Hi all,
I need to transfer all data in RTF format from native MS Word format. The best thing that i did is to open DOC in MS Word and save it RTF format. But the problem that it's taking so long. I tried to make call Copy to selection and then paste it somewhere, it's working very fast, but the problem that it's messing up a clipboard. Can someone help me with such problem?
Maybe there is a way to transfer data directly from Word to my app. like DDE or something?
Please post your comments. It's very urgent.
Thanx.

Hi
I understand that using IDispatch a COM object exposes the functionality. But is it necesary for all the COM objects to use IDispatch?
Thanks in advance
|
|
|
|
|
IDispatch using only for automation. It is necesary for all the COM objects to use IUnknown
Best regards,
Baron

The IDispatch supports that the script and binnary can access,but Iunknown only supports binnary.
if your com object is only accessed by binnary,you use IUnknown.

You need to derive your interfaces from IDispatch if you want to access the COMponents from scripting clients like VBScript..

HI,
I'm building COM obejct in C++ and using it in C# and I can't figure out which type in C++ coresponds to bool type in C#. If I use bool in C++ , I allways get "expecting a type specification near "bool" " error. I tried boolean or BOOL , but any of them corresponds to bool in C# (after COM object is wrapped in .NET VS)
Do you have anty idea how what to use?

It is BOOL.

BOOL(C++) corresponds to int(C#)

Use VARIANT_BOOL instead.

I am working in a COM project where i need to communicate with Mainframes (CICS) for storing and retrieving data. So i want information about this problem like how to communicate or is there any interface useful for this situation?
|

I require a software component to be added to an existing .net application(web based). The coponent or the software should posses the following features:
1. It should provide PC to Phone integration either on VOIP technology or TAPI or both.
2. It should provide automated phone dialing from phone number lists.
3. Transfer calls to other users internally.
4. Record conversations and provide automated call reports and statistics.
5. Every phone number in the system should be automatically clickable and the call details must be logged to that user.
6. The phone call must be recorded and stored as a sound file.
Can anyone help me to find any freewares or commercial products available in the market which can provide me the above features.
Thanks in Advance

Hi
I am writing two interfaces in two separate DLLs. The interfaces are named IID_Draw and IID_Draw, but I associate a unqiue GUID with each of the interfaces. Now when I create an interface pointer of the IID_Draw of the 1st DLL, how COM resolves this kind of calls.
|
|
|
|
|
- IID_DRAW is a constant you define in your code. The value of this constant is a unique GUID
- Now looking at your question, I believe you have got these constants defined either by wizard or #import or something similar.
If this is the case, then you have to resolve this ambiguity by explicitly specifiying the namespace (it has nothing to do with COM runtime, it's more about how you code the wrapper classes or constants).
For example if you have done #import <dll or="" tlb=""> in your code, then check the generated .TLH file. You will find namespace here.
I hope this helps.

I have a dll that implements connection points. Now I have a client that uses the dll using CreateInstance(..)& queryinterface. Now how do I receive events from the DLL. I guess it should be like registering a callback function for the events inside the dll? Dont know.. how to go?
----------------------------
286? WOWW!

- If you are not using MFC, Check IConnectionPointContainer and IConnectionPoint interfaces
- MFC has functions -> AfxConnectionAdvise and AfxConnectionUnadvise

Hi there. Writing a WORD Addin for the first time. What I want to do is cycle through the characters in a WORD Doc. Everytime I find a particular character, I want to check what character comes after it. Depending on what I find I may want to add a new character.
My question is this:
Is there a way for me to access the actual stream of characters that make up the word doc? If not, am I right to assume the recommended approach to this is to make use of the find/replace mechanism offered by the object model?
Thanks,
Ciaran

Can anyone please help me or give me some sample code? I need to create an ATL COM service (not a DLL) which has a dummy interface.. say. add 2 numbers.. After creating the service, i want to register it as a windows service. Then i want to create a client which connects to this service and uses the interface.. (adds 2 numbers)
I have searched online and there is not a decent article which explains the process step by step... Any help in this regard will be very useful.
Thanks in advance!!!!
