If you installed a keyboard hook, then you could have each of your windows 'subscribe' to your keyboard hook. When you saw a key come through, post the message to each of your subscribed windows. That way, a single keyboard event, normally only targeting a specific window, can appear in multiple windows.

Actually my final project in that class in college went a step farther. Yes we had to do all that you did above (pretty much), but I also valued the number of rentals until replacement. Then you take your rented videos and sell them as used, but all the results are profit because you already went past your number of rentals to pay for the tape. The manager could select how much profit he had to achieve before moving the rentals to used sales (he might want to rent n number of times past breaking even point). Overhead for the store was distributed to the tape market and could be distributed linearly, or based on popularity or any percentage between the two.
It was a pretty cool project all together. Since it went well above the requirements of the final project (which was just rental sales, cashier type stuff -- even had to determine change to the customer)... well, I modified the terminal during the late night shift so I could up the baud rate on the terminal to well beyond the limited 9600 the other students had... also upped my priority for cpu time such that debugging and processing of the rental library went faster... though I did experiment with 4D data structures to store the data in, pretty fun assignment!

hi,i have one dialog called "main" and another "login", when the program starts, "main" starts and in the OnInitDialog() it calls another dialog called "login" and the main is hidden using ShowWindow(SW_HIDE). From the "login" dialog how can i show the "main" dialog without restarting it and hence the OnInitDialog() starting again.
or how do i pass a variable from "login" to "main" to use in an if statment in the OnInitDialog() to indicated the "login" has previously been called
hope i make some bit of sense!!
thanks

If you display the "login"-dialog with a call to DoModal() from the "main"-dialog's OnInitDialog(), the "main"-dialog won't be displayed until the user have dismissed the "login"-dialog.
Save the status depending on whether the login procedure was successful or not in a member of the "login"-dialog so that it can be retrieved when the execution continues in the "main"-dialog's OnInitDialog().
If the login procedure failed, simply use PostQuitMessage() to close the application or take whatever action you like.
Hope this helps

thanks for the reply
PostQuitMessage(0); does the job alright that i was looking for.
but for future reference i would still like to know how to pass variables between dialogs
say declare a int in "main" and pass it to "login" and "login" sends it back with a value inside it.
thanks

It depens on the type of dialog you are using. For non-modal dialogs you can send a message the same as you would send any other message, using SendMessage() specifying your own paramaters for lParam and wParam.
But with Modal dialogs, the main dialog is halted until the child dialog is closed. You are able to send a message from the child to the parent using PostMessage().
Another method is through the use of global pointers. I'm sure there are other methods, but the above 2 have always fulfilled my needs.

catch the return value like this :
CMainDlg::OnInitDialog() {
CDialog::OnInitDialog();
CLoginDlg dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDCANCEL) {
this->EndDialog(IDCANCEL);
}
return TRUE;
}

Does anyone know if it is possible for cold fusion to access a c++ dll.
I am specifically trying to use cold fusion to access a blowfish(encryption algorithm C++ dll).
1. Is it possible within the cold fusion framework
2. If so, can someone tell me or point me in the right direction?

Hello everybody,
A week ago or so I have posted a message with the same title. I have solved this problem. But now I ve got a new one. I do the following:
Start recording with the wave audio input device.
Using the function waveInStart()
During recording all waveheaders that are returned to the application are processed and added to the wave audio input device again.
Using the function waveInAddBuffer()
Driver messages are processed using a dedicated thread. (Using the flag CALLBACK_THREAD in the function waveInOpen)
After recording for a while the recording is stopped.
Using the function waveInStop()
Now I need to mark the last waveheader with a time stamp. Before I stop the wave audio input device I query the current sample
using the function waveInGetPosition() (All waveheaders are of the same size)
dwLastWaveHeader=(dwCurrentSample-1)/nSamplesInEachWaveHeader;
Oke this works. But in some very very rare cases the current data record is not returned to the application. (Happens when the current buffer is only filled for say 200 samples and less)
My question is how to make sure that the current buffer is returned to the application? 
Thank you
|

waveInReset
The waveInReset function stops input on the given waveform-audio input device and resets the current position to zero. All pending buffers are marked as done and returned to the application.

Hello Blake Miller,
Thank you for your reply!
I know that waveInReset returns all pending buffers to the application. But it returns all buffers with the dwBufferLength member marked to 0 on my system. Even the buffer that contains say 200 samples. (The buffer that was not returned using waveInStop) I am sorry but I don't think this would solve the problem. (I ve tryed it on my PC and on another PC)
Thank you

I'm writing a user interface with Visual C++ 6 on a computer with English as the working environment.
I have Chinese script that I can see in Excel and RTF files. It uses a SimSun font. I want the same script to appear on a button using SetTitle. I compile successfully with UNICODE defined. However, I can't figure out how to get the characters into the code. Any ideas?
ie wnd.SetTitle(_T("????"));

I often have problems writing Chinese into my code using VC6, though for me each character takes up the space of 2. ie. the caret is able to position itself in the center of a character. It's annoying sometimes, especially when trying to edit the end of a line which has Chinese at the beginning.
A work around I often use is to write the function in notepad or something similar, then copy the whole thing over to MSVC.
I have just downloaded the 2005 edition, I hope this has been fixed.

You need to use escapes to put non-ASCII characters in source code. Figure out the Unicode code points of the characters, and do something like this:
wnd.SetTitle(L"\x341f\x98bc"));
(those are made-up values)

Cool.
Any hints on figuring out the code points. I could put the characters into a unicode configured text file, read the strings with a C++ program and print out the hex values. Is there an easier method or a utility available.

I must be close but...
Using your method (thanks), my hex values are \x62a4\x6797.
But I get empty boxes. When I use \x2021, I get the double dagger symbol.
My code is basically,
...
CFont font1;
font1.CreateFont(13,0,0,0,FW_NORMAL,FALSE,FALSE,FALSE,0,OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH|EF_DONTCARE,_T("SimSun") );
Button.SetFont(&font1, TRUE);
Button.SetTitle(_L"\x62a4\x6797");
...
What am I missing?

You need to set the charset parameter correctly. For Chinese, there two - CHINESEBIG5_CHARSET and GB2312_CHARSET. One is simplified, one is traditional, I can never remember which is which. :->

Hmmm. I tried both. I compile w/o warnings But I still get two squares and a dagger with (L"\x62a4\x6797\x2021"); . Any ideas?

This works for me in a WTL dialog-based app
LRESULT CMainDlg::OnInitDialog(UINT , WPARAM , LPARAM , BOOL& )
{
CButton btn = GetDlgItem(IDOK);
m_font.CreateFont ( -13, 0, 0, 0, FW_NORMAL, false, false, false, CHINESEBIG5_CHARSET, OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH|FF_DONTCARE, _T("SimSun") );
btn.SetFont ( m_font );
btn.SetWindowText ( L"\x62a4\x6797" );
}The only change I made was the font size and char set params to CreateFont()
