means, nothing happens if i double click on the Icon in Win Explorer. Just as it wasn't there.
To Debug, i would have to install Visual sudio to the NT system. But I wanted to avoid it, cause it is always a matter: running on the development-computer is successfull, running on an other system fails:
On another NT System with Visual Studio, the application started, the starting querie succeded, but the user-queries failed (access error).
?
Thanks for your answer.

Hi
I tried to make my CRecordset derived class using a dynaset instead of a snapshot, and suddenly the recordset object was readonly. Why? How can I fix it?
I'm letting the CRecordset-derived object manage my CDatabase object, and uses only default open and construction parameters.

I have a need to replicate and synchronize an .mdb file in VC++ 6.0. I see that the JRO contains CreateReplica() and Synchronize() methods, these are precisely what I need to do. What I need to know is how to create the Replica object, I've seen reference to IReplica in the msjro.tlb file but I'm not sure what is the Replica equivalent of _ConnectionPtr. Once I know how to create the Replica object the rest should fall into place.

I've got a solution for my own question now, here it is.
I've found out how to create a replica of an Access .mdb file through VC++. Here's the code.
This code goes at the end of STDAFX.H
#import "C:\\program files\\common files\\system\\ado\\msado21.tlb" \
no_namespace \
rename("EOF", "adoEOF")
#import "C:\\program files\\common files\\system\\ado\\msjro.dll"
MSJRO.DLL uses a namespace JRO.
This code goes in a .CPP file
CoInitialize(NULL);
JRO::IReplicaPtr m_pReplica;
HRESULT hr0;
hr0 = m_pReplica.CreateInstance(__uuidof( JRO::Replica ) );
if(SUCCEEDED(hr0))
{
CString m_connectString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=D:\\JDOCS\\Data\\JDOCS.mdb";
m_pReplica->PutActiveConnection(_bstr_t(m_connectString));
CString m_repName = "D:\\JDOCS\\Data\\JDOCSRep2.mdb";
CString m_repDesc = "JDOCS Database Replica";
m_pReplica->CreateReplica(_bstr_t(m_repName), _bstr_t(m_repDesc), JRO::jrRepTypeFull, JRO::jrRepVisibilityGlobal, -1, JRO::jrRepUpdFull);
}
CoUninitialize();

Hi,
Is anybody knows the procedure to interact with an excel defined table from VC++?
thanks

I have been staring at this for 2 hours now and can't put my finger on the problem. Any comments would be helpful:
rs is a recordset that is already opened.
Platform is IIS 5 running on Windows 2000 Pro.
Database is SQL Server 2000
<br />
if rs.supports(adAddNew) and rs.supports(adUpdate) then<br />
rs.AddNew<br />
... update fields here<br />
rs.Update<br />
end if<br />
the problem is that I get an error telling me that the database can't be updated on the rs.AddNew line!

VC 6 or InterDev 6...
You can set both up to support debugging of Stored Procedures on SQL Server.
