That would be correct if I was making the change to the theme and wanted the os to update the screen. What I was looking for was how can my app tell that the os has just changed the today theme, maybe by another application or because the user when into settings->Today and changed it.

WM_WININICHANGE is fired, but it is also fired when the users add/deletes a today module. I have yet to figure out if the message was really sent because the theme was changed or something else.

The definition of the message handler that I found was OnWinIniChange(LPCTSTR lpszSection).

When I have put a break point in this handler lpszSection is always empty. For my purposes it really doesn't matter but it would be nice to not do anything in the function if the user only added a today item and not changed the theme.

João,

I saw your earlier post regarding how to change a theme programatically. I have tried using it, but it doesn't seem to work on my Dell Axim X5 or X3i.

Each time I goto Settings->Today and change the theme manually or when ThemeMaster changes the theme the WM_WININICHANGE message is sent and I can trap that just fine. This may work as a workaround for my purposes, but it would be nicer if I could just change the theme myself.

Is there a different message that is being sent by the framework to tell the os to update the theme? I have searched MSDN and I have come up with nothing. My changes are being recorded in the registry, but the theme is not changing on the screen.

Thanks,
-Eric

I sort of got it to work. Why won't it work if there is a space path to the theme? If I have a theme that has a space in its name the code won't work, however if I change the name and remove the space then it works just fine.

Try enclosing the path in double quotes.

Here is what I currently have:

<br />
TCHAR* pszFile = _T("\\Windows\\My Theme.tsk");	// The theme file<br />

If I make the filename "MyTheme.tsk" it works just fine. If I say something like "\\Storage Card\\MyTheme.tsk" it also fails.

Try this:

TCHAR* pszFile = _T("\"\\Windows\\My Theme.tsk\""); // The theme file

This works great if I am personally entering the information in as a constant into the variable. The problem is that if I read in the path from a text file I can't get it to work.

In my text file I have \Windows\My Theme.tsk

I have also tried put in my text file the above text of "\"\\Windows\\My Theme.tsk\"" and it still won't change the theme.

How can I go about ensuring that the path is formated correctly before I put it into the registry? I have even tried running thru the path and adding the extra "\" characters and the extra '"' characters and it still did not work.

Thanks for the help.

Ok,
Again the text in my text file is Today Theme=\My Documents\My Theme.tsk.

If I was going to do this without reading it in from the file I would have to format the string as such:
_T("\"\\My Documents\\My Theme.tsk\"");

Here is the code that I am using to attempt to format the string properly. I am getting the path then converting it to a CString so that I can do some other maniplutions to it.

"str" has the string value of "Today Theme" and tmp has a value of "Today Theme=\My Documents\My Theme.tsk".

I created the file on my desktop using Notepad so I am sure that the file is not Unicode and I wonder if that is having anything to do with this?

<br />
	int nCount = str.GetLength() + 1;<br />
	int nLineLength = tmp.GetLength();<br />
<br />
	//Format the line read in from the file properly.<br />
	tmp1[0] = '\\';<br />
<br />
	for(int i = nCount, j = 1; i < nLineLength; i++, j++)<br />
	{<br />
		if( tmp.GetAt(i) == '\\' )<br />
		{<br />
			tmp1[j] = '\\';<br />
			j++;<br />
		}<br />
<br />
		tmp1[j] = tmp.GetAt(i);<br />
		tmp1[j+1] = '\\';<br />
		tmp1[j+2] = NULL;<br />
	}<br />

Thanks for any insight you can provide.

This is where I would look first. Use the Notepad encoding option on File / Save As... and choose Unicode.

Has anyone successfully used the STUtil class to manage __try __Except handling in their embedded apps? I have installed it and it builds successfully, but if I try the following, my app still hangs:

__try
{
TCHAR *p=NULL;
int x = _tcslen(p);
}
__except(CATCH_COM_ERROR)
{
// handle the error
}

Souldn't the __except handler catch the error and let the app proceed?

Linker error for ConvertStringToBSTR()

Re: Linker error for ConvertStringToBSTR()

9-Nov-03 22:49

Hi all,
I'm using eVC 3.0. There is a linker error popping up when I try to convert string to BSTR. I can find its declaration under \Embedded Tools 3.0\wce300\Pocket PC 2002\atl\Include\COMUTIL.H. Which library do I have to include to get rid of the same, since COMSUPP.LIB is not supported by eVC 3.0 ?

Can I Link a checkbox to a TextBox?

12-Nov-03 2:51

My guess is that because ConvertStringToBSTR uses char* instead of TCHAR*, it is not supported under Windows CE. To achieve the same effect, take a look at _bstr_t and CComBSTR.

João Paulo

First this is what I am trying to achieve.

I want a single checkbox and a textbox. If the checkbox is checked (selected) I want the textbox to instantly become invisible or read-only. If the checkbox is un-checked I want the textbox to be visible and writable.

The environment is ASP.NET mobile controls i.e. a browser on a mobile phone, PDA, etc. Ideally I don’t want to postback when the checkbox is selected. I assume I need a SelectionList to create a checkbox but where do I go from there?

Thanks.

John.

Problem with _Connection::Open() !

nigs_krec7-Nov-03 1:54

7-Nov-03 1:54

Hi all,
I am using ADOCE. My requirement is to open a connection to a database (Test.sdf) in the Pocket PC. The problem is _Connection::Open throws an exception "File not found" even though I am giving the right path. My question is, What is the exact format format in which the connection string has to be passed to the _Connection::Open() function ?
Any help would be appreciated.
Regards,
Amit

João Paulo Figueira7-Nov-03 2:30

From the adoce31.tlh file (generated using the #import directive, we can read the method prototype as:

HRESULT Open (
    _bstr_t ConnectionString,
    _bstr_t UserID,
    _bstr_t Password,
    long Options );

All parameters are optional. The ConnectionString parameter states the connection string(that can be optionally set via PutConnectionString) has a very specific format. For "Pocket Access" databases, use Data Source=\\FolderName\\DbName.cdb. Top open SQL CE databases, use:

_Connection::PutProvider(_T("Microsoft.SQLSERVER.OLEDB.CE.2.0"));
_Connection::Open(_T("Data Source=\\FolderName\\DbName.cdb"));

You can optionally do everything in one step:

Open(_T("Provider=Microsoft.SQLSERVER.OLEDB.CE.2.0;Data Source=\\FolderName\\DbName.cdb"));

João Paulo

Hi,
I am giving the connection string as "Data Source = history.sdf" but still the same problem persists. Could this be because this format is only applicable for *.cdb file and not *.sdf ? I am having Test.sdf on my pocket PC as the query analyzer gave only one option (SDF) while creating the database.
Many thanks for your reply.
Regards,
Amit

Use a full path name on the connection string. The Pocket PC does not allow for relative path names, nor does it recognize a current directory. Check my samples: they all start with a '\'.

João Paulo

nigs_krec7-Nov-03 3:13

7-Nov-03 3:13

Hi there João,
I have tried giving "Data Source = \\history.sdf" and have ensured that this file is present in the root directory (listed as "My Device" as seen from the file explorer in the pocket PC). Still the same problem persists. Could there be any thing else I can try ?
Regards,
Amit

João Paulo Figueira7-Nov-03 3:19

If you did set the correct provider, I can only guess that the file is corrupted. Use the SQL CE query analyzer to open the database file and browse it.

João Paulo
