Skype application would provide some interface to do that - possibly like some COM interface that client applications can use. http://developer.skype.com/[^] might help.

Hi
I have a web application that generates a HTML document. I need to export it to Word and Outlook and add an image logo in the top corner, but come across problems in both exports.
Creating a *.msg is fairly easy, as it accepts HTML as body of the message, but I don't know how to add the image. Can I simply add it as an attachment and reference to it in the HTML (I've seen it done this with the .NET class MailMessage)? Also, I know that when the application is run outside the development envirement (stand-alone on IIS), it will be denied access to the Outlook Library - is there a workaround for this, or is it simply not possible to use this library on server side?
As for Word document - I managed to fix the image where it's supposed to be, but I don't know how to insert the HTML, as every solution I found on Google ended up displaying the HTML tags, rather that interpreting them.
Or is there another way to do this? I tried to create an *.eml file and save it as *.doc, but some of HTML parameters (ie width) are messed up when I open the file in Word.
Thanks in advance

Frustrated by the process of debugging a COM Automation client over ADO and MSHTML in native Visual C++, I've devised COMWatch - a debugger visualizer for COM objects under native VC++. With COMWatch in place, one can see the contents (i. e. properties and collections) of your typical IDispatch-based object right in the Watch window, like the VB folks are used to. You can see the full object's content or drill down to a specific member, no matter how deep down the object hierachy.
COMWatch works by injecting some code in the project that would dump the object contents in the way the debugger can display it in the proper tree-like format. Given the call-driven nature of Automation, there's no good way to make visualization logic completely debugger-based.
COMWatch is free; you can grab it at http://sevaa.home.sprynet.com/comwatch/ . Enjoy.
Visual Studio .NET 2005 only.

Hey guys,
I'm having a very strange problem with my windows service and a COM component. I have a wrapper class (which is a user control) that instantiates the OCX and adds some functionality (reverse geocoding) to it. If I instantiate the wrapper class during the OnStart event of the windows service, everything works fine. But, if I create a new instance of the wrapper class outside of this event (after the service has started), the services freezes at the line
((System.ComponentModel.ISupportInitialize)(this.axMapPro1)).EndInit();. The wrapper class works perfectly in my windows forms application.
I have no idea what could be causing this, as I'm not an expert on COM interoperability. Any of you geniouses out there have any bright ideas?

If its VB.NET code, try adding DoEvent before ((System.ComponentModel.ISupportInitialize)(this.axMapPro1)).EndInit()

It is C# code - what is DoEvent?

I tried calling System.Windows.Forms.Application.DoEvents() before I call EndInit(), but am still experiencing the same problem. Any other ideas?
|

Try a loop.
Do<br />
Application.DoEvents()<br />
Loop Until < timedelay >
Try experimenting with TimeDelay and see if this fixes your problem.
Also attach a debugger and see where it hangs.
What OS are you using?

I am facing a problem in calling CreateDisptach for any Class ID
Here's a brief summary of wat m trying to do
I create classes from a type library.... by using ClassWizard in VC++6.0 ,say of Excel, using the Excel.odl/Excel.exe file(2002 onwards)...
Now I get a class _Application....then I hve the following very simple code:
_Application app; // app is the Excel _Application object
if(!app.CreateDispatch("Excel.Application"))
{
AfxMessageBox("Error creating Dispatch");
}
Now...the program fails on this CreateDispatch always for any prog ID ..even if its not "Excel.Application".... Inside the 'CreateDispatch' function....the 'CoCreateInstance' function returns 'REGDB_E_CLASSNOTREG' as an error....
If I create the same automation object using VB then it works fine...also the same VC++ code works on any other mahcine...
I've called AfxOleInit() in InitInstance() ...its a dialog based mfc app
So I need help here... Wat is causing the code to fail on my machine ??
Thanks in advance

Is the code working(when placed in other application) or the application itself is working on other machine?

Check your registry for Excel.Application prog id and the corresponding CLSID.

If the same application is running on other machines then I would look at the machine that has problem. your statement makes me believe that the source is correct and there is some problem in the machine config. Or it could be that the ProgId-CLSID problem
Compare the CLSIDs (corresponding to ProgId) that are being picked by your C++ app and from VB app.
Following link from Microsoft support will helpHow To Call CLSID And ProgID Related COM APIs in Visual Basic[^]

I am quite new to COM and such, and I am hoping some folks would know the answers:
1) does VariantClear free the emmory associated to arrays if the arrays are not locked to be specific:
[code]
//code to allocate an fill mySafeArray...
VariantInit(&myVariant);
myVariant.vt = VT_VARIANT | VT_ARRAY;
V_ARRAY(&myVariant)=mySafeArray;
//some COM call that uses myVariant
//free the contents of myVariant.
VariantClear(&myVariant);
[/code]
would this leak? as I am not explicitly freeing the SAFEARRAY, but the description from MSDN (http://msdn2.microsoft.com/en-us/library/ms221165.aspx) says it will free the contents of the SafeArray, but the examples I have seen for this COM API I am using all free the array by hand and then clear the variant so what is supposed to be done?

We have our current Web applications designed in ASP.We are planning to migrate this to .NET. Our applications interact with a lot of COM components hosted on MTS.We are planning to migrate all these applications along with the COM component to .NET,i.e., all ASP pages to ASPX and all COM components will be re written into .NET dlls. Okay so far so good.
As a part of our investigations, we are trying to come out with the best possible "replacement" for COM/MTS in .NET. We have thought of 3 techniques:
a.Put all the .net dlls(i.e., COM converted to .NET dlls) into a common folder and and refer them from our Web applications
b.Using .NET remoting: Hosting every .NET dll as a remotable object using a windows service.Our Web applications can consume this remotable object.
c.Using Reflection techniques: By Runtime binding them from Web applications
(Please Note: We do not want to look at Web Services as an option currently)
Can anyone let us know which among the 3 is the best option for converting COM to .NET equivalent(OR is there any other better method )
|

We are also currently looking at different options for our midlle tier, ideally we wanted to host inside COM+ which meant making use of .net enterprise services. Unfortunately the imposing com and com+ rules on our .net application is just not practical. We will now use WCF which effectively is remoting but properly layered where you can choose hosting environment and communication protocol.

Hai,
I am using two COM server Exe's with MFC support.
In my working environment a MFC application will call the COM interface of my COM server 1.
And my COM server 1 calls the interface of my COM server 2( This application has a window ).
On entering the interface call of COM server 2, i had logged that information into a file.
I had also logged the information while exiting that interface call from COM server 2.
In COM server 1, I had put a log just after this interface call (Interface call to COM server 2 )
Issue :- While analysing the log i had found that the interface call of COM server 2 is returned ( By analysing the IN and OUT log that is logged in COM server 2 ). But the log i had put in COM server 1 just after this interface call is not logged. But if I clicked on the window of COM server 2 or MFC application. The log that is put after the interface log is logged.
Can anybody help me?
Regards,
appoos

Are you sure that the log function you use on COM server one produces instant results? It's a common practice to just store information untill the right occasion comes up to complete the write. I would also look at how the call between the COM servers works. Their might be some problem in that.

I'm totally new to ActiveX and don't know where to get started.  Hoping you can help.
My plan is to develop an ActiveX component (MSVC++) for the purpose of being used by IE. I need the ActiveX component to store information in persistent storage.
I have a bunch of HTML + JS that currently uses a signed Java applet for reading/writing files to the hard disc.
I would like to remove my applet in favour of ActiveX.
Anyone got pointers to sample sources and good guide to storing persistent data from ActiveX.
Lastly, when searching around the net I can't find a great deal of useful ActiveX stuff. Is ActiveX more commonly referred to as something else?
Appreciate any help you can offer. TIA.

Why do you want to do that? The signed java applet looks like a more appropriate tool to me.
