Include afx.h, but there might be others that you'll need to include. Here's the default includes for a dialog based app:
#define VC_EXTRALEAN // Exclude rarely-used stuff from Windows headers
#include <afxwin.h>
#include <afxext.h>
#include <afxdisp.h>
#include <afxdtctl.h>
#ifndef _AFX_NO_AFXCMN_SUPPORT
#include <afxcmn.h>
#endif // _AFX_NO_AFXCMN_SUPPORT

I have two files:
aa.txt:
20020102,23.0
20020103,23.0
.............
20030301,35
bb.txt:
20010101,22
20010102,25
...........
20021220,23.5
Now I want to append the latest datas ( from the "20021220,23.5" to "20030301,35") of the file "aa.txt" to the file "bb.txt".
How could I do ! Please tell me the easy way to do it!
The latest datas in the file aa.txt are the datas that are not included in the file bb.txt.
Note: i only want to append the datas that the bb.txt is not included.
I wrote the following:
Please help me ! what's wrong with the following;
while(fileDest.ReadString(strLine0))
//get the last line of the writed file bb.txt
{ if(strLine0.GetLength()>10)
{ strMax=strLine0;
}
}
while(fileSource.ReadString(strLine))
{
//get the line of the read file aa.txt is equal to the last line of the writed file
if(strLine.Left(strLine.Find(','))==strMax.Left(strMax.Find(',')))
{
//get the read position of the file aa.txt
theReadPosition=fileSource.GetPosition();
break;
}
}
// the term is true , then read line from the aa.txt
while(fileSource.ReadString(strTemp))
{
if(strTemp.GetLength()<10)
continue;
fileDest.WriteString("\r\n"+stTemp);
}
fileDest.Close();
fileSource.Close();

Hi guys,
I am trying to add double slashes in front of a string, I am wondering it can be done as below
Assuming both variables have contained some characters
char *FileString; // a pointer to character string
char Buffer[256]; // an array to 256 characters
FileString = '//' + Buffer;
Please advise,
Thanks alot

Use strcat()
-Nick Parker
|
|
|
|

strcat() won't work as it accepts only constant char* , which buffer[] isn't. It crashes the program upon that point.
e.g.
char string[200]
strcpy(string, "\\");
strcat(string, Buffer); <-- won't work here.
Any suggestions?
Thanks again

U can try like this.
CString strFileString;
CString strSlah("//");
char szBuffer[256];
strFileString=strSlash+szBuffer;

C-style strings don't work like that. You should be using std::string unless there is an overriding reason not to:
std::string FileString;
std::string Buffer = "some stuff...";
FileString = "//" + Buffer;

Thanks guys,
I tried not to use std::string as I am not sure if it's portable to Embedded Visual C++. I am doing the program using Visual C++ and expecting to make it workable on iPAQ when re-compling.

I'm struggling on this one... appreciate any hints you experts can offer.
Just trying to print out a histogram, using asterisks, to show the number of times each number 2-12 was rolled, after 50 rolls. I created the following two loops and cannot get the asterisks to continue to the next line as appropriate
<br />
max = maximum (frequency, arraySize); <br />
<br />
for (int countDown = max; countDown >= 0; countDown--)<br />
<br />
for (int j = 0; j < (arraySize-2); j++) <br />
<br />
if (frequency[j+2] <= countDown)<br />
cout << setw(3) << "*" << " ";<br />
<br />
else<br />
cout << setw(3) << " " << " ";<br />
<br />
<br />
for (face = 2; face < arraySize; face++)<br />
cout << setw(3) << face << " ";<br />
I tried adding an if statement---> if (j%10 == 0) cout << endl;
doesn't work.
Any suggestions?
Thanks so much!

When writing a for loop you need to use the curly braces when your statements within that for loop extend beyond 1 line. The two examples are the same, writing a new line doesn't occur until after the inner for loop has completed:
for(int i = 0; i < 10; i++)
{
for(int j = 0; j < i; j++)
{
cout << "*";
}
cout << endl;
}
or
for(int i = 0; i < 10; i++)
{
for(int j = 0; j < i; j++)
cout << "*";
cout << endl; <font color="green">
}

 I wanna use HOOK to catch the BM_SETSTATE message of a button，and i don't wanna return it to the button.i catch the BM_SETSTATE and did't return ::CallNextHookEx(hHook,nCode,wParam,lParam);
but the message is still pass to the button when i push "OK" of the Messagebox.
Pls. see my code here:
LRESULT CALLBACK CallWndProc(int nCode,WPARAM wParam,LPARAM lParam)
{
if(nCode != HC_ACTION)
{
return ::CallNextHookEx(hHook,nCode,wParam,lParam);
}
if(nCode == HC_ACTION)
{
pCwp = (CWPSTRUCT *)lParam;
if((wParam == 0) && (pCwp->message == BM_SETSTATE))
{
TRACE(childWinList[107].winText);
//MessageBox(NULL,childWinList[107].winText,childWinList[110].winText,MB_OK);
::SendMessage(pCwp->hwnd,WM_GETTEXT,256,(LPARAM) b);
CString a = b;
if (a == "Confirm Load")
{
GetWindowsList();
if (childWinList[107].winText != childWinList[110].winText+"_"+childWinList[89].winText)
{
if (!bShow) return -1;
bShow = 0;
if(IDOK == MessageBox(NULL,"The device Number and program name do not match!",b,MB_OK))
{
bShow = 1;
}
return -1;
}
}
}
}
return ::CallNextHookEx(hHook,nCode,wParam,lParam);
}

I'm developing an app in VC6 & MFC where I'd like to ship multiple versions of the software utilizing the same base source code. By multiple versions, I mean two variations of the same application. One version will be like a "Basic" version and another will be an "Advanced" version. So basically the same idea as Windows 2000 Pro and Windows 2000 Server. Both pieces of software utilize the same base code, generally speaking, but have different features available.
I'm looking for ideas, methodologies, approaches, design, etc. on how to implement this. Is the only answer preprocessor directives? What about some type of plug-in approach? The result needs to be able to modify the UI (menu bar, menu items, etc.) I've done a little research on the web but haven't found a "clean" approach to this problem. Help! Thanks

I'm using the DeleteFile Function in an attempt to delete the program that is running. How can a program delete itself? I tried renaming the executable before deleting it, and it does is rename it but doesn't delete it. I suspect you can't delete an open file or program in NT, but I'm sure someone here has found a way to make a program delete itself aka uninstaller..
Any help would be thouroughly appreciated. Thanks in advance friends!

The easiest way is to create a batch file (.bat), from your program, start the batch file and exit your program.
In the batch file you loop until you can delete the programfile, and you delete the batch file (it can delete itself, a running program can not)

Consider this function
copyString(char *dest , char *source)
The minimal code to perform this copy is
copyString(char *dest , char *source) <br />
{<br />
while(*dest++=*source++);<br />
}
which can also be written as
copyString(char *dest , char *source) <br />
{<br />
while((*dest++=*source++)!=0);<br />
}
Now consider two strings
dest = <undefined>;<br />
source="sensibleString\0...garbage;
How does the while loop override the asignment operator = and copy only till the source is '\0';
My question is that I need a reason for the loop not to be running infinetely
Doesn't the while loop keep running till the assignment succeeds ? i.e how are garbage values after '\0' not being copied into source ?
Please help me solve this doubt !

it doesn't.
in C/C++, the 'result' of an assignment is equal to the right side of the assignment.
in other words:
int a,b,c;
a = 5;
b = 10;
c = a = b;
so, the loop runs until the 'result' of the assignment is 0.

Remove the ";" at the end of the line of the while loop. There is not ";" after a loop.
while((*dest++=*source++)!=0)
{}
What do you have "0" instead of "\0" in the while loop?
while((*dest++=*source++)!= "\0")
{}

Hi All, wondering if someone could take a look at the following program and give me any hints/insight as to why I can't get the appropriate amount of asterisks to print above each number.
This program rolls two dice and is supposed to calculate the number of rolls for each number 2-12, and show that in a histogram.
Any suggestions? THANK YOU for any help!

This looks like homework, however I would assume you want to do something like:
++frequency[i] = (1 + rand() % 6);
b/c with what you typed, your not storing anything within the array.
