Hi,
I am a C++ programmer and am trying to learn Pearl. Recently I discorved that CGI scripts can also be written in C++ and being as I am much better at that I would like to write my scripts in C++. I am confused on some issues though:
1) Do I compile the program (EXE) upload it to the server and chmod it
2) Do I just upload the code (cpp) and chmod it to 755
3) Is QUERY_STRING analogous to argv or argc
In general you can see that I am clueless about the topic. Any help (especially useful links) would be much appreciated on the topic. Thanks.
P.S. Can C++ do what the Perl scripts all over the internet do (eg. HTML on the fly, reading and processing forms?

The CGI program must be executable, so C++ source won't work. If the server runs some Unix-style OS (you mention chmod 755) , an .EXE compiled in Windows won't work either. You must compile the program on the server. QUERY_STRING is passed as an environment variable, you access it with the getenv() function.
See the CGI primer
The GNU cgicc class library may be useful.

Thanks a lot for the help and the links.

Thanks again for your help, I finally got a basic script running, just some printing to the screen but there is one thing. I can't get it to compile if I use cout, I cant use ofstream and things of the sort. The C equivelents work fine. Does this mean I can forget about c++ on my server and need to stick with c or I am using my includes wrong... Here is what I use to compile:
gcc -o cgitest.cgi cgitest.cpp
and here are the error codes in my telnet client:
/tmp/cccJ3yII.o: In function `main':
/tmp/cccJ3yII.o(.text+0x16): undefined reference to `ofstream::ofstream(int)'/tmp/cccJ3yII.o(.text+0x4b): undefined reference to `ofstream::open(char const *, int, int)'
/tmp/cccJ3yII.o(.text+0x68): undefined reference to `ostream::operator<<(char const *)'
/tmp/cccJ3yII.o(.text+0x7a): undefined reference to `fstreambase::close(void)'
/tmp/cccJ3yII.o(.text+0x104): undefined reference to `ofstream::~ofstream(void)'
/tmp/cccJ3yII.o(.text+0x121): undefined reference to `ofstream::~ofstream(void)'
collect2: ld returned 1 exit status
similar ones for cout... I have included iostream and fstream like so:
<br />
#include iostream.h<br />
#include fstream.h<br />
(with the brackets around by I can't get the files to appear due to HTML!)
but still no luck (compiles fine on my computer). Any ideas?

Compile with g++ -o cgitest.cgi cgitest.cpp to get the C++ runtime libraries linked in your program.

I'm having a problem passing data on from a multi select box to another page. I can get the info passed onto the next page, but if the user has selected more than one value it goes across as a string ie. 1,3,5 - what I need is a way of telling the multi select box on the second page to take these values and show them as selected items. 
Anybody help please - I'm still learning so please keep it basic.

|

ok, before I can help (and that will tell if I can help you)....with what are you recieving the values on the next page?? ASP? CGI? HTML (with JScript)?
because basically what you need to do is separete the values, using the ", " as the indicator.
If its ASP I'll be more than glad to help you out...

Hi
Thanks for replying! The page receiving the data is ASP and yes the data needed for the drop down boxes does contain a comma between each choice where more than one choice was made. At the moment I can recall the data into the top line of the drop down box showing both values.
This is the "view source" for the drop down multi select box on the second page - as you can see its calling back the items and displaying them in the one field, rather than showing the original choices selected.
-->
Red,Blue
Red
Blue
Yellow
Purple
Gold
Orange
Green
At the moment I just have a simple <%Request("Colour")%> in the first line of the drop down box
Any help would be greatly appreciated - I've found bits and pieces of code about seperating multi select fields, but most of them use hard coded examples and then say the lovely line "of course this can be populated automatically from either a previous page or a database by seperating the multi select values" - but never actually show you !!!!
Thanks

Thanks Jon - brilliant. 
Just one small thing - is it possible to display all the items from the original box, but just highlight the selected ones on the new page - so that they can change/add to their original choices if needed ???
ie. if they originally chose red and blue, then 3 months later they want to update their choices and add yellow - the update page being the second page.
Cheers

How would I convert a letter or group of letters to upper case using regular expressions in javascript (I know you can use toUpperCase, but for the purpose of really understanding RE's, I'd like to know how to do it)?
What I tried:
alert("Jamie".replace(/\ui/, "$1");
Thanks in advance.

I tried this....
<br />
<html><br />
<head><br />
<script language="JavaScript"><br />
function convert() {<br />
myString = new String(frm.test.value);<br />
alert (myString.toUpperCase());<br />
}<br />
</script><br />
</head><br />
<body><br />
<form name="frm"><br />
<input type="text" name="test" value="test"><br />
<input type="button" value="Convert" onCLick="convert();"><br />
</form><br />
</body><br />
</html><br />
<br />
hope it works.
cya.

Hi Jonavis. Thanks for the reply, but as I mentioned in my question, I KNOW you can use toUpperCase. My reason for wanting to do it with a Regular Expression was to better my understanding of Regular Expressions.

give this a try...
${"LOCAL_ADDR"};
I got this from converting an ASP file to a PHP using ASP2PHP.

I am not really sure if it works...

I'm opening a Word doc. with IE. I some pc's, Word shows up embedded within IE while in others, Word starts as a stand-alone app and opens the document. I need to always have Word within IE. Is there a registry setting I can use to control this? Are there other ways to accomplish it?
|
|
|
|
|
I think, this is due to the IE. If the word plugin is integrated in the IE, it works fine as you want. But for lower version of IE or IE not having the plugin, it downloads the file separate and opens as a separate office doc.

Hi,
We're running into a confusing problem in which we do a select from our HR tables and dump the results into a SELECT html input control.
Things work fine until we try to grab everyone in the entire company, at which point not all of the results make it into the html control..
Is there a limit to the number of items a SELECT control can hold? Does it vary for NS/IE?
Has anyone experienced this?
thanks!

Following is a few things I tried, I keep getting:

I have tried many things and I really cant solve this. Help!
CASE 1: HTML table row
<tr onmousedown="Login()" id="rwLogin" onmouseover="document.getElementByID(rwLogin).style.backgroundColor='LightSteelBlue'" style="CURSOR: hand" onmouseout="document.getElementByID(rwLogin).style.backgroundColor='Ivory'">
<td align="middle"><font face="Verdana" color="darkslategray" size="2"><b>Login</b></font>
</td>

//Set mouseover and mouseout attributes:
foreach( DataGridItem item in this.dgForum.Items)
{
//Mouseout:
if (item.ItemType==ListItemType.Item)

Hi,
I want to print a specified HTML page if a checkbox in the previous page is clicked and also that my Web Browser should not prompt with the Print Dialog box.
I am using the Microsoft Web Browser ActiveX Control for the same:
<OBJECT ID="WebBrowser1" WIDTH=0 HEIGHT=0 CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" VIEWASTEXT></OBJECT>
And I am calling the function on window.onLoad event as
WebBrowser1.ExecWB(6, -1)
(I understand that
1 is for Prompt and Print;
2 is for No Prompt and Print
But as per OLECMD documentation, NoPrompt and Print is no longer supported and hence a search in Google revealed that -1 does this trick.
But now, very often my web server complains an error like
Unspecified error
URL: res://c:/windows/system32/shdolc.dll#previewdlg
Sometimes, IE is trying to crash and close itself and tries to send an Error Report to Microsoft. I am using IE 6 on Windows XP (with .NET Framework installed on the system).
Please suggest me an activeX Control to print without prompt.
Thanks in advance....

Hi, I want to set a delay in the ASP page and make a loop. The basic requirement is, my server supports bulk mailing of 20 mails per 10 minutes. So, my code should pump out 20 mails and wait for 10 minutes and pump out next 20 mails.. and this process repeats until my database is exausted.
Now, I need a delay routine in the ASP page to acomplish this job as a 'delay routine'. Is this possible with simple ASP or JScripts????
Thanks

Window.setInterval(func, interval,args....) should do the job. The parameter func should be the mailing function, interval is the interval in milliseconds (10000 in this case). The rest, args are passed to func as parameters. Window.clearInterval(intervalid) stops the periodic call to func by Window.setInterval(...). The value intervalid is returned by the call to Window.setInterval().
The func should execute Window.clearInterval when the database EOF is reached, ending the mail process.

I guess you are pulling this from jscripts??
Will check it out and give a try at it

Yup. I haven't had a need to do this, but I remembered seeing it in the O'Reilly book, "Javascript - The Definitive Guide." Hope it works for you.
