[2005] Setting ForColor On Text From A Disabled Textbox + Removing The Right Bar

Jan 7, 2009

As some of you are aware of, I am fairly new to VB.NET. I am trying to learn as much as I can. I have a textbox which is set to multiline. It's setup to accept a maximum of 500 characters (10 lines of 50). First of all, since it's size is fixed, how can I remove the right bar on the left as im not using it (the scrolling bar).

#2, once a user click on a button, I disable the textbox and display the text. I can set the background color, however it looks like when the textbox is disabled, text is gray and can't be changed. A fix I found is to use a label and hide the textbox, but are there any easier way ?

Textbox - Text Box To Only Accept Numbers?

Apr 2, 2012

I'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems.

Removing Numbers From File Name?

Jan 23, 2012

Lets say I have 500 pictures, they are named by date and lot code as well as what they are.

Here is an example:
20110406_174805_T0A_V1113465_F.tif

This configuration is not able to be reconfigured so I am not able to use a left or right string to get my information. What I would like to do is remove all of the numbers from it and then up until the first letter (if possible). Then I could extract the next 3 characters to get what I need. I then need this put into a variable for comparison to another string.

Ensure Textbox All Fields Populated With Text And / Or Numbers

Apr 17, 2010

I have a form (formA) which contains a tabcontrol with two tab pages. Each tabpage has 6 textboxes and 3 comboboxes. In addition to the tabcontrol there is a separate combobox and textbox. The question I have, is how to best ensure that all these fields are populated with text and or numbers? From this a start button is pressed which generates another form (formB) which requires the fields from (formA). If for instance 1 or more fields is not populated, then generate a message to show the user which 'box' requires data. Only when all fields are populated will this enable the 'start' button.

Removing Duplicate Numbers In Listbox?

Jun 10, 2011

I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.

Here is an example of what I am doing:

LISTBOX VALUES
2
2
3

[code]....

When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like

LISTBOX VALUES
3
7

Inputting Numbers Into A Textbox And Formating The Numbers?

Jul 30, 2009

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.

Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

Box - Conversion Error - User Enters 6 Numbers In 6 Different Text Boxes - Displays The Larger Of Those 6 Numbers

Oct 4, 2011

I am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.

Here is my code Example

CODE:

This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.

CODE:

Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.

CODE:

And do this with variable number 2, 3, 4, 5.

I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.

Removing Specific Lines Of A Multiline Textbox

Feb 26, 2010

What I am trying to do is remove lines of a multiline TextBox based on certain criteria, such as the number of characters or words. For example, if I paste a list of phrases into the TextBox, I want to remove all phrases that contain more than 25 characters. Once the phrases are removed, I then want to remove the empty lines that are left behind, but I have commented out the ".Replace(vbCrLf & vbCrLf, vbCrLf)" for the sake of making the results easier to follow (see screenshot from Excel below, which includes a blank cell wherever a phrase has been removed).

Here is my

Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
Dim lines() As String = TextBox1.Text.Split(vbCrLf)

[Code]....

Why is it not "blanking" the entire line in ALL cases where the line contains more than 25 characters?

How can I do that? Does it need pasting into a rich textbox first before processing?

Removing The Zero From Text Box?

Jul 22, 2011

I can't get a zero into a text-box, what I'd like to achieve is this: if the textbox is zero, then I want it to remain as a blank, until I enter value to that field.Actually When I activate the field via some other control, then I Never wants to display "0" zero in Textbox Fields, before operation done. By default which comes from the multiplication operation (txtUnitsPrice.Text = d1 * d2) into the textbox field. I have three Text box fields, i.e. Unit_Price, Unit_on_Order, Units_Price.

Unit_Price=0 or some time it have default value, i.e. 25, which display ok, but not the below field.
