Re: C# and COM - exporting enum-s Vitaly Tomilov4-Jan-07 3:11 Vitaly Tomilov 4-Jan-07 3:11  My question is on C# and COM at the same time - which is the right place to post then, if not in both C# and COM forums?.... Free C++ libraries with source code on www.neatcpp.com: TWAIN, DirectShow, Interprocess Communications, etc... Re: C# and COM - exporting enum-s Pete O'Hanlon5-Jan-07 3:30 Pete O'Hanlon 5-Jan-07 3:30  It is normal to post them on one forum. Pick the one that you think is most appropriate and then post it there. In this case, it is more relevant to the C# forum because that is where you want to override the enum. the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer Deja View - the feeling that you've seen this post before. attaching com component to window (CWnd) praveen kumar agarwal3-Jan-07 20:38 praveen kumar agarwal 3-Jan-07 20:38  Sir, I have a third party component, which has displaying graphical chart functionality. This chart functionality is implemented as a part of coClass and an interface is provided to user. Using this interface i need to access the methods and properties of component. Could you throw some light on how to attach this component class to ole containers document window at runtime. I have used coCreateInstance to create the class, but i want to know how can i attach this class to CWnd(window) class at runtime. so that i can get chart displayed at runtime in document window. Thanks in advance.

For OleCreate you need to have an OleDocumentContainer in which you will host the control. Look at the help of OleCreate in MSDN and tell me if you get any problem.

(2) The SOFT side: It depends on the software env you're using. (e.g. you can use Windows API such as ReadFile or the COM control MsComm). Hope that helps.

I wrote: (1) VB6 applications using MsComm control. (2) C++ ones using the Win32 API (CreateFile(), ReadFile(), WriteFile(). the (1) are fairly simpler, 'cause the (2) are much more low level (and usually you've to deal with threads. Of course you can also use MsComm control in C++ applications (for instance using MFC). Though I've never done it. AFAIK the .NET framework provides (so Visual Basic.NET, C#, ...) a SerialPort component that can make communication stuff as easy as MsComm do for VB6 (I never made an attempt). There is also a Microsoft example [^]. hope that helps.

I tried aspose too, but it was not meeting our requirements. Because they want a tool which takes the documents as it is like DSO Framer. In aspose to change the document format we need to change the code also. And I need to email this document too. So that document may be changed so frequently. And dont forget that document must have to be made using .Net frame work library(com component is not preferable). What shoud I use in this case. Please help me. Thank you.

How to make a toolbar for mozilla georgekjolly28-Dec-06 22:26 georgekjolly 28-Dec-06 22:26  Hi all, I have already made a toolbar for IE, Now my requirement is to make a toolbar for Mozilla also .But I am not finding any sample source code or help for that.So how can I make a toolbar for mozilla. Please Help me. Thanks in Advance George Re: How to make a toolbar for mozilla User 21559728-Dec-06 23:17 User 215597 28-Dec-06 23:17  Unlike IE, Mozilla uses some XML files for adding the toolbar. All info related to developing extensions for mozilla can be found at http://developer.mozilla.org/[^] For adding toolbar, you may want to see following - http://developer.mozilla.org/en/docs/XUL_Tutorial:Toolbars[^] I hope this helps.

Re: How to make a toolbar for mozilla georgekjolly28-Dec-06 23:43 georgekjolly 28-Dec-06 23:43  Hi Sohail, Thank you for ur valid information. Actually I have made an IE toolbar using vc++ ATL COM. It cotains Threads, And many things that mfc supports. For example, It consists of a Ticker that shows some information from a server. The ticker is actually a class inherited from CStatic. And also Threads in VC++ , that performs various functionalities like, Collecting data from Server. Showing Advertisements live , from different sites etc. So I think, I cant perform these things in Mozilla tool bar made from XML. Right na. Thanks George Re: How to make a toolbar for mozilla [modified] User 21559730-Dec-06 8:09 User 215597 30-Dec-06 8:09  well you can certainly do in Mozilla what you have so far created in IE. From what you said, I beleive your UI logic and Business logic are clubbed together and created only for IE. If you seperate out the UI logic of toolbar in your IE and put the business logic in a seperate COM dll which is callable from the UI logic then you can invoke the same business logic from within Mozilla toolbar. The UI logic of toolbar is written in XML but there is a way to call COM interface methods. Mozilla also has something called XPCom - COM variant.

Sakthiu27-Dec-06 23:40 Sakthiu 27-Dec-06 23:40  you want to use that COM dll .. right ? then you have to register that COM dll in to your system. To do that pres 'Start' button take 'Run' Applicaiotn, inside Run win type 'Regsvr32' then space your COM dll file location. for example., you COM file location is C:\\app.dll then in Run window, type 'regsvr32 c:\\app.dll' press enter now your COM dll is register wit your system. then write COM client program using api's like CoInitialize(NULL),CoCreateInsatnce() and CoUninitialize(); This is the way you have to use COM dll. bye.
