Hi guys,

I have been working on an application in C# and have finally got to the fun stage of creating the help files.

I found the VS Help Integration Toolkit and have installed this and created a simple help 2.0 file with a few html files. The problem is that I now cannot work out how to launch this HxS file in my application.

Any ideas?

Cheers

Hey I would like to control the creation of a dataset instance, when i drag and drop it into the designer.

The current designer add a new instance... like so:

this.dataSet1 = new System.Data.DataSet();

in the "Designer generated code" #region.

How do I change this into something I define... FX:

this.dataSet1 = DataSetSingleton.Instance.MyDataSet;

???

I think I need to make a new type converter but im not sure...

AddNew() and default values

Hello,

I want to add a new row to my dataset, so I use the AddNew() method.
The problem I have is that in my database definition I have defined a default value for some of the fields.

How can I get this default values in my new row?

Thanks

Hi.

The DataColumn class exposes a DefaultValue property that you should be able to use.

Example:

            DataTable table = new DataTable("SomeTable");<br />
            table.Columns.Add("Column1", typeof(string));<br />
            table.Columns.Add("Column2", typeof(string));<br />
<br />
            table.Columns["Column1"].DefaultValue = "Foo";<br />
            table.Columns["Column2"].DefaultValue = "BlahBlah";

If you were to execute the code above, then add a row to the table it creates, the row's Column1 value would be preset to "Foo" and the Column2 value would be "Blah".

Hope this helps,

This is indeed a solution, but I wanted to avoid putting these default values into my program. That's why I've filled in these values while creating my SQL table.
So I was hoping for a trick to get/read these values into the program.

Can I retrieve default values from a database using Stored Procedures?

Thanks

The example I provided was simply to indicate that default values were available at design-time for the System.Data.DataColumn class.

If you want to determine the characteristics of columns in your database at runtime, there are a number of ways to do it. You could use SQL to inspect the system tables in your database directly or you could use something like System.Data.OleDb.OleDbConnection.GetOleDbSchemaTable to retrieve tons of information about your physical database.

For instance, to retrieve column info, you might use (where conn is an OleDbConnection):

DataTable columnInfo = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Columns, new object[4]{null, null, "MyTable", null});

The call uses the OleDbSchemaGuid class to specify the type of database object you're trying to fetch information about, and the object array is a list of restriction values (like a filter) that determines which specific instance(s) of the database object type you want to investigate.

Best of luck.

You should use the CheckedChanged property.

ex:

RadioButton1_CheckedChanged(object sender, System.EventArgs e)
{
   if (RadioButton1.Checked == true)
   {
      TextBox1.Enabled = true;
   }
}

Ah ha... You didn't say you were using it on a WebForm. Smile | :)

Have a look at this[^].

Note that the control does not immediately cause the page to post back to the server by default. You need to set the AutoPostBack property to true for an immediate reaction to it's change in state.

Hope this helps you.

You could use the mouse down event - you can use the MouseEventArgs parameter to test which mouse button was used.

Where did you found that info? The
MSDN topic[^] of the RadioButton lists the Click event and it's also available in the Visual Studio form designer.

Hey!

I have created a Windows Control Library
I have built this and added the dll file to my main project

This workt well, but when i closed and then started upp my main progject again the control was not visible in the form?

And i got the folowing errors (menuPanel1 is my dll control)

C:\ForumProject\ForumClient\ForumClient.cs(324): The variable 'menuPanel1' is either undeclared or was never assigned.

An exception occurred while trying to create an instance of ForumClient.MenuPanel. The exception was "Invalid parameter used.".

But i can run the program and then the control is visible?

I have tryed to rebuild the control and add it to the project, but i get this message when i am draging it to my main form

An exception occured whule trying to creat an instance of Forum.MenuPane. Exception was "Invalid parameter used.".

My construkter in the control looks like this

		public MenuPanel()<br />
		{<br />
			// This call is required by the Windows.Forms Form Designer.<br />
			InitializeComponent();<br />
<br />
		}

and The automated code to create it looks like this

private MenuPanel menuPanel1;<br />
<br />
		private void InitializeComponent()<br />
		{<br />
                        this.menuPanel1 = new MenuPanel();<br />

Hey

I am developing a simple Client program and i have made an Windows Control Library(DLL file) that i am adding to my client.

AnyWay This Control contains a Bitmap picture that is 272x600 wit 3 buttons on it with is 202x36, all is BMP.

When moving other Windows ower my Client(where the Bitmaps is) thay are updated wary slow? Is there any easy way to make it go faster?

I am loading all pictures in to Bitmaps object on startup and then adds them to the right controls.

Best Regards
Jimmy

Maybe enabling of double-buffering improves your situation.

i have added the following line ni bouth the MainClient(project) and Windows Control Libraray(the control) in theres cunstructer:

SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.DoubleBuffer | ControlStyles.UserPaint, true);

But this dosent do anything. When i am moving an other window ower the bitmaps the window that i am moving over is lagging on the bitmap creating alot of windows, and it take about 1 sec before the bitmap is updated and the Window crap on the bitmap is over painted.

Try calling the method inside of an event handler for the Load event and add a call to the UpdateStyles method, which forces the assigned styles to be reapplied to the control.

Do you mean that you could call this in the contructer of my Main project

SetStyle(ControlStyles.AllPaintingInWmPaint | ControlStyles.DoubleBuffer | ControlStyles.UserPaint, true);<br />
this.UpdateStyles();

This does not changes Frown | :(

Or how do you mean i shold add it?
