Problems sending mouse inputs using SendInput - C / C++ / MFC Discussion Boards

I don't have another suggestion yet... Frown | :(

Or you can use any of the states like LVIS_CUT, etc. to do the same...
If you get a better method, please let me know too. Smile | :)

Oh! It is only a suggestion as I didn't try it yet.

I meant that if you are not using the states, for example LVIS_CUT state, it can be used as a disable item state.
So u can set the state of the item ( that you want to be disabled ) to the CUT state and in DrawItem you can check the state of each item and if it is in CUT state, you can draw it as disabled.

ok now i follow Smile | :)

but this is good only for the drawing, because i will still need to implement onitemchaning and prevent the selecting for that state....so it is just like puting an item data...

thanks

Hi,
I am facing problems in sending mouse clicks via SendInput API.

Mouse clicks are being sent but at the X,Y co-ordinates.

I am mapping my monitor to the (0,0,65535,65535) virtual monitor as needed by the SendInput. But the mouse clicks are always reported at the "current cursor location" (I am testing it with the notepad) irrespective of the X,Y co-ordinates specified.

Here is the code.

void SendMouseInput(unsigned int iX,unsigned int iY)
{
MOUSEINPUT mousei={0};
INPUT Input={0};
BlockInput(true);
::ZeroMemory(&Input,sizeof(INPUT));
::ZeroMemory(&mousei,sizeof(MOUSEINPUT));
mousei.dx=VirtualXFromAbsoluteX(iX);
mousei.dy=VirtualYFromAbsoluteY(iY);
mousei.dwFlags=MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_LEFTDOWN;
Input.type = INPUT_MOUSE;
Input.mi = mousei;

if(::SendInput(1,&Input,sizeof(Input))==0)
ShowError("SendMouseInput");

mousei.dwFlags=MOUSEEVENTF_ABSOLUTE|MOUSEEVENTF_LEFTUP;
Input.type = INPUT_MOUSE;
Input.mi = mousei;

if(::SendInput(1,&Input,sizeof(Input))==0)
ShowError("SendMouseInput");
BlockInput(false);
Sleep(1000);

}
static int VirtualXFromAbsoluteX ( int iX )
{

double Width = GetSystemMetrics ( SM_CXSCREEN ) ;
double Val = ( ((double)iX/Width) * (double)(65535) ) ;

double Ceil = ceil ( Val ) ;
double Floor = floor ( Val ) ;

if ( Ceil > Floor )
{
iX = (int)Ceil ;
}
else
{
iX = (int)Floor ;
}
return ( iX ) ;
}
static int VirtualYFromAbsoluteY ( int iY )
{

double Height = GetSystemMetrics ( SM_CYSCREEN ) ;
double Val = ( ((double)iY/Height) * (double)(65535) ) ;

double Ceil = ceil ( Val ) ;
double Floor = floor ( Val ) ;

if ( Ceil > Floor )
{
iY = (int)Ceil ;
}
else
{
iY = (int)Floor ;
}
return ( iY ) ;
}

void ShowError(LPTSTR lpszFunction)
{
TCHAR szBuf[80];
LPVOID lpMsgBuf;
DWORD dw = GetLastError();

FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
dw,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR) &lpMsgBuf,
0, NULL );

wsprintf(szBuf,
"%s failed with error %d: %s",
lpszFunction, dw, lpMsgBuf);

::MessageBox(NULL, szBuf, "Error", MB_OK);

LocalFree(lpMsgBuf);
}

Am I doing something wrong?

PS: I am able to send key board events using SendInput.

Thanks a load in advance.

Hi Subra,

Try debugging the code by putting a break point over the event.

Appu..
"If you judge people, you have no time to love them."

I tried all possible debugging.
The data is going to SendInput correctly.
But the click is happening at the point where my mouse pointer is currently pointing. I also set windows hooks to monitor the mouse events before any application gets its hands on it. There also I see that the x,y co-ordinates are coming wrongly.

Function();
{...

m_nftp.MoveFile("/"+NameSelected,"C:\\"+NameSelected,
FALSE,TRUE);
m_nftp.LogOffServer();
//SetFileName(Filetitle,path+filetitle)
theApp.m_pWinamp->SetFileName(NameSelected,
"C:\\"+NameSelected);

theApp.m_pWinamp->Wload(); //Load WinAmp's playlist

My problem is that Winamp cant load the life altought (after manually i can add it )(file not corrupted)

Is a way to delay so Winamp can load its Playlist ? Big Grin | :-D

Can u give me few more details of the problem ??

Appu..

Can you be more specific

BOOL CMainFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{

pCon=pContext;
m_wndSplitter.CreateStatic(this,2,1);
m_wndSplitter.CreateView(0,0,RUNTIME_CLASS(CView1),CSize(100,100),pContext);
m_wndSplitter1.CreateStatic(&m_wndSplitter,1,2,WS_CHILD|WS_VISIBLE,m_wndSplitter.IdFromRowCol(1,0));

m_wndSplitter2.CreateView(1,0,RUNTIME_CLASS(CView2),CSize(400,400),pCon);
}
iam not getting any error wnen the same code in SwitchView(CString str)
fn is written in on OnCreateClient(.....) but it getting error it is written in SwitchView.where switch view is a fn called when a tree item is clicked

*********Heere i want to get a spiltter when an event is arised send me a gud solution.***********
...............sahaja

In case of the code in OnCreateClient(...) it is working because the splitter window is created there for the first time.
But if you want to change the view in the splitter window at runtime then you have to follow different procedure. Its not just simple delete one view and create another.;P

plz give me a brief idea of the procedure to be followed.
Thanks

Hi,
I am lookoing for an an example in Visual C++ how to store/laod a TreeView in database, and show the hierachical data in a treeview.
In each row in the database there is an ID and a PARENTID

Thank you

Hello guys I am beginner to MFC threading. Can any body give me a link to samples for learning multi threaded programming (other then MSDN)

Thank You

Search codeproject with multithreading in the search box.

Somethings seem HARD to do, until we know how to do them.

The first book i read is program windown in c (win32api) .When i come here i see that many u use MFC. Is MFC app is faster or easy to program than win32api.
i also see that i write code using gdi++, and i bring it to another computer, it'll not work because lack of dll.
MFC is the same???.
If u have good book and u want me read it, let send me at "sea.loves.you@gmail.com". Thanks
And i alway get problem that is when i write my app and it run well in my computer but when i bring it to another it can't. I try to copy some dll required, some app work and some don't. mysetting is incorrect,isn't it?
I use .Net 2005.
Another problem: when i write program, i compile and it run well, but at another time when i chose Rebuild solution, and i run my app, but it alway drop the message that can't not find msvc80....( dont remember). Why?
Thanks.

I think three question
1-?
2-maybe you use from serivces that are install only in your computer
3-Can you be more specific
