Assuming that you have detailed your requirements correctly, and that you can't use a list (for example), you could do it like this (in pseudocode):

declare array of size n

for count = 0, count less than n
  create a new instance of button
  set the text of the button
  add it to the parent control collection (where parent could be a form, a panel, or the like)
end for

Don't forget to set the Location of the Button.

I also tend to put have a Panel or GroupBox to hold such dynamic Controls to separate them from the non-dynamic items.

The solution would be:

public Form1()
       {
           InitializeComponent();

           var buttons = new Button[5];
           for (int i = 1; i < buttons.Length; i++)
           {
               buttons[i] = new Button();
               buttons[i].Text = "[button" + i + "]";
               buttons[i].Location = new Point(0, 25 * i);
           }

           Controls.AddRange(buttons);
       }

obviously you would have to adjust on your formatting. but thats the general idea. hope this helped.

Please note the above code would produce #4 buttons, not #5. The array element at position #0 will be undefined.

If the button's width, which you don't specify, is exactly #25, then they will be equally spaced, and not overlap; but that makes an assumption about a button's default width, which can be affected by whether 'AutoSize is 'true, and the width of the 'Text property content.

And, no, I did not down-vote your post.

best, Bill

I agree with your statement. This was a rough general idea so he could get started. Not a final solution. Please bare that in mind. Thanks though.

It is possible. You're going to need the Google Docs Client[^] to help you though.

Well, as the link includes a .NET client version, I'd say there was a very good chance that it would.

This is what I did and it works:

You have a hidden control calls vertscrollpossition and a panel called panel_contents.

This is the code behind:

private void SetScrollPosition(){
	string script;
	ClientScriptManager CSManager = Page.ClientScript;
	if(!CSManager.IsOnSubmitStatementRegistered(this.GetType(),"SaveScrollPosition")){
		script = "var HiddenField = document.getElementById('" + vertscrollposition.ClientID + "');\n\r";
		script += "var ScrollElement = document.getElementById('" +	panel_contents.ClientID + "');\n\r";
		script += "HiddenField.value = ScrollElement.scrollTop;\n\r";
		CSManager.RegisterOnSubmitStatement(this.GetType(), "SaveScrollPosition",script);
	}									//end if
	if(!CSManager.IsStartupScriptRegistered(this.GetType(),"RetrieveScrollPosition")){
		script = "var HiddenField = document.getElementById('" + vertscrollposition.ClientID + "');\n\r";
		script += "var ScrollElement = document.getElementById('" + panel_contents.ClientID + "');\n\r";
		script += "if(HiddenField.value != '')\n\r";
		script += "{\n\r";
		script += "ScrollElement.scrollTop = HiddenField.value;\n\r";
		script += "}\n\r";
		CSManager.RegisterStartupScript(this.GetType(), "RetrieveScrollPosition",script, true);
	}									//end if
}

This is the aspx code:

<asp:Panel ID="panel_contents" Height="175" Width="800" runat="server" ScrollBars="Vertical" ViewStateMode="Enabled" EnableViewState="True">
</asp:Panel>
<asp:HiddenField ID="vertscrollposition" runat="server" />

Have you tried setting MaintainScrollPositionOnPostback="true" on your page? If that works, that would be the easiest to do.

Hi,

I am trying to connect to mySql using C# but getting this error:

Quote:
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

I have added the port thinking it could solve the issue! but still the same.. here is my connection string:

<add name="SQLdb" connectionString="server=192.168.0.1;port=3306;User Id=root;password=Mxjxaxax0x1;Persist Security Info=True;database=cure"
      providerName="MySql.Data.MySqlClient" />

please help...

Thanks BUT

now this is my connection in the App.config:

<add name="SQLdb"connectionString="server=192.168.0.1;port=3306;Uid=root;Pwd=xxxxxxxxx;database=cure;" providerName="MySql.Data.MySqlClient" />

but I am still getting:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

just one notes:

The same code is working if I run the application on the server itself (using IP not localhost)

What happens if you try to connect to the database using a standard MySQL client? It almost looks like a firewall may be blocking your connection.

SqlConnection in encrypted file

24-Jan-12 5:22

it works when I connect using mySQL client

but the good news..

I figured out the problem...

I just address connection timeout=120

it seems like it's taking time to connect!

anyhow..

thanks...

Re: SqlConnection in encrypted file

23-Jan-12 21:44

Hi,

can anyone guide plz..

I want to save the sqlConnection parameters in an encrypted file so the WinForm application will read the host, database, user name, and password from that file.. The file will be distributed with the application..
