alpha generally ignores the bottom layer. alpha usually only applies to the top image, it controls overlay transparency and the bottom alpha is unchanged by the overlay image.

Surely you must consider the alpha values of all images in the stack if there's a background layer?

just merge each layer onto the background, one at a time, in Z order.

For eons, I have been creating my start menu links and desktop icons using IShellLink. I have found a serious limitation (for me) though - it does not work very well if trying to create links on a different machine (e.g., a UNC path.)
Is there any way to create a shortcut without using IShellLink? Is the .LNK file format documented anywhere?
OR perhaps there is another way arond this - since my problems are limited to creating shell links on network machines, is it possilbe to create a "dummy" shortcut locally, then copy the .LNK to the remote machine? I can't assume the target file I want to link to will be on the local machine though, it may only be on the remote machine.
Thanks!

You can use SHAddToRecentDocs for instance. Here[^] is some code.

THanks, althuogh from looking at it, it seems like it will suffer from the same problem I am having with IShellLink... namely, it doesn't look like it will work very well when creating shortcuts on a different machine.
I will investigate, though. Thanks for the info.

I am writing an application to grab images from a still camera (probably USB) using Visual C++ 6.0.
Most of M$ references are to .NET and windwos XP (I use Win2k).
Any suggestions ?
Thanks.

From my Visual C++ Dialog program I need to execute a Quickwin console program, and make it close automatically (under Windows NT).
The problem is, that when the program finishes it displays a messagebox with "Program Terminated, Exit Windows?" with YES/NO buttons.
Is it possible to get this window to close without the user having to press the Yes button?
I've used 'CreateProcess' to run the progam, so that I get the process handle, and was then going to
WaitForSingleObject(process, INFINITE);
CloseHandle(process);
The problem is that whatever I try, I always get the MessageBox - I never get past the 'CreateProcess' to be able to delete the window.
Cheers
Mike

It sounds like your Quickwin program is doing something weird. Have you tried ShellExecute() ?

Hi guys
Does anyone know how to translate this Matlab code into C++?
function a = fit_ellipse(x,y)<br />
d = [x.*x x.*y y.*y x y ones(size(x))];<br />
s = d'*d;<br />
c(6,6) = 0; c(1,3) = 2; c(2,2) = -1; c(3,1) = 2;<br />
[gevec, geval] = eig(s,c);<br />
[negr, negc] = find(geval < 0 & ~isinf(geval));<br />
a = gevec(:,negc);
i've done up until line 4 but i got stuck on solving the eigenvalue. Can somebody help me please? Thank you so much

See Robert's matrix c++ public domain code
http://www.robertnz.net/nm10.htm
You might also want to get a copy of "Numerical Recipies in C++" It has a really excellent discussion of various algorithms including eigenvalues/vectors.

Can anyone please tell me how to use _Worksheet::PrintOut() method to print excel file.
I tried to set the printArea and print the excel file out as follow;
<br />
_Worksheet sheet;<br />
COleVariant covTrue((short)TRUE),covFalse((short)FALSE),covOptional((long)DISP_E_PARAMNOTFOUND, VT_ERROR);<br />
<br />
PageSetup pg = sheet.GetPageSetup();<br />
pg.SetPrintArea("$A$!:$H$25;$A$45:$H$60;$J$80:$Z$100");<br />
sheet.PrintOut(covOptional, covOptional, covOptional, covOptional, covOptional, covOptional, covOptional, covOptional);<br />
the nothing got printed..
Am I using PrintOut in wrong way??
Thank You

Try using the sheet.GetPageSetup() function.
It will give you the Page Setup object and you can use SetPrintArea() from there. I also had trouble getting SetPrintArea() to work from the sheet itself.
Hope this helps...

How can I overwrite the drawing function of the Windows shell to customize the appearance of the desktop and its icons? I guess i should use system-wide hook but i don't know how...

I wondering what a class is and how you use it and what it does. Thanks
|

do you know how to declare the variables types?
for example.. int a; int is a class object or name ( in simple way to say it). You can create your own variable types like int . Your own types could be anything, blablabla, hehehe, employee, newYork, etc
<br />
class newYork<br />
{<br />
};<br />
<br />
Is that what you want to know??

hi
please read one c++ book atleast and then ask the questions..
CodeTheDreams();

It is a custom datataype in C++.

A class is the declaration of an object.
Let's imagine a button; a button have a color, a text, sometimes an image, and a function that gets signaled when the user clicks it...
A button is an object.
The declaration of a button would be (in easy terms) :
class CButton
{
COLORREF color;
CString csText;
CBtimap bmpImage;
void Onclick();
}
OK, now you have that class declarated, and now it's the time to use it in your code.
In your code you can instantiate (once you have your class declared you can define it everywhere where it is known).
Each time you need to use the class (the button in this case) you'll be declaring objects of that class (instantiating them) in this way:
in the Header file of your XXX dialog you could write:
...
private:
CButton m_mybutton;
...
and in your dialog initdialog function:
...
m_mybutton.color = 12344;
m_mybutton.text = "hello"
...
...
ow it's time to read a book of cpp and to learn how it really works, but this should be a good starting point...
Hope this helps.

I'm trying to mimick the 'arrange icons by...' as seen in explorer in my CListView based app.
I've looked up the method to implement this on msdn and have implemented my sort routine. So far so good...
The problem I have is that in mY sort function (compare function) I always receive the first record (0) of my listview to compare.
Some code snippits to explain:
void CMylistView::OnViewBydescr() <br />
{<br />
<br />
CListCtrl* m_cListCtrl;<br />
m_cListCtrl=&GetListCtrl();<br />
m_cListCtrl->SortItems(SortFunction, (LPARAM)(m_cListCtrl));<br />
}
int CALLBACK CMylistView::SortFunction(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort)<br />
{<br />
CListCtrl* pListCtrl = (CListCtrl*) lParamSort;<br />
CString strItem1 = pListCtrl->GetItemText(lParam1, 0);<br />
CString strItem2 = pListCtrl->GetItemText(lParam2, 0);<br />
return strcmp(strItem1, strItem2);<br />
}
