  ![alt text][1] [1]: http://s48.radikal.ru/i120/1005/ff/6e439e04bbc8.jpg hi what i'm trying to achieve is #1 but what i get is #2 it seems linear layout stacks with height of it's first element and shrinks second's element height to that. the xml for those is the following: <?xml version="1.0" encoding="utf-8"?> android:layout_weight="5" / android:text="Aaa aaaaa aaa aaaaa, aaaaaaa aaa aaa a, aaa aa aaaaaaa aaa aa.

• Flex URLRequest Timeout

  - by MooCow

  I have a Flex program that gets a JSON array from a PHP script. The PHP script doesn't contain just a simple JSON array but it grabs data from Activecollab and do some work on the data before encoding the data. The first test involve a small JSON array that took a short time to encode by PHP. However, when I try to scale up the test, the Flash movie will crash trying to load the JSON data from PHP. There's no code difference between the tests, just the amount of data and amount of time it takes PHP to encode. Am I looking at a memory problem or a time out problem? PS: When I call the PHP script in Firefox, it doesn't time out and still return a JSON array. It just took awhile to return the array.

• Upload file via HTTP from VBA (WinHTTP)

  - by chiccodoro

  Hi all, I'm trying to HTTP upload a binary file programmatically from within VBA. I intend to put an ASPX page on the server. I know there are lots of nice ways to do that (e.g. use web service instead of aspx), but my constraint is that it must run in VBA (in an excel file), and that I cannot install any additional components on the client. So I guess I'll use WinHTTP, and I've found several examples to post form data, but not to post a binary file. I probably need to base64 the file contents? If so, please let me know. If I can make WinHTTP do file encoding for me, please let me know. If there is a much better way to reach my goal (Upload file from within VBA, server needn't necessarily be ASPX, could be a ASP.NET-Web service as well), please let me know... Thx, chiccodoro

• C# Stream Reader adding \n to XML

  - by Terry

  I use the StreamReader class to obtain XML for my GeoCoding process from Google. StreamReader srGeoCode = new StreamReader(WebRequest.Create(Url).GetResponse().GetResponseStream()); String GeoCodeXml = srGeoCode.ReadToEnd(); XmlDocument XmlDoc = new XmlDocument(); GeoCode oGeoCode = new GeoCode(); XmlDoc.Load(GeoCodeXml); I get XML back but it adds \n and other extras to the XML <?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<kml xmlns=\"http://earth.google.com/kml/2.0\"><Response>\n <name> I have the same code in VB and it does not do this. I can successfully GeoCode my information using the VB version of this console app. Is there a reason the C# version adds this extra data to the XML that I retrieve back? I am trying my best to convert everything over to C#. I enjoy coding in it over VB.

• Issue parsing RSS xml

  - by cw

  Hello, I'm having an issue using Linq to XML parsing the following XML. What I am doing is getting the element checking if it's what I want, then moving to the next. I am pretty sure it has to do with the xmlns, but I need this code to work with both this style and normal style RSS feeds (no xmlns). Any ideas? <?xml version="1.0" encoding="UTF-8"?> <rdf:RDF xmlns:rdf="http://someurl" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"> <channel rdf:about="http://someurl"> XElement currentLocation = startElementParameter; foreach (string x in ("channel\\Title").Split('\\')) { if (condition1 == false) { continue; } else if (condition2 == false) { break; } else { // This is returning null. currentLocation = currentLocation.Element(x); } } Thanks!

But when I'm using XslCompiledTransform etc.. output starts from <html xmlns="http://www.w3.org/1999/xhtml">. So, Doctype is missed. Why? Right properties of XslCompiledTransform initialized just like I set in . How can I get DOCTYPE from XslCompiledTransform?

• how can I translate a NSString to NSData? And the data has the same content as the string

  - by someonemaybe

  NSString * theString=@"e88d"; NSData * data; // something I should implement NSLog(@"%@", theString); NSLog(@"%@",[data description]); I want the results of the two printings are the same. AES encryption and decryption: (1).The server: if the plaintext is :@"abcd"; the AES encrypted data(NSData data type) is :"d882830c dc892036 4345839f 13c7516a"; (2).in my local app, my code is : NSData*data=[NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://..."]]; NSString * mystring= [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; However, to decrypt data successfully, I must got a data(NSData date type) which equals to "d882830c dc892036 4345839f 13c7516a".But it is the mystring (NSString data type) not the data(NSData data type) that equals to the right value. the encryption and decryption function both need a data(NSData data type) as input datas. (NSData*)AES128EncryptWithKey:(NSString*)key; (NSData*)AES128DecryptWithKey:(NSString*)key;

• Exceptions using CruiseControl.NET

  - by Andy

  I recently updated to CC.NET 1.5 and I'm now getting some strange exceptions. On one project I get: - ThoughtWorks.CruiseControl.Core.CruiseControlException: Source control operation failed: svn: Can't create a character converter from native encoding to 'UTF-8' This happens when CC is checking a subversion repository for any mods. If I run the actual command line CC says is failing it works and returns an empty XML (there are no mods). Some other projects also fail to check mods with another "Source control operation failed" exception but no further info. Again the command is an "svn log" which when run from command line works ok. I'm using subversion 1.4.5 client side and my source repository exists on a separate box than my build server. Anyone got any ideas?

• Parsing XML using xml.etree.cElementTree

  - by Andre

  I have the following XML in a string named 'xml': <?xml version="1.0" encoding="ISO-8859-1"?> <Book> <Page> <Text>Blah</Text> </Page> </Book> I'm trying to get the value Blah out of it but I'm having trouble with xml.etree.cElementTree. I've tried the find() and findtext() methods but nothing. Eventually I did this: import xml.etree.cElementTree as ET ... root = ET.fromstring(xml) element = root.getchildren()[0].getchildren()[0] Element now equals the element, which is what I want (for this solution anyway), but how do I get the inner text from it? element.text does not work. Any ideas? PS: I am using Python 2.5 atm. As an extra question: what is a better way to parse xml strings in python?

• How to remove accent characters from an InputStream

  - by Samuh

  I am trying to parse a Rss2.0 feed on Android using a Pull parser. XmlPullParser parser = Xml.newPullParser(); parser.setInput(url.open(), null); The prolog of the feed XML says the encoding is "utf-8". When I open the remote stream and pass this to my Pull Parser, I get invalid token, document not well formed exceptions. When I save the XML file and open it in the browser(FireFox) the browser reports presence of Unicode 0x12 character(grave accent?) in the file and fails to render the XML. What is the best way to handle such cases assuming that I do not have any control over the XML being returned? Thanks.

  I'm new to objective-c and Im trying to write a little sample app that gets some XML from a remote server and outputs it to the console, but when I do it I get a EXC_BAD_ACCESS which I dont understand: NSString *FeedURL = @"MYURLGOESHERE"; NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:FeedURL]]; NSURLResponse *resp = nil; NSError *err = nil; NSData *response = [NSURLConnection sendSynchronousRequest: theRequest returningResponse: &resp error: &err]; NSString *theString = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; NSLog(@"Response: %@", theString);]; [resp release]; [err release]; When I comment out the [resp release] line I dont get it anymore, can someone please explain this to me :) Thanks

• Using python to play two sine tones at once

  - by Alex

  I'm using python to play a sine tone. The tone is based off the computer's internal time in minutes, but I'd like to simultaneously play one based off the second for a harmonized or dualing sound. This is what I have so far; can someone point me in the right direction? from struct import pack from math import sin, pi import time def au_file(name, freq, dur, vol): fout = open(name, 'wb') # header needs size, encoding=2, sampling_rate=8000, channel=1 fout.write('.snd' + pack('>5L', 24, 8*dur, 2, 8000, 1)) factor = 2 * pi * freq/8000 # write data for seg in range(8 * dur): # sine wave calculations sin_seg = sin(seg * factor) fout.write(pack('b', vol * 127 * sin_seg)) fout.close() t = time.strftime("%S", time.localtime()) ti = time.strftime("%M", time.localtime()) tis = float(t) tis = tis * 100 tim = float(ti) tim = tim * 100 if __name__ == '__main__': au_file(name='timeSound1.au', freq = tim, dur=1000, vol=1.0) import os os.startfile('timeSound1.au')
