Tokenize thrice. Once with "\r\n" as the delimiter to count the number of array elements. Allocate two new arrays with that size. Then repeat the previous tokenizing to split one line and then tokenize the got line with "," to get the number and the text. Keep an index counter and fill both the arrays simultaneously.
You must be able to code what I said.

Well, because you have indeed attempted something, I'll help with a very very basic implementation.
void Job()
{
char *data = strdup("1,aaa\r\n2,bbb\r\n3,ccc\r\n4,ddd\r\n");
char *p = data;
int n = 0;
while(*p)
{
if('\r' == *p)
{
n++;
p++;
}
p++;
}
char **text = new char*[n];
int *nums = new int[n];
int i = 0;
char *tok = strtok(data, "\r\n");
while(tok)
{
char *t = tok;
while(*tok)
{
if(',' == *tok)
{
*tok = 0;
nums[i] = atoi(t);
t = tok+1;
}
tok++;
}
text[i] = strdup(t);
i++;
tok = strtok(NULL, "\r\n");
}
for(i = 0; i<n; i++)
free(text[i]);
delete [] text;
delete [] nums;
free(data);
}
It is not recommended to play around with too many pointers. Use std::string and std::vector in place of arrays. And use strtok_s(...) instead of strtok(...) to reduce those loops into simple function calls. I am using VC6 which doesn't have that and hence have written out those loops.

does it not look as simple as tokenizing the strings on ',' and getting the last character of tokenized string to store in one array and the rest of the part in another after removing \r\n. If the last character is not a \n then only you need to add it to the array containing numbers.

can u please send me some sample code .

As others already told you, the answer is tokenize the string alternating "," and "\r\n" as delimiters.
Nobody will give you a sample nor will do the work for you; if you don't know how to tokenize a string, look at strtok, wcstok, _mbstok (CRT)[^]

its nothing like that I hv not tried, but some where I stucked , Here by I m putting my code what I hv done till nw.
char* szStr = "2,aaa\r\n3,bbb\r\n4,ccc\r\n5,ddd\r\n6,eee\r\n" ;
int len = strlen(szStr);
char* tempstrlen = new char[len + 1 ];
char* tempstrst = new char[len + 1 ] ;
char* tempstr1 = NULL ;
char* tempstr2 = NULL ;
int nlang[12] ;
char* szTag[5] ;
memset(tempstrlen,0x00,sizeof(char) * (len + 1)) ;
memcpy(tempstrlen,szStr,sizeof(char) * len);
memset(tempstrst,0x00,sizeof(char) * (len + 1));
memcpy(tempstrst,szStr,sizeof(char) * len) ;
tempstr1 = tempstrlen ;
tempstr1 = strtok(tempstrst,"\r\n");
// nlang[0] = atoi(tempstr1) ;
szTag[0]= tempstr1 ;
int nCount = 0 ;
int nCountChar = 0 ;
while((tempstrst != NULL) && (nCount != 4))
{
tempstr1 = strtok(NULL,"\r\n");
szTag[nCount + 1]= tempstr1 ;
nCount++ ;
}
int i = 0;
char* txt = NULL ;
for(i = 0 ;i < 5 ; i++ );
{
txt = strtok(szTag[i],",");
nlang[0] = atoi(txt) ;
while(szTag!=NULL && i>=0)
{
txt = strtok(szTag[i],",");
nlang[i] = atoi(txt);
i++ ;
}
i++ ;
}
please go through that and tell me where I m going wrong.

Try to work around this snippet:
char *szStr = "2,aaa\r\n3,bbb\r\n4,ccc\r\n5,ddd\r\n6,eee\r\n";
char *token1 = strtok(szStr, ",");
char *token2 = strtok(NULL, "\r\n");
int n = 1;
while (token1 != NULL && token2 != NULL && n < 5)
{
token1 = strtok(NULL, ",");
token2 = strtok(NULL, "\r\n");
n++;
}

wow. Thats ridden with so many flaws. The main one is using tokenizing on a const char*. Did you simply type that out here ?

Now it works properly:
char szStr[] = "2,aaa\r\n3,bbb\r\n4,ccc\r\n5,ddd\r\n6,eee\r\n";
char *token1 = strtok(szStr, ",");
char *token2 = strtok(NULL, "\r\n");
std::vector<int> nums;
std::vector<std::string> strings;
if (token1 != NULL && token2 != NULL)
{
nums.push_back(atoi(token1));
strings.push_back(token2);
}
while (token1 != NULL && token2 != NULL)
{
token1 = strtok(NULL, ",");
token2 = strtok(NULL, "\r\n");
if (token1 != NULL && token2 != NULL)
{
nums.push_back(atoi(token1));
strings.push_back(token2);
}
}

I'm using Microsoft Visual Studio 2005 and I'm new to MFC application. The task I'm given is to create a popup menu (CMenu::CreatePopupMenu) somehow looks like a list control. This occurs to do some limitation of a list control.
Is there a way to do it without using WM_DRAWITEM and WM_MEASUREITEM? Or does anyone knows how to attach a popup menu onto a picture control (CStatic)? or ShowWindow to show the popup menu permanently? Either way is fine with me.
Will be waiting for reply~ TQ!!!
Sincerely,

Can you explain a bit more what you need?
What I understood is that you want to use a popup menu instead than a list control because you want something like a list control with reduced functionalities and custom behaviours; isn't it?
Can't you write a class that inherit from CListCtrl and modifies the standard behaviours?
|

Yes. Just like what u mentioned. What I need to do is to create a popup menu literally looks like list control. The reason why I do so is because I found out that the list control icon attribute as following...
m_list.SetExtendedStyle(LVS_EX_SUBITEMIMAGES | LVS_EX_FULLROWSELECT);
...where when I click on one of the item, I manage to select the whole row but not able to highlight the icon itself. If u have notice, when you put in the above code, there will be an empty white space reserved for the icon to be loaded. My original task is to eliminate that white space (in other words is to make it transparent).
For example, I'm trying to make the list control to be exactly same as the right click button in Adobe PDF reader where i can select whole row with icon (transparent background) and a tick (check mark).
By the way, the icons I obtained is from EnumWindowProc where I get from Window Application (same as ALT + TAB button)

Then what you want is a list control with a customized appearance.
For this, the best is to use a owner-draw list control with the owner-draw property set (i.e. created using the LVS_OWNERDRAWFIXED style); then process the WM_DRAWITEM to give your control the apeearance you want.
Look at these links for some samples:

Thanks for the reply. I'll look into it. I was hoping to find alternative way to solve it without using owner-draw or other drawing method. If that's the case, I shall study on it. Thanks again.

I'm not sure that I fully understand your question, but a popup menu is, by its nature, a transient item. It pops up, the user makes a selection, it disappears. If you want some sort of permanent list on display I think you may need to use a different control. Perhaps you could give some more detail on the problem you are trying to solve.

I am still very confused about your requirements. If you have a popup menu then the selection rectangle will cover the entire width of the item you select; just right click on this page and move your mouse up and down the list.

Sorry for the confusion, I was given task to make a list control with icons (EnumWindowProc from windows' applications) and a tick (check mark) to indicate my item is selected when I double click on it.
However, the drawback of using list control occurs when I highlight the item before double clicking it. This is where my task given, I am suppose to make a full row highlight without white space (especially when there is an icon in the list). The white space is reserved for the icons inserted into it.
Hence, I was trying to use CMenu to obtain desirable results (exp: right click on PDF file to see the popup menu).  Nevertheless, by using popup menu, I am not able to show the popup menu permanently as we can do with list control.
I hope my statements do clear up the confusion made. Thanks for your patient to help me out.
Sincerely,

If you use a normal list control with the LVS_EX_FULLROWSELECT style then you will get the result you are asking for. Take a look at any Windows program (Windows Explorer for example) that has a list view and you will see what I mean.

Thanks for your reply. I have try it out but no different. There is still white space withing that icon area.

I am still not sure what it is you are trying to achieve and why white space is so important.
