        invoke  GetFileSize,fileSize,0

        mov     [fileSize],eax
        invoke  GlobalAlloc,0,fileSize
        mov     [dwBufferSize],eax
        cmp     [dwBufferSize],0
        je      .fileNtAlloc
        invoke  ReadFile,[hFile],dwBufferSize,fileSize,dwTextLength,0
        mov     edi,[dwBufferSize]
        mov     ecx,[fileSize]
        mov     esi,stxt
        mov     al, byte[esi]
        call    sloop

.inValHandle:
        invoke  MessageBox,[hwnddlg],text2,caption,NULL+MB_OK
        call    endn

typedef
You can make a procedure that you can pass a base string and the string to find.

Code:
proc search bString,szFind
ret
endp

proc main

ReadFile,data

stdcall search,data,"string to search"

The WinAPI provides a strstr function for searching strings - http://msdn.microsoft.com/en-us/library/bb773436(v=vs.85).aspx
