Well, you have put zero in all of the array values. What do you need now?

Study these two statements carefully. What does it look like they are doing? Do you see anything that would look like it would produce the "chart" you are after?

Give this a try

int test_score[4][4] = {
    {0, 0, 0, 0},
    {0, 1, 2, 3},
    {0, 2, 4, 6},
    {0, 3, 6, 9} };

...
    cout << test_score[i][j] << ' ';
...

you need to replace the line

test_score[i][j] = 0;

with a formula that will give the chart in the answer

for example test_score[i][j] = i + j;

would give

0 1 2 3
1 2 3 4
2 3 4 5
3 4 5 6

think about it.

Hello, i have a problem to set new font for that list control!
I use SetFont(newfont); and the execution go to
OnSetFont(WPARAM, wParam, LPARAM lParam)
{
...
SendMessage(WM_WINDOWPOSCHANGED, 0, reinterpret_cast<lparam> (&wp));
...
}
after this execution should call
MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
but program newer go to MeasureItem!

Any idea how to solve this?

WM_WINDOWPOSCHANGED is a notification message sent by the system. It is unrelated to setting
the font and you shouldn't be sending the message yourself.

Why do you think MeasureItem should be called? And more importantly, WHOs MeasureItem()?

Right. But this has nothing to do with setting the font and you shouldn't be posting that system
message.

If you want to redraw the control with the new font then you should invalidate it.
MeasureItem will be called automatically by the system when it needs sizes for the redraw.

You need to include "ws2tcpip.h" (this is stated in the documentation).

How to return parameters from DLL ?

Hi All,

I have developed an HTTPS request DLL. I want to return the headers and message body to the calling application. The prototype of my DLL function is int. How can I pass the returned headers and message body ?

Please help me.

Thanks for your prompt reply.

Oh yes, a bit contrived yet. If you function returns a 32-bit integer then you can interpeter it as a pointer (at least on 32-bit systems...). That stated, you may arrange the two buffer pointers in a struct and return the struct address to the caller.
However, IMHO it's better to change the function prototype.

AFAIK Cygwin is a Unix-like env where you can run standard windows executables.

Well, if you have the development tools installed, then you can use gcc (or g++ for c++ projects) to create the executable for simple projects. If the project is complex, probably you have to create a makefile. AFAIK there are also some IDE's that can be used with Cygwin, for instance DEV-C++ [^].
