Are you shure that the thread started correctly? Just show a message box when the thread is started.
Just try to read some data from the COM outside of the thread, to see if the serial communication work!

PS: I use the Serial library for C++ library (with some little changes that it will compile under eVC++) for my serial communication!

Daniel.

opening and accessing and changing a database

Hi All,
I am new to the EVC world and have writen som e simple projects that work fine, but now I would like to get them to manipulate databases and have searched through the past listings and can't find what I need.

First how do I get a program to OPEN and access the data base, what do I need to #include for the operations.

I would love a simple sample of code that uses a datadase to get started.

Second once I access the file how do I change things inside it. How do I save things to the file? Can I use the Database functions for CE, Like "CECreateDatabaseEX" or is this not going to be recognized by EVC++ 3.0.

Thanks for all the help Smile | :)

I assume you want to use the CE DB provider, is this correct?

Add image to ColumnHeader in .Net Compact Framework

Does anyone know how to add an image to the ColumnHeader control in the .Net Compact Framework?

The Microsoft Windows CE .NET 4.2 documentation has an article "Working with Advanced Header Control Features" which describes how you can do this non .Net code, so it should be possible in .Net too; has any one got this working, or do I need to write my own code?

Thanks.

Try downloading a font with Russian characters to the \Windows\Fonts folder and use it. It can be one that you have on your desktop.

Sorry, I'm newbie Blush | :O

I have to use ISA bus under my own Windows CE OS.
I found lots of information about CEDDK on the MSDN site.

I also found this code which can help me, I hope: http://www.odints.com/pages/support/drivers/thor/thormain.htm

Does someone have already had to use ISA bus under a eVC program?
Can you give me informations or codes? ;o)

Do you think, the code I had found could help me?

Is it better to develop dll or driver in this case?

Thank you for your help!

Sorry for my poor English.

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

Rassul Yunussov15-Mar-04 22:32

15-Mar-04 22:32

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...

Dear all,

I 've been trying to query database (Pocket Access) using GROUP BY in SQL command but it returns fail.

I wonder does ADOCE support GROUP BY in SQL command?

Thanks in advance.

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 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

Adrian Stanley

15-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.
