View 3 RepliesIs there a numeric text box, not an up-down box, a SIMPLE numeric box into which the user can place a number, 5 boxes actually, then on command have the five boxes added and the sum displayed?
View 8 RepliesI'm writing a program, intended to get a number of points from a label control, and decrement the number in the label control as the number in the Numeric UpDown is increased, and increment the number in the label control as the number in the Numeric UpDown is decreased.
Here is an example of the type of code I'm trying to use to do this with:
Sub UDStrValueChanged(sender As Object, e As EventArgs)
Dim points As Integer
Dim tempcheck as Integer
Dim oldvalue as Integer
If oldvalue < UDStr.Value Then

Im trying to code a program, that will only accept numeric values in a text box, and if you try to enter non-numeric values you get a message box that says "Please Enter Numeric Values Only." Is this possible?

View 6 RepliesI have an application where the user and search the database and return the values from it. They can also figure the Average, Median, and the Standard Deviation from it. BUt I have a problem with this since the business rules won't allow the result column to be anything but a string so now I am getting error messages on the Select commnad text since it is trying to perform the calculations. I am wondering if there is a way to convert the values in the command text to a numeric value then perform the calculation. Here is the code I am using at the moment.

I currently have a subroutine that generates a file with specific parameters, and it relies on user input in 2 fields. Now I also have a numericupdown control. What I'm looking for is a way that if Numericupdown.Value = 3 then it will generate 6 textboxes and once the parameters are filled out completely it will generate subroutine times(numericupdown.value) and output it to a single file.

View 4 RepliesI only want to place the numerical data in an array. At the moment I have the following code to do this. [Code]. This code places the numbers in the data array when there is not any text in the file, i.e. when there are no headers. I would like to place the headers in another array, and then have the numbers in the array as in the code above.
View 5 RepliesI'm working on a program for a side business I run with a friend, who is a non-programmer.I've done a program before, using IO.StreamReader and IO.StreamWriter to read and write lines to a text file.
But now, I'm working on reading text data (it's output from an old legacy program) that reads a first and last name, and the customer number (6 digits) from one file.
Then, it uses the data (customer number) read the first time to cross reference the zip code and status from a second file, and display it.
The Data in the Text Files are as follows:[code...]
How would I begin parsing for the first and last name, and the customer number to assign to different variables?In the line that references names.txt I meant to put customers.txt.
That's a snippet of code I took from a previous program, so I know how to read the data, just don't know how to extract it.

I find myself copying single files to multiple different machines, so would like to create something to help.I would like a numericupdown, which dynamically adds text boxes (which will be destination file paths). I will obviously need it to remove them too when I decrease the number.

I read a csv file into my .net program using ado.net and display it in a datagridview.In the file I have two rows. The first column is a component id, and it is supposed to be numeric. But the user can edit the csv file before having my program load it, and accidentally put text there. That is something I want to edit when he presses a button to add the data to the database. So let's say he puts a value of A in the first record and a value of 1 in the second record. Or vice versa. What is displayed in the dgv is a blank in the first record and a 1 in the second, or 1 in first and blank in second. If both csv records are A, then what is displayed in the dgv is an A in both the first and second records. I don't understand what is happening. The fact that there sometimes is a numeric in the column makes it think it is a numeric field and therefore only display numerics and blank otherwise, and the fact that there's always text in the column makes the code know it is a text field?
View 2 RepliesI have a textbox which has a numeric value that changes - would it be possible to check if that value matches two numeric values in a text file? and if the value matches then to display some text in a label? The textfile only has fields displayed like so
Horizontal 55
Vertical 16
So I would only need to check if the numeric field in textbox matches the two numbers in the second column. In the past I have use System.IO.File to create/delete/append to files but I havent come across anything like contains.
I am developing an app that will import numeric data and export it to various text files using ascii templates. I am basically converting the template file into a single string, replacing application fields in the string with {0}, {1}, etc... and adding the result into an array that is then passed to the String.Format(str_Template, Params()) to provide the final output. I have set it up so the template will use the standard VB.Net formatting syntax.
A simple template example:
{<prt_Mark>:G} {<prt_Qty>:F2} {<prt_Length>:F2} {<prt_Remarks>:G}

Dense student here with little sleep here during finals week...I have a text field being read on a button click event (along with lots of other information being read). This field needs to have a number entered.
I either:
1) Force a default value (i.e. - "2")
2) Verify there's something in the field AND that something is numeric...
I have encrypted a string to something like this:
1. Asak2$)kla1015QAXKFskfa332aSJ2(Ska@Skljcmcel3p.lq,aowpqaskla2@)Skx.:Pdm^),dfs;
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.
I will then confirm the (2) from the client.
So, I've got a text boxes which loads up a content from a XML file, usually a numbers I want a button, so when I will change the numbers on the text box, the data in file will change as well, in other words a save button That's how the data is being taken from a file

I am reading a data file and storing them in an array of string.Data is random, could be like "1","2","133,18" but sometimes there can be missing values like "?".Once I load the data in the array, I want to check if at least a majority (like 60% of them) are numeric values.If yes, then I wanna track down the higher and lowest value in the array, and output a range of 5.Loop through the array
If 60% of them are numbers (integers or decimals) then find highest value, find lowest value end if produce range
If for example lowest = 1 and highest = 100, range of 5 means 0,20,40,60,80,100 (so 5 ranges are 0-20, 20-40, 40-60, 60-80, 80-100).Also if the ranges turn to have decimals due to weird numbers, I would like to round them up.My problem is, in order to find highest and lowest when there are non numeric values in the array like "?", how should I handle those? I was thinking of something like Double.NaN but I would have to have an array of doubles.
I have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]
I cant seem to find any link or topic regarding my problem. I have 2 forms in a project, form one has labels and adjacent combobox while the other form (form 2)has textboxes with adjacent combobox. I am supposed to change the text property of the labels using textbox entry from form 2 and add/delete/change combobox contents in fom 1 using entries combobox at form 2.
View 13 Replieseveryone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.
My application appends incoming report data onto a RichTextbox control. As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish

View 1 RepliesI want to force all capitol letters in a label and when text is input into a text box. How can I do this?
View 1 RepliesI have this problem but I already simplify the code as below:Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Label1.Text = "hello"
System.Threading.Thread.Sleep(5000)
'MessageBox.Show("hahahaha")
Label1.Text = "world"

What I'm trying to achieve here is, after I click the button, the label1.text should change to hello, and after that to world. But I couldn't achieve that. Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.
I am currently working on a piece of code that allows the user to change the colour of some text in a text box. I have done the size and fonts fine but colour i am struggling on.
