I'm hosting MSHTML in an Explorer bar, and a specific Web page is causing a crash in MSHTML. No other page has done that for me. I'm trying to figure out why it's happening, but I can't make sense of the call stack. MSHTML is hosted with a download control which should be preventing dynamic content from being displayed/executed, so it's curious why the call stack appears to be attempting to process some window message. Or maybe not. Any pointers? Thanks!

Here's the call stack I obtained from VS.NET:
> MSHTML.DLL!CElement::BecomeCurrent() + 0x50
MSHTML.DLL!CElement::BubbleBecomeCurrent() + 0x61
MSHTML.DLL!CMarkup::NavigateHere() + 0x47e69
MSHTML.DLL!CTaskLookForBookmark::OnRun() + 0x42
MSHTML.DLL!CTask::TaskmanRunTask() + 0x34
MSHTML.DLL!CTask::TaskmanRun() + 0xb1
MSHTML.DLL!CTask::OnTaskTick() + 0x5
MSHTML.DLL!GWMouseProc() - 0x1f0a99
MSHTML.DLL!GlobalWndProc() + 0xf9
user32.dll!_InternalCallWinProc@20() + 0x1b
user32.dll!_UserCallWinProcCheckWow@32() + 0xb7
user32.dll!_DispatchMessageWorker@8() + 0xd8
user32.dll!_DispatchMessageW@4() + 0xb
ole32.dll!CDllHost::STAWorkerLoop() + 0x69
ole32.dll!CDllHost::WorkerThread() + 0xd6
ole32.dll!DLLHostThreadEntry() + 0x9
ole32.dll!CRpcThread::WorkerLoop() + 0x1e
ole32.dll!CRpcThreadCache::RpcWorkerThreadEntry() + 0x1a
kernel32.dll!_BaseThreadStart@8() + 0x37

I have a similar call stack from WinDbg:

Hi, i´m having some problems to install a lsp on a Windows NT 4 Service Pack 6.
It´s Fail at WSCInstallProvider(...)
The Strange Thing is that LSP is working fine on Windows 2000, and Windows XP.

I Didn´t find any changes (prototype or argument numbers) related with this function.
Somebody here knows what could be happening ?

Thanks,

System tray menu

I have a system tray icon that displays a menu when you right click on it, but it doesn't disappear when you click elsewhere on the screen.

To make it disappear you have to click an item on the menu.

Does anyone know why this is happening?

Thanks

I had exactly the same problem a while ago. Search the microsoft knowledge base for Q135788 to get
the explanation.

    ...Create menu hMenu...

SetForegroundWindow(hWnd); // See Q135788 PRB: Menus for Notification Icons Do Not Work Correctly

BOOL nReturn = TrackPopupMenu (hMenu, TPM_NONOTIFY | TPM_RETURNCMD | TPM_LEFTBUTTON, pt.x, pt.y, 0, hWnd, NULL);
PostMessage(hWnd, WM_NULL, 0, 0);

Localizing a Windows Installer Package

I'm trying to localize a Windows installer package (.msi) built with VS.net 2003. I followed the steps written in MSDN.
However, only the "Preparing to install" dialog is displayed in the localized language, the rest of the installer is still in English. The language/codepage ID's seem to be OK, the localized strings are also in the MSI.

Have anyone ever met this problem? Any tips?

swapping problem

ns9-Mar-04 6:11

9-Mar-04 6:11

I have an algo which takes in an iterator range like Func(I beg, I end).
These are randomaccess iterators so I can do stuff like beg[i] which gives me back the ref to the ith element of the underlying container:

T& t = beg[i].

Now inside the algo I want to swap the contents of say beg[i] and beg[j], and all I have info about is the range. I dont have any info about the type T within my algorithm.

However to do a swap I need a temporary variable to store one of the values :

T& temp = beg[i];
beg[i] = beg[j];
beg[j] = temp;

However, as I said, theres no info on T coming into the algo, so how would I swap the contents using these randomaccess iterators since I very well cant define a 'temp'?
Confused | :confused:

thanks,
ns

T& was your problem. Make it T. But std::swap is better anyways.

std::swap was good.

But see, I couldnt use anything to do with T within my generic algo which has signature Func(I beg, I end), since only the range is coming in, not the type in the container.
Thanks,
ns

I see. You must make your algorithm a template function to do this.

Is there method to set DeviceCaps so as if system font changed?

Is there method to set DeviceCaps so as if system font changed?

System font changed and all sized in a dialog too,
but I want that all sized remained same,

is it possible to make by some CDC tune or
font Dialog or else change?

(Remaining system font changed)

thanks.

Maybe it's the language barrier, but what exactly are you asking?

Are you wanting to change the system font?

Are you wanting to know when the system font changes?

Something else?

Sorry for not good language,
(around people was preventing me from better check, sorry,
but I will try to write better nonetheless)

System font changed by yser,

but in my CDialog I want font at screen remains not changed,
the main purpose- control's distances remains not changed,
due to they are rendered according to system font.

For this purpose is need to chnge something at CDialog.
Is it only font?
It is roughly changed - not with decimal digits as system font.
So precise in control rendering is lost.

Or I can change spme DC properties?

Are you wanting a dialog's font to remain unchanged no matter what the system font is changed to? I'm sure this is possible, but it totally goes against good design. The user should be able to configure their system (e.g., fonts, colors, sizes, sounds) and all applications should reflect those changes.

Bitmaps are pixel- based,
and if you want to combine Dialog controls with pixel based controls you
get either big work with it to resize pixels,
to make picture seems correct - that's main benefit.

or just by compensating font,
you can get same without big work.

Design- is agreement between concrete user and developer as sailer of system,
and additional tune is good but cost, but may fully not in need.

Or user especially want to have system untuned, due to they pay for it.
