dotnet compact framework : newbie question - how to enumerate font
I'm using CF 1.0 and VB.net 2003. I wish to enumerate all the character fonts available into the system, and the proper size of each one. The idea is to achieve something like this (pseudo-code): Dim avilableFonts As Fonts Dim arraySizesOfThisFont() As Integer For index=1 to avilableFonts.Count fontName = avilableFonts(index).name arrayOfSizesOfThisFont = avilableFonts(index).sizes.toArray() MyComboBoxFontList.add(fontName) MyComboBoxCurrentFontSize = arrayOfSizesOfThisFont Next and, after selecting a font into first "MyComboBoxFontList", the second "MyComboBoxCurrentFontSize" fills up with the character sizes of the selected font. There's a way to do this? Thanks in advance Francesco
I've found this example... it could be usefull for me if it will run.
But an error occurs: MissingMethodException at FontList_Create() Please help me!! ' YaoDurant.Drawing.FontCollection.vb - Font enumeration ' wrapper class for FONTLIST.DLL.

A search of this newsgroup for "enumerate" and "font" turns up several relevant discussions, including one I posted back in March ( http://groups.google.com/group/microsoft.public.dotnet.framework.compactframework/browse_thread/thread/b8415fcc040204f8/a767eab055c88691 ). As it happens, I'm familiar with the book the sample code came from. Several of their managed demo projects make use of native C++ helper DLLs. This one is looking for a file called "fontlist.dll". If you don't have that DLL included in your project, then there's no method to be found. I've got one piece of bad news and two pieces of good news for you. The bad news is that the sample code download page on their website is no longer working properly, so you can't get fontlist.dll from there. The good news is that I happen to have both the C# and VB sample archives stored away, and I've mirrored them on my website at http://www.isquaredsoftware.com/code.php . The even better news is that since this question has come up a few times, and I haven't yet seen a definitive answer, I took some of my free time today and put together a sample that shows how to do this using 100% managed code. Note that this _does_ require CF 2.0. I've uploaded the sample ZIP as EnumFontFamiliesDemo.zip, also available from http://www.isquaredsoftware.com/code.php . For future reference, and for the benefit of the search engines, I've put the code for Form1 at the bottom. All necessary structures have been declared in another file, based on the definitions in MSDN. Hope this helps!

Don't worry about your English. I've been teaching English outside the US for the last couple years, and trust me - you're doing just fine :) As for this project - first off, I suggest you learn about about something called "P/Invoke". That 's the system that .NET uses to communicate with "unmanaged" (C / C++ / etc) code, especially DLLs. Basically, you tell .NET the name and information of the DLL function you're interested in, and then you can use it from C# or VB.NET. Here's a couple of useful pages explaining it in more detail: http://msdn2.microsoft.com/en-us/library/aa288468.aspx http://www.beansoftware.com/NET-Tutorials/Unmanaged-Code-PInvoke.aspx Second, there are a couple utilities out there which will convert VS2005 projects backwards into VS2003 projects: http://www.codeproject.com/KB/cs/WhidbeyProjectConverter.aspx http://www.csksoft.net/blog/post/UnPrjConvertor.html (note: appears to be written in Chinese, and may only work for C++ projects) Anyway, in order to list fonts, we really need to use that EnumFontFamilies function. The problem is that EnumFontFamilies requires that you give it a "callback" function. Every time EnumFontFamilies finds something interesting (like the name of a font), it passes that to your callback. It's relatively easy to create a callback in C++, but harder in .NET. More importantly, CF 2.0 has the ability to make one, but CF 1.0 doesn't. Because of this, the only way to do this from CF 1.0 is to create a DLL of your own that creates a callback, calls EnumFontFamilies, and then passes that information back up to your .NET program. Happily, the authors of "Programming the .NET Compact Framework in C#/VB.Net" already did this for us - the "fontlist.dll" that your sample is looking for, which is included in the sample code for their book. Go to http://www.isquaredsoftware.com/code.php and download the link marked "VB.NET sample code", down at the bottom. That links to a file named YaoDurantCFSource1.0-VB.zip, which is the sample source from their book. If you extract that somewhere, there's two things inside that are useful here. First, look for YaoDurant\CPP\Ch16_TextAndFonts\FontList \FontList.cpp. That's the C++ source code for fontlist.dll. Second, look in YaoDurant\VB\Ch16_TextAndFonts\FontPicker. They've got a VB sample project that not only demonstrates how to use fontlist.dll, but also actually does much of what you're asking. If you look in YaoDurant.Drawing.FontCollection.vb, you'll see how they use the DLL and its functions from VB.NET. Also, the project files should be compatible with VS 2003. Finally, do you know what kind of processor your navigation system is using? If it's ARM, then you can use the fontlist.dll that's included in the project. If it's something else, you may need to recompile the DLL yourself so that it can run on your system. Let me know how things go from there. Mark Erikson
Thanks Mark,
Thank you very much for spending your time for us!!! Google has given to me several responses to my question but, the "must", always was "CF2.0", as also your requirement! As further trouble, I've started programming vb.net for 1 month.... I'm the really newbie. I've to tell you however, no response I've found is very satisfying as your and no-one has taken the trouble to do a useful sample. I'm programming my Navigation System... not a PocketPC... so, I can't update CF 1.0 to v. 2.0. I can't even update operative system... both are into Flash memory and I wouldn't touch ti for keeping product warranty... All I can do is... programming reasonably [VB.net 2003]+[CF1.0]+[WinCE5.0]. What I need is something would run with first version of CF. I've downloaded your project: my .net 2003 says "project created with newer version of Visual Studio". Ok... I've opened each file instead the project... code is C#... I haven't found VB code. I've searched for vb code... no source found!!! But I'm afraid that, even though I succeed to "understand" your C# code and manage it into mine, I will be not able to install it into my navigation system cause CF incompatibily. I've searching for fontlist.dll... as you foreseen, it is available no more! Looking at Fonts Functions into MSDN (http://msdn2.microsoft.com/en-us/library/ms901099.aspx), I'm not be able to find the way to use Windows CE native functions... as I've said before... I'm not skilled about this argument. Any idea to "outflanking" CF2.0? Thanks again!!! P.S.: I hope my bad english has made myself clear!!!

Thanks again Mark
A good dictionary can deceive an US teacher?!! :) Excuse me... I've become blind: the link you have mentioned last post was manifest but I've fixed my glassy stare on "EnumFontFamilies" and I've not seen the rest of the text!! I think next Christmas will be spent on studying P/Invoke and Chinese!! ;) Processor has ARM-architecture (ARM926T-AT4X0A)! The simpliest operation I've made is generating FontPicker (compatible with VS2003) and installing it to device. Executing the exe, as if by magic it appeared before me: the solution!!! Next step is to implement the solution in my application... I think this will not so hard. Thanks Mark... you have saved my head!!
