1.跳出错误法 ===================================================
在主界面的implementation {$R *.dfm} 下放入以下代码：
在主界面的implementation {$R *.dfm} 下放入以下代码：
procedure PatchInt3;
var
NOP: Byte;
NTDLL: THandle;
BytesWritten: DWORD;
Address: Pointer;
begin
if Win32Platform <> VER_PLATFORM_WIN32_NT then
Exit;
NTDLL := GetModuleHandle('NTDLL.DLL');
if NTDLL = 0 then
Exit;
Address := GetProcAddress(NTDLL, 'DbgBreakPoint');
if Address = nil then
Exit;
try
if Char(Address^) <> #$CC then
Exit;
NOP := $90;
if WriteProcessMemory(GetCurrentProcess, Address, @NOP, 1, BytesWritten) and (BytesWritten = 1) then
FlushInstructionCache(GetCurrentProcess, Address, 1);
except // Do not panic if you see an EAccessViolation here, it is perfectly harmless!
on EAccessViolation do ;
else
raise;
end;
end;
然后在窗体的Create中调用 PatchInt3 ；或者在窗体代码的最后一个end.前加入一下代码即可以解决
//-------------------------------------------------------------- i
initialization
begin
PatchInt3; //防止关闭窗口时出现CPU: ntdll.DbgBreakPoint
end;

3.内存处理法(这个也是我单位出现的问题)==========================
方法：
将XE2的borlndmm.dll,rlink32.dll二个文件给复制到D:\delphi\Borland\Delphi7\Bin 中。
原因：
说是因为DLPHI7的内存管理没有XE2的好。
