hi when iam tryig to acquire UPS data using WIN32_UninterruptiblePowerSupply class of WMI ,iam not able to get the output,and i have searched on net for the solution , what i found is

Most UPS's now days disable native OS support when they install, because
they want to use their agent program instead. A good example is APC. So if
your using an APC by default it turns off UPS support (Maybe MS needs to
beef up the UPS support so APC doesnt feel they need to do this for
functionality). So in this case WMI wont be any help. But IF your UPS uses
the built in UPS support Windows provides then you should be ok

can u please elaborate on this and tell me how to get UPS data.

Thanks in Advance

Hi all,

I would like to ask if anybody is knowledgeable in service objects? Can anyone recommend a site or provide me with documentation for me to understand more about service and control objects?

Hi,

Can I write a shell extension which can process my own shell format?
For example: I have an application which has own data format, and when
drag from this applicaion and drop on explorer, the extension can process this data format.

It's like when you drag some texts and drop on explorer, which generate some special file.

Of course, I want generate my own files.
Anyone can help me?

The most common format for the explorer is the combination of RegisterClipboardFormat(CFSTR_FILECONTENTS) and RegisterClipboardFormat(CFSTR_FILEDESCRIPTOR). These formats tells the explorer what filename to use and to render data from a storage (IStream). The IStream can render any data-format you want. For small data you can also use a HGLOBAL memory block to render your data-format.
To realize this - you have to implement your own IDataObject at least.

SIMPLE COM DLL WITH MULTI RETURN VALUES!!!

hy everybody,

i really have a strange problem, and i hope that this very nice forum can help me out another time.

So what i have is a very simple com dll, if followed this article to build it: COM-DLL

my prroblem is, when e have a function like this:
[id(5), helpstring("method test2")] HRESULT test2([out,retval] BSTR* str);

i want to return more Parameters with the [out,retval], not only a BSTR* maybe a sequence or an array would be nice! In my Project i have to return 20 Strings to the Client who is using this dll, how does this work?
maybe something like this:
[id(5), helpstring("method test2")] HRESULT test2([out,retval] BSTR* str[20]);

I dont know or passing a sequence or an struct as a return Parameter?
Or what about this VARIANT* Types how does this work?
[id(5), helpstring("method test2")] HRESULT test2([out,retval] VARIANT* );

Please could someone explain it to me, i really need this asap...
Really, thank you in advance,

You could describe a structure in IDL and use that as an out parameter.

Yeah that was my idea too, but how could i do this, i try it that way:

interface Idatamng : IDispatch{<br />
struct PM<br />
{<br />
BSTR var1;<br />
BSTR var2;<br />
}<br />
[id(1), helpstring("method get_orderids")] HRESULT get_orderids([out,retval] PM* pm_inst1);	<br />
};

But this is not working! Also with an Typedef it is not working:

interface Idatamng : IDispatch{<br />
struct PM<br />
{<br />
BSTR var1;<br />
BSTR var2;<br />
}<br />
typedef PM pm_def<br />
[id(1), helpstring("method get_orderids")] HRESULT get_orderids([out,retval] pm_def* pm_inst1);	<br />
};

So i dont know how to build a structure in IDL, could you help me please!

Ok something has changed and a new error occured ok the following is working, it is compiling, that should be the right description:

<br />
interface Idatamng : IDispatch{<br />
	<br />
	typedef struct _MYPM<br />
	{<br />
		BSTR id1;<br />
		BSTR id2;<br />
	}MYPM;<br />
<br />
[id(6), helpstring("method test3")] HRESULT test3([out,retval] MYPM* peter);<br />
};<br />

This is the code from the idl file, and he compile it!
But now i try to access the struct from the cpp file of the class:

<br />
STDMETHODIMP Cdatamng::test3(MYPM* peter)<br />
{<br />
	<br />
	AFX_MANAGE_STATE(AfxGetStaticModuleState());<br />
<br />
	// TODO: Add your implementation code here<br />
<br />
	peter->id1 = CComBSTR("Test");<br />
	return S_OK;<br />
}<br />

if peter->id1 = CComBSTR("Test"); a constant string everything is fine, test it with a small vb app it gave me the string back to the client, but if i try to hold this parameter flexible by an variable of the class, for example orderid which is an array it fails:

<br />
STDMETHODIMP Cdatamng::test3(MYPM* peter)<br />
{<br />
	<br />
	AFX_MANAGE_STATE(AfxGetStaticModuleState());<br />
<br />
	// TODO: Add your implementation code here<br />
<br />
	peter->id1 = orderid[0];<br />
	return S_OK;<br />
}<br />

So the vb test app, returns a System.NullReference!
I dont know why he is not able to get the string back from the DLL.
I hope someone can help me on this topic!

Thanks for everything Smile | :)

DirectX movie play from URL

id1 is a raw BSTR, you can't just copy it using =. Try Something like this:

peter->id1 = SysAllocString(orderid[0]);

Hooking into IE

I have a problem that I'm trying to solve in the best possible way (arent we all;).

I am trying to make a browser extension in the form of a DLL that will automatically load with IE. Currently I have a solution in the form of an exe that, when run, loads IE instead of vice versa. Doing it this way I have complete control over IE, which is what my goal is.
However, I am wondering if it is possible (so far from what I've found it doesnt appear to be), to make a library that IE will load when IE itself is loaded. This library will then capture that instance of IE's process/handles/etc and capture the browsers events so the library can control the behaviour of the browser, and just "do stuff" in general on IE events. Using IWebBrowser2, DWebBrowserEvents, and all those good COM interfaces/objects, I already have it all working but only as a seperate exe process that I have to manually start-up.

Is this doable?
Are there registry keys you can enter in to make certain libraries load with IE? I know google toolbar loads up from a single DLL file. However I'm not sure if the DLL is actually loaded at IE startup or if its the standard "click a button on the toolbar to trigger a function in the DLL" (which, is easy to do). The toolbar itself is just a visual manipulation, making that visual representation of the toolbar is just a few registry keys really, which dont really do anything, they just point to a place (the DLL) that does. Like shortcuts to programs on the desktop.

Thanks in advance for any feedback or thoughts on this.

Take a look at Browser Helper Objects. These are loaded into IE when it starts up. There are many examples of customizing IE here on Code Project.
