Simulate click on Toolbar button programmatically

[sohail_k]

Hi,
I have a VB application that contains a toolbar.
I want to write an application (using Win32 API) that will simulate a click on the VB application toolbar button.
I have enumerated all the windows and found my VB app window. Then I enumerated the child windows of VB app and got a handle to its Toolbar.

Now when I use SendMessage(toolbarHandle, TB_PRESSBUTTON,1,MAKELONG(TRUE,0));
Fails.
Also other messages to VB app toolbar fail using SendMessage.

Can someone please tell me how to do it.

Thanks in advance

I would suggest mouse_event (superseded) or SendInput API (User32.dll).

Thanks John,
I'll try that and let you know if it worked for me.

I've done this a number of times:

RECT rc;
SendMessage(hToolbar, TB_GETITEMRECT, iIndex, (LPARAM) &rc);
PostMessage(hToolbar, WM_LBUTTONDOWN, NULL, MAKELPARAM(rc.left, rc.top));

(Edit: though not from VB)

If the toolbar action results in a WM_COMMAND, why not send a WM_COMMAND to the toolbar's owner instead of sending the toolbar some mesage and then the toolbar sending a WM_COMMAND to it's owner ?

Hi JohnCz,
I check SendInput API, I think it will work for me, but the problem is that I have to know the mouse co-ordinates i want to click on.
If I don't find any other way to do it then I'll use SendInput. Thanks.
Have a nice day

Hi Bond,
RECT rc;
SendMessage(hToolbar, TB_GETITEMRECT, iIndex, (LPARAM) &rc);
PostMessage(hToolbar, WM_LBUTTONDOWN, NULL, MAKELPARAM(rc.left, rc.top));

doesn't work for me.
Is it because VB uses an ActiveX control????
Any idea?

you've got to run it in the same process, try so:

DWORD dwProcessID;
SIZE_T nNumberOfBytesRead;

GetWindowThreadProcessId((HWND)manejador, &dwProcessID);
HANDLE hProcess=OpenProcess(PROCESS_VM_OPERATION|PROCESS_VM_READ|PROCESS_VM_WRITE,false,dwProcessID);
void* Pointer=VirtualAllocEx(hProcess,NULL,4096,MEM_RESERVE|MEM_COMMIT,PAGE_READWRITE);

RECT bi;
SendMessage((HWND)manejador, TB_GETITEMRECT, indiceBoton, (LPARAM) Pointer);

ReadProcessMemory(hProcess, (Pointer),&bi,sizeof(bi),&nNumberOfBytesRead);

PostMessage((HWND)manejador, WM_LBUTTONDOWN, NULL, MAKELPARAM(bi.left, bi.top));
PostMessage((HWND)manejador, WM_LBUTTONUP, NULL, MAKELPARAM(bi.left, bi.top));
