x32的LVM_GETITEMTEXT和C的x64

我一直试图让listview中的项目文本成为另一个过程.我在 CodeProject找到了一个很棒的教程.感谢这篇文章,我能够在x32上做到这一点.但是当尝试在x64上运行时,它会在调用SendMessage时崩溃我正在尝试访问的应用程序.在文章评论中,由于指针大小不同,人们有类似的问题.有人建议使用我不能使用的x64编译器.我需要我的程序在x32 / x64上运行.一个人建议：

I have the answer. The LVITEM
structure is wrong under 64-bit
systems. Pointers are 64-bit now,so
the text pointer has to be followed by
a dummy value,to offset the length
member correctly.

我认为这将是最好的解决方案,因为我可以用一个exe运行x32和x64.我只是不知道如何做他正在谈论的事情.我已经包含了目前适用于x32的代码.如果有人可以帮助我.那太棒了.

LVITEMLVITEM lvi,*_lvi;
char item[512];
char *_item;
unsigned long pid;
HANDLE process;

GetWindowThreadProcessId(procList,&pid);
process = OpenProcess(0x001f0fff,FALSE,pid);
_lvi = (LVITEM*)VirtualAllocEx(process,NULL,sizeof(LVITEM),0x1000,4);
_item = (char*)VirtualAllocEx(process,512,4);

lvi.cchTextMax = 512;
int r,c;
for (r = 0; r < rowCount; r++)
{
    for (c = 0; c < columnCount; c++)
    {
        lvi.iSubItem = c;
        lvi.pszText =_item;

        // Insert lvi into programs's memory
        WriteProcessMemory(process,_lvi,&lvi,NULL);
        // Have program write text to in its memory where we told it to
        SendMessage(procList,LVM_GETITEMTEXT,(WPARAM)r,(LPARAM)_lvi);
        // Get TVITEM back from programs
        ReadProcessMemory(process,_item,item,NULL);
     }
 }
 // Clean up the mess we made
 VirtualFreeEx(process,MEM_RELEASE);
 VirtualFreeEx(process,MEM_RELEASE);
 CloseHandle(process);
