I have 3 columns in a unbound datagridview, "length" "height" and "Total". Total = length x width and the final total in TextBox outside of the Grid. I found question simalar in this forum and tried the code but i am getting errors.The following is the code i am using
I have a program that allows a user to input numbers from an inputbox and it displays the Total numbers entered, the sum of the numbers entered, and the average of the numbers entered. What I can not seem to find it how to have it display the largest number entered. The code I have so far is,
in the keydown event of a textbox (textbox1) as text is typed in i want it to "knock off" items that dose not include the text in either colum 1 or colum 3.How can i do this ?
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles richTextBox1.TextChanged 'code goes here End Sub
I want add a Total textbox to every form.The total will add the values that will be entered in the montant textbox. So the total will take the specific value of that texbox for all the entries that the user will have and add them. How I can do so?
I have a text box in form1 that displays the total, I want to carry this over to form 2 into another text box as I navigate between them, how would I do this? Also I have a button on form2 to return to form1 but I need all the data that has been input by the end user to be cleared from both forms when returning, again how would this be completed?
I am creating a Map Rotation Randomizer for my Call of Duty clan, and I am having an issue with understanding how to randomize the text from the list and placing it into another textbox.
Here's what it looks like right now: All textboxes are multi-line.
When I click a button for a game (CoD4, MW2, WaW), it places the map list into the left textbox like: mp_bloc mp_broadcast mp_crossfire etc.
When I click the button with ">>>", I want it to randomize that list and place it into the right textbox like: map mp_bloc map mp_broadcast map mp_crossfire
Or if I click it again: map mp_crossfire map mp_bloc map mp_broadcast And so on. I think I need to create an array, but I've never worked with those before as I'm still new to learning programming. I'm not even sure what controls I need to put on the form for that, if it even requires any.
I'm creating a new (or more) tab(s) with a multi-line textbox (filled) at runtime and some text is added. Each time I change/select a (new) tab it needs to search for a string and if found...blablabla.How do I get the control to search in?
I have a DataGridView1 where I have 6 columns and 0 rows (they are added additionaly in the application) and also have a TextBox1. How can I calculate all data from the second column to the TextBox1? For example, I'll run the application and add rows, where the text in the second column will be: (4, 8, 9, 1)... it means 4 rows...
So how can I make the value of those numbers (22) show in the TextBox1, so that it will calculate the numbers and show the sum in the TextBox1?
So I still working on a program that shows this. This is the code that I use two show the SA and PLATINUM text because on the file they are not the only characters on the line, like this:
set username=sa set password=platinum code to search only those two words.
How do I add, for example, all the numbers in the textbox (they are separated by spaces)? I tried a couple of methods but no luck so far. So for example, this is what the user will input in the textbox:
i need some help i want to add the total of the numbers inside a particular Listbox and the total should be in in Label form Like (Label1.text = "Total").
this up but this line below seem to be the problem this sentence (Textbox1.Checked) its supposed to add all the numbers up and give total in a input box under the score line is the complete code sorry for wrecking anyones head cause mine is demented
from mark Protected Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles yourtotal.TextChanged
I can print the current page number with the use of a static variable. How do I find out the total number of pages? Is there any particular variable in which this number is saved and can be replaced automatically later on just before printing commences by some internal procedure?
[code] I am trying to place random numbers into labels, but the process that i am doing is taking way to long, just wondering if there is an easy way around this? I also need to know the answer to the sums that get placed into the labels and then check that against the answer in the text box.I have looked all over the DIC forums and nothing meets my queries.Please help, this is just a quick program for my son so that he can get some sums into him.
For this code, its saying that "File not declared". My textbook isn't specific at times. I was wondering how do I declare "File" or what else will I need to declare.[code]
I have a series of text boxes with numbers. They are an array called txtBF(0 to 16). I am trying to take the value that is to be displayed in the text box and make it have only one decimal place. I have tried using this code below but I keep getting an error message Run Time Error 13: Type Mismatch.
txtBF(11).text = Round(txtBF(11).text, 1) and I have also tried this txtBF(11).text = Math.Round(txtBF(11).text, 1)
I need some help with to make a messages system. I build a form with display a message code and the message.
Example : 0000001 : Not connected to network
The problem is that i want to store in a central place where the numbers and the message will be stored in the code. I was thinking about a array to store the date.
i have one more issues, and hope is the last for now. How can I limit a textboxe's input to only numerical with certain range of values (eg -10 to 10) and with that happening while I type in the values?
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.
How do I code the total cost to give me a pound sign with the total cost at the moment when the total comes up for an example it gives me 3.6 when I need it to show £3.60 here is the code I have so far. [code]
I have a DataGridView1 on my form that shows results after filtering from various events and has Quantity as one of it's column. Now i want to show the sum of displayed Quantilty cell in TextBox1 everytime the DGV is filtered.
I'm brand new to Visual basic (yesterday) and I know this is likely to be a very basic thing I am asking about which only adds to the frustration i've been feeling the past half hour or so of searching online lol, so bear with me.[code]...
