I am creating a application that store basic database connection info like host,user, password

  • 0

I am creating a application that store basic database connection info like host,user, password and default database name in application settings using User Scope.

I am using .net 3.5 with Visual Studio 2008

I put 4 text boxes in a user control and bound their text property to the application settings individual properties. 

//          // textBox_database         //          this.textBox_database.Location = new System.Drawing.Point(103, 101);         this.textBox_database.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);         this.textBox_database.Name = 'textBox_database';         this.textBox_database.Size = new System.Drawing.Size(255, 27);         this.textBox_database.TabIndex = 5;         this.textBox_database.Text = global::PHP_Code_Generator_2.Properties.Settings.Default.mysql_database;         //          // textBox_password         //          this.textBox_password.Location = new System.Drawing.Point(103, 69);         this.textBox_password.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);         this.textBox_password.Name = 'textBox_password';         this.textBox_password.Size = new System.Drawing.Size(255, 27);         this.textBox_password.TabIndex = 4;         this.textBox_password.Text = global::PHP_Code_Generator_2.Properties.Settings.Default.mysql_password;         this.textBox_password.UseSystemPasswordChar = true;         //          // textBox_user         //          this.textBox_user.Location = new System.Drawing.Point(103, 37);         this.textBox_user.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);         this.textBox_user.Name = 'textBox_user';         this.textBox_user.Size = new System.Drawing.Size(255, 27);         this.textBox_user.TabIndex = 7;         this.textBox_user.Text = global::PHP_Code_Generator_2.Properties.Settings.Default.mysql_user;         //          // textBox_server         //          this.textBox_server.Location = new System.Drawing.Point(103, 5);         this.textBox_server.Margin = new System.Windows.Forms.Padding(3, 4, 3, 4);         this.textBox_server.Name = 'textBox_server';         this.textBox_server.Size = new System.Drawing.Size(255, 27);         this.textBox_server.TabIndex = 6;         this.textBox_server.Text = global::PHP_Code_Generator_2.Properties.Settings.Default.mysql_server;

these text boxes will get user data from users to set their own database info. i have a button that saves the modified info back to the settings file

private void button_save_Click(object sender, EventArgs e) {    Properties.Settings.Default.Save(); }

but the design is not being saved. any help anyone?

regards, Anjan

To Cyril: Yes i had the code to assign modified value in properties, but then even the scope was set to ‘User’ it said readonly. So i removed the property assignment codes. now i brought the code back and restarted VS, it works perfect now 😀 silly me, i should have try this old procedure before. Thank you Cyril.

  1. Hmm… I remember having the same problem a few months ago in one of my projects. Unfortunately I don’t recall how I solved it.

    Some checks…

    1. Try setting the property scope to User in the Project Properties.
    2. In the code you’ve listed I don’t see where you set the property (only see you retrieving the property). Where have you set it?
