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" Dead | X|

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.... Smile | :)

Thanks

Does the value of mainkey fit into the buffer?

By the way, why are you using ASCII text instead of Unicode?

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 Confused | :confused:

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.. Smile | :)

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!

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[^].

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?

Read/write INI files with eVC++4

Rico Salfer26-Jan-04 4:52

Rico Salfer

26-Jan-04 4:52

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).

Hi ,

On the PDA's calendar, I want to add a new item in the menu(when I hold the Stylus for a brief time).

Where can I found its entry in the registry? Or is there any other way with which I can achieve this?

Check the online help file under Extending Pocket Outlook Menus.

Quote:
The Calendar, Tasks, and Contacts applications support menu add-ins for external applications. If you provide an add-in for one of these applications, your menu item appears on the Tools menu. When the user selects your menu item, Pocket Outlook calls a function in a registered DLL, which passes the object identifiers of the currently selected items in the application.

To register your application, create a registry key under the following key:

Software\Microsoft\PimApps\PimExtensions\pim_app\AddIns

You can use any name that you want for the key. To avoid conflicts with other add-ins, we suggest that the key contain the name of your company. Replace pim_app with Contacts, Tasks, or Calendar, depending on which application’s menu you want your add-in to appear on.

After you create this key, you need to create two values for the key. The first value is DLL, which you set to the name of your DLL. The second value is Menu, which you set to the name that you want displayed on the Tools menu. Others may add tools items, so you should try to create a unique, descriptive, and mnemonic name that will distinguish your application.

For example, the following registry key would register a phone-dialer application in the Contacts application:

Software\Microsoft\PimApps\PimExtensions\Contacts\AddIns\MicrosoftDialer<br />
DLL: dialer.dll<br />
Menu: "Dial Contact"

The registered DLL must expose the CePimCommand function, which is called automatically when the user chooses the menu command.

João Paulo

A question about displays

For Pocket PC 2003, look under Adding Menu Commands for External Applications.

Quote:
The Calendar, Tasks, and Contacts applications support menu add-ins for external applications. If you provide an add-in to one of these applications, your command will appear on the Tools menu. When the user selects your command, a function in a registered DLL will be called, passing in the object identifiers of items that were selected in the application at the time the menu item was selected.

To register your application, you need to create a registry key under the HKEY_LOCAL_MACHINE root. To avoid conflicting with other add-ins, it is suggested that the key you choose contain your company's name. PIMAPP should be replaced with Contacts, Tasks, or Calendar depending on which application you want your menu to appear in.

To create a menu add-in

Register your application by creating a registry. The registry will exist in the following key, and can be named whatever you want:
HKEY_LOCAL_MACHINE\Software\Microsoft\PimApps\PimExtensions\PIMAPP\AddIns

Create an entry under this key, DLL, where the value of the entry is the name of your DLL.
Create a second entry, Menu, in which the value of the entry is the menu name you want displayed from the Tools menu.
The DLL that you register must expose the CePimCommand function, which will be called when the user selects your command. The following code sample shows the exposed function:

void CePimCommand (HWND hWnd, PIMTYPE ptData, UINT uDataCount,
 *rghData, void *pReserved);

PIMTYPE is an enumeration, defined as follows:

typedef enum tagPIMTYPE
{
 PT_CALENDAR = 0,
 PT_TASKS,
 PT_CONTACT
} PIMTYPE;

The following table shows parameters associated with the CePimCommand function.

Parameter Comments
HWND hWnd Application window handle
PIMTYPE ptData The application that is calling this function
UINT uDataCount The number of items in the array rghData
HANDLE *rghData An array of Microsoft Windows CE object identifiers indicating which items are currently selected
void *pReserved Reserved parameter

You can manipulate items from their object identifiers by calling the GetItemFromOid method in the Application object. You can use GetOidFromRef for menu extensibility.

João Paulo

Another noob question, I'm afraid.

What's the typical color depth of a PPC 2002 or 2003 PDA or Smartphone display ? I'm curious - I don't have access to hardware, just the emulator, and I'm wondering how to handle graphics code.
