This is my dilema. I have somethings I'd like to accomplish. The first thing is to get stars(*) to appear when someone puts in thier pin(it's an ATM program). I haven't quite figured it out and I need help understanding it. The next thing would be help with sub-classing. I read a couple of articles on it. NCP(Number, Currency, Percentage) edit controls. The other article I read was on sub-classing. I have an understanding(I don't know for 100% though) of sub-classing for buttons. I've tried doing the same thing for edit controls but I'm having problems understanding it. I'm using Dialog Boxes. Thanx to those to have helped me before and thanx to those who wrote those articles they helped. Thanx for your time and help.

As for your password problem. If you go to your dialogbox and the edit box you just made. Do the following.
Right click on the edit box and go to properties. Then go to style. Put a check mark in password and then whenever you type anything in the edit box you will get ***'s. Hope this helps.

if (user=="Win32newb")

}

I'm looking for an interactive 2d graph control, but the ones in the miscellaneous controls category all seem to be static. By interactive, I mean having the ability to select and move the graphed points with the mouse.

Any ideas?

MSHTML debug help needed

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!CTask::TaskmanRun() + 0xb1

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!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

9-Mar-04 6:51

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.

10-Mar-04 1:14

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.

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?
