Is there a way to display Pocket excel/ Excel from my application without using the Shellexecute, like you can display Pocket Word files from the program on a pocket pc using the richink control, is there something similar for Excel/Pocket Excel as well.

I will be using evc ++ 3.0, Win32, 2002/2003

speech-enabled aps.net pages

Hi, everyone! Forgive my ignorance if i shouldn't post this here.

I've downloaded speech sdk .net and it works great with asp.net pages, but i don't know if it is possible to make speech-enabled mobile asp.net page???

When i try to add speech control on the MobileWebForm, VS tells me that i have to delete the control or put it inside a template. At the moment, i'm reading a book about templates in asp.net.

Since i'm reading it for only one reason (to speech-enable my asp.net app), please tell am i going the right way?

Thank You!

p.s.: msdn says that we can speech-enable web apps - seems like i am the only one to be in dark Wink | ;)

SD Card corruption

Hi,
My application takes and writes data on to the sd card often. I am experiencing a lot of SD Card corruption cases. I have fixed every possible loophole as such, but have no idea as to what causes this SD card to be corrupt

Any ideas?
What all scenarios cause sd card to be corrupt?

Eventually SD card's cannot retain new writes. But this is after a very large number of writes. If you were reading and writing to the SD card continuosly I suppose you could have reached that point. Have to tried reading and writing to the device's memory instead of the SD card to confirm that it is indeed a problem with the SD card. Do you have another SD card you could try? Or another device you could test the card on?

Thanks,
I did not know that eventually SD cards would crash. Any document or more info about that.
My application writes to a log file in SD Card as long as it runs.It logs every event and method of the app being called by the user. Infact everything that my app needs like the database, the text files to read data from and write data into, log files etc all of them are in SD Card. This application runs around 1 or 2 days or so then somehow somewhere SD Card gets corrupt.The corruption is very sporadic.So not able to replicate..

Is there some max number after which the SD Card cannot write and just crashes. I have tried with a couple of SD Cards, and all of them exhibit the same kind of behaviour. But not due a specific operation in the application but just random operation.

Thanks in advance...

Can't debug using emulator

Visual Studio 2003
PocketPC 2003 SDK

When I try to debug, emulator starts, everything loads into it, and the program is downloaded. I can go to the emulator and run the program. But Visual Studio does not go into debug mode so I can set breakpoints, look at things, etc.

Any suggestions?

Thank you

If you're using MFC, you can use the MFC Grid control [^] developped by Chris Maunder. It's realy complete...

GetProcAddress fails, whats wrong?

I'm doing a dll on my pocketpc and it fails when I try to get a function pointer from it.

I have this in the dll code:

__declspec (dllexport) void InitFunc (void);
void InitFunc (void)
{
...
}

And this is how I load the dll in the main program:

HINSTANCE hDll;
FARPROC dllInitFunc;
void LoadLib (void)
{
DWORD err;

hDll=LoadLibrary(L"mylib.dll");
if (hDll==NULL){
MessageBox(hWnd,L"Failed to load dll",L"Error",MB_OK);
return;
}
dllInitFunc=GetProcAddress(hVibradll,L"InitFunc");
if (dllInitFunc==NULL){
err=GetLastError();
MessageBox(hWnd,L"Failed to get proc address",L"Error",MB_OK);
}
}

dllInitFunc becomes NULL and err is 87, ERROR_INVALID_PARAMETER.

What am I doing wrong?

The problem is this:
I wish to create a folder inside the 'My Documents' folder.
I am fairly sure that it must be done via MAPI but all the documentation I have found relates to using messages such as email, SMS, etc.
I have initialized COM and MAPI and have opened a session with MAPILogonEx() but from here I'm stumped.
How do I access the IMAPIFolder interface from my session pointer?

Back color of a static text

Hello !

I have a SDI app (view derived from CFormView) in wich I repainted the background in grey (instead of white). I have a static text on it and of course the background color is white...
I want to color it in grey. Who can I do it? Can I send a message to the control or do I need to subclass the control ?

Thanks

Write a handler for OnCtlColor (MFC). You will be able to specify the device context's colors (text and background).

First Chance Exception

In Windows CE.NET 4.2, when I Call the CMyPropSheet::DoModal(), it cause an exception at the function call as below:
int CPropertySheet::DoModal()
{
...
==> HWND hWnd = (HWND)::PropertySheet((AFX_OLDPROPSHEETHEADER*)psh);
...
};
The description as below is copy from the online help of CPropertySheet member function DoModal:
{

The first time a property page is created from its corresponding dialog resource, it may cause a first-chance exception. This is a result of the property page changing the style of the dialog resource to the required style prior to creating the page. Because resources are generally read-only, this causes an exception. The exception is handled by the system, and a copy of the modified resource is made automatically by the system. The first-chance exception can thus be ignored.

}
but the system seem did not handle this exception, this would never happen in Windows CE.NET 4.1.
I need somebody to help me to solve this problem, thanks in advance!
