# V580\. Suspicious explicit type casting\. Consider inspecting the expression\.

The analyzer detected an odd explicit type conversion\. It may be either an error or a potential error\. 

Consider this sample:

```cpp
DWORD errCode = 0;
void* dwErrParams[MAX_MESSAGE_PARAMS];
dwErrParams[0] = *((void**)&errCode);
```

The code contains a 64\-bit error\. The 'DWORD' type is cast to 'void \*' type\. This code works incorrectly in 64\-bit systems where the pointer's size does not coincide with the size of the DWORD type\. This is the correct code:

```cpp
DWORD_PTR errCode = 0;
void* dwErrParams[MAX_MESSAGE_PARAMS];
dwErrParams[0] = (void *)errCode;
```
