Thank you.I got code for same on google!!

here is an algorithm that should do it, in pseudo-code:
char prev=0;
int count=0;
foreach(char c in the input) {
if (c!=prev) {
if (count>1) output(count);
output(c);
prev=c;
count=0;
}
count++;
}
It is a bit tricky, I suggest you study it first (test it by hand!), then implement it in C and test it again.

hi
i am trying to encrypting the existing file and folder using the zip archive lib.
here is the code
CZipArchive sar;
sar.Open(_T("C:\\1234.zip"), CZipArchive::zipCreate);
sar.SetCompressionMethod(CZipCompressor::methodBzip2);
sar.AddNewFile(_T("C:\\1234.txt"));
sar.AddNewFile(_T("C:\\sar1"));
sar.AddNewFile(_T("C:\\afzal.txt"));
but i want to do 1234.txt itself an zip file or directory ie existing not by adding the file or folder to a zip file .......
i studied encrypt file method i did't understood the code which they mention in the help file how to use it ..
is there any other way to encrypt it using the zip archive lib
plz help me out this
thanking you

Hi,
I am working Fodero eclipse c++. I have one unsigned char(one byte unsigned integer) variable.
i am passing some integer value. like
unsigned char aa= 10;
but aa is not assign that value? How to pass that value on unsigned char.
same like i am using unsigned long, i add 'u' on the end the passing number.
unsigned long bb= 10u;
here i got bb value is 10.
how to get unsigned char value?. Any ideas or link share to me.
please urgent
Regards,
M.Mathivanan

Sorry for not understanding: Is it the question that is urgent or the answer, or maybe both? Could you elaborate?

Your assignment looks valid. How did you test that aa does not hold the correct value? If you checked in the debugger, or pass it to cout, please remember that the type is still a character, and the standard representation is as a character. The value 10 is a non-prinitable character, and as such would show no visible output either in the debugger or in a printout, unless you convert aa to int first.

|
|

unsigned char aa = (unsigned char)10;
BTW: when you get build-time messages or run-time errors/exceptions, you should mention them verbatim in your question.

The statement is indeed correct. Probably the fault is in the way you check it.

You are getting a 10 as a binary value with that assignment.
If you use cout<< to print it out, however, you won't see a 10. That's because cout<< called on a char or unsigned char value always treats the value as a character, not a number. What you will see is that the next thing you output will begin on a new line. The 10 translates to a '\n' newline character.
To see the binary value of a char as a unsigned decimal value, use a typecast first.
unsigned char bb = 10;
cout << "** bb looks like [" << bb <<] this." << endl;
cout << "** (unsigned)bb looks like: " << (unsigned)bb << endl;
Which should display:
** bb looks like [
] this.
** (unsigned)bb looks like: 10
I put the unsigned char version in [] brackets so you can see what the effect is on the output.
Cheers,
Mike

how can i pass the values from child dialog window to parent dialog window. (ie) text box value and etc.., (how to use AfxGetApp())
Ex:
1).CTestdlg (parend dlg)
2).CDatadlg (child dlg)
i want to get data from the CDatadlg edit box to CTestdlg member
|

One way is to set the parent dialog pointer to the child window, after creating it. Use this pointer to call parent dialog's functions to notify or to directly set the values.
class CTestDlg;
class CDataDlg
{
.......
public:
SetParentDlg(CTestDlg* parent)
{
m_pTestDlg = parent;
}
private:
CTestDlg* m_pTestDlg;
}
From CTestDlg, after creating child dlg, call SetParentDlg(this) on it.
#include "testdlg.h"
......
m_pTestDlg->Function(data);
Also, you may use SetParent() and GetParent() functions on CTestDlg, and cast the returned pointer to CTestDlg* and use.
AfxGetApp() returns the CWinApp pointer, and you can cast this to your MFC application class and use.

Thanks "Cool_Dev" it works fine.

It may "work" but why would you want to "link" two dialog boxes together in this fashion? Having such a strong-coupling model is rarely a good idea.

1. Send a user defined message to GetParent()
2. Cast GetParent() to CTestDlg* and call a method / set a variable
3. Implement the observer pattern.
4. Use a callback function.
Any of those will do if you need to notify the parent dialog while the child dialog is still opened.

Hi,
I'm creating a brick game and am having trouble merging these two if blocks. They work independantly fine but not together. Any ideas on how to get them to work. They reverse the velocities of the ball when hitting a brick. I'm also having a problem where the ball sometimes goes through a brick, it flickers and slowly makes its way through,kinda glitchy.
if(Ball_List[b]->gameBall->Bounds.IntersectsWith(Brick1->Bounds))
{
if((Ball_List[b]->gameBall->Right >= Brick1->Left || Ball_List[b]->gameBall->Left <= Brick1->Right))
{
Ball_List[b]->xVel = -Ball_List[b]->xVel;
}
if((Ball_List[b]->gameBall->Bottom >= Brick1->Top || Ball_List[b]->gameBall->Top <= Brick1->Bottom))
{
Ball_List[b]->yVel = -Ball_List[b]->yVel;
}
}

You are using logical OR (||) instead of AND (&&). In the first case if BALL.RIGHT is greater than BRICK.LEFT OR BALL.LEFT is less than BRICK.RIGHT you slow it down. However you need both conditions to be true; for example if BALL.RIGHT is greater than BRICK.LEFT then you change velocity, but the ball is not necessarily less than BRICK.RIGHT at this point. I think the same holds true for the vertical movement.
