No, but you could: 1) iterate through each and add to a common structure, or 2) change the query to include the other record sets.

Hello,
I'm working on an MFC application. For reasons I cannot fathom, there seems to be a problem with inconsistent display of the icons of an icon style CListCtrl between versions of Windows (XP and Vista). On Vista, one of the icons (Debtor statement) is omitted. This only occurs sometimes. When it actually occurs varies from build to build of the application, where changes between builds ought to have no bearing on this at all.
Why might this be? How can the problem be fixed? Here is the relevant code:
CMyReportView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
ModifyStyleEx(WS_EX_CLIENTEDGE, 0, SWP_FRAMECHANGED);
ReportsCtrl.ModifyStyle(0, LVS_AUTOARRANGE);
// Send an ID_RELOAD rather than calling UpdateStateData() directly - this is
// a hack to work around the problem of no icons being displayed initially
// in release build
SendMessage(ID_RELOAD );
}
CMyReportView::UpdateData()
{
CBitmap sales_bitmap,
daily_reconciliation_bitmap,
debtor_statement_bitmap,
debtor_invoice_bitmap,
voided_items_bitmap,
suspended_sales_bitmap,
stock_count_rep_bitmap,

I seem to have isolated the problem somewhat (It still erratically tends to swing between omitting and not omitting the icon between builds, I guess).
By commenting out:
ReportsCtrl.ModifyStyle(0, LVS_AUTOARRANGE);
I can make the problem disappear (although I have a new problem, which is that the icons are displayed as one big column). Commenting out anything else of note doesn't have the effect of suppressing the problem, so I guess that's progress.
Regards,
Sternocera

Hi Sternocera,
Where are you setting the column width?
|
|
|
|
|
Hi Randor,
I'm not - it isn't a report style CListCtrl, it's an icon style CListCtrl. I understand that column width isn't set with an icon style CListCtrl.

Sternocera

Have you entertained the possibility of a bad/corrupt/outdated icon cache? I've had it happen once with an older version of Windows, so it's probably not a common problem.

That seems like a reasonable explanation. I've found that moving the initialisation of the icons into OnIntialUpdate seems to fix the problem, but I'm not overly confident that it hasn't just temporarily concealed the problem.
I'll delete the cache to be sure.

Where is imgl declared? Is its lifetime longer than the lifetime of the list control?
It's a good idea to always zero-init structs, like LVITEM, so that you aren't accidentally sending garbage data in the members that you don't explicitly set.

Hi Mike,
Yes, imgl is declared in the same class definition as the CListCtrl. I have now zero initialised the LVITEM structs. Thanks for your help.
Regards,
Sternocera

|

There is a method that allows adjustment of the icon width: SetIconSpacing() You might try playing around with that.
|
|
|
|
|
I haven't had a re-occurrence since I simply initialised my structs, but thanks for pointing that out.

Hi,
I am working on an application, which calls a WPF page in MFC exe and loads it too, but the backgound for the WPF is coming black.
here is code snippet
Declaration
using namespace System;
using namespace System::Windows;
using namespace System::Windows::Controls;
using namespace System::Windows::Media;
ref class Globals
{
public:
static System::Windows::Interop::HwndSource^ gHwndSource;
static WpfApplication1::Window1^ gwcContainer;
};
i have added in oninitdialog,
System::Windows::Interop::HwndSourceParameters^ sourceParams = gcnew System::Windows::Interop::HwndSourceParameters("MyWindowName");
sourceParams->PositionX = 20;
sourceParams->PositionY = 30;
sourceParams->ParentWindow = System::IntPtr(this->GetSafeHwnd());
sourceParams->WindowStyle = WS_VISIBLE | WS_CHILD;
System::Windows::Interop::HwndSource^ source = gcnew System::Windows::Interop::HwndSource(*sourceParams);
source->SizeToContent = System::Windows::SizeToContent::WidthAndHeight;
Globals::gwcContainer = gcnew WpfApplication1::Window1();
FrameworkElement^ myPage = Globals::gwcContainer;
source->RootVisual = myPage;
I dont want the black color around.
Any help is highly appriciated.
Thanks&Regards,

If you want to use ping from your application, have a look at boost::asio. Boost have a ping example program that you may be able to adopt. Note that your application requires administrative privileges on Vista to create ICMP packets.

How to plug/unplug USB serial port problematically?
I am facing some strange issue with my USB serial port.
I want to unplug and plug the USB Serial port Programitically, as i need to refresh the connection between system and hardware connected.Kindly help.......
Thank in advance for the great programmers

You cannot do that from user mode. You must ask the driver for that functionality if it supports it at all, which I doubt when it comes to serial port drivers for USB.
pallaka wrote: I am facing some strange issue with my USB serial port.
Perhaps you can elaborate on what the "strange issue" is all about.
It's quite possible that there is another solution than resetting the port/device.
What have you done so far and what problems are you facing that you want to solve by resetting the port?

There's a very easy way to check that: put a breakpoint in the function and start your debugger. Once the breakpoint is hit, take a look at the callstack.
