DLL built using EVC on a WM 5.0 device
Hi all,
I've a dll built with EVC++ 3.0 targetting a PocketPC 2002 device.
I want to use this on a WM 5.0 device.
Can I rebuild the same using EVC++ 4.0 with SP2/SP4and PocketPC2003 and use
the dll on a WM 5.0 device?
Any pointers are greatly appreciated.

CF 2.0 using interop with DCOM
I am trying to be able to create a DCOM interface and invoke a method within
Compact Framework 2.0. I am able to create the coclass. However, I keep
getting error 80004002 when I invoke any method or property on my DCOM
interface. I tried this with an inprocess COM interface and it works fine.
What am I missing. BTW, I am using standard OLE data types (BSTR's).

Wish List for Version 6 Compact Framework
I have written 2 applications using PDA phones for surveys. Would it be
possible to include voice recognition to the next software version. This
would mean surveyors could just dictate their results rather than fumble
with a fiddly stylus in cold weather.
Only a relatively limited range of words would need to be recognised

Setting DialogResult in OnClosing
In all the documentation on DialogResults it says that you can override the
DialogResult in the OnClosing event. I am working in VB and I just cannot do
this. I call ShowDialog with an OK in the top right. The form always returns
an OK whatever I do in the OnClose.
Is this an undocumented difference between CF and the desktop. Tag: Sound in VB.NET Tag: 62911
Problem using WM5 and ShGetSpecialFolderPath
Hi,
I'm using this function to find some folders.
It works fine with WM2003 and Pocket PC 2002.
With WM5 it throws a native exception most of the times.
The weird thing is that if I show a messagebox before calling the
ShGetSpecialFolderPath then it will work.
Does anyone know of a safe solution for using this function with WM5?

Opening forms in designer is slow with Visual Studio .NET 2005
I converted a VS .Net 2003 CF project to VS. Net 2005 keeping the target
version as CF1.0. After that when I tried to open any form in my project in

immediately. Also I noticed the forms that has lot of controls take long to
load. Can anybody tell me why this behavior is and any possible resolutions?

Error message - installing .NET CF 2.0 on device (CE .NET 4.20)
Greetings,
I am trying to deploy a VS 2005 Pocket PC app to the above mentioned
handheld (a PSC Falcon 5500). I dragged my CAB file over to the device, and
installed it, however the app will not run. I receive a brief hourglass,
then nothing happens.
I figured it might be that the device probably doesn't have the Compact
Framework 2.0 on it. I found the C:\Program Files\Microsoft Visual Studio
8\SDK\v2.0\CompactFramework\netcfsetupv2.msi file, ran it, went to Modify,
selected to install Deployment, and I get the following error:

Arrow Keys and Tabbing for WM5 using .NET CF 2.0
I am writing test applications with VS 2005 for the WM5 and have a questions
about the tabbing behavior related to the arrow keys.
When I have a MFC Smart Device application, using the arrow keys take the
focus to the
next control just as if a user tabbed.
(Note: I have the WM5 SDK Installed)
But when I have a .NET CF 2.0 application, the arrows keys don't take the
user to the next control. The controls have the Tab Stop and Tab Index
properties set properly. Is there something special needed to have the
arrow keys behave like the user is tabbing? Shouldn't this have been
automatic like the managed code's controls? Tag: Sound in VB.NET Tag: 62882

NumericUpdDown Overflow BUG!???!
I have a form with a NumericUpDown control, a ToolBar and an InputPanel.
The NumricUpDown is initialized as follows:
form.MinimizeBox = false;
nud.Minimum = 0;
nud.Maximum = 1000000;
When I call the form, it is constructed from an static method (singleton
form) and I call it as follows:
int i = 50000;
decimal d = Convert.ToDecimal(i);
nud.Value = d; // set NumericUpDown control value to 50000
form.ShowDialog(); // User can set the value to 50000 or some other number
int ii = Convert.ToInt32(nud.Value); // I get the wrong value --- negative
amount
MessageBox.Show(ii.ToString());
The problem is the value I get after the user has used the InputPanel to
changed the value, I get a negative amount, as if it were overflowing.
Could someonw help me confirm my bug, or am I seeing double!

Performance worrying problem - Bad architecture maybe
Hi guys,
I've got a very worrying problem in my CF 2.0 application. I don't know
the exact reason for so poor performance, sometimes combined with
"OutOfMemoryException" messages. Could be a bad architecture design
problem.
Ths is my actual scenario:
The application has got near 25 forms and I have one MasterForm from
which the rest of the forms inherit. This MasterForm contains basically
icons and some static variables I use for different purposes inside all
forms of my application.
I call the first form of my application "MainForm". Here we have three
very different choices (imagine three buttons).
When any button is clicked, I always open corresponding form with
ShowDialog() method. Each choice can simultaneously open 5/6 forms
maximum by using ShowDialog(). Therefore, I understand 5/6 forms are
opened in memory sametime. Correct me if I'm wrong please.
Imagine that I choose a button and navigate and navigate and.....I
finally have 5/6 forms opened with ShowDialog(). When I close the
actual modal form (fifth or sixth form), I use the simple this.Close()
and sometimes also return a DialogResult value. If the previous form
must perform an specific action, I use static variables of the previous
form, which I activate from the actual modal form.
In the previous form, I capture Activate event and do the correct
action if the corresponding static variable has been activated. An
example would be to save something and when returning to the previous
form, refreshing the screen with the newly saved data. This means a new
database access. This could be the main bottleneck of the application.
The operations are against SQL Mobile 2005 database. I always access
database to retrieve
latest data, don't use caching at all.
With this scenario, all I can tell you is that sometimes application
seems not to response, and ultimately, if you stress it hard,
"OutOfMemoryException" occurs and new data is not refreshed in the
screen. Suddenly data is "lost", and if you close the from and open it
again, data appears again......in one word: desperating!
I would like to hear any suggestion for a better performance please. It
really hurries me. My project is becoming more and more complex and I
think now, I've got the last chance to reorient or redesign its
architecture. 2006 could be too late.
Specially advices related to the way of opening/closing forms and
database accessing and caching.
Thanks very much. Regards. Tag: Sound in VB.NET Tag: 62815
Components on the PocketPC
Hello,
I'm starting to write for the Pocket PC. My first task is to translate
my current Windows components to Pocket components. Right on the
start, I can't reference a Windows component in my Pocket project, as
VS2005 is telling me.
My question: is it possible to have a common component project so that
I don't need two versions of the same code (one for the Windows, on for
the Pocket) ? For example, if I need to update the component, I don't
want to end up updating two times in two components that contains the
same code. I thought code re-use would be great since we're in .Net.
But it seems that the compact framework is not so close to the Windows
framework.
Thanks for the info,

HTTPS bug with web services in .NET CF v2.0?
Hello all,
I am writing a .NET Compact Framework v2.0 application which
communicates with a back-end system via a web service, using HTTPS for
transport. I am experiencing a problem where the first 256 characters
of the request are mysteriously cropped from the message before they
arrive at the server side. If I make the request over HTTP, it is
received correctly, so it only seems to be HTTPS which is causing the
problem. If I import the web reference into a desktop .NET Framework
application and call it from there over HTTPS it also works fine, I
have tried it using Apache Axis with Java as well which worked fine. As
such, the problem seems limited to the .NET Compact Framework. I am
about to try it with a v1.0 Compact Framework program to see whether
this is something that has been introduced since then.
Has anyone else come across a similar problem? Is it a known bug? If
so, are there any workarounds?

CF1.0 to CF2.0 problem after conversion
I am trying to convert an existing VS2003 .Net CF - C# app into VS2005 and
get the following error. I have verified that the file exists and is
referenced but I still get this error. I have a feeling this has to do with
the VS2005 beta2 screwing up my system (I'm now running the VS2005 release).
Any ideas would be greatly appreciated.
thanks.

Can't get rid of that task bar
Playing around with having a kiosk mode application on Pocket-PC, I always
end up with the task bar doesn't hide and is always on top.
I'm working with Visual Studio 8, C# and .NET 2.0. For testing I have a
Symbol PT-8800 and the emulated Pocket PC 2003.
First I've tried to maximize my form with code like this:
private void Form1_Load(object sender, System.EventArgs e)
{
// menu = null;
FormBorderStyle = FormBorderStyle.None;
WindowState = FormWindowState.Maximized;
}
Maximize does work, but the taskbar is not covered. It's hiding the top of
my form.
Next I've found that example code which is working with SHFullScreen().
Which hides the start icon with SHFS_HIDESTARTICON for some time, but
SHFS_HIDETASKBAR doesn't work. The input options menu on the right bottom
disappears too but only when SHFS_HIDETASKBAR is set, on the other hand
SHFS_HIDESIPBUTTON is ignored too. But anyway SHFullScreen is not the
solution I'm looking for, first it's not .NET (so far as I understand) and
second it will not work on CE Clients. Latter I cannot verify, 'cause "CE
4.2" will not work with .NET 2.0 and I don't have a "CE 5" emulation, but
that's another story.
So, how do I get a kiosk mode application in pure .NET and C#?

Problem with Databinding
Hi:
I have a winform with several tabs and controls in each one.
I build databinding:
Me.txtMarca.DataBindings.Add("Text", dtFhipec, "timbrado")
Me.oBMB = Me.BindingContext(dtFhipec)
dtFhipec is a Datatable, and oBMB is a property BindingManagerBase.
I delete last row, as following:
Me.oBMB.CancelCurrentEdit()
Me.oBMB.RemoveAt(Me.oBMB.Position)
Me.daFhipec.Update(Me.dsFhipec, "Fhipec")
Me.oBMB.EndCurrentEdit()
However, controls in form have sames values as before deleted row.

Any Windows CE devices that can replace PLCs?
Does anyone know if there are any companies producing stand-alone
Windows CE based "controllers" used for industrial applications? More
specifically, what I am looking for is a unit that contains the Windows
CE OS with possible support for CE .NET and the following:
* analog / digital inputs / outputs
* a display (at the minimum, a simple one line text display)
* a keybord input panel (not a computer keyboard)
* the ability to add expansion modules (more inputs/outputs and other
types of modules)
The unit must be rugged and designed for industrial purposes and should
be able to fit into some kind of rack or be designed to fit into a
panel cutout.. What I am looking for is something that could
potentially replace a PLC (programmable logic controller). Programming
in Visual Studio .NET in a language like C# or Visual Basic .NET is a
powerful solution that goes beyond typical ladder logic programming.
Any suggestions would be appreciated.
Thank you

Socket reuse problem
Argg.. another one of those CF vs normal framework things.
What I have is a program that creates a lot of socket connections over a
very short period of time (maybe a few hundread connections over a 2-3
minute period). What I am seeing is that it starts to slow way down in
terms of the Socket() constructor being called which I am thinking has to do
with the PDA running out of usable ports or something similar.
What I am using is BeginConnect() to establish my connection and if it takes
more then 1-2 seconds then I issue a Close() on the socket to abort it.
I have tried using multiple threads (one for each connection I will be
making) but I ended up running intoa OutOfMemory exception - even though I
tried calling the GC manually to free up old stuff.
Now what I have is just a single threaded class that has an ArrayList of
several classes that contain a Socket and other info in it. I use a timer
(100-1000ms interval) to loop through all the connections and check to see
if they are connected, timed out, etc. and then process the packets that are
recd. Right now I am only performing a connection attempt and then closing -
there is no send/recv implemented yet.
I hope this is enough of an overview to give you an idea of what I am doing.
I have tried using SetSocketOption() but it is hard to figure out what
is/not actually supported (aka actually works) in the CF. I have tried the
no linger option but it didnt help.
Any thoughts?
Anyone able to constantly open/close socket connections without any
probelms? I know on a PC I would expect to run out of ports (if they are
lingering around) after a few thousand but I am seeing problems on the PDA
after only a few hundread.
Thanks!

Textbox scrolling
VB 2005, .NET CF 2.0
Is it possible to append text to a multiline textbox without scrolling
vertically? If not, is it possible to get the vertical scrollbar's thumb
position and reset it after appending? I've tried using SendMessage with
EM_GETTHUMB but it always returns 0 and EM_LINESCROLL has no effect either.

How to create an event handler for a menu item?
I'm developing an app for a Pocket PC device.
I'm trying to create an event handler to a menu item as follows:
Dim mnuUndo As New MenuItem
mnuUndo.Text = "Undo"
mnu1.MenuItems.Add(mnuUndo, New EventHandler(AddressO
mnuUndo_Click))
but I receive this error:
Too many arguments to 'Public Function Add(mnue As
System.Windows.Forms.MenuItem) As Integer'.
How to accomplish that? And, by the way, I know .Shortcut is no
supported on CF, but is there a way to get around it?
Thank you for any help

Listview items on parent form listview does not display
I have an application that has a form with a listview.
It has a function that I call to start the unit to sync with different
providers depending on the platform they are syncing against. Each provider
is it's own class. One class syncs against our existing webservices, and
the other directly to a tcp object living on a legacy desktop application.
Since both of these provider classes needed a reference to the listview on
the form, they had private members where I would set the form on the class
property so the child classes could access the listview on the form.
I recently started a new application, and decided to try letting these
classes inherit from the form with the display / logging functions so they
could just call the base class functions to display status.
All of the syncing works fine, but when the child classes call the base
class functions to add items to the listview to display the status, none of
the items are visible.
The parent form is an abstract class which the "provider1" and "provider2"
classes inherit from.
Is there something I have to do special in this child/parent relationship to
make sure the items are visible? Tag: Sound in VB.NET Tag: 62766
The call to CabWiz.exe failed

I've tried changing dest and output lpaths but to no avail. When I look in
