your code have some problem..

use ILC_COLOR32 along with ILC_MASK
hSmall = ImageList_Create(GetSystemMetrics(SM_CXSMICON),GetSystemMetrics(SM_CYSMICON), ILC_COLOR32|ILC_MASK, 1, 1);

Should not call DestroyIcon for a resource icon.
Also show me how you called the ListView_InsertItem().

I am using listview two times.
1) first when i read all the xml content and display it in the listview.(on WM_INITDIALOG)
for that all columns draw first time in this call back(i will manage it if first time image add
by the (2)). (this is when application open firstime)
(after opened application- new dialog contain combo and new call back - and listview HANDLE is global )
2) when I add any new item in the list view through open dialog.(when COMBO event selchange)
then the new values(files) add diretly in this when i used open dialog.(want to add image/icon here ). when dialog close.the listview saved and display by (1).(this is when running application).
//same for all sub items
<br />
LvItem.iItem=i; <br />
LvItem.iSubItem=0;
LvItem.pszText=(LPWSTR)w_UploadedFile;<br />
SendMessage(hList,LVM_INSERTITEM,0,(LPARAM)&LvItem);

why didnt you set the mask member of the LVITEM? Also you havent set the iImage member of the structure LVITEM. If you didnt set this values, image will not appear.
LvItem.iItem=i;
LvItem.iImage = 0;// 0th image in the image list
LvItem.mask = LVIF_TEXT|LVIF_IMAGE
LvItem.iSubItem=0; //using loop for sub item
LvItem.pszText=(LPWSTR)w_UploadedFile;
SendMessage(hList,LVM_INSERTITEM,0,(LPARAM)&LvItem);//please refer LVM_SETITEM for sub item

Hi all,
I need to know the status of the physical memory.
Total physical memory of my machine is 512 MB.
But when i use GlobalMemoryStatusEx API, it shows the size as 503 MB.
Why it happens so?
MSDN says that the values retrieved by this function is volatile.
How can know the exact physical memory size?
Any help would be appreciated.
Thanks.

Thanks David.
But it shows 518MB now..But the actual memory is only 512 MB.
What could be the problem..

Hi,
I am writing a code to execute a method of a WMI class. Please find a piece of my code below :
CString wmi_method = WMI_METHOD_GETINSTID;
BSTR wmi_method_bstr = _bstr_t(wmi_method);
IWbemClassObject* l_pClass = NULL;
HRESULT (l_hRes);
l_hRes = m_wmiService->GetObject(L"Win32_WindowsProductActivation", 0, NULL,&l_pClass, NULL); //WMI Call
if (FAILED (l_hRes))
return 0;
IWbemClassObject* l_pInParamsDefinition = NULL; //input parameter definition
IWbemClassObject* l_pOutParams= NULL;
l_hRes = l_pClass->GetMethod(L"GetInstallationID", 0, &l_pInParamsDefinition, &l_pOutParams);
if (FAILED (l_hRes))
{
return 0;
}
IWbemClassObject* l_pClassInstance = NULL;
l_hRes = l_pInParamsDefinition->SpawnInstance(0, &l_pClassInstance);
if (FAILED (l_hRes))
{
l_pClass->Release();
l_pInParamsDefinition->Release();
l_pClassInstance->Release();
return 0;
}
This code is failing because l_pInParamsDefinition value after GetMethod is called is null.
hence it cannot do 'spawnInstalnce' .
Can anyone please let me know what could be wrong.
Thanks,
Manasi

i got the same problem, i found l_pInParamsDefinition is null but l_pOutParams is not null, you can use l_pOutParams to spawnInstance

Yes.

Hi.
I am having a problem with the translation of SEH exceptions into c++ exceptions using visual studio 2005. In the release version it doesn't work, if I disable the optimization (/Od) it works!
Had anybody experience this problem? I really would like a solution or workaround to this.
Thanks.
What follows is a simple demo program:
// set_se_translator.cpp
// compile with: /clr /EHa
#include
#include
#include
using namespace std;
#using
using namespace System;
#define MYEXCEPTION_CODE 0xe0000101
class CMyException
{
public:
unsigned int m_ErrorCode;
EXCEPTION_POINTERS* m_pExp;
CMyException() : m_ErrorCode(0), m_pExp(NULL) {}
CMyException(unsigned int i, EXCEPTION_POINTERS* pExp)
: m_ErrorCode(i), m_pExp(pExp) { }
CMyException(CMyException& c)
: m_ErrorCode(c.m_ErrorCode), m_pExp(c.m_pExp) { }
friend ostream& operator<<(ostream& out, const CMyException& inst)
{
return out << "CMyException[\n" << "Error Code: " << inst.m_ErrorCode << "]";
}
};
void my_trans_func(unsigned int u, PEXCEPTION_POINTERS pExp)
{
cout << "In my_trans_func.\n";
throw CMyException( u, pExp );
}
#pragma managed
void managed_func(void)
{
printf("managed_func\n");
try
{
//RaiseException(MYEXCEPTION_CODE, 0, 0, 0);
int i = 0;
i = 1/i;
}
catch(CMyException x)
{
// This is not printed, ok: it is managed code
printf("managed_func: Caught an SEH exception with exception code: %x\n",
x.m_ErrorCode);
}
catch(...)
{
// This messaeg is printed
printf("managed_func: This is invoked since _set_se_translator is not supported when /clr is used\n");
}
}
#pragma unmanaged
void unmanaged_func(void)
{
printf("unmanaged_func\n");
try
{
//RaiseException(MYEXCEPTION_CODE, 0, 0, 0);
int i = 0;
i = 1/i;
}
catch(CMyException x)
{
// This is not printed!!!
printf("unmanaged_func: Caught an SEH exception with exception code: %x\n",
x.m_ErrorCode);
}
catch(...) {
// Neither do this!!!
printf("unmanaged_func: ugh\n");
}
}
int main(int argc, char** argv)
{
_set_se_translator(my_trans_func);
// It does not matter whether the translator function
// is registered in managed or unmanaged code
managed_func();
unmanaged_func();
return 0;

}No calls to Sleep() are necessary. CRLF should both be sent, not just LF. The initial call to recv() is not necessary. After the subject, an extra CRLF pair is required. The five variables of MailIt() should be made constant so that they are not accidently messed with.

Is there a way to force an app to paint a window, and to Stall any further code from processing until painting is completed. Even CWnd::RedrawWindow() which appears to fit the bill according to the documentation, sometimes returns before painting is completed.

Check out CWnd::Invalidate()/::InvalidateRect() and CWnd::UpdateWindow(). Used in combination
they force an immediate WM_PAINT message.

Nope, it appears to POST these messages, and the functions return before the painting is completed.

I respectfully disagree 
I use this combination all the time and it paints instantly (as documented):
Invalidate(TRUE/FALSE);
UpdateWindow();
That's for entire window - you can, of course, invalidate a portion of a Window using a rect or
region.

Hi Mark,
Thanks for your Interest. This is an issue that has caused bother for the last five years. I am trying to handle it head on now, without re-designing five years of code.
As an example, I have a Dialog Based App, which has a Maximised Window displaying a BMP as background. Message Handlers for the Dlg are typically as follows:-
void MyDialog::OnButton(){
.
.
.
COtherDlg Dlg;
ShowWindow(SW_HIDE);
LRESULT lRes=Dlg.DoModal();
ShowWindow(SW_SHOWNORMAL);
if(lRes==....
.
.
.
}
BOOL COtherDlg::OnInitDialog(){
CDialog::OnInitDialog();
DoSomethingVerryLengthy()
.
.
.
return TRUE;
}
The ShowWindow(SW_HIDE) causes the Entire App to disapear off the horizon, showing an Excell Worksheet, or whatever else is running one level lower on the Windows Stack. No Amount of UpdateWindow() InvalidateXXX() etc has got around this, I Keep seeing Excell for the Duration of
DoSomethingVerryLengthy().
Ofcourse, One solution is running things on Workerthreads, use Progress boxes, etc. Can be done, but I feel the overhead of this is unjustified if I can just find a way for the app to keep on filling the screen without showing Excell.
By the way, Tried your suggestion, by macroing in as follows:-
#define ShowWindow(X) ShowWindow(X);PaintMainWnd(X)
void PaintMainWnd(int SwType){
if(SwType!=SW_HIDE)return;
CWnd* pWnd=AfxGetMainWnd();
if(pWnd){
pWnd->InvalidateRect(NULL);
pWnd->UpdateWindow();
}
}
Still Seeing Excell, or in this case, the IDE
// By the way, Modified 1st because  seems to give a smiley face
//
// By the way, Modified 2nd to Re-assure that AfxGetMainWnd()
// Actually returns a Pointer to the Background Window.
// It's Paint Method is actually Called!
// in practice the screen is not actually painted.
// The thread appears to get blocked before the physical
// painting takes place. That's why I asked for a way
// to ensure that all physical painting takes place
// before I use the thread for 'DoSomethingVerryLengthy()'
Regards

Check out GetQueueStatus(QS_PAINT)
while (GetQueueStatus(QS_PAINT))
{
AfxGetApp()->PumpMessage();
}
You may be right
I may be crazy

Hi PJ
Just Tried this,
No Avail.
The Problem appears to be in the Kernal, it appears to receive the Paint messages, but only actually paint the screen in it's own good time.

Of course it does. This is what you wanted, right? If you hide the main window then all the
children get hidden too.
DoSomethingVerryLengthy() is in OnInitDialog()?
If so, that won't work well...there's still a bunch of messages that need to be processed before
the window displays - a few WM_SIZEs, etc. then finally a WM_PAINT. If you want the window
comletely initialized and displayed BEFORE DoSomethingVerryLengthy() then maybe post a message to
yourself from OnInitDialog() and in response to that message then DoSomethingVerryLengthy().
No extra threads should be necessary here, a least for the UI - this isn't even real-time screen
updating - just simple window updates.
Putting DoSomethingVerryLengthy() on a separate thread is an option tough.
Remember that if DoSomethingVerryLengthy() is running on COtherDlg's UI thread then you need
to pump messages periodically if you expect the dialog to stay responsive.
Hope that made sense I'm still not caffeinated this morning!

Hi Mark,
Thanks, Also see my other reply.
That's the Nub of the problem, I am calling ShowWindow(SW_HIDE) from a Child Window, NOT the Main Window The Main Window was separately created on the heap, and just displays a bitmap to act as background.
What I want to keep displayed is the Background Bitmap Window, which appears to get clobbered for no good reason. The Question is, to stop it getting clobbered, or, to repaint it before any shenanigans in OnInitDialog();
DoSomethingVerryLengthy() is in OnInitDialog()?
It is fully acceptable and desirable that the Dialog being initialised is not displayed untill OnInitDialog() terminates. (have NO Usefull data to display untill DoSomethingVerryLengthy() completes).
I am NOT worried about displaying this one until much later, i.e. After DoSomethingVerryLengthy() has completed.
The Problem is the Disappearance of the Background window.
Thanks for your comments sofar, they have been helpfull.
regards,
LateNightsInNewry

Thanks to your extended description of what you have going on I think this post is outdated
(see my other reply minutes ago).
There's still a concern if DoSomethingVerryLengthy() doesn't do anything UI related. If that's
the case then there's definitely a problem having it in OnInitDialog(). Actually, until you
return from OnInitDialog() the UI isn't going to refresh.
Where does DoSomethingVerryLengthy() fit in to your latest detailed post (which window class)?
Mark

Also...
The point I'm trying to make is that OnInitDialog is just called in response to one of the many
messages that get sent to a window during creation before the window is displayed. Trying to
do any UI updating in there won't work well Therefore, it works best to let the window be
entirely created and displayed before doing something else, especially something lengthy.
An alternative to posting yourself a message in OnInitDialog() is to start the
DoSomethingVerryLengthy() externally (via a method call) from the window that created the dialog.
I mean something like:
pOtherDlg = new COtherDlg(...);
pOtherDlg->Create(...);
//** Optional if pOtherDlg not created with WS_VISIBLE style **
pOtherDlg->ShowWindow(SW_SHOW);
pOtherDlg->UpdateWindow();
//** End Optional if pOtherDlg not created with WS_VISIBLE style **
pOtherDlg->DoSomethingVerryLengthy();
Come on, caffeine
Cheers!
