Hi All  ,

Is there any class or library in .net is available.

Nope, there's no bluetooth interfaces in the .Net Framework or the .Net compact Framework. You might want to check out http://32feet.net

Hi everyone.
I just downloaded EC++ 4.0 and i have been trying hard to make it run on my Windows XP.
First of all it did not open because apparently "No standard SDK was found on the desktop....".
So i downloaded the Standard SDK 5.O and installed it on my pc.
This time Ec++ did open and i was able to open a project.
However when i tried compiling the program another error message was displyed...
" The application targeting a standard SDK for Windows CE.net and built for the SH4 CPU cannot be run on the Emulator device. Inorder to run this application on any CPU other than the Emulator you will have to install an SDK that is compatible with the standard SDK for Windows CE.net, the target a shadow platform pertaining to that SDK.
Please see EVC documentation for more details."
Can anyone please help me with this....
PS: The application i have been trying to compile is a remote control application written in Ec++ for a pocket PC running Windows CE 3.0.
Thanks in advance...

You may want to try using the IDE from ZHMICRO. It is based on C++, you dont need any SDK's, and the applications that you write can be run on other mobile OS's without changing any code.

Hi Deepali Khalkar,
Go to Active sync File Menu -> Connection Setting ... and Checked the "Allow connections to one of the following :" and select DMA and click on OK Button
then you got in your Project (IDE) Visual Studio select Tools - > Device Emulator Manager.. --> select your opened Emulator and right click on it and select cradle. now you are able to access internet.

Another way to enable internet connection:
* Open 'Emulator Properties' window using File->Configure menu.
* go to the network tab and check the 'Enable NE2000 PCMCI Network adaptor and bind to' chekcbox.
* select your machine's NIC card from the listbox.
* if you get a notification to setup proxy setting, choose anything and it should work.

I have tried with the following parameterised query for select statement and is working fine.
SqlCeConnection conn;
SqlCeCommand comm;
comm = new SqlCeCommand();
comm.Connection = conn;
comm.CommandText = "select * from signuptbl where username =@uname";
SqlCeParameter para = new SqlCeParameter();
para.ParameterName = "@uname";
para.Value = textBox1 .Text ;
comm.Parameters.Add(para);
Now i want to write an update query which takes multiple parameters. I have thought of the following code.
SqlCeConnection conn;
SqlCeCommand comm;
comm = new SqlCeCommand();
comm.Connection = conn;
comm.CommandText = "update signuptbl set firstname=@fname,lastname=@lname,,psw=@psw1 where username =@uname";
SqlCeParameter para = new SqlCeParameter();
para.ParameterName = "@uname";
para.Value = textBox1 .Text ;
comm.Parameters.Add(para);
para.ParameterName = "@psw";
para.Value = textBox2 .Text ;
comm.Parameters.Add(para);
para.ParameterName = "@fname";
para.Value = textBox3 .Text ;
comm.Parameters.Add(para);
para.ParameterName = "@lname";
para.Value = textBox3 .Text ;
comm.Parameters.Add(para);
I have tried this code but the row was not updated.
Is this a proper way? How to pass multiple parameters in a query? Can i get a sample code for the same.
Thanks in advance..

you declare single variable for parameter para and change the name and value multiple time. Instead of this, use multiple variable for parameter. use following code
<br />
SqlCeParameter para1 = new SqlCeParameter();<br />
para1.ParameterName = "@uname";<br />
para1.Value = textBox1 .Text ;<br />
comm.Parameters.Add(para1);<br />
<br />
SqlCeParameter para2 = new SqlCeParameter();<br />
para2.ParameterName = "@psw";<br />
para2.Value = textBox2 .Text ;<br />
comm.Parameters.Add(para2);<br />
<br />
SqlCeParameter para3 = new SqlCeParameter();<br />
para3.ParameterName = "@fname";<br />
para3.Value = textBox3 .Text ;<br />
comm.Parameters.Add(para3);<br />
<br />
SqlCeParameter para4 = new SqlCeParameter();<br />
para4.ParameterName = "@lname";<br />
para4.Value = textBox3 .Text ;<br />
comm.Parameters.Add(para4);
also specify the type of parameter
hope this helps

I am developing an application on Win mobile 5.0 emulator in C# using Visual studio 2008.
Can anyone let me know how to write an SQL statement in C# which returns the row count?
Is the parameter required to store the count value?
I will be greatefull if someone helps with the code snippet for the same.
I have tried the following code for the select statement(the select stmt does not return the row count value) and is working fine.
String uname_in='abc';
SqlCeConnection conn;
SqlCeCommand comm;
SqlCeDataAdapter adap = new SqlCeDataAdapter();
String connstring = @"Data Source=Program Files\signup\signupdb.sdf";
conn = new SqlCeConnection(connstring);
conn.Open();
comm = new SqlCeCommand();
comm.Connection = conn;
comm.CommandText = "select * from signuptbl where username =@uname";
SqlCeParameter para = new SqlCeParameter();
para.ParameterName = "@uname";
para.Value = uname_in;
comm.Parameters.Add(para);
adap.SelectCommand = comm;
System.Data.DataTable dt = new DataTable();
ap.Fill(dt);
psw1 = dt.Rows[0][1].ToString();
What changes should be done in the above code for writing a select stmt the return the number of rows selected?
Thanks in advance.

Hi Deepali Khalkar,
In SQL Query you can use count() mehtod for getting selected rows count.
see the below example.
private int GetRowCount()
{
int intCount = 0;
SqlCeConnection objCon = new SqlCeConnection("ConnectionString");
objCon.Open();
SqlCeCommand objCmd = new SqlCeCommand("SELECT COUNT(*) AS UserCount FROM Users", objCon);
intCount = System.Convert.ToInt32( objCmd.ExecuteScalar().ToString());
objCon.Close();
objCmd.Dispose();
return intCount;
}
hope this may be help...

FYI "SELECT ROWS" should be faster that "Select Count(*)"

Hi,
I am using CF3.5 on Windows CE5.0 and when I try to create a bitmap using:
Bitmp bmp = new Bitmap(filepath)
I get the exception error below. I also tried loading file into MemoryStreamm and then tried creating bitmap by passing a memory stream with all bytes corresponding to image but I get same error.
I tried loading bmp, jpg, png images but none work. The device I am using is an iPAQ310. Is it possible that it's missing some kind of codec or some driver that compact framework assumes it to be there? If so, what is it missing?
Thanks in advance for any help you can provide.
System.Exception was unhandled
Message="Exception"

You may want to install onto your device the resource DLL that contains the detailed error messages.
What is the resolution of the image?

Hi Joel, I already tried embedding a simple bmp 5x5 pixels into my exe and still got same problem. I have been digging into it and the problem seems to be that the device I am programming into (HP iPAQ 310) does not have the necessary dll's required by framework. The framework uses gdiplus.dll. Then I believe gdiplus.dll uses gdi32.dll and this dll itself uses coredll.dll.
The only one available in this device is coredll.dll and since it's in ROM, I am not able to even place another dll in the windows location. I would have to contact HP to have them provide me a new ROM version that contains this functionality.
However, this device has some neat 3D games so the alternative would be to figure out what library those games use. Problem is that I will have to go back to C++ for that.

please,
Can any one give me the code in VB .Net to create today item in pocket pc

The Today items are implemented in COM and the .Net CF doesn't lend itself well to implementing such components. see this[^] for more details.

Hi,
When i am trying to set PreferredConnections using DMProcessConfigXML API for a GPRS connection. It returns the standard error code E_INVALIDARG.Can any one tell me why this is happenning? and what does it mean?.
WAP provisioning xml i passed into DMProcessConfigXML function is
<wap-provisioningdoc><characteristic type="CM_Planner">
<characteristic type="PreferredConnections">
<parm name="{8928DE37-C914-4db4-90E9-C5213E475A77}" value="MyGPRS"/>
</characteristic>
<parm name="FailoverPrompt" value="1"/>
<parm name="FailoverDefault" value="1"/>

Thankful to you any kind of help.

Hello Shakir,
Your input string does not seem to be erroneous but there may be few reasons for this error.
1. The hosting server becomes inactive for any reason.
2. Failover has an internal timeout so even after making the connection successfully it may give this error if one of the resources within the connection group fails.
3. It is strictly OEM dependent and service provider dependent so please cross check with a different PDA and different service provider.
