32.28 How can I make sure I don't open a second instance modeless dialog that is already opened from my main form? |
There are a several of ways to do this. Here are a few: |
| textBox1.Text = "This is line 1.\r\nThis is line 2";
|
| // or textBox1.Text = stringvar1 + "\r\n" + stringvar2; |
2) Use the Environment.NewLine property. This property is normally set to "\r\n". |
| textBox1.Text = "This is line 1." + Environment.NewLine + "This is line 2"; |
3) Use the Lines property of the TextBox. Make sure you populate your array before you set the property. |
| string[] arr = new string[2];
|
| arr[0] = "this is line1";
|
| arr[1] = "this is line 2";
|
|
|
| textBox3.Lines = arr; |
