Dpi-Aware experiments in V.S. 2005 Environment Hurricane300010-Jan-09 0:44 Hurricane3000 10-Jan-09 0:44  Hi all, I written the following code to make "DPI-Aware" the ImageSize property of an ImageList Control in my application (V.B. .Net C.F.2) in V.S. 2005 environment: Dim RK As Microsoft.Win32.RegistryKey = _ Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Drivers\Display\GPE") Dim LPX As String = CType(RK.GetValue("LogicalPixelsX"), String) Dim LPY As String = CType(RK.GetValue("LogicalPixelsY"), String) If LPX = 96 And LPY = 96 Then Me.ImageList1.ImageSize = New System.Drawing.Size(16, 16) Else Me.ImageList1.ImageSize = New System.Drawing.Size(32, 32) End If Well, I placed it in the Form1_Load event, and it works. But with doubt if that place was the "rigth place", I tryed to place it in the "Form1.Designer.vb" code (because I think it is the "more appropriate" place). I placed the first 3 line in the begin of code: <global.microsoft.visualbasic.compilerservices.designergenerated()> _ Partial Public Class Form1 Inherits System.Windows.Forms.Form Dim RK As Microsoft.Win32.RegistryKey = _ Microsoft.Win32.Registry.LocalMachine.OpenSubKey("Drivers\Display\GPE") Dim LPX As String = CType(RK.GetValue("LogicalPixelsX"), String) Dim LPY As String = CType(RK.GetValue("LogicalPixelsY"), String) 'Form overrides dispose to clean up the component list. <System.Diagnostics.DebuggerNonUserCode()> _ Protected Overrides Sub Dispose(ByVal disposing As Boolean) If disposing AndAlso components IsNot Nothing Then components.Dispose() End If MyBase.Dispose(disposing) and the "If-Else" conditions immediately above the ImageList.Add property code: If LPX = 96 And LPY = 96 Then Me.ImageList1.ImageSize = New System.Drawing.Size(16, 16) Else Me.ImageList1.ImageSize = New System.Drawing.Size(32, 32) End If Me.ImageList1.Images.Clear() Me.ImageList1.Images.Add(CType(resources.GetObject("resource"), System.Drawing.Image)) Me.ImageList1.Images.Add(CType(resources.GetObject("resource1"), System.Drawing.Image)) Me.ImageList1.Images.Add(CType(resources.GetObject("resource2"), System.Drawing.Image)) Also if it's recomanded to not write code-lines directly in .Designer.vb code, the code works correctly in both emulator and device, BUT sometime (I not understood why and in witch circumstances), only the If-Else conditions lines above are deleted and replaced with the single line: Me.ImageList1.ImageSize = New System.Drawing.Size(32, 32) And then I must replace it again, Of course, the problem is only in the debug phase, while after compilation there is no problem on device. I know that this is a "not easy" question but I hope that someone can help me to clear my ideas about where it's more appropriate to place above code. Thanks Re: Dpi-Aware experiments in V.S. 2005 Environment Joel Ivory Johnson10-Jan-09 2:42 Joel Ivory Johnson 10-Jan-09 2:42  You had it right the first time with placing the code in Form_Load. The designer section of the code is "owned" by Visual Studio and as you've seen VS does not gaurantee that changes you make to it will be preserved. If you plan to have others use and modify your code then the designer area isn't idea because no one else would know to look there for your code. Other than the Form_Load method the other place to consider would be in the constructor of the form right after the InitializeComponent method is called.

V.S. 2005 and Debug environment. Hurricane30009-Jan-09 8:44 Hurricane3000 9-Jan-09 8:44  Hi all. When I launch my application to be executed in PPC 2003 emulator, in the "Immediate Window" of V.S. 2005, appears 2 times the first error and 8 times the second error. A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll A first chance exception of type 'System.UnauthorizedAccessException' occurred in mscorlib.dll The "Error List" is empty (application doesn't contains errors and seems to works correctly). Application also seems to works correctly in real device. What can cause above errors, and how I can unnderstand witch piece of code lines that cause them? Thanks Re: V.S. 2005 and Debug environment. Joel Ivory Johnson9-Jan-09 17:41 Joel Ivory Johnson 9-Jan-09 17:41  It's from an exception being thrown and handled. It is safe to ignore. http://social.msdn.microsoft.com/forums/en-US/vssmartdevicesvbcs/thread/ac29e918-a966-44e8-910b-75c6cc12aabf/ Joel Ivory Johnson Meet my dev team: RDA Architecture Evangelist Team Blog My site: J2i.net Twitter: J2iNet Re: V.S. 2005 and Debug environment.

When you say "Logged out" do you mean you want the device to lock or you want your application to shut down?

Regards Re: Mobile number is displayed Lev Danielyan7-Jan-09 22:56 Lev Danielyan 7-Jan-09 22:56  I guess you are using Java and this is a Java security issue. AFAIK this is handled by the Java emulator/executing environment. Regards, Lev Re: Mobile number is displayed Chaser9210-Jan-09 1:03 Chaser92 10-Jan-09 1:03  Thank you very much, and possibly do you know how can I assign a managed stream to such handle that I obtain? Redirect another process' output to a stream Chaser927-Jan-09 8:39 Chaser92 7-Jan-09 8:39  Hello, my application needs to redirect a process' output to a stream, just like Win32's .NET did via StartInfo.RedirectOutputStream, but this function is missing in CF. Is there another way (maybe via P/Invoke?) Greetings Re: Redirect another process' output to a stream Randor 7-Jan-09 13:55 Randor 7-Jan-09 13:55  You seem to be searching for a managed method for accomplishing your goal. Unfortunately I don't know if there is other managed ways to redirect standard I/O. What I can tell you is that the unmanaged Win32 API that redirects standard devices is the SetStdHandle Function[^]. Good Luck, -David Delaune Re: Redirect another process' output to a stream Chaser9210-Jan-09 1:56 Chaser92 10-Jan-09 1:56  Which library contains the procedure in WinCE? this example seems to work only for Win32 Re: Redirect another process' output to a stream Randor 10-Jan-09 4:03 Randor 10-Jan-09 4:03  Chaser92 wrote: Which library contains the procedure in WinCE? You have my apologies. I did not realize that you were asking about an embedded environment. Perhaps you are looking for SetStdioPathW[^] and GetStdioPathW[^]? You can possibly use CreatePipe to create alternate input/output handles which are also opened from inside your application giving you complete input/output control. I think it could work like this: 1.) Call CreatePipe and save the handle to newhandle variable. 2.) Spawn a thread which reads the pipe handle. 3.) Call GetStdioPathW and save the handle to the a saved_output_handle variable. 4.) Call SetStdioPathW(1,newhandle). 5.) Call CreateProcess and your child process will inherit the parent i/o handles. 6.) Call SetStdioPathW(1,saved_output_handle) so you restore your own standard io handle. I hope I made sense... if not just ask.

Unmanaged code this would be the WriteFile Function[^]. Best Wishes, -David Delaune Re: Redirect another process' output to a stream thiagofiora16-Mar-09 2:49 thiagofiora 16-Mar-09 2:49  Hi Randor, I want to redirect the output of another process too, but in Windows Mobile. SetStdioPathW seems to work only in Windows CE. Do you know a function like SetStdioPathW that work at Windows Mobile? Thanks in advance.
