I found an example that I'm trying to use for a reference, but it is doing stuff with pictures, and I just want to display text.
It is using the following functions:
BeginPaint()
LoadString()
SHLoadImageResource()
CreateFontIndirect()
GetClientRect()
DrawText()
GetClientRect()
DrawText()
EndPaint()
There is a little more, but I think this is the gist of writing to the screen.
In tinkering with this example, I keep breaking it trying to figure out which parts are the parts that write just the text; while not displaying the image.
The code I'm using (I can't remember where I found it, it might have been here, but I can't find it again) displays a picture with a text caption under it.
I'm trying to see how the text part works byt removing the image part, so it just displays the caption.
When I do it, I get the caption with the first picture, but not the second picture. The screen is just blank.

FYI:
OK, I got through this, and I am drawing rectangles and filling with text
fbrush = CreateSolidBrush(bcol);
FillRect(ps.hdc, &rect, fbrush);
wsprintf(szLabel, TEXT("Remove"));
rect.top += 2;
rect.left += 2;
DrawText(ps.hdc, szLabel, -1, &rect, DT_LEFT | DT_NOPREFIX | DT_SINGLELINE);
This is creating a rectangle on the screen, filling it with a specified color, and writing the text "Remove" in the rectangle.
The problem I was having was the code I was refering to had an image that it was displaying with text under it. I had problems figuring out what was the image part and what was the text part. I basically just looked at the functions, and read about them at MSDN, and created what I have above.
The one thing I can't figure out is the background color for the text.
The rectangles I'm using are filled with a background color, but the text background fills with white.
I have not been able to find where to change that, there does not seem to be an option for DrawText.
Anyone know?

OK, a little more searching and I found this:
SetBkMode(ps.hdc, TRANSPARENT);
to make the text background transparent.
I thought it would be part of the Font or DrawText.

Please help.
I read this message

//playsound(@s[1],0, SND_FILENAME);<br />
playsound('tst1.wav',0, SND_FILENAME);<br />
writeln(f,'played');<br />
close(f);<br />
end.
and compiled with ppcrossarm (FreePascal).
As a result I got "hello.exe is not a valid PocketPC application", BUT
this is not compiler error. If comment the execution of playsound() all works fine. So, Coredll.DLL don't contains PlaySound function.
If packed by UPX just halts without any message.
Where I can find good description of all functions of dll's of WM5?
Or if exists an opensource program for windows Mobile 5.0 that plays wma or mp3 and controls the "speed dial" button... Google found nothing.
Thanks.
Sorry for my bad English.

Dear Code Project,
i am currently developing a Management system for a university which can be used on mobile. Currently the company already have a Management system but it is desktop based. I am just putting few and important modules to be access via mobile.
It will be more likely a website which they can access through mobile. they will be able to take a picture and send it to database, able to view reports and perform certain tasks.
i am planning to use ASP.net Mobile for this.
Would like to hear your suggestion and feedbacks or any recommendations you have.
I really need certain technical information. Its for my final year project
Thanks.
Note: Admin, please do not hesitate to move this thread to another forum if suitable.

It sounds like you already know the direction in which you should go. But for the most part it sounds like you are describing a typical smart client that would have online and offline functionality. You may want to check out the Windows Mobile Line of Business Accelerator[^] as it will contain a lot of solutions for issues you may encounter.

Basically it will be more like a webpage which can be accessed through mobile device. I am planning to make it through ASP.NET with Access database. user can point the location through their browser and then they'll be able to perform certain task. Like generate reports, marketing statistics, upload picture.
Do you know any other mobile based management system which i can refer as my literature review.
Thanks.

Hi,
Our company has decided to use SQL Server compact Database for our mobile application. We want to use LINQ to SQL, but SSCE does not support dbml designer. Is it possible to SQLMetalBuilder tool to generate dbml code for SSCE? If it is possible, how to use the tool?
Also can sqlMetal.exe be used with SSCE to generate dbml code?
Thanks in advance,
Veena

hi.
i want to launch multiple instances of my .NET CF 3.5 application on a pocket pc. there were a solution for .NET CF 1.0 here[^], but it's not suitable for .NET CF 3.5 because now there is a window with class name #NETCF_AGL_PARK_<path-to-application>, and changing window text doesn't help...
do anyone know any other solutions of this problem?
De profundis clamat...

Would you mind describing why you need multiple instances of your program? There may be other work-arounds that will work for you but before we know if they are appropriate for consideration we would need to know what you are trying to do.

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

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.

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

It's from an exception being thrown and handled. It is safe to ignore.

Hi guys
Just heard that the Nokia Developer Conference in Bangalore got postponed.
Mighty happy to hear that as I could not register myself earlier. It was supposed to take place on December 10, 2008 now because of terrible Mumbai terror attacks it got postponed to January 20, 2009.
Venue remains the same - Trinity, Taj Residency, Bangalore, India
Just thought there are people like me out there who too missed out earlier. To register and know other details visit www.Nokiadevcon.in
