Hi
I am making a simple smart device project in C# where I have a login screen and I want to store the data using SQL Server CE. I have followed this link to connect my smart device project with the database, but I am finding problem

http://www.codeproject.com/KB/mobile/loginsmartdevicedatabase.aspx

In this link in the last section it says that after we build our project we will be able to see the data table adapter frame in the toolbox which we can drag into the project and can work but after building the project I am not able to see that frame anywhere in the tollbox. Can anyone help me as to why this is happening

Thanks in advance!!!!

Hi

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.

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

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

I think you can use SetTimer() with a timer proc. http://msdn.microsoft.com/en-us/library/ms644906(VS.85).aspx[^]

SetTimer requires a message pump but my dll doesnt have any. So i cant use it. I need an alternative of Sleep() so that i can use it
