This type of thing is very common and has even happened to me a few times. It may be an uninitialized local variable being initialized to 0xccccccc and works great in Debug mode. In Release mode perhaps a check for NULL may be the cause of the problem. There are many other reasons why this could be occuring. You should probably begin by reading the article by Dr. Newcomer.

You could also spy on the SCSI bus and check if your commands are reaching the target.

1. Check the C++ head file include path are there in Project Property Setting.
2. Check the *.lib file added in Project Property Setting.
3. Clean the Build first.
4. Rebuild full project again.

What do you mean ? Your program will never call OnAutoProcessing on its own when you exit the program. It means you are doing it yourself and then the solution to your problem is simple: don't call OnAutoProcessing when you exit your program Smile | :)

Sorry, but your question is so vague that it's the only answer I can give. Where are you calling OnAutoProcessing ?

Member 31219 wrote:

By calling it before the end of the program maybe ? Roll eyes | :rolleyes:

As Cedric said - you asked this exact same question yesterday.

I replied to it already, asking for specific extra information: http://www.codeproject.com/Messages/3178744/Re-how-can-i-exit-the-program-entirely.aspx[^]

1/ You didn't work out that maybe you should give that information if you want help.

2/ You emailed me directly with the original question (which I don't actually mind), and didn't even give the answer(s) to my questions.

I can see it now...

Patient 31219: "Dr, I am ill, please help."
Dr Iain: "I will be happy to help, Patient 31219. Please tell me something about your symptoms."

Patient 31219: "Dr, I am ill, please help."
Dr Cedric: "I will be happy to help, Patient 31219. Please tell me something about your symptoms. Oh, didn't you see my colleague yesterday"
Patient 31219: Silence.

The next day:
Miss 31220: "Please, can you take my boyfriends body away. He died in his sleep, silently. He would have been my husband, but when I broke with chauvinistic convention and asked him to marry me, he never actually replied..."

Assuming it's possible, Program A has to make a parsable mile long command line, and Program B has to parse it...

The alternative of using a file is not only possible, it's *easier*. Some people get fixated on a route between two places, that even when a better route to the same destination is shown, they keep walking into the same brick wall.

Hash Look up Logic

Hi All

I tried hash Look up logic in C.I got unique hash value, but my look up table have only 5000 records so i need to reduce my hash value.

logic
h=h<<5+h+c

h=default value 3.

c=input character ascii value.

For Ex:
Input :Jon
Output:227018.

currently am getting hash value in billion or million.I want my hash value with in 5000.

I tried Mod function too..But it is giving duplicate value.So plz gimme solution for this....

Note:Input is string and output is number(for hash value).

Thanks,
Mohan.T

CRC is a non secured hashing function and it is widely used one.
For 5000 i think CRC 12 or CRC 13 as per ur need.

Just refer the below link

http://en.wikipedia.org/wiki/Cyclic_redundancy_check[^]

i am giving and example of for CRC 16 given below

const WORD CRC16BIT_TAB[8] =
{
0x0000, 0xCC01, 0xD801, 0x1400,
0xF001, 0x3C00, 0x2800, 0xE401,
};

unsigned int CRC16( const BYTE* pBuffer, const int nLength )
{
unsigned int ulCRCRet = 0;
unsigned int ulTempVal = 0;
int nIndex = 0;
for(nIndex = 0; nIndex < nLength; nIndex++, pBuffer++)
{
// lower 4 bits
ulTempVal = CRC16BIT_TAB[ulCRCRet & 0x000F];
ulCRCRet = (ulCRCRet >> 4) & 0x0FFF;
ulCRCRet = ulCRCRet ^ ulTempVal ^ CRC16BIT_TAB[*pBuffer & 0x000F];

// Upper 4 bits
ulTempVal = CRC16BIT_TAB[ulCRCRet & 0x000F];
ulCRCRet = (ulCRCRet >> 4) & 0x0FFF;
ulCRCRet = ulCRCRet ^ ulTempVal ^ CRC16BIT_TAB[(*pBuffer >> 4) & 0x000F];
}
return ulCRCRet;
}

int main(int argc, char* argv[])
{
BYTE data[] = { 'A', 'D', 'E', 'R', 'T', 'W', 'i', 'E', 'Y', 't' ,'h', 'e', 'm', 'r', 'T'};
unsigned short int ulCRCVal = 0;
ulCRCVal = CRC16(data, sizeof(data) / sizeof(data[0]));
std::cout << ulCRCVal << ::std::endl;
return 1;
}

I'm guessing you want a minimal perfect hash function[^]...

There's a tool[^] that will calculate perfect hash functions for you given a list of keys.

"I tried Mod function too..But it is giving duplicate value.So plz gimme solution for this...."

I think I see your problem. Hash functions typically WILL give duplicate values. This is called a collision. There are various ways of dealing with collisions.

The simplest is to simply go to the next-highest slot (mod 5000), and store your value there. When you're looking up a value, and the desired value isn't at the hash location, you go to the next slot because it probably collided with another value already at the hash location.

You keep going to the next slot until you either find the desired value, or you hit an empty slot, which means the value isn't in the hash table.

set dialog transparence but control not

add code in OnInitDialog

SetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE,GetWindowLong(this->GetSafeHwnd(),GWL_EXSTYLE)^0x80000);

HINSTANCE hInst = LoadLibrary(_T("User32.DLL"));
COLORREF color1= RGB(0,255,0);

if(hInst)
{
typedef BOOL (WINAPI *MYFUNC)(HWND,COLORREF,BYTE,DWORD);
MYFUNC fun = NULL;
//取得SetLayeredWindowAttributes函数指针
fun=(MYFUNC)GetProcAddress(hInst, "SetLayeredWindowAttributes");

if(fun)fun(this->GetSafeHwnd(),color1,160,2);

FreeLibrary(hInst);
}
can make dialog transparence .The control also become transparence too, how to do that i need transparence dialog and opacity control.
