If you type hr,hr in the watch window, you can see what the error is, in text.
This might help
Also try to type @EAX,hr in the watch window, then you can always see the last returned HRESULT

Thanks for your response,
The error is "No such interface supported" and I don't know why?
Thanks again,
Ken

Because you are passing the CLSID again where you should be passing the IID of the interface you want - IID_IDispatch.

Hello all,
I'm using a CListView class in report mode,in my splitter window.When I'm trying to insert items, I see that although I can add the first item data, I cannot see other items(i.e. I can see Hello and the World column, but no entry under it. Help??
//Precreate window -
//cs.style |= LVS_REPORT|LVS_SORTASCENDING; //set list styles
//then
InsertColumn(0,IDS_HELLO);
InsertColumn(1,IDS_WORLD);
CString szHello("Hello");
CString szWorld("World");
CListCtrl& list = GetListCtrl();
ZeroMemory((void*) &Item, sizeof(Item));
Item.mask = LVIF_TEXT;
Item.iItem = 0;
Item.iSubItem = 0;
Item.pszText = (LPTSTR)(LPCTSTR)szSubject;
list.InsertItem(&Item);
list.SetItemText(0,1,(LPTSTR)(LPCTSTR)szWorld);
Hush,hush...

Turn off the sort style, does it work then? If so, then the item you insert isn't ending up at index 0 because of sorting. You need to save the return value from InsertItem() which is the index that the item is actually inserted at, and use that index in the SetItemText() call.

No, Mike, that did not solve it. I took another llok at the MFC rowlist sample, and it only works when I first enter the first item for all rows via InsertItem(), and then do SetItemText() for subitems. But no matter what I do, I can never make 'real' per row basis item insertion...ie an InsertItem() followed by SetItemText() for sub items before moving on to the next row.??
I have tried both CListCtrl::xxxx as well as ListView_xxx functions, but nothing works.

I'm working with this third party SDK, which consists of a dll some headerfiles and a couple of lib files.
The SDK is written in VC6.
If I use it from a normal MFC application I have no problems.
From an ATL exe, no problems.
From an ATL dll, bang! Unresolved externals. There is something strange going on that makes the linker go kinda crazy 
Any ideas?
Maybe I should add that the SDK is written in C++, not C. It uses classes as parameters in functions 
[edit]
Here is the errors from the linker
MPDOKManager.obj : error LNK2001: unresolved external symbol "char const * const dok::szSDKVersion" (?szSDKVersion@dok@@3PBDB)
MPDOKManager.obj : error LNK2001: unresolved external symbol "public: virtual __thiscall CObserver::~CObserver(void)" (??1CObserver@@UAE@XZ)

How do you create a connection to a shared network printer and set it as default. I love C, but need to create logon "scripts" without the script. No VBS, please!

Umm, U can try to map it... WNetAddConnectionX, NetUse*

Let me guess: SetPrinter?

I've got my declaration of canal tree which has a static array of ID's of icons. I then derive another tree control class from canal tree called RPhysicalTree.

Move the definition of the array to a CPP file. The way it is currently, one m_icons array is defined for every CPP file that includes that header, which leads to the linker error

Hi:
I'm beginner in activex programming with VC++ and i have a problem!
How can i create a multi-choice property for an activex control !!!!?
for example suppose an activex have a property with following features (through ClassWizard)
External Name : BorderStyle
Type : CString (for example)
Variable Name : m_borderStyle
Notification Function : OnBorderStyleChanged
Implementation : Member Variable (Radio Button)
and this property have some value such as (note that : more than three property !!! this is very important for me)
1) None
2) Flat
3) Static_Edge
4) Three_D
5) Button_Edge
6) Client_edge
and etc.
Now i want show this values in a drop-down list in the "ALL" Activex's property sheet and user select one of them
from it.
Please help me.
My english isn't very well, please excuse me for bad comments.
Thanks a lot.

I don't think you can directly....
Manually edit idl place something like:
typedef [uuid(8216ACE0-8C0F-40AF-AA1E-5E988573C582)]
enum {
[helpstring("1 - bsNone")] bsNone = 1,
[helpstring("2 - bsFlat")] bsFlat = 2,
[helpstring("3 - bsStatic_Edge")] bsStatic_Edge = 3,
.....
}BorderStylesConstants;
....
Change interface to look like...
[id(44444), propget] HRESULT SetStyle(BorderStylesConstants borderStyle);

Here is what I want to do
VB front end is main app
DLL # 1 creates an array of doubles
DLL # 2 performs some task on an array of doubles passed to it
Vb frontend will get a pointer to an array of doubles (double * array) from DLL #1 and pass the pointer to DLL #2 which accepts pointers to arrays of doubles.
How do I get VB to do this ie. recognize what a pointer to a array of doubles is??????
Thanks in advance for all help
|
|
|
|
|
Between dll's you can pass pointer like long value and inside the second dll you can assign this long to the real pointer and do the conversion
|
|
|
|
|
Thanks for the reply.
I thought about that but my ploblem is that the 2nd DLL(receiving the pointer) must have a (double*) as it's parameter. I can not redeclare the function to accept "void pointers". If I could, I would.
Any other suggestions?

Is it possible to add a hook to keyboard from a services
I want to add the hook when the service is starting and remove the hook when the service is stop.
I tried but the hook can not be installed.
Thanks
Florian

|

Yes you can, the only thing that you must consider is that a system wide keyboard hook must be placed inside a DLL.
Then you should create a DLL that contains the hook (the callback function) and remember that the service must have a mesage pump.
If you have more questions or if I have not been so clear, (or if I've completely missed the shot) don't mind to ask again.
Hope this helps...

Hi Everyone,
I have an application that is designed to load an image from the database. This image is in a compressed form like png, jpeg etc. I was wondering what is the process to loading the bitmap if it is already in memory (ie. not loading it from the disk)? Should I use something like FileMaps or something else?
Cheers,
Clint

|

there are a half-dozen articles on CP that handle image I/O. most of them can handle memory-based images. look in the "Bitmap and Palettes" section.

Hi Chris,
I did go through them, unfortunately they deal with their own classes. I would like to be able to use CImage (which supports decompressing png) from the MFC library. So what I need to know is how do I tell windows that this compressed png file is in memory and not on disk without having to save a temp file to disk?
Cheers,
Clint

|

i'm not familiar with CImage, but the MSDN says its Load method can take an IStream interface. so, you could hook up some kind of IStream-based COM object to read your memory-based image. (yeah, yuck)
