I developed a small app for my PDA with EVC++3. It runs perfectly on my PocketPC, which runs on PPC 3.0 (that what "info" says, it is usually called PocketPC 2002, right?).
Now i wonder if I can run this programm on another PDA that runs on PPC 4.2 (that's called PocketPC 2003, right?).
Is that possible??
I copied the .exe on the PPC03 and i could even start it. however, my app reads pictures from files and those were not shown on PPC03 while there were no problems on PPC02.
Then I wanted to change some code and let EVC++ copy the programm on the PPC02. This wasn't possible (Platform Manager problems).
Would this be possible at all?
thx, Daniel

The answer to the first question is yes: you can run on a Pocket PC 2003 application that were developed for the Pocket PC 2002.
As for the second question, everything should be working correctly, unless you are using an API that behaves differently (!?!?). How are you loading the images?

I AM using some APIs and Libs and those are probably the reason, but I have no idea what to do.
I read html-files and jpg-files and display HTML on the screen.
I use
- ReadFile() to read the html-file,
- VOImage to read the jpg-files (http://www.pocketpcdn.com/libraries/voimage.html / http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppc2k/html/ppc_viewer.asp ), and
- CSTHtmlDialog to show the HTML (http://www.codeproject.com/ce/sthtmldialog.asp).
Do I need to copy or register anything on the PPC Device? For PPC02 I always used EVC to upload my app to the device, but on PPC03 I had to copy the .exe manually. Is that the problem?
(By the way: If I copy the exe out of ARMDbg instead of ARMRel, my app won't even start on the device).
What is also strange: If I start the app and a HTML-page with some images is shown, the images are shown for about 0.1 secs and then they are replaced by the typical red [x] symbol.
??
thx, Daniel

I added WM_CLOSE handler via class wizard in CMainFrame. It deleted other two afx_msg handlers from mainframe.h
Although I pasted the two handlers declarations again, just wondering what is the reason behind this...
Any ideas?

What handlers did it delete?

Hi,
I have a problem with the AppWizard-generated code of eVC4 and I have no idea what's wrong with it. Any help is appreciated.
I generate a new application "Test" with the AppWizard:
- Single document with DocList
- Windows Sockets, ActiveX Controls and Shared New disabled
- Basic MenuBar
- Source File Comments enabled
- Statically linked MFC Library
- Base class "CFormView" for my view class "CTestView"
After building the project I run the application. Now I would expect my view to show the contents of the associated dialog ressource (some static content generated by AppWizard like "TODO: Add controls"). But the only thing I get is a white, empty window.
What am I supposed to do?
(You can find the files at http://www.ralf-limbacher.de/eVC4/Test.zip.)
Thanks in advance
Ralf

I just have a XML document which is generated by my ASP script.
Now I want to download it and tranform it to the PDB format.
It must be done absolutely automatic by my ASP script from download to transform.
Now I have a problem,how can I tranform it from the XML format(it is just like a plain txt) to the PDB format.
I'm a freshman in this area.I used to refer to this page
http://www.palmos.com/dev/support/docs/fileformats/front.html
for the information of the PDB format.
All I know is the PDB format have a PDB header and the list of the records' entry.
Please help me,every tips will be appreciated.

Hello !
I have a really strange problem:
I write a string to a file:
<br />
FILE* pFile = fopen("profile.tmp","w");<br />
....<br />
...<br />
...<br />
char Buff[256];<br />
sprintf(Buff,"\n[%s]\n",mainkey);<br />
fputs(Buff,newfile);<br />
The instruction fputs fire an exception: "First chance excepetion: access violation" 
I checked the string, it's perfectly correct and the file handle is valid. I cannot find any solution to this problem !!
Please give me some clues.... 
Thanks

What is the platform?

Does the value of mainkey fit into the buffer?
By the way, why are you using ASCII text instead of Unicode?
Regards,
João Paulo
|
|

|

Yes everything is correct.
I use ASCII instead of unicode because it has to be compatible with my library that has been developped for the desktop computer. I cannot write everything again.
But the bug is solvedf but I don't have an explanation. I was using _wfopen instead of fopen (with TCHAR string). So I changed it and now that works

Hello !
Has anyone here yet ventured into the world of Symbian or Series 60 development ? What tools do you use ? As far as I know, the Series 60 SDK and it's tools are a piece of crap: a bunch of script-driven gcc-tools.
I've heard about the Borland Mobile Studio but it doesn't seem to be available for purchase yet.. Is it even released yet ?
Any other options you would recommend ? I do have the Visual Studio solution already with the script-driven tools, but like I said, they are an abomination to application development: even a crude Unix hack looks smoother than this package..

They look worse when you start using them. After a while... Well, integration is not their forte...
The tools are a bit crude, as you say. But if you look under the covers you will find some gems thet will make your life less miserable. Anyway, it's a sizeable learning curve...
Good luck!

Hello !
This may be a stupid question, but how can I reinstall my PocketPC (like formating it...) ?
I need to know exactly wich ressources I need for my applications to run and so I must start on a 'new' Pocket PC.
Thanks

You can't, but what you can do is clear the memory.
Look up 'hard reset' or 'cold reset' in the device's manual. If you really can't find it, try doing it in code[^].

hello,
I need to use the function CoCreateFreeThreadedMarshaler in my Application for Pocket PC 2003 (eVC++ 4.0) but despite the MSDN site mentionned that ole32.lib exports it since winCE 3.0, this function not appears in my ole32 (SDK for PPC).
So anyone has an idea of what I can do with it ?

Hi All,
Are there any free printer libraries for Windows CE?

You could try the HP mobile printing SDK:

I can't find any samples (beyond Hello World). I have been able to do a few very basic things, but cannot get to the registry, messaging, etc.
Does anyone have any working code that would give me a basic starting point?
thanks

Hi,
I'm programming with eVC++ 4 and have the following problem:
My program should use an INI file to read and write several values. To read/write I will use the functions GetProfileString and WriteProfileString (class CWinApp). But each call of this functions failed.
I use the following code (exactly like MSDN and eVC++ helpfile) :
BOOL CMyApp::InitInstance()
{
free((void*) m_pszProfileName );
m_pszProfileName = _tcsdup(_T("/Temp/COMConn.ini"));
...
}
void CDlgClass::ReadIniFile()
{
CString csValue;
...
AfxGetApp()->WriteProfileString(_T("Connect"), // Section
_T("Name"), // Key
_T("MyConnect") ); // Value to write
csValue = AfxGetApp()->GetProfileString(_T("Connect"), // Section
_T("Name"), // Key
_T("Error") ); // Default
...
}
The ini file /Temp/COMConn.ini exists, but each call of WriteProfileString() returns FALSE and each call of GetProfileString() returns "Error".
Why failed every access ?
Please help me (fast).
Thank You
Rico

These methods only work with the registry. To use an ini file, you will have to roll your own (like I did).
