I suppose your main window is not the dialog... Please show the code where you call the dialog.
|
|
|
|
|
i am creating and calling the cdialog in the CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) function and i am creating my CWnd in the int CClientView::OnCreate(LPCREATESTRUCT lpCreateStruct).
|
|
|
|
|
Try to remove the dialog invocation from the CMainFrame::OnCreate. Move it to the Application's InitInstance. If the user fails at entering the application, you can immediately exit it (will not create the main frame).

It works... Thanks!

Hello. I am a final year student in electrical and electronics engineering. I am taking up a project on a path finding system.The system is to seek the shortest and fastest distances between two locations on a map with considerations of the number of traffic lights and timing of the traffic lights. I am looking for source codes for a Global Positioning System (GPS) software to be run on a pocket PC.I am unsure of which platform to use, Access , Visual Basic or SQL.
The guys in Telmap and mapopolis are doing it, but how?
I hope to hear from anyone who is interested.
Thanks.

Hi,
Stay away from Visual Basic. Pocket Access is usable but not very powerful. If you want raw power in your application, there is only one way to go: C++ and SQL Server CE 2.0.
GPS receivers generally work through the COM port. I have some code for that, but perhaps you want to check out this book first:

Hi all,
I've been assigned the task of obtaining a number of handheld units.
The idea is to write a some database app on them to facillitate mobile data collection.
Then at the end of every day they upload (either by docking/wireless/phone) to a central server.
Anybody any input to help me.
At the moment I don't even know what platform to choose!
Sounds like a common task - are there any good solutions out there already?
Any advice welcome before I take the plunge.
Cheers

That sounds like a very common request. And, really, most mobile platforms will fit the bill you need. My experience with the Pocket PC allows me to tell you that it does support a very interesting number of databases and connectivity methods. You can use Access, SQL Server, Oracle and many other db engines. As for connectivity, you have a full spectrum of access methods, Bluetooth-enabled GPRS, Wi-Fi, cradle, the works.
So, it is an excellent choice.

Thanks for your feedback... I think I'm going to go the Pocket PC route, just wanted to check nobody had hit any real headaches!
Anybody know any durable units in the field?

It depends on the application type, but you can rely on HP and Symbol.

Well the handhelds will be used on the wards in a hospital for a new trial we're doing.
I've fallen out with HP at the moment because of their appauling OfficeJet drivers and support so they'd be my last resort! I guess it couldn't hurt to look at their stuff though!

I also need some help in understanding your question... 
Well, if you are asking about how to create an install package, you really need to read about it in the online help file. Go to the following topics: Microsoft Windows CE / Installation and Configuration Guide / Installing Applications. This will teach you how to produce a CAB file with your deployment. Then, you can do one of two things: copy the CAB file to your device and execute it, or use the CeAppMgr.exe residing in your desktop to do this work. The online help file has one example of the scripting you need.
If you need more help, get back here.
Good luck!

I knew that we use Unicode on PocketPC. But when I type a Vietnamese text, it can't be shown correctly in screen. Why ? I think it's not problem when I use a Vietnamese text with Unicode, but it seems not like that

I want to use both English and Vietnamese in my eVC program. When I choose an option "Using Vietnamese", every dialog and text that appear then in Vietnamese. And the same to English.
What is the best solution ?
Thanks in advance

Great, I now have a Java-enabled phone, a Nokia 3410, and being a geek, I would like to program it - but how?? 
Could someone point me in the right direction for tutorials, SDKs etc? Thanks a lot, because a quick Google search provided nothing I though useful.

The CStdIoFile class is available for use, but none of the functions in it are supported. How f***in' absurd is that?

You're right! Sometimes I have the feeling that MFC 3.0 for CE is really a half-baked and, in some points, a poorly implemented library. This kind of things just makes me wonder how fast the MFC team had to adapt the library for CE. Way too fast.

I am running Windows CE.
I want to trigger a function every 30 minutes. I understand that this can be done by using timers. But a timer object needs DispatchMessage() function for TimerProc() to get called.
Is it possible to provide a message loop in a windowless DLL? If yes, where should the message loop be defined?
(I tried providing a message loop in the DLL but the DLL started showing strange behavior. Is it at all possible?)
Windows ce does not support Timer Queues or Waitable timers. Is there any other option?
Any suggestions would be highly appreciated.
Thanks,
Ruchika

Another option would be to use a thread. Worker threads do not need a message loop and you can control their timing with equal (if not greater) accuracy. The code would look something like this:
BOOL bLoop = TRUE;
while(bLoop)
{
Sleep(30*60*1000);
}
Please note that this code might not be the best for battery saving purposes.

Thank you so much for the suggestion.
I am leaning more towards not adding a background thread mainly becz I already have three threads in my module. So, I am thinking of modifying one of the threads that I have to wait for RETRANSMIT_TIME, do the job and again wait.
