Database connection...

I have this code which should connect to a MS Access database and output the string values of "table´".. Well see for yourself :)

Code:

---

#include <stdio.h>
#include "E:\Program Files\Microsoft Visual Studio\VC98\mfc\SRC\stdafx.h"
#import "c:\program files\common files\system\ado\msado15.dll" rename("EOF", "EOFile")
struct StartOLEProcess {
StartOLEProcess() {
::CoInitialize(NULL);
}
~StartOLEProcess() {
::CoUninitialize();
}
} _start_StartOLEProcess;
int main() {
ADODB::_ConnectionPtr Con = NULL;
ADODB::_RecordsetPtr RecSet = NULL;
ADODB::FieldPtr pStrings;
 
_variant_t vStrings;
char sStrings[150];
HRESULT hr = S_OK;
VARIANT *RecordsAffected = NULL;
hr = Con.CreateInstance(__uuidof(ADODB::Connection));
printf("\nCreateInstance result=%d uuidof=%d\n", hr, __uuidof(ADODB::Connection));
printf("\nConnection object created.");
 
Con->Open("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\\database.mdb", "", "password", 0);
 
printf("\nConnection opened...");
RecSet = Con->Execute("SELECT * FROM strings", RecordsAffected, 1);
printf("\nSQL statement processed");
 
pStrings = RecSet->Fields->GetItem(Table);
printf("\nGetting data now...\n");
 
while(!RecSet->EOFile) {
vStrings.Clear();
vStrings = pQuestions->Value;
WideCharToMultiByte(CP_ACP, 0, vStrings.bstrVal, -1, sStrings, sizeof(sStrings), NULL, NULL);
printf("\n%s", sStrings);
RecSet->MoveNext();
}
printf("\n\nEnd of data..");
RecSet->Close();
RecSet = NULL;
printf("\nClosed and removed recordset object.");
Con->Close();
Con = NULL;
printf("\nClosed and removed connection object.");
return 0;
}

I can compile it okey, but with one warning:

Code:

---

Compiling...
main.cpp
d:\c++\database\debug\msado15.tlh(409) : warning C4146: unary minus operator applied to unsigned type, result still unsigned
Linking...
database.exe - 0 error(s), 1 warning(s)

---

so it compiles okey, and then when I try to run the program, the following output comes:

Code:

---

D:\C++\database\Debug>database.exe
CreateInstance result=0 uuidof=1300
Connection object created.
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Does somebody have a solution to my problem? :)

Thx in advance :D

I wish I could help pal, but that's just beyond me.

As a matter of fact, I'm a newbie to C/C++/C# programming.

That's okey :)

I'll get better, practice makes better ;)

But if any of you have a solution to my problem or any kind of help.. Just write please :D

Thx in advance :D
