Please do not post the same question in more than one forum; select one and stick to it.

What does this mean? We have no way of guessing what you are referring to here. Does your code compile successfully, do you get an error, exception, system crash ... ?

And you still believe I can guess what's wrong?

My guess is that he compiled/linked his application fine but it didn't work on other computers... applications developed using VC2008 would most likely require .NET framework to run, make sure your clients have .NET framework installed on their own machines.

In general, the forms in your SDI application should represent some part of your model (the document class). In general, you should avoid direct "comunication" between two forms but one form should update the document which in turn notifies all the views that its state has been updated. The other views can then request the new state of the document and update themselves.
On the other hand, if you really need direct access between the two forms, then this simply resolves to OOP: you just past the instance of one form to the instance of the other form. But if possible, you should avoid this solution.

you should disconnect data (and its processing) and view. Than you show the data in the views, and handle the "data changed" message to show actual data.
It gives you flexibility to change you GUI later

How to load swf from resources? any tutorial or steps ?
There are functions to load icon and dll but what to do with swf.
Is it possible?

You can get a resource into memory (as if you'd read it from a file) like this:
std::vector<BYTE> LoadFileFromResource(HINSTANCE hmodResource, LPCTSTR name, LPCTSTR type)
{
if (!type)
type = ::PathFindExtension(name) + 1;
HRSRC rsrcFile = ::FindResource(hmodResource, name, type);
if (!rsrcFile) return std::vector<BYTE>();
HGLOBAL gblFile = ::LoadResource(hmodResource, rsrcFile);
if (!gblFile) return std::vector<BYTE>();
DWORD sizeFile = ::SizeofResource(hmodResource, rsrcFile);
if (!sizeFile) return std::vector<BYTE>();
LPVOID filePointer = ::LockResource(gblFile);
if (filePointer)
{
return std::vector<BYTE> contents((BYTE*)filePointer, sizeFile);
::FreeResource(gblFile);
return contents;
}
return return std::vector<BYTE>();
}
I take a copy of it here, to make resource management easier, but you don't have to do that...

YOu can also use the res://[^] protocol, which basically gives you an URI for the resource element.

Hello folks!
I have a few layered windows which use per-pixel alpha of 32 bit bitmaps to display graphics. I use WindowFromPoint and TrackMouseEvent (which probably uses WindowFromPoint also somewhere along the way of its processing but that's just a guess) to know when the mouse points at these windows. Now, here comes the catch, WindowFromPoint takes the alpha channel of layered windows into acount (also TrackMouseEvent does this when listening for mouse-leave events), so when the given point (e.g: mouse position) is above a transparent pixel of the window then it will ignore the window. This is very good that way 99.9% of the time. However, i would need WindowFromPoint and TrackMouseEvent to handle my layered windows as if they were not layered windows, so they were normal, everyday, non-transparent rectnagular windows. Is this trick possible somehow? I know i could just forget about these methods and try to write my own implementations, enumerating windows, checking Z-orders and so on to try and find the "pointed" window, but it is probably quite a hassle to implement and would probably turn up a lot of "i didn't think of this" cases when it fails.
Thanks in advance for any comments, ideas, answers.

Hey, thanks for the suggestion, however, my layered windows are popup windows, not child windows (as far as i know you can't have layered child windows at all), and i believe the CWP_SKIPTRANSPARENT flag of ChildWindowFromPointEx refers to the WS_EX_TRANSPARENT window style rather than any transparent pixels in the window. Correct me if i am wrong.

Hi,
Well popup windows are usually children of the dektop window so that really isnt an issue. I just did a quick test with one of my applications splash screen and was able to use ChildWindowFromPoint to find my popup splash using the desktop as the parent. The bad news is that I confirmed your suspicion about WS_EX_LAYERED windows with an alpha. ChildWindowFromPoint did not find the window when I hovered over transparent regions.
Best Wishes,

I thought of doing the following: I call WindowFromPoint, if it returns one of my windows then the case is clear, if it does not, then i enumerate my windows, check if the point lies inside their window rectangles, if i find one then i check if the window WindowFromPoint returned is above or below my window (in Z-order i mean) and if it is below then i assume the point is in my layered window, otherwise not. This involves finding the popup that contains the window WindowFromPoint returned in case it is not a popup itself, i guess that can be done easily unless GetParent and GetWindowStyle (GetWindowLong and GWL_STYLE) does not work for windows of different processes (have to check that)...
What do you think? Thank you for your oppinion. 
Sadly this does not solve the TrackMouseEvent problem...

Hi,
Sorry about the long reply delay. Today is Sunday and I am being very lazy.

Well in my opinion you should find a solution which addresses both issues. Have you tried the following?
POINT p;
GetCursorPos(&p);
LRESULT r = ::SendMessage(aboutDlg->m_hWnd,WM_NCHITTEST, 0,MAKELONG(p.x,p.y));
I tested this on a splash screen which is WS_EX_LAYERED and has an transparent alpha color key. The WM_NCHITTEST is returning HTCLIENT for anything inside the window rect *including* transparent region.

I tested this, but this kinda works the same "is the point inside the rectangle" way and it will return HTCLIENT even if the window is overlapped by another one, so if there is a window covering the one i test for and the point is inside its window rectangle it will report HTCLIENT althorough the mouse points at a different window.
I guess i will have to rethink the way i want to implement this, forget about TrackMouseEvent and either use a global mouse hook to track the nouse's position, use a timer to periodically poll the position (i personally dislike polling) or use SetCapture when the mouse enters a window so i can track where it goes and notice when it leaves. For the hit-testing i probably will try the WindowFromPoint + check Z order + check rectangle (WM_NCHITTEST for that seems to be a good idea, thanks) "trio".
A simple aproach to the problem which works both for WindowFromPoint and TrackMouseEvent is to change all the alpha values in the bitmaps that define the layered windows to be at least 1 (so no zeroes, no completely transparent pixels), as it seems hit testing by windows with layered windows is based ont he alpha pixel value, if the pixel has a 0 alpha value (completely transparent) then there's no hit, otherwise there is. I just don't know how reliable this method is and also if it can produce any noticable visual anomalies (a "ghosty" rectangle around the bitmap"). For now i will just take this for simplicity, althorough i don't much like it...
