why would you do someone's class assignment for them?

If it's really an assignment the teacher will know straight away: some who can't program in C++ properly using back inserters, stream iterators and algorithms is a dead giveaway. If your assumption is incorrect then I've helped someone out.

:-DI have a method of event interface,for examples declaration is Fire_MyEvent(VARIANT v), I make the variable v like this:
CComSafeArray<VARIANT> arr;
arr.Add(CComVariant(buffer));
arr.Add(CComVariant(m_sScreenName.c_str()));
arr.Add(CComVariant("AIM"));
arr.Add(CComVariant(list.c_str()));
CComVariant v(arr);
Fire_MyEvent(v);
It works well in my VC program, but when I used it in a Dephi program, there is a problem.
In dephi function like this:
OnMyEvent(OleVariant v), when run , the v is null, why?

Has anyone see the IE "Favorites" menu, it has the amazing abillity to accept files dragged inside the menu, you can also move items arround by dragging items up and down.
I've been told that i shuld manipulate the WM_MENUDRAG message, but MSDN has documented this very poorly, it seems that the documentation / source to archieve drag & drop on menus is very hard to find if not impossible.
Any tips ideas from u guys, are welcome !

I'm writing a ActiveX plugin to display video, I have problem on OnDraw method, I can't refresh received images on the display zone:
//Draw method:
HRESULT OnDraw(ATL_DRAWINFO& di)
{
RECT& rc = *(RECT*)di.prcBounds;
if( ImgBuff )
{
HBITMAP HBmp = CreateBitmap(ImgBuff->width,
ImgBuff->height,
1, 32, ImgBuff->data);
DrawState(di.hdcDraw, NULL, NULL,
(long)HBmp, NULL,
0, 0,
ImgBuff->width,
ImgBuff->height,
DST_BITMAP);
DeleteObject(HBmp);
}
else
{
.......
}
return S_OK;
}
//Buffering method
//this fonction bufferise recived image in ImgBuff
FrameReady(phVideoFrameReceivedEvent_t *ev)
{
ImgBuff = ev->frame_remote;
FireViewChange();
}
Thank you to say me how to redraw a new image the display zone??

Hello
my pb is:
when I create a std::map in an exe and pass it to a object's method in a DLL, I can't access to the elements of the map (it crashs after the first access).
You can try this minimal code illustrating that.
(I work under visual C++ 6, but I think it's not the reason).
the code: a main.cpp file: the "application".
dll.h and dll.cpp : the dll with the object's method:
main.cpp___________________________
#pragma warning( disable: 4786 )<br />
<br />
#include <map><br />
#include <iostream><br />
#include <string><br />
#include "dll.h"<br />
<br />
int main ()<br />
{<br />
std::map<const std::string, std::string> l_map;<br />
std::map<const std::string, std::string>::iterator it;<br />
int i;<br />
<br />
l_map["1"] = "2";<br />
l_map["3"] = "4";<br />
l_map["5"] = "6";<br />
<br />
for (it = l_map.begin(); it != l_map.end(); it++)<br />
{<br />
std::cout << (*it).first << ": " << (*it).second << "\n";<br />
}<br />
<br />
CDll obj;<br />
obj.f(l_map);<br />
<br />
std::cin >> i;<br />
return 0;<br />
}
dll.h________________________________________
#pragma warning( disable: 4786 )<br />
<br />
#include <map><br />
#include <iostream><br />
#include <string><br />
<br />
#ifdef DLL_EXPORTS<br />
#define DLL_API __declspec(dllexport)<br />
#else<br />
#define DLL_API __declspec(dllimport)<br />
#endif<br />
<br />
class DLL_API CDll<br />
{<br />
public:<br />
void f(std::map<const std::string, std::string>& p_map);<br />
};<br />
dll.cpp________________________
#include "dll.h"
<br />
void CDll::f(std::map<const std::string, std::string>& p_map)<br />
{<br />
std::map<const std::string, std::string>::iterator it;<br />
<br />
for (it = p_map.begin(); it != p_map.end(); it++)<br />
{<br />
std::cout << "DLL: " <<(*it).first << ": " << (*it).second << "\n";<br />
}<br />
}<br />
Thank you in advance for your help.

Its not crashing with given code. I'd tested it.

Did you compile the DLL with the same threading model and compiler as the EXE? If not, that's probably your problem.
|

Hello again.
A piece of "solution":
it seems only the map has this problem (but I don't try with a std::list for instance)
passing a vector of pair works.
But we loose the sort advantage of the map (I don't car in this case, ouf  )
Maybye the problem is the implementation of the stl map in microsoft visual C++ 6.0 (I don't try to compile yet with other compilos)

I suspect you need to compile the code with a DLL version of the C run-time library. Otherwise, the EXE and DLL use different heaps, which causes problems when you pass things with heap-allocations (like STL containers, for example!) from EXE to DLL and vice-versa.
To change the run-time library version, open the project's settings and select the C++ tab. Then select 'Code Generation' in the 'Category:' drop-down list. Then, in the 'Use run-time library:' drop-down list, select 'Multithreaded DLL' (for a Win32 Release configuration) or 'Debug Multithreaded DLL' (for a Win32 Debug configuration).
HTH!

Bingo. I'd bet that's what's going on here.

We need to record all javascript events fired/registered against any HTML element on a form.
For example,if there is a SELECT element on a form,and there is a javascript function registered against the onchange event of the element,we need to shortlist the 'onchange' event.
How do we do this - is there some way to identify the events against which javascript functions have been registerd for any element - (either through IHTMLDocument interface or attachEvent DOM)
The purpose is to trigger that event programmatically - i.e we would populate the SELECT element and trigger the javascript 'onchange' event(or any other 'javascripted' event for that matter) through FireEvent.

Compiling in VC6 with STLPORT 5.1.0 and MFC
I'm experiencing the following messages.
Anybody can help to solve this ?

Maybe this could help: I've got on codeproject list a (now broken) link to a solution: http://www.codeproject.com/file/win32findfile.asp?df=100&forumid=13624&exp=0&select=925545#xx925545xx
Following it, I found this notes. However them does not suggest me any solution.

Are there equivalent classes in WTL that replaces the MFC CFile-based classes?

There is a CFile class written by Bjarke it must help you in your work.
You can find that here
http://viksoe.dk/code/atlfile.htm

I believe in luck and i find that the harder I work,
the more I have of it _-_::

John, check out CAtlFile. Personally, I use STL streams (std::ifstream and std::ofstream).

I need to use the _access function in io.h, but when I #include it, I get the following linker errors:
1>LIBCMT.lib(dosmap.obj) : error LNK2005: __errno already defined in atlmincrt.lib(atlinit.obj)
1>LIBCMT.lib(dosmap.obj) : error LNK2005: __set_errno already defined in atlmincrt.lib(atlinit.obj)

1>LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
If I *don't* #include io.h, I get a compiler error saying _access isn't defined.
If I try to #include atlmincrt.h, the compiler tells me it can't find the file, yet the ATL include folder exists in the VC++ Directories, and the file is in that folder.
Is there a secret atl include file that solves this problem?

Are you getting this error for Release builds only?
Try removing _ATL_MIN_CRT in Project -> Settings, C++ tab, from the Preprocessor definitions box. [edit]This is for VC6, but their might be something similiar in VS2005, but I don't have access to it right now[/edit]

50 cups of coffee and you know it's on!

What Steve said. Is VS2005, open the project settings and in the General section make sure the Minimize CRT Use is ATL is set to No.

That was it. Many thanks.

I'm using VS2005 Standard
I'm completely new to WTL, and have downloaded 8.0.6034 from sourceforge. How do I "install" the app wizard stuff? The installer appears to be a javascript file, but when I try to load it in IE, nothing happens. The documentation doesn't appear to say how to run these setup files.

Close Visual Studio and just double-click the "setup80.js" script.
