Posted: Sun Jun 08, 2008 8:33 am Post subject: [Request] Help with C++ String -> Char Array

I have

Code:

String szString = "8D 23 74 3D FF 0A"

And i need to make it as

Code:

char Bytaz[] = {0x8D, 0x23, 0x74, 0x3D, 0xFF, 0x0A}

Of couse the szString is dinamyc(Text and size)~

Anyone know how to do it?

And please no GetDlg or sutch things heres a piece of code i was tryng

Code:

char StrToChar(int TehLength)
{
int NumberOfBytes = ((TehLength+1)/3);
char Temp;
char *TempBuffer = (char*)malloc(NumberOfBytes);
   for (int i = 1; i <= NumberOfBytes; i = i+3)
   {
      sprintf(TempBuffer,"%s%s, ",Form1->Edit1->Text[i],Form1->Edit1->Text[i+1]);
      *TempBuffer = Form1->Edit1->Text[i];// + Form1->Edit1->Text[i+1]);

      Temp = Temp+*TempBuffer;
   }
free(TempBuffer);
return Temp;
}

Thank you soo mutch for the support.

Lol. Dude...

Code:

Form1->Edit1->Text[i]

xD!!! This isn't delphi. There is no Form1, Edit1, Text...lol. Even if you're using MFC you don't even do it like that. Btw, you realize that you can just go

Code:

Bytaz = szString;

He uses Borland C++, I believe.

Wtf, you can do that. That's pretty stupid. No offense, I'm just saying, you're practically taking the fun out of C++. Now instead of getting text like this...

Code:

char *buffer;
int len = GetWindowTextLength(GetDlgItem(hwnd, IDC_EDIT));
if(len > 0) {
buffer = (char*)GlobalAlloc(GPTR, len+1);
GetDlgItemText(hwnd, IDC_EDIT, buffer, len+1);
}

You can do it so easily like this...

Code:

buffer = Form1->Edit1->Text;

It's just not fun.

While I do not like Borland products, that's not a good way to judge anything. Pretty much, you're telling him to reinvent the wheel, while there is a provided method for him to use. Not a good attitude at all.

I'm just saying I like the old method better, more fun to code. Other thing takes away from the "coding experience."

Code:

char * bytaz = szString

or, if you're keeping track of the array length or want to check for a null terminator in the char array, make the char array larger than you will need.

Code:

char[100] bytaz = szString

Ok i used

Code:

   char *bytaz = Edit1->Text.c_str();

DWORD addy = 0x887755;
if (CheckBox1->Checked == true)
{
   for (int i = 0; i <= Edit1->Text.Length()+1; i=i+3)
   {
      *(BYTE*)addy = bytaz[i];

      addy++;
   }
}

But it writes as ASCII =/
I need it to write the bytes from the text box not the text
Anyone can help?

Was there something wrong with your previous thread that you had to repost? http://forum.cheatengine.org/viewtopic.php?t=246296 xor gave you a method, wiccaan gave you code. _________________
