Hello,
I’ve developed ATL Control using VC++ 2003 to use it as GUI component for different programming environments. It works fine with .NET and Borland builder, but when I try to use it with VB6 or VC++6 I got ‘Permission denied’ error. It happened when I call ::GetClientRect(m_hWnd, &ClientRect) function, where m_hWnd is a private member of this control (handle of control’s window). What’s wrong? How to fix it?
Regards,
Leonid

Hello,
You need to use BSTR as argument’s type for COM server. Interop takes care about the rest.

Hello,
here is a function's signatures for 2 PowerPoint effects event handlers:
SlideShowNextClick(SlideShowWindow Wn,Effect ef)
The effect onNextClick is ef.
SlideShowNextBuild(SlideShowWindow Wn)
What is a current executed effect??
At the moment I have next implementation:
1. By handle SlideShowNextClick store next effect name ("xyz").
2. By handle SlideShowNextBuild execute my bussiness logic (for effect "xyz").
The problem occurs if the current slide has more than 1 effect on page and "go back" button will be used. ==> I can't catch "goback"-event, thus I can't be sure that my stored "NextEffect" is a next effect realy.
Is it possible to get number/name of current executed effect directly in SlideShowNextBuild handler?
Many thanks for your help.

I have an encrypted string like one below
óðØÐÕ“Ðí¼Q‰ð¿GäšÉ²xq¯‡#D
Ù(=×-Åñׇòu𞇩5O™ß½õXê&g"²Áy;‹í
"qÃgø)tý)KŽTÄbÀ Asï°ªñ5g3C`èì^Þn|qt†ò4²{q`Bòåm…
i want to pass this to an ATL com component from asp and save the same thing in a text file from the component
i put this entire string in an array as below in vbscript
myData = óðØÐÕ“Ðí¼Q‰ð¿GäšÉ²xq¯‡#D
Ù(=×-Åñׇòu𞇩5O™ß½õXê&g"²Áy;‹í
"qÃgø)tý)KŽTÄbÀ Asï°ªñ5g3C`èì^Þn|qt†ò4²{q`Bòåm…
Redim BinArray(LenB(myData))
For I = 1 To LenB(myData)
BinArray(I-1)=MidB(myData, I, 1)
Next
i am passing to com component with the statement
dllObj.ProcessData(BinArray)
dllObj is com component
Method inside the component is
STDMETHODIMP CKey::ProcessData(VARIANT *data, BSTR *success)
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
HRESULT hr;
_variant_t vtArray (data);
VARTYPE vt = V_VT(&vtArray);
if (vt & VT_ARRAY)
{
long lLBound, lUBound;
SAFEARRAY * psa;
// copy variant array to SAFEARRAY
SafeArrayCopy(*(vtArray.pparray), &psa);
SafeArrayGetLBound(psa, 1, &lLBound);
SafeArrayGetUBound(psa, 1, &lUBound);
for (long loopCnt = lLBound; loopCnt
|

|

Argument in .idl should be like this: [in,out] SAFEARRAY(BYTE)* pData. In .h and .cpp it should be: SAFEARRAY** pData.

Added the DLL as a reference.
I cant see the control on the tool box.
Forgive me, I'm totally new

Hi I am a newbie with COM & ActiveX and would like to ask for some advice.
I'm developing a GUI for real time systems, written in ANSI C and C++, it will provide drawing functions, a windowing system, widgets, bitmaps etc.
I want to add a possibility to use it aswell as an ActiveX control, so people can create a VisualC++ project and develop on it as a way of simulating the real hardware. So the ActiveX control should display what at the end will be seen in a real screen running the GUI in an embedded real time system.
Any hints on the best way to do this? I am just starting my research on ActiveX possibilities. My first thought is to use an ActiveX dialog with a picture control on it the size of the real screen. Then make it get the picture content from a memory area provided by the container application. When the container changes that memory, changes should be displayed in the ActiveX picture. Should the picture control be a bitmap or a "owner draw" type? Any help will be much appreciated.
Thanx!!

Hi~
I am programming a customized web browser with IWebBrowser2 in windows ce 5.0
And I want to embody some functions which copy/cut/paste.
I made it in Win32 Application already..
Using by these ways
Way1
HRESULT hr = m_pWeb->ExecWB(
OLECMDID_COPY, OLECMDEXECOPT_DODEFAULT, NULL, NULL);
if (FAILED(hr))
{
int n = GetLastError();
ASSERT(false);
}
Way2
IHTMLDocument2 *pHtmlDoc;
hr = pDispatch->QueryInterface<ihtmldocument2>(&pHtmlDoc);
EHResult::CheckException(
L"CMainFrame.Copy.QueryInterface<ihtmldocument2> Fail (0x%08x)", hr);
IHTMLSelectionObject *pHtmlObj;
hr = pHtmlDoc->get_selection(&pHtmlObj);
EHResult::CheckException(L"CMainFrame.Copy.get_selection Fail (0x%08x)", hr);
{
IDispatch *pRange;
hr = pHtmlObj->createRange(&pRange);
EHResult::CheckException(L"CMainFrame.Copy.createRange Fail (0x%08x)", hr);
IHTMLTxtRange *pText;
hr = pRange->QueryInterface<ihtmltxtrange>(&pText);
EHResult::CheckException(
L"CMainFrame.Copy.QueryInterface<ihtmltxtrange> Fail (0x%08x)", hr);
VARIANT null;
VariantInit(&null);
VARIANT_BOOL isOk;
hr = pText->execCommand(L"Copy", VARIANT_FALSE, null, &isOk);
EHResult::CheckException(L"CMainFrame.Copy.execCommand Fail (0x%08x)", hr);
}
But It doesn't work in windows ce 5.0 -0-
What should I do now~
And I have one more trouble.
I have to control the element's focus (in html document like ANCHORs or
CONTROLs) by arrow key.
Is there a way get the current focus of elements??
It also possible to get in Win32 by pHtmlDoc->get_activeElement
But Win CE 5.0 -0-
Please Help me~
Thank you.

I have a .lib generated in VC6. How can i create a COM wrapper for this lib( with some related .h files), which can be used within a VC8 application. Since i am not much aware of COM wrapper,please help me with some details....

If you want to access the exported methods from Managed C++ then I beleive you may want to look at Interoperability topic in .NET.
Following may be helpful, if you require a COM wrapper over existing DLL -
1. Create a new ATL COM DLL project
2. Add a simple ATL object
3. Add methods [and properties, if required] to the interface of this object. These methods [and properties] correspond to the methods in your DLL. You have the declaration in the .H file already
4. Implement these methods [and properties]. Usually you will only call the exported function of your DLL from each method.
Let me know if this helps. Anyone who knows more specific or can correct me, please do.

How would I distinguish between a normal COM component and an ActiveX control by looking at the code?

From MDSN:
At a higher level, an ActiveX control is a COM object that implements several main ActiveX technologies, including regular incoming COM interfaces, the OLE embedding protocol, connection points, and property pages. At a lower programmatic level, ActiveX controls are just COM classes implementing certain families of interfaces. When some client code successfully queries for one of these interfaces, the client code then knows it's dealing with an ActiveX control.
The interfaces exposed by an ActiveX control fall into three general categories. First, ActiveX controls are embeddable objects; that is, they implement most of the OLE Document in-place activation and embedding protocols. ActiveX controls implement the following interfaces: IOleObject, IPersistStorage, IDataObject, IOleInPlaceActiveObject, IOleInPlaceObject, IViewObject2, and IRunnableObject (this is rarely used). Second, ActiveX controls usually support property pages so the client has a means of modifying the control's properties. Finally, ActiveX controls usually implement outgoing interfaces that the client can find out about using COM's connection point technology.
So basically you can determine if it's an ActiveX control by what interfaces it's exposing and whether it has a property page or not.
I got the text from this article[^].

Nah, you've got to know what to look for as well.
I knew you can tell from the interfaces, but couldn't remember them, and I wanted some writings to refer to.
No worries, mate!
