getting internet explorer address

24-Oct-01 8:23

CDialogBar uses command UI update mechanism for buttons. You should add ON_COMMAND handler in the frame class - this will solve the problem of disabled button and provide a place for code which will be executed when user pushes the button. If you want to conditionally enable/disable the button, add ON_UPDATE_COMMAND_UI as well.

Does anyone know how to get the address that internet explorer is browsing? And how to do this for multiple instances of IE? This is for a little program to monitor Web contents that is viewed on a LAN (to keep an eye on naughty students Wink | ;)

)

Thanks

Use the BeforeNavigate2 event from IE and write a Browser Helper Object DLL, this will work with every instance of IE.

Use google.com to search for "BeforeNavigate2" and "BHO", you'll find enough resources

Counting lines in textfile

24-Oct-01 7:29

Hi
I want to count the number of lines in a textfile.
I know how to open and read from a file, but how can I read exactly line after line?

Are you using FILE*, MFC's CFile, standard C++ iostreams, or pure Win32 CreateFile?

I'm familar with FILE* and CFile.

If possible, I'd like to use pure Win32 without MFC

You'll have to look for line breaks yourself - Win32 API doesn't differentiate between 'binary' and 'text' files. Call ReadFile in the loop until EOF and search for \n in the input buffer.

Ok thanks I will try Smile | :)

Is there an easier way with MFC?

fopen and CFile::Open Differences

Yes, there is. Use CStdioFile, pass CFile::typeText when opening the file, and call CStdioFile::ReadString until you reach EOF. Each ReadString reads one line of text.

Thanks! :)

Works fine Smile | :)

Tomorrow I'll try the Non-MFC way Smile | :)

I use the following in a number of apps

if ( !(m_pLogFile = fopen(lpFileName, "a+")) )

which will create a file if it doesn't exist, or if it does, append to the end of the file. Very handy for log files and such. In another app, I'm using a CFile object

CFileException      exFileError;
if ( !m_fileExtract.Open( m_strQualifiedPathAndFilename, CFile::modeCreate|CFile::modeNoTruncate|CFile::modeWrite|CFile::shareExclusive, &exFileError ) )

and the no matter what various combinations of options I specify, I can not get it to append to an existing file. Is this something that is missing from the CFile class, and if it is, I welcome suggestions for how to do appending to an existing file.

Thanks.

Maybe you should move the file pointer to the end of file? modeNoTruncate combined with modeCreate should open the file if it already exist without erasing its contents. Try calling SeekToEnd after Open.

Tomasz, you are always on the ball!

I'm just looking into various positioning methods of the CFile class and expect that is what I'll try. I was expecting CFile to have an 'append' option for the Open method and since there isn't, I'll have to do it myself.

Thanks for the help, again Smile | :)

TOOL TIPS

24-Oct-01 6:31

i am having a problem with tool tips displaying slowly.
At first i thought they were not working. but i found i left my mouse over the control for about a second the tip came up. After that all the tooltips for the objects beside them, as long as i did not lose focus of any, came up fast.

I have an onnotify message
ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNotify)
and it does not init for about 1 sec after i move to the control. Also if i keep moving the mouse over the control it will not init. I have to stop

I hope this makes sense.

thank you:
confused:

TTN_NEEDTEXT is sent just before tooltips shows itself. Did you try to change the activation time with CToolTipCtrl::SetDelayTime?

Tomasz Sowinski -- http://www.shooltz.com

24-Oct-01 7:05

i have declared
CToolTipCtrl m_tooltip;

then call
m_tooltip.SetDelayTime(0);

and get the following compile error
'CToolTipCtrl::SetDelayTime' : illegal call of non-static member function

i know i am probably doing something incorrectly or in the wrong order
but i am not sure what

Tomasz Sowinski24-Oct-01 7:18

24-Oct-01 7:18

Funny. It should compile without much problems. Try this:

m_tooltip.SetDelayTime(500, TTDT_INITIAL);
m_tooltip.SetDelayTime(250, TTDT_RESHOW);
