sorry in advanced if i posted in wrong forum
I am looking for help how to output a chart into the arrays, all i was given was that i need to put a loop inside of a loop. The chart given is:
0 0 0 0
0 1 2 3
0 2 4 6
0 3 6 9
This is what I have so far:
#include "stdafx.h"<br />
#include "pattern.h"<br />
#include <vector> <br />
#include <fstream><br />
#include <iostream><br />
#include <iomanip><br />
#include <string><br />
<br />
using namespace std;<br />
CWinApp TheApp;<br />
<br />
<br />
<br />
int main()<br />
{<br />
int j;<br />
int i;<br />
int test_score[4][4];<br />
<br />
for(i = 0; i < 4; i++)<br />
{<br />
for(j= 0; j < 4; j++)<br />
{<br />
test_score[i][j] = 0;<br />
cout<< test_score[i][j];<br />
}<br />
<br />
cout<<endl;<br />
}<br />
<br />
<br />
return 0;<br />
}

Hello
re : nested loops
Your loop should look like this:
for(int i = 0 ; i< 4; i++)
{
for(int j = 0 ; j< 4; j++)
{cout << j*i << " " ;
}
cout<< endl;
}
multiplying the outer loop i with the inner j
seems to get the result;
hope this might help

Sorry for such a simple question im sure, but how does a person make sure data types are correct for creating an easy robust program.
code : cout << "Enter number of terms" << endl;<br />
cin >> terms;
I want to make sure terms is an Interger type, can i do that with an if statment?
if (terms = ?(some function call))
or is there another way to code to make sure what is entered is an Integer and not a character or string value?
If at first you don't succeed .... DENY EVERYTHING!

This is standard C++. You're in the C++/CLI forum, try the visual C++ forum.
If terms is an int, I believe it will keep asking until you enter an int value. Or you can accept a std::string and try to parse it yourself and give custom errors. Things like atoi will help here.

Hi,
How can i access filesystem within c++?
Can i use standard C functions? Like chdir, etc?
Thx,
Nuno

If you are looking for native code, please ask this in the Visual C++ forum. Else take a look at the classes in the System.IO namespace.

;PNow i have lots of text files in a folder,i want to combine them into one large file,but the problem is that it is must be order the formation rule.
for instance:(the txt file order)
the first text file list item"1c.txt,2c.txt,.........
the second text file list item"1e.txt,2e.txt,........
now the combine file order must be "1c.txt,1e.txt,2c.txt,2e.txt........."
and so on!
Waiting for ur help!
Thx advance!;P

Hi,
I am new to vc++.net (mfc),i need to know how to add data and column headers to the MSDATAGRID VERSION 6.0 dynamically IN vc++.Net(mfc application), Please someone help me.
I have taken an sdi(mfc application) and added a MS DataGtrid, now i need to add column headers and data to the grid.The code i added to write is
m_DataGrid1.put_Row(1);
m_DataGrid1.put_Col(1);
m_DataGrid1.put_Text("Nit");
the error i got is "rowset not available".
Thanks in advance

Hi,
I have used MS HEIRARCHICAl FLEX GRID
//code to add row by row to a grid
m_FlexGrid.put_Cols(0,6); // number of columns(5)
m_FlexGrid.put_ColHeader(0,1); //setting the header
m_FlexGrid.put_ColWidth(1,0,1300); //col width
m_FlexGrid.put_ColWidth(2,0,1000);
m_FlexGrid.put_ColWidth(3,0,1400);
m_FlexGrid.put_ColWidth(4,0,1500);
m_FlexGrid.put_ColWidth(5,0,1200);
m_FlexGrid.put_ColHeaderCaption(0,1,"Employee Name");//adding //captions to the header
m_FlexGrid.put_ColHeaderCaption(0,2,"Employee ID");
m_FlexGrid.put_ColHeaderCaption(0,3,"Employee Salary");
m_FlexGrid.put_ColHeaderCaption(0,4,"Employee Address");
m_FlexGrid.put_ColHeaderCaption(0,5,"Employee Age");
m_pSet->MoveFirst();
int RowCount=0;
while (!m_pSet->IsEOF())
{
RowCount++;
m_pSet->MoveNext();
}
m_FlexGrid.put_Rows(RowCount+1);
m_pSet->MoveFirst();
int Row=1;
int Col=1;
while (!m_pSet->IsEOF())
{
m_FlexGrid.put_Row(Row);
m_FlexGrid.put_Col(Col++);
m_FlexGrid.put_Text(m_pSet->m_EmpName);
m_FlexGrid.put_Col(Col++);
long var=m_pSet->m_EmpID;
CString str;
str.Format("%d", var);//to convert long to string
m_FlexGrid.put_Text((LPCTSTR) str);
m_FlexGrid.put_Col(Col++);
double var1;
var1=m_pSet->m_EmpSalary;
str.Format("%0.2f",var1);
m_FlexGrid.put_Text((LPCTSTR) str);
m_FlexGrid.put_Col(Col++);
m_FlexGrid.put_Text(m_pSet->m_EmpAddress);
m_FlexGrid.put_Col(Col++);
var=m_pSet->m_EmpAge;
str.Format("%d",var);
m_FlexGrid.put_Text((LPCTSTR)str );
Row++;
Col=1;
m_pSet->MoveNext();
}
I am sending this so that, it may be useful to someone

Well, if you're using C++/CLI, you can do String ^ = "hello world". Your overall question makes me think that you're pretty lost, and probably taking on a project that's too hard for your skill level. So, you may also be confused about what this forum is for. It's for .NET C++, not C++ in general. The visual C++ forum is for that.

Sushant,
We are here to help you solve a specific programming program not to help you write the whole application or, worst yet, write the whole application. If you need some ideas, please search the web with Google with the key words such as "8-puzzle game programming AI".

So, you posted your question on a Visual Studio site, on a Managed C++ message board...
Great,

I'm sorry.
Could you recommend a other forum??
Great,

No problem.
I haven't used Borland in many years but I would start here[^].
I'm not sure what kind of script you're looking for but if you look at the list of message boards
at the top of this page you may find a more appropriate board to post the question on.
Good luck!

hi!
can someone give me a sample code on how to pass 2 different structs to a function with lpvoid as parameter and how to convert back to the structs from lpvoid.
the structs should be received by the lpvoid... how to combine the 2 different structs together? and how to split the lpvoid back to the 2 structs?
the structs are something like
typedef struct
{ int dataStructCount;
DWORD totalSize;
} strHeader;
typedef struct
{ int num;
lptstr str;
} dataStruct;
this will be used for writing and reading data from named pipe.. the header will be used to determine the count of dataStruct send/read.
thanks for any help!

Newbie,
First of all, you are in the wrong forum! This is the C++/CLI or Managed C++ forum. C++/CLI uses the .NET Framework and depends on Garbage Collection (GC) for memory management. It appears you are writing C or possibly C++ code. You should get better assistance int the Visual C++/MFC forum.
However, LPVOID is really a typedef of void*. Thus, LPVOID is a pointer to any type. Unfortunately, once a pointer of a type, in your case strHeader and dataStruct, is casted to a void pointer, LPVOID, its type information is lost. Thus, if you have a function that accepts void pointers, the compiler will not help you with type checking.
void Foo(LPVOID header, LPVOID data)
{
strHeader* theHeader = (strHeader*) header;
dataStruct* theData = (dataStruct*) data;
}
int main()
{
strHeader header;
dataStruct data;
Foo(&strHeader, &dataStruct);
return 0;
}

oooopppss! sorry! i did not notice the message board... i thought i was posting in vc++/mfc forum...
i have reposted the qxn there...
thanks for your reply!
however, for the foo function... i only have 1 LPVOID paramter...
thus the strHeader and dataStruct should be combined together and passed as 1 data to function Foo....

Hi
I'd like to be able to take a set of bitmaps and write them to an avi file without having to use vfw or anything platform specific since it has to be cross-platform
i don't need audio or anything else - just a sequence of images - any ideas?
|
|
|
|
|
|
hi
thanks for the reply but that article show's how to load an avi file as a resource - what i need to do is save a sequence of images as an avi file without using vfw.

|
|
|

If cross-platform is your goal, then using C++/CLI that depends on the .NET Framework would be a bad idea. You are in the wrong forum.
