Use a list if you want to delete one or more line.

Thank a lot! Please pardon my weak English! Re: The copy and paste fundtion valikac24-Oct-02 9:48 valikac 24-Oct-02 9:48  What are COPY and PASTE messages? You may want to copy and paste data according to a context menu or when the user presses a certain key.

ATL ActiveX and AxWindow Braulio Dez24-Oct-02 6:01 Braulio Dez 24-Oct-02 6:01  Hi, I need to have an small customized HTML editor ( to use in my main application), it should look like an standalone application, with a toolbar... If I use the HTML control alone, then I won't get the look and feel of a Window application, what I thought was to create a COM object, with a method called StartEditor, this method would show an AxWindow, that inside would have the toolbar and the HTMLControl ( as the ActiveX control hosted in the window), is this a good idea ? Could it be possible to call from my MFC application directly the AxWindow, instead of making a control that shows that window ? Thanks in advance, greetings Braulio Visual C++ 6, er no 7, er 7.1 ? Patje24-Oct-02 5:52 Patje 24-Oct-02 5:52  We are currently using Visual C++ 6.0. Lots of recent developments use lots of templates, and it seems that Visual C++ 6.0 is not very well suited for this (crashes, internal compiler errors, valid C++ does not compile, ...). We would like to upgrade to Visual C++ 7.0, since that seemed to be much better (on our test system), but I already heard rumours about a version 7.1. Anybody knows when that is released ? Or even better, is there a way to make Visual C++ 6.0 work with complex templates ? Maybe via a C++ preprocessor ? Enjoy life, this is not a rehearsal !!! Re: Visual C++ 6, er no 7, er 7.1 ? Joao Vaz24-Oct-02 6:18 Joao Vaz 24-Oct-02 6:18  Partial template specialization(PTS) don't work in VC++ 6 neither in VC++ 7, full and proper namespace lookup also don't work . Patje wrote: but I already heard rumours about a version 7.1. I'm expecting this a long time ago , perphaps in the end of the year before VC++ 8, a much improved C++ std compliant ... VC++ 7 is much better standard compliant and have better support for template support , and the STL(Dinkumware) library is much more improved and standard. For faking PTS, see resources on Joãquin article on STL bi-directional maps here on CP, it's at the front page. See also www.moderncppdesign.com[^] In the page there is a link for the Loki library , a powerfull template library , and it have a link to a port of the library to VC++ 7 where PTS is faked.

I can obtain the names using _TablePtr->GetColumns()->Item[index] function, but then it returns me the names in alphabetical order, how can i get the names in the same order as in the table.. I will be really thankful if someone can help me in this regard. Closing CFrameWnd children Dialogs from Frame Brian Nash24-Oct-02 5:21 Brian Nash 24-Oct-02 5:21  I'm trying to implement a 'inactivity' feature in my MDI/SDI app. Since there are many different modal dialogs that could be up, I'm using windows hooks to set/reset a timer based on keyboard and mouse events. That's all working fine. I'm having a problem killing off any dialogs (who might also have children dialogs) that might be up when the timer kicks off. I'm doing all of this from within my CFrameWnd derived class, but can't simply post WM_CLOSE to the frame, since my frame class has a little 'signon' screen that it reverts to. In my timer handler I've tried SendMessageToDescendants(WM_CLOSE), and I've tried finding children windows with GetWindow(GW_CHILD) and posting WM_CLOSE (even tried WM_DESTROY), but my child windows never seem to care. Actually they never even seem to get the message... If I save off a CWnd* to the currently modal dialog, and then send a WM_CLOSE to that, it'll go away, but it's children hang out. I thought they would go away too. But I'd rather not have to save off that ptr (there are a lot of menu commands that bring up dialogs, dozens and dozens) if there is another way around it.. Anyone have any suggestions? CEdit multiline Mark Donkers24-Oct-02 4:55 Mark Donkers 24-Oct-02 4:55  Ok. I'm almost embarrassed to ask this one, but here goes... I have a dialog box with a CEdit control on it. I'm using it as a logging window, but I can't get it to multiline my text. I'm using a CString member variable to contain the text that is written to it, but when I insert a '\n' or '\r' the CEdit control displays it as a control character inside of moving to the next line. What properties need to be set? The ones that I have checked are: - multiline - horizontal scroll - vertical scroll Am I missing something? Thanks in advance.

I want to get HTTP response header of my HTTP request. I have seen some documents in MSDN, but I think it is too hard to understand. I just want to get all of the header and print it out. Are there some sample codes? Cheers, George Re: What is the easyest way to get HTTP response header?

I use the following codes to get the header of Yahoo, -------- CAmHttpSocket http; TCHAR *ts = http.GetHeaders(_T("http://www.yahoo.com")); CString str = ts; AfxMessageBox(ts); } -------- in the message box, I can only get -------- HTTP/1.1 200 OK -------- I can not get other headers (Content-Length, and cookies etc). Can you tell me how can I get all of the headers? Have a nice weekend, George Re: What is the easyest way to get HTTP response header? Ravi Bhavnani25-Oct-02 1:43 Ravi Bhavnani 25-Oct-02 1:43  The headers received depends on the webserver. Many webservers will only respond with a minimal subset and may also change headers (like the document's last-updated timestamp) to fool you. /ravi Let's put "civil" back in "civilization" http://www.ravib.com ravib@ravib.com Re: What is the easyest way to get HTTP response header?

Todd Smith24-Oct-02 8:48 Todd Smith 24-Oct-02 8:48  What function are you using to send an HTTP request? Some of the IE technologies don't allow you to get the response header.

JohnnyG24-Oct-02 4:49 JohnnyG 24-Oct-02 4:49  I found out how to display colored text in a rich edit control but am having a problem retaining the colored text when doing a ReplaceSel(). Is this normal? Is there a way around it? I mean is there another way of adding lines of text to a rich edit control without doing ReplaceSel? I would like to keep adding text to this rich edit control and am using a method described here where you SetSel(0,-1), GetSelText(), then add my new text to it, and call ReplaceSel() to replace the entire contents of the rich edit control with the old and new text. But, if my old text was colored (only certain portions or certain lines are of different colors), the text is being overwritten to the default color - black text.
