我试图在VB6中读取一个用C ++创建的二进制文件,反之亦然。
是否有任何数据类型转换我不得不担心从C ++转到VB6,反之亦然?
VB6布尔数据类型的C ++中的等价类型是什么?
这是我的C ++结构:
struct FooBarFileC
{
long int foo;
int bar;
};
这是我在VB6中输入的类型:
Public Type FooBarFileVB
foo As Long
bar As Integer
End Type
我在vb6中读取二进制文件的代码:
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
我在c ++中读取二进制文件的代码:
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中编写二进制文件的代码
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
我在C ++中编写二进制文件的代码
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));
