Hi y'all:

I have a iPAQ HP 5550 with winCE 4.2 and i want to read from serial port using evc++ 4.0. I have written this code, and it works (it reads) but it doesn't work fine, because i know what i have to read and the results i get are not good. So, it reads, but it doesnt write correctly in the file.

I have to say that i proved the same code (except necessary changes) in a PC with Visual Studio 6.0 and it works fine!

CAN ANYBODY HELP ME?? Thanks a lot !

Here's the code:

I got interesting problem...
I wrote a programm, that parses a string (like CSV), but separating value is "#". This programm works ok on Asus MyPAL, Compaq, and works different on HP, it parses the string wrong... I can't understand... Please, anybody... help...

Looks like you are mixing char with wchar_t. This may work but you have to know exactly what you are doing: is the file encoded in ANSI or UNICODE? If it is an ANSI file, my approach is to read it all into a buffer and convert, to UNICODE and then parse it.

Note that the difference you are expereiencing with the different machines may be due to different levels of support of the char string functions in the different machines (my guess).

Well, i can't understand the real problem with it,
because i made this:
char* data = "Something;AND another";
char* token = strtok(data,";");
CString = token;
and i can't see the difference between this:
WCHAR * wdata = new WCHAR[strlen(data)]
MultiByteToWideChar(CP_ACP,NULL,data,strlen(data),wdata,strlen(data));
char* wtoken = wcstok(wdata,L";");
CString = wtoken;
So, can you explain, i thought that when i make char* to CString i makes the widestring by itself.
By the way i made up what you said, and now waiting the responce from the man who uses the different type of pocket - i hope it will help (what you advised me to do).
Thanks.

Hi all,

In my application using eVC++ 4.0, I have to draw ellipses with different line styles such as dashed, dotted,
dashed-dotted..

I do it in VC++ 6.0, using Bezier Functions...
But some of the functions are not supported in eVC++ 4.0.

Is there any way to draw these ellipses?

Please help me...

Thanks in Advance,

I have an IPAQ PDA and I want to write a c# code which uses a image file that must be downloaded over internet by giving the url. I tried

WebClient Client = new WebClient ();
Client.DownloadFile("http://www.xxxx.com/image.jpg", " image.jpg");

but compact framework doesn't cover WebClient class.
So how can I handle it with httpwebrequest class or any other class???
By the way, how can I just directly put it on the screen? without using memory, I mean I dont want it to be written on harddisk.

thanks...

About an ActiveX control

Hi, I'm developing a Dialog app in Visual C++. I want to add an Active Control to my project but it doesn't work. The ACtiveX control is registered in my Desktop, and I drag it to my dialog app. Then I copy the .dll and the app to my POcket PC and I execute the app and it doesn't run.

Maybe I have to register the ActiveX control in the Pocket PC? I read something about use "regsrvce.exe" for register ActiveX control but I don't find it.
How can I do it??

Thanks.
Regards.

Is there any way to use the regular controls(such as Labels & EditBoxs)

Problem getting the LBUTTONDOWN message!

Hi, I am having problem getting the LBUTTONDOWN message from the DesktopExplorerWindow.

The problem is that I cannot use any window in my application, because I wan´t to seamlessly fade from the desktop bitmap to an application bitmap using the directdraw blit for the primary surface( that is the DesktopWindow.... ).

If I create the window, during the launch of the window you can see the borders of the window coming from nowhere and then expanding to the real size of the window.

That is precisly what I don´t want to see!

I have tried to create the window without any border, specifying only the WS_VISIBLE style, but with no luck.

So, how can I get the LBUTTONDOWN message from the DesktopWindow not using any window?

Thanks, for taking your time, Dani

Well,actually the OS is wince 4.2, and all user input is coming from either the touchscreen/stylus or 4 buttons/switches.

I wan´t to redirect all the messages that goes to the desktopwindow, catch the LBUTTONDOWN message from my application and respond to it.

Then I am going to make a "fake" window by blitting to the primary surface using direct draw.

I want a message pump for my "fake "window that only catches the LBUTTONDOWN message.

The thing is that I don´t want to create any window, because when launching the window without anything on it and using no style at all produces a small box getting bigger and bigger until the window is fully expanded that is the border of the window (....and Yes it shows the border even if I have not specified that I want it, I have put the style of the window to NULL ).

I wan´t to be able to fade out the desktop window and fade in to my "fake" direct draw window seamlessly without creating any window!

The fake window is actually the primary surface which is also the desktop window.

Actually what I wan´t to do, If i explain it simple, is that I wan´t a background application (that is an application without any window) running that responds to every mouseclick send in the system.

In a PC or visual c++ this is done with a HOOK that filters the mouse messages, but in windows ce HOOK:ing with SetWindowsHookEx is not supported!

So what can I possible do, to achieve this?

Hi, I try to create a tab control for two dialogs in a dialog-based project.

In "On-initdialog" main Dialog, I do:

[code]m_pTabCtrl->Create(TCS_TABS | TCS_FIXEDWIDTH | WS_CHILD | WS_VISIBLE, CRect(0,0,100,20), this,1);[/code]
, where "m_pTabCtrl" is a pointer to a CTabCtrl member variable.

Then I want to add the 2 dialogs to this tab control, but I dont know how to do it.

Anyone can help me to complete the tab control?Do I need to add another code?

Thank you.

I want to hide the mouse cursor of my WIN CE application after a few seconds when it is not in motion.

I have created a thread and made it call the ShowCursor() for hiding and showing the cursor. But since it is called from a thread the mouse cursor is not hiding.

I have tried using both worker thread and UI thread.

When we use the funtion in normal flow of the program it works fine. Is there any othere way to achive this functionality. Plz help me.

Thanks and Regards,
