破解后发现WinXPSP2下运行正常,而在Win2KSP4下运行时有两个Bug:
(1)端口号及相机选择ComboBox下拉框无法显示完全;
(2)托盘区小图标无法显示。如下图:
------------------------------------------------------------------------------------------------------
修正原版存在的Win2K下Combobox不能全部显示的Bug:
------------------------------------------------------------------------------------------------------
需要修改两处ComboBox的显示错误,错误原因在于ComboBox控件的初始化高度太小,Win2K下系统不能自动调整高度导致的。
而WinXP下系统会自动调整,所以WinXP下显示正常。
第一处端口ComboBox初始化:
0040E4D6 |. 8D4C24 3C LEA ECX,DWORD PTR SS:[ESP+3C]
0040E4DA |. 897C24 3C MOV DWORD PTR SS:[ESP+3C],EDI
0040E4DE |. C74424 44 390000>MOV DWORD PTR SS:[ESP+44],39 //宽度
0040E4E6 |. 897C24 40 MOV DWORD PTR SS:[ESP+40],EDI
0040E4EA |. C74424 48 140000>MOV DWORD PTR SS:[ESP+48],14 //14就是初始高度;Height of COMX
0040E4F2 |. 8908 MOV DWORD PTR DS:[EAX],ECX
0040E4F4 |. 8B56 04 MOV EDX,DWORD PTR DS:[ESI+4]
0040E4F7 |. 8D9E 88010000 LEA EBX,DWORD PTR DS:[ESI+188]
0040E4FD |. 52 PUSH EDX
0040E4FE |. 8BCB MOV ECX,EBX
0040E500 |. E8 5BF7FFFF CALL webcam.0040DC60 ; Init COMX Combobox
第二处分辨率ComboBox初始化:
00422885 . 895C24 28 MOV DWORD PTR SS:[ESP+28],EBX
00422889 . 896C24 30 MOV DWORD PTR SS:[ESP+30],EBP
0042288D . C74424 2C 7A0000>MOV DWORD PTR SS:[ESP+2C],7A //宽度
00422895 . C74424 34 8E0000>MOV DWORD PTR SS:[ESP+34],8E //8E减去上面的7A就是初始高度,Height of Combobox Resolution
0042289D . 8908 MOV DWORD PTR DS:[EAX],ECX
0042289F . 8B56 04 MOV EDX,DWORD PTR DS:[ESI+4]
004228A2 . 8DBE 04020000 LEA EDI,DWORD PTR DS:[ESI+204]
004228A8 . 52 PUSH EDX
004228A9 . 8BCF MOV ECX,EDI
004228AB . E8 A04F0000 CALL webcam.00427850
虽然可以直接修改初始化高度值和ComboBox的样式值来正常显示,但是显示效果会与这个软件的XP显示样式不协调。
且有时出现滚动条与选择元素不同步的现象,采用如下方法修复,可保证在不破坏其XP显示样式的情况下在2K下正常显示:
在ComboBox填充完毕后,获取填充元素个数和句柄,用SendMessage函数,发送消息CB_GETCOUNT,获取元素个数,
发送消息CB_GETITEMHEIGHT,获取元素高度,然后[高度]乘以[元素个数+1],获得总高度,确保全部元素都能显示,
再用SetWindowPlacement函数重新设置ComboBox窗口的高度即可。具体实现方法如下:
已知条件:
[00492458] GetMoudleHandleA函数地址
[00492440] GetProcAddress函数地址
[004921A8] SendMessageW函数地址
00489934 "USER32.dll"字串
(1)找空白处写入初始化数据:
00489950 写入字串"SetWindowPlacement"
00489970 写入字串"GetWindowPlacement"
00489990开始 用于保存WINDOWPLACEMENT结构
00489990写入双字"2C 00 00 00"// 结构长度2Ch字节
[004899B0]-〉top
[004899B8]-〉bottom
004899C0 dword用于保存ComboBox的句柄
004899C4 dword用于保存ComboBox的ItemCount个数
修改后如下:

(2)第一处修改:
在0042C981处,端口ComboBox填充完毕,此时[ESI+84]-〉ComboBox的句柄
0042C981 |. 33FF XOR EDI,EDI
0042C983 |> 8B4C24 14 MOV ECX,DWORD PTR SS:[ESP+14]
0042C987 |. 8B96 84000000 MOV EDX,DWORD PTR DS:[ESI+84]
改为:

0042C986 90 NOP
0042C987 8B96 84000000 MOV EDX,DWORD PTR DS:[ESI+84]
空白00489300处写入补丁1代码:

00489306 E8 E0030000 CALL webcam.004896EB //重新设置ComboBox控件高度
0048930B 33FF XOR EDI,EDI

00489311 - E9 7136FAFF JMP webcam.0042C987
(3)第二处修改:
在0042AD14处,分辨率ComboBox填充完毕,此时[ESI+8C4]-〉ComboBox的句柄
0042AD14 |. 8B86 C4080000 MOV EAX,DWORD PTR DS:[ESI+8C4]
0042AD1A |. 6A 01 PUSH 1 ; /Erase = TRUE
0042AD1C |. 6A 00 PUSH 0 ; |pRect = NULL
0042AD1E |. 50 PUSH EAX ; |hWnd
0042AD1F |. FF15 90214900 CALL DWORD PTR DS:[<&user32.InvalidateRect>] ; \InvalidateRect
改为:
0042AD14 - E9 E7E60500 JMP webcam.00489400 //跳至补丁2处
0042AD19 90 NOP
0042AD1A |. 6A 01 PUSH 1 ; /Erase = TRUE

0042AD1E |. 50 PUSH EAX ; |hWnd
0042AD1F |. FF15 90214900 CALL DWORD PTR DS:[<&user32.InvalidateRect>] ; \InvalidateRect
空白00489400处写入补丁2代码:
00489400 8B86 C4080000 MOV EAX,DWORD PTR DS:[ESI+8C4] ; hwnd
00489406 E8 E0020000 CALL webcam.004896EB //重新设置ComboBox控件高度

00489411 - E9 0419FAFF JMP webcam.0042AD1A
(4)空白004896EB处写入重新设置ComboBox控件高度补丁代码:
注意!别忘了用Lord-PE把其所在区段属性修改为可写,因为补丁代码要向其中动态写入数据。

------------------------------------------------------------------------------------------------------
跟踪调试发现,00415584处,比较程序的不同状态并设置相应的系统托盘区图标:
eax=0表示端口号Invalid 对应图标句柄在[ECX+8A4]
eax=1表示端口号正常,处于未连接状态 对应图标句柄在[ECX+8A0]
eax=2表示端口号处于连接状态 对应图标句柄在[ECX+8A8]
eax=3表示端口号正常,处于连接正在断开状态 对应图标句柄同eax=1
可用LoadIcon函数获取相应图标句柄,并分别替换上面三个地址的图标句柄,以取得正常的显示效果。
