Okay, more on my exception problems...

The problem is this:

Our app starts up fine, and I can go into a property sheet. If I click OK in the property sheet, the app goes into it's infernal standby mode (as if I had hit the "OK" thing in the titlebar).

At first, I thought it was an exception firing, but that's not the case. When I'm in the debugger, I can step cleanly through the OnOK function, and when the program returns conrtol to CMainFrame, the app is in standby mode.

If anyone has an idea of what to look for, I'd be interested in hearing about it.

When do you show the property sheet? Before or after creating the main frame?

After, as a result of a menu item selection from the commandbar.

Now, that is truly weird... Can you show the code you use to dismiss the property sheet?

Well, not really, but here's a description of the situation:

0) Here's the code in CMainFrame that starts the prop sheet:

HideSipButton();
CMypropSheet dlg(_T("Title"));
dlg.DoModal();
ShowSipButton();

1) I have a base class derived from CPropertySheet. This base class implements a toolbar that contains the only button (Okay), as well as a header. There is no "OnOkay" handler in this class.

2) The derived class handles the button presses in the toolbar (and the button ID is IDC_PROPSHEETOK).

2) There are two property pages on the sheet, created dynamically 9and are deleted when the property sheet is dismissed.

3) When the user presses the okay button, the propertysheet calls a public "okay()" method within each page object. These okay() methods simply tell a globally declared object to save the appropriate data to a disk file. Afterwards, the propertysheet calls "EndDialog(IDOK)".

4) In CMainFrame (where I instantiated the propertysheet), there is no additional programming other than re-showing the SIP button. I tried removing the showing/hiding of the SIP button ut that had no effect on the problem.

-----------------------

I initially thought that an exception might have been thrown as a result of trying to write the data files in step 3, but the property sheet is terminating normally with no excpetions, and no memory leaks.

The program itself is still running, but it's almost like the program received the hibernate command from the OS...

Voice call using phone

misha_grewal6-Jan-04 1:21

I want to be able to manage a cellular phone book (CDMA phones ) via PDA (pocket PC). Is it possible to dial a number from PDA which will tell the phone connected to make a voice call. Basically can i use some API (TAPI) on PDA to make a voice call using Cellular phone. When the line gets connected I'll start talking on the cellular phone.. but the PDA will dial the number for me from the phone book which is there on the PDA?

Any ideas appreciated..

Check the AT commands from the Nokia documentation. There is a command that does exactly what you want (I've already done that).

Check these AT codes:

Start a voice call: ATDT nnnnnnnnn; (semicolon needed).

Hang up the call: ATH

Answer incoming call: ATA

Thanks, I am now aware of how to use AT commands as such. I was looking for some TAPI API for this. I want to have this coded in one program.Can I use these AT commands prgrammatically?

Thanks in advance..

I'm not sure I understand your question. Can you please explain it a little more?

I have used the AT commands through a direct serial connection established over cable, infrared and bluetooth. Never tried it with TAPI...

Here is my requirement
I have to code a phone book manager on PDA. This phone book manager will manage a phone book of a CDMA phone connected to the PDA via a data cable.So the program should be able to update the phone numbers on the phone and also it should be able to dial the selected phone numbers on PDA. Like I open the phone dialer on PDA, select a number and tap dial. this dialing should be a voice call. i.e. once I get connected(This also should be indicated by my PDA program ), I would just pick up the phone and start talking. So rather than managing the phone book on the phone I would manage and work on the same phone book using the PDA.

So is it possible to write a program say in eVC which would do the same. I checked some TAPI options like LineMakeCall etc. But I didn't get specific answer to this requirement.

Thnks in advance..

Wow! They're still using the original Hayes modem command set! AT stands for Attention; what follows is the actual command - D = Dial, T = Tone dialing (rather than Pulse, which most phones at the time still used). ATH0 = On Hook (hang up), ATH1 = Off Hook (talking). Big Grin | :-D

Communication between Phone and PDA

...are a pain in the ass.

When I click ok in a dialog box, the whole program shuts down. I'm pretty sure it's an file exception that's being triggered, but grrrrrr....

Just wanted to vent a little. I now return you to your own local copy of hell.

I would like to know abt the details of communication between PDA and a GPS phone via Serial Port. Can i open a COM Port on PDA and then communicate via that port to the phone using a Data cable or something?

You can read about the basic principles of serial communication with a mobile phone here:

Infrared Communication with your Mobile Phone[^]

The article discusses IRDA, but you can apply these principles to Bluetooth and serial cable as well.

I've created a mobile application which saves data to the SQL CE in the pocket pc. There is a main server which run SQL Server 2000; and is the main database for the client. Is it possible to synch the data inputed in the pocket pc with the one in the main server?
