It is not clear what you want to do but i will assume you want to force the desktop to be redrawn, try this:
::InvalidateRect(NULL, NULL, TRUE);
and see if it produces what you wish or not.

What exactly do you mean by "refresh"?

"refresh" just is a action for repainting the desktop, you can do the action by pressing right mouse button on the desktop and clicking the refurbish item on the pop-up menu

So, i used spy++ too, turning off the logging of lstview messages and here is what i found:
after you select the "Refresh" item from the popup menu, the desktop(which seems to be a "SysListView32", or have one on it) seems to receive a (WM_USER+3152) message, with wParam set to zero and lParam set to 0xFF000000, after this, it seems to start refreshing itself, turns off its own redrawing (WM_SETREDRAW), removes all the items in it, meaning the icons (LVM_DELETEALLITEMS), inserts them again (LVM_INSERTITEM), then turns back on redrawing and redraws itself (WM_ERASEBACKGROUND, WM_PAINT). I have no idea what you want to do and why you need this, or if i actually posted what you require. This is on Windows XP Pro SP3. So does this help anything?

Hi,
Is it possible to export a string to CSV when the string contains a comma, and then without losing the format of the string?
I dont want to replace the comma with a different character because I am exporting the string so it can be auditted by a different person.
If so, could you point me to where it explains to do it.
Thanks
Tony

Outwardly (I've not tested) yes, just surround with double quotes the fields containing commas: [^].

I want to get the string selected in a list control(not in list box) and save it in another variable. Smebody plz help.
Thanks in advance.

Use ListView_GetSelectionMark [^] to retrieve the selected item index and then use such index in ListView_GetItemText [^] call.

I have created a win32 application, in which a window is created say mywindow1 and after that I am creating other window in the same application say mywindow2. Based upon some condition Mywindow2 is created, if the condition is not satisfied mywindow2 will not be created that is fine (no problem with this scenario). But when Mywindow2 is created it is not a child of mywindow1. While creating the mywindow2 I am using findwindow(null, “mywindow1”) method to get the handle and then using hidewindow(mywindow1hndl) mywindow1 is hided.
Now my question is, finding a window handle using window name and hiding the window is a good idea or not in the real time application. Will this create a problem in the future? If not what is the best way to do it?
Thanks,
Nandu

How are you creating your window? Do you use the WS_CHILD value while creating it?
You need to google first, if you have "It's urgent please" mentioned in your question.

As I mentioned mywindow2 is not a child of mywindow1. mywindow2 is total a separate window.

Since you know when first window is alive or not (after all you create, destroy or hide the window...) why don't you set a global flag and use it?

What will happen or what will be the problem if I hide and create window as mentioned above. Why we should go that way and problem it will cause and why is it a bad idea?

Using FindWindow() could work or it could possibly result in a failure or a deadlock. What FindWindow() does internally is call EnumWindows(), and for each top-level window handle found, it sends a WM_GETTEXT message to the window handle. Now if the thread that owns the handle is blocked (e.g., on a Semaphore, a Mutex, an Event, an I/O operation, or some other manner), the SendMessage() call will block until that thread is freed up. Worst case, this may never happen so FindWindow() will block forever.

I want to draw an image on wizard(CpropertySheet - wizard mode)'s top, it has Wizard97 style and I hide the header, so that this image can be seen on every page of that wizard.
I have drawn the image in OnPint() handler and return TRUE from OnEraseBkgnd() handler of CPropertySheet derived class. From every page, I return FALSE from OnEraseBkgnd() handler.
But this is not working as I want to work.
BOOL MyWizardSheet::OnInitDialog()
{
if(NULL == m_hBitmap)
{
m_hBitmap = (HBITMAP)LoadImage( NULL,
szManufactureLogoName.GetBuffer(),
IMAGE_BITMAP,
0,
0,
LR_LOADFROMFILE );
szManufactureLogoName.ReleaseBuffer();
}
return CPropertySheet::OnInitDialog();
}
void MyWizardSheet::OnPaint()
{
CPaintDC dc(this);
CBitmap cbitmap;
BITMAP pbm;
if(NULL != m_hBitmap)
{
cbitmap.Attach(m_hBitmap);
cbitmap.GetBitmap(&pbm);
CDC dcMemory;
dcMemory.CreateCompatibleDC (&dc);
CBitmap* pOldBitmap = dcMemory.SelectObject (&cbitmap);
CRect rect;
GetClientRect (&rect);
dc.StretchBlt(0, 0, rect.Width(),pbm.bmHeight,
&dcMemory,
0, 0, pbm.bmWidth, pbm.bmHeight, SRCCOPY);
dcMemory.SelectObject (pOldBitmap);
}
}

You may try moving your drawing code to CPropertyPage derived classes.

Morning,everybody !
why doesn't this code use option "/O2" in VC/VS2003 compiler, it can print "Error".
but if you use "/Od" , it doesn't print Error. why ???
#include <stdio.h>
int main()
{
static const int T[1] = {0};
int n = 0;
for(int i = 536000000; i < 536000004; ++i)
{
if(i < 0)
{
printf("Error is %d\t%x\n",i,i);
break;
}
if(i >= 0 && i < 1)
n += T[i];
}
printf("end\n");
return n;
}
Thanks for your reply !
Best Reguards !

Appears to be a compiler bug.
It disassembles to:
; 12 :
; 13 : for(int i = 536000000; i < 536000004; ++i)
00003 b9 00 b6 f2 1f mov ecx, 536000000 ; 1ff2b600H
00008 b8 00 d8 ca 7f mov eax, OFFSET FLAT:_?T@?1??main@@9@4QBHB+2144000000
$L585:
; 14 : {
; 15 : if(i < 0)
0000d 3d 00 00 00 00 cmp eax, OFFSET FLAT:_?T@?1??main@@9@4QBHB
00012 7c 25 jl SHORT $L599

Because /Od suppresses code movement, the compiler likely removed the if() block since it detects i is never less than 0.

This appears to be fixed in newer compilers.
