Re: How to change place of activex control at run time

In a dialog, you can add a control variable to the class just like any other control:

// Add the member to the class declaration
CWMPPlayer4 m_MediaPlayer;
...
// Add this line to DoDataExchange() (where IDC_PLAYER is the ID of the control resource)
DDX_Control(pDX, IDC_PLAYER, m_MediaPlayer);

Then any time after the control is created (after the base class OnInitDialog() has been called)
you can access it like any other window (CWMPPlayer4 is a CWnd-derived class)...

m_MediaPlayer.GetWindowRect(...)
m_MediaPlayer.MoveWindow(...)
etc.

Hi,
Can you please suggest me a way to find out the ID of Back,Finish and Next buttons on the property pages OR to find out the CWnd pointers of those button controls?

Back Button : ID_WIZBACK
Next Button : ID_WIZNEXT
Finish Button : ID_WIZFINISH
then you can use GetDlgItem() to do whatever you want. I hope this helps

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

Also see my reply here[^].

In the sample code I put there, you can add the OnDragEnter()/OnDragLeave() overrides if you need
to respond to those as well.

How to detect which object called the message

Hi everyone,
I am using VC++ 6. I have a 3 listcontrols which display different data. I have customized the list control for the look and feel by creating a class "CCustomListCtrl" .I have created 3 instances of "CCustomListCtrl" in CMainFrame. class which I am using notification message "NM_CLICK" to detect the click on the list. Now i want to identify which of the user has clicked.

There is an NMHDR structure that's given as parameter to the function. It contains a variable called hwndFrom which denotes the control from which the notification came. You can use this handle.

Instead of handling the message in the CCustomListCtrl, handle that message in the CMainFrame itself. NM_CLICK is actually a notification. So handle the WM_NOTIFY message in the CMainFrame and check whether the code is NM_CLICK.

I guess you need to identify the list control which send the NM_CLICK notification message. NM_CLICK notification returns the id and handle to window of list control, this can be used to identify the control.

how to use the handle dude...i tried NMHDR ..it does give different values for the list, but how to identify which value is for what. Well i have to use the custom control for sure, its for different purpose. Also i can't use the click notification in the mainframe since i have listcontrols in different windows

I prefer to use ID than handle but no matters.

You need to store the values of ID when the list control is created and matching the value with which the NMHDR returns identifies the list control.

You can use message handlers in its parent window.

Check if app exists and open from internet

I have a stand alone application (messenger). I was asked to the messenger to have the fallowing possibility:
from a link with a phone number parameter to make a call in the application. If the messenger is not installed, to take the client to the official web site. If the product is installed to see if it is open. If it is open and the user is logged in to make the call.

My idea is the client to check the registry and see if the product is there, which solves the first part. If there are certain keys in the registry next step is from the processes to see if the product is active. If active somehow send instruction to call the function : CallNumber( phonenumber phnum)

Can you give me any leads on how to do all this, any other solution to the task?

The project is done in C++

Thank you very much

hi all
iam facing link error "unresolved externall symboll" while loading my dll explicitly, but it work i load implicitly, here i given the sample by which i tryed, and i defined all the virtual function in the derived class, which in the base class

#include "stdafx.h"
#include "windows.h"
int main(int argc, char* argv[])
{
typedef UINT (CALLBACK* LPFNDLLFUNC1)(DWORD,UINT);

HINSTANCE hDLL; // Handle to DLL
LPFNDLLFUNC1 lpfnDllFunc1; // Function pointer
UINT uParam2, uReturnVal;
DWORD dwParam1;

//HMODULE dll_module = LoadLibrary("./../TestDll/Debug/TestDll.dll");
hDLL = LoadLibrary("./../TestDll/Debug/TestDll.dll");

if (hDLL != NULL)
{
lpfnDllFunc1 = (LPFNDLLFUNC1)GetProcAddress(hDLL,
"MyAbsFunc1");
if (!lpfnDllFunc1)
{
// handle the error
FreeLibrary(hDLL);
return 0;
}
else
{
// call the function
uReturnVal = lpfnDllFunc1(dwParam1, uParam2);
}

return 0;
}

can any one help to solve this link error

you have to specify the lib name in the project setting. or atleat put

#pragma comment(lib, "./../TestDll/Debug/TestDll.lib") in your code.

Hi,

So called "named Mutexes" can be uses between processes. So in this case give the Mutex the name of the File yout are using. But be careful, i think backlashes don't work with mutexes, so you should replace backslashes with some other character.
