C++ dll loadlibrary issue

Hello all. Does anyone know if there are compatibility issues with different version of C++ dll like one is created in VC 6.0 and another one in VC.NET? Because as I tried to load a dll in .NET it said "Unable to load DLL" but when I tried to create one C++ dll myself in VC.NET, it has no problem. Any idea? Sample code as below.

Visual C++.NET
short myFunction(char *value1, char *value2)
{
typedef short(CALLBACK* LFUNC)(char*,char*);
HMODULE hMod = NULL;
hMod = LoadLibrary("mylibrary.dll");
if (hMod == NULL) // It always run here
{
return 0;
}
LFUNC = (LFUNC)GetProcAddress(hMod ,"compareString");

if(!LFUNC)
{
return 0;
}
return 1;
}

VB.NET
Private Declare Function Score Lib "mylibrary" Alias "myFunction" (ByVal sValue1 As String, ByVal sValue2 As String) As Short

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
MsgBox(Score("string1", "string2")) // Error message "Unable to load DLL"
End Sub
