 no please
I havent used VS.NET but i guess there must be a link tab somewhere in the project settings where you have to provide the outfile name. there you can change the name of the exefile name.

Hello everyone
My question actually referrs to Borland C++ Builder 6.0. I'm trying to make a program minimize to the system tray using the TrayIcon sample from C++ Builder, but I get an error message:
"Cannot create system shell notification icon"
Can anyone, please, help me figure this out?
Thank you

I have a worker thread i created in a dialog box. I want to run a thread till i either press the stop button or it finds a winnner. that part works fine. But i have an edit box called number of players with an int variable of m_win; I put inside the tread m_win=counter; UpdateData(FALSE); and the program will compile and run but as soon as it hits UpdateData(False); i get an assert error in reference to wincore.cpp 884. I read the information online about it and basically its saying either its a bug in vc++ or i'm coding it wrong. I think i'm coding it wrong cause i installed all the service packs. could someone please take the time and shed some light on this for me. If updatedata(false) can not be used how can i update my data? I know i can make a button that updates it but defeats the point.
thanks,
tony

It is dangerous to pass C++ objects from one thread to// another
If a pointer to the object is passed or a handle is passed to another thread. but still the two threads are sharing the same resource, so there is still bound to be problems either ways, rite ?
When it says C++ objects is it MFC C++ object or any other object?

The comment means MFC objects. If you make up your own objects, you are responsible for making them thread-safe.
What creates the problem with MFC objects is that each thread has its own HWND<->CWnd association map. (This is used, for example, by CWnd::FromHandlePermanent().) So once you pass a CWnd* to another thread, the thread doesn't have that object in its map, so it can't get to the HWND and back.

I'm not asking you to do my work for me on this. However, how do i go about fixing it? How do i give it access to the hwnd?
I tried without luck this;
BOOL CCash3mfcDlg::OnInitDialog()
{
AFX_MANAGE_STATE(AfxGetStaticModuleState())
CMyDialog dlg(AfxGetMainWnd());
dlg.DoModal();
......
}
sorry trying to fix it just don't know how.
a small example would be great.
on that has a thread going on start and updates an edit box while it runs.

put it this way _param->_this = GetSafeHwnd();
and in the Run() proc
CYourDialog *pYourDlg;
*pYourDlg = (CYourDialog*)CWnd::FromHandle("the hwnd that was saved in the _param");

THANKs for you help. that cleared that error but now i get one more
it says run() is not a member of HWND which its not. its a member of CCASH3MFCDLG
I tried changing ts->_this->run(); to the following
CCash3mfcDlg::run();
and i get an error
C:\Downloads\cash3 mfc\cash3 mfcDlg.cpp(239) : error C2352: 'CCash3mfcDlg::run' : illegal call of non-static member function
i tried this as well
typedef struct ANOTHERTHREAD //structure for passing to the controlling function
{
CCash3mfcDlg* _this;
} ANOTHERTHREAD;
and then
ANOTHERTHREAD* ts = (ANOTHERTHREAD*)param;
it compiled with no errors but as soon as i start the thread it crashes

In the first case dont say ts->_this->run();
in the thread we had recreated the dialog pointer
CMyDialog *pDlg;
pDlg = (CMyDialog*)CWnd::FromHandle(ts->_this);
remember ?
now do this
pDlg->Run();

Thats where i'm confused. I would assume its an mfc object. if i can't pass it then how do i make it update after the thread is finished? once run completes then it stops.
if have a button onstatbutton()
void CCash3mfcDlg::Onstatbutton()
{
UpdateData(TRUE);
}
then it will update the edit box with the correct value;
so how do i make it either call a function after the thread breaks or whatever?
I even tried putting a call to the onstatbutton() after the while in run(). that didn't work either.
I'm very new to threads and mfc so my question is probably juvenile but i haven't a clue how to fix it.
P.s. I have programming windows 95 by petzold but i find that the code doesn't work unless you use this mak file that is c not c++ is there a good book that explains the win32 api for C++ USERS? AND YES I realize that c++ is c with classes. thats not the point.

Define a custom message such as:
#define UWM_THREAD_DONE WM_APP At the end of the thread function, post that message to the main window (you can pass the HWND to the thread, and then post to that handle). The handler for that message can then call UpdateData()

Hey all.
I've been trying to build a small application that does communication from my PC via the comm port (I have the protocol for my HDTV receiver and want to build a little remote control app to change the channels and such)
I don't seem to have any luck whatsoever how to go about doing this. I can make it work in VC 6 and VB using the MS COMM controls, but for some reason, when I try to bring in the MS COMM controls in VC .NET 2003, it does not create the class correctly like it does in VC 6. I tried creating the project in VC 6, making it work, and then opening it up in VC .NET 2003. It compiles fine, but then crashes immediately upon running it.
I can't find any articles on how to do this (that actually work), if someone could point me in the right direction, I would be very thankful. I've been playing with this for two days now and am getting frustrated with myself at this point! I would also like to be able to fire off another thread that sits and waits for communication to come in from the comm port as well. (So I can keep up-2-date information on my program about which channel is currently active on the receiver)
PS: I have other code that is dependant on VC 2003 that I want to tie into this project, which is why I do not want to simply build it in VB or VC 6
Any help would be appreciated.

I dont use VC.NET just plain V6.00 I look at these
http://www.codeproject.com/system/serial_com.asp?target=Serial%7CPort
there are a lot of examples of how to use the serial port, in the end you just use it the same as reding and writing files.

I have an iterator that is pointing to a certain element. I want to overwrite this element with the next one following it.
*I is the current element. But if I do ++I to get to the next element I lose my place....
I dont think *I = *(++I) is quite going to do it. (what would this do anyways? )
thanks,
ns
