Hi all,
I p/Invoke a VC++ dll in C#, but there is serious memory leak, how can I fix the memory leakage by the VC++ dll caused by P/Invoke ?
(the leakage seem not come from the internal C++ code inside the dll, so I suspect it come from the loading and unloading of the dll in C#)
Thanks

I found this example on how to program a software input panel (SIP) at this site.[^] I have eVC++ and all the service packs. My goal is to try and modify the SIP provided off of the site, but my biggest problem is i can't get it running in the first place. I can compile the code, but i can't get the SIP to work on the emulator or on My Axim X50v. If someone could tell me how to get it working i would really appriciate it.
I understand form his site that i have to change the registry to get be able to use the SIP, but the registry value is never placed on my PDA or i don't know what to copy to where.
thanks

Hi,
I am currently writing an application in pocket pc 2003. The application
need to get those emails related to the application(e.g. email from a specified contact) from the default email client in pocketpc and store them in the application. But I face a design consideration problem,
1. Are most users use the default email client in pocket pc when they
receive email wirelessly ? If not, my application need to connect to the other third-party email client also, but how I program the application to connect to diverse set of pocket pc email clients available on the market ? Are there a common standard for doing this ?
2. My application need to send email from the pocket pc, the current
method is to send the email message to the default email client in the pocket pc, and the user click the send/receive button on the default client later. But this seem not quite user-friendly to the users. Original, I intend to write code so that the application directly send email to the smtp server, but the coding seem quite complex and need to handle many cases for the smtp server protocol handshaking. So are there any better methods ?
Thanks

A rather tricky question: Is is possible to design a program to lay on top of two other programs in order to be able to control the audio from these 2 programs. I want to be able to mute the first programs audio so that the other can use the speaker, and the unmute so that the first program uses the speaker. Does anyone know if this is possible? If so, could someone provide me with sample code for VB.net?
Best regards
Mikkel

Hi all, i'm currently working on a school project and are very new in this.
The code below is something i had modify:
BOOL CCheckBookFile::New()
{
CString strFilter;
CString allFilter;
CString strTitle;
CString OpenFilter;
OpenFilter ="Text File (*.txt)|*.txt|";
OpenFilter += "RTF (*.rtf)|*.rtf|";
OpenFilter += "ASC (*.asc)|*.asc|";
OpenFilter += "Word Document (*.doc)|*.doc|";
OpenFilter += "All Files (*.*)|*.*||";
CFileDialog dlg(FALSE, NULL, TEXT("\\My Documents\\NewFile"), OFN_FILEMUSTEXIST | OFN_OVERWRITEPROMPT | OFN_HIDEREADONLY | OFN_PATHMUSTEXIST, OpenFilter, NULL);
strTitle.LoadString(IDS_FILE_NEW);
dlg.m_ofn.lpstrTitle = strTitle;
if (dlg.DoModal() == IDCANCEL)
return FALSE;
if (m_file.m_hFile != (UINT)CFile::hFileNull)
m_file.Close();
if (!m_file.Open(dlg.GetPathName(), CFile::modeCreate | CFile::modeReadWrite | CFile::modeNoTruncate | CFile::typeText ))
{
AfxMessageBox(CString((LPCTSTR)IDS_MESSAGE5));
// Call open again
if (!New())
return FALSE;
else
return TRUE;
}
return TRUE;
}
well, there are 184kb in the save file, and it's in .txt format.
but when i open it, it will show some strange words.
But when i use my program to open it, it seems fine.
Does anyone know how to change it to a readable .txt file?
Thanks
And by the way, i'm using pocket word to open the .txt files that i had saved.

It sounds to me like you are having a problem converting between unicode and ascii. All strings in wince are unicode (ie 2 bytes per character) whereas strings on a normal pc are ascii (1 byte per character). It looks like your program is writing and reading directly from windows ce strings which means your text file is probably in unicode, and pocket word is probably trying to open them in ascii format.
You can check this out by using a program like ultraedit to view the file and see if it is indeed in unicode or ascii.
Kind Regards

hi hterry61, thank you for the reply 
I'm using Embedded C++ ver3.0 and running on an emulator.
Can i install the "ultraedit" in it?
And if say i want it to save to .txt format, so that it can be open in pocket words, do i have to change it to unicode? If so, how can i change the codings?thank you

if i want to open the saved file in pocket word, do i have to save it in ascii format in order to view the files?
I can view properly in my program, but got funny wordings when open in pocket words.
thanks

Put this trial software on your computer, transfer your "text" file to your pc and try to open it. Right click on the file that opened and go to "Hex Edit". This will show you exactly what is happening. My suspicion is that you will be getting 00 xx 00 xx 00 xx. This is because the first byte of every unicode will be 00 as it only requires the second byte for your ascii characters.
What you need to do is get your program writing and reading so that your data is xx xx xx instead.
If your "text" file is already writing as xx xx xx, then it is the reverse problem that you have.
There are plenty of resources on the web to show you how to do this.
for example:
http://www.developer.com/net/net/print.php/3304241
Good Luck!

Hi all,
I am wondering how to get a CCeSocket working properly from a separate user-interface thread. The trouble I am having is that if I use the CCeSocket::Send(pData, nSize) command in the main thread, I can send things fine, but since it is a blocking call I lose control of my GUI wile it is sending.
I instead call this from a second user-interface thread that I have running in the background, but it ALWAYS stops at 16384 bytes (16K). It is like it is waiting for some message from the server that it never receives. (Coincidentally, the same thing happens if you use CAsyncSocket::Send(pData, nSize) on my CE platform)
My thought is that the CCeSocket Monitoring thread is sending messages to the main thread instead of my second user-interface thread. Any thoughts on how I can fix this?
Thanks
Terry

1. Try insert Sleep(300) somewhere in the code before you call the function. It usually help.
2. Don't forget to use critical section, multithreaded application is a tricky business.

Hi,
could anyone please help me, how to pass command line argument to my app?
my code is as follows:
<br />
#include "stdafx.h"<br />
<br />
int WINAPI WinMain(HINSTANCE hInstance,<br />
HINSTANCE hPrevInstance,<br />
LPTSTR lpCmdLine,<br />
int nCmdShow)<br />
<br />
{<br />
if (*lpCmdLine == 'test'){<br />
MessageBox(NULL, TEXT("OK"), TEXT("Result"), MB_OK);<br />
}<br />
else {<br />
MessageBox(NULL, TEXT("NotOK"), TEXT("Result"), MB_OK);<br />
}<br />
<br />
return 0;<br />
}<br />
The problem is, that it always goes to "else"...
Thank You
Martin

Use
if(wcscmp(lpCmdLine, _T("test")) == 0)
for the comparison test.

As you can imagine, I'm a beginner at programming Pocket PC's, and I need some help.
I want to "draw" the contents of a DATETIMEPICKER, at the Today Screen. I tried the following:
DateTime_SetFormat( GetDlgItem(hDlg,IDC_DATETIMEPICKER1 ), TEXT("dd MM yyyy"));<br />
DateTime_GetSystemtime( GetDlgItem(hDlg,IDC_DATETIMEPICKER1 ),&stDate);<br />
GetDateFormat(LOCALE_USER_DEFAULT, DATE_SHORTDATE, &stDate, TEXT("dd MM yyyy"), date, 10);<br />
<br />
DrawText(hdc,date,10,&rcClient,DT_CENTER);
But it doesn't work.
I also tried with ExtTextOut, without any success.
I thank you all for taking the time to help me.

Hi,
I want to know how to communicate 700 series hand held intermec pc with 6920 communication server. I've 6920 communication server installed on my desktop pc. But I am pretty confused about client part on my hand held device. I don't know which client software to use.
So if anybody can provide me the exact steps for communication between pocket pc (700 series intermac OS: WinCE) & 6920 norand communication server, then it would be immensely helpful to me...
Thank you..

:|I am loading a 4X5 picturebox matrix using a bitmap file template. As each cell in the matrix is being loaded, I append a text string using the DrawString function to complete the cell's image.
The problem is that the DrawString function seems to work only on the desktop and not on the hx4700.
Does any body know how to get around the DrawString to draw a string on a bitmap image at runtime?
This will avoid having to crate separate images for each cell on the matrix.
Thanks for the help!

Hi,
I run down all the controls in my CDialog using
CWnd *hWnd = GetWindow(GW_CHILD);
anyone knows a way to retrieve the kind of control (I mean: if it's a CButton, CEdit... or even if it's a PUSHBUTTON, COMBOBOX ... and so on..) on my Dialog?
I tried using
CString str;
CRuntimeClass *prt;
prt=hWnd->GetRuntimeClass();
str=prt->m_lpszClassName;
but str always takes the value "CWnd".
I tried putting /GR compiler flag inside Project Options but the compiler complaint... Is there another way to do it? where am I wrong?
[environment: WinCE, pocketpc2003]

Use GetClassName API function to retrieve the HWND class name.

Simple question - does anyone know what the block size of the filesystem on a storage card on an MS Smartphone is? Is it even system defined, or is it likely to vary depending on the device or storage card being used?
I'm basically developing a PC app that copies files to a Smartphone using RAPI, but am having problems as the size a file occupies, and its reported size are never the same (due to the block size)
I'm using OpenNETCF.Desktop.Communications for the RAPI work, and have been unable to find any way of either reading the actual free space on the device, or any kind of information about the filesystem.

Hello all,
This is my 1st post a a member for a few months now.. Love the site...
OK.. I am trying to execute other applications (user has check boxes to select the function) on the PPC via the following:
CreateProcess(@"\windows\fexplore.exe",@"myPathAndExeHere",... other args...);
Note I am utilising:
[DllImport("CoreDll.dll")] to get CreateProcess.
It works really well, except that fexplore process remains running, even though the app I called has finished...
I can't proceed to any other apps I want to call, until fexplore is finished...
SO... what I am thinking I need to do is somehow scan to see if "File Explorer" is running {somehow} and "Stop" that/those process(es)..
Could anyone give me any insights?
Will be <GREATLY> appreciated.
TIA
