I cannot figure out how to incorporate the number of days into the input box then get it to loop and count the number of times the User inputs in the number of days. Then I have to incorporate it into the equation to get the total distance D = MPH * Hours. What I have right now wil not count up the number of days and locks up after I input one number and will not add anything to the listbox. Because I also have to make sure that they cant add nonnumaric values and the number of hours per day cannot exceed 20. I have put things in and taken them out but it has been 2 days and I am lost now

Associate Multiple User Input Fields Using A For / Next Loop?
Mar 20, 2012VB.NET 2008 windows app form.I have a groupbox with several checkboxes, comboboxes, and textboxes within it.With the help of StackOverFlow members, I've learned how to use the FOR/NEXT loop to find all checkboxes that are checked.[code]As you can see by the code sb.tostring will print every checked checkbox name on its own line.How do I associate the proper combobox.selecteditem, textbox.value, and checkbox name to print out on the same line.When I say proper...example; checkbox=pen, combobox=color, textbox=quantity.Let's say my other checkboxes are different items and the rest of the boxes are the same.
View 2 RepliesValidate User Input - Loop Conditional Statements To Indicate Errors?
Mar 20, 2011I have several text boxes I need to validate. I am not understanding how to validate in Visual Basic 2008. So I deployed standard If Statements to handle bad data. I am having two problems.
Lets say the user entered wrong data, example, numbers; an error message is displayed. The text boxes cannot contain numbers, be left empty or contained characters, like !@#$. The problem is if the user enter text, and then entered a wrong data again the code does not work or display error message. How can I make the conditions so that they throw out error message even if the user had previously entered good data.
Another example: If the user enter good data in text box 1 and bad data in text box 2, the error message does not work.
Finally, how do I filter out characters to allow only text. Is there a way to use this code on multiple text boxes with out writing the entire code for each form control?
Here are the conditional statements.
Private Sub btnDataSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDataSubmit.Click
If IsNumeric(txtDataEntry.Text) Then
lblErrorDisplay.Text = "Invalid Name!"
lblErrorDisplay.BackColor = Color.Red

View 5 RepliesVS 2010 : Use A Stop Button To Stop A Loop?
Dec 7, 2009I created a form and have the variable inputs for 4 motor run statements. Then with a start button the script starts and it is surrounded by a for next statement to loop 10 times. It works fine but if i need to stop the execution of the script with a stop button. I put the stop in a new section but of course does not work to do a motor stop. It just causes the exe to not respond till the loop is complete. Just need to be able to stop the Run1_Click button section.
Edit:I do not mind if it finishes the 4 motor run commands and then stops execution of the loop. So need to figure out a way to trigger a stop from a button on the form to stop the cycle. For the future the loop will be a variable integer input so 10 will not be the standard.
Edit::Does a ' Do ' statement sound like the thing to use? If so how and where would I place that? Have a Stop button on the form and it would stop after the 4th motor run command.

Dec 28, 2009ive been steaming on this one for quite some time. Ive got a program that relies on remote control of the computer, and i need to be able to take a webcam image without the user having to press buttons etc. So far, ive gotten to the point where i can find my webcam, and with the help of a button, start a preview, then take the picture and save it as a jpeg.Problem is, when you press the button to start the preview, another dialog box shows up (not related to my code) prompting me to select a video source..Im confused kus it seems as though the list i find on form_load does nothing at all if when i press the button it prompts me with the same list.Well you can infer from this that i cannot use the btnstart_click(sender, e) on form_load because it opens a dialog that wont close until i press ok, and i already tried to sendkeys enter, it didnt work.anyone have any idea how i can either alter my code, or make new code to take a web cam image, and save it with no user input?

VS 2008 - CipherText Encryption (User Input)
Jun 15, 2010I'm a complete beginner to programming alone, let alone VB.net. What I need to do is encrypt a block of text inputted by a user using a keyword that will also be inputted by the user. This is all to be done using ciphertext, so naturally the user would be informed the keyword can not have any repeating characters. I figure the English alphabet will be predefined in capitals and lowercase, then the keyword will be read character by character, removing those characters from the alphabet array and then appending them to the end of it (to create the new encrypted alphabet). How to read the keyword character by character, and then removing the corresponding letter from the alphabet. The best I can think is to check each character of the keyword against each character of the array which I'm sure is much more work than I need to do.

VS 2010 Stop A Block Of Code Executing When User Clicks "Stop"?
Mar 1, 2011I have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

VS 2008 - Generating Custom Code For Windows Form From User Input
Mar 30, 2009How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code:
function Init(Quest)
Then from here a user would input a quest name, type and zone in a interface using windows forms.
Ex:
Code:
RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm")
end
This part a user would enter in his interface what would an NPC say if accepted.
[Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like:
AddQuestRewardFaction --- (Quest, Faction ID, Amount)
AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat)
AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s))
Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.

Like, when I click the save button, the program will prompt the user for an integer value, and I would like to validate if the user has inputted a valid value. If the user fails to input a valid value, then the program will re-prompt the same message again until the user inputs a valid value. Eg:
If MsgBox("Add copies to this book?", MsgBoxStyle.YesNo, "Adding Book Copies") = MsgBoxResult.Yes Then
Dim CopyQty As String = InputBox("Amount of copies to generate:", "Add Book Copy")
