Hi,
I am developping application in C# with MSAccess databases and whenever I create an OLE DB Connection, something fails. When I select the Jet 4.0 Provider, I get a E_FAIL on the Select command in the wizard. When I use a OBDC connector to connect to an existing DSN, I get some sort of error saying that the data isnt compatible. What method should I use to connect a c# app with a MSAccess local db using the wizard in VS.NET or maybe there is a way to do this without using ODBC. Thanks

Hello.
I need a little help.
What is it about...
I have a project in Visual C++ in which im using ADO. So i import an ado dll like that :
#import "c:\Program Files\Common Files\system\ado\msado15.dll" no_namespace rename("EOF", "adoEOF")
its OK
But i need to use and AdoX
so in one help ( in MSDN ) i saw that code and i used in py project:
#import "c:\Program Files\Common Files\system\ado\msado15.dll"
#import "c:\Program Files\Common Files\system\ado\msadox.dll" no_namespace
Super, but it does not work:
--------------------Configuration: s - Win32 Debug--------------------
Compiling...
StdAfx.cpp
\my_source\s\debug\msado15.tlh(409) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
\my_source\s\debug\msado15.tlh(1317) : error C2629: unexpected 'short ('
\my_source\s\debug\msado15.tlh(1317) : error C2238: unexpected token(s) preceding ';'
\my_source\s\debug\msadox.tlh(1201) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
Error executing cl.exe.
s.exe - 2 error(s), 2 warning(s)
////////////////////////////////////
when i click on the error it goes to the source file on this line: VARIANT_BOOL EOF;
I tried various ways, to change places of the no_namespace rename("EOF", "adoEOF") è no_namespace
but there is no any result, just gives me other errors.
So if anyone knows how it would work ill be glad to tell me.
Thank you in advance.

I don't know Access, but it sounds like the user account that the server ASP process runs under does not have write permissions on the .mdb file.
Change, or get the server admin to change, the permissions on the .mdb file to allow write access for the IUSER_* or IWAM_* accounts (I forget which).
Hope that helps.

Okay.
I wanted to see if MSDE was cool and determined it was.
But I've got vs.net entp ed and figured i didn't need msde anymore.
I went to control panel and removed msde.
NOW, when i run the service manager, it says
"service unavailable" or something like that...
What do i do??? Are my databases toasted now?
If someone can give me a hand, I'd -reallllly- appreciate it..
Thanks.
Oops - forgot to say I'm on XP home edition with SqlServer 2000.

If you still have the .mdf (and .ldf, not sure if these are important) files, you should be able to reattach them to an existing database instance. Look up the sp_attach_db system stored proc. You could probably do this via Enterprise Manager too.
I'm not sure what the Service Control manager is complaining about. It may be looking for a particular SQL Server instance (machinename\instance).

MSDE is a limited Version of SQL Server and it is actually the same service called MSSQLSERVER
Check in Services Control Panel if there is a MSSQLSERVER service running and if it shows to correct path.
It can be that you will have to reinstall SQL Server

Hi everyone,
I am using the "Microsoft OLEDB provider for Microsoft Jet" through ADO and everything is going fairly well, except for the processing of provider errors....
The problem is that I can detect them ok, but I need to do specific things depending on which error occurs, which is obvious, however I am having a major hard time trying to find out what errors can be thrown by the provider.
Does anyone know where I can find a list of the error codes that can be issued by the above provider, the ones I have found (through trial and error) are:
// JET Error codes returned through ADO (Provider Errors)
0xDFBAF18A
An attempt to update a field with a zero-length string when the field does NOT support it
0xDFF8F252
Systax error in INSERT INTO statement
0xE004FBFC
Unrecognized database format
0xE0BBF3E4
Syntax error (missing operator) in query expression
0xF9BBF9BB
The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship.
I get these error codes consistantly, but do they look wrong to anyone ? I am suspicous as when I do a search for any of them on the internet, it comes up blank everytime.
regards,
Jonathan

Per MSDN:
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1.

Is this possible with SQL/Access? If so, how?
Thanks for your help!

I don't know about Access, but SQL Server 2000 lets you specify the collation for comparisons. For example, for a general case-sensitive / accent-sensitive search, try:
SELECT *
FROM TableName
WHERE Description = 'A Description'
COLLATE SQL_Latin1_General_CP1_CS_AS To get a list of available collations, execute:
SELECT * FROM ::fn_helpcollations()

Hello,
I have a problem that i cannot solve.
The problem shows up in XP, the code works fine in 98SE
Please if you know the answer help me
The code:
conITEMS.Open "Driver={Microsoft Visual FoxPro Driver};SourceType=DBF;SourceDb=" & "D:\work\old"
rsITEMS.CursorLocation = adUseClient
rsITEMS.Open "SELECT * FROM STOCK", conITEMS, adOpenStatic, adLockPessimistic
rsITEMS.MoveFirst
rsITEMS.Find ("number = '2004'")
This is where it fails with error = Run-time error '2147467259 (80004005)'
"data provider or other service returned an E_FAIL status"
Thank you in advance

Hi
It is probably because VFP Drivers are not included in MDAC 2.6 and above.
You can download this drivers from Microsoft Visual FoxPro page. Here is the link

Hi! I'm in a work with a webapplication...
I made my own Sqlwrapper class to handle all of my database access querys.(To make sql connection closeing simplier. Useing the same connection/thread etc.)
I close the connection at the end of the usage, but at the performance monitor of SQL server userconnections statistics seems to grow!
Maybe the datagrid.?
May datagrid reopen my connections, or keeps it alive, while i'm visiting the page?
i close it really.
i tried to close it, referenced itt null, called the GC.Collect().
not helped.
The unused connections are dieing later. at the SQL server enterprisemanager there are .Net SqlClient DataProvivider sleeping threads, awaiting for command (Wait type: not waiting!). I called all of the close connections! There isn't deadlocked state. Some cache??
Can you help me?

Hi!
I have a database project using MFC and ODBC. When we create a ODBC project, we obtain a CMyRecordView class derived from CRecordView. This class use a dialog template to represent data.
I want to use a CListCtrl to represent my data.
So in my class CMyRecordView.h I have declared
CListCtrl m_wndListCtrl;
In my CMyRecordView.cpp :
DDX_Control(pDX, IDC_LISTCTRL_VIEWDATA, m_wndListCtrl);
and :
void CMyRecordView::OnInitialUpdate()
{
m_wndListCtrl.InsertColumn(0,_T("Item"),LVCFMT_LEFT,100);
m_wndListCtrl.InsertColumn(1, _T("Value"),LVCFMT_LEFT, 100);
m_wndListCtrl.InsertColumn(2, _T("Time"), LVCFMT_LEFT, 100);
m_pSet = &GetDocument()->m_DataBaseManagerSet;
CRecordView::OnInitialUpdate();
}
In my dialog, my control style is set to VS_REPORT
The problem is that I dont see my columns.
I see a grey bar, but I dont see any text and I dont see any line break.
thanks for helping...
Everything's beautiful if you look at it long enough...

Hi All,
I'm trying to imlpement a helper .dll for managing some data on an Access DB using ADO. I found some sample code, that is working (sort of), but not too reliably. What I'm trying to figure out how to do is to populate some tables with new records, say 500+ at a time.
Basically, I open a recordset with the name of the table, then for each row, call AddNew, and set the values of the fields. After I'm done with all the rows, I call the Update method of the recordSet. Thing is, this works OK only if I do it kind of slow. I've got a Sleep(100) between each row, then I get all the data into my database. If I comment this out, I get nuthin'.
What's the deal? How would you do something like this:
struct Data
{
std::string Name;
double dWeight;
}
const Data arrData[] =
{
"Bob", 175.00,
"Tina", 130.00,
// lots more rows
};
Move all of this into an Access DB all at once.
Here's my actual code:
// To append a single row to the DB
HRESULT CHTDMBridge::AppendRow(/*const _bstr_t& bstrTable, */ValueMap& values)
{
// Must be connected
HRESULT hr;
if(m_pConnection == NULL) return E_FAIL;
if(m_pRecordSet == NULL) return E_FAIL;
// Going too fast for ACCESS??
// Sleep(100);
try
{
// Create a new record
hr = m_pRecordSet->AddNew();
if(FAILED(hr)) printf("\nOops!");
// For each field
ADO::FieldPtr pField;
_variant_t vField;
_variant_t vValue;
ValueMapIterator it;
for(it = values.begin(); it != values.end(); it++)
{
try
{
vField = (*it).first;
vValue = (*it).second;
// Set the value of the indicated fiels (it better be there)
m_pRecordSet->Fields->GetItem(vField)->Value = vValue;
}
catch(...)
{
printf("\nError updating fields in new record");
PrintProviderErrors(m_pConnection);
}
}
}
catch(_com_error e)
{
printf("\nError: %s, Desc: %s", e.ErrorMessage(), e.Description());
PrintProviderErrors(m_pConnection);
}
catch(...)
{
}
return S_OK;
}
// To append a lot of rows:
template<class _recordtype="">
void AppendRows(const char* szTableName, std::vector<_RecordType>& vct)
{
// Open the table
OpenTable(szTableName);
// For each record
std::vector<_RecordType>::iterator it;
ValueMap values;
_RecordType record;
for(it = vct.begin(); it != vct.end(); it++)
{
values = *it;
AppendRow(values);
}
// Update the database
HRESULT hr = m_pRecordSet->Update();
if(FAILED(hr)) printf("\nOops!");
m_pRecordSet->Close();
}
// To open the recordset to a given table
void OpenTable(const std::string& szTableName)
{
try
{
// Open the table
_variant_t vConnection = m_pConnection.GetInterfacePtr();
_bstr_t bstrTable = szTableName.c_str();
_variant_t vSource = bstrTable;
m_pRecordSet->Open(vSource, vConnection, ADO::adOpenForwardOnly, ADO::adLockPessimistic, ADO::adCmdTableDirect);
}
catch(_com_error e)
{
printf("\nCHTDMBridge::OpenTable(%s), Error: %s, Desc: %s", szTableName.c_str(), e.ErrorMessage(), e.Description());
PrintProviderErrors(m_pConnection);
}
catch(...)
{
}
}
Any help is appreciated.
