I would like to validate some data from the user and their corresponding value.
e.g.
2 = ABC
6 = MNO
6 = MNO
7 = PQRS
8 = TUV
8 = TUV
3 = DEF
if the user had input the numeric data on textbox1, then the alpha phrase will show on textbox2.
What i want to run is that if i press the "execute" button, it will look for a word than can be create using these letters ( e.g COMPUTE )
Then it will display the word "COMPUTE" on textbox3.
Is there a function or method i could use to do that?

I am trying to create a new class to validate user input and then call that class from my main form. I am not looking for anything to do the work for me, as this is the last part of my project but I am looking for a place to start. I tried the isNumeric IF statement but I have to create an object to reference the specific text box. Can I be generic and say that aTextBox requires validation and then call that class?

View 3 RepliesI have a User control having two panels. one at the top border and second at the bottom border of the control.
The panels contain some buttons on the click of which i want to display some forms. But I want thoes forms to act like children of the user control i.e. like MDi Parent - Child (here parent being User control and child being the new forms which would be opening). Unfortunately i've not been able to find any way of do'in so.
I only managed make the form always on top. But what I want is when the form is on top, user cannot access the other application in the windows.
For example : Some messagebox won't let users access the other application until the users hit the OK button.

View 3 RepliesI am trying to figure out how to generate code from user input. In Visual Studio 2008, Visual Basic.My script always begins with:function Init (Quest)Then from here a user would input a quest name, type and zone in a interface using windows forms.[code]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.Is there anyone that can explain how I would go about doing this. Or maybe some kind of visual studio plugin that will help me out.
View 2 RepliesHow 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.
I 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
[Code] .....
I am new to Win Forms, I have a scenario here..When User enter ID in a textbox, I want to check that value in database and get the name for that ID before submitting the Submit Button.
View 1 RepliesThe following zipped up Visual Studio Solution on Skydrive is immediately buildable and runnable; a usercontrol on a Form. Problem? If you click on any of the Edit Buttons and move the Horizontal Scroll, the values as they change in the Label_Values are off by one when you release the slider button. I think this is a timing problem between the Paint handler and the Horizontal Scroll event handler at the very bottom of the User Control code. Sorry I didn't eliminate

Ive only recently starting fiddling with Visual Basic Express and Sql Databases. Ive managed to get a database up and running, and can query information from it. I have even created a form that can add a new entry to the table im using.The first form has a ComboBox that list the PlayerNames in my table. Form2 allows you to add a new name to the table, but anything I add isnt immediately updated in Form1. I have to relaunch the program to see the new entries. Even then, these new entries dont seem to be permanent as they eventually dissappear.The code I have for Form1:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
