Obviously having this work under a true cross platform umbrella is beyond the topic of this message. Right now I'm curious on just how hard or if anyone has been successful in taking some of the most excellent MFC controls found here and converted them to work under wxWidgets. I'm particularly interested in the XListCtrl since that is basically a control that always wows me and I feel having something like available under wxWidgets would be awesome.
I'm not asking that others do it for me, I'm just curious on if anyone has tips on where to start first and the best method to tackle it. If it's not possible or requires to completely re-invent the wheel, then maybe it's a bit over my head.
Thanks!

I've been playing with wxWidgets for a year or so now but mostly just to have a GUI interface for testing my machine vision tools. I used MFC for a long time before. It should be possible to do it since it's all just programming and there seems to be a very high correspondence between MFC message handlers and the handlers in wxWidgets.
I'm not familiar with the control you mentioned but a potential problem is where the MFC class is just a wrapper for a Window's control. In that case if you're looking for a truly cross platform solution, then it gets a lot tougher since the underlying control won't exist on other platforms or if a similar control does exist, you'll have to do essentially multiple implementaions under the covers to make it transparent at the top level.
MFC being Windows specific allows you get get to and use the underlying Windows API pretty easily and depending on how much that has been done may cause problems, too.

Your teacher?
I'm being serious. I would hope the project is within the abilities of someone who's been paying attention during their course.
Is this an idea you thought of yourself? Is it specified homework?
Break your problem into managable bits. Can you write a console program? Have you done a timer? Refresh the screen? I wouldn't use a console for a game, but still... [*]
Can you parse input?
All these questions should be answerable for you. If not, you've chosen too challengina project, or you need to reread your notes.
Good luck,
Iain.

Hi all,
I'm new to JavaScript and Google Maps API. I got some problems but I cannot find out the reason. Hope someone can help me.
What I tried to do:
I'm trying to develop an application in MFC (Visual Studio 2005) with a html dialog showing a Google map. I will send location data from the MFC application to a JS function to calculate directions. Another JS function will return the number of routes and steps in the GDirection object. The result will be sent back as a message string. The codes I used for the HTML dialog was downloaded from CodeProject.
The problem I encountered:
If I open the html file using IE and manually input the location data and use alert function to show the message, everything works well. I can also send the location data from MFC to JS. However, after that, I cannot get the route number back... It always returns the number as "undefined".
Some codes:
function initialize() {
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map_canvas"));
gdir = new GDirections(map, document.getElementById("directions"));
GEvent.addListener(gdir, "load", onGDirectionsLoad);
GEvent.addListener(gdir, "error", handleErrors);
}
}
function UpdateGPS(ar) // this is where MFC send the location data to JS
{
var a = new VBArray(ar);
var b = a.toArray();
rExp = /(\w|\s)*[^@]/ig;
var res = b[0].match(rExp); // Name @ size @ free_space
lan = parseInt(res[1]) / 1000000;
lon = parseInt(res[2]) / 1000000;
str = lan + "," + lon;
setDirections(str, "1.300983,103.772704");
}
function getRoute() // this is where JS should send information back to MFC
{
return message;
}
function setDirections(fromAddress, toAddress)
{
gdir.load("from: " + fromAddress + " to: " + toAddress, {getPolyline:true, getSteps:true, travelMode:G_TRAVEL_MODE_WALKING});
}
function onGDirectionsLoad()
{
n_route = gdir.getNumRoutes();
message = str + ". we have " + n_route + " route.";
alert(message);
}
Can someone help me here? Thanks a lot!

HI,
I got some code to load png image in button but it is giving error:
Could you suggest what might be the reason?
HBITMAP hBitmap;
Bitmap* bitmapfile = new Bitmap(L"test.png");
Status status = bitmapfile->GetHBITMAP( NULL, &hBitmap );
::SendMessage(m_imageBtn.GetSafeHwnd(),BM_SETIMAGE,(LPARAM)(DWORD)hHandle,0);
Error:"'Gdiplus::GdiplusBase::operator new' : function does not take 3 arguments"....

Hi,
I am working on a project, where i see a declaration of a thread local variable as below.
__declspec(thread) long g_nLock[2] = {0, 0};
And this variable is accessed with InterlockedXXX functions.
My doubt is, this variable will have the global memory local to every thread.
In that case, is it required to use InterlockedXXX functions to access the variable?
If i change the allocation and access method of this variable using TLS APIs,
do i have to take care of locking?
Thanks in advance.
Selva

I'm not familiar with whatever the TLS API is, but if you're accessing this variable from multiple different threads directly, you have to lock it. If you want to get around this, use only one thread to change it and post signals or windows messages to that thread telling the variable to change, that way you (probably) won't get any weird conflicts.

You are correct, each thread will have its own copy of g_nLock that no other thread can see or modify. As such, it doesn't make sense to modify it with an Interlocked*() function.
The same would be true for any blob you associate with a TLS index via TlsSetValue().
Note: Be carefull using __declspec(thread) in dll's, read the MS docs (this may no longer be an issue in VS2010 ?).
...cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

hi

SYSTEMTIME st;
GetSystemTime(&st);
this one give wrong time...please any body
|

In the documentation for GetSystemTime[^] it states "Retrieves the current system date and time. The system time is expressed in Coordinated Universal Time (UTC).".
It's time for a new signature.

I use a SMTP client class in VC6 MFC project , it function , but it bother me some warnings :

and I have #pragma warning(disable:4786) in top of file , but obvious don't function ..... how to solve these warnings ?

I want to do this without lowering my compiler warning level , if is posible ...

It is a bug in VC6. For more information see here[^].

Thanks , I solved the problem inserting
#pragma warning(disable:4786)
before to
#include <vector>
this class use
std::vector <std:string> Attachement;
could I fix the problem without '#pragma warning(disable:4786)' ?

This would be better:
#if _MSC_VER <= 1200
#pragma warning(disable:4786)
#endif
Don't inflict hacks on compilers that don't need them.

IMO, No.
This warning is caused by STL itself and you can disable it only for STL headers. See this[^] article for details.
