Hi,
I have a really annoying problem, and I can't find the solution to it. Hopefully someone here can help me.
When I run my application on Win XP with themes activated, sometimes the vertical scrollbar in my childwindows locks and can't be used. Though I can still scroll with left/right on the keyboard.
The app works fine on 2000/XP without theme.
The app is an MDI application, and in one of the windowcontrols, I have a windowcontrol and then a childwindow control. 
It is the childwindow controls that locks, but only the ones I've created by myself. A CListCtrl for example works perfectly. It's like my controls doesn't get that the scrollbar is used.
I really, really hope someone can shed some light on this for me

You want to put your view class in a DLL? Or your Frame class? or both?

What does your video player do when a second instance is started?

hi,
when the second instance gets started,a new player will be downloaded again.As soon as the new player downloads,the older player is crashed and the new player starts playing the old cam file.
Any solution for this..
thanks in advance

This question would probably be better answered in the COM forum ... but here goes:
Is this an OCX, DLL, or EXE? Specifically, is it running in process or out of process? If it is running in process, you shouldn't have this problem ... but if you do, chances are it is due to holding onto the sound or video resources so that another instance cannot access them. If it is out of process, are you starting a new instance for each time it is instantiated, or are you trying to use the same instance?

hi Zac,
Thanks for ur reply..
I am using dll of the activex control.I give its classId in <object> in HtmlPage(IE).
So whenver i open the IE page,Activex control Dll is downloded and then player starts downloading cam file and plays it.
So if i again open IE page,a new instance is instantiated and new player opens.This player uses the same Dll and starts downloading the cam file.
The problem is,as soon as 2nd player opens,the first player is crashing.
Any solution for this..
Thanks in advance

Hi,
If I have classes like this
class A
{
virtual void fun();
void gun(int);
int i, j;
}
class B : public A
{
virtual void fun1();
virtual void fun();
void gun(int);
virtual void run(int);
int i, j;
}
main()
{
A a;
B b;
}
Now how many vtable will create here.

Where is the class B?
If you have mistyped it , it should be like
class B:public A
Then In this case two VTABLEs will be created one for each class .
A VTABLE is created for each class containing a virtual function and for each of the class that is derived from it.
Somethings seem HARD to do, until we know how to do them.

Hi Anshuman,
In this case, how many v-tables will be crated? (Means, the derived class doesn't have its own virtual fn.s.)
class A
{
virtual void fun();
void gun(int);
int i, j;
}
class B : public A
{
void gun(int);
int i, j;
}
Thanks in advance,

In this example only one vtable will be created which (ignoring RTTI) will contain a pointer to the single virtual function A::fun. The constructor (implicitly generated by the compiler) will set the vtable pointer in class A's instance data to point to this table. If B had overridden this method then there would be another vtable for class B and B's constructor would replace the vtable pointer (set in A) with a pointer to B's vtable.

Hi everyone, i need to resize an image(sizes vary) to a thumbnail so that i can add it to an image list for a list box, what is the best way to do it.... any help would be much appreciated.
the image list and the list box work fine, but i am unable to resize the image. so when it is displayed you just see the top left hand corner of the image.
Thanks in advance

You have to create a thumbnail image by your self. Here is the code snippet for that
//lets say your original image is in BitmapOrg
BITMAP BmpInfo;
BitmapOrg.GetBitmap(&BmpInfo);
CDC *pDC=GetDC();
CDC MemDC,MemDC2;
if (MemDC.CreateCompatibleDC(pDC) && MemDC2.CreateCompatibleDC(pDC))
{
CBitmap Bitmap;
CSize szThumbnail(32,32);
if (Bitmap.CreateCompatibleBitmap(pDC,szThumbnail.cx,szThumbnail.cy))
{
CBitmap* pbmpOld=MemDC.SelectObject(&Bitmap);
CBitmap* pbmpOld2=pDC->SelectObject(&BitmapActual);
MemDC.StretchBlt(0,0,szThumbnail.cx,szThumbnail.cy,0,0,BmpInfo.bmWidth,BmpInfo.bmHeight,SRCCOPY); //this function will create a thumbnail
MemDC.SelectObject(pbmpOld);
MemDC2.SelectObject(pbmpOld2);
}
MemDC.DeleteDC();
MemDC2.DeleteDC();
}
ReleaseDC(pDC);

I think if you use StretchBltfor change size not good
see (of course its a suggestion)
<br />
CRect rect;<br />
Image *img ;<br />
ImageAttributes imAttrib; <br />
<br />
Graphics graphics(GetDC()->m_hDC) ;<br />
GetWindowRect(rect);<br />
ScreenToClient(rect);<br />
img = Image::FromFile(L"D:\\0.bmp") ;<br />
graphics.DrawImage(img,Rect(0,0,rect.right/2,rect.bottom/2),<br />
0,0,img ->GetWidth(),img ->GetHeight(),<br />
UnitPixel,&imAttrib);<br />

;Pcreate a dialog, and use time event......

Make a dialog box as you want. Now create this dialog using DoModal() in a thread function. Just initiate that thread when you want to show that dialog and kill the thread when you want to make the dialog disappeared.
Good luck
