Hi,
I want to create a phone number control. It has text boxes for a USPhone number, an international phone number and international country code. I want it to display the USPhone field and d so in a formatted manner. If the record's Country is blank or "US" or "Canada"...
I think I can create the control. Will I be able to import it into Access and use it on a form that is bound to a table, such that I can bind this control to several fields in the table?
Thanks!

Hi,
I am trying to use the Visual SourceSafe 2005 SSAPI.DLL in a simple Windows application (C++), but I can't get around an error that indicates that the classes of the DLL are not registered. I have manually registered the DLL using the REGSVR32 utility, but I still get the error.
Any help greatly appreciated.

Is Visual Source safe registered on your machine? If this is the case then, it is possible the construction of CoClass fails resulting CoCreateInstance returning Class not registered error.

I'm missing the OLE Container control from VB6 so ny question is
Is it possible to build a Com component which acts as an OLE container control for one specific COM EXE server?
It should provide a window for InPlaceActivation of the specific server, for example Microsoft Equation Editor.
Thankx in advance

Once I click the receive button twice, accidentally, the NULL modem program running between two PCs is hung !!
How can I detect the data is received so that I can read the data without hanging the COM program written in C# Visual Studio .Net.
Any one can help.
Thank you

I have a COM collection object that maintains two STL containers. While it is unlikely, it is possible that an exception will be thrown while the containers are out of sync. In a normal application, I would simply abort under those conditions. What should an in process COM server do if such a fatal error occurs?

Nathan,
Usually, Exceptions in COM server shouldn't bubble up. Since it's an inproc server, aborting would terminate your client application. I don't know any solution that I have implemented but does any of the following help you device a framework -
1. Supporting ISupportErrorInfo for rich error information and your methods could fail with some HRESULT. Client is expected to take necessary action.
2. Not a good one, but if these are internal error and assuming there is no method call in progress, you could implement an event handler and notify client of this exception.
Just back from work so can't think of any more solutions 
Let me know if this helps.

Thanks! That's about what I thought. From what I've read, E_UNEXPECTED is intended for that sort of thing.

Yes. by HRESULT I meant E_UNEXPECTED in this case, but you may want to specialize this error code if required.

Hello all
I'm trying to use activeX to write a web interface for my application.
Does anyone know where to start to learn how to write activeX controls using C/C++ without ATL or MFC but accessing it from scratch.
Or can anyone recommend any good books?
thx

I just want to make a software that needs some calculations and waveform plot in matlab 7...
I have written the required .m files and using the combuilder of matlab 7 to generate the com files to be used in VB .Net. but after compilation in VB .Net the generated stand alone exe file still needs the MATLAB RUNTIME LIBRARY. Is there any possible way to make it independent of The MATLAB And its Run time library....
if I compile the .m file to generate .exe file using matlab... then also the dependency remains...
plz tell me how this can be solved.....
Thank You.......

You cant because the way COM operates. The matlab Client (COM VB Object) will allways referenciate to a Matlab Server. Maybe you can connect to a Matlab Server in another Machine but you will always depend on the runtime libraries because the server needs them.

Hey everyone!
I'm not sure if this is the right place, but I'm having some issues trying to debug a managed application invoking a COM server.
When I attach the native debugger, the modules window of visual studio tells me that there are no symbols loaded for my interop assembly (Interop.xxx.dll). It fails to load xxx.pdb, which I can understand. However, I have no idea how I have to generate the symbols. I've tried looking in the usage of tlbimp, but no such luck.
Any pointers on this?

Hey Sohail, thanks for the quick reply. However, I think this is not what I need, as the dll I'm using is one of my own, and not one provided by Windows. I have the debugging symbols of the original dll, but they won't work with the interop dll I've generated with tlbimp (it complains when I try to load it in the modules view). Do I have to use the original pdb or is there a way to generate one from the interop dll?

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

EDIT: I found something called HTMLDivision - can anyone tell me what it is?

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.

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?
