How to change the index of Header Item?

Hi,
I want to change the index of header Item on drag drop. If header item 0 drag drop to next header column(After HeaderCol 1) then change the index of Header item 0 to 1. & Header Item 1 index to 0. I am using GetItem() & SetItem() but that's not working. How to do this?

Please make the correction in the code:-

On DragDropFunc()
{
HDITEM pHeaderItemCurrent,pHeaderItemNew;
TCHAR lpBuffer[256];
TCHAR lpBuffer1[256];

pHeaderItemCurrent.pszText = lpBuffer;
pHeaderItemCurrent.cchTextMax = 256;
pHeaderItemNew.pszText = lpBuffer1;
pHeaderItemNew.cchTextMax = 256;

m_HeaderCtrl.GetItem(0,&pHeaderItemCurrent);
m_HeaderCtrl.GetItem(1,&pHeaderItemNew);

m_HeaderCtrl.SetItem(0, &pHeaderItemNew);
m_HeaderCtrl.SetItem(1, &pHeaderItemCurrent);

}

Thanks:-
Mike

Are you in search of this ?
m_mylistcontrol.SetExtendedStyle(LVS_EX_HEADERDRAGDROP);

You need to google first, if you have "It's urgent please" mentioned in your question.

NO. I have already added the HDS_DRAGDROP while creating the header control.

What I need is to change the header Id which we specify while insertion. i.e
m_header.InsertItem(columnId, &hditem);//columnId =1;

Now How Can assign the some different hditem to columnId = 1;
I try with SetItem() as in code but its not working......

Any suggestion.

Just one quick question. Why do you want to change the index of the item?

You need to google first, if you have "It's urgent please" mentioned in your question.

Yes. I need to change the index of item. The new index will be postion of column after drag drop.

Sample code which caculates HCF/LCM of two or more numbers? [modified]

Hai!
Can you please give me a sample code which calculates HCF and LCM of two or more numbers without using inbuilt functions to calculate HCF & LCM.

If there are more than one methods to calculate HCF/LCM just tell the logic and if possible provide sample code for the best logic.

Thankyou!

The logic is easy to understand. I hope this help you.

Using GetSystemTime in WM_KEYDOWN

EvScott15-Feb-09 16:50

15-Feb-09 16:50

I must be doing something really silly but I'm trying to get the time information when a key is hit down then released (WM_KEYUP). I'm writing a win32 application (doesn't anyone write these anymore?), but when I hit the key, I get a blank messagebox or squares. What am I doing wrong. Any good advice might win you a keg of cool beer or at least, a thanks.

case WM_KEYDOWN:
{
SYSTEMTIME st;
GetSystemTime(&st);
MessageBox(NULL,(LPCWSTR)L"Time is "+ st.wMilliseconds,(LPCWSTR)L"Keystroke Analysis",MB_OK);
}
break; //etc

You cannot add a WORD type to a constant string.
Use the Format method of the CString class to generate the Text for the MessageBox.

Yes.

case WM_KEYDOWN:
{
  
  SYSTEMTIME st;
  GetSystemTime(&st);
  const int BUFSIZE = 0x100;
  TCHAR msg[BUFSIZE];
  HRESULT hr = StringCbPrintf(msg, sizeof(TCHAR) * BUFSIZE, _T("Time is %d"), st.wMilliseconds);

  if (SUCCEEDED(hr)) MessageBox(NULL, msg, _T("Keystroke Analysis"),MB_OK);
}
break;

Thanks,CPallini.I still get the same values when I include your example. However, when I run in debug mode and examine the values, I can see the SYSTEMTIME.wMilliSeconds. Just don't seem able to access it in a messagebox.

I made a test, my code works on my system.
Could you please post your updated code? Are you doing a UNICODE build?
Smile | :)

EvScott16-Feb-09 1:48

Thanks CPallini - Just don't seem to get a sensible output. I've omitted your code for reasons of clarity.

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
SYSTEMTIME st;
PAINTSTRUCT ps;
switch (message)
{
case WM_PAINT:
{
HDC hdc = BeginPaint(hWnd,&ps);
EndPaint(hWnd,&ps);
}
return(0);
break;
case WM_KEYDOWN:
{
SYSTEMTIME st;
GetSystemTime(&st);
//get duration in milliseconds
}
break;
case WM_TIMER:
{

}
break;
case WM_KEYUP:
{
SYSTEMTIME st;
GetSystemTime(&st);
//get duration in milliseconds
}
break;
case WM_DESTROY: // onload from memory
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
return 0;
}

Are you doing a UNICODE build?
What is msg value at runtime, after the StringCbPrintf call (use the debugger to see)?

EvScott16-Feb-09 2:11

16-Feb-09 2:11

Thank you so much CPallini for you contribution. I made a small change to your original code by changing _T to L"" and it worked.
Below is your code that I made small changes to.

HRESULT hr = StringCbPrintf(msg, sizeof(TCHAR) * BUFSIZE, L"Time is %d", st.wMilliseconds);

So I suppose all that's left is to ship that crate of cool beer to ya as promised in my original post. Laugh | :laugh:
