DLL裡，有拉TDataModule
裡面有
TClientDataSet *cdstemp1;
TSocketConnection *SocketConnection1;
TSimpleObjectBroker *SimpleObjectBroker1;

DLL 內有兩個 FUNCTION:
long __declspec(dllexport) __stdcall VCType_count(int m,int n)
{
long sum= 0;
for (m;m<=n;m )
{
sum =m;
}
return sum;
}
char* __declspec(dllexport) __stdcall VCType_GetKPNO(char* m)
{
int iIndex,iServerCount;
TdmSA *dmSA;
dmSA-> SocketConnection1->ServerGUID = "{ACFFAEFA-AEA2-440D-8AA1-DBC972DC04B2}"; // 在執行到出錯
}

Step by step 執行，發現 dmSA是 NULL。
後來改成在 function裡宣告
char* __declspec(dllexport) __stdcall VCType_GetKPNO(char* m)
{
int iIndex,iServerCount;

TClientDataSet *cdstemp2;
TSocketConnection *SocketConnection2;
TSimpleObjectBroker *SimpleObjectBroker2;
SocketConnection2->ServerGUID = "{ACFFAEFA-AEA2-440D-8AA1-DBC972DC04B2}"; // 在執行到出錯
}

錯誤訊息為:
'Access violation at address 40A234B6 in module 'dsnapcon60.bpl'

請問是哪沒寫好?

沒有 new
