I don't know about C#, but in C/C++ you can use WM_COPYDATA.

I'm thinking of automatically configure the 802.11 wireless network without use the standard windows wizard.
Can any expert tell me which kind of steps and APIs I should use to achieve this object.
Thanks

I'm doing Embedded Development using Visual C#, VS.NET 2003 & PPC 2003 SE Emulator. I have a TextBox Control and I want to change the BackColor of it when someone clicks on it. Apparently Windows Forms Designer doesn't have the Click Event on the list of events available on the Windows Forms Designer but you can generate it from within the Code Editor. The Code Editor gives you the "Click" property when you type "." after the TextBox's name and then, after you type "+=" it detects that you want to generate an event handler displays a tooltip suggesting the rest of the line as in "new EventHandler(textBoxSearch_Click); (Press TAB to insert)". When you do press TAB it generates the new "EventHandler..." line and highlights "textBoxSearch_Click" and gives you another "(Press TAB to insert)" tooltip which will generate the "textBoxSearch_Click" handler in the current Form class. I put my code in the handler but nothing happens when I click on it. I ran it through the debugger putting a breakpoint inside the handler and nothing at all!! The program behaves as if there is no click event handler on the TextBox. Note that all the other event handlers for my other controls on the form work fine. But those other event handlers where generated through the Windows Forms Designer. Any suggestions?? Ideas??
TIA

HI~
In WinCE (pocket pc), how to set a window to scrollable in vertical and honzontal direction?
Thanks
|
|
|
|
|
I'd like to manage my Pocket PC from Desktop computer. For example to create file, or to delete it from Pocket PC. What should i use? Sockets? Or may be i can work with pocket pc like with a disket or any other driver by using the api functions like (CreateFile, DeleteFile)?
|
|

|

Yes, you can use RAPI (Remote Application Programming Interface wich have all the functions like CeReadFile, CeCreateFile, ...
Take a look at the MSDN for complete documentation.

This works the other way: from within a program on your desktop computer you can delete or create files on your PocketPC. Not the other way.
Hope this helps

when i am writing few assembly language programs, after assembling i found .lnk and .obj files.
what the .lnk files hold and how they r built?. why there is change in opcodes of the instructions?.
Example for Mov 70h,#29h the opcode there is 757029
but for mov r1,#20h. it is giving some other opcodes.
why there is a change in this?.

Hi,
I am more of an embedded programmer so I this may not be correct for your situation but this is my experience from the past.
'.lnk' files are normally link files, they tell the linker how to join (link) different modules of code, in the old days programmers wrote their own link files, but it is often done by the programming environment now.
'.obj' files are object files, they are intermediate files generated from the aseembler prior to being linked together to form the final program.
Op Code
From your example 'Mov 70h,#29h', 75 will be the 'op code' for the instruction 'Mov', the source & destination are added to the end of it ie 75,70,29 = 757029
So the result for 'mov r1,#20h' will be 75,??,20 where ?? = the address (index) of r1.
Hope this helps a bit.

To all Gurus,
How can I get a handle to the window of item on the toay screen.
I want to refresh a today screen. But this refresh is NOT triggerred by any user input like a Tap etc but from within a DLL.
Can I send a message to the window ? but in that case I would need a handle to the window.
I know the Class Name and Window Name so how can I post a message to the window to refresh?
any kind of Help will be highly appreciated.

FindWindow returns a handle to a window if you know the class name and window name
HWND FindWindow(
LPCTSTR lpClassName,
LPCTSTR lpWindowName
);
Friendly regards

GDvay,
Thanks a lot lof replying.
I had tried that (did not work) , There is a problem with find window.
FindWindow doesn't seem to work for The items on the today screen.
I am not sure but it could be because the items on the today screen are child windows and findWindow returns only parent windows. I am not sure whats the parent window.
Have you tried this before ? Do you know of any work around.
I am at a dead stop here.

Hi, i need to upload about 500 .jpg files to my pocket to be use by my application. Is there a way to compressed such files to lessen memory use, thanks   
|

|

jpeg is already a compressed format, all you can do is increase the compression factor (resulting in lower picture quality of course).

Dear Experts,
I am a novice student programmer who is touching Embedded Visual C++ for the first time in my life. (Previously only learnt BASIC and Visual Basic).
Currently, I am involved in this project to this simple pda to pda wireless communication. I am currently stuck at the server side of the communication program. (The client program has been written and tested to be working well).
The problem with the server side is that the program does not seems to execute the OnAccept function of the Listening socket(
although it jolly well could create a socket, listen for connection and seems to make the client program aware of its presence
by enable the client able to establish connection with the server whenever the client is attempting to connect the same port
that the socket is listening to). By not doing so, I am unable to create another client socket for communication. (Came to this
conclusion as neither results I have put in the function has appear when excuted)
I have declared the following Classes:
CServerApp (By default generated)
CServerDlg (By default generated)
CListenSocket (Class for the listening scoket. Base class: CSocket)
CLinkSocket (Class for the Client scoket. Base class: CSocket)
Member Variables (Only for the class CServerDlg, the rest does not have any)
IDC_cmdListen
Function: Listen for connection
Type: CButton
Member: m_bListen
IDC_cmdDisConnect
Function: Disconnect current connection
Type: CButton
Member: m_bDisconnect
IDC_cmdStop
Function: Stop all server service
Type: CButton
Member: m_bStop
IDC_Port
Function: hold the value of the port name
Type: int
Member: m_sPort
IDC_Status
Function: hold the value of the text meant for a status screen
Type: CString
Member: m_sStatus

I have realised what is the root of my problem: I am somehow unable to override my clistensocket::onaccept function. I have tried the solution u have posted and my own method of transfering the clistensocket::onaccept function to the main dialog classes but still I am unable to override my function. So, can any experts point why did I go wrong?

Hi all,
I am currently developing a PocketPC application using SqlCe2.0 and Evc++ 3.0. I am using SSCEOLEDB.
I saw the following thread in google
http://groups.google.co.in/groups?q=memory+leaks+in++ssceoledb&hl=en&lr=&ie=UTF-8&selm=078301c33c6c%24de966a80%24a301280a%40phx.gbl&rnum=1
regarding the memory leaks in SqlCe2.0 and EVC++ 3.0.
I am into the same problem now.
Memory leaks occurs every time i execute ICommandText->Execute() method.
I heard that memory leak occurs due to ICommandText->Execute() when we use Oledb for oracle. Does the same problem occurs in SqlCe2.0?
Kindly send your suggestions.

Greetings to all,
I am in need of some sample code or documentation (something, ANYTHING) to get me started. I've just been thrown into the CE development arena and need to write an Owner Drawn ListBox Control that will run under CE. It needs to display different fonts, fontcolor, and background colors on a line by line basis. I've not worked with CE and need a place to start. Any suggestions would be appreciated.

No freakin' way...  (no OS support)
Use the list view control instead:  one column and a custom draw bonanza to fill in your wildest dreams (and there are lots of articles here on CP too).
But if you really really really must use a list box, try these general principles (good luck - it's not easy  ):
QA: How do I create a combo box with check marks?[^]
