천객만래 [千客萬來] (It has an interminable succession of visitors)

Having problems with a ticket being submitted multiple times?

This article will show you how to disable the Submit button after it has been click and change the text label to Submitting, please wait...
 

  1. Make a backup copy of your existing index.php file.
     

  2. Open file index.php in a plain text editor, such as Notepad.
     

  3. Inside index.php find the first two occurrences of this code:

    <input type="submit"
     

  4. After this code add:

    onclick="this.disabled=true;this.value='Sending, please wait...';this.form.submit();"

    Remember, do this twice - the first two times you find code in step 3.

    The final code should look like this:

    <input type="submit" onclick="this.disabled=true;this.value='Sending, please wait...';this.form.submit();" 
     

  5. Save changes, upload the index.php file to your server and test it.
     

That's it! Now, when your visitors click the "Submit" button when submitting a ticket, the button will be be disabled with the Sending, please wait message until the post is complete.

CString -> char *

CString str;
str = "Hello";
char* ss = LPSTR(LPCTSTR(str));

 

char * --> CString

char ss[] = "Hello";
CString str;
str.Format("%s", ss);

(Format대신에 GetBuffer()를 써도 됩니다.)
 
지식인!
 
Environment: Compiled using VC6.0 Sp3 and tested using Win95/98 WinNT4.0 and Win 2000
Here are a few data Conversions with small examples :-

PART ONE :- DECIMAL CONVERSIONS
Decimal To Hexa :-
Use _itoa( ) function and set radix to 16.

 

char hexstring[10];
int number = 30;
itoa( number, hexstring, 16);

In hexstring is 1e.

Hexa To Decimal :-
a)You can use strtol function and you can specify base.

char * hexstring= "ABCDEF";
char * p;
int number = strtol(hexstring, &p,16);

b) Or you can use this too

bool HexToDecimal (char* HexNumber, int& Number)
{
char* pStopString;
Number = strtol (HexNumber, &pStopString, 16);
return (bool)(Number != LONG_MAX);
}


Decimal to Time :-

char *DecToTime(float fTime, char *szTime)
{
int nHrs, nMin, nSec;
fTime *= 3600;
nHrs = (int)fTime / 3600;
nMin = (int)(fTime - nHrs * 3600) / 60;
nSec = (int)(fTime - nHrs * 3600 - nMin * 60);
wsprintf(szTime, "%02d.%02d.%02d Hrs.Min.Sec.", nHrs, nMin, nSec);
return szTime;
}

PART TWO :- STRING CONVERSIONS
String to Hexa :-

sscanf(string, %04X, &your_word16);
// where string = your string and 04 = length of your string and X = hex


Hex to CString :-
CString Str;
unsigned char Write_Buff[1];
Write_Buff[0] = 0x01;
Str.Format("0x0%x",Write_Buff[0]);


COleVariant to CString :-
CString strTemp;
COleVariant Var;
Var = "FirstName";
strTemp = Var.bstrVal;
AfxMessageBox(strTemp);


CString to Char Pointer :-
a) CString MyString = "ABCDEF";
char * szMyString = (char *) (LPCTSTR) MyString;

b) char *pBuffer = new char[1024];
CString strBuf = "Test";
pBuffer = strBuf.GetBuffer(sizeof(pBuffer));

 

Char Pointer to CString :-
char * mystring = "12345";
CString string = mystring;


Double to CString including the fractional part :-
CString strValue,strInt, strDecimal;
int decimal,sign;
double dValue = 4.125;
strValue = _fcvt(dValue,6,&decimal,&sign);

// Now decimal contains 1 because there is only one digit before the .

strInt = strValue.Left(decimal); // strInt contains 4
strDecimal = strValue.Mid(decimal); // strDecimal contains 125

CString strFinalVal;
strFinalVal.Format("%s.%s",strInt,strDecimal); // strFinalVal contains 4.125

 

Double To CString :-
CString strValue;
int decimal,sign;

double dValue = 123456789101112;
strValue = _ecvt(dValue,15,&decimal,&sign);


CString To Double :-
strValue = "121110987654321";
dValue = atof(strValue);


CString to LPCSTR :-
CString str1 = _T("My String");
int nLen = str1.GetLength();
LPCSTR lpszBuf = str1.GetBuffer(nLen);
// here do something with lpszBuf...........
str1.ReleaseBuffer();


CString to LPSTR :-
CString str = _T("My String");
int nLen = str.GetLength();
LPTSTR lpszBuf = str.GetBuffer(nLen);
// here do something with lpszBuf...........
str.ReleaseBuffer();

CString to WCHAR* :-
CString str = "A string here" ;
LPWSTR lpszW = new WCHAR[255];

LPTSTR lpStr = str.GetBuffer( str.GetLength() );
int nLen = MultiByteToWideChar(CP_ACP, 0,lpStr, -1, NULL, NULL);
MultiByteToWideChar(CP_ACP, 0, lpStr, -1, lpszW, nLen);
AFunctionUsesWCHAR( lpszW );
delete[] lpszW;

 

LPTSTR to LPWSTR :-
int nLen = MultiByteToWideChar(CP_ACP, 0, lptStr, -1, NULL, NULL);
MultiByteToWideChar(CP_ACP, 0, lptStr, -1, lpwStr, nLen);


string to BSTR
string ss = "Girish";
BSTR _bstr_home = A2BSTR(ss.c_str());


CString to BSTR :-
CString str = "whatever" ;
BSTR resultsString = str.AllocSysString();


_bstr_t to CString :-

#include
#include
_bstr_t bsText("Hai Bayram");
CString strName;
W2A(bsText, strName.GetBuffer(256), 256);
strName.ReleaseBuffer();
AfxMessageBox(strName);

char szFileName[256];
GetModuleFileName(NULL,szFileName,256);
AfxMessageBox(szFileName);


PART THREE :- CHARACTER ARRAYS

Char array to integer
char MyArray[20];
int nValue;

nValue = atoi(MyArray);

 

Char array to float
char MyArray[20];
float fValue;

fValue = atof(MyArray);


Char Pointer to double :-
char *str = " -343.23 ";
double dVal;
dVal = atof( str );


Char Pointer to integer :-
char *str = " -343.23 ";
int iVal;
iVal = atoi( str );

 

Char Pointer to long :-
char *str = "99999";
long lVal;
lVal = atol( str );


Char* to BSTR :-
char * p = "whatever";
_bstr_t bstr = p;

Float to WORD and Vice Versa :-
float fVar;
WORD wVar;
fVar = 247.346;
wVar = (WORD)fVar; //Converting from float to WORD. The value in wVar would be 247
wVar = 247;
fVar = (float)fVar; //Converting from WORD to float. The value in fVar would be 247.00

# cstring to int

int 형 = _ttoi(cstring 형)


# int to cstring

cstring 형.Format( _T("%d"), int 형); 
 
* CString -> std::string

 

CString cs ("Hello");

  // Convert a TCHAR string to a LPCSTR
  CT2CA pszConvertedAnsiString (cs);

  // construct a std::string using the LPCSTR input
  std::string strStd (pszConvertedAnsiString);

 

 

* std::string -> CString

 

CString tmp;

string foo;

tmp = foo.c_str();
