In your command window, have you run VCVARS32.BAT ?
This will set stuff like LIB and INCLUDE for you, although it may not be 100% correct, it will have all the VC++ directories.

Hi All,
I have a windows service installed on Machine having XP2 Service pack 2 OS.
I am using this call in Run() Method,
hr = CoInitializeSecurity(NULL, -1, NULL, NULL,
RPC_C_AUTHN_LEVEL_NONE, RPC_C_IMP_LEVEL_IMPERSONATE, NULL,
EOAC_NONE, NULL);
If i access this service from other computer it gives access denied error.
If i disable Firewall security from Control Panel->Windows Firewall,and in Dcomcnfg add ANONYMOUS user and give it full access,
access denied problem goes.
Why do i want to add ANONYMOUS in Dcomconfg even i disable Firewall security??
if i dont want to do all above settings but still my service should be accessed from other computer ,what should i do,is there any way for this??
Any help is appreciated.
Thanks

Hi,
I have developed an application, which supports File save / read logic using Structure Storage (mentioned on this site). I am storing very complicated structure in the file. Now I want to support typical file versioning system. So that even if I changed (add new elements in present structure), till it should be able to support backward file reading capabilities.
Does anyone has come accross such senario? How the design was done in this senario? My present design is - It will call say GetDataFor130() or GetDataFor100() (where 130 means ver 1.30, 100 means ver 1.00.) GetDataFor130() will internally call GetDataFor100() and then read or write the additional elements. So backward compatibility is maintained with minimum code complexity.
Thanks & Regards,
Anonymous

Visual C++ 6.0's ATL wizard creates two different release configurations: ReleaseMinSize and ReleaseMinDependency. The minimum dependency version links to the C run-time statically and includes the ATL registration code. The minimum size version links to the DLL version of the C run-time and links to atl.dll for registration.
In the second case, you would have to distribute msvcrt.dll (installed by default on Windows 2000 and later, so you can skip it if you're targetting one of these systems) and atl.dll.
You can select different combinations by defining (or not defining) the symbols _ATL_MIN_CRT, _ATL_STATIC_REGISTRY, and changing the C run-time library version you're using. If you're not using the C run-time at all, you can define _ATL_MIN_CRT.

Hi all,
I have created a simple FULL control, also i have registered a new MIME type for it.
Now, When i create a new file say test.myext and open it with IE. it show the Control taking full page on IE Window and spying these window -
It looks something like this
---C:\temp.bisfext
|---Other Windows
|---Other Windows
|--- Shell DocObject View
|-Internet Explorer_Server
But I have seen some few application where in if you embed you control in IE Window then IE Show something Like
---C:\temp.bisfext
|---Other Windows
|---Other Windows
|--- Shell DocObject View
|-Internet Explorer_Server
|-ATL:XXXXXXXX
Can anyone please explain me what is the difference between the two?
Thanks in Advance

Please Help me.
I hope someone help me for that
Thanking You,

I am a COM newbie, and I would like to use the MAPI address book in one of my apps.
According to the documentation I got, the function I want is IAddrBook::Address.
Now IAddrBook is declared as IAddrBook : IMapiProp which tells me it is derived from IMapiProp.
My question is how do I get an instance of IAddrBook into my MFC app so that i can use it?
The interface ID is IDD_IAddrBook and the pointer type is LPADRBOOK which are declared in in the file "MAPIX.h" which is all fine, but to use CoCreateInstance() to create an instance of IAddrBook I need a class ID. What is, or where do I find, the CLSID for IAddrBook. Or is there an other way to load an instance of IAddrBook?
Please do not point me to WABOPen as that function will return Internet Explorer's cutdown subset of MAPI's IAddrBook interface. I want to gain access to MAPI's full featured IAddrBook.
Also, if anyone can recommend some good books on COM basics for beginners, I would be greatful 
Thanks.

__uuidof(IAddrBook)
will this work for you?
Have you considered using smartpointers, since you are a newbie as you said, it would be helpful for you.

Thanks for the pointer, but unfortunately it does not work
LPADRBOOK pa = NULL;
HRESULT hr = CoCreateInstance(__uuidof(IAddrBook), NULL, CLSCTX_INPROC_SERVER, IID_IAddrBook, &pa); gives me
error C2787: 'IAddrBook' : no GUID has been associated with this object Surely there must be a way to load an IAddrBook object
It can't be that difficult, all I need is point in the right direction

I am not that expert in com either, but i guess this should work.
HRESULT hr = CoCreateInstance(IDD_IAddrBook, NULL, CLSCTX_INPROC_SERVER, IID_IAddrBook, &pa);
before that , did you import the tlb file ?

hi
clsid for IAddrBook is {4D2F086C-6EA3-101B-A18A-00AA00446E07}. I just took it from the registry. but it seems mapi.dll is supposed to use by calling the exported mapi functions in that dll. Even if the dll is com compliant, it is not iDispatch impliemnted and also it exports a large number of functions for varuois kind of operations with outlook. So it better to go for that built in functions than the com functions. So to get the IAddrBook pointer u can use pSession -> OpenAddressBook. This will return LPADRBOOK. To get a valid pSession variable, call MAPIInitialize and MAPILogonEx .

Question:
How to return SafeArray inside of Variant from COM component?
My COM component is out-of-process component ie.EXE and client
is coded in VB. I am building communications interface for
VB clients and have a need to return array of bytes.
Passing of Variant arry to COM-component thru IDispatch is ok and
returning of parameters that are not arrays is also working.
Any help is warmly welcomed!
Example code from idl which tries to return array thru inVal - parameter:
[id(7), helpstring("method to Test3 interface with Variants")] HRESULT get_Test3( [in, out] VARIANT *inVal, [out, retval]VARIANT *pVal);
Declaration on C++ :
STDMETHOD(get_Test3(/*[in, out]*/ VARIANT *inVal, /*[out, retval]*/ VARIANT *pVal);)
And Implementation:
STDMETHODIMP TestClass::get_Test3(/*[in, out]*/ VARIANT *inVal, /*[out, retval]*/ VARIANT *outVal){
ZeroMemory(inVal, sizeof(VARIANT));
BYTE dummyInput[3] = {0,1,2};
CDispatchHelper::ConvertFromBytePtr2Variant(dummyInput,&inVal);
return S_OK;
}
And implementation of ConvertFromBytePtr2Variant() - fucntion
//Converts given byte array to SAFEARRAY contained in Variant.
//NOTE: Now this just creates array of 100 ints for testing purposes
BOOL CDispatchHelper::ConvertFromBytePtr2Variant(BYTE *_byteToConvert, VARIANT **_ppResult)
{
SAFEARRAY *pNewSafeArray = NULL;
// one dimensional array with 100 elements and
// zero-based indexing
SAFEARRAYBOUND rgb [] = { 100, 0 };
// allocate the memory for the descriptor
// and the array data
pNewSafeArray = SafeArrayCreate(VT_I4, 1, rgb);
if (pNewSafeArray) {
// get ptr to array base
long *rgelems;
SafeArrayAccessData(pNewSafeArray, (void**)&rgelems);
// initialize each element
for (int c = 0; c < 100; c++)
rgelems[c] = c;
// release lock on array state
SafeArrayUnaccessData(pNewSafeArray);
}
//Now we have safe array in pNewSafeArray
//Put array in Variant
*_ppResult = new VARIANT;
if (*_ppResult == NULL){
ATLASSERT(FALSE);
return FALSE;
}
ZeroMemory(*_ppResult, sizeof(VARIANT));
(**_ppResult).vt = VT_I4 | VT_ARRAY;
(**_ppResult).parray = pNewSafeArray;
return TRUE;
}
VBClient side code is this:
Dim testInOut As Variant
testOut = oIdiootti.get_Test2(testInOut)
'Here value of testInOut is not changed, if transaction were succesfull
'parameter should contain 100 integers with values 0,1,2,3...
|
|
|
|
|
Now I tried to create array of bytes before sending array to COM - component and in component I write just to these allocated bytes. Result is succesfull transaction. But if I try to create new array using SafeArrayCreate() APIs transfer wont succeed.
Any sound explanations would be helpfull.

Hi,
I am trying to open a word template that has auto macros that fire when the template is opened. I need to disable these programmatically.
In Delphi you can use the following to achieve this:-
OleVaraint(myWordApp.WordBasic).DisableAutoMacros;
myWordApp.Documents.Open(blaa...blaaa...blaa...
I really need a way to do this in .net (C# if possible).
Any help would be most appreciated.
P.S. Anybody know any other good places to ask?

hey, i was wondering if can anyone tell me a way to override the default actions of a certain control, create new ones, and disables ones.
let's say i have a control X, we all know that in API, all r considered as windows. Let's say i have its handle. and this X control is inside my window Y. I want to know if there's a way to add new "message handles" for this control: what if this control doesnt support left click and i want to add one? (i could use the left click on the parent using some coordinates calculations) , how about overriding existing events? Ie: I want the button to be clicked when i press the right click. (i'll suppose that the control doesnt have any event capture for the right click). and... what if i want to disable the left click on this control?... I know all those stuff have a certain way to be dealt with. In order to override some functions, i used followed the mouse on the parent, when it's inside the window, and its location has changed, i'll SetCapture on the parent. any better ideas about this subject? ... my way works but not perfectly (i will have to send all the other msgs i need to the control which will make the job lengthy),that's why I need ur help guys
