I'm making some Animation project with Macromedia Flash 8, which uses ActionScript 2.0. I need some simple options like to save user to text file and read it. But, I couldn't find about writing to text file. Found some code that reads, but not writes.
Example of reading:
loadText = new LoadVars();
loadText.onData = function(raw) {
myField.text = raw;
}
loadText.load("user.txt");
Can someone help me, with examples of writing, parsing read data. Shortly, Working External data.
I appreciate any help that you can provide.

I need to develop a printer driver which can:-
Read the printed file (knowing the data inside the file)
Write extra information to the end of printed file. (eg. bar-code or QR code)
I plan to use V4 printer driver as template for me to start my development. I already tried to built this V4 printer driver in Visual Studio.
V4 printer driver solution explorer
Understanding the architecture of V4 printer driver may need lot of times. Besides that, I am still new in driver development, so it is hard for me to understand the document provided by Microsoft.
Can anyone suggest where should I start to code and recommend me any useful method/function or library. It will be useful if anyone can recommend some useful related reading material and what basic knowledge should I know.
See the Microsoft sample code here.
Create a "Render Filter" project (C++ project) in your "V4 Printer Driver" solution and add the sample code in "StartOperation_throws" method of newly created Render Filter.
Then use following sample code to add a custom content to your file:
XPS_COLOR testColor;
testColor.value.sRGB.alpha=0xFF;
testColor.value.sRGB.red=0xFF;
testColor.value.sRGB.green=0xFF;
testColor.value.sRGB.blue=0xFF;
testColor.colorType = XPS_COLOR_TYPE_SRGB;
FLOAT Font_Size = 14;
XPS_POINT OrgPoint = {123,123};
LPCWSTR TestStr = _T("Sample Text");
LPCWSTR Name_fnt = _T("SampleFontFile.TTF");
at the end, call "AddCustomTextToXpsDoc" using above parameters to add your text in
printable xps file.
So I've search everywhere. Xamarin Docs, goggle, here, W3.
All I need to do is store some small data in an XML file.
I created the XML, got the code lined up and when i go to build it.
IOS.....Can't find file.
I've googled the answer countless times, and they all say the same thing, Make sure it is set as Content or make sure it is "Embedded Resource" I've tried it both ways, It can't find the file to access it. Is IOS really that stupid? No issues in Android, took it 30 secs. Add it to the Assets and boom there it is.
But How to get IOS to Recognize xml file(find it)?
the code is this
XDocuent doc = new XDocument.Load("StoredLogs.xml") <that line is where it throws the error, through all the break points that it is.
After this it steps through a loop to bind the data in the xml to an object
Logs a.Id = x.Element("Id).Value......
a.name......... and so
All i want is basic offline storage.
iOS really that stupid?
Yes :P
When you add the XML file as an EmbeddedResource, you need to read it from the assembly instead of the path
For example:
var readme = typeof(NameSpace.App).GetTypeInfo().Assembly
.GetManifestResourceStrean("resourcename.xml");
using (var sr = new StreamReader(readme)) {
//Read the stream
}
I'm all new to Xamarin and I'm currently working on a sample or a "prove of concept" app using Xamarin.Forms.
I'm supposed to perform a print task from this app though I'm not at this point sure what to print yet (the screen, content of a label, a file etc.).
Either way, what is the easiest way to print from a Xamarin.Forms app?
(current target is primarily Android 4.4+).
I hope this isn't too complicated :)
EDIT:
Ok let me just update this post as the original text might be a bit ambitious/vague.
I have a Xamarin.Forms project (+ an Android part) and I have some HTML available in the XF part of the project that I need to get into a WebView and print it.
From what I understand, the thing with the WebView has to be done on the Android part of the project due to the fact that this is where the printing will be handled.
I was hoping this could be done from code since I don't really need to display the WebView, just print it's content.
The Android part of the project has only the MainActivity and no layouts or XAML files.
I don't know where to add the WebView or how to access it (other than DependecyService seems to be a buzz word here) so I'm kinda stuck here.
I'm thinking that this task should be rather trivial to someone with a little more Xamarin experience than me.
Every platform XF supports has it's own mechanism for printing. XF does not provide any abstractions for printing in a cross-platform manner. You will need to write printing logic for each layer and expose it to XF using DependencyService (or some other DI engine).
Here is a good example, of course, using dependency service:
https://codemilltech.com/xamarin-forms-e-z-print/
I so wanted to do this but it was too hard. Finally built it into Forms9Patch - a MIT licensed open source project.
Verifying that Printing is available
Before printing, you should verify that printing is available on your device. To do so, call:
if (Forms9Patch.PrintService.CanPrint)
{
// do the printing here
}
Print the contents of a Xamarin.Forms.WebView
using Forms9Patch;
...
var myWebView = new Xamarin.Forms.WebView
myWebView.Source = new HtmlWebViewSource
{
Html = "some HTML text here"
};
...
myWebView.Print("my_print_job_name");
Note that your WebView does not have to be attached to a Layout. This allows you to Print without having to display the WebView in your app’s UI.
Printing an HTML string
using Forms9Patch;
...
var myHtmlString = #"
<!DOCTYPE html>
<html>
<body>
<h1>Convert to PNG</h1>
<p>This html will be converted to a PNG, PDF, or print.</p>
</body>
</html>
";
...
myHtmlString.Print("my_print_job_name");
PLEASE NOTE: iOS sometimes places the page breaks in weird places. I have a StackOverflow Bounty on why this happens and how to fix it.
Using EmbeddedResource as a source for a Xamarin.Forms.WebView
This is sort of an experimental feature I’ve built that I’ve found it useful. As such the documentation is sparse. It allow you to put HTML content in a folder in your app’s EmbeddedResources folder and then use it as a source for a WebView. A much nicer solution than using platform specific approach provided by Xamarin. It also supports putting all of the HTML content into a zip file. Please take a look at the source code to see how it works.
You can handle the printing of lists/ invoices .. with the xfinium pdf component from xamarin componentstore. With that you create your _pdffile and then call the following method which starts the adobereader from where you can select a printer (in my case google cloudprint)
public void printPdfToCloud(string _pdffile)
{
try
{
var saveto = System.IO.Path.Combine(Android.OS.Environment.ExternalStorageDirectory.ToString(), "YourApp/"+_pdffile);
string file_path = saveto;
if (System.IO.File.Exists(file_path))
{
Android.Net.Uri pdfFile = Android.Net.Uri.FromFile(new Java.IO.File(file_path));
Intent pdfIntent = new Intent(Intent.ActionView);
pdfIntent.SetPackage("com.adobe.reader");
pdfIntent.SetDataAndType(pdfFile, "application/pdf");
pdfIntent.SetFlags(ActivityFlags.NoHistory);
StartActivity(pdfIntent);
}else
{
// give a note that the file does not exist
}
}
catch (Exception E)
{
// Do some Error dialog
}
}
I'm using Delphi 7 and I'd like to export the contents of a list from my program to OpenOffice Calc using automation, instead of using files.
The task is simple: create new document, iterate through rows/columns and change cell data.
I've found some code but it's not complete, and I was hoping someone has some example code ready to accomplish this very simple task. It could save me a few hours of trying.
Thanks in advance!
Edit: I'd like to automate OpenOffice Calc to achieve what I wrote above. Thanks!
The easiest solution is to write CSV file output, and open that in OpenOffice.
There are also libraries to write .XLS files which both OpenOffice Calc and Excel can read. CSV is so simple, I wonder that you need an example. Create a TStringList, and add strings to it, in comma separated format. Save to file.
The so called "programmatic" method involves OLE automation.
uses
OleAuto;
var
mgr,calc,sheets,sheet1,dt,args:Variant;
begin
args = VarArrayCreate(...);
mgr := CreateOleObject('com.sun.star.ServiceManager');
dt := mgr.createInstance('com.sun.star.frame.Desktop')
calc = dt.loadComponentFromURL('private:factory/scalc', '_blank', 0, args)
sheets = calc.getSheets()
sheet1 = sheets.getByIndex(0)
...
Open Office supports Automation

Good luck.
I don't really understand how Content importer/processor works in XNA.
I need to read a text file (Content/levels/level1.txt) of the form:
x x
x x
x x
where x's are just integers, into an int[,] array.
Any tips on writting a SIMPLE .txt importer??? By searching google/msdn I only found .x/.fbx file importer examples. And they seem too complicated.
Do you actually need to process the text file? If not, then you can probably skip most of the content pipeline.
Something like:
string filename = "Content/TextFiles/sometext.txt";
string path = Path.Combine(StorageContainer.TitleLocation, filename);
string lineOfText;
StreamReader sr = new StreamReader(path);
while ((lineOfText = sr.ReadLine()) != null)
{
// do something
}
Also, be sure to set the "Build Action" to "None" and the "Copy to Output Directory" to "Copy if newer" on the text files you've added. This tells the content pipeline not to compile the text file but rather copy it to the output directory for use as is.
I got this (more or less) from the RacingGame sample provided by Microsoft. It foregoes much of the content pipeline and simply loads and processes text files (XML) for much of its level data.
XNA 4.0 uses
System.IO.Stream stream = TitleContainer.OpenStream("tilename.txt");
See http://msdn.microsoft.com/en-us/library/bb199094.aspx and also http://blogs.msdn.com/b/shawnhar/archive/2010/12/09/reading-files-in-xna-game-studio-4-0.aspx
There doesn't seem to be a lot of info out there, but this blog post does indicate how you can load .txt files through code using XNA.
Hopefully this can help you get the file into memory, from there it should be straightforward to parse it in any way you like.
XNA 3.0 - Reading Text Files on the Xbox
http://www.ziggyware.com/readarticle.php?article_id=69 is probably a good place to start. It covers creating a basic content processor.
