There is no way I could trump that.

FYI: the suite you call diamonds, has two names in Dutch; the official one would translate to window glass, the more popular one to cookies.

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

exception in datagridview

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.

MQ Client Error

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

Stacktrace: at IBM.WMQ.MQClient.MQCONNX(String qMgrName, MQCNO& mqcno, Int32& pHconn, Int32& pCompCode, Int32& pReason)

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!

Problem with changing connection string that saved in app.config

Re: Problem with changing connection string that saved in app.config

8-Oct-09 6:13

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());
   ...........
   .......
}

i want to save my connection string in app.config to save this state in future use. next time it must use the saved settings which user set.

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.

my problem is that i can't store my settings in app.config file. it's not persistence.

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.

All the best
