There's another repost two threads below, where the OP wants a string with its length being 72K+ to be passed in as a command line arugment. Dead | X|

Thats really sad, that they dont read the msdn for any API since in the later discussed case, the maximum is only 32 k.

I saw that! Yikes...

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.

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.

Outlook Automation

Hi,
I am trying to get emails from outlook using outlook automation.
To access the MAPI function I have to import 2 files
1.mso.dll
2.msoutl.olb

But for different version of outlook, they are on different path.
But #import is compile time macro. So i am confused how to import/reference of these files at run time.

Please guide me how to do?

Here's how I #import Excel:

#import "libid:00020813-0000-0000-C000-000000000046" auto_search no_dual_interfaces rename("DialogBox", "excelDialogBox") rename("RGB", "excelRGB") rename("DocumentProperties", "excelDocumentProperties") rename("SearchPath", "excelSearchPath") rename("CopyFile", "excelCopyFile") rename("ReplaceText", "excelReplaceText")

Note the use of libid - that's constant across different versions and independent of the location of the file implementing the library.

The libid can be determined using the OLE-COM Object Viewer. Either open your DLL or OLB using the File->View TypeLib command or find the Outlook type library in the Type Libraries node of the tree-view.

As I'm a nice guy:

MSOUTL.OLB = 00062FFF-0000-0000-C000-000000000046
MSO.DLL = 2DF8D04C-5BFA-101B-BDE5-00AA0044DE52

Can i send Array in command line parameter of CeCreateProcess?

Hi all,

i want to send very big string in command line parameter but its not working so i think i break this string small parts and put in a array and than pass the array.

so please tell me can i do this.

or if not please tell me any other method for this.

thanks in advance.

To accomplish great things, we must not only act, but also dream;
not only plan, but also believe.

So, you're still stuck with that? Did I not tell you yesterday that passing a 70K+ long string as a command line is a very bad idea (leaving alone if it's possible or not)? May be you should read it again?

"_$h@nky_" wrote:

I provided a link to the page which discusses about this yesterday, which clearly pointed out the maximum length of the string that can be passed on as command line parameter. Did you read it or not?

"_$h@nky_" wrote:

Put it in a file and read it after the application starts up? Like I said yesterday...
