Posted: Wed Jun 12, 2019 12:58 pm Post subject: executeCodeLocal "BitBlt" not working

Issue about call blit

Code:

local width = 300
local height = 100
local addressLocal = getAddress("BitBlt", true)
print(string.format('%08X',addressLocal))
local SRCCOPY = 0xCC0020
executeCodeLocal(addressLocal,
canvasFrmShadowMemoryView.Handle,
0, 0, width, height,
canvasMainMemoryView.Handle, 0,0, SRCCOPY)

I think I need to show all the code.

Code:

local mvForm2 = getMemoryViewForm()

local mi = createMenuItem(mvForm2.Menu)
mi.Caption = 'GH Tools'
mvForm2.Menu.Items.add(mi)

local mi2 = createMenuItem(mi)
mi2.Caption = 'MV Scanner'
mi.add(mi2)

mi3HBmethod = createMenuItem(mi2)
mi3HBmethod.Caption = 'HB method'
mi2.add(mi3HBmethod)
mi3HBmethod.OnClick = function()
if not CheckPreloadActions() then
return
end
mi3HBmethod.Enabled = false
mi4DBVMmethod.Enabled = false
mi5Stop.Enabled = true
mi3HBmethod.Checked = true
end

mi4DBVMmethod = createMenuItem(mi2)
mi4DBVMmethod.Caption = 'DBVM method'
mi2.add(mi4DBVMmethod)
mi4DBVMmethod.OnClick = function()
if not CheckPreloadActions() then
return
end
mi3HBmethod.Enabled = false
mi4DBVMmethod.Enabled = false
mi5Stop.Enabled = true
mi4DBVMmethod.Checked = true
end

mi5Stop = createMenuItem(mi2)
mi5Stop.Caption = 'Stop'
mi2.add(mi5Stop)
mi5Stop.OnClick = function()
mi3HBmethod.Enabled = true
mi4DBVMmethod.Enabled = true
mi5Stop.Enabled = false
mi4DBVMmethod.Checked = false
mi3HBmethod.Checked = false
mi5Stop.Enabled = false
end
mi5Stop.Enabled = false

function CheckPreloadActions()
local mainMemoryView = getMemoryViewForm().HexadecimalView
if mainMemoryView.DisplayType ~= dtByte then
showMessage("Set display type: view bytes")
return false
end
return true
end

executeCodeLocal only takes one parameter, you need to write a stub function first that reads out the parameter pointer to a block of actual parameters, and then pass that to the function you wish to call (next ce version has executeCodeLocalEx) _________________ Do not ask me about online cheats.
