I tried all day long to send a 'CTRL' input to TeamSpeak to activate voice.

I used PostThreadMessage and PostMessage to TeamSpeak Thread without success.

Is it possible to do ?

TeamSpeak probably uses DirectSound and therefore probably also uses DirectInput. And DirectInput reads the scan codes directly from the kernel input stream. Try using the SendInput() or keybd_event() functions to simulate your keystrokes. These functions are capable of inserting data into the kernel input stream.

The following function will work as well:

void _declspec(naked) __stdcall SendInput(UINT nInputs, LPINPUT pInputs, int cbSize)
{
	__asm
	{
		mov eax, 000011f6h
		mov edx, 7ffe0300h
		call dword ptr [edx]
		retn 000ch
	}
}

Unfortunately you are correct,

In ntdll at location 7ffe0300h resides the SYSENTER instructions as seen below:

7FFE0300      8BD4    MOV EDX,ESP
7FFE0302      0F34    SYSENTER
7FFE0304      C3      RETN

I apologize for the hacked-up code, I wrote the function as I was sipping my first cup of coffee and inserted one of my bad habits of JMPing to known offsets.

It would be a better solution to write the function as:

void _declspec(naked) __stdcall SendInput(UINT nInputs, LPINPUT pInputs, int cbSize)
{
	__asm
	{
		mov eax, 000011f6h
		mov edx, esp
		SYSENTER
        }
}

The function could also be written as follows:

void _declspec(naked) __stdcall SendInput(UINT nInputs, LPINPUT pInputs, int cbSize)
{
	__asm
	{
		mov eax, 000011f6h
		lea edx, [esp+4]
		int 2eh
        }
}

I got a error testing funcions Randor made... What can it be?

'SendInput' : redefinition; different basic types
winuser.h(5297) : see declaration of 'SendInput'

I'm coding C

Re: Send Key Input

Randor 16-Mar-08 18:36

Randor

It means 'SendInput' is already defined. Rename the function to somthing other than SendInput to avoid the conflict.

I am wondering why you are suggesting inline assembly to do this as OP already has access to SendInput() API.

Re: Send Key Input

Im not suggesting inline assembly.
I instructed the poster on how to use the SendInput() function and presented several other options. I am simply sharing my knowledge.

Help VS2008: assigning a returned string to an edit control

Hamid intact15-Mar-08 10:36

Hi! Everybody,
I am new to programming and this is my first post here. I have problem with assigning a string which is returned by the active component to my edit control box. I will appreciate any hint if possible.
I have created a dialog based MFC standard application and I am using a button to simulate the problem by clicking on the button, but without any progress. This is the description of what I have done:
- Created a C++ dialog based MFC application
- inserted an ActiveX component and created a member variable called “m_Active“
- inserted an edit control and created a member variable called “m_Edit”
- inserted a button and crated a member variable called ”m_Button”

void CTestDlg::OnBnClickedButton()
{
// TODO: Add your control notification handler code here
m_Active.mConnect(0);
m_Active.mListening(1,2000);
m_Active.mStartServers(1,2001,2002,2003);
m_Active.mStreamVideo(1);
m_Active.mStreamAudio(1);
m_Edit.SetString(mGetLocalHostName);

}
……………………………………………………………………………………………………………………
Every thing works fine untill the last line
M_Edit.SetString(mGetLocalHostName);

I have to add that “mGetLocalHostName” forces the ActiveX component to return the string wich I am intending to have in the Edit control.

I hope I have been able to describe the problem I have. And I appriciate any kind of help.

What kind of a member variable is m_Edit? Since you are calling SetString() upon that member variable, I am assuming it is a COleVariant. Try using a control variable instead of it and call SetWindowText(mGetLocalHostName) on it instead.

Hi Rajesh!
Thank you for showing interest in this problem.
I did the changes you suggested.
“m_Edit” is a control variable member now. And after changing the code to

void CTestDlg::OnBnClickedButton()
{
// TODO: Add your control notification handler code here
m_Active.mConnect(0);
m_Active.mListening(1,2000);
m_Active.mStartServers(1,2001,2002,2003);
m_Active.mStreamVideo(1);
m_Active.mStreamAudio(1);
m_Edit. SetWindowTextW(m_server.mGetLocalHostName);

}

I get an error which says:

error C3867: 'CTestserver::mGetLocalHostName': function call missing argument list; use '&CTestserver::mGetLocalHostName' to create a pointer to member

Could you please lead me to a solution?

With thanks in advance.

Hi David!

"mGetLocalHostName" returns a string containing the domain name and service of the local socket endpoint.

Then why are you doing like this: m_Edit. SetWindowTextW(m_server.mGetLocalHostName);? Won't m_Edit.SetWindowTextW(mGetLocalHostName) suffice? Just try m_Edit.SetWindowTextW(_T("Hello world"));. Is that working? If yes, the problem is not with SetWindowTextW. Smile | :)

Hi Rajesh!
m_Edit.SetWindowTextW(mGetLocalHostName) end with an error (undeclared identifier)
m_Edit.SetWindowTextW(_T("Hello world")); works fine
I have changed the last line as
m_ip. SetWindowTextW(m_server.mGetLocalHostName());
and I get the returned string from ActiveX component in the Edit kontroll.
It works fine now. Thank you. I could not have been succseded without the help from Krmed and you.

It would appear that you are trying to call a method (mGetLocalHostName) in your ActiveX, but are just passing the method name - you're missing the call and arguments.

Perhaps it should be:

m_Edit. SetWindowTextW(m_server.mGetLocalHostName(arguments_go_here if any));

Hope that helps.

Hi Krmed!
You are right. I have been missing () för the argument.
m_ip. SetWindowTextW(m_server.mGetLocalHostName());
It works fine now. Thank you. I could not have been succseded without the help from Rajesh and you.

Executable icon in visual studio 2005

Hello, i know this will sound kind of a noob question, but i cannot find any support on this anywhere.
I made a project in visual studio c++ (non-managed) and every time I need to change the icons, the executable will get a random icon (i guess it's the first icon i add at the resource editor.)
Is there any way to set the icon i want to the exe file in the editor without those time consuming workarounds?

best regards Smile | :)

Correct.

Time-consuming workarounds? How about just leaving one icon (with an ID of 1)
as the app's icon (used by the system shell) and add any other icons you need to the
resources?

How to Merge two or more CImageList objects to a single one

15-Mar-08 8:10

Dear all,

I have,
CImageList ImgList1;
CImageList ImgList2;
CImageList MasterImgList;

I have added several "CBitMap" objects to the "ImgList1" and "ImgList2" using CImageList::Add( CBitmap* pbmImage, COLORREF crMask ) method.

Now I would Like to Merge "ImgList1" and "ImgList2" to the "MasterImgList".
That is after merging, "MasterImgList" contains both the contents of "ImgList1" and ImgList2".

Please help me..

Thanks in Advance

why CImageList:: ( Add, Copy, Remove, Replace) member functions can't be used to achieve the image list merge.
