I do acutally have one for each suit, if that matters on your suggetions. I do have it working however.

as the four suits are mutually exclusive it would make sense to use a 4-way enum, which works the same in C# as in VB.NET

You add it to whatever the datasource is, not the grid.

I am debugging C# code that utilizes the Websphere MQ Client 5.3. I have the client installed on my PC and Im running under a local account. when the code gets to where I'm initializing the MQManager I get the following:

Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

Here is the code that is bombing:

MQEnvironment.Hostname = HostName;
MQEnvironment.Channel = Channel;
MQEnvironment.Port = Port;
mqQMgr = new MQQueueManager(QueueManager);

Source: amqmdnet

Any help would be greatly appreciated!

Thanks so much for the response. I figured out what the issues was. The entire PC needed to be re-imaged. The registry along with the GAC was total fried. Rather than going thru one by one and figuring out what dlls need register I found it easier to just re image the PC. But thanks again!

Hi i want to change connection string that saved in app.config (which created in visual studio wizard dialog).
i changed some Settings.Designer.cs code which described in this thread[^] to make that editable. that's works good when i change it at runTime and load it again, but when i exit from my app and look at my saved properties, it's again backed to earlier settings (before my edit).
what's the problem and how to solve this ?
thanks

here is my Settings.Designer.cs code (my modification code is bold) :

[global::System.Configuration.UserScopedSettingAttribute()]
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.Configuration.SpecialSettingAttribute(global::System.Configuration.SpecialSetting.ConnectionString)]
        //[global::System.Configuration.DefaultSettingValueAttribute("Data Source=.;Initial Catalog=mehr;Integrated Security=True")]
        public string mehrConnectionString {
            get {
                return ((string)(this["mehrConnectionString"]));
            }
            set
            {
                this["mehrConnectionString"] = value;
            }
        }

        [global::System.Configuration.UserScopedSettingAttribute()]
        [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
        [global::System.Configuration.SpecialSettingAttribute(global::System.Configuration.SpecialSetting.ConnectionString)]
        //[global::System.Configuration.DefaultSettingValueAttribute("Data Source=.;Initial Catalog=mehr;Integrated Security=True")]
        public string mehrConnectionString1 {
            get {
                return ((string)(this["mehrConnectionString1"]));
            }
            set
            {
                this["mehrConnectionString1"] = value;
            }
        }

here is my code to save in app.config :

Properties.Settings.Default.serverName = this.txtServer.Text;
                    Properties.Settings.Default.userName = this.txtUser.Text;
                    Properties.Settings.Default.password = this.txtPass.Text;

                    if (this.radioLocal.Checked)
                    {
                        Properties.Settings.Default.network = false;
                        Properties.Settings.Default.mehrConnectionString = string.Format("Data Source={0};Initial Catalog=mehr;Integrated Security=True", this.txtServer.Text);
                        Properties.Settings.Default.mehrConnectionString1 = string.Format("Data Source={0};Initial Catalog=mehr;Integrated Security=True", this.txtServer.Text);
                    }
                    else
                    {
                        Properties.Settings.Default.network = true;
                        Properties.Settings.Default.mehrConnectionString = string.Format("Data Source={0};Initial Catalog=mehr;User Id={1};Password={2};", this.txtServer.Text, this.txtUser.Text, this.txtPass.Text);
                        Properties.Settings.Default.mehrConnectionString1 = string.Format("Data Source={0};Initial Catalog=mehr;User Id={1};Password={2};", this.txtServer.Text, this.txtUser.Text, this.txtPass.Text);
                    }
                    Properties.Settings.Default.Save();

Probably you are loading the app.config several times, why dont you use a Hashtable for managing multiple connectionstring
Example:

Hashtable ObjHashtable   = new Hashtable();

ObjHashtable.Add("Key1", "Data Source= source_1 ;Initial Catalog= DatabaseName_1;User ID=id;Password=pwd;");
ObjHashtable.Add("Key2", "Data Source= source_2 ;Initial Catalog= DatabaseName_2;User ID=id;Password=pwd;");

You just need to load the Hashtable only one time...........

public SqlDataReader Example(string strSql, string strKey)
{
   ObjSqlConnection = new SqlConnection(ObjHashtable[strKey].ToString());
   ...........
   .......
}

You are most welcome....... Smile | :)

Absolutely you save your connectionString in your app.config.

My point of view was:

1.     Read your config file
2.     Fill the HasTable
3.     Use the HasTable runtime so that you not need to invoke config file several times.

I am looking into a simular issue and although, I am no expert, I think app.config is used in design time and [appname].exe.config is for release and where the changes need to be made... anyone, please correct me if I'm wrong on this.

Can you provide a correct subject.

Passing a Form's control to a routine in another class as a variable

I have a simple program. It has one Form called frmMain, and another Class called Poker. I have the following snippit routine below. The name 'Color' does not exist in this context. What do I need to do to make this work?

public void Results(Label lbl_1)
{
frmMain Form1 = new frmMain();

lbl_1.ForeColor = Color.Yellow;
Form1.lblWinnings.Text = "100";
}
