sounds like a very sensible work around, otherwise you would have to find the function that posts WM_KEY msgs rewrite it, tie ur on keyhandler when ur app starts then tie the normal handler when ur app exits.... messy and would prob interrupt other functionality with the device =(

Hello,

I was wondering if anyone knows an alternative to receive sms to a personal computer other than through a GSM Modem. I really find this method quite slow than using kannel project.

Any reply would be greatly appreciated. Thanks in advance Big Grin | :-D

could look for a WCDMA cell network but i doubt u will be able to tell the difference.

SQLCE Connection Problems

Hello!
I am facing some problems on the development of my mobile simlpe application connecting to an SQLCE database.
After searching a bunch of sites, tutorials and Q&A's my code seems to be correct and I can't figure out what's going wrong.

This is my code:

SqlCeConnection conn = new SqlCeConnection("Data Source=ChokweDB.sdf");
SqlCeCommand insertForm1 = new SqlCeCommand("INSERT INTO Form1Table (p1,p2,p3,p4,entrevistador,data) values ('" + p1.Text + "','" + p2.Text + "','" + p3Value + "','" + p4Value + "','" + txtEntrevistador.Text + "','" + txtData.Text + "')", conn);
conn.Open();
insertForm1.ExecuteNonQuery();
conn.Close();

My database is placed in the home directory of the application (filename ChokweDB.sdf). When I run the code, MVS2008 will simply not find the database:

The database file cannot be found. Check the path to the database. [ Data Source = ChokweDB.sdf ]

Why oh why? What am I missing?

Hi Vafo,

in your code you have to specify exact database path.

<br />
string DBPath = @"Program Files\ChokweDB.sdf";<br />
SqlCeConnection conn = new SqlCeConnection("Data Source=" + DBPath );

hope this will help you...

Can't build, unrecogized escape sequence error after each dash...seen this before..

string dbconn = "@C:\Documents and Settings\Vasco\Ambiente de trabalho\Serviços de Informática\ChokweMobile\ChokweDB.sdf";
SqlCeConnection conn = new SqlCeConnection("Data Source=" + dbconn);

And after some correcting...

<pre> string dbconn = @"C:\Documents and Settings\Vasco\Ambiente de trabalho\Serviços de Informática\ChokweMobile\ChokweDB.sdf";
SqlCeConnection conn = new SqlCeConnection("Data Source=" + dbconn);

Returns Path not valid.

And...

string dbconn = @".\ChokweDB.sdf";

The database file cannot be found. Check the path to the database. [ Data Source = .\ChokweDB.sdf ]

The database IS o the same folder as the application - and it really IS there and the name is spelled correctly..

Try this

string path = "Data Source =";
path += System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);

path += "\\Database.sdf";

then

myConnection = new SqlCeConnection(@path);

Radio Buttons Styling (Windows Mobile 6)

I have a very basic question but have lost some time wondering and digging the webs for an answer already - should be extra easy to answer tho:

I am developing a windows form for Windows Mobile 6 in C#, using Visual Studio 2008. I have two sets of radiobuttons in a form, and I want to separate them. I have learned I should use the WS_GROUP option, but the dumb question is...
"Where/how do I set this WS_GROUP option?"
Appreciate some reply - thank you for your attention

Can you confirm the development language that you are using? WS_GROUP is a windows style constant that is used in programs written in C/C++. For C# you would accomplish grouping radio buttons by either placing them in the same container (groupbox or panel).

You might want to check out the XmlTextReader class or the ReadXml method of the DataSet object (Depending on what you are doing).

Why not just make your own transformation matrix class?

Also check SourceForge which i also think has some code to cover this (svg for cf).
Good luck Smile | :)

Hi everyone!

I have had so much help from this wonderfull site! Its time to give something back Smile | :)

I have made a really nice RAD framework for making finger-friendly apps for WM. Its called GSlide and is a teeny-tiny-bit revolutionary in its architecture i must say. Most importantly really easy to work with!

Check it out and please give me feedback!

Hi, thanks for your question Smile | :)

GSlide operates slightly different than other frameworks since it uses more of a new component architecture with exe files responding to outside procedure-calls.
The nice thing about this is that prototyping can be VERY rapid, even be accomplished on your actual device.
GSlide is in other words not "installed" or used as a GUI component in the normal VS manner.
Think of GSlide developing more like client/server, or browser/server, developing.
Play around with the script-files on your device, or in the desktop emulator to get started. There are also examples in the menu on the site.

Im working on fun tutorials!

Why I couldn't get WM_KEYDOWN when left&right softkey is pressed ?

Guo_yt16-Apr-09 17:51

16-Apr-09 17:51

I use VS2005 create a smart device project, select WM5-PPC SDK and application type = windows application.
In "WndProc", I print every message with the flowing code,

if(message != WM_TIMER)
{
TCHAR str[256] = {0};
_stprintf(str,_T("message = %d \r\n"),message);
OutputDebugString(str);
}

But when I press the left softkey or the right, I didn't receive a WM_KEYDOWN message,
Does anybody knows something about this or any solution?

Thanks in advance.

Hook keys, top most and notification

[germany]merlot15-Apr-09 2:52

Hello.

For my current Windows Mobile application I need to hook all hardware keys like the Green button (answer call) or the Red button (end call). How can I do this preventing the user to skip my app.

Another problem I have is to keep my app always on top. I'm using the P/Invokes:

ShowWindow(this.Handle, SetWindowState.SW_SHOW);
SetForegroundWindow(this.Handle);
SetActiveWindow(this.Handle);

but without a real success.

The third thing is how can I suppress the incomning call notification on a windows mobile phone? Or better how can I suppress/disable all popup notifications like "Cannot connect"-bubble, "Low battery" warning or incoming call notification?

I hope someone can give me an answer to this questions. Thanks in advance.

Best regards, merlot
