I am working on this microwave oven application and so far everything works well. I am wanting to add a pause button that pauses the timer. Is this possible? I've tried the code timer1.enabled = false but that doesn't work. Am I going about this wrong?
View 3 RepliesI am at college and am creating an app. however i have two main problems within my app. my app is a pizza app which will allow staff within a pizza shop to send the orders to the kitchen (this is just a listbox).but, the math doesnt work, the correct pricing isnt being displayed in the label for the orders for some reason. I have tried different ways of writing and placing my code but the result is always the same. also, i have five customers per table. if i select all the customers orders and click on send, only customer two's order will be sent. not any of the other customers, but if i just do customer one on its own, it works.

I have 3 forms 1 -mainform which loads when program is open, and where you select the datafile you want to use and input default information in about 20 textboxes 2 butons 1 to each page 2 -has 3 comboboxes and about 20 textboxes worth of information pulled from the database. then 20 textboxes the user can enter values to compare against the default values coming from form1. and 20 boxes that have calculation results 2 buttons one to each page 3 -same as form2
I created a textbox font format function in form 3
When I load program and click button for form3 everything works fine, i can then click button to take me to form2 and vice versa back and forth no problem
When I load program and click button to form2 I get a date casting error from the function on form 3
Why would I even get this if i havent shown form3 yet??
in Form1, I have this code
Dim FormTwo As New Form2
FormTwo.ShowDialog()
Close()[code].....
if I use Application.Exit, it will close all 3 forms.. But all I want to use is Close so that every time I show the Form2, it will close the Form1 first.. the same when I show the Form3, it will close the Form2 first.
I started to create the MathQuiz and it is working good as per the provide codes. I was also able to add 'Percentage Correct Answers' and some other details.I have added a new form with some buttons and that is working as well, just simple stuff and all good fun playing with it.
But here is my challenge:When 1 or more answers are incorrect the program is opening a new form (similar to the main form) and it shows the equations again. I did that with "Correcting.lblLADD.Text = addend1", etc. in then main form. In the form 'Correcting' = Form3.Designer.vb I have tried to get the Text into a Number but nothing works for me. Also Tried to make addend1 in Form1 Public but the value does not appear in Form3. Form3 has also a Private addend1 as Integer.Even if I give addend1 in Form3 a value Form3 does not calculate.Maybe it does but I can get it to work. I have tried to get a MessageBox to show up when the answer in Form3 is correct but the MessageBox does not work either.
IThere's a button on the toolstip that's always enabled for form2 so they are always able to search the database.When a user is on form1 and selects the link button. They are taken to form2 to select criteria to search. On Form3 they choose 1 item in the grid andcan select the Link It button on the form to link the 2 selected grid items (form1 and form3). Since form2 and form3 are available at anytime.my problem is knowing when the Link button on form1 has been chosen and after a successful link to not allow anymore links. Technically, they could pull form2 up via the toolstrip or an existing form2 window and Link as long as Form1 is on the screen but I do not want this. It's as though I need a global variable to set to True/False.

I am creating a Pizza Order program as part of my coursework college. why something isn't working.
Quote:
lblTotal.Text = Val(Form2.lblPizzaTotal.Text) + Val(Form3.lblDrinksTotal.Text)
The code above is what I am using to add the Value of Label 1 (Pizza Total) and Label 2 (Drinks Total), however it seems that in the final total it doesn't appear to add the value of Label 2.

I have a VB 2008 program that was converted from VB6. I used an AxMSComCtl2.AxAnimation COM control to show a simple AVI file (no sound) in VB6. Is there a .NET Framework control that I can replace this old control with? I have found the MediaElement that looks like it can only be used in a WPF Application. There is also the Media Player Component which seems to also be a COM component. So, I don't see the advantage of switching to that.
