Active X components are basically COM components.
So you can create an instance of it and then use the control in your application.

That's a but simplistic. An ActiveX control is a COM object but writing code to correctly host it is far from trivial: in fact it's hard. The easiest way is to use MFC's or ATL's hosting code.

Check the locale of your PC from the Control Panel, Region and Language link.
I must get a clever new signature for 2011.

If you have RTTI enabled (which it is by default) you can use dynamic_cast to check.
dynamic_cast will check the type information and only succeed if it is a valid operation, otherwise return NULL, so to see if a variable is of a type:
if (dynamic_cast<CMyFormView *>(m_pWnd) != NULL) {
} else if (dynamic_cast<CMyTreeView *>(m_pWnd) != NULL) {
}
alternativley, if you are using DECLARE_DYNAMIC or DECLARE_DYNCREATE in your class definitions (should be using DECLARE_DYNCREATE to use it in a spitter if i remember correctly) then you can also check the type information with
if (m_pWnd->GetRuntimeClass() == CMyFormView::GetThisClass()) {
} else if (m_pWnd->GetRuntimeClass() == CMyTreeView::GetThisClass()) {
}

That code was from a project made in Visual Studio 9.0 (2008).
The function may have a different name on your version of visual studio, or you may not be using the DECLARE_DYNAMIC or DECLARE_DYNCREATE.
If you are using 1 of the mentioned macros try checking the definition of them to see if the function has a different name. you are looking for a public static function that has the same return type as GetRuntimeClass(), probably CRuntimeClass*.
Otherwise you can just use the dynamic_cast method I described

Is that possible or all modules should be of the same architecture?
Dll is loaded with LoadLibrary and a function is called.

Well, up until a few days ago I thought it was impossible, but I noticed that occasionally x64 version of NTDLL was loading the x86 version of NTDLL into a x64 program.
I don't know how it is done, perhaps 1 of the many undocumented APIs.
In the past I have created a x86 helper .exe which loads the DLL, and returns whatever. This can be done with Remote Procedure Call, but I only ever used pipes.
EDIT: It may be loading them for resources rather than code with LoadLibraryEx, which should be allowed

Hi
i am beginner of win32 Vc++. I create Menu item and call File open dialog box. I have a File Menu. it contains Open, save and exit menu items.I have file open dialog box function. Open menu item id is: ID_FILE_OPEN.
my code like
case WM_COMMAND:
switch(wParam)
{
case IDOK:
EndDialog(hWndDlg, 0);
return TRUE;
case IDCANCEL:
EndDialog(hWndDlg, 0);
return TRUE;
case ID_FILE_OPEN:
OnFileOpen(hWnd, ID_FILE_NEW, 0, 0);
break;
}
But error is come like ID_FILE_OPEN' : undeclared identifier
how to fix this?
Regards,
M.Mathivanan

In your menu in the Resources window you will have specified a value for the menu item File>Open. You can find this value in the properties window (View->Other Windows->Properties Window) and click on the Open item in the file menu in the resource editor.
The value will also be #define'd in the Resource.h file, so be sure to #include "Resource.h"

When we press Shift+Delete key, a delete confirmation dialog is generated. I want to handle this dialog according my need or change its message. Can anyone tell me what thing is responsible for that dialog?
I either need to know the code which handles the delete confirmation dialog generated by the Shift+Delete key sequence in Windows XP, or the code by which we can control this operation.

|
|
Take a look at Classic Shell[^]
It replaces the Copy dialog, surely the same principal can be applied to delete

Well, firstly you would need to decode the MP3 data. No point reinventing the wheel, just use something like LAME[^]
Then you need to draw it to the screen somehow. If you are using Windows, I might suggest GDI+[^]
The scope is the most basic audio analysis visual to make... all you are essentially doing is displaying the value of the data at each sample, so just draw it like a massive line graph mapping sample number vs. sample value

For the plotting part, there's a couple of chart controls on CP. You can also have a look at my sig for one of them that I developed.

Hi,
I deveopled a MFC appliocation using visual studio 2008. It is running fine on double clicking the exe but If I launch the same application using installer (install shield) it is not lanching and producing a exception.
What might be the cause?
|
|
|
|
|
Perhaps an exception code, minidump, memory snapshot, anything could help, attatch the visual studio debugger as a JIT debugger.
