Yes, you can install Compact Framework 1.0 and 2.0 side-by-side. Microsoft claim, however, that if CF 2.0 is installed, CF 1.0 is not necessary. See for example here[^]. Note that both Windows Mobile 2003 SE and Windows Mobile 5.0 have .NET CF 1.0 in ROM, but these might not be the latest versions.
We recently discovered that a Windows Mobile 5.0 Pocket PC Phone Edition device we're using suffers from 'DLL crunch'. This is where a process allocates enough memory for data that there is not enough space left to load any more DLLs. For more information on this issue see Windows CE .NET Advanced Memory Management[^] in MSDN Library. In our case it was actually device.exe, the process that hosts drivers, that was failing, and this caused all sorts of odd problems.
One of the issues here was that we were loading .NET Compact Framework 2.0 SP1 and SQL Server 2005 Mobile Edition (SQL Server CE) from persistent storage rather than the ROM version, which is CF 1.0. CF 2.0 SP1 and SQLCE come to about 3MB of DLLs all by themselves, which is enough to move from the out-of-box configuration on this device to the DLL Crunch state. Part of the problem is that Windows Mobile 5.0 Pocket PC Phone Edition now has so many, large, execute-in-place (XIP) DLLs that they've overflowed the 32MB area added in Windows CE 4.0 (discussed in the linked article) and started consuming a large part of your process address space again, leaving only around 18MB free for the application.
For this reason it might be sensible to stick with CF 1.0, but note that CF 1.0 is seriously cut-down compared to the desktop. CF 2.0 is a bit better in this regard.

Hi,
I have an ASUS P535 and I have a problem with GPS. If I use TomTom Navigator, I don't have any problem, but if I use the gps sample from Microft I have the next problem:
- Sample project: Microsoft.WindowsMobile.Sample.Location (ProgramFiles\Windows CE Tools\wce500\Windows Mobile 5.0 Pocket PC SDK\Samples\Cs\Gps)
- Error: In the function WaitForGpsEvents the code stop indefinitily WaitForMultipleObjects
- The Microsoft sample, haven't any problem in HTC P3300
- The code and error:
private void WaitForGpsEvents()
{
lock (this)
{
bool listening = true;
IntPtr handles = Utils.LocalAlloc(12);
Marshal.WriteInt32(handles, 0, stopHandle.ToInt32());
Marshal.WriteInt32(handles, 4, deviceStateChangedHandle.ToInt32());
Marshal.WriteInt32(handles, 8, newLocationHandle.ToInt32());
while (listening)
{
int obj = WaitForMultipleObjects(3, handles, 0, -1); (!!!!!ERROR STOP HERE indefinitely!!!!!!!!!!!!!!!!!!!).
if (obj != waitFailed)
{
switch (obj)
...
{
case 0:
// we've been signalled to stop
listening = false;
break;
case 1:
// device state has changed
if (deviceStateChanged != null)
{
deviceStateChanged(this, new DeviceStateChangedEventArgs(GetDeviceState()));
}
break;
case 2:
// location has changed
if (locationChanged != null)
{
locationChanged(this, new LocationChangedEventArgs(GetPosition()));
}
break;
}
}
}
// free the memory we allocated for the native handles
Utils.LocalFree(handles);
// clear our gpsEventThread so that we can recreate this thread again
// if the events are hooked up again.
gpsEventThread = null;
}
}
Some idea or solution?
Thank you

Does the Asus provide gps sharing through a virtual port scheme. If so this may be your problem. The workaround would be to implement your own polling and NMEA sentence data parsing routine.
I experienced a problem on an HP Travel Companion with the serial port data received events when the virtual port feature was being used. The virtual port feature is intended for sharing of the gps port by multiple applications.
When I disabled the feature and accessed the port directly the data received event was fired. If I enabled the feature I had to use a polling routine to get the serial port data.
I do not think that this is a bug. I am not sure how I would implement a data received event for multiple listeners when using virtual ports.

Hello,
I am trying to implement a feature on the PDA Application (Windows CE/ C#). There is a button and a label. While this button is pressed and remains pressed, keep changing/incrementing the content of the label.
This seems to fit a mouse down/up event very well, but unfortunately there is no mouse down/up for the button on .NET compact Framework 2.0.
Thanks for helping,
|
|
|
|
|
The only way that I know to do this is to make your own button class derived from control. Then you can use the mouse events from the control class.

Since my question in the C# forum did not get the right results (or with other words: None *G*), I better ask herein.
All I need is simply a hit-test on a polygon, means to detect of a point is laying within my polygon.
There is no polygon class in .NET CF 2.0 (requires common .NET 3.0), and there is no support for GraphicsPath to build a region other than circles, rects, etc...
Is there any Polygon class out there for me that would support a hit-test? Just giving it the 2-dimensional points which create the polygon, and checking if another point is in it.
Thanks in advance
|
|

|

Since there was no ready-to-use class and I was not about to write an own polygon class that can handle complex forms and calculates for intersection or point in polygon, I made an quick hack. :-p
I simply use a temporary white bitmap in the memory, I make DrawPolygon into with red, and then check for the pixel where the point to check is.
I know, dirty hack, but it works under .NET CF where I have no GraphicsPath etc.

Hi,
I would like to change the font and size of text in static text...
I have been able to change color. here are the command lines I use to do that.
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0, 0, 255));//blue
But have not found a say to set the font or font size. Is it possible to set the font size and color for a static text control in MS CE C++ (v4.0)? If it is can anyone give me a hint of how to do this?
Thanks

Create a CFont object and use SelectObject to select it into the DC. Save the return value. Once you've finished with your font, use SelectObject again to select the previous font back into the DC (this is important to ensure that your font object is disposed of properly).
This is assuming you're drawing your text with DrawText or TextOut or similar. If you want to affect the font of a static control, create a CFont object that has a lifetime at least as long as the control (for example, make it a member of the dialog class) and call SetFont on the control.
For more, read "Programming Windows, Fifth Edition" by Charles Petzold (dates from 1998, but still completely as relevant as ever) or "Programming Windows with MFC, Second Edition" by Jeff Prosise (equally old, equally still relevant).

Hi all.
I have developed a mobile web page in ASP.NET and it runs fine when running it on its own in VS.NET. I need to run it from a mobile device emulator to see how it looks,etc. I have tried this in the browser of the emulator :"http://localhost:2175/DemoGhostDigest/MobileArticle.aspx" but it says I am not connected.

Am I missing something? Please assist.
