Hi all
My task is getting data of UPS using Windows Management Instrumentation(WMI) Win32_UnInterruptedPowerSupply class.
I have tested sample applications using WMI classes like Win32_Process,Win32_OperatingSystem they are working fine.But when iam trying to access Ups data using Win32_UnInterruptedPowerSupply class ,iam notgetting the output. I think there is problem with configuring UPS .
Please suggest and help me in configuring UPS and accessing UPS data.
Thanks

Hi,
I had started a COM DLL project about a year back. When I did a research on DLL back then, I found this is one of the more advance methods of doing it. Before I started the project, I was expecting it to be cross-platform and cross-language but it did not seems to be the case after I finish it. I had managed to get my DLL working for .Net, VB6 (with a bit of difficult for array passing) and VC6++ (which need extensive coding). I am still trying to figure out how to use it in Java.
I am currently wondering if this is the latest way of writing a DLL (I use the ATL COM wizard). I found out that VC6++ also offers MFC DLL and ActiveX ocx. Can anyone tell me what is the different between these 3? It seems that using the OCX method will help with reducing the coding when used in VC6++.
Again my questions are:
1. What is the latest method of writing a DLL?
2. What is the different between creating a DLL/OCX with ATL COM AppWizard, MFC ActiveX Control Wizard and MFC AppWizard?
Any information will be appreicated. As I am very keen in learning more about the technology available.
Thanks in advance.

Try to figure out what you want. DLL and COM have little relationship. DLL is a format of library and COM is a component technology. Almost all Windows libraries are delivered as DLLs, but only small portion of them are COM compoenets. You may create DLLs without knowing COM and COM components can be delivered as DLLs as well.
Do you want to create DLLs or COM components?
Best,
Jun

I know what I want, maybe you should read what I had written again before answering... Pardon me for my rudeness as I do realise that you seems to be very experience... one puzzling issue is that you recent replies do not seems to match your experience.. if fact it seems like an amateur
I said that I had did a COM DLL project, a DLL written in a form of COM component.
Currently what I found out was that written DLL in COM component is one of the latest way of writing a DLL. I just need to if there were any newer way of writing a DLL.

Just tried to help and learn.
I have to disagree that COM is a DLL technology. It's not.

Yes, I do understand that COM is not a DLL technology.
But it can be used to create a DLL and it is one of the more advance method of writing a DLL.
I was just hoping to know if there is any other methods to write a DLL other than this and the older method that exports the function.
I apologise for my rude reply again.

you can have a:
* .lib file which is a static linking library which exports c functions.
* win32 dll which exports c functions.
* mfc extension dll which exports c++ classes.
* com dll which exports ( export is not the right term but exposes)component
classes.
* u can have an ocx which again exports/exposes componentclasses
* u can have a .net managed dll which exports managed types.
All these are valid ways of creating a dll or a dynamic/static linking libraries.'

Hello again,
how can i split CComBSTR Strings?
Example:
<br />
CComBSTR myStr = "iwantto-splitthis";<br />
Is it possible to split it by a special character like - to get two separate strings "iwantto" and "splitthis"?
Maybe I have to convert the CComBSTR to a readable format first.
<br />
LPTSTR myLptStr = new TCHAR[SysStringLen(myStr)];<br />
lstrcpy(myLptStr, OLE2T(myStr));<br />
But then, i still want to split it by - 
Thanks in advance

The code you gave has problems. Firstly SysStringLen does not include an extra count for a NULL terminating character. You allocation should look like this:
LPTSTR myLptStr = new TCHAR[SysStringLen(myStr)+1];

Thanks for the hint, Steve.
Still lost with CComBSTR substr problem

One way:
CComBSTR myStr = L"iwantto-splitthis";
LPCWSTR pBegin = myStr;
LPCWSTR pEnd = pBegin + myStr.Length();
LPCWSTR pBreak = std::find(pBegin, pEnd, L"-");
if (pBreak!=pEnd)
{
CComBSTR FirstBit(pBreak-pBegin, pBegin);
CComBSTR EndBit(pEnd-pBreak-1, pBreak+1);
}</code>
This code assumes you've included <algorithm>
This is probably not the easiest or the best way but it should work (but I haven't tried it!).

Hi,
I managed to get myself started with one of the article in this forum that shows some very easy examples for beginers.
One think about COM is do you want the learn to do the full coding by hand. If that's the case, you may want to read up Essential COM which is highly recommended in this forum. It will show you some of the things that happen in the developement of the COM technology.
If you need to get something up fast, you may want to work with the ATL. There are plenty of articles on using ATL in this forum.

Hi all,
I'm trying to put together a baseline example of integrating an ActiveX control with IE. I've built an MFC ActiveX control from the wizard and modified the OnDraw to draw a black ellipse rather than white.
My HTML looks like this:
<object id="activex"
CLASSID="CLSID:68D632F8-1644-44EA-9C71-725171D59E8E"
CODEBASE="http:AX2.ocx#version=1,0,0,1" height="300" width="300"/>
And the class ID is coming from the idl file:
[ uuid(68D632F8-1644-44EA-9C71-725171D59E8E), version(1.0),
helpfile("AX2.hlp"),
helpstring("AX2 ActiveX Control module"),
control ]
library AX2Lib
Does this look reasonably correct? Are there any references on ActiveX for IE that you'd recommend?

CODEBASE="http:AX2.ocx#version=1,0,0,1"<br />
That http: looks rather odd there.
From the snippet it appears that you might be using the wrong classid. You need to make sure your .rgs file has the proper registration info in it as well.
Any reason you're using MFC and not ATL? Do you need the bloat?

No, it was just a "start here and see what happens" attempt. You're the second person to recommend ATL, so, I'll investigate that next.

ATL is in my opinion a lot smarter for doing ActiveX stuff. Will you be creating windowed or window-less controls? If you are going to create windowed ActiveX controls, I really do recommend that you add some WTL to reduce the Win32-ish coding.
If you are going to create window-less controls, the ATL wizard will put you on the right track.
BTW, to reduce compilation times, you may want to drop the "attributed" stuff. If you use the attribute-stuff (looks like .NET-attributes), the compiler will recompile the "hidden" IDL file everytime you recompile. If it's a small project, it will double the compilation times.

When I deployed an activex over the web, which I've really only done once, I made a .cab file with the .ocx, other support files and an .inf that contained all the installation info (default registry settings, etc).
The coolest part was that all I had to do was change the FileVersion # in both the .inf and html, then recreate the .cab and the .ocx would be automatically updated the next time people visited the site.
This is the html:
<OBJECT ID="MyOcxID"
CLASSID="CLSID:68D632F8-1644-44EA-9C71-725171D59E8E"
CODEBASE="MyCabFile.CAB#version=1,0,0,1">
</OBJECT>

As far as technology is concerned:
if performance is what u r looking for, ofcourse ATL,WTL is the choice.
if development time and developers are the concern then VB6 is better, or even you can go for .Net controls with interop.
Regarding the code:
If you are using the html on a local computer, then u dont need to specify CODEBASE attribute. ie you can open the html by typing c:\axdemo\ax.htm in the explorer address bar without that CODEBASE attribute.
But if you need to acess it over http then you have to specify the CODEBASE atribute. either this can be a direct http based url to the ocx or it can be a .cab file to reduce download time.
download Activex Ccontrol Pad[^] from micorsoft for generating the html. They will do everything.

Hi all,
i am about to write a BHO for an e-learing application. What I need is a non-blocking Timer for the Refresh of the browser. How could i use a timer to refresh every 5min or so without blocking the Browser Window...?
Still haven't got Scott Roberts famous book about IE Programming.
Thanks for your help
