Show Whitespace In A Textbox / Richtextbox?
Jun 27, 2011
There is an option in Visual Studio (since as far back as I can remember) that allows you to see "Whitespace" in your code. This is often seen in file differential viewers as well.
I'm wondering if anyone knows how this can be accomplished in VB.net (or any other way) so that i could use a similar type of display option in my software.
I have not yet tried to do this but my only first thoughts would be to override the "paint" of the textbox to actually add the little tab "arrows" and space "dots" manually via GDI, or create a texbox control from scratch. Seems to me there could be an easier way to do this.

I have an ASP.Net 2.0 textbox which I need to be validated as having some content, but where whitespace alone is valid input. A required field validator seems to reject a pure whitespace input as invalid. A regular expression validator won't fire at all on empty content. Is there a simpler way round this than using a custom validator control?

i'm working on a project after returning to coding after four years off and i'm a bit rusty. My problem is that i'm creating a login page and i've got a few people with two last names. in the login box they would put their full name but in the database they have spaces between them. An example would be the name mighel santa anna.

I need to split a string at all whitespace, it should ONLY contain the words themselves. How can I do this in vb.net? Tabs, Newlines, etc. must all be split! This has been bugging me for quite a while now, as my syntax highlighter I made completely ignores the first word in each line except for the very first line.

I'm having difficulty with some strings of varying 'meaningful' length from a different database (not under my control) that I am trying to trim in my vb.net code.
I only want to remove TRAILING whitespace... therefore, I can't really use .trim method.
The reasoning behind this being that the field sent from the french database usefully uses a <space> to represent a 0 (as you do).
The string is always the same length but the meaningful length can vary, an example being 95WO<space>5CA<space><space><space>...etc
Or it could be this...
<space><space>WO<space><space><space>... etc
Or this...
<space>5WO95CA<space><space><space>...etc
I've got my methods in place to split the string into pairs and perform various lookups but until I can remove the trailing whitespace I'm a bit stuck

Here is what I got so far:
1) I have a VB2010 Project. The form contains the following things:
1 RichTextBox (RichTextBox1) 8 Buttons (Colors: Red, Green, Yellow, Blue, Teal, Pink, White, Black) (Button1 until Button8)
1 Button "Copy Selected Text" (Button9) 1 TextBox (TextBox1) 1 Button "Copy Finished Text to Clipboard" (Button10)
2) Here is how the program should work:
I write some text into the RichTextBox I select specific parts of the text, click one of the 8 color buttons and the selected text becomes that color. I do that until all the text is randomly colored e.g: Red Green Yellow Blue Teal Pink White Black
I select all of the text "RedGreenYellowBlueTealPinkWhiteBlack" I press the "Copy Selected Text" Button (Button9) The selected text should become visible in the TextBox like this: ^1Red^2Green^3Yellow^4Blue^5Teal^6Pink^7White^8Black
I press the "Copy Finished Text to Clipboard" (Button10) The character count (length) of the TextBox1 should not exceed 32 characters. If it does show message box. The whole TextBox1 should be copied. If the text is successfully copied, show MessageBox with "Success" else show MessageBox with "Error".

I Would like to position the cursor in a text box using X,Y coordinates with X being the line number and Y being the column number. Is there any way to determine the line and column numbers of a textbox that is full of text. Using the .selectionstart paramenter only lets you position the cursor a certain distance from the beginning of text but there is no line information that I know of. By the way, I not an expert at VB so bear with me if these questions seem kind of basic.
