convert to C#

[pcPirate]

Hi,

Can anyone help me to convert the following VB6 code into C#???

Declare Function SQLSetConnectOp tion Lib "ODBC32.DLL " (ByVal hDbc As Long,
ByVal iOption As Integer, ByVal lValue As Long) As Integer

Thanks in advance

Re: convert to C#

Here is some code that I used to import some Win32 functions from a Kernel32.Dll. I would suspect you could use the same code (obviously modified) to solve your problem:

internal class Kernel32
{
[DllImport("kern el32.dll", SetLastError=tr ue )]
public static extern int GetPrivateProfi leString( string szApplicationNa me,
string szKeyName, string szDefault, StringBuilder szReturnValue, int nSize, string szFilename );
[DllImport("kern el32.dll", SetLastError=tr ue )]
public static extern int GetPrivateProfi leSectionNames( byte[] lpszReturnBuffe r,
int nSize, string szFilename );
}

Maybe something like:
internal class ODBC32
{
[DllImport("kern el32.dll", SetLastError=tr ue )]
public static extern short SQLSetConnectOp tion ( int hDbc, short iOption, int lValue);
}

Don't forget that the data types are differenent between c/c++ and c#. C#int = c++long

Good Luck,
Kevin

Ug. I am not up on VB6, but I'll give it a shot:

public int SQLSetConnectOp tion( long hDbc, int iOption, long lValue )
{
...
return someInt;
}

I don't know what that "ODBC32.DLL " is for, but maybe you can work it in
there somehow. Also, I assumed the function was public, but you can change
it to protected or private if need be. Lastly, it looks like a forward
declaration of a function (a function prototype), but those aren't used in
C#, so you'll have to include the function's code with the function
declaration.

Good luck! :^)

using System.Runtime. InteropServices ;
[DllImport("ODBC 32.DLL")]
static extern int SQLSetConnectOp tion(UInt32 hDbc, int iOption, UInt32
lValue);
