Odbgscript Updated to 1.65.4 by sunbeam

Updated to 1.65.4 (fixed issues concerning ASK and ASM commands in scripts).


Found bug here:

bool OllyLang:: DoASK(string args)
{
    string ops[1];
    string title;

    if(!CreateOperands(args, ops, 1))
        return false;

    if(GetSTROpValue(ops[0], title))
    {
        if (wndProg.hw!=NULL)
            InvalidateRect(wndProg.hw, NULL, FALSE);

        HINSTANCE hi = (HINSTANCE)GetModuleHandle("ODbgScript.dll");
        HWND hw = 0; //not modal but dialog need to be closed on plugin close.
        char* returned_buffer = (char*)DialogBoxParam(hi, MAKEINTRESOURCE(IDD_INPUT), hw, (DLGPROC) InputDialogProc, (LPARAM)title.c_str());
        if ((BYTE)returned_buffer != NULL)
        {
            string returned = returned_buffer;
            delete[256] returned_buffer;
            
            if(is_hex(returned)) 
            {
                variables["$RESULT"] = strtoul(returned.c_str(), 0, 16);
                variables["$RESULT_1"] = (int) (returned.length() / 2);            //size
            }
            else 
            {
                UnquoteString(returned, '"', '"'); // To Accept input like "FFF" (forces string)
                variables["$RESULT"] = returned.c_str();
                variables["$RESULT_1"] = (int) returned.length();
            }
        }
        else
        {    
            variables["$RESULT"] = 0; //****added this!!****
            Pause();
        }
        return true;
    }
    return false;
}

By doing that, if you leave the dialog box empty or press Cancel, it makes $RESULT 0 instead of empty as it used to..

Example:
ask "Enter text:" //here, when you press Cancel or don't type anything in, $RESULT = EMPTY..
cmp $RESULT,0
je #cancel
mov bla,$RESULT


Found another bug with ODbgScript.. When your variable holds addresses like B239E0, ODbgScript will fail to ASM them. Example:

eval "mov dword ptr [{GPA}],{cave}"
asm cave,$RESULT

For this case, with:

Command= eval "mov dword ptr [{GPA}],{cave}"
Result="mov dword ptr [A71074],B23A39"

Because of not putting a 0 in front of A71074, ODbgScript will error -> "unknown command".

Fixed here, in OllyLang.cpp:

[quote]else if(variables[op].vt == DW)
        {
            char buffer[12] = {0};
            if (hex8forExec)
                //For Assemble Command (EXEC/ENDE) ie "0DEADBEEF"
                sprintf(buffer, "%09X", variables[op].dw);
            else 
                sprintf(buffer, "%08X", variables[op].dw); //****changed from %X to %08X****
            value = buffer;
            goto values_ok;
        }

Now it should work fine;)

Script Execution, item 66
Line=66
Command= asm cave,$RESULT
Result=A
EIP= i
Values <---="mov dword ptr [00A71074],00B23A39" B23A01

试用了一下,怎么不能运行原来的脚本呢,不知道别人有没有这种现象,是何原因。
