Setting size of Multi-dimensional Array dynamically

[DjChris14]

good day to all! i would like to use a multi-dimensional array which size and range are setup dynamically. the array will be placed in the public location of my class because this array will be the one to catch data from another class (having a multi-dimensional array too)..

i try CStringArray but i cant set the additional range for it
Normal Use:
CStringArray cArrRowCol[5];

i want was:
CStringArray cArrRowCol[i]; which " i " varies from what will i give to its value

any idea of it? thanks

Hi

try this


typedef CStringArray* PSTRARRAY;

PSTRARRAY *cArrRowCol;

int x = 5;
cArrRowCol = new PSTRARRAY[x];

for(int i=0;i<5;i++)
{
for(int j=0;j<3;j++)
{
CString str;
str.Format("%d %d",i,j);
cArrRowCol[i]->Add(str);
}
}

hope this could solve your problem

To VladimirV:
i already try your approach the multi-dimensional array unable to catch the data that i have thrown. here is my code snipet:

//header file
typedef CStringArray *PSTRARRAY;

class CReportUI : public CDialog
{
// Construction

public:
PSTRARRAY *cArrRowCol;
CManagerialReport cManage;
CStringArray mv_sArrType;
CString m_sDialogTitle;
CReportUI(CWnd* pParent = NULL); // standard constructor
}

//ccp file
BOOL CReportUI::OnInitDialog()
{
CDialog::OnInitDialog();
SetWindowText(m_sDialogTitle);
SetTypeSelection();
cArrRowCol = new PSTRARRAY[5];
cArrRowCol[0]->Add("hello"); // unable to catch the value
// TODO: Add extra initialization here

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}


To Gabriel Fleseriu: How can i adopt the STL code to my MFC project? i dont have any idea of it...

sorry, there was a mistake, this is working well

typedef CStringArray* PSTRARRAY;

void CCg1Dlg::OnButton1()
{
PSTRARRAY cArrRowCol;
int x = 5;
cArrRowCol = new CStringArray[x];

for(int i=0;i<5;i++)
{
for(int j=0;j<3;j++)
{
CString str;
str.Format("%d %d",i,j);
cArrRowCol[i].Add(str);
}
}

TRACE("%s",cArrRowCol[0].GetAt(0));
TRACE("%s",cArrRowCol[1].GetAt(0));
TRACE("%s",cArrRowCol[2].GetAt(0));
}
