Use the [helpstring] keyword.
[uuid(.......), version(1.0),
helpstring("iZ imaging Toolkit 2004 R1.0")
]
library MyComponentLibrary
...

Thanks Victor,
But it does not work.
When i register my component, its display name is still "MyComponentLibrary".
pls put ur comment ..
rgds,
Rana

So what is your "display name"?
Dim obj As MyComponentLibrary.SomeObjectFromLib ?
Or the title in some Dialogs "[ ] MyComponentLibrary" ?
As far COM, the "library MyComponentLibrary" gives the name of library. It cannot be changed, but only by new name.
With best wishes,
Vita

Like in Visual basic,
Open the menu Project->References.
In References dialog box the Display names of components are different than their library names.
I just want to know how can i change that name in the References dialog box.

With [helpstring] of the library statement of IDL(ODL). When I make such change, I will see it in VB project.
Hm... I see that the VB saves the name in own project. It needs for the showing of missing references. Though the VB rechanges these names before saving or opening the project.
With best wishes,
Vita

Hi,
What Victor mentioned is correct. Modifying the helpstring in IDL/ODL, will reflect in the tlb listing dlg. If you are not getting it, might be somthiing else is wrong.

Does anyone have a small C++ example on how to use the Image Mastering API (IMAPI) in Windows XP?
In what file does the type library appear in? There is an executable called imapi.exe in the System32 directory but it does not contain the type library.

Martin

Hi,
When I use the following code to create an instance of Internet Explorer, the top window seems to lose focus.
HWND hForegroundWindow = GetForegroundWindow();
CLSIDFromProgID(OLESTR("InternetExplorer.Application"), &clsid);
CoCreateInstance(clsid, NULL, CLSCTX_SERVER, IID_IUnknown, (LPVOID*)&pUnk);
pUnk->QueryInterface(IID_IWebBrowser2, (LPVOID*)&pWB);
pUnk->Release();
SetForegroundWindow(hForegroundWindow);
When CoCreateInstance function is called, the top window loses it focus, and invisible IE seems to receive the focus.
I get the handle to the foreground window and set it back after CoCreateInstance is called. However, i still do lose focus in that couple seconds. This is particularly annonying when i am tying something. Because when the top window loses its focus, the input will stop. Is there anyway to make it so that when CoCreateInstance is called, the foreground will still keep the focus?
Thanks

Hey everyone...
I have been trying to find some documentation on how to access contact (name, e-mail, phone, anniversary, etc.) info within Outlook Express. I am currently able to get at data using a typelib for Outlook 2000 and XP, but alas, it doesn't work with Outlook Express.
Does anyone know if there is a typelib avaialble, or if there is some documentation somewhere that would help me get started?
Thanks...

Hello Brigg,
Well, you are certainly asking in the right forum. I'm assuming you know COM programming. you would need it to use my sdk.
What you are looking to do with Outlook Express is possible through 'undocumented' means. Please checkout my messageboard here. I'm working on a future CP article on this, but as of now, it's not meant for public distrib.
Cheers,
Hush,hush...

Amit,
Actually, I'm not that familiar with COM. I've been using a TypeLib with Outlook 2000 and XP, so it's pretty much just accessing member functions and variables within the MSO class.
Could you possibly point me to the "undocumented" means of accessing this data? I would like to take a look at how this is done.
Thanks...

I have observed a handle leak in a COM object which acts as both a COM client and a server. This object is responsible for starting and stopping other COM objects.
In an attempt to find the handle leak, I've written an extremely simple COM object (exe) that implements a very simple interface. I also have client code that creates the COM object, calls a method on the interface and releases the interface pointer. These steps are repeated a number of times. After releasing the object, the client pauses long enough to ensure that the server dies and goes away.
Using Task Manager, I watch the client's handle count increment by one each pass through the loop.
I'm looking for clues - anyone know where the handle leak occurs?
By the way, I also tried a client using smart pointers and observed identical results in terms of leaking handles.
Here's the client code:
ILeak *pLeak;
CLSID clsid;
CoInitialize(NULL);
CLSIDFromProgID(L"Atlsvr.Leak", &clsid);
for (int i=0; i<10; i++) {
CoCreateInstance(clsid, NULL, CLSCTX_LOCAL_SERVER, IID_ILeak, (void**)&pLeak);
pLeak->Add();
pLeak->Release();
Sleep(5000);
}
CoUninitialize();

What does pLeak->Add() do? Is it adding a reference count to the object? If so, then your object never gets released....
I am by no means a COM expert, but I would assume that the CoCreateInstance init's the object with at least 1 reference on it. And at that point, the Release just brings the reference count back down to where it was created.....
Just a thought -- no expert here. It's been years since I did any COM, last one was doing OLE2 client/server stuff in the late 90s.

In this case the poorly named Add method simply returns S_OK, so the reference count isn't affected.
By the way, I did discover that by moving the CoInitialize() and CoUninitialize() inside the loop, the handle leak goes away. At this point, I'm not sure that's feasible in the code I'm working on, so I'm still interested in finding another solution to eliminating the handle leak.

Hi,
Please suggest regarding following trouble:
Create a COM component "InProcVB.dll" as in-proc DLL in VB exposing some interfaces and methods .
Write its client as "clientVB".
Write another COM component as "OutOfProc.exe" as out-of-proc exe server in VC. This has same
interface/class/InterfaceIDs/ClassIDs as that of "InProcVB.dll". This is written with purpose of
replacing "InProcVB.dll". And, the expectation is that client need not re-compile. (As defined by
rule "Location transparency of COM).
After developing "OutOfProc.exe", we unregistered "InProcVB.dll", and registered "OutOfProc.exe".
Executed "clientVB" without any change. It gave error type-mismatch. The error point was:
Dim objSrvClass as SrvClass
set SrvClass = CreateObject("Server.Class") --> Problem: Type mismatch.
If I change code as
Dim objSrvClass as Object
set SrvClass = CreateObject("Server.Class")
It works well.
Please suggest.

Anyone know where theres some good info on the audio side of DirectX?
I've read and understood most of the stuff that comes with the SDK, but are there any tutorials on using DirectX in say an audio sequencer?

I've created a COM component and now I want to install it. I've wrapped it up in an installable package using InstallShield. I can then choose to uninstall it using the Add/Remove software utility. If I want to uninstall it from another I write some code to unregister it like this:
HINSTANCE hModule = LoadLibraryA(szModuleFilename);
HRESULT (STDAPICALLTYPE *pfn)(void);
(FARPROC&)pfn = GetProcAddress(hModule, "DllUnregisterServer");
I can then delete the DLL and it's containing folder but that's not really satisfactory is it?
What's the best way of doing it? I guess there must be a way of emulating the call to the Add/Remove utility and I guess this is probably the best method. Anyone know how or have an opinion?

One solution is to run regsvr32.

That's just the same as calling the code that unregisters the DLL - it doesn't uninstall the package. Say I had installed my COM server using InstallShield which had also created some registry entries, simply calling regsvr32 or the code above would result in the COM component being no longer registered but the registry entries would still exist and anything else that had been installed as part of the package like the containing folder etc.

Hi ,
I am searching for a good sample code or article that takes a tab delimited file as input and imports it prograamatically in an access database.I don't want to loop through all the records in the text file and then put them individually into access.I want to import the whole file programmatically into an MS ACCESS table.May be it requires OLE.
Any help will be appriciated.
Thanks and regards.
