问题描述
我在Windows7 64位的VS2008中创建了一个基于MFC对话框的应用程序.我放置了一些asm代码:
Hi,
I created a MFC dialog based app in VS2008 in Windows7 64bit. I placed some asm code:
void CMfcAsmTestDlg::OnBnClickedButton1()
{
char format[] = "%s %s\n";
char hello[] = "Hello";
char world[] = "world";
__asm
{
mov eax, offset world
push eax
mov eax, offset hello
push eax
mov eax, offset format
push eax
call printf
//clean up the stack so that main can exit cleanly
//use the unused register ebx to do the cleanup
pop ebx
pop ebx
pop ebx
}
}
我得到:错误C2415:操作数类型不正确.我使用"mov"一词的每一行都会发生这种情况.
我是否需要更改任何项目设置或包括任何文件?
I get: error C2415: improper operand type. This happens on each line I used the word ''mov''.
Do I need to change any project settings or include any file?
推荐答案
void OnBnClickedButton1()
{
char buff[256];
char format[] = "%s %s\n";
char hello[] = "Hello";
char world[] = "world";
unsigned int f = (unsigned int)format,
h = (unsigned int)hello,
w = (unsigned int)world,
b = (unsigned int)buff;
__asm
{
mov eax, w
push eax
mov eax, h
push eax
mov eax, f
push eax
mov eax, b
push eax
call sprintf
//clean up the stack so that main can exit cleanly
//use the unused register ebx to do the cleanup
pop ebx
pop ebx
pop ebx
pop ebx
}
}
问候.
