I noticed that in VS 2005, the return values of GetCount method of CList and CArray and their derived classes are of INT_PTR. I am wondering why INT_PTR not int or long? To me, that is getting messy of MFC 7.0 or higher in dealing with data types.
Thanks.

In basetsd.h, it is defined as an int (or __int64).

Hi, you can you const int nLength = (int)pArray.GetSize() to remove all the 4 level warnings in your application - i'm dealing with 32 bit applications.

I am using directshow to develop some applications. I need to use IMediaSeeking::setpositions to set start position and stop position to run the buildergraph to write a segment of a song. As I use setpositions function, hr = E_NOTIMPL. Thanks for any information about this problem.

Why would you think it useful to navigate through 256 different windows?

I remember seeing an article somewhere, maybe here on CP, where a splitter was used to create a table. Each 'window' displayed a simple float. I know its not really related, just thought I would mention it.
I couldn't help thinking of the overhead and code which goes into managing so many windows.

I would think a grid control would be better suited for the job.

Hello.
Dunno that MFC or COM question.
How to construct or attach to ActiveX Control wrapper class, derived from CWnd, already exist COM object exposed LPDISPATCH.

You can try CWnd::GetControlUnknown() from the control container or CCmdTarget::GetControllingUnknown() inside an ActiveX control's source(an undocumented function and may not function in future versions of MFC)

I posted this same question two days ago but have so far not gotten an answer. I am assuming that there is no way to do what I want, but I will ask again just in case someone who does know missed my question the first time.
Given an HCURSOR handle, how can one tell if it is an animated cursor (loaded from an .ani file or RT_ANICURSOR resource) or not?

A cursor is almost identical to an Icon. So in theory you should be able to use the ExtractIconEx() function to return an array of Icons. If you have more than one icon, then you are dealing with an animated cursor.
Take a look here[^] for more ideas.

The theory is not bad, but unfortunately it does not work. ExtractIcon and ExtractIconEx are used to retrieve icons from a file (.exe, .dll, or .ico), not from an HICON or HCURSOR handle.
I am writing a wrapper class around HCURSOR, and there are some things that I can do with a static cursor that I can not do with an animated one, such as compare them to see if they are the same or change the location of the hotspot. Being able to tell if an HCURSOR is animated or not would be handy.

Then why don't you try the DrawIconEx and set the istepIfAniCur member to something greater than 0. I'm sure the function would fail if it's not an animated cursor.
|
|
|
|
|
From MSDN:
istepIfAniCur
[in] Specifies the index of the frame to draw, if hIcon identifies an animated cursor.
This parameter is ignored if hIcon does not identify an animated cursor.
But I will try it anyway

I might be able to make this work, if I draw frame zero and frame one and then compare them. If they are different I got an animated cursor, if they are the same I got a static cursor. Seems like a really bad hack but until something better comes along
You may be right

Do not use the CopyCursor function for animated cursors. Instead, use the CopyImage function.
I'm wondering if CopyCursor returns an error if you pass it an animated cursor?

No error, it just creates a static cursor containing the first frame of the animated cursor.

 Hi, I am using ADO 2.81 with C++ 6.
In my program I have a datagrid which is filled with data from adodatacontrol. Whenever i select a different row, my app needs to display information about it. The problem is, I can't find in which row the user clicked...
Is there any code that can help me?
i am trying to put it in the function:
void CMyDlg::RowColChangeDatagrid(VARIANT* LastRow, short LastCol)
here lastRow shows the last row clicked not the present.
I tried with dataGrid.get_Row();
this works fine if I dont scrool the data grid. But if I do so, it gives me the same informations (like I am not scrolling)
PLS help

Hello all,
Will u give me way to claculate the execution time of a program(or between any statemants) in Microseconds (in VC++).
I was able to get the execution time in Milliseconds anyway by using GetTickCount API.
Are there any way to calaculate in Microseconds(programmatically!!!!!!).
Problem in above said API is that,when the range goes below 0 (in ms), the Microsecond
value is not displayed( but rather 0 is Displayed).
I am in immediate need!!
Thanks in advace..

Yes, just multiply milliseconds by 1000.

But I was not able to get values below 0 ms.(in microseconds range).If it is more ur ans is correct.
For Ex:
Try finding the execution time of 2 or 3 statements, u will get the answer as 0 ms.
Isn't it.
Then what is the time spent in executing those statements!!!.
Thanks 4 ur Reply

With a little work, you can get there. You'll need to use the function QueryPerformanceCounter()[^] along with QueryPerformanceFrequency()[^].
Before you start though, you should really read an excellent article here on CP by Joseph Newcomer: Time is the Simplest Thing... to make sure you have a grasp of the many things that can ( and will! ) throw off your timing measurements in the Windows environment.
