• How do I launch a WPF app from command.com. I'm getting a FontCache error.

  - by jttraino

  I know this is not ideal, but my constraint is that I have a legacy application written in Clipper. I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using: SwpRunCmd("C:\MyApp\MyBat.bat",0) The batch file contains something like this command: C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application" It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application. Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is: The type initializer for 'System.Windows.FrameworkElement' threw an exception. at System.Windows.FrameworkElement..ctor() at System.Windows.Controls.Panel..ctor() at System.Windows.Controls.DockPanel..ctor() at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl) at System.Windows.Forms.Integration.ElementHost..ctor() at MyCompany.MyApp.AppWin.Main.InitializeComponent() at MyCompany.MyApp.AppWin.Main..ctor(String[] args) at MyCompany.MyApp.AppWin.Program.Main(String[] args) The type initializer for 'System.Windows.Documents.TextElement' threw an exception. at System.Windows.FrameworkElement..cctor() The type initializer for 'System.Windows.Media.FontFamily' threw an exception. at System.Windows.Media.FontFamily..ctor(String familyName) at System.Windows.SystemFonts.get_MessageFontFamily() at System.Windows.Documents.TextElement..cctor() The type initializer for 'MS.Internal.FontCache.Util' threw an exception. at MS.Internal.FontCache.Util.get_WindowsFontsUriObject() at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection() at System.Windows.Media.FontFamily..cctor() Invalid URI: The format of the URI could not be determined. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString, UriKind uriKind) at MS.Internal.FontCache.Util..cctor() If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected. The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon. If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in). One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior. We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work. We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations. To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference). Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them. Thanks!

• Ubuntu 12.04 LDAP SSL self-signed cert not accepted

  - by MaddHacker

  I'm working with Ubuntu 12.04, using OpenLDAP server. I've followed the instructions on the Ubuntu help pages and can happily connect without security. To test my connection, I'm using ldapsearch the command looks like: ldapsearch -xv -H ldap://ldap.[my host].local -b dc=[my domain],dc=local -d8 -ZZ I've also used: ldapsearch -xv -H ldaps://ldap.[my host].local -b dc=[my domain],dc=local -d8 As far as I can tell, I've setup my certificate correctly, but no matter why I try, I can't seem to get ldapsearch to accept my self-signed certificate. So far, I've tried: Updating my /etc/ldap/ldap.conf file to look like: BASE dc=[my domain],dc=local URI ldaps://ldap.[my host].local TLS_CACERT /etc/ssl/certs/cacert.crt TLS_REQCERT allow Updating my /etc/ldap.conf file to look like: base dc=[my domain],dc=local uri ldapi:///ldap.[my host].local uri ldaps:///ldap.[my host].local ldap_version 3 ssl start_tls ssl on tls_checkpeer no TLS_REQCERT allow Updating my /etc/default/slapd to include: SLAPD_SERVICES="ldap:/// ldapi:/// ldaps:///" Several hours of Googling, most of which resulted in adding the TLS_REQCERT allow The exact error I'm seeing is: ldap_initialize( ldap://ldap.[my host].local ) request done: ld 0x20038710 msgid 1 TLS certificate verification: Error, self signed certificate in certificate chain TLS: can't connect. ldap_start_tls: Connect error (-11) additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed After several hours of this, I was hoping someone else has seen this issue, and/or knows how to fix it. Please do let me know if I should add more information, or if you need further data.

• Gitlab and Nginx not loading gitlab

  - by paperids

  I have just installed gitlab and nginx on Ubuntu LTS 12.04 using this guide: http://blog.compunet.co.za/gitlab-installation-on-ubuntu-server-12-04/ I installed this on another server last night and had absolutely no problems with it (sort of a test run to see how long it would take to get going). I am not getting any errors when restarting gitlab or nginx with /etc/init.d and my error logs are empty. The only thing I know of to go on is the vhost config: upstream gitlab { server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.sock$ } server { listen localhost:80; server_name gitlab.bluringdev.com; root /home/gitlab/gitlab/public; # individual nginx logs for this gitlab vhost access_log /var/log/nginx/gitlab_access.log; error_log /var/log/nginx/gitlab_error.log; location / { # serve static files from defined root folder;. # @gitlab is a named location for the upstream fallback$ try_files $uri $uri/index.html $uri.html @gitlab; } # if a file, which is not found in the root folder is r$ # then the proxy pass the request to the upsteam (gitla$ location @gitlab { proxy_redirect off; # you need to change this to "https", if you set "ssl" $ proxy_set_header X-FORWARDED_PROTO http; proxy_set_header Host gitlab.bluringdev.com:80; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://gitlab; } } If there's any other information that would be helpful, just let me know and I'll get it up asap.

• Nginx all subdomain points to one subdomain (gitlab) rule

  - by Alkimake

  I have installed gitlab on my server and use nginx as http server... I simply used recipe for gitlab on nginx # GITLAB # Maintainer: @randx # App Version: 3.0 upstream gitlab { server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.socket; } server { listen 192.168.250.81:80; # e.g., listen 192.168.1.1:80; server_name gitlab.xxx.com; # e.g., server_name source.example.com; root /home/gitlab/gitlab/public; # individual nginx logs for this gitlab vhost access_log /var/log/nginx/gitlab_access.log; error_log /var/log/nginx/gitlab_error.log; location / { # serve static files from defined root folder;. # @gitlab is a named location for the upstream fallback, see below try_files $uri $uri/index.html $uri.html @gitlab; } # if a file, which is not found in the root folder is requested, # then the proxy pass the request to the upsteam (gitlab unicorn) location @gitlab { proxy_read_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694 proxy_connect_timeout 300; # https://github.com/gitlabhq/gitlabhq/issues/694 proxy_redirect off; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://gitlab; } } gitlab.xxx.com works fine and i get gitlab web documents. But if i want another subdomain i use for Jira (jira.xxx.com) on port 80 (i setup jira on 8080 port normally) gets gitlab web site also. How can i restrict this rule only serving for gitlab, or may be i can redirect jira.xxx.com to jira.xxx.com:8080

• Nginx ignores HTTP Authentication for WordPress login directory

  - by MrNerdy

  I am running WordPress in a subfolder of my domain for testing and development purposes on a VPS LEMP-stack. In order to password-protect the wp-login.php with an etxra layer, I used HTTP authentication for the wp-admin folder. The problem is that the http authentication is ignored. When the wp-login.php or wp-admin-folder is called, it goes directly to the normal WordPress-login. I installed everything from the command line in the following way: sudo apt-get install apache2-utils sudo htpasswd -c /var/www/bitmall/wp-admin/.htpasswd exampleuser New password: Re-type new password: Adding password for user exampleuser My Nginx configuration file looks like this: server { listen 80; root /var/www; index index.php index.html index.htm; server_name example.com; location / { try_files $uri $uri/ /index.html; } location /bitmall/wp-admin/ { auth_basic "Restricted Section"; auth_basic_user_file /var/www/bitmall/wp-admin/.htpasswd; } location ~ /\.ht { deny all; } error_page 404 /404.html; error_page 500 502 503 504 /50x.html; location = /50x.html { root /var/www; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 location ~ \.php$ { try_files $uri =404; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } I would appreciate your advive on this.

• Dynamic nginx domain root path based on hostname?

  - by Xeoncross

  I am trying to setup my development nginx/PHP server with a basic master/catch-all vhost config so that I can created unlimited ___.framework.loc domains as needed. server { listen 80; index index.html index.htm index.php; # Test 1 server_name ~^(.+)\.frameworks\.loc$; set $file_path $1; root /var/www/frameworks/$file_path/public; include /etc/nginx/php.conf; } However, nginx responds with a 404 error for this setup. I know nginx and PHP are working and have permission because the localhost config I'm using works fine. server { listen 80 default; server_name localhost; root /var/www/localhost; index index.html index.htm index.php; include /etc/nginx/php.conf; } What should I be checking to find the problem?

• nginx rewrite or internal redirection cycle

  - by gyre

  Im banging my head against a table trying to figure out what is causing redirection cycle in my nginx configuration when trying to access URL which does not exist Configuration goes as follows: server { listen 127.0.0.1:8080; server_name .somedomain.com; root /var/www/somedomain.com; access_log /var/log/nginx/somedomain.com-access.nginx.log; error_log /var/log/nginx/somedomain.com-error.nginx.log debug; location ~* \.php.$ { # Proxy all requests with an URI ending with .php* # (includes PHP, PHP3, PHP4, PHP5...) include /etc/nginx/fastcgi.conf; } # all other files location / { root /var/www/somedomain.com; try_files $uri $uri/ ; } error_page 404 /errors/404.html; location /errors/ { alias /var/www/errors/; } #this loads custom logging configuration which disables favicon error logging include /etc/nginx/drop.conf; } this domain is a simple STATIC HTML site just for some testing purposes. I'd expect that the error_page directive would kick in in response to PHP-FPM not being able to find given files as I have fastcgi_intercept_errors on; in http block and nave error_page set up, but I'm guessing the request fails even before that somewhere on internal redirects. Any help would be much appreciated.

• nginx- Rewrite URL with Trailing Slash

  - by Bryan

  I have a specialized set of rewrite rules to accommodate a mutli site cms setup. I am trying to have nginx force a trailing slash on the request URL. I would like it to redirect requests for domain.com/some-random-article to domain.com/some-random-article/ I know there are semantic considerations with this, but I would like to do it for SEO purposes. Here is my current server config. server { listen 80; server_name domain.com mirror.domain.com; root /rails_apps/master/public; passenger_enabled on; # Redirect from www to non-www if ($host = 'domain.com' ) { rewrite ^/(.*)$ http://www.domain.com/$1 permanent; } location /assets/ { expires 1y; rewrite ^/assets/(.*)$ /assets/$http_host/$1 break; } # / -> index.html if (-f $document_root/cache/$host$uri/index.html) { rewrite (.*) /cache/$host$1/index.html break; } # /about -> /about.html if (-f $document_root/cache/$host$uri.html) { rewrite (.*) /cache/$host$1.html break; } # other files if (-f $document_root/cache/$host$uri) { rewrite (.*) /cache/$host$1 break; } } How would I modify this to add the trailing slash? I would assume there has to be a check for the slash so that you don't end up with domain.com/some-random-article//

• Nginx map module 301 redirecting

  I've rebuild my website in Ruby on Rails and now I want to 301 redirect a lot of old urls using Nginx's http://wiki.nginx.org/HttpMapModule For some reason I can't get it to work.

• Nginx deny doesn't work for folder files

  I'm trying to restrict access to my site to allow only specific IPs and I've got the following problem: when I access www.example.com deny works perfectly, but when I try to access www.example.com/index.php it returns "Access denied" page AND php file is downloaded directly in browser without processing.

• Configuring nginx to check for hard files in only a few directories,

  - by Evan Carroll

  For a node.js project I'm doing, I have a tree like this. +-- public ¦   +-- components ¦   +-- css ¦   +-- img +-- routes +-- views Essentially, I have the root to be set to public. I want all requests destined to /components/ /css/ /img/ To check to see if their appropriate destinations exist on disk. However, I don't want requests to other directories to even run an IO operation, /foo/asdf /bar /baz/index.html None of those should result in the disk being touched. I have a stansa that does the proxy to node.js, location @proxy { internal; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-NginX-Proxy true; proxy_pass http://localhost:3030; proxy_redirect off; } I just would like to know how to arrange this. My problem would be easily solved if try_files took a single argument, but it always wants a file first. location /components/ { try_files $uri, @proxy } location /css/ { try_files $uri, @proxy } location /img/ { try_files $uri, @proxy } However, there is nothing that I can find that will give me, location / { try_files @proxy } How do I get the effect I want?

• Nginx: Rewriting directory path to file

  - by Doug

  I'm a little new to Nginx here so bear with me - I want to rewrite a url like foo.bar.com/newfoo?limit=30 to foo.bar.com/newfoo.php?limit=30. Seems pretty simple to do it something like this rewrite ^([a-z]+)(.*)$ $1.php$2 last; The part that I am confused about is where to put it - I've tried my hand at a some location directives but I'm doing it wrong. Here's my existing virtual host config, where should I implement my rewrite? server { listen 80; listen [::]:80; server_name foo.bar.com; root /home/foo; index index.php index.html index.htm; location / { try_files $uri $uri/ /index.html; } location /doc/ { alias /usr/share/doc/; autoindex on; allow 127.0.0.1; deny all; } location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass unix:/tmp/php5-fpm.sock; fastcgi_index index.php; } } Thanks!

• How i can setup a nginx cache strategy that first try amazon s3, then memcache and do a fallback on miss?

  - by Tim

  i have a large site with lot of pages that almost never change, right now i am using two memcache servers (amazon elasticache), but this its really expensive. Thats why for this files that barely never change i want to upload them to amazon s3 and shutdown 1 memcache server. Here is my conf; location ~ /longterm/(.*){ proxy_pass http://amazonS3bucket; proxy_intercept_errors on; proxy_next_upstream http_404; error_page 404 503 = @fallback_memcached } location @fallback_memcache { set $memcached_key $uri; memcached_pass name:11211; error_page 404 @fallback; } location @fallback { try_files $uri $uri/index.html } I dont know why but the config doesnt work on the final fallback; if i got an amazon S3 hit it works, if i got an amazon S3 miss and a memcache hit it works, but if i got an amazon S3 miss then a memcache miss when it try to resolve the las fallback it fails. I am also thinking in use the amazon s3 fuse http://code.google.com/p/s3fs/ instead of the proxy pass i think it would be easier for implement, i would also be less performant?

• How can I load style resources from a dynamically loaded Silverlight application (XAP)?

  - by Tom

  I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ... '' #... wCli = New WebClient AddHandler wCli.OpenReadCompleted, AddressOf OpenXAPCompleted wCli.OpenReadAsync(New Uri("MyTest.xap", UriKind.Relative)) '' #... '' #Here's the sub that's called when openread is completed '' #... Private Sub OpenXAPCompleted(ByVal sender As Object, ByVal e As System.Net.OpenReadCompletedEventArgs) Dim sManifest As String = New StreamReader(Application.GetResourceStream(New StreamResourceInfo(e.Result, Nothing), New Uri("AppManifest.xaml", UriKind.Relative)).Stream).ReadToEnd Dim deploymentRoot As XElement = XDocument.Parse(sManifest).Root Dim deploymentParts As List(Of XElement) = _ (From assemblyParts In deploymentRoot.Elements().Elements() Select assemblyParts).ToList() Dim oAssembly As Assembly = Nothing For Each xElement As XElement In deploymentParts Dim asmPart As AssemblyPart = New AssemblyPart() Dim source As String = xElement.Attribute("Source").Value Dim sInfo As StreamResourceInfo = Application.GetResourceStream(New StreamResourceInfo(e.Result, "application/binary"), New Uri(source, UriKind.Relative)) If source = "MyTest.dll" Then oAssembly = asmPart.Load(sInfo.Stream) Else asmPart.Load(sInfo.Stream) End If Next Dim t As Type() = oAssembly.GetTypes() Dim AppClass = (From parts In t Where parts.FullName.EndsWith(".App") Select parts).SingleOrDefault() Dim mykeys As Array If Not AppClass Is Nothing Then Dim a As Application = DirectCast(oAssembly.CreateInstance(AppClass.FullName), Application) For Each strKey As String In a.Resources.Keys If Not Application.Current.Resources.Contains(strKey) Then Application.Current.Resources.Add(strKey, a.Resources(strKey)) End If Next End If Dim objectType As Type = oAssembly.GetType("MyTest.MainPage") Dim ouiel = Activator.CreateInstance(objectType) Dim myData As UIElement = DirectCast(ouiel, UIElement) Me.splMain.Children.Add(myData) Me.splMain.UpdateLayout() End Sub '' #...

• Change URL of WebBrowser in C#

  - by Sean

  I am designing a simple application using c# and it has a web browser in it. I need to either (preferably) refresh the page that is currently inside the broswer, or navigate to a "new" url. I tried Browser.Url = new Uri("http://www.pandora.com/"); but I get an error when I try to compile it. Error 1 Cannot implicitly convert type 'string' to 'System.Uri' c:\users\sean\documents\visual studio 2010\Projects\Pandora\Pandora\Form1.cs 51 27 Pandora What am I doing wrong?

• Retrieve EF4 POCOs using WCF REST services starter kit

  - by muruge

  I am using WCF REST service (GET method) to retrieve my EF4 POCOs. The service seem to work just fine. When I query the uri in my browser I get the results as expected. In my client application I am trying to use WCF REST Starter Kit's HTTPExtension method - ReadAsDataContract() to convert the result back into my POCO. This works fine when the POCO's navigation property is a single object of related POCO. The problem is when the navigation property is a collection of related POCOs. The ReadAsDataContract() method throws an exception with message "Object reference not set to an instance of an object." Below are my POCOs. [DataContract(Namespace = "", Name = "Trip")] public class Trip { [DataMember(Order = 1)] public virtual int TripID { get; set; } [DataMember(Order = 2)] public virtual int RegionID { get; set; } [DataMember(Order = 3)] public virtual System.DateTime BookingDate { get; set; } [DataMember(Order = 4)] public virtual Region Region { // removed for brevity } } [DataContract(Namespace = "", Name = "Region")] public class Region { [DataMember(Order = 1)] public virtual int RegionID { get; set; } [DataMember(Order = 2)] public virtual string RegionCode { get; set; } [DataMember(Order = 3)] public virtual FixupCollection<Trip> Trips { // removed for brevity } } [CollectionDataContract(Namespace = "", Name = "{0}s", ItemName = "{0}")] [Serializable] public class FixupCollection<T> : ObservableCollection<T> { protected override void ClearItems() { new List<T>(this).ForEach(t => Remove(t)); } protected override void InsertItem(int index, T item) { if (!this.Contains(item)) { base.InsertItem(index, item); } } } And this is how I am trying retrieve a Region POCO. static void GetRegion() { string uri = "http://localhost:8080/TripService/Regions?id=1"; HttpClient client = new HttpClient(uri); using (HttpResponseMessage response = client.Get(uri)) { Region region; response.EnsureStatusIsSuccessful(); try { region = response.Content.ReadAsDataContract<Region>(); // this line throws exception because Region returns a collection of related trips Console.WriteLine(region.RegionName); } catch (Exception ex) { Console.WriteLine(ex.Message); } } } Would appreciate any pointers.

• Enumerate registered namespaces of a PHP DOMDocument object

  - by zneak

  Hello world, For one of my projects, I'm using the DOMDocument class to load and manipulate XML documents. I'd need to retrieve every namespace used in the document; however, I can't find how I'd do that. The DOMDocument class has methods to get the namespace prefix of an URI or the URI of a namespace prefix, but I've seen nothing to actually enumerate registered namespaces. The SimpleXML library has a getNamespaces() method for that. Is there an equivalent for DOMDocument?

• Rewrite Url with apache2

  Hi, I'm experimenting with CodeIgniter PHP framework, this framework works like: http://localhost:7777/~dhalsim/ci/index.php/blog So, I tried to remove index.php part from there. So far I do these: make $config['index_page'] = "index.php"; to $config['index_page'] = ""; make $config['uri_protocol'] = "REQUEST_URI"; from $config['uri_protocol'] = "AUTO"; enable apache mod_rewrite by "a2enmod rewrite" put a .htaccess file to /ci directory: RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php/$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?/$1 [L] And of course restart apache server Here is my apache logs with these configurations: 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] strip per-dir prefix: /home/dhalsim/public_html/ci/blog -> blog 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] applying pattern '^(.*)$' to uri 'blog' 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (4) [perdir /home/dhalsim/public_html/ci/] RewriteCond: input='/~dhalsim/ci/blog' pattern='^system.*' => not-matched 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] strip per-dir prefix: /home/dhalsim/public_html/ci/blog -> blog 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] applying pattern '^(.*)$' to uri 'blog' 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (4) [perdir /home/dhalsim/public_html/ci/] RewriteCond: input='/home/dhalsim/public_html/ci/blog' pattern='!-f' => matched 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (4) [perdir /home/dhalsim/public_html/ci/] RewriteCond: input='/home/dhalsim/public_html/ci/blog' pattern='!-d' => matched 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (2) [perdir /home/dhalsim/public_html/ci/] rewrite 'blog' -> 'index.php?/blog' 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) split uri=index.php?/blog -> uri=index.php, args=/blog 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (3) [perdir /home/dhalsim/public_html/ci/] add per-dir prefix: index.php -> /home/dhalsim/public_html/ci/index.php 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (2) [perdir /home/dhalsim/public_html/ci/] trying to replace prefix /home/dhalsim/public_html/ci/ with / 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (5) strip matching prefix: /home/dhalsim/public_html/ci/index.php -> index.php 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (4) add subst prefix: index.php -> /index.php 127.0.0.1 - - [17/Jul/2009:02:21:41 +0300] [localhost/sid#7f48e8ad2968][rid#7f48e8e634c8/initial] (1) [perdir /home/dhalsim/public_html/ci/] internal redirect with /index.php [INTERNAL REDIRECT] Here is the result in Firefox: 404 Not Found: The requested URL /index.php was not found on this server.

• launching mapview from main activity (button)

  - by arc

  Hi all. Going round in circles here i think. I have an activity called Locate; public class Locate extends Activity { public static String lat; public static String lon; public static String number; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.locate); final Button buttonMaps = (Button) findViewById(R.id.ButtonMaps); buttonMaps.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); try { Intent i = new Intent(getBaseContext(), displayMap.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } catch (ActivityNotFoundException e) { Toast.makeText(getBaseContext(), "Activity Not Found", Toast.LENGTH_SHORT).show(); } }}); // Toast.makeText(getBaseContext(), "lat: " + lat + " long: " + lon + " from: " + testname, Toast.LENGTH_LONG).show(); } If I make the displayMap class into a normal Activity, and just have display a toast message confirming it has loaded - then it works fine. If i do this though; public class displayMap extends MapActivity { /** Called when the activity is first created. */ public void onCreate() { setContentView(R.layout.displaymap); Toast.makeText(getBaseContext(), "Display Map", Toast.LENGTH_SHORT).show(); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } Then as soon as I click the Button, I get a force close. I have the correct 'uses-library' tag in my manifest; <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> I don't get what it just force closes everytime i try and load it. If I make this my onClick handler then it will fire up a working googlemaps/default mapview public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); Uri uri=Uri.parse("geo:"+Locate.lat+","+Locate.lon); StartActivity(new Intent(Intent.ACTION_VIEW, uri)); } But that is not what I am trying to do, I want my own - so that I can add overlays etc to it. But it does prove that the permission are set correctly and that the lib is there. The logcat error when the app FCs is a Unexpected DEX error. Can anyone point in the right direction here?
