(Q) Integrating Macromedia Flash in C++ Application

26-Aug-02 0:31

Hi,

I need to integrate an interactive movie into a
Windows Application. I think that it is possible
to integrate Macromedia Flash 4 as an ActiveX
control into a host windows application.

Could you point me to an information source how
this can be done?

Thank you in advance.

Z.

Use the webbrowser control and load some HTML in it that loads the flash.

Minimize attribute for CPropertySheet.

Is it possible to give a minimize attribute for a PropertySheet? If so, could you show example?

Thanks!

Just pass a WS_MINIMIZE style to the Create Function.

Have a look here[^] [MSDN]. Should answer your question

I'm not using the Create function. I'm doing the following:

class CControlProp : public CPropertySheet
{
CControlProp(LPCTSTR pszCaption, CWnd* pParentWnd = NULL, UINT iSelectPage = 0);
etc.
}

and in my CControlProp::InitInstance, I do:

CControlProp cp(_T("Common Controls"));
cp.DoModal();
return FALSE;

======================

The caption and the close box for the PropertySheet appears, but I would like to get the minimize box to show also.

Thanks again for any clue.

Smile | :)

You'll have to handle WM_CREATE and use ModifyStyle to add WS_MINIMIZEBOX style.

Checking if VisualStudio is installed

I'm writing a Software which generates C-Code. This kind of Generator works calls during runtime msdev from command line to test the generated source-code. This works perfectly if VisualStudio is installed on a system but actually if this peace of generator is installed onto an other system I have to check if visual studio is installed. Does anybody know how to check if Visual Studio itself is installed on a system (checking with vc++ code) and how to get the binary-directory of vc?

thanks a lot in advance.

Thumbsize calculation MATH problems

alex.barylski25-Aug-02 22:46

I have for about 8 hours tried to figure out what the hell is wrong with my code or math and I have reached the point where the computer is going to end up outside for the night so i've given up on it and moved on to something else.

Anyways...this this snippet of code is pretty basic math so I hope someone can tell me where i'm going wrong... Cry | :((

before I go nutts...

UINT CTimelineCtrl::CalcThumbSize(UINT nVirtualWidth, UINT nVisibleWidth)
{
	// Thumb size not needed, scroll bar should be invisible
	if(nVirtualWidth <= nVisibleWidth) return -1;
	
	float temp = ((float)nVisibleWidth / (float)nVirtualWidth) * (float)nVirtualWidth;

	return nVirtualWidth - (nVirtualWidth - percentVisible);
}

The number returned is just passed to a SCROLLINFO structure and then to SetScorllPos()

Can someone please help me with this...the math part mostly but maybe i'm not understanding the nPage property or something...

if the nMax is 100 and nPage is 100 also...the thumb size is 100% meaning no scrolling can occur...I thought it was pretty self explanatory...

Help me please before I go insane... Poke tongue | ;-P

Thanx

cheers

You're actually returning percentVisible here. Is that what you want to achieve?

I'm trying to calculate and return the value needed to display proportional thumbs inside scrollbars...

The function takes as arguments
1) The virtual size of the window or DC
2) The visible size of the client area

I think these are the only parameters needed to calculate the thumb size...???

Just a few things i want to say about your posted code:

1) The first line inside the function reads:

if(nVirtualWidth <= nVisibleWidth) return -1;

But the declaration of the function is UINT, so it will return 0xFFFFFFFF. I assume you know this.

2) Second line inside the function:

float temp = ((float)nVisibleWidth / (float)nVirtualWidth) * (float)nVirtualWidth;

This long line does nothing other than:

float temp = (float)nVisibleWidth;

You first divide and then multiply the result with the same value you divided with?

3) Third and last line:

return nVirtualWidth - (nVirtualWidth - percentVisible);

For this you can simply write:

return percentVisible);<br />
<br />
This code seems to be improvable ;)<br />
<br />
:-D<br />

Thank you...I was wondering the scroll bars were hiding themselves automatically...I totally missed that one. Blush | :O

What can I say I hate math so very much...

What steps are required then in calculating the proportional thumbsize of a scrollbar...

I supply the function

1) The virtual width
2) The visible width of client

these two variables should be more than enough to calculate the thumb size no...?

Thanx

WM_DROPFILES vs IDropTarget

Hi,
I wrote a WinAPI (no MFC) app that implements IDropSource and all neccessary interfaces. I needed my app to support drag & drop. But I stuck with the WM_DROPFILES for the target, because it's way easier. But now, I'd need to accept both MOVE and COPY drops. As it seems WM_DROPFILES can't handle this (if it can, tell me!!), I'll need to do the IDropTarget interface implementation. Anybody could post some sourced to guide me? I know that I'd never write the IDropSource without the MSDN source, but I cannot find any on IDropTarget. Thanks

Problem with multiple acitvex instances on Win9x

I'm trying to have several instances of the same activeX embedded in a container application. This activeX is quiet complex, using message queues and graphic displays. If there's no problem on Win2000, NT or XP, the container application crashes on Win95/98/ME when it instantiates the second instance of the integrated ActiveX.
Does anybody have a clue what's happening ? (TIA)
