View 1 RepliesI'm using Visual Basic Express 2010. I have the prompt, the textbox and the calculate button. For the answer do I have to make a separate label for the answer in seconds and the actual response "That will take (separate label for answer) seconds" I made a click event button and assigned the following as global variables at the start of the form:
Const intSpeed As Integer = 1207
Const intTime As Integer = 3600
Then I made a click event for the button. I don't know what the formula is. Basically the user inputs a distance in the box, the calculate button tells you how long it will take for the vehicle to travel that distance in seconds.
Here's the interface: [URL]
Criteria:
Are We There Yet?
The Thrust SSC, a super fast vehicle tracked at 1207 Km per hour (750 mph) was clocked on the Black Rock desert back in 1977. Build an application that will tell people how many seconds it would take to get to their destination if they were driving the vehicle. Of course this doesn't include having to stop for stop signs, travel through school zones, or slow down for corners.
You need to include the following:
1.) Design the application with a prompt label and textbox to collect the distance from the user.
2.) A calculate time button
3.) The form must have the text property changed to read "Are we there yet?"
4.) The objects must have both the Text property and Name property changed to an appropriate value.
5.) A constant global variable should be used to represent speed of the vehicle.
6.) A constant global variable should be used for seconds (there are 3600 seconds in an hour)
8.) A local Dim variable declaration can be used within the button click to hold the distance value.
7.) Variables should be declared with the most appropriate data types.
8.) Include a "Text Changed" event to reset the time in seconds to a blank value when the user starts entering in a new distance.
9.) Comment code should be included
I want my calculate button to automatically click 4-5 times upon the user clicking it once because it seems that it only works properly if it is clicked multiple times...
View 10 RepliesI've done this multiple times in VB and VB.net, but this one button is giving me terrible issues in just clicking it.
Here is the page source:
<button id="formSaveLnk" onfocus="this.blur()" type="submit" onclick="return false;" class="aBtn-btn"><span class="aBtn-b1"><span class="aBtn-b2"><span class="aBtn-bTxt">Leave�Feedback</span></span></span></button></span><span id="formSaveNoScript"><input type="submit" value="Leave Feedback" class="aBtn-sB"></span></span></td><td style="padding-left:15px" id="learnMoreId" nowrap="nowrap" valign="middle">
Here is the code snippet that performs this task. It's finds the button, but clicking doesn't work:
htmlDoc = .Document
htmlColl = htmlDoc.getElementsByTagName("Input")
For Each htmlInput In htmlColl
If htmlInput.type = "submit" Then
[code]....
This works nearly every time, but not this time.I've also tried searching for the TagName "Button" and clicking that based on the innertext value of Leave Feedback, but that doesn't work either. I've also tried playing with onclick with something like this:
For Each htmlInput In htmlColl
If htmlInput.type = "submit" Then
If htmlInput.innerText = "Leave Feedback" Then
[code]....
But that doesn't work either.
The pay rates for the project are:
a. Level 1 - $10.00
b. Level 2 - $12.00
c. Level 3 - $14.00
d. Level 4 - $16.00
e. Benefit Deduction Rate - 0.10
f. Overtime Factor - 1.5
For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.
When the Calculate button is clicked:
a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.
1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.
2. If the user chooses to continue processing, the focus must be set to the Hours text box.
3. If the user chooses to quit, the program must close immediately.
b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.
1. The pay rate is determined by which Job Grade radio button is checked.
2. For hours less than or equal to 40, the total pay is the hours times the pay rate.
3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.
4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.
5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal
places.
6. The focus must be set to the Hours text box.

View 4 RepliesI have a button and a text box. The text box should start out with number 41. Each time I click the button the text box number should decrease by 1 until it hits 20 then when the button is clicked nothing happens. I have tried multiple pieces of code from For counter 41 To 20 Step -1 to If counter <> 0 Then textbox -= 1, but it only works for one click. Not sure how to keep it decrease on every button click until i get to 0.

I have developed a small application. It has a MDIParent form on which the other childforms are displayed. I have a Panel on the MDIParent on which there are buttons to call up the MDIChild forms. Now my issue is, when anyone of the buttons on the MDIParents form Panel are clicked, it should check if another Childform is display, if it is then it (the active childform is closed) and the new form will be displayed. This part is working fine from the code below. However, when there are no active MDIChild form on the MDIParent form and if the button is clicked, the 'Else' part of my code below is executed. This generates the error as 'Object reference not set to an instance of an object'. So what is wrong with my code below?

'MessageBox.Show("hahahaha")

Instead when I click the button, it just paused for 5 second and displayed world.System.Threading.Thread.Sleep(5000) The code is just a dummy for a loop that I have.
