you have to pass the address of the int variable to sscanf, for instance:
int i;
sscanf("1F","%X", &i);
sets i=31;.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Dear all
I have one visual C++ 6.00 MFC dll project.
It contains both C and C++ files.
Every time I open the project and make it clean and ther rebuild all it,
following errors occures.
Linking...
mfcs42d.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in MSVCRTD.lib(dllmain.obj)
mfcs42d.lib(dllmodul.obj) : warning LNK4006: _DllMain@12 already defined in MSVCRTD.lib(dllmain.obj); second definition ignored
Creating library Debug/ecpdll.lib and object Debug/ecpdll.exp
Debug/ecpdll.dll : fatal error LNK1169: one or more multiply defined symbols found
Error executing link.exe.
Creating browse info file...
ecpdll.dll - 2 error(s), 1 warning(s)
When I delete the C file and the header file of it and then re add them to the project this error removes but this style is not good.
May u please help me.
Regards
Tappe

Hi all,
I would like to know whether it is possible to create a vector with more than one level range. For example, lets say you have two sets of integers and you want to populate a vector, how would one do it?
The code piece below shows four ints with value 100, but what if one wanted two sets of four ints with a value of 100.
vector<int> second (4,100);
Level 0 Level 1
0 0
1 1
2 2
3 4
...
Many thanks in advance
Regards,

Would this be an example of such occurance, if so does the following structure perform the same function, if not how can I change the vector to perform the same function:
struct C
{
string coid;
string actualCoid;
}COID[100];
#include <iostream>
#include <vector>
using namespace std;
main()
{
vector< vector<int> > vI2Matrix(3, vector<int>(2,0));
vI2Matrix[0][0] = 0;
vI2Matrix[0][1] = 1;
vI2Matrix[1][0] = 10;
vI2Matrix[1][1] = 11;
vI2Matrix[2][0] = 20;
vI2Matrix[2][1] = 21;
cout << "Loop by index:" << endl;
int ii, jj;
for(ii=0; ii < 3; ii++)
{
for(jj=0; jj < 2; jj++)
{
cout << vI2Matrix[ii][jj] << endl;
}
}
}
Thanks in advance

If i draw some image, lines, rectangles etc. in OnPain() of dialog box then it takes some time. Suppose i draw image,rectangle on mouse click and release event. I can call repaint from mouse click/release function and it's working fine. But suppose if i want to draw some lines on mouse move function then i need to call repaint from mouse move function and it gives flickering problem. To solve this i plan to draw image, rectangle etc in a memory device context on mouse click/release functions. and for mouse move first i'll draw data from memory device context and then i'll draw line on top of it. But it's not working. Can someone give any example to solve that problem.

Which device context you are using on window mouse message handler and are you using ::ReleaseCapture funtion after releasing mouse.If possible pls give me code to understand your problem.

The code is simple. Just Create a dialog base application. Add a static control on dialog box. Make a class for this static control(derived from CStatic). Now draw in this class. In Onpaint() of this class draw some image,rectangle, lines etc. Add all mouse functions in this class. Call Invalidate() from mouse click/release functions. Upto now there is no problem. Now call Invalidate() from mouse move function. You'll see flickering. To solve it take an offscreen buffer. Create image/rectangle in offscreen buffer and draw it on view when Invalidate() is call from mouse click/release function. Otherwise form mouse move function, dont create offscreen buffer, just use previously created offscreen buffer and draw it on view. Then draw lines. I'm not using any capture function like ReleaseCapture(). When i dtied this then i can see only lines. I cant see any image/rectangle. What i want
I want a 2 layers. bottom layer should contains image and rectangle and top layer contains only lines.

are you using CClientDC device context or CPaintDC on OnMouseMove function ? And when i see your code it is clear for me where is the problem?

I'm not using any device context in mousemove. From mouse move i'm calling Invalidate. And in Ontain, i'm using CDC to create memory device context. If your code is working fine then please send here if you can.Or please mail to my id gkv_manoj@yahoo.com

1/ Are you sure you're just invalidating the CMyStatic control? If you're also invalidating the dialog box, then you'll get flickering.
2/ If your code is working, but not with the memory context, then have a look at Keith Rule's CMemDC article. I've used his CMemDC in many places, and it's great.
Just do a search for his name. He didn't write many articles, but it's a golden one.

Yes i'm updating only static control not dialog box.
Thanks i'll search Keith Rule's CMemDC

Yes you get a flickering problem coz when you call OnPaint() or Invalidate()
you are redrawing the whole window. try this
Create your function e.g MyDrawing(int x,int y)
{
CClientDC dc(this);
dc.SetTextColor(RGB(0,0,255));
dc.TextOut(x,y,"my text");
}
in you Mouse Move Handler
{
....
MyDrawing(point.x,point.y);
}
then play around with rectangles

It will work but we need to call Invalidate() also b'se if everytime i draw text at different position then previous text will also visible.

HI
how to convet Cbyte array to Cstring and vice versa

you have to manually code that, i don't think there will be direct method.
you could try memcpy with raw CByteArray object with Char array!, just the suggestion
