Hi all,
I have made an Internet Explorer toolbar. ToolBar is having only three buttons. I used TBBUTTON for making Buttons. I have loaded bitmaps on each button using following code.
myfun(){
CToolBarCtrl::Create(DEFAULT_TOOLBAR_STYLE, rcClP, pWndParent,IDB_BITMAP1))
AddBitmap(3, IDB_BITMAP1
TBBUTTON tbs[3];
for (int i = 0; i < 3; i++)
{
tbs[i].dwData = 0;
tbs[i].fsState = TBSTATE_ELLIPSES|TBSTATE_ENABLED ;
tbs[i].fsStyle = TBSTYLE_BUTTON;
tbs[i].iBitmap = i;
tbs[i].idCommand = ID_BUTTON1 + i;
tbs[i].iString = i;
}
AddStrings(_T(" Red\0"));
AddStrings(_T(" Green\0"));
AddStrings(_T(" Blue\0"));
if (!AddButtons(3, tbs))
return false;
return true;
} //function ends here
Here I am able to load bitmap on each buttons . But I need to add Icons on each button. How it possible
Please Help me
Thanks in Advance

I don't know for sure, this question should be in the Visual C++ / MFC[^] forum to get more eyes on it. You might have to create your own image list and load the icon into it then set the image list TB_SETIMAGELIST into the toolbar control. See Toolbar Controls Overview[^] for more information.

I have used new ATL object to do OLE DB connection,bywhich i got table.h header file,and now i want to insert data in msaccess table by using following code...can anybody help me to solve my problem can you just tell me one thing first whether this way of using to insert data is correct or not...
and what changes should i make it here to correct it
.

For that toolbar, how should I provide Tooltip?
Thanks in advance.

regsvr32 <path to="" plugin="">
should suffice
use
regsvr32/u <path to="" plugin=""> to unregister it

Does anyone know why CoCreateInstance for IShellWindows fails if called by an IE extension running in windows service?
Code for creating service:
SC_HANDLE hSCM = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS);
if (!hSCM)
{
WriteMainLog(_T("INSTALL: OpenSCManager error."));
return FALSE;
}
SC_HANDLE hService = ::CreateService(hSCM,
SERVICE_STR_ID,
SERVICE_STR_ID,
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS |
SERVICE_INTERACTIVE_PROCESS,
SERVICE_AUTO_START, // start condition
SERVICE_ERROR_NORMAL,
gszFileNewPath,
NULL,
NULL,
NULL,
NULL,
NULL);
if( !hService )
{
WriteMainLog(_T("INSTALL: CreateService error."));
return FALSE;
}
....
hr = CoCreateInstance(__uuidof(SHDocVw::ShellWindows),
NULL,
CLSCTX_ALL,
IID_IShellWindows,
(void**)&spShWin);
if( FAILED( hr ) )
{
_com_error er(hr);
_stprintf(err, _T("[MTProcessesInfo::GetURLInformation]. spShWin.CoCreateInstance. %s\r\n"), er.ErrorMessage());
WriteSpyLog(err);
return FALSE;
}
Error: "Class isn't registered".

Didn't you like my answer in the other thread you started for this ?
Try This First
at least try what I suggested first before reposting on a different board.
anyway this is a COM question, not an ATL/STL or WTL one.

Hi
Question 1:
When we create an COM object in a Process where does the memory of the COM objects get allocated?
Question 2:
Does the memory allocated to the COM object contributed to increase in Virtual memory of the process where it is instantiated.?
Question 3:
What is the relation between virtual memory of a process and private bytes of the process?

When we create a COM Object in a Process memory of the COM Objects get allocated in 'Heap Portion' allocated to the process.
And yes memory allocated to the COM Object contributes to increase in virtual memory of the process.
And regarding third question, actullay I could understand what you are trying to ask? Can you please clarify 'private bytes' of the process.
Thanks,
Suraj

IElementBehaviorFactory* pEBFactory = NULL;
//Create my com object of implementing IElementBehaviorFactory interface
CoCreateInstance(CLSID_Factory, NULL, CLSCTX_INPROC_SERVER,IID_IElementBehaviorFactory, (void**)&pEBFactory);
//Mashal IElementBehaviorFactory
hr = CoMarshalInterThreadInterfaceInStream(IID_IElementBehaviorFactory, pEBFactory, &pStm);
The return value hr is 0x80004002, why?
The default value of [HKEY_CLASSES_ROOT/Interface/{3050F429-98B5-11CF-BB82-00AA00BDCE0B}/ProxyStubClsid32] is {B8DA6310-E19B-11D0-933C-00A0C90DCAA9}.
{B8DA6310-E19B-11D0-933C-00A0C90DCAA9} is the class id of actxprxy.dll.
I think that actxprxy.dll is the proxy/stub for IElementBehaviorFactory, but I don't know why CoMarshalInterThreadInterfaceInStream call fail for IElementBehaviorFactory.

We have a function which has the following signature
SomeFunction(TCHAR* szPassword,TCHAR* szEncryptPwd)
Now we need to pass in a std::string as the first parameter,and convert the second parameter back into a std::string on return.
How is the conversion from std::string to TCHAR* and back to std::string done?

Hi. I'm new to writing Active-X controls and have a few quesitons which I couldn't find answers for in the archives. Here's what I'm trying to do. If you have a better suggestion, please respond.
We are using Visual C++ 6.0 and EVC++ 4.0 and ATL (no MFC). I want to create a collection of ActiveX controls which will all be derived from one base control so I can use a vector of them in a container window. My main quesiton:
- Is it even possible to derive new ATL ActiveX controls from a base ATL ActiveX control? I'm thinking like in regultar C++ if I create a base ActiveX control for, say, a button, then derive other types of buttons from that and override their OnDraw() or OnPain() methods, I can just have a vector of these base buttons. Am I off in left field?
Thanks,
Mark.

More like left-center.
No you cannot derive from ActiveX controls because you cannot derive from COM objects.

For what purpose is the vector? Not to use the OnDraw() or OnPaint() methods right? All COM objects already share a common interface "IUnkown", so technically you could store that in the vector, but for what purpose?

The idea was to have a container window class of some sort which would contain any number of ActiveX controls. These would be diverse (buttons, grids, graphs, etc.). I figured a vector could contain maybe pointers to these, but in my non-COM object oriented brain I'm thinking they all need to derive from some common class, then. Each one would handle it's own drawing and functionality.
Our current design uses a template struct, "ViewHost", which contains a CAxWindow and a CComPtr member. This struct wraps the creation of the ActiveX controls. Our current design hard-codes different container window types to contain specific ActiveX controls. I'm working on redisigning it and want to be able to take any container window and put whatever controls I want in it. My thought was a vector of our "ViewHosts" in each container, but since ViewHost is a template (and since it contains CComPtr which is a template), the compiler needs to know at compile time what class each one is. So that kills my idea of a vector of ViewHost structures containing any kind of ActiveX control.
Anyhow, that's why I thought "if I can derive these controls from some common base class I can have a vector of them"
Any thoughts? Are you sure I'm only "off center"?

CAxWindow already does that so I am completely confused at this point.

Hm.... I need to look at our design. The guy who did the design is no longer here. One thing we've done is create our own private heap class. It's very likely he wrapped this code to make use of our own New and Delete methods in our private heap.
So you're saying a guy could have a vector of any number of CAxWindow's and be good to go?
(sorry for the ignorance -- I'm not all that adept at ActiveX and COM)

Well not yet since you still did not explain "why" you need anything in a vector. So far all you mentioned was the painting routines which are already managed from a calling stand point so there would be no need for you to access any of these objects at runtime in association with painting.

Sorry. The ActiveX controls have methods that need to be called on them. Obviously things like painting happen already. These controls are things like real-time graphs (strip charts) for instance, which have data sent to them, status information, etc. There are numeric displays that a user might interact with via touch-screen, which might visibly change based on user input. We're using a "Model/View/Controler" pattern, and the "View" part of that will contain the ActiveX controls for user input and display of information. The Model and Controller (also COM objects) process user input events from the View and change the display of the ActiveX controls where needed.
So I need some way for the Model to manage the View. Since the View is a container of ActiveX controls, the Model needs access to these to update them and make visual changes via calling methods on them. If a View container can have any number of diverse ActiveX control on it, I thought a vector would be a good route.
Our current design has specific View containers pre-defined. It's a very non-flexible design. One pre-defined view might always have 3 buttons along the top, so there are 3 "ViewHost" members containing buttons. It may always have a static text box, so there's one "ViewHost" member for that. When the user touches the button, maybe the next step is for the other two buttons to dissapear and the text to change. The Model needs to have access to the View's ActiveX controls to tell the 2 buttons to make themselves invisible, and push some text into the text box.
Hope that makes it clearer.
Mark.

MVC pattern should utilize "events" to notify listeners of data changes. Then listeners "pull" data. This way the Model remains isolated from knowing about Controllers or Views. This is a major factor in the MVC design.
In your case it sounds like your View windows (the containers of all the CAxWindows) might be good candidates for registering for the data events. Then each View would have the logic about how to call methods in all it's child windows to update their displays.
Does that help?
