Sometimes, a proxy/stub Dll needs to be registered. Does your application make use of an external proxy/stub dll?

It does, and the same problem occurs. I believe the PS dll loads stuff under the AppID key under HKCR? Either way, when I regsvr32 either one of them, they both "succeed" but neither actually touches the registry.

Oops. The PS does NOT put entries in AppID. My mistake.
The problem remains.

Try to move the ATL.DLL with you.

Hello...I already posted this in the "Visual C++" area, but I've gotten no response, so I'm trying it here, since it's technically a COM issue. 
I'm working on a namespace extension for Windows NT that represents documents in a repository. It allows the user to copy or cut the documents and paste them to the file system. I'm basically doing the cut/copy by retrieving the files, copying them to /temp, and creating an IDataObject instance on the clipboard which returns a reference to the temporary files in CF_HDROP format.
BUT...in the case of a cut and paste, I need to get feedback that the paste was successful so I know whether or not to delete the document object from the repository. I get a "Paste Successful" via IDataObject::SetData(), but if the file already exists where I'm pasting it, I get a "File already exists - overwrite?" dialog box *AFTER* the "Paste Successful" has already been returned!
Is there a way to verify that the paste has actually occured?
Alternatively, is there a way I can add a handler of some sort to the shell that will allow me to paste documents to the file system that are in a custom clipboard format?
Any help would be greatly appreciated.
Thanks,
Tim

Hello,
I want to write a program that show some Powerpoint slides through LAN.
Could Office Developer help me anything?
please help me!
Thanks,

I am not a Office developer, but you have several options, for example, Powerpoint have a little quik view for it, in that case you only need to destribuit that application. If you are a Vsual c++ developer you can use Ole Automation....

Hi all,
I want to display my own HTML pages instead of IE res: error pages(dnserror.html etc). I know that the AboutURLs reg entries handle some of these but not the DNSerror. Now in my mind there are 2 ways to do this: either write a BHO IEplugin and trap IE events esp. BeforeNavigate2 and if res:// protocol pages comeup I just call Navigate() to go to my pages. the other idea is to replace shdocvw.dll and shdoclc.dll resources(I'm not sure of the merits/demerits of this). But then XXXUpdateResource() API's work only for WinNT and I want Win9x compatibility too. What should I do?
TIA.

I want to be able to generate a CLSID, but I always want the first 4 sections (best case) to be the same like so:
51eb18c0-98a7-11d1-83d1-f46705c10000
51eb18c0-98a7-11d1-83d1-f46705c10001
51eb18c0-98a7-11d1-83d1-f46705c10002
51eb18c0-98a7-11d1-83d1-f46705c10003
I need this to happen regardless of the machine's on a network or not. The first four sections should be different for each machine the program is run on as well.
Is this possible?

John you are a moron. That would defeat the purpose of a GUID. You want it to be a "GLOBLE UNIQUE IDENTIFYER" if MS allowed what you want then there would be a bunch of COM components with the same GUID.

Anonymous? Despite your obvious "know-it-all" status (I should have seen the great big DICK in the middle of your forehead before asking the question), you haven't got a freakin clue as to why I'm even ASKING this kind of question.
Do you even know the answer? Hmmm, I thought not.
Besides all of that, if you're too chickenshit to use your real name, I don't have any more time to spend on your worthless fecal-brained ass.

So, you delete your posts so that any late-comers won't know you're an a**hole. Funny thing is, you can't delete a post that was done anonymously. Well, for every's informationm, the drivel that this post is in response to was posted by one Roger Smith.

You could try creating them yourself
<br />
GUID BaseGuid;<br />
CoCreateGuid(&BaseGuid);<br />
<br />
GUID MySecondGuid;<br />
MySecondGuid.Data1 = BaseGuid.Data1;<br />
MySecondGuid.Data2 = BaseGuid.Data2;<br />
MySecondGuid.Data3 = BaseGuid.Data3;<br />
<br />
MySecondGuid.Data4 = Whatever you want<br />

I need the whole thing to be generated programatically (by the windows api). I think I found the answer, but I need a new version of the platform SDK to get the function prototype.

What function are you using, or thinking of using? It might come in handy for something I've been considering.

In Win2K, use UuidCreateSequential to get sequential guids.
In Win9x, using UuidCreate will do the same thing (I think).

You need to have at least the February 20001 release of the SDK to get the correct code. My SDK at home is too early of a version.

Hi John,
You can create consecutive GUID's with the UuidGen utility. Use the -nXXX command line switch. According to the MSDN documentation, you can create sequential guid's programmatically by creating a single GUID (with CoCreateGuid), and then incrementing the FIRST word of each subsequent GUID. So, I don't think you want to increment the last word of the GUID as shown, since this may result in non-unique GUID's; it appears that the first word of the set is the one that is generated from the time on the machine, not the last one. This should satisfy that the GUID's are unique across machines as well, since you aren't messing with the part that contains the MAC address of the machine.
// MSDN Documentation, search for "GUID Creation and Optimizations"
For example, if you were to type
uuidgen -n5 -s >guids.txt
the uuidgen utility would generate a block of UUIDs similar to the following:
{12340001-4980-1920-6788-123456789012}
{12340002-4980-1920-6788-123456789012}
{12340003-4980-1920-6788-123456789012}
{12340004-4980-1920-6788-123456789012}
{12340005-4980-1920-6788-123456789012}
One method for generating and tracking GUIDs for an entire project begins with generating a block of some arbitrarily large number of UUIDs—say, 500. For example, if you were to type
uuidgen -n500 -s >guids.txt
the utility would generate 500 consecutive UUIDs and write them to the specified text file. You could then check this file into your source tree, providing a single repository for all GUIDs to be used in a project. As people require GUIDs for their portions of the project, they can check out the file, take however many GUIDs they need, marking them as taken and leaving a note about where in the code or "spec" they are using them.

Those wouldn't be UUIDs (a.k.a. CLSID, GUID, IID).

I am working on a project that will recieve netmeeting calls. Upon connection it will open an audiostream, and then watch the state of the INmChannelAudio object. More precisely, the INmChannelAudio object is supposed to provide an automatic callback to the INmChannelAudioNotify class, which I have written according to the samples provided by microsoft. However, for some reason it never calls back that function. Also, when I manually try to check the state of the INmChannelAudio object via the calls GetState and IsIncoming, GetState returns NM_AUDIO_TRANSFERRING once the audio object has become active, unless it has been set to pause, in which case it returns NM_AUDIO_PAUSED. IsIncoming() always returns S_FALSE, even when there is audible data coming from the speakers.
So I am led o a couple of assumptions -- Either my code to check the state is wrong, or I am connected to the object wrong. I'm almost certain my code to check the state is correct, since it changes. I am not sure about IsIncoming though, because it always returns S_FALSE. the code I have been using is
HRESULT hr;
NM_AUDIO_STATE puState;
PUSER pUser = (PUSER) PUserLocal();
INmChannelAudio * pChannel = pUser->m_pChannelAudio;
pChannel->GetState(&puState);
hr = pChannel->IsIncoming();
However, no matter what, this code doesn't really matter. I am using it to debug. My main problem is the class CAudNotify which is the INmChannelAudioNotify class. As I said before, the INmChannelAudio class, which is predefined, is supposed to call back to my CAudNotify class once they are connected. Since it does not, I assume my connect code is flawed. Here is that code:
//Class declaration
class CAudNotify : public RefCount, public CNotify, public INmChannelAudioNotify
{
public:
CAudNotify();
~CAudNotify();
// INmChannelAudioNotify
HRESULT STDMETHODCALLTYPE NmUI(CONFN uNotify);

//and class code

if (pAudioChannel->IsIncoming()==S_OK){
PTTOn('A');
}
else{
PTTOn(0);
}
}
// }
return S_OK;
}
There are other bits and pieces of code in the class, but they probably have no connection.
So the problem is I don't even get that messagebox in ::MemberChanged, ::StateChanged, or ::PropertyChanged.
Please help!!
Thanks a million,
Aniel Sud
--UPDATE--
I found that the QueryInterface method is being called with several IIDs that I had not before heard of -- namely IID_IMarshall, IID_IStdMarshall, IID_IexternalConnection, and 0000001B-0000-0000-C000-000000000046. I did a search for IID_IMarshall, and came back with one newsletter that was very vague. But it did say something about requiring marshalling. What is marshalling? do I need it in this instance?
Thanks again for all the help!!
--UPDATE--
I have found out about marshalling, and I don't think I should need it in an app such as this. Moreover, I don't see anything about marshalling in the samples. Is it ok to just let these requests slide?
Thanks again!

Hi, I have a custom control who have child windows (CWnd) I Know it is possible because we can insert a CButton in a control, CButton is him-self a drived-class from CWnd,
For CButton we have to override the OnDraw function, because this fucntion will be called (instead of the OnPaint commonly used) but this function does'nt exist in a CWnd and DrawItem dosn't seem to work...
ActiveX are hard to do, lot of things to thing and to know, the exception is a rules and what you used to do don't work anymore.
thanks for you'r help

Hi,
I want to create a setup for my DCOM-Client Application.
The setup will be created using InstallShield-6.
Now, I dont want the end user to go through DCOMCNFG after
running my SetUp program.
I want my Setup Application to do all that as part of the
SetUp process.
Is it possible using InstallShield ??
Also, My client is a VB Application (I cannot use COM library
functions from within my client)
I am sorry if this post is Off-Topic in a DCOM Forum.
But please somebody direct me to a proper solution..
Thanks
Firoz
