I modified the function processPatternScan of Kalamity/classMemory to Scan memory regions AllocationProtect is PAGE_NOACCESS
processPatternScanModified(startAddress := 0, endAddress := "", aAOBPattern*)
{
address := startAddress
if endAddress is not integer
endAddress := this.isTarget64bit ? (A_PtrSize = 8 ? 0x7FFFFFFFFFF : 0xFFFFFFFF) : 0x7FFFFFFF
MEM_COMMIT := 0x1000, MEM_MAPPED := 0x40000, MEM_PRIVATE := 0x20000
PAGE_NOACCESS := 0x01, PAGE_GUARD := 0x100, PAGE_READWRITE := 0x04
if !patternSize := this.getNeedleFromAOBPattern(patternMask, AOBBuffer, aAOBPattern*)
return -10
while address <= endAddress ; > 0x7FFFFFFF - definitely reached the end of the useful area (at least for a 32 target process)
{
if !this.VirtualQueryEx(address, aInfo)
return -1
if A_Index = 1
aInfo.RegionSize -= address - aInfo.BaseAddress
oldProtect := aInfo.Protect
if (aInfo.State = MEM_COMMIT) {
If ((aInfo.Protect & (PAGE_NOACCESS | PAGE_GUARD))){
; if the page is not readable, make it readable
dllcall("VirtualProtectEx", "ptr", this.hProcess, "ptr", address, "ptr", aInfo.RegionSize, "uint", PAGE_READWRITE, "uint*", oldProtect, "int")
}
}
if (aInfo.State = MEM_COMMIT)
&& aInfo.RegionSize >= patternSize
&& (result := this.PatternScan(address, aInfo.RegionSize, patternMask, AOBBuffer))
{
If ((aInfo.Protect & (PAGE_NOACCESS | PAGE_GUARD))){
; restore the old protection
dllcall("VirtualProtectEx", "ptr", this.hProcess, "ptr", address, "ptr", aInfo.RegionSize, "uint", oldProtect, "uint*", 0, "int")
}
if result < 0
return -2
else if (result + patternSize - 1 <= endAddress)
return result
else return 0
}
If ((aInfo.Protect & (PAGE_NOACCESS | PAGE_GUARD))){
; restore the old protection
dllcall("VirtualProtectEx", "ptr", this.hProcess, "ptr", address, "ptr", aInfo.RegionSize, "uint", oldProtect, "uint*", 0, "int")
}
address += aInfo.RegionSize
}
return 0
}
but it's not working, i don't know why, can anyone help me to make it work.
I tried using VirtualProtectEx function, but something is wrong
