edit->SetPasswordChar(0x25CF); // --> stack fault

I'm not sure how Windows CE treats char. But try using some simple char like '*' first.

has no effect - SetPasswordChar requieres a TCHAR as parameter

Windows CE only supports Unicode.
So all string MUST be L"" and all characters are 2 bytes.

«_Superman_»

i know...

0x25CF are 2 bytes, or not?

ans strings with L"" or _T("") or TEXT("")...
there is a single Character as parameter required in TCHAR-Format...

the app works in emulator, it must be devicedependend...
on an other device the app has no problem and works...

thanx

If i don't use SetFont...it works fine...

Since the edit control is just going to show a * anyway, why does it need a different font?

i change the fontsize to fit in the control...
e.g. from size 8 to 15 - and the oher edit controls have size 15
looks not so fine, if the passwordcontrol has only size 8

if i use '*' as default, the access violation occurs if i set a new font.

if the flag ES_PASSWORD or a PassworChar is set and i try to set a new font the access violation is always generated...

i have no idea...

Did you maybe set the WS_CLIPCHILDREN style on the list control? I have seen that resulting in the header not getting drawn in various situations. Anyways, you could try subclassing your list, handling WM_HSCROLL, relaying it to the superclass and then invalidating the header control, maybe it helps, but imho your header should get displayed by default if you do scrolling, so there must be something influencing the workings of the list control.

Any difference between IP_MULTICAST_LOOP and SIO_MULTIPOINT_LOOPBACK?

Hi there.

I just want to get .pdf file related inforamtion like Title, Author, Subject, Keywords, Created, Modified etc.

1. Do we have Windows APIs for the same?
2. Or I need to use Adobe provided APIs. In case Adobe APIs, then can someone please suggest some pointer in regard to Adobe APIs to do the job.

Thanks & Regards

For Modified Date and Time I can use _strtime(timebuf) and _strdate(datebuf) APIs. Any pointers for Title, Author, Subject, Keywords will be helpful...Thanks

The information you desire can easily be obtained by calling StgOpenStorageEx(), and then getting an IPropertyStorage interface.

Windows has no PDF APIs.

Here's a link[^] to the Adobe PDF SDK - you need a license from Adobe to use that.

There are other alternatives - Google for "PDF SDK".

If you were using Mac OS X, you could be using PDFKit[^] - PDF support is built into OS X.

Thanks. Anyway, like we can get file info. using Windows API, Can't we use Windows APIs to get info. for .pdf file. They are also files...I mean if I can get its modified date/time using Windows APIs then there should be some way to get rest of the information. Just want to know about this for knowledge purpose.

As Stuart said there is no native Windows API to read a .pdf file. As it's an Adobe file format and not a Microsoft format why would there be?

Date and time info is common to all files in the file system so there are API ways to read and write it. The data you're looking for is specific to Adobe's pdf format, so you'll need to look elsewhere like the links Stuart gave to find a way to programatically read it.

No, it's part of the compound document interface.
