Can't Change Textbox Backcolor
Jan 10, 2010I'm building an app that is a basic daytimer type of app. My problem is that I can't get the textbox(Textbox1) backcolor and text to change when I need it to. For instance, if there are events for January 12 and the user clicks on the Jan 12 link in the Calendar control, if there are any events in the SQL table for that day it should populate the appropriate times. The funny, or not so funny, thing is that I have another textbox named "TheEvent" that I can change the backcolor and text on with the code below and it works fine.[code]...

Readonly Textbox Default Backcolor
Nov 21, 2011VBbasic 2008: I have a readonly textbox in a panel. The background color needed to be change to white for a more "readable" text. The problem is when I set the panel "enabled= false", the only control that does not look "disabled" is my textbox because it stays "white"! Even if I set the textbox to disable, it stays "white". How do you change the default backcolor of a readonly textbox instead of "forcing" it to white? Is it possible?

Change Backcolor Of Textbox Based On The Value Inside It?
Dec 31, 2010Lets see if I can explain-I have a text box (rich text box) in a form. Inside the box, some data gets put in there- specifically insurance information.
Normally, the box doesn't need to change color to alert the user there's a problem with the text that's inside, because the information is usually good.But there are a few phrases that need to alert the user there's a problem.
For example, if the words "Not Found AS OF:" appear anywhere in the box, I need the background to show red.Or, if the words "Letter #1" appear in the box, it needs to show red. Absent of any key words, the box is normal (white).

Search And Read Textbox?
Nov 12, 2009I am working on a new application that retrieves webpage source info and displays data based on that data. Currently i have it read it from a textbox. What i want the application to do is read this textbox or textfile and seach for <name= and then read the rest of the line that its on. The source of the specific page i'm talking about will sorta look like:
<name=ASDF, Rank=2, Gender=0><blahblah234981723948> <name=A, Rank=3, Gender=1> <name=F, Rank=6, Gender=0>
and after each thing that contains <name= and all the way to the next > it saves the data to a string then adds to listbox
Since this might be confusing to you heres my pseudo
dim Users as integer 'counter
for each line in textbox1.text that .contains <name=
users=users=+1
listbox1.items.add(whatever is after name= and before , in source)
next
and then after that i want to retrieve the gender and rank and ext but you get the point..

Read A Decimal Value Via Maskedtextbox (or Textbox)?
Jan 22, 2011In COBOL, I read a value (a currency amount with 2 decimal places, for example) via a picture clause (and a screen section, of course), like:
WORKING-STORAGE SECTION.
01
VALUE-TO-READ PIC ZZZ,ZZ9.99.
...
[Code]....
The tricky part here is, whenever the decimal sign key is pressed, the input procedure understands that the following number is to be displayed to the right of the decimal point (not left).
Now, I'm trying to do this in VB. Unfortunately, my all attempts failed with MaskedTextBox.
Do I have to hardcode this procedure in my program, or is there an easier way to get around this?
