Hi all
I'm not a programmer but I'm looking for someone with C++ knowledge and maybe knows a little about VOB files (DVD's) to help me with my small project to play a single VOB file
I've searched high and low for help yet I just can't seem to find someone
I hope I haven't broken any rules but I can't see where else to ask for help 
thankyou

Maybe try talking to guys from Gordian Knot project (http://gknot.doom9.org/[^]).
And what is your project exactly?

One class, which is connected to a dialog box, is handling a OnTimer message just for that class... how can I hide the dialog box and allow the user to use the main view, which its disabled if the dialog is sent the ShowWindow(SW_HIDE)? Does the dialog box need to be a modeless , I wouild prefer it would be a modal.
I would rather not pass the SetTimer to the main view class.. it would get very messy if it did.

Yes the Dialog has to be Modeless
otherwise you will have to create a GUI thread (not pretty;))
BTW why not modeless ?

I just returned it to the main timer in the view class and gave it a different UID.
Thanks anyways... a thread would have been overboard for it.

HI all!
I have a very simple question to ask...
I have a small program that i play with and it very simple
it call LED program, the program have a basic function like
"Reload" the script file, "Start", "Stop", "Exit", and "Clear".
and it all work just fine but the question that i have it
how can i make the program to Start auto without click on "Start"
Every time i run the program i have to click Start then the program run the scripts
and(or) is there s way that i can add right click on the icon on the system tray and start the program, instead of open the program to main menu and click Start.
Thank in advance

Try to be more precise.
If it is a dialog-based application, you can call Start() method in CYourAppDlg::OnInitDialog().

Sorry i didn't be more precise.
Yes, it is a dialog based application
here is the code that i was calling for the case to start the app when i click Start or Stop ect.,
that is in my "led.c" file
<br />
BOOL CALLBACK DialogProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)<br />
{<br />
if(wParam==SYSTRAYBUTTON&&(lParam&3)==3) {<br />
<br />
Shell_NotifyIcon(NIM_DELETE,&nidata);<br />
ShowWindow(hDialog,SW_SHOW);<br />
<br />
SetForegroundWindow(hDialog);<br />
}<br />
<br />
switch (message) {<br />
case WM_INITDIALOG:<br />
return TRUE;<br />
case WM_COMMAND:<br />
switch(LOWORD(wParam)) {<br />
case IDRELOAD:<br />
timeKillEvent(timerid);<br />
load_cfg();<br />
curtimes=0;<br />
curframes=0;<br />
curtime=0;<br />
curframe=0;<br />
change=0;<br />
timerid=timeSetEvent(current->delay,current->delay,TimeProc,0,TIME_PERIODIC);<br />
return TRUE;<br />
case IDHIDE:<br />
ShowWindow(hDialog,SW_HIDE);<br />
Shell_NotifyIcon(NIM_ADD,&nidata);<br />
return TRUE;<br />
case IDEXIT:<br />
PostQuitMessage(0);<br />
return TRUE;<br />
case IDSTOP:<br />
timeKillEvent(timerid);<br />
return TRUE;<br />
case IDSTART:<br />
timerid=timeSetEvent(current->delay,current->delay,TimeProc,0,TIME_PERIODIC);<br />
return TRUE;<br />
case IDCLEAR:<br />
timeKillEvent(timerid);<br />
{<br />
char *buf;<br />
buf=calloc(64,1);<br />
refresh(buf);<br />
free(buf);<br />
}<br />
return TRUE;<br />
default:<br />
return FALSE;<br />
}<br />
case WM_DESTROY:<br />
case WM_CLOSE:<br />
PostQuitMessage(0);<br />
}<br />
return FALSE;<br />
}<br />
and this is what it look like when in dialog
http://thanhmai.virtualave.net/led.jpg[^]
and all i want to do it let the Program to run when i open the program.

I guess that this happens when you press the Go button:
case IDSTART:<br />
timerid=timeSetEvent(current->delay,current->delay,TimeProc,0,TIME_PERIODIC);<br />
return TRUE;
Am I right? If yes, put the timerid=timeSetEvent... line in WM_INITDIALOG. You will have something like this:
case WM_INITDIALOG:<br />
timerid=timeSetEvent(current->delay,current->delay,TimeProc,0,TIME_PERIODIC);<br />
return TRUE;
This should do the trick. If it does, let me know. And if it doesn't, you can send me the code and I'll work it out.

Hi chopeen,
Yes, you are right it happen when you press the Go button: i have try to use your method and it didn't work it compile and when i try to run the app i get and Application Error
"The instruction at "0x00401447" referenced memory at "0x00000008". The memory could not be "read".
here is what i add to the code:
switch (message) {<br />
case WM_INITDIALOG:<br />
timerid=timeSetEvent(current->delay,current->delay,TimeProc,0,TIME_PERIODIC);<br />
return TRUE;
maybe i try it again tomorrow, right now is 4:00 AM and i just get back home from work and check the message and try it see it work but not.
here is a block section of the code that the DIALOG INIT
BOOL CALLBACK DialogProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)<br />
{<br />
if(wParam==SYSTRAYBUTTON&&(lParam&3)==3) {<br />

Looks like the current object (whatever it is) is not initialized, when you start your app.
It means that there is something before IDSTART that does it.

Another solution is a timer.

thank, but i don't want to do with any timer
my program have a time delay when it open up and it init the dll driver for
parallel port and then it load the ledcfg.txt and it sit there until i click
start the program.

Using Microsoft .NET 2003, Visual C++
After compiling a project, when I run the project, I get a dialogbox saying the project is out of date and if I want to comile it.
If I respond Yes, it seems to be compiling the resources. I've checked the dates of resource files, all seems ok.
What can be causing that ?
happy holidays.

I found my problem...
There was a conditional compile directive in the .RC file that was spanning on two lines with a '\' line break. I removed the '\' line break so that the directive fits only on one line. That made the 'out of date' message go away.
I found this line by looking at the BuildLog.htm result file. There was an entry stating that a file 'define(_DEBUG))' could not be found.
Not to sure how this happened. I never edited that file by hand. This project was converted from VC6 to VC.NET by VC.NET, but was not doing that problem after convertion. Happend at some point after.
anyways, it is solved. Thought I was going crazy 
Thanks for the spiritual support
Louis.

As a Winapp non-professional programmer, off and on for personal projects for many years, I've always tried to use the Win32 API as directly as possible. So...I've kinda disliked the whole MFC concept for quite some time. Yep, Petzold's first books were my programming bibles.
Unfortunately, MFC doesn't seem to be going away and my current project requires the use of parts of it (especially for easy CDatabase functions). Therefore, the app will be written in the "Microsoft ordained" MFC style...
The app requires high-performance threads that are used to compute millions of FLOPS. This is where using the traditional Win32 API calls was nice.
Are there any performance penalties when using MFC as it "wraps" so much stuff into the code behind-the-scenes?? In other words, is it to be expected that MFC programs operate at 80 to 90% of their straight Win32 counterparts??
Like I said, it was always more fun (and less worrisome) to get as close to direct access to the hardware as possible.
Thanks!

a) You can use the bare minimum of MFC you want to, and still call straight into the Win32 API - and you can usually pull any required handles straight out of any MFC objects you have.
b) Lower application performance is an acceptable trade-off for a similar reduction in development time. MFC isn't in my experience particularly slow, as most of the calls in MFC are pretty "thin" and usually go straight into the matching Win32 calls anyway. Add in the extra useful bits (CString and the collection classes), and you save yourself a lot of headaches

Thanks, Ian, for the information regarding the use of MFC versus the Win32 API. It sounds like the MFC "objectification" of various Win32 API functions doesn't impede the processing all that much and that's good. It reminds me of when I started to use C for Windows apps (Petzold's first book). I'd be writing in C but still need to inline some assembly code to get that extra graphics performance. Now, it's C++ using MFC and "inlining" some direct Win32 API calls!! And, no direct hardware access anymore (don't know how to write my own custom device drivers yet either)...
The project I have going is a full-blown jukebox type application with DSP routines that I've learned through various books. I've left the FFT routines up to the guys of FFTW.com (they've done an excellent job fine-tuning the performance of the FFT in their libraries!!). In the current Win32 version I have going, there are separate high-priority threads for the audio playback and then the DSP math portions (if they get interrupted, you HEAR the problem, haha) and then a standard thread for the GUI.
It is only a personal project - nothing for sale - and perhaps it'll turn out good enough (and interesting enough) to be on this site in the future.
Thanks again and have a great holiday season.

Yes and The MFC Message Routing architecture is faster in some cases than a standard switch..case statement in WIN32

I really like the class because it's so easy to use. However i have a few problems with alpha
Creating an image with:
MyImage.Create(width, height, 32, CImage::createAlphaChannel);
Results in no alpha at all and when creating like this:
MyImage.CreateEx(width, height, 32, BI_RGB, 0,CImage::createAlphaChannel);
i get a completely transparent Image even if i set every pixel to 0xffffffff.
