I am trying to unit test for data being input into a textbox (txtPrice). If it is not numeric, it throws a messagebox stating that the input must be numeric. However, when I unit test, I can't figure out why my test fires the message box twice.THis is my (simple) unit test:
Public Sub txtBoxes_LeaveTest()
Dim target As frmEstimate_Accessor = New frmEstimate_Accessor ' TODO: Initialize to an appropriate value
Dim sender As Object = Nothing ' TODO: Initialize to an appropriate value[code].....
My understanding is that for unit testing, you declare the sender, and (in this case) set the sender to some value that will trip the message box. 112L should do this on the leave event. I then write my expected, which in this case is 112L, fire the event, and then get the actual out of the text box. I then Assert.AreEqual to ensure the expected and actual are the same.
A form has many buttons. One of those buttons contains code to update the TableAdapterManager. One of the many TextBox controls has code in a Validating event handler. There is code to make sure a US phone number is formatted properly.If the user tabs out of the TextBox the Validating code works perfectly and show a message to the user if the phone number is not properly formatted and the focus is place in the offending TextBox.If the user clicks on a button that has code to update the TableAdapterManager the Validating code fires but instead of focus remaining on the offending TextBox, the code in the button Click handler also fires.
I would like to stop the button code from firing.Here is the code for the Validating event of the TextBox:
Private Sub TextBoxPrimaryPhone_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBoxPrimaryPhone.Validating ' Make sure the phone is formatted correctly.
[code]....
What additional coding to I need to include so focus remains on the TextBox?
[code]...Basically, I'm trying to make it so when you type a number between 1 and 16, it runs it through the equation and displays a result in a label. This event happens after you press a "yes" button.The problem is when I test the program I put any number from 1 to 16 and I get my own error message, specifically the <1 error. It doesn't make since because I type in numbers that are greater than 1...
I have two separate web services, the first configured to extract data from a live database, the second from a test database.
When consuming these web services from an application the object returned is a MyMessageData class which is defined in the web service.
In the application I would like to instantiate a empty the MyMessageData (from the live web service) and then use a configuration setting to decide which web service to retrieve the actually data from.
This does not work for test because the application does not see the instantiated MyMessageData class from live as the same type as the MyMessageData that is returned from the test webservice. [code]....
I have an application, for sending SMS to mobile phones, using a GSM modem and AT commands. It works perfectly, except in one point. If the modem have some problem, for example doesn't have network, or even doesn't have a SIM card, I dont know if the message was sent or not. How can I test if the message was sucefully sent?
In the above code when i click the button on the form, it doesnt display the message in test(). I have to click two times to display this message. Why this happense and what can i do to fix this? both the classes are inteh same project scopecheers.
EDIT: Solved (see comments) I have a For loop inside a sub, and right below it I have a MessageBox function. Everything compiles correctly, however for some reason, if the loop executes and exits successfully, anything outside and below the For doesn't get executed.
[Code]...
it displays only 10 items in the ListBox afterwards. I've searched everywhere, but I did not find anything related to such an issue. I'm kinda puzzled, anyone got a clue of what's going on? EDIT: Forgot to specify, the sub is actually a TextBox.TextChanged event
So my teacher gave us this assignment that I'm having trouble understanding why she wants us to write outside of the button Private Sub.1. Write the code for the Calculate Total and Grand Total button a. Declare a variable to accumulate the individual totals outside the sub procedures b. Calculate the total by multiplying the selected number of atendees by the selected cost, and display this total in the label next to Total c. Calculate the grand total by adding the total calculated in step 3.b to the grand total variable. Display the grand total next to Grand Total I'm don't understand why she says 1a. I feel like you can just write all the variables in the same Sub on the calculate button.
Have to develop an application that will let me choose between cell phone plans, individual and family plans i have the forms and all choices done,. new forms open and old ones hide to keep it clean. i think i got all the variables declared, and got no debugging errors, but when i select the options, it always gives me the following:
1. adds one more phone than selected
2. only shows phone subtotal, tax and total
3. prices for options and monthly fees never show
Here is my code for all 3 forms
Public Class frmMain Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click End End Sub
I am developing an ASPX VB.NET file. My assignment is to convert an integer representing week of the year into that end date. For example, if user selects Week 4 for 2011, I want to get date = 1/22/11. How do I do this in VB.NET?
I'm supposed to change the keyboard language to Farsi(Persian) by using API functions while the program is running( It's a plain form with a text box). I'm already late for the due date.
I have two drop down boxes in my program. When you select an item from the first drop down, it populates select-able items in the second. When I select something in the second and then change the selection in the first one, the values remain in the second. How do I "reset" the second drop down when the first is changed?
displaying the first 10 Fibonacci numbers. My code displays the following result: 1, 2, 3, 5, 8, 13, 21, 34, 55 and I need it to also display the first two Febonacci numbers (0 and 1). How would I do that?
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim a As Integer = 0
If i have a class called A and a class called B, if B inherits A that means A is the super class and B is the subclass. I have been asked to describe why class A is not an abstract class but as i see it class A is an abstract class A, as it has been created for Class B to use in the future, is it something to do with Class B not being able to access the fields in Class A as although they are private by default?
Working through trace tables and wanted to check to see if my results where correct, I have designed the following code to check each stage of the loop, but the code keeps throwing up an error about casting when i try to run it. I can see when the error comes back that the writeline is holding info but what have i done wrong.
For a school project we need to visualise a computer network graph. The number of computers with specific properties are read from an XML file, and then a graph should be created. Ad random computers are added and removed.Is there any open source project or algorithm that could help us visualising this in VB.net? Or would you suggest us to switch to java.
Update: We eventually switched java and used the Jung libraries because this was easier for us to understand and implement.
I've been taking a class on it this semester and am starting to get very confused and behind. I've been pretty stuck on my hwk assignment for this week and was wondering if anyone could possibly hint at what I'm doing wrong or if I'm just completely way off. The whole rows and columns in arrays seems to be throwing me off now. Also, sorry if this is not the right place to post something like this I was not sure which section this fit under.
I was given an assignment to "write a program to print only even numbers between 6 and 16 using events", but I don't even know where to begin. The main thing I am having difficulty with understanding in this assignment is how I am supposed to specify that it only print even numbers in the given range of numbers.
Am I going to have to do a Mod2 code for each individual number and have it exclude any with the result of 1? Or is there another piece of code specifically designed for such an occassion? Perhaps there is some type of equation I can have the program read in terms of a variable, which holds the values of 6, 8, 10, 12, 14, and 16? I am just genuinely confused on how this is supposed to be programmed.
I have 202 .html files and at the beginning of each file, I need to add a chunk of php code. I could make this myself, but to be honest, it would take me forever and I might as well just manually edit them lol. All the .html files are in one folder.[code] one other thing that would be VERY cool, is if it could add the files that are not edited to a listbox or an outputted text file.
I am learning inheritance in VB.Net. A homework assignment asks me to write a base class with a name (String) property and a ToString method that displays the name. It also asks me to create some child classes of the base class and also implement a ToString method in those child classes. Is it possible for me to call the ToString method from both the child and base class?
[Code]...
Again, I am wondering if there is a way to call the ToString() method within the child class and then base class to generate output something like: "Hello VB.Net This is the name"
and from VB6 project I reference to Test.dll but an error messege was appear A reference to Test.dll file could not be added (If I create VB NET project and reference to file Test.dll it OK )
I am using a combo box on a form in vb net 2008. I would like the user to be able to either tab to the control and then select an
item OR the user could click on the combo box and then select the item.
unfortunately it fires twice when the user clicks on the control. This is before any items are selected. I have tried placing it in mouse down , focus , key down etc etc.
It does not fire twice for the enter event so I tried to use that alone, but then there is no dropping down of the combo box when the user clicks on the control. Is there a way to release the combo box enter event on the mouse click event?
I am trying to wait for the webbrowsers page to have finished loading to then carry out the next part of my code.However i am having problems because the DocumentCompleted event fires twice?
I am trying to create a winform that will allow me to close when the form either loses focus or deavtivate. When I do Me.Show, it will call the deactivate? Is that right or is weird? The way took it was it fires when it either looses focus or is no longer the active form.
Also it seem like I have to click the form in order for it to work right. I tried Me.focus and that does work the way I expected.
I read data into a DS from an XML file. The user has the ability to "Save" or "Save As" at any time. They can also "Open" an existing file or create a "New" one. (brilliant, don't you think?)
I need to make sure I ask the user if they want to save their existing data (i.e. rewrite the XML file) if the DS has changed from the XML load or from the last time they Saved. On Open, New or exit I have been checking the HasChanges function on the DS. This doesn't work the way that I need. I use AcceptChanges throughout the program to commit values to the DS. This appears to kill the HasChanges even though the DS is now different than the XML file.
Is there an event in the DS that fires when data changes? If so, I believe I can set a flag that can be checked later. If not, is there any other way to track that a DS has changed after the initial XML load? Would reloading the XML into a cloned DS and comparing the two work? Seems like a waste of "time", especially with large XML files, but if it's the only way.
I have a class with two descendent classes (child, grandchild):[code]When a property changes in the Measurement class I raise a OnCrucibleOxidizedMassChanged event:[code]However, the OnChanged sub gets called twice, even though I only assign a value to CrucibleOxidizedMass once.
I have a problem with a ComboBox to select FontStyle. I need to select the font style twice to fire the event in SelectedIndexChanged Event, that means for example to click "Arial Black" twice to set the text to this font.
Im parsing through a xml file and a error is thrown and the event is fired off but the exception is still nothing even though it tells me theres an exception.[code]Thats how the code is set up. It is enclosed inside a try statement to catch the error but when the event is raised "ex" is nothing.[code]
