You cannot add a WORD type to a constant string.
Use the Format method of the CString class to generate the Text for the MessageBox.

Thanks,CPallini.I still get the same values when I include your example. However, when I run in debug mode and examine the values, I can see the SYSTEMTIME.wMilliSeconds. Just don't seem able to access it in a messagebox.

I made a test, my code works on my system.
Could you please post your updated code? Are you doing a UNICODE build?

Thanks CPallini - Just don't seem to get a sensible output. I've omitted your code for reasons of clarity.
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
SYSTEMTIME st;
PAINTSTRUCT ps;
switch (message)
{
case WM_PAINT:
{
HDC hdc = BeginPaint(hWnd,&ps);
EndPaint(hWnd,&ps);
}
return(0);
break;
case WM_KEYDOWN:
{
SYSTEMTIME st;
GetSystemTime(&st);
//get duration in milliseconds
}
break;
case WM_TIMER:
{
}
break;
case WM_KEYUP:
{
SYSTEMTIME st;
GetSystemTime(&st);
//get duration in milliseconds
}
break;
case WM_DESTROY: // onload from memory
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
}

Are you doing a UNICODE build?
What is msg value at runtime, after the StringCbPrintf call (use the debugger to see)?

Thank you so much CPallini for you contribution. I made a small change to your original code by changing _T to L"" and it worked.
Below is your code that I made small changes to.
HRESULT hr = StringCbPrintf(msg, sizeof(TCHAR) * BUFSIZE, L"Time is %d", st.wMilliseconds);
So I suppose all that's left is to ship that crate of cool beer to ya as promised in my original post.

My function that call UpdateLayeredWindow work well when I use Window DC.
But when I try to use new memory DC that is created with CreateCompatibleDC function and Window DC, UpdateLayeredWindow return error code 8.
This so strange. How should I use memory DC to draw over Window DC using UpdateLayeredWindow function ?

basically i am in need of dire assistance i created this code, but i can not seem to get it to pick up the smallest inputted integer, so if someone could help me, i am a nub and would be most apprciated. thanks!

int smallest = 0;
if (j < smallest) { smallest = j; }
Have a look at those 2 lines, and think a little bit more about what is going on.
If you're not certain, just "run" your program on paper. (yeah, pen and paper).

{
int i = 0;
int j,totals,x;
double avg;
int k = 0;
int largest = 1;

this is the code i currently have i wrote it out and thought i need j to be the standard input, then i would want if smallest is greater than j i would want the smallest to be j then if j was less then smallest i would want it to be replaced, i dont know if i explained that well but thats what i have so far...

You should really indent and beautify the code.
It make very easy for another person to look at.
This is not at all readable.

ok so i got it to this:
[code]
// ints.cpp
#include <iostream.h>
int main ()
{
int i = 0;
int j,totals,x;
double avg;
int k = 0;
int largest = 1;
int smallest = 99;
int l;
do
{
cout << "Enter a number (enter zero to exit): ";
cin >> j;
i = i + j;
k = k + 1;
if (j > largest) {largest = j; }
if (j < smallest) { smallest = j; }
}
while (j != 5);
totals = k - 1;
avg = double(i) / (double(k) - 1);
cout << "\n\n\nThe number of numbers is " << totals << endl;
cout << "The average is " << avg << endl;
cout << "the largest number is " << largest << endl;
cout << "The Smallest Number is " << smallest << endl;
cin.ignore(5);
system("PAUSE");
return 0;
}
[/code]
which works but the problem being i need to ignore a ZERO ( 0 ) instead of a 5 :-/ but whenever i put a 0 as the stopping then it doesnt work...
|
|
|
|

Did you mean it doesn't work if you put 0 in place of 5 here - while (j != 5);?

exactly if i change
while (j != 0);
cin.ignore(0);
to
while (j != 5);
cin.ignore(5);
the program works, but problem being is i need the number to be 0 to end the program...

1/ Please use the code block formatting, and the preview button - you'll be amazed how much easier your code is to read.
2/ As suggested, run your program with a pen and paper. You'll be surprised how much it helps.
3/ I'll give you a big clue you're already been given.
int smallest = 0;
if (j < smallest) { smallest = j; }
3a/
Think about how many numbers are smaller than zero. Are the numbers you've entering small than zero?
Changing it to 1 only makes things better than one.
3b/ You'll have the same problem with largest, if you type in all negative numbers.
Enjoy,
Iain.

Initialize smalltest to the largest 4 byte integer :
int smallest = 4294967295 ;
if (j

*I* know that... though I'd recommend using MAX_INT...
But I was trying to lead the obviously a homework question in the right direction.

Hi
In my MFC dll I have this code in function:
HINSTANCE hInstance = AfxFindResourceHandle(MAKEINTRESOURCE(iID), RT_RCDATA);
return ::PlaySound(MAKEINTRESOURCE(iID), hInstance, SND_RESOURCE | SND_ASYNC | SND_NODEFAULT);
wave file is in resource of the dll, but when I call it from the exe, it can't play it, because it can not find it, (there is no RT_WAVE type!)
how can I play a wave file that is in a dll file?
Thanks

Hi,
I have a Multiline Dialog Box would anyone have the sequence
of Win32 SDK API calls to calculate/set the number of characters in a
Line of a Multiline Dialog Box
BTW I am using Rich Edit 2.0 though I don't think this has any
bearing on my question
|
|
|
|
|
i guess it's done automatically
Don't try it, just do it! 
|
|
|
|
|
what about CRichEditCtrl::GetTextLength() ?
how dumb of me... shoulda read the whole thing.
what about getting the whole text and looking for CR-LF and counting the characters between them ?

I am using Plains old C so EM_LINELENGTH
But if I cann't fit the Number of Characters I want on the Line
I would to some how want to make the font smaller ???
I guess I shoud re-prhase the question if I for Instance want 12
characters on one line of a MultiLine Dialog Box How Can I
calculate/set the right Font ??
