this.BackColor = colorDialog1.Color;
The main Form disapears and I have to go into the control bar at the bottom to find it.

How do I use ToolTip after I placed one onto the form as a non-visual component? How do I link it to a component & choose the text on the tip?

1) That's odd.

2) You should see a tooltip property on each control on the form.

1. Very very odd.

2. See below code. You can add this in the Form_Load Event.

toolTip1.AutoPopDelay = 5000;
toolTip1.InitialDelay = 500;
toolTip1.ReshowDelay = 500;
toolTip1.ShowAlways = true;
toolTip1.SetToolTip(this.btnRun, "Run");
toolTip1.SetToolTip(this.btnSelectDirToSave, "Select Output Directory");
toolTip1.SetToolTip(this.btnSelectTxtFile, "Select File to Process");

Hope this helps

Where can I see example of how to so.
I want that the mouse image will change to like in the design options in the .NET.

All you need to do is handle MouseDown, MouseUp, MouseMove and Paint events. Use Cursor property to change the cursor the way you like.

A bit of Googling will definitely give you some examples.

Check if web-frame in webclient is done loading

Hello.
I have a application with a webclient. In that webclient I am loading a homepage with about 5 frames, but one of the frames are refreshing constantly each 30second.
That gives me problem when I want to use the source from another frame - because when I use IsBusy and it is refreshing the frame with constantly refreshing while I am navigating another frame, does the application think that frame is done navigating too, and then I of course get an error.
It happens very often, and stops the whole program.

So is there any way only to check one frame if it is done loading ?

Hope your guys can help me out.

How to use Combo box in C#

dotnetkoders15-May-09 21:00

Hi All,
I have a class Class1. In Class1 constructor I am calling InitializeComponent().Which will be used to add controls to form at runtime. I have one more method Initialize(). In this Initialize() I am filling the value for the combo box.
My problem is the value is not updated in combo box.

Could any one help me to solve this issue.

Code snippet:
<pre>
Public Class1()
{
InitializeComponent();
}
Public void Intialize()
{
string[] employees = new string[]{"Hamilton, David", "Hensien, Kari"};
SampleComboBox.Items.AddRange(employee);
SampleComboBox.SelectedItem=employee[0];
SampleComboBox.SelectedIndexChanged += new System.EventHandler(this.SampleComboBox_SelectedIndexChanged);
}

This code is present in Designer.cs

Private InitializeComponent()
{
this.SampleComboBox.DropDownStyle = System.Windows.Forms.ComboBoxStyle.DropDownList;
this.SampleComboBox.DropDownWidth = 97;
this.SampleComboBox.FormattingEnabled = true;
this.SampleComboBox.Location = new System.Drawing.Point(84, 16);
this.SampleComboBox.Name = "SampleComboBox";
this.SampleComboBox.Size = new System.Drawing.Size(91, 21);
this.SampleComboBox.TabIndex = 2;

this.Controls.Add(this.SampleComboBox);
this.Name = "SampleApp";
this.Size = new System.Drawing.Size(190, 51);
this.ResumeLayout(false);
}
private System.Windows.Forms.ComboBox SampleComboBox;
</pre>

Thanks,
Anandi

You need to call the Initialize method after InitializeComponent

Public Class1()
{
    InitializeComponent();
    Initialize();
}

Don't get your question.

Generally you can validate a textbox as

if(String.IsNullOrEmpty(textBox1.Text))
MessageBox.Show("TextBox is empty");

You can also use the Validate event.

Another option is ErrorProvider.
