Convert unicode text into byte stream, then convert that byte stream into hex.

Thank you Manish Rastogi.
Did you mean char array by "byte stream"?
I tried to convert my string to char array and then convert to hex. Still getting wrong results Smile | :)

Can you give me an example, please?

Of course!

CString UnicodeToHex(CString unicode){
	char* unicode_((char*)unicode.GetString());
	CString hex=L"";
	for (int i=0;i<unicode.GetLength();i++)
	{
		hex.Append(L"%");
		hex.AppendFormat(L"%x",unicode_[i]);
	}
	return hex;
}

unicode_ is serving no purpose in this code snippet.

With input of %F1%E8%EC%E2%EE%EB, what are you expecting the output to be?

The above sentence is wrong. The hexadecimal representation of the UNICODE characters символ is
{ 0x0441, 0x0438, 0x043c, 0x0432, 0x043e, 0x043b}.

for (int i=0;i<unicode.GetLength();i++)

In the above statement, the index i should run for (unicode.GetLength() * 2).

CPallini, thank you for your reply.

I have a web form that I need to submit programmatically and data should be in unicode.
When I submit that web form using Firefox with the text символ, this is what Firefox is sending to the server:

%F1%E8%EC%E2%EE%EB

And I'm trying to send the same thing programmatically.

So if символ = %F1%E8%EC%E2%EE%EB is wrong, why Firefox is sending it like that?
Is it because of charset=WINDOWS-1251 in the source code of the web page:

<head>
 <meta http-equiv="Content-Type" content="text/html; charset=WINDOWS-1251" />
</head>
<body>
 <form action="i.php" method="POST">
  <input type="text" name="txt" />
  <input type="submit" value="Submit" />
 </form>
</body>

What should I do to convert to the same hex format Firefox is using?

Please let me know, if I'm not clear enough.

Ok, I figured it out.
It is because of the charset (windows-1251).

And to convert them to the hex format that firefox is using(windows-1251 charset), I had to replace each russian letter by hand with its hex equivalent in windows-1251 charset.

I know, it's not the best way, but I couldn't find better one:
Just in case, if someone needs it:

/*----------------------------------*/
//***Windows-1251 charset to Hex***
//If works, it is written by
//Siroj Matchanov(aka tech,msn92)
//if it doesn't I dunno who wrote it
//Recources used:
//http://www.science.co.il/language/Character-Code.asp?s=1251
/*----------------------------------*/

void Win1251ToHex(
	CString &input, /*(windows-1251/ascii charset)*/
	CString &hex /*Output (in hex)*/
)
{
hex=L"";
for (int i=0;i<input.GetLength();i++)
{
	//each char represents a unique number (e.g. int('Ў')=1038)
	int ii=input[i];
	//russian letters represent numbers that are greater than 1000
	if(ii>1024){
			//---------------------------------//
			//   Uppercase&Lowercase Letters   //
			//  А-Я-а-я  (1040-1071-1072-1103) //
			//---------------------------------//
	   if((ii>1039)&&(ii<1104)){
	     BYTE x=0xC0;
	     x=x+(ii-1040);
	     hex.Append(L"%");
	     hex.AppendFormat(L"%x",x);
	   }else{
			//------------------------//
			//    Special symbols     //
			//------------------------//
		switch (ii)
		{
		case 8218:
			{
				hex.Append(L"%82");//‚
				break;
			}
		case 8222:
			{
				hex.Append(L"%84");//„
				break;
			}
		case 8230:
			{
				hex.Append(L"%85");//…
				break;
			}
		case 1038:
			{
				hex.Append(L"%A1");//Ў
				break;
			}
		case 1118:
			{
				hex.Append(L"%A2");//ў
				break;
			}
		case 1025:
			{
				hex.Append(L"%A8");//Ё
				break;
			}
		case 1105:
			{
				hex.Append(L"%B8");//ё
				break;
			}
		case 8470:
			{
				hex.Append(L"%B9");//№
				break;
			}
		}
	   }
	//Because they are not used usually,

	//If you want them to be in windows-1251 charset format hex...
	//...then continue the code yourself please :)
	//(Almost) any other symbol in windows-1251 charset has

		hex.AppendFormat(L"%x",ascii[i]);

Hi all,

I m using CeCreateProcess to create process,

CString CMDdata;
PROCESS_INFORMATION pi;
CeCreateProcess(L"Test.exe",T2CW((LPCTSTR)CMDdata),NULL,NULL,FALSE,0,NULL,NULL,NULL,&pi);

Here CMDdata have 70,507 characters ,when i debug my code after execution of this line control goes and not return to next line,and application becomes not responding or may crashing occur.

while if CMCData have less number of charcter than its working fine .please tell me the maximum value for this.

and if possible please explain me with any other example.
or any other way.
please help me for this.

thanks in advance.

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

70K+ characters as a command line argument?! OMG | :OMG:

Can't you let the application start and read this string from a file?! Not to mention you're doing mobile development and that you should use resources carefully.

According to google maximum command line legth for CreateProcess ,which is CeCreateProcess alternative for desktop machines is 32767 characters [^].I suppose this value is even smaller for the CE function.

There are event handlers for every such control. Have you tried looking into the documentation of such controls? Have you searched for examples? Please do it. You might also buy a good book on MFC.

As a first step I would run the program under the debugger and try to find out where the error occurs. this should give some idea of the general problem area from where you can narrow it down to the more specific point of failure. Adding some debug trace code might also be useful.

Please see my previous message. You need to try and discover where the program is failing, and then examine the code in that area. Use the DEBUG mode and breakpoint facility to narrow the problem down. It is no good sending the complete code to me as I have no idea what the program is trying to do.
