but when i drag control on the form in x64, crash the application.
i rebuile it in x64 and test it again but it didnt work.
pls help me.
how i can create x64 support ocx in visual c++ 6?

Did you set MachineX64 (/MACHINE:X64) and other parameters for your project?

Hi 
Try setting a ocx project in VC9 for x86 and then see which options it sets for it.
maybe it helps

it's a chatting tool
and i use spy++ get the RichEdit20A handle from the dialog
but i can't use the handle to get the text
maybe it shields WM_GETTEXT msg
how can i get the text in another way??

Accessing data of another process isn't that simple...that's one of the main points of protected mode. What do you want to do that involves using spy++ and getting text from a control in another process?

Most IM programs support plugins, maybe it would be easier to write one if the one you want to target there does so? Anyhows, docs say that WM_GETTEXT works over process boundaries for some controls, and for some it doesn't, so i guess for rich edit it doesn't work. You could try a trick but it's not too safe and reliable. You could allocate shared memory, lock it, post WM_GETTEXT to the control passing the address of the shared memory block, wait a while (sadly you can't really know if the rich edit control has processed that message yet or not) and then you should have the text in the memory block. However, this can lead to crashes and asynch problems. You could try for example filling the buffer with 1s, and then after you sent the message keep checking for a 0 character, assuming that you have allocated a big enough buffer, when the 0 is there then the rich edit has probably finished copying its text into the buffer (since 0 should be the last character of the text and we assume it is copying the text from its start to its end). Combining that with maybe some timeouting...
Or on a different aproach, you could inject a DLL into the process that hooks itself to the rich edit control and could for example when the control gets WM_SETTEXT copy the text into some shared buffer and notify your process of the change.
This all is just ideas, don't know if any of it could ever work.

Here, if i wanna modify a register key which need administrator priority, how to do it?
if use normal function RegOpenKeyEx and RegSetValueEx with a KEY_ALL_ACCESS will get a error that the access is denied.
Any ideas?
Regards.

Did you try using AdjustTokenPrivileges[^] to enable SE_TAKE_OWNERSHIP_NAME privilege and then open the registry key with WRITE_OWNER access?

oh, im haven't yet. In fact, i know little about the security privileges of windows internals.
And, would you like to give me a flow of resolve such task using AdjustTokenPrivilege function?
|

Well, your making me lose my beauty sleep. And believe me I need it. Perhaps you should read this:
Enabling and Disabling Privileges in C++[^]
Just copy and paste that Microsoft example code into your project. You would use it like this:
BOOL GetYourPermission()
{
HANDLE token = 0;
if(TRUE == OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &token))
{
return SetPrivilege(token, SE_TAKE_OWNERSHIP_NAME, TRUE);
}
return FALSE;
}
Btw, I hope your logged in under the Administrator account.

Thanks. I will have a try.
|
|
|
|

I have tried like following code:
int ret = GetYourPrivilege();
HKEY key;
DWORD err = RegCreateKeyEx(HKEY_LOCAL_MACHINE,_T("SYSTEM\\CurrentControlSet\\Enum\\Root\\MYKEY"),
0,NULL,0,KEY_ALL_ACCESS,NULL,&key,NULL);
it still get failed with an error code:ERROR_ACCESS_DENIED
what's wrong? I do logined with admin account.

I should have explained it better. You need to add yourself to the access control list[^] before you can modify that area of the registry.

Thats a very interesting registry key your attempting to access/write as it controls drivers/filter drivers for system hardware. Are you installing a filter driver or something? That particular registry key can also be used for malware, do you mind me asking why you need to manually modify that registry key? If you are installing a device driver or upper/lower level filter driver then there are better solutions provided for driver installation.

hehe, it doesn't matter i tell you what i want. I only want to install a lower level filter driver to the system. The driver is provided by a third-party tool. I know how to modify the register to install it and make it work perfectly. I know write a simple .inf install file is suitable, but, the problem is, im not a driver developer with little driver acknowledge. And, i'll read the articles you provided and have a try immediately.
Further more, any further advise is appreciated,too.Thanks.
Regards.

The third party driver developer should have provided an INF file for you. Microsoft provides the Setup API[^] which is designed to make it easier to correctly install device drivers. There is sample code provided at the that URL.
