Microsoft has not made any significant change to MFC. Other libraries really depends on what you actually are using.

There have been significant changes to some parts of MFC in VC7, CString for instance used to be reference counted in VC6, but is now an extension of basic_string in VC7. I think the upgrade to VC7 is much more frightening than the OS upgrade because a lot of compiler changes have been incorporated. Everything is manual, even memory leak detection has to be implemented manually, by dumping the leaks at the appropriate times for each project. Other than that you should have now problem specifying 0x0500 flag because 99% of all compiler version checking uses if(_WINNT >= blah) so if it compiles on NT 4.0 using a lower bit flag it'll compile on the Win2k  .

*now problem*, bah, meant NO problem.

In my MDI MFC app, I have a status bar pane that shows the current line number and column number. I know that to get the current line number, I simply do: int lineNumber = LineFromChar( -1 ). But I am having trouble getting the current column, anyone know how to do this? It shouldn't be too bad.

I believe something like this would work. If ctrl is your control and lineNumber is the current line number:
<br />
int GetColumn(int lineNumber)<br />
{<br />
long start, end;<br />
ctrl.GetSel(start, end);<br />
<br />
return (start - ctrl.LineIndex(lineNumber));<br />
}<br />

Which is the most efficient way to restart my dialog box application, I mean to close the application and to start it again immediately after that.
|
|
|
|
|
Hmm if design allows, I would hide all dialogs visible, spawn a new instance of the application and then finish the original instance. For user it will look the same, only problem can be in accessing shared resources (disk file or whatever) but you can take a care about that.

Is it possible to run a CGI program in a web server from a C++ client application?
TIA

That depends... is IE or Netscape written in C++?

What??? 
Do you think that will help to answer my question?
Carlos
p.s. both IE/Netscape are written in C/C++
|
|

|

you asked ... "Is it possible to run a CGI program in a web server from a C++ client application?"
IE/Netscape are client applications that send request to web servers. Sometimes these request result in the web server executing a CGI. So I guess maybe that the answer to your question is YES.
|
|
|
|
|
Yep, you're right, my question was not very clear
I should have written, how can I run a CGI program in a Web server from my C++ application? In other words, how can I send a POST/GET command from my app to a CGI-bin program?
Hope that makes sense now.
Thanks,
Carlos

IIRC, You can simulate POST by running the program, and dumping the data stream into its text input stream, and for GET you use some environment variable instead.
It was years ago I did any CGI stuff, that's all I can remember, so YMMV.

There are a lot of ways to do it. You can open a socket and implement the (relatively simple) HTTP protocol to send the raw bytes for a GET or POST and interpret the results. Or you can use an existing HTTP implementation in a library or the WinInet functions in the Windows API. Look in MSDN for HttpOpenRequest
|
|

|

yes, all you need is connect to your target server on port 80, and give it a post or get request.
Use sockets.
when you connect to the machine on 80,
send data on the socket like this ..
GET /yourfolder/yourfile.cgi HTTP/1.0\n
User-Agent: Cool Browser 3.3\n
Host: www.yourmachinehere.com\n
Accept: */*\n
After you send that on the socket, your response will look like
'
HTTP/1.0 good request
some other stuff...
then it will send you the output (cgis output, or requested file if you get htmls/ images etc. )
'
sockets, and http protocol man. i dont remember the post syntax or id write it here too, just google the http rfc's for reference.
todo....

Can anybody give me some useful advise on this problem I am having? Here's the code that is blowing up.
BOOL CMainFrame::OnCreateClient( LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
if (!m_wndMainSplitter.CreateStatic(this, 2, 1, WS_CHILD | WS_VISIBLE))
{
TRACE("Failed to CreateStaticSplitter\n");
return FALSE;
}
cout << "DEBUG 1 WooHoo I got this far!" << endl;
// First main splitter pane
if (!m_wndMainSplitter.CreateView(0, 0, RUNTIME_CLASS(CCube_IView),CSize(300,300), pContext))
{
TRACE("Failed to create top view pane\n");
return FALSE;
}
// The code doesn't get this far!
/*
* Debug Assertion Failed!
* Program : blah
* File: winsplit.cpp
* Line: 364
*/
cout << "DEBUG 2" << endl;
....

I haven't checked my splitter code - but putting streams (cout) in there might screw it up.
|
|
|
|
|
- Run the program under the debugger;
- Wait for the assertion message box to appear;
- Hit Retry;
- Inspect the call stack to see how pView ended up being NULL
I mention those steps because it looks like you're trying to debug by inspecting console output. That rarely works. Instead, use the power of the debugger - inspect variables, step into suspect code, experiment.

Hi, I have ListView that shows files on local drives and want to let user select view mode. So application starts defaultly with ListView set to LVS_REPORT and when user selects another style of view, the proper style is set using following code:
ModifyStyle(LVS_TYPEMASK,(LVS_ICON & LVS_TYPEMASK));
Or with LVS_SMALLICON instead of LVS_ICON when user wants to show large icons, of course.
In report style everything is ok. But when I switch to LVS_ICON mode, it looks like on this picture (I took a screenshot of my ListView):
ListView in LVS_ICON mode
And, when I switch to LVS_SMALLICON mode, it looks like this:
ListView in LVS_SMALLICON mode
As you can see, first row is missing (but when I for example double click on that empty space, my program handles it correctly as the items would be there.
I must also mention that the ListView I use has Custom Draw feature (so I handle OnCustomDraw()) and it is Virtual ListView (so I handle OnGetDispInfo()).
I'm really out of my knowledge...
Thank you for any suggestion!

There are several solutions. One solution is DrawText(). Another solution is TextOut().

Hello,
I was wondering if anyone had a good idea on how to convert the following...
CString strN;
strN.Format("%d", nNum); // where nNum is something like 1123456
I would like to see the output of strN equal "1,123,456"
Is there a easy way to do this?
Rob

Someone mentioned the API GetNumberFormat a few days ago. It's the fancy way of doing it. I'm sure you can whip up a quick for loop that will do it just as well.

Hey! It compiles! Ship it.

Why don t u just put a comma after the third, the sixth... char?
Just make a loop which every 3 char inserts
a comma with CString::Insert for instance.
Something like this:
for(i,from begining to the end of the cstring)
{
if(i==3or6or9)
urstring.insert(",") //not the good syntax but u get the idea across
}
Is it what u meant?
hope it s of any help 2 u.
