true. Microsoft acknowledges that there are scenarios (Especially business scenarios) that will not be possible for third party developers to implement on Windows Phone 7 with the access that they are giving us to the system today. But Miocrosoft has also repeatedly expressed that satisfying enterprise and business needs isn't first priority in the initial release of Windows Phone 7. ( see the Focus, Focus, Focus [^] blog post).

I thought that Ginny Caughey expressed the same concept so eloquently in the MSDN forums not long ago. In this post [^] she says "...for most folks, the measure of a phone isn't whether it has multitasking or a SQL database or removable storage, but how the thing works in their lives." The iPhone started to erode away at the Windows Mobile marketshare at release even without the ability to add applications. But it provided a great experience out of the box.

Needs for databases, network access, and other needs will be addressed later on. Right now Microsoft is concentrating on making a phone that provides a good user experience. For now note that Microsoft is still directing enterprises to Windows Mobile 6.5 for their mobile needs.

Developer training kits are now available for Windows phone 7 Series.

This training kit is geared for beginners who want to get started with developing applications for the latest Windows Phone operating system. Even if you don’t know Silverlight or XNA Framework, you’ll find this Training Kit useful. More seasoned Silverlight developers should also find this kit useful, as it explains some of the differences between Silverlight and Silverlight for the phone.

Get the course on Channel 9 at Windows Phone 7 Series Developer Training Kit[^].

Give us more details, it seems to be a problem with an external compilation and not a C# problem.

Hi
Is it possible to start an exe whenever the system reboots.

You can use the Windows\StartUp folder for this.
Put a shortcut/loader exe in here and it will automatically start them on boot.

Under WinCE if you put an EXE into an AutoRun folder then it will run at startup.

There is a folder named Start programs under windows directory. You should place the executable under it.

What a curious mind needs to discover knowledge is noting else than a pin-hole.

Hi I have an exe and I want to start it when the device reboots so I created a short cut of it in the StartUp folder with SHCreateShortCut API .... but when my device reboots the exe doen't start its gives a certification error dialog box stating that

"The file cannot be opened .Either it is not signed with a trusted certificate or one of the components cannot be found"

Actually I have an application and in the cab file of that application I have included that exe( in the Program Files folder) and i have tried to put that exe in teh wiindows startup.

Can anyone help me in t his regard as to how tackle this prob

I think I just answered your question in the MSDN forums. For others looking for the answer you need to change your device security settins so that it will run unsigned executables.

Connect your phone to your computer then in Visual Studio select Tools->Device Security Manager. From there you can change the device's security model to "Security Off"

You never allocate space for indexStore. If you know it'll always have 10 elements, declare it as

NSMutableArray *indexStore[10];

and

@property(nonatomic , retain) NSMutableArray *indexStore[10];

Fastest drawing with WinMo 6

Hi, i want to develop a small game for windows mobile with C#.
What is the fastest 2D drawing API? Im very used to XNA, so is there anything that I can use that's similar? I heard GDI is pretty slow.

Thanks

Strive to be humble enough to take advice, and confident enough to do something about it.

If you are drawing sprites then you should use DirectDraw. Unfortunatly DirectDraw isn't directly exposed to .Net developers. But there's another CodeProject article where some one declared all of the imports necessary to begin using DirectDraw from the .Net Compact Framework.

How can I use CeRunAppAtTime for a thread

Re: How can I use CeRunAppAtTime for a thread

8-Mar-10 0:03

Hi

I want a thread to start after 15/20 min For that can I use CeRunAppAtTime() .If yes can anyone provide me ways to do that.

Suppose this is my thread

void main()
{
..
..
g_handle= ::CreateThread( NULL, 0,MyThread, NULL, 0, 0);
....

}

Now I want This MyThread to start after 15/20 min can I do that

Thanks in advance

Joel Ivory Johnson10-Mar-10 7:35

10-Mar-10 7:35

Start your thread immediatly. When the thread starts have it to create an unnamed event. After creating the event the thread can call CeRunAppAtTime and pass the event handle. Then call the Wait function using the even't handle as athe parameter. The thread will be blocked from running until the event gets triggered.

For information on using CeRunAppAtTime with an event handle please see my comment at the bottom of This MSDN Documentation page[^]

I am using datagrid in my vb.net (pocket pc) application.

I am using the following code to set the tablestyle to the datagrid to adjust the column width

<pre>

Dim ts As DataGridTableStyle = New DataGridTableStyle

ts.MappingName = "Products"

Dim Product As DataGridTextBoxColumn = New DataGridTextBoxColumn
Product.MappingName = "Product"
Product.HeaderText = "Product"
Product.Width = 130
ts.GridColumnStyles.Add(Product)

Dim Qty As DataGridTextBoxColumn = New DataGridTextBoxColumn
Qty.MappingName = "Quantity"
Qty.HeaderText = "Quantity"

Qty.Width = 75
ts.GridColumnStyles.Add(Qty)

Me.DataGrid1.TableStyles.Add(ts)

Me.DataGrid1.TableStyles(0).GridColumnStyles(0).Width = 100

</pre>

After binding the datagrid I use this code to set the datagridtablestyle but it only show my one column me nothing even it does not return the values in the datagrid with original tablestyle. It show only row header in the grid but does not show the columns.

Any idea how I can solve this problem????

Thanks In advance
