I need help deciphering how to use manipulators to put together this output statement correctly. (setprecision, setw, right...etc.). This is just one small part of my homework, but if I can see this worked out I should be able to put the rest together myself. My professor has no  communication or teaching skills and leaves me confused. 
Output fourth with four digits, with the sign shown at the left, and the value right aligned. The decimal point must also appear.
Here is the program my professor is having us go by:
cout << "Enter bool, int, long, float, float, and double values: ";
cin >> first >> second >> third >> fourth >> fifth >> sixth;

ok, we understand the pain ...but what have you tried so far Sarah ?
We try not to do people's homework by just giving them an answer - copying and pasting isnt going to help you learn, is it ?
So, Im going to give you the start of the answer ...
cout << setprecision(x) << fourth << endl;
Why dont you type it in, (note, you need to replace the (x) in setprecision with a number - think carefully, or just try multiple output statements), compile and run it ..
Its probably bad form to have the 'using namespace' clause below, but for testing something quick, Im going to close my eyes and just do it the simple way, so, you'll also need
#include <iostream>
#include <iomanip>
using namespace std;
at the top of your program.
try it ...

Thank you this is what I was asking, just a start because I have litterally never written code in C++ only pseudocode. I am just trying to put together how each line will appear. He provided the entire program we have to fill in our solution. Here, I'll show you...
Exercise 3:
Objectives: using the iomanip library to format screen output.
Complete the provided main() program with statements to accomplish each of the following. In each case you must use the appropriate I/O stream manipulators to produce the appropriate output wherever possible. Refer to the sample output below as a guide for proper output alignment.
Output first first as an integer value, followed by a space, then in its written form.
Output second as a base ten value, followed by a space, then as a hexadecimal value, followed by a space, then as an octal value. Make sure the appropriate base indicator prefix is shown in the output.
Output third.
Output fourth with four digits, with the sign shown at the left, and the value right aligned. The decimal point must also appear.
Output fourth with four significant figures.
Output fifth with seven significant figures. (Must be left-aligned)
Output fifth with three digits to the right of the decimal point.
Output third.
Output fourth with two digits to the right of the decimal point.
Output sixth with no decimal portion showing
Output fourth with eight digits to the right of the decimal point.
Output sixth with six digits.
You must start your coding by using exactly the following program. You may not modify it, except to add the required code between the Solution starts, and Solution ends comments.
#include <iostream>
#include <iomanip>
using namespace std;
int
main()
{
bool first;
int second;
long third;
float fourth;
float fifth;
double sixth;
cout << "Enter bool, int, long, float, float, and double values: ";
cin >> first >> second >> third >> fourth >> fifth >> sixth;
cout << endl;
// ***** Solution starts here ****
// ***** Solution ends here ****
cin.get();
return 0;
}
SAMPLE PROGRAM OUTPUT (assume user inputs values shown in bold):
Enter bool, int, long, float, float, and double values:
1 69 1464878 6443.39 -7.273 -6443.39
1 true
69 0x45 0105
1464878
+ 6443.
6.4434e+03
-7.2729998e+00
-7.273
1464878
6443.39
-6443
6443.39013672
-6443.39

ok, I suggest you comment each section you're working on, between the
Sarah Trattner wrote: // ***** Solution starts here ****
marks, it'll make it easier ... so it'll look like
cout << something << first << " " << something-else << first << endl;
cout << third << endl;
But you'll see in Part 1, Ive deliberately used 'something' and 'something-else' ... ok, so, you're outputting a boolean value - you need to pick the two flags that work particularly well with booleans, and, there's an obvious hint - one starts with 'bool' .. once you find the flags - they'll be in your notes for sure, put them into the statement .. you'll also see Ive commented out the start for Part 2 - you can comment lines out that you're experimenting with or jotting down ideas, so that if they are wrong, your program will still compile ..
do you follow so far ?

|

btw - commenting skills are a MUST .. I cant teach you your own style .. but consider each of these
cout << something << first << " " << something-else << first << endl;
and
cout << something << first << " " << something-else << first << endl;
which is easier for someone else to read ?

Is it required to add the BOM code (BOM = 0xFeFF) at the beginning of a .txt file in order for it to be opened as a UNICODE one, by notepad?

I'm writing a program to display multiple images on character select:
my code is on
case WM_CHAR:
{
switch((char)wParam)
{
case 'A': case 'a':
hbmp = LoadBitmap(hInst, MAKEINTRESOURCE(IDB_BITMAP2));
break;
case 'B': case 'b':
hbmp = LoadBitmap(hInst, MAKEINTRESOURCE(IDB_BITMAP3));
break;
case 'C': case 'c':
hbmp = LoadBitmap(hInst, MAKEINTRESOURCE(IDB_BITMAP4));
break;
default:
break;
}
}
break;
case WM_PAINT:
{
hDC = GetDC(picBoxDisp);
MemDCExercising = CreateCompatibleDC(hDC);
SelectObject(MemDCExercising, hbmp);
BitBlt(hDC, 0, 0, 200, 200, MemDCExercising, 0, 0, SRCCOPY);
DeleteObject(hbmp);
DeleteDC(MemDCExercising);
SendMessage(picBoxDisp,BM_SETIMAGE,IMAGE_BITMAP,(LPARAM)hbmp);
Images are displayed correctly but second image overlapps first...
|
|
|
|
|
DeleteObject(hbmp);
DeleteDC(MemDCExercising);
SendMessage(picBoxDisp,BM_SETIMAGE,IMAGE_BITMAP,(LPARAM)hbmp);
You are sending a handle to a deleted object in the last line of this code. What does the recipient of this message expect to do with it?
|

That doesn't explain the images overlapping. The overlapping might be a result of none identical size of the images.

Hello Friends
I am creating a MFC application using VS2010 on WinXP.
i am using CFileDialog with Preview functionality while opening a file.It is working Fine in WinXP but in Win7,it is not showing any preview.
Do i need to change in MFC header Files? As I Found that,we need to chahnge #define WINVER to 0X501 from 0X00600. But I didnt get any clear result.
Any Ideas?
Regards
Yogesh Sikri

Version for Windows 7 is 0x0601, but that will not necessarily fix the problem. I'm also not sure what you mean by Preview in this context (not used MFC for a while).

|

I derived class CFileDialog and Customize File Open Dialog by adding Preview option in OpenDialog[flags used OFN_ENABLETEMPLATE].
But this is not working in Win7.
I found on net tht we need to use Common File Dialog to Customize open File dialog in Windows7. But there should be way for Existing Applications which is using CFileDialog.
Regards
Yogesh

Then you need to debug your custom code.

I debug My Code In Win7 too and its working Fine. The prob is tht Open Dialog in Win7 is not resizing.Then Only Preview Window will Appear.How can I Achieve that ?

This may be in the wrong forum – but here goes.
I have a 32-bit application that I've been maintaining for about 12 years and it runs on every Windows platform up to Windows 7. In all that time I've been using CWinApp::GetProfileXxxx() and CWinApp::WriteProfileXxxx() calls to read and write my program settings (about 70 settings) in the Registry. The settings are read from the Registry at start-up and written to the Registry when the program closes. There is also a method for the user to read and write the program settings to an INI file using the same code as the Registry access.
On my Windows 7 system the Registry read/write works just like it always has on all previous Windows versions. However, on some customer's Windows 7 machines there appears to be a problem with the Registry access. The program settings are either not being read from the Registry or are not being written to the Registry. I think the settings are not being written – but I don't know that. When the user uses the INI file the settings appear to be read and written.
The customer has complained a bit (I'd complain too) but doesn't have the time or doesn't want to take the time to run some simple tests for me to find out what's going on with his Windows 7 system.
So here is my question: Are there any user account settings or permissions that can block the program's access to the Registry? He claims he is an Administrator but I can't even get him to verify that.
Thanks,
Mike

Yes, UAC can. It was introduced with Vista but changed somewhat with Win7. Turn it off and see if that makes a difference.

I don't think UAC is the answer. I looked at my UAC settings and didn't see anything other than how to set the warning levels. Mine is set to: "Default: Notify me only when programs try to make changes to my compputer". Even with this setting my program never causes the UAC to display the notification.
I think the problem lies in the Registry p0ermission settings, but I don't know yet.

You should be looking at the customer's settings, not your own. That's where the problem is.

I KNOW I sould be looking at the customer's setting. The problem is that I'm not getting any support from him.
So, I need to understand the settings on my computer so I can run some tests and make suggestions to him. My problem is that I'm not very well versed in "security" settings in Windows 7. I still think it is a user permission setting in Registrey - but I'm not sure where to look yet.

You should look into logging, just as a general programming idiom. With logging you would know, rather than attempting to guess, what was happening.

Well, this is what I have found so far.
The Registry key permission setting does indeed stop my program from writing to its Registry key. On my two WinXP and my Win7 systems the Registry key permissions are set to "full control".
Registry editor does not allow me to manually change the "full control" permission to "Read". The "full control" permission is checked but disabled (dimmed) so I can't change it and I don't know why. I had to find a utility that changed the permission outside of registry editor. When the key permission was changed to "read" then writing to the Registry failed.
CWinApp:WriteProfileInt() fails with a "read" permision but there is no error code associated with the failure (i.e. GetLastError() doesn't return an error code).
I think the only thing I can do is detect the Registry write failure, report it to the user, and use an INI file instead of the Registry. I don't particularily like it but I think that's my only choice.
