i want to print out of my c# application on my hendheld , but i cant find the Printdocument object. After a bit of searching i find out that the printdfocument doesnt exist in the compact framework. But is there another my to print with my WLan PCL5 printer?
All these third party lib like PrintCe are very expensive and i think i dont really need them because, i want to use the PCL5 Interface of my printer. I cant imagine that the only way to print something in compact framework should be third party softwráre, which is ten years old and very expensive. I mean printing is a very common thread.
Can anybody me out?
thanks!
The Compact Framework has no printing capabilities. You can roll your own - I did this way back in the CF 1.0 days, creating a 1bpp image, drawing everything to it, then shipping that to the printer, but it was a lot of work (some of it can be found here) and really it only supported the specific report I was making for the specific Zebra printer I was targeting.
Becasue of the complexity involved, just about everyone that I have ever known to do printing in the CF has used PrinterCE or PrintBoy.

Does anyone know of any good free libraries providing Windows Forms controls for displaying schedules/timetables in .NET? I'm really looking for something similar to what the guy who asked this question was seeking, with a couple of differences:
I don't need any help organizing the underlying data or generating the schedule (that's all set) -- I just want a clean way of displaying it.
I'm actually looking for a custom control in Windows Forms, not an ASP.NET control.
One thing I've considered doing is just using a TableLayoutPanel control, but ideally I'm looking for something that will be more straightforward code-wise (as in, something actually designed for displaying a timetable) and sharper-looking visually.
How about this control? It is very similar to the calendar in Outlook. It does come with source code, so if it's not quite what you need you could maybe use this as a base for your own implementation.

He built a control (CalWidget) that you can easily recompile in your own project that's pretty nice. I recompiled it in .net 4.0 with little problems.
I am creating a program for mac that needs to generate reports and be able to print them as PDF files. I would rather find an already created library for this rather than hard-coding everything, but I can't find anything yet. Do you recommend any report generation libraries that can be used in Objective-C?
Thanks for your help!
Haven't looked at it in a pretty long time, but you might want to check out ReportMill. It goes way back to the NeXTSTEP days.
If you are online and can call a web service, then you can get Docmosis to produce a PDF report and deliver it wherever. I've seen this done in objectve-c from an iPad.
I know this will be a difficult question, so I am not necessarily looking for a direct answer but maybe a tutorial or a point in the right direction.
What I am doing is programing a robot that will be controlled by a remote operator. We have a 3D rendering of the robot in SolidWorks. What I am looking to do is get the 3D file into VB (probably using DX9) and be able to manipulate it using code so that the remote operator will have a better idea of what the robot is doing. The operator will also have live video to look at, but that doesn't really matter for this question.
Any help would be greatly appreciated. Thanks!
Sounds like a tough idea to implement. Well, for VB you are stuck with MDX 1.1(Comes with DirectX SDK) or SlimDX (or other 3rd party Managed DirectX wrapper). The latest XNA (replacement for MDX 1.1/2.0b) is only available for C# coder. You can try some workaround but it's not recommended and you won't get much community support. These are the least you need to get your VB to display some 3d stuffs.
If you want to save some trouble, you could use ready made game engine to simplified you job. Try Ogre, and it's managed wrapper MOgre. It was one of the candidate for my project. But I ended up with SlimDX due to Ogre not supporting video very well. But since video is not your requirement, you can really consider it. Most sample would be in C# also, so you need to convert to VB.Net to use. It won't be hard.
Here comes the harder part, you need to export your model exported from SolidWorks to DirectX Format (*.x). I did a quick search in google and only found a few paid tools to do that. You might need to spend a bit on that or spend more time looking for free converter tools.
That's about it. If you have more question, post again. Good Luck
I'm not sure what the real question is but what I suspect that you are trying to do is to be able to manipulate a SW model of a robot with some sort of a manual input. Assuming that this is the correct question, there are two aspects that need to be dwelt with:
1) The Solidworks module: Once the model of the robot is working properly in SW, a program can be written in VB.Net that can manipulate the positional mates for each of the joints. Also using VB, a window can be programmed with slide bars etc. that will allow the operator to be able to "remotely" control the robot. Once this is done, there is a great opportunity to setup a table that could store the sequencial steps. When completed, the VB program could be further developed to allow the robot to "cycle" through a sequence of moves. If any obstacles are also added to the model, this would be a great tool for collission detection and training off line.
2) If the question also includes the incorporation of a physical operator pendent there are a number of potential solutions for this. It would be hoped that the robot software would provide a VB library for communicating and commanding the Robot programatically. If this is the case, then the VB code could then be developed with a "run" mode where the SW robot is controlled by the operator pendent, instead of the controls in the VB window, (as mentioned above). This would then allow the opertor to work "offline" with a virtual robot.
Hope this helps.
I have the following requirements:
I need a api that works on CE (x86) + .NET Compact Framework to play videos (Similar to CorePlayer API... Just free)?
Is their anything else available or must I use CorePlayer?
You could use the MediaPlayer with COM interop. Have a look at this and this.
Also, Media Player may not be installed in your device.
You need to use DShow and have the codecs for whatever media you intend to play in the image. COM interop for WMP 9.0 (which is what ships up through at least CE 5.0, maybe also in 6.0) is a non-starter for managed code.
If you don't know DShow, it's a fair amount of work - even in native code - as DShow is not a fun or friendly API set.
The plus side is that you don't need WMP at all in the image, so you can typically use a Core CE license (Pro is required to use WMP). I know of a commercial DShow control, but you said you're looking for a free solution and I'm not aware of anything other than rolling your own. Depending on your level of familiarity with COM interop (which you'll need for the DShow stuff) and the use of DShow and filtergraphs, I'd allocate at least a week or two to getting this working.
One added note - the complexity also changes depending on how you want the video displayed. If it's just full-screen then it's a bit less work than getting it inside a Window within your app. Not a lot less, but at least a little.
DirectShow?
Check out this page for a starting point.
Provided that DirectShow is present on your CE, which I don't know...
EDIT: Since you can use DirectShow, I'd like to add a bit.
As ctacke notes, it can be a lot of work if you do everything manually, but it's pretty straightforward if you can use IGraphBuilder (see the sample I linked above).
I don't know much about DirectShow versions, but the one included with Windows Mobile 6.0 lacks a splitter for MPEG audio. It means, e.g., that out of the box it won't play .mp3 files unless you wrap them in RIFF headers.
I bet you can convert some of DirectShow.Net to run on CE if you are looking for a C# solution.
I'm looking at rewriting an eMbedded Visual Basic app I wrote years ago. I'm unsatisified with it because of various problems clients keep having with it now and then over the years, mostly along the lines of the app not loading anymore because a required dll/activex control has gone missing! This is so frustrating and naturally difficult to debug when a client is using it far away. In alot of cases reinstalling the app doesn't fix the problem.
My preference would be to rewrite it in C# since I'm comfortable with C# and DotNet, but I'm also open to other platforms like blackberry or iTouch/iPhone so long as the platform can support maps and GPS. I'd start rewriting it in C# now but I can't be sure that I won't have the same problems in .net.
Has anyone else had similar problems with eVB apps which have gone away/persisted when moving to CF DotNet? Or would you suggest a different platform again?
Edit: Note that I wish to move away from eVB anyway, but if I move to CF DotNet I want to make sure I won't have the same missing dll/control problems.
I recommend .NET CF strongly, especially if you already know C# and .NET. Mono has been ported to the iPhone, so it is possible to write apps that will run on Windows Mobile and the iPhone. No Mono for Blackberry (yet, if ever), so that's a definite limitation. I personally can't stand Blackberries (I have both a Blackberry and a WM smartphone and the Blackberry makes me want to hang myself), but they do have a huge user base.
You should have migrated away from eVB years ago, but that's water under the bridge. If you want to continue targeting Windows CE/ Windows Mobile I'd recommend going to the CF - language is irrelevant, use what you're comfortable with.
There's no way to guarantee that whatever your "missing DLL" problem is won't happen again, since we have no idea what DLL went missing. If it was a 3rd party control, then you're at the mercy of the market. If the provider survives, it's likely their control will.
If you want to target iPhone/Blackberry then Java is more likely to be your language of choice - the tools I'm not as familiar with. Eclipse for Blackberry - iPhone may have their own tool.
As for Silverlight, you might look at it, but so far it's just way too slow to be a viable platform, at least on any WinMo device I've ever seen. We've delevered many, many CF apps for all sorts of verticals and have never had any usability problems (though we've been doing it a long time and know every limitation and what we should and should not be trying).
I suggest you take it one step further and look at Silverlight. One of the premises is that it's a more long-term-stable, portable, lightweight download and install, and it hasn't gotten krufty yet.
I think it has the potential to be the next VB for embedded. One of the difficulties with CF is that I've found it to be an insufficient subset of the real thing.
Another option is NS Basic/CE. It's highly compatible with eVB, so you will be able to keep most if not all of your code. The product has been continually updated so it runs on current devices.
The installer that NS Basic/CE creates includes all the dll files your program requires, so they will be included on installation.
