#include <iostream>
#include <strstream>
using namespace std;
int main(int argc, char* argv[])
{
unsigned x;
ostrstream stream;
for (x = 1; x < 10; ++x)
{
stream.seekp(0);
stream << "%%" << x << ends;
cout << stream.str() << endl;
stream.rdbuf()->freeze(false);
}
return 0;
}stream.str() calls freeze(true) to lock the buffer, I have to call freeze(false) to unlock it. Why your code worked without it is a mystery to me.

This should work too...
stream.str() = "";
But as you had another solution, nevermind.

write a program that stored the total cost of 4 items in a grocery
store.
a. write a function to input the total cost into the array. the cost
entered should always range between 20000 and 40000.(check this
condition)
b. write a funcion to output the details.
* calculate the GCT for each item. (Note :-GCT is 20% of Total
cost). Also calculate the Net cost of each item (Note: -Net cost =
Total cost - GCT)
* finally print the Total Cost, GCT and Net Cost in a proper
tabular format.
please anyone.. your help is needed... any help is appreciated,..
thank you....

You should ask a specific question! What have you done to solve these problems? Are you new at programming?
|
|
|
|

ok. thanks for replying. and yes i'm new at programming. its my 2nd week in class and i dont really understand the whole basic thing of c++. thats why i would like someone to at least do that question and i'll try and understand it.

You won't learn anything unless you actually try to solve the problems yourself. People will help you more if you attempt to solve it on your own.

thats true.. i think i would have a better knowledge of the subject if i understood the basics more. thaz my main problem. and i really like the whole topic of programming. i just want to understand it more and more. thats why i'm trying to get as much help as i can.

Look, just try it on your own, and when you get stuck with something, look on Google for that part that you got stuck on... If you don't find anything, then come here and ask us. That's what I do, and it works!

I guess this assignment goal is to reinforce what you have learned. What don't you specifically understand about programming C++?
|
|
|
|

how to use the signs and symbols. that is my main problem and that leads me to not knowing what to do at times.. i would really like to find out or get to know more abou programming.

That tells me you need help with the basics. You need to read your textbook from the beginning and seek a tutor. Also, typing and compiling sample programs helps. Modifying sample programs is a great help. There's a lot of information on the web that explains basic concepts. This forum is not the best place to get the information you seek.

Hi!
I've migrated a project from VS2003 to VS2005 and since then the application doesn't have XP themes anymore. What do I need to do to fix this?
Thanks!

I don't know, if the following, will be helpful! If you go to the project's property page under "ConfigurationProperties", you will find "Manifest Tools".

Hello everyone! 
Remember my previous post? I think I almost got it now!
New problem: I'm reading a file with this:
char * curLine = new char[WIDTH/32];<br />
f[x]->getline(curLine, WIDTH/32);
This is my file:
<br />
ABCDEFGHIJKLMNO<br />
PQRSTUVWXYZABCD<br />
EFGHIJKLMNOPQRS<br />
TUVWXYZABCDEFGH<br />
IJKLMNOPQRSTUVW<br />
XYZABCDEFGHIJKL<br />
MNOPQRSTUVWXYZA<br />
BCDEFGHIJKLMNOP<br />
QRSTUVWXYZABCDE<br />
FGHIJKLMNOPQRST<br />
UVWXYZABCDEFGHI<br />
JKLMNOPQRSTUVWX
I'm outputting what my program reads to another file, but that file comes out a bit different when I open it with SciTE... It shows me some "NUL" character at the beginning of each line starting at line 2, and 1 character at the end is moved to the beginning of the next line, and that number increases by 2 each line... Am I reading my file wrong? Maybe it's a different number from WIDTH/32? (WIDTH/32 is 16, the number of characters per line). Sorry for bothering you guys so much about this... But thanks!

Strings in C are NULL-terminated. You must keep this in mind so as to allow room for this terminating character when reading in and writing out string data.
For instance: you're missing the last character of each line, because your buffer is one character short.
Then you're writing out NULLs, because you write out the terminating character with the rest of the string.
Grab your textbook or Google, and look up C strings - get a handle on how they work before you end up tromping all over memory.

Seems theres no dummies steps out there for me..
Heres what I do:
1) On dialog view I click on the main form, in messages I goto WM_KEYDOWN, type in method name OnKeyDown and push enter.
2) In the OnKeyDown method I type in
AfxMessage("key pressed");<br />
SetWindowText("New Text");<br />
None of these changes occur when I press a key.
What basic thing am I missing?
And when overriding methods such as OnOk, do I just use the add function wizard and do it as a protected method in my code?
Thanks,
Brian

Hi
Actually the problem is when the dialog box is displayed it must have focus on any of the control. And when you press any key the WM_KEYDOWN goes to that control. If there are no control in your dialog box then your code will work.
Now what you can do to get that message is make the controls notify to the parent. But if there are lots of control you have to do it for each, and so its not a good idea.
Better you handle at PreTranslateMessage or WM_COMMAND to do your needs.
Regards
Anil

thanks, I used the PreTranslateMessage method you mentioned, and looked at the following site for how to basic steps to override http://support.microsoft.com/default.aspx?scid=kb%3BEN-US%3B817372[^]
then use
<br />
if (pMsg->message == WM_KEYDOWN){<br />
if(pMsg->wParam == VK_RETURN){<br />
return true;<br />
}<br />
}<br />
inside the new method.
thanks,
Brian

Hallo to all,
is there anyone who works with Dialogs and modless windows in DLL over MFC? How can I handle the right resources? What kind of DLL is to use? If it is possible, I want to use a Win32-Project with MFC as Console-App. Is it possible?
Thank you
Meinhard

Hi
What I got from your question is that you want to develop a DLL which supports Dialog box and it can be used in console and other application.
If it is so then it is possible. Use class wizard (MFC AppWizard (dll) ) to create your DLL. you can create dialog bos and all you want like MFC applicatin, and also you can use this DLL in console application.
Regards
Anil

Hi Anil,
I tried to do so, but if I want to acces it from the app like
CDialogXX m_dialogXX;
m_diologXX.create(ID_SOURCE, NULL); // ID_Source is a resource of the DLL
// but #defined in both identical.
the AFX_FindResource()-Function will abort.
TRhats my problem.
Thank you for helping
Regards
Meinhard
