Hello,

Is there a way of placing a groove line on the Form? I tried to look
something up in Customization of a ToolBox, but to no avail.

Thank you.

hey Zaboboa,

To draw a line in c#, you need to use a label.

//
// label1
//
this.label1.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
this.label1.Location = new System.Drawing.Point(44, 68);
this.label1.Name = "label1";
this.label1.Size = new System.Drawing.Size(100, 2);
this.label1.TabIndex = 0;
this.label1.Text = "label1";

Or if you really want, you can make a user control that will draw the line(s).

Add forms to a container

Does anybody know of a way to add a form to a container?

For example adding a form as a control of another form, but not using IsMdiContainer?

Set the TopLevel property of your "child" form to false. Then you can add it to any Controls container you want.

Remoting disconnections

If I run my remoting client, and during run time I temporarily lose my connection to the network, how can I continue on using remoting?

For example,

// connect to the server object
ServerObj theServerObject = RemotingServices.Connect("tcp://.../obj.rem");

// happily call a method on it
theServerObject.DoSomething(); // works fine

// pretend we get disconnected
LanConnection.Zap();

// pretend we reconnect
LanConnection.ReEstablish();

// try to call a method
theServerObject.DoSomething(); // fails!

I've been banging my head against a wall over the last 2 days trying to figure this one out. Anyone have insight into why this is happening, or how to 'reconnect' to my server object? Even the least bit of info would be greatly appreciated.

In my projects I'm using Activator.CreateInstance() to get my server objects.
One of them is explicitely marshalled in a server application, the other one is a SingleCall CAO.

I didn't experience any problems like this so far. When my server application is shut down, then all calls will naturally fail, but simply restarting the server brings everything back to normal, i.e. my client programs work as if the server never was gone.

Perhaps RemotingServices.Connect does something different than Activator.CreateInstance()...
Can you confirm that using Activator.CreateInstance() gives the same effect?

I think that you are miss understanding what I want. I want my datagrid to spread out the columns across the top of the grid depending on the number of tables.

Currently my code is setting a fix size but I cannot even get that working. Do you have any suggestions?

<br />
			GridColumnStylesCollection gcsColl = StudenDataGrid.TableStyles["Student"].GridColumnStyles;<br />
			for (int i = 0; i<gcsColl.Count; i++)<br />
			{<br />
				if (gcsColl[i].GetType() == typeof(DataGridTextBoxColumn))<br />
				{<br />
					DataGridTextBoxColumn textColumn = (DataGridTextBoxColumn)gcsColl[i];<br />
					textColumn.Width = 150;<br />
				}<br />
			}<br />
<br />

Hey ,

You want to spread the columns depending on the number of tables or columns? I think I did not understand your question. Assuming you want to spread the columns depending on the number of columns implement AdjustColumnsWidth as. Hope this helps

private void AdjustColumnsWidth()
{
this.isColumnWidthAdjusting = true;
int verticalScrollBarWidth = this.globalEntitySearchGrid.VerticalScrollWidth;
int currentWidth =
this.dataGridTextBoxColumnExConjunction.Width +
this.dataGridTextBoxColumnExEntity.Width +
this.dataGridTextBoxColumnExOperator.Width +
this.dataGridTextBoxColumnExValue.Width +
DELTAFACTOR + this.gridTableStyle.RowHeaderWidth;
int gridClientWith = this.globalEntitySearchGrid.ClientSize.Width - verticalScrollBarWidth;

if (currentWidth > gridClientWith)
{
int delta = currentWidth - gridClientWith;
this.UnWireResizeEvents();
this.dataGridTextBoxColumnExConjunction.Width = this.dataGridTextBoxColumnExConjunction.Width - delta / 4;
this.dataGridTextBoxColumnExEntity.Width = this.dataGridTextBoxColumnExEntity.Width - delta / 4;
this.dataGridTextBoxColumnExOperator.Width = this.dataGridTextBoxColumnExOperator.Width - delta / 4;
this.dataGridTextBoxColumnExValue.Width = this.dataGridTextBoxColumnExValue.Width - delta / 4;
this.RefreshGrid();
this.WireUpResizeEvents();
this.AdjustDynamicControls();
}
else if (currentWidth < gridClientWith)
{
int delta = gridClientWith - currentWidth;
this.UnWireResizeEvents();
this.dataGridTextBoxColumnExConjunction.Width = this.dataGridTextBoxColumnExConjunction.Width + delta / 4;
this.dataGridTextBoxColumnExEntity.Width = this.dataGridTextBoxColumnExEntity.Width + delta / 4;
this.dataGridTextBoxColumnExOperator.Width = this.dataGridTextBoxColumnExOperator.Width + delta / 4;
this.dataGridTextBoxColumnExValue.Width = this.dataGridTextBoxColumnExValue.Width + delta / 4;
this.RefreshGrid();
this.WireUpResizeEvents();
this.AdjustDynamicControls();
}
this.isColumnWidthAdjusting = false;
}

Or this would work too:

			//Put Grid Autosize code here<br />
			DataGridTableStyle style = new DataGridTableStyle();<br />
			style.MappingName = dataTable.TableName;<br />
			foreach (DataColumn column in dataTable.Columns)<br />
			{<br />
				DataGridTextBoxColumn gridColumn = new DataGridTextBoxColumn();<br />
				gridColumn.MappingName = column.ColumnName;<br />
				gridColumn.HeaderText = column.ColumnName;<br />
				gridColumn.Width = StudenDataGrid.Size.Width / accessDataSet.Tables["Student"].Columns.Count;<br />
				style.RowHeadersVisible = false;<br />
				<br />
				style.GridColumnStyles.Add(gridColumn);<br />
			}<br />
<br />
			StudenDataGrid.TableStyles.Add(style);<br />
			this.StudenDataGrid.DataSource = accessDataSet.Tables["Student"];<br />

This will autosize the column headers according to the number of columns you have in your dataset.

Thanks for the help.

WHAT?? If you didn't change anything, there won't be any differences.

Or, like I said, WHAT? I don't understand what your asking. "Difference DLL"???

hi to all,

how can i disable a text box without changing the forecolor to gray.
what i want is to disable the text box and to keep the forecolor to black.

i don't want to use the readonly property because the back color is still white.

best regards and thanks in advance

Those are your only options while still using a TextBox.

A little trick I've seen used before is to create equivilent label controls, set them up to look like the textboxes, and put them behind their textbox counterparts. Then when the textboxes needed to become ReadOnly without the readonly look, they just set the TextBox.Visible property to false.

I think this is purely controlled by Windows and may be a little by CLR. I don't think there would be a setting to this effect.
