Invoking a script from PPC 2002/PPC2003 application programmatically

Hi,

I am trying to write a code in an application that would invoke functions within a script from the application in WinCE. I tried searching for examples using COM objects, but there seems to be no such object for WinCE by Microsoft. Could anybody throw some light on this please?

Thanks and Regards

Tool Bars Problem

I've got some problem with it. I try to make 2 toolbars with rebars, and when i show them all - everything is OK, but when i try to hide one of them - another toolbar doesn't repaint it self fully (just buttons that it has), and doesnt get the full avaluable area.
Here how i make them:

if (!m_wndToolBar.CreateEx(this) ||
	    !m_wndToolBar.LoadToolBar(IDR_GPS_PANEL))
	{
		TRACE0("Failed to create toolbar\n");
		return -1;      // fail to create
	}
	if (!m_wndDBToolBar.CreateEx(this) ||
	    !m_wndDBToolBar.LoadToolBar(IDR_TOOLBAR_DBLAYER))
	{
		TRACE0("Failed to create toolbar\n");
		return -1;      // fail to create
	}

	if (!m_wndReBar.Create(this) ||
	   !m_wndReBar.AddBar(&m_wndDBToolBar) ||
	   !m_wndReBar.AddBar(&m_wndToolBar))
	{
		TRACE0("Failed to create rebar\n");
		return -1;      // fail to create
	}

And It Looks Like This:
||Button1(from first toolbar)|Button2(from first toolbar)||Button1(from second toolbar
When i hide the first toolbar i have this:
||Button 1(from second toolbar)||...And this area doesnt repaint!!!
Only the Buttons on this panel are still ok...
Please help...

How do you hide/show the toolbars (what kind of functions do you use)?

Check the help file of eVC on the Data Access 3.0 or 3.1 topic. The GROUP BY clause is not supported by Pocket Access.

How do you catch the Power off

How do you programatically catch the power off button in an iPAQ 2200 Pocket PC using eMbedded Visual C++. Which event(s) should I monitor and which functions can use to check the Power Off button.
Any help is appreciated.

C# and the registry

Adrian Stanley15-Mar-04 9:06

I'm writing a Pocket PC 2003 application in C#. I have what should be a simple requirement: I want to persist applicatoin options between sessions; the most logical place seems to be in the registry, but I can't seem to find how to do it.

There's the Microsoft.Win32, but this doesn't seem to exist in the .Net Compact Framework.

There's System.Runtime.InteropServices which allow me to call Win32 APIs, e.g., RegOpenKeyEx. I've used these before in desktop apps.

The Embedded Visual C++ Version 4.0 help says "Although the registry is directly accessible, accessing the registry through the metabase is the preferred method for updating settings. This is accomplished by using the CSP specific to the settings that require an update." But I can't find any guidance on how to call CSP.

Can some one give me a clue on where to start? What is the recommended method? And perhaps some sample code.

Thanks!

This is a nice looking library, and its free. Possibly the Configuration settings namespace is more suited to my needs - saves application configuration in an XML file, presumably in the application directory. This would be much better than the global registry database, which was one of the worse ideas (IMHO) Microsoft ever had.

Thanks for the link.

Process class substitute

15-Mar-04 4:10

Hello All,

I was pointed to some code that will allow me to raise some of the settings dialogs through my application. Here is the code:

CString strParam;
strParam.Format(_T("cplmain.cpl,%d,%d"), 16, 1);

PROCESS_INFORMATION pi;
if (!::CreateProcess(_T("\\Windows\\ctlpnl.exe"),
strParam, NULL, NULL, FALSE, 0, NULL, NULL, NULL, &pi))
{
//Cannot start Control Panel process
}

So im trying to implement this in c# through the pocket pc os. I was attempting to use the Process class to create the ctlpnl.exe process, but it seems its not supported. Is there another way to implement this code easily?

Thanks,
Ryan

Alright, I've figured this out to some extent, any idea's on what im doing wrong here, because .net cf exception explanations are so detailed, lol

[System.Runtime.InteropServices.DllImport("coredll.dll")]
private static extern bool CreateProcess(string sApplicationName, string sCommandLine, long lProcessAttributes, long lThreadAttribute, long lInheritHandles, long lCreationFlags, long lEnvironment, long lCurrentDirectory, long lStartupInfo, long lProcessInformation);
private void btnTest_Click(object sender, System.EventArgs e)
{
try
{
if(CreateProcess("\\windows\\ctlpnl.exe", "cplMain.cpl,16,1", 0, 0, 0, 0, 0, 0, 0, 0))
{
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Hi friends,
Sorry for such kind of question. I am newbiee for Win CE.Is there any kind of utility available for viewing OutputDebugString output?
Like Dbgview for Winnt\98\2K

Hello Vikram,

for win CE you should use the following:

include windows.h and use following declaration...
#include <windows.h>
extern "C" void WINAPIV NKDbgPrintfW(LPCWSTR lpszFmt, ...);

use the function like:

NKDbgPrintfW (_T("%s(%i) : Warning : something went wrong here!\n"), _T(__FILE__), __LINE__);

Hope this gets you along....

If you are attached to the application (in debug mode) with the development tool, like eVC++ you can see all debug outputs in the output box of the development tool!

Okey. That is nice. But is there any kind of application like DbgView which will run on the device So that I can see these outputdebugstrings...

Re: DebugView for WinCE

Daniel Strigl15-Mar-04 20:03

Daniel Strigl

15-Mar-04 20:03

Not that I know, but you can create your own DbgView application for your device, like Paul DiLascia's TraceWin 4.0 .NET for the normal Windows OS.

Daniel.

Yes. Look at WTL 7.1: it now supports the embedded compilers (eVC3 and eVC4).

rozbeh wrote:

Please be more specific on your question.

You can find a lot of good articles here on the embedded section and also on www.pocketpcdn.com.

Clock setting screen api call

RB@Emphasys12-Mar-04 6:55

12-Mar-04 6:55

Im curious, we are developing a c# compact framework application. It is imperative that the user verify the date/time of the device before using the application. I know of the api calls to set the system date and time, but its somewhat difficult because I've only been able to find a date control for the framework. Does anyone know of a way to use an api call to bring up the standard date/time settings page in the windows ce operating system?

Thanks,
Ryan
