VB6和VC++二進制文件讀取/寫入

Question

我想讀取VB6中創建的二進制文件，反之亦然。

是否有任何數據類型轉換我不必擔心從C++轉到VB6，反之亦然？

C++中用於VB6布爾型數據類型的等效類型是什麼？

這裏是我的C++結構：

struct FooBarFileC 
{ 
    long int foo; 
    int bar; 
}; 

這是我在VB6類型：

Public Type FooBarFileVB 
    foo As Long 
    bar As Integer  
End Type 

我在VB6讀二進制文件代碼：

Dim fooBarvb As FooBarFileVB 
Dim strOptionsFileName As String 
strOptionsFileName = "someFile.bin" 

If Dir(strOptionsFileName) <> "" Then 
    file_length = FileLen(strOptionsFileName) 
Else 
    file_length = 0 
End If 

fileNumber = FreeFile 

If (file_length <> 0) Then 
    Open strOptionsFileName For Binary Access Read Lock Read Write As #fileNumber 
    Get #fileNumber, , fooBarvb 
    Close #fileNumber 
End If 

foo = foobarvb.foo 
bar = foobarvb.bar 

我用C++讀取二進制文件的代碼：

long int foo; 
int bar; 
FooBarFileC cFooBar; 

ifstream fin("someFile.bin", ios::binary); 
fin.read((char*)&cFooBar, sizeof(cFooBar)); 
fin.close(); 

foo = cFooBar.foo; 
bar = cFooBar.bar; 

我在VB6

foobarvb.foo = foo 
foobarvb.bar = bar 

If Dir(strOptionsFileName) <> "" Then 
    file_length = FileLen(strOptionsFileName) 
Else 
    file_length = 0 
End If 

fileNumber = FreeFile 

If (file_length <> 0) Then 
    Open strOptionsFileName For Binary Access Write Lock Read Write As #fileNumber 
    Put #fileNumber, , fooBarvb 
    Close #fileNumber 
End If 

我的代碼編寫的二進制文件在C++

long int foo; 
int bar; 
FooBarFileC cFooBar; 

cFooBar.foo = foo; 
cFooBar.bar = bar; 

ofstream fout("someFile.bin", ios::binary); 
fout.write((char*)&cFooBar,sizeof(cFooBar));
