Did XP sp2 change something in the EVC4 arena?

I've just inherited a project that needs to compile in both EVC3 and EVC4. I've not had a problem with EVC3 at all. I'm pretty sure that I was able to get it to compile in EVC4 at one point right after I got the project.

Today, I've installed SP2 and now I get compile errors on SHRGINFO and related things. The PDA that I was given to work with this is PPC2002, so I'm not totally sure that SP2 is the problem.

Anyone else experience problems after SP2?

Thanks,
Mike

yep, i cant install eVC4 on my XP-Prof.SP2-Machine!

I am sure that SP2 is the problem because i have no problems on my non-SP2 Machines.

There is no further Information (so far i know) on the SP2-Readme and the Microsoft-Support Site.

How to use the StretchBlt to display bmp file as a size as I want?

hi,all
In my EVC4 project, I need to show a 800*600 bmp picture to a window which
size is 80*50,
I do it in the window's paint function:

Paint(CDC& dc)
{
CDC memDC;
memDC.CreateCompatibleDC(&dc);
HBITMAP oldBmp = (HBITMAP)::SelectObject(memDC.m_hDC, m_hBitmap);//m_hBitmap
is the my bmp picture's handle

StretchBlt(dc.m_hDC,0, 0, 80, 50 ,
memDC.m_hDC, 0, 0, 800 , 600, SRCCOPY);

memDC.SelectObject(oldBmp);

//Copy the content from Memory DC to current DC
dc.BitBlt(0, 0, 80 , 50, &m_MemDC, 0, 0, SRCCOPY);
//here, the picture was showed. But the size is not exactly as 80*50, it is
about 80*40
}

Does anyone happend it before?
And also, in msdn, in stretchBlt(), it says "The only raster operations
Windows CE supports in the dwRop parameter are SRCCOPY and SRCINVERT. Windows
CE does not support mirroring.

" What does mirroring means?

Thanks

Hi,

Just having a play around with the File control in eVB. Does anyone know how to use it to determine how many lines there are in a text file. I'm trying to send each line of a text file to a portable printer which I have working but need to know how to do the above.

Many thanks in advance.

hi!

i am writing a program that requires me to change the MAC address of my PDA
through a program. I have a C++ program to do just that - it changes the
value in the registry. To prevent a restart to allow the new MAC to take
effect, it uses functions in the Windows COM Interface that allow you
to change an adapter's MAC address without needing to restart. this needs
netcon.h which i cant find in the pocket pc SDK which leads me to velieve
that the functionality is not there for pocket pc.
so is there any other way to do this?

thanks

WinCE - display transparent bitmaps

JackSIL24-Sep-04 7:29

24-Sep-04 7:29

A question and some info...

Is it possible to write multiple bitmaps to a memDC and then 'copy' that memDC to a Device DC in order to avoid image 'flutter' or flicker?

Under Windows CE there is the ::TransparentImage function, for copying a memory DC to a Device DC with a transparent colour.

The function also accepts a bitmap handle in place of a memory DC: so there is no need to Select a bitmap into a memDC beforehand.

The following function demonstrates its use. In my project I make several calls to my function with diffent bitmap IDs to form a 'layered bitmap' image on the device DC (screen in my case).

void CWizzHMIDlg::DrawTransparentBitmapDirect( CDC *pDC, WORD BitmapID, POINT Posn, COLORREF TransparentColor)
// Copied specified bitmap, performs 'transparent copy' to specified DC - WITHOUT intermediate memory DC! WinCE only.
{
	CBitmap Bitmap;
	BITMAP BmpInfo;

	// Load the bitmap and gets its width & height
	Bitmap.LoadBitmap(BitmapID);
	Bitmap.GetBitmap(&BmpInfo);

	::TransparentImage(
			pDC->m_hDC,						  // Destination DC
			Posn.x, Posn.y,						// position of DC
			BmpInfo.bmWidth, BmpInfo.bmHeight,	 // size to copy from MemDC
			Bitmap.m_hObject,				 //  Handle of Bitmap (could be Source DC)
			0,0,								    // Position in source DC
			BmpInfo.bmWidth, BmpInfo.bmHeight,	// size is source DC
			TransparentColor);				 // Transparent color
}

I have tried various ways to copy several bitmaps on a memDC first, before copying to the device DC, but to no avail. Using a memDC parameter with TransparentImage does not appear to work more than once.

Connecting WinCE to MSDE and ADO.NET

Hi Is there any possibility to connect WinCE (Simpad) to regular MS SQL Server without SLQ Server CE and webservices?
My "mobile" devices are wall mount, so there's no need to local store data on them. I wanted to use regular SQL CLient as always do in windows forms but there is "PlatformNotSupportedException" thrown when playing with simulator - I've not tested it on physical device.
Any ideas?

Emulator Problem

Hello,

I developed a Web-Service which i want to consume from a Smart Device Application. I developed the Smart Device Application and create a Web Reference to the Web Service, but when i want to test the Smart Device Application in the Emulator the following error occurs:

A managed WebException occured at SoapHttpClientProtocol:doInvoke+0x23f

Unable to connect to the remote server

SoapHttpClientProtocol::doInvoke+0x23f
SoapHttpClientProtocol::Invoke+0x9
Service1::GetHypotenuse+0x17
Form1::ctor+0x3a
Form1::Main+0x5

Ok to terminate

Other Desktop WebClients which consumes WebServices on my Desktop works, and also a MobileWebApplication which consumes the same WEb-Service as the SmartDeviceApplication works, only when i want to test the Smart Device Application in the Emulator the error occurs. I think it may concerns the emulator because when i want to browse in the emulator in the pocket explorer to a site, it does not work. Cry | :((

Can anybody help me??

PocketPC Emulator, Problems with ActiveSync

I have a annoying problem with PocketPC emulator and ActiveSync.

Have followed http://blogs.msdn.com/exchange/archive/2004/02/23/78930.aspx and then installed Emuasconfig and Windows Mobile Powertoys as i have read in forums and on pages.

Did a search here and tried all kinds of things but keep getting an annoying error and can't use ActiveSync at all with the emulator!

The error message i am getting is

Error in starting ActiveSync Connection

I am out of ideas why it keeps giving me that.

If you use the Pocket PC 2003 emulator, you can use ActiveSync over ethernet. Read this article under the 'New Emulator' section:
