All CWaitCursor does is call SetCursor() once. If your code ends up pumping messages and receives a WM_SETCURSOR which it does not handle, DefWindowProc() will set the cursor back to the cursor specified in the window class. It sounds like this is what's happening in your app. You'll need to handle WM_SETCURSOR and keep a flag saying whether you want the hourglass cursor, and set the cursor appropriately in your WM_SETCURSOR handler.

Have you tried BeginWaitCursor and EndWaitCursor.

Yup, I have tried BeginWaitCursor(), EndWaitCursor(), I put in a message handler for WM_SETCURSOR, but again, the wait cursor shows up when I call my function from one class, but not when I call it from another, and they are both going to the same place. And yes if I put a breakpoint before my lengthy operation and then it shows up.
Thanks

You need to use the COM interface to the Document Object Model and susbscribe to events. The event notification data will contain the x,y coordinates

thanx for your reply,
I have been looking at that article before. But i thought that this way will only allow me to identify which html element the user clicked, it does not specify the exact (x,y) of user clicks.
m I wrong ???

When you receive an event you can use the IHTMLEventObj family of interfaces to get all kinds of information on the event.

By responding to the WM_LBUTTONDOWN and/or WM_MOUSEMOVE message(s).

It helps to mention this sort of thing up front. See here.

Hello,
I am writing Win32 DLL that exports functions to Excel. I use the Floating Point
Array Structure in C to pass Excel ranges :
typedef struct _FP
{
unsigned short int rows;
unsigned short int columns;
double array[1];
} FP;
I want to call the exported function from the dll directly in the Excel cells as an array formula via a declaration of the function in a VBA module as opposed to using an .XLL:
extern __declspec(dllexport) void __stdcall SimpleExample(FP *arr){
for(int j=1;j<=5;j++){
arr->array[j]=arr->array[j]*2;
}
}
(the range of cells is 5 long)
Public Declare Function DLLFunction Lib "Mydll.dll" Alias
"?SimpleExample@@YGXPAU_FP@@@Z"(ByRef outarr As double) As Double
However Excel needs to know that the argument passed in is to be "modified in
place" and returned to the calling cells using the Return Type, in this case "1K" - the first and only argument is a FP struct and is to be used as the return parameter.
If the function is registered in VBA -where does this return type code information code go? - in the ".def"
file?
Many thanks in advance for any assistance.

I think you really need to be using Automation data types to pass data in/out of Excel to VBA. You could pass in a SAFEARRAY* to contain the contents of your range. I would suggest reading up on auotmation data types.
I hope this helps.

Thanks,.. the SAFEARRAY can be used when passing variant arrays from VBA to C++. The Floating Point Array Struct is used when passing parameters that refer to Excel cell ranges directly from function calls in the cells, to and from the C/C++ dll.
A return type is needed to tell Excel of the parameter data types and return type though...

Hi all,
I want to enumerate all users in my active directory.
I found a class, but the file sddl.h is missing and there was no answer to questions regarding this file. I search the internet and all I found was, that I should use the Microsoft platform SDK. Well, I don't have it.
So, how can I get all the usernames in my active directory?

Thanks for the hint.
That was a question, I had then. The suggested solution did work as long, as my program was run on a domain controller. Now, I need a program, that can run on any client with any userrights in my domain.

Strange, as I use that function all the time on non-DC machines. What problem(s) are you seeing?

Hi all,
I want to read the attributes of a file. Sounds easy, but there must be more attributes that just "Hidden and "System" and so on.
If you open the properties of a file, then there is a property-page, where you can store the author of this document, a short description, keywords and so on. I want to read and write these informations. Can anyone tell me, how it is done?
