Does it mean that it's not possible??? And what should I use for doing it??? I've seen the ArcPad Programm where the menus are with pictures.

No, i don't have links, i had i disk with that programm it is a commercial product.
So what about the main menu in the pocket pc? I mean The "Start". We see the pictures there, or it's not a menu?

Hi all,

I have a mobile application that intended to access by cellular phone. The app is deployed in my web server and I access it using wap emulator in http://waprunner.wap3.net/emu_wap3/p/wap3/. At first the application running smoothly, but one day, I recompile the source and redeploye it, the application is not running well any more, it says there is internal server error number 500. When I try to access it using cell phone, its error too,and the message is page not found. But when I access using my browser (IE) its fine. Does any one knows how to solve it?

Hi again,
I am trying to get data from a datepicker and it gives me a CDateTimeCtrl.I think I have converted to a CTime but How do I convert that to a cString to write it to a file.

Here is what I have for code.

 <br />
CString szChoice;<br />
CTime date;<br />
m_date.GetTime(date);<br />
szChoice = date.Format(L"%x");<br />
fileRead(L"Date: " + szChoice+ " \r" )

Thanks guys,

Take a look at Strings on Pocket PC, Unicode and ANSI.

char* GetAnsiString(const CString &s, UINT nCodePage) 
{
 int nSize = s.GetLength();
 char *pAnsiString = new char[nSize+1];
 
 WideCharToMultiByte(nCodePage, 0, s, nSize+1, pAnsiString, nSize+1, NULL, NULL);
 return pAnsiString;
}
 
CString strUnicode = _T("Some test string");
char *pAnsiString = GetAnsiString(strUnicode, CP_ACP);

CTime to CString:

CString szChoice;
CTime date;
m_date.GetTime(date);
//szChoice = date.Format(L"%x");
szChoice.Format(L"%02d.%02d.%02d", date.GetDay(), date.GetMonth(), dat.GetYear());
fileRead(L"Date: " + szChoice+ L"\r");

and of course: A Date and Time formatter

printing to a text file...HELP PLEASE

rodneyk131-Mar-04 8:51

31-Mar-04 8:51

I have created an MFC app and I am using the code that you have on the web to read and write. the first problem is

1. I think from a combo box you can only read the info as a CString (is that right?)and then I pass it to the readFile method and when I do all the casting to try to get it to write the string it only prints the first letter. Can you si what I am doing wrong?

do you have suggestions?

//Get current selections from edit and list-box controls
CString szChoice;
CString szResult;
int nChoice;
m_name.GetWindowText( szChoice);
nChoice = m_name.GetCurSel();
//if(nChoice!=CB_ERR)
{
//if a valid choice was made from the list box, fetch
//the item's text string.
m_name.GetLBText(nChoice,szChoice);
szResult="Closing after selecting "+ szChoice;
fileRead(L"\\My Documents\\my_file.txt",szChoice);
}

void fileRead(TCHAR *szFileName, CString szChoice)
{

hFile = CreateFile(szFileName, GENERIC_WRITE, 0, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
//if (hFile != INVALID_HANDLE_VALUE)
{
// Note that we are writing a string, not a unicode string

LPTSTR p = szChoice.GetBuffer( 10 );//not sure if this is nessecary
wcscpy( p, L"Name: "+(szChoice)); //copying szChoice into p so I can cast(what else should I do)?

szChoice.ReleaseBuffer( );//not sure about this it was in a EVC example(What is it?)
const char *val = reinterpret_cast<const char="" *="">(p);//Casting p into a 'char' so I can print to file
//so I could try to use strcpy
AfxMessageBox (p); //gives the whole string (name:Rod) it i typed rod in combo box
strcpy(buffer2, val);//copying val into buffer 2
strcpy(buffer1, "Hello dude" );//copying string "hello dude" into buffer
WriteFile(hFile, buffer1, strlen(buffer), &dwBytesWritten, 0);//writing to file"hello dude
WriteFile(hFile, buffer2, (szChoice.GetLength()), &dwBytesWritten, 0);//*********Only writes first letter'N' I want it
//to write 'Name: Rod', what do I have to do?

CloseHandle(hFile);
}

hFile = CreateFile(L"\\My Documents\\my_file.txt", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
}

I don't get it!!!!! When I switch the order that the buffers write, say write buffer 2 first then it only writes "N" and never gets to writing buffer1, if I write the buffer1 first it writes "hello dudeN". It is like when it gets to buffer2 it stops running and will only write one charactor.

First, this is bad. GetBuffer(10) guarantees you space for atleast 10 characters (20 bytes if UNICODE is defined, 10 otherwise), but you have no idea about the upper limit. Your second line can produce a buffer overrun. A safer way to do this is:
szChoice = L"Name: " + szChoice;
LPTSTR p = szChoice.GetBuffer( 10 );
Although I wouldnt recommend it either.

rodneyk1 wrote:
const char *val = reinterpret_cast(p);//Casting p into a 'char' so I can print to file

The template argument to reinterpret_cast was lost, but Im guessing that you had char* or const char* there.

The deal is that just because you can cast a LPTSTR variable (which stands for long pointer to T string, ie wchar_t* on wince) to a const char* variable does not convert the data pointed to by said variable to char's.

rodneyk1 wrote:
strcpy(buffer2, val);//copying val into buffer 2
(I dont see where you declare buffer2, but I will assume it's declared as char buffer2[255]; )

So, here we have val (const char*), which is pointing to the same memory area as p (wchar_t*), which points to whatever memory szChoice.GetBuffer() provides (also wchar_t*).
So, if we examine the memory that val points to, it should look something like:
'N', 0, 'a', 0, 'm', ...
which means that strcpy will grab the first character and then reach the 0-terminator => strcpy appends a \0 to buffer2 and then return.

rodneyk1 wrote:
WriteFile(hFile, buffer2, (szChoice.GetLength()), &dwBytesWritten, 0);

Here, WriteFile will write 'N', 0 and then whatever garbage that buffer2 contains after the 0, until it has written szChoice.GetLength() characters. You can examine your file in a hex-editor to see what it has written, possibly all 0's after the 'N', depending on how buffer2 was declared.

In short, you should read up on WideCharToMultiByte, and also look into fixing your memory managent issues.

I have an unusual question. I am very unfamiliar with different computer codes, programming, or content type. I have received some e-mails with text that I dont quite understand. The words seems to be scrambled and don't make much sense. Is there some sort of code that I need to use to descramble it? The content type is - multipart/alternative; boundary="--69799397083396648
if that helps at all. A sample of what the text reads is "hierarchy statute proscute cacm arthur tift knit minim teakettle buttonweed" Does this make sense to anyone?

Thanks

Shell execute vs. Create Process

I'm attempting to run the ctlpnl.exe application on a pocket pc device. I want to use it to load up some of the control panel settings applets so I can have my users change the device's time ect. I have been struggling with calling the application through createprocess. Is it possible to call the shellexecute method on a pocketpc device? Any particular reason for using one over the other?

Thanks,
Ryan

I am using the ShellExecuteEx method in some of my Pocket PC applications, so it should be no problem!

For more information take a look at: QA: How can I open the default mail or browser program when the user clicks on an URL?

PS: The only nice thing about using CreateProcess is that you can wait until the running application is terminated, or for a specified timeout!

Daniel.

Problem with Virtual List View

Dear all,

I am writting a database application for Pocket PC 2002 using the eVC++ 3.0
Now, I have a problem that need to add a lot of items on the CListCtrl.

I had tried following the article found on PocketPCDN about Virtual List
View http://www.pocketpcdn.com/articles/list_view.html

but my program always displays an error message:

"Assertion Failed

Test: File
winctrl2.cpp, Line 504"

Here is my code to create the CListCtrl

if(m_wndList.Create (WS_CHILD | WS_VISIBLE | LVS_OWNERDATA | LVS_SINGLESEL |
LVS_REPORT | LVS_NOCOLUMNHEADER | LVS_NOSORTHEADER,
CRect(0,0,243,224), this, MAIN_LIST)) {

// Set List Control style to Full Row Select
DWORD dwStyle = m_wndList.GetExtendedStyle();
dwStyle |= LVS_EX_FULLROWSELECT;
m_wndList.SetExtendedStyle(dwStyle);
}

Any help is very appriciated.

Regards,
