VS 2005 Read User Input Using Textbox But It Only Can Read Character And Numbers?
Jan 2, 2010
I know how to read user input using textbox but it only can read character and numbers. Is it possible that I want to read user input equation?
Example:
User type A+B
User put range of A and B.
1.25<A< 3.56
2.45<B< 9.87
I failed to read the equation using textbox. Is it there are other ways that can use to read equation input A+B?I am using VS2005 and VB.Net. I really new in this programming using VB.Net.

My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.

I am trying to make a program using Visual Basic that will allow the user to add links to web pages (such as www.google.ca) to a list in the program and make it so that they do not dissapear once the program is closed.
So to get into more detail, I have a text box, a listview, and a button. When the user types a link into the text box it needs to be put into an array (called "addlink") and then when the user presses the button, the link is typed into the listview as an object.
Then if the user clicks on that object in the listview, it will open up the browser using the WebBrowser command. How do I set the text in the textbox to an array once the button is clicked?
Specifications:
OS: Windows 7 Ultimate Edition
Software: Microsoft Visual Basic 2010 Express
Experience with Visual Basic: Average

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I am running Visual Basic Express 2005. I am trying to develop a program to send morse code out the serial port. I have created working code that can determine which character needs to be sent and toggles the RTS line on com 1 with the proper pulses. What I can't seem to figure out is how to be able to type in characters at a higher speed than they will be sent out the port, so as to be able to use the backspace key etc.

I have an assignment that is supposed to accept user input of random numbers. The only part I'm struggling with is I'm supposed to make copies of the array after the user is done inputting the numbers. These copies has to be sized exactly to how many numbers the user input. Am I supposed to use a counting variable and if so how?

I have recordsets in my MySQL database like this (in german): Karrieren im Porträt: Interview mit Thorsten Franck - „Ich liebe Produkte" Now when I get the data with the MySQL connector reader and write it into an xml file I get just this: Karrieren im Porträt: Interview mit Thorsten Franck Ich liebe Produkte As you (hopefully) can see, the minus (it's one of those long ones) and the upper and lower quote signs are not shown. The table is defined as UTF-8, the output of the xml file also.

Is there a way to make a DataGridView's column a combo ONLY in the "new row", and a read only textbox in all other rows? I want the user to be able to make a selection from the combo box, and when the row is finished and the "new row" moves down one, I want the column to become a textbox containing the what the user selected. My grid will be bound to a table witch contains a "category" column, that is drawn from a seccond table that i want the combo box bound to.

using for...next loop the program is supposed to accept 2 user inputed integers and display all even numbers between the two in one label and all odd numbers between in another label.
Private Sub displayButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles displayButton.Click
' displays the odd and even numbers between two integers
Dim intNum1 As Integer
[code]....
I'm not exactly sure what this code is doing. When I put 1 in the first number and 10 in the second number, the odd label only shows 9 and the even label only shows 10. Another example is when I put 2 and 15, the odd label comes out as 15 and the even label is 14. I'm very new to VB and programming in general and have just started getting into for...next loops and don't fully understand what the counter is or how the loop is supposed to work. I guess I'm having 2 problems. One is that I don't know how to make the program find the right numbers(my logic is off? or how I set up the loop isn't right?) and the other is the labels are showing only 1 number each instead of all the numbers in between on their own line.

I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.
