    <p>I have a dotnet script which is for encryption and decryption. I have to pass the parameters for the setvalues function in installshield. How can I achieve this? Dotnet code is as follows. I have the assembly (.dll) file.</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Configuration; using System.Security; using System.Xml; using System.Collections.Specialized; namespace EncryptionDecryption { public class EncrptionHelper { #region Member variables static byte[] entropy = { 0, 8, 2, 3, 5 }; #endregion #region Public Methods public static void SetValue(string configFilePathName, string appSettingKey, string appSettingValue) { appSettingValue = EncryptString(ToSecureString(appSettingValue)); SetSetting(appSettingKey, appSettingValue, configFilePathName); } public static string GetValue(string configFilePathName, string appSettingKey) { string value = GetSetting(appSettingKey, configFilePathName); value = ToInsecureString( DecryptString(value)); return value; } #endregion #region Private Methods private static bool SetSetting(string Key, string Value, string configFilePath) { bool result = false; try { // System.Configuration.Configuration config = ConfigurationManager.OpenExeConfiguration(configFilePath); // config.AppSettings.File = configFilePath; // config.AppSettings.Settings[Key].Value = Value; // config.Save(ConfigurationSaveMode.Modified); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(configFilePath); xmlDoc.SelectSingleNode("//appSettings/add[@key='" + Key +"']").Attributes["value"].Value = Value; xmlDoc.Save(configFilePath); ConfigurationManager.RefreshSection("appSettings"); result = true; } finally { } return result; } private static string GetSetting(string Key, string configFilePath) { string result = null; try { XmlDocument appSettingsDoc = new XmlDocument(); appSettingsDoc.Load(configFilePath); XmlNode node = appSettingsDoc.SelectSingleNode("//appSettings"); XmlElement value = (XmlElement)node.SelectSingleNode(string.Format("//add[@key='" + Key + "']")); result = (value.GetAttribute("value").ToString()); } finally { } return result; } private static SecureString ToSecureString(string input) { SecureString secure = new SecureString(); foreach (char c in input) { secure.AppendChar(c); } secure.MakeReadOnly(); return secure; } private static string ToInsecureString(SecureString input) { string returnValue = string.Empty; IntPtr ptr = System.Runtime.InteropServices.Marshal.SecureStringToBSTR(input); try { returnValue = System.Runtime.InteropServices.Marshal.PtrToStringBSTR(ptr); } finally { System.Runtime.InteropServices.Marshal.ZeroFreeBSTR(ptr); } return returnValue; } private static string EncryptString(System.Security.SecureString input) { byte[] encryptedData = System.Security.Cryptography.ProtectedData.Protect( System.Text.Encoding.Unicode.GetBytes(ToInsecureString(input)), entropy, System.Security.Cryptography.DataProtectionScope.CurrentUser); return Convert.ToBase64String(encryptedData); } private static SecureString DecryptString(string encryptedData) { try { byte[] decryptedData = System.Security.Cryptography.ProtectedData.Unprotect( Convert.FromBase64String(encryptedData), entropy, System.Security.Cryptography.DataProtectionScope.CurrentUser); return ToSecureString(System.Text.Encoding.Unicode.GetString(decryptedData)); } catch { return new SecureString(); } } #endregion } } Update: Action start 14:31:36: Encryption.

    1. COIf this is in a Basic MSI project, see http://stackoverflow.com/a/18334804/89999 . For other project types see some of the other answers on that question.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
