I have a RichTextBox control with text and images. How can I get the size of the occupied space? GetPositionFromCharIndex doesn't work with the image. The alignment could be left center or right.
Forgot to mentions compiling for .NET 2.0.
I have a main window in my project, and numerous other child widows inside the main.I have noticed that. When I open the main window occupies 1500K of memory, when open one child window then adds in occupied memory 6000K.When I open the second window doing the same. When I close the two child windows the occupied memory is not released.So What I want is to release the occupied memory when ever I close child windows.How I can do that? with some code example in vb.net if it is possible.This problem often sawing in the computers on the Local NET not in my computer (developer computer which has the SQL server on it).
View 7 RepliesHow would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then
Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength)
Textbox3.AppendText("a")
End If
Btw: after i finish this step my project will be finished!

View 2 RepliesI am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

I would like to get the width of some text drawn by GDI+ in an Integer so that I can adjust the position of a cursor.
I used:
"lCursor = g.MeasureString(vInputText, Font)"
In which 'lCursor' is the offset for the original location of the cursor. But apparently the output of MeasureString is not integer and can't even parse it to integer.

I have a timer that start when Space is pressed. To avoid an accidental start by hitting space twice, I put in the .Sleep, but if I press the Space more than once it starts the timer anyway.
How it works: Space: Start timer (button4 is focussed), (button3.focus)
Space: Stop timer, display msgbox with result
Threadin.Thread.Sleep(750)Button4.Enabled = True Button4.Focus()
I have a program in VB.net that uses a 3D array:
Private gridList(10, 900, 900) As GridElement
Now, I just used a Memory Profiler on it (because my application is having some major leak issues or something) and apparently, this array (containing at the moment of testing 0-30 elements at one time) is using 94% of the memory currently in use by my application. Even when it is empty it takes up huge amounts of memory.
My only assumption is that even empty arrays take up space! This puts a major blow into my plans!
My Question:
Is there any alternative to this that allows me to still have the same abilities to map i.g. I've been using it like this:
Dim cGE as GridElement = gridList(3, 5, 7)
but doesn't hog up so much memory for things that aren't using memory?
How can I add white space around the image?.
