193120CF - mov ecx,[eax+04]
Instruction is located at address 193120CF
The instruction pulls a value from [eax+04]
Register EAX equals 0403B8E0

0403B8E4 = (dword)0000000A(10)
EAX + 04 equals the address 0403B8E4
dword is the variable size (4-bytes)
0000000A is the value at that address in hex notation
(10) is the value at that address in decimal notation

Although I think I'm talking bullshit.
You said the following:
ECX=0000000A << -------------------- my value that want to hack

So I suppose the statement you want is:
mov [edx+20],ecx

So just do a coding injection, which changes:
mov [edx+20],ecx

for:
mov [edx+20],#1000 -- new value

Or simply change the value of ecx, before it writes to any statement:
mov ecx,#1000 --new value
mov [edx+20],ecx
