Amazon.Runtime.AmazonServiceException: Unable To Find Credentials


Answer :

Create a credentials file at any path where you can access this path from web service application e.g. C:\awsfile\credentials but remember don't give any extension this file File should contains following data.

[default] aws_access_key_id=[your_access_key] aws_secret_access_key=[your_secret_key]

After this you need to set the path in appsetting tag in the Web.config file:

<appSettings> <add key="AWSProfilesLocation" value="C:\awsfile\credentials" /> <add key="AWSRegion" value="us-east-1" /> </appSettings>

In AWS Explorer for Visual Studio you can create user profiles that give you different permissions on AWS, then you can choose which profile you want to use in AWS Explorer. These profiles are available only to your Windows user account, if anyone else uses your computer then they will have to create their own profiles. Any software that you run under your user account can also use these profiles.

If you don't configure your application to use a specific profile then it will use the default profile.

This problem occurs because IIS runs under a different user account than the one you are logged into, and therefore does not have access to your AWS profiles.

There are several ways to tell your application which AWS profile to use when it runs (see http://docs.aws.amazon.com/sdk-for-net/v2/developer-guide/net-dg-config-creds.html). The simplest option for developers is to create a credentials file and reference that file from web.config. For example if you create a file called C:\aws\credentials you can tell your application to use profile2 from this credentials file by adding this to your web.config file.

<configuration>    <configSections>     <section name="aws" type="Amazon.AWSSection, AWSSDK.Core" />   </configSections>    <aws      region="us-east-1"      profileName="profile2"     profilesLocation="C:\aws\credentials" />  </configuration>

The content of the credentials file should be similar to this:

[profile1] aws_access_key_id = {accessKey} aws_secret_access_key = {secretKey}  [profile2] aws_access_key_id = {accessKey} aws_secret_access_key = {secretKey}

To get an access key and a secret key go to the AWS IAM console at https://console.aws.amazon.com/iam/home?region=us-east-1#/users choose the user you want your application to run as, then click on the "Security Credentials" tab then click the "Create Access Key" button.

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
