Extend Program So It Has Subtraction As Well?
Oct 15, 2009
Remember this from before?
Quote:
Since you are repeating same operation three times it is best to make a function for it.
CODE:
labels 1-6 are randomly generated numbers, text boxes 1-3 are the input boxes and the code above shows how if the answer in the textbox equals the labels added together, you win. This code works -
I have created labels 7-12 now, and textboxes 4-6. How can I extend this program so it has subtraction as well?
If this problem definition isn't detailed enough, let me know and I'll add more detail to this description.

I am writing a program that sims a cash register. Everything works fine except VB will not compute subtraction. If I put a replace - with + everything works. What could be the cause of this?
Here is part of the
'Convert input into number
isConverted = Double.TryParse(owedTextBox.Text, NumberStyles.Currency, NumberFormatInfo.CurrentInfo, owed)
[CODE]...
***********If owed is 10 and paid is 5, it returns 0, but if I change the - to either a + or *, it returns the expected value

In my "Select" statement I have this:
Int((Date()-dob)/365.25) AS Age
I would like to do the same thing in VB .NET code. I plan to do something like:
editBoxAge.Text = .......
dob would be stored in datePickerDob.Text

i'm working on a simple 3D CAD to create complex 3D objects. This application uses:
1. Direct3D to render the objects
2.The methods contained in the Mesh class (such as Mesh.Box(...)) to create them
3.The Matrix class to apply some basic transformations (such as Translation or Rotation)
My issue is to do a boolean subtraction of a Mesh to another one to create a more complex Mesh, for example a Mesh with holes.

I have made my calculator and it has 2 textboxes where the 2 numbers (or values go for addition and subtraction) are input and a label where the answer appears. There is other things on the page such as quit, clear etc thats all done but i have one query. I noticed while testing a problem occurs when only one number or value is put into a textbox and a command is hit. For example. one textbox (txtnumber1) has one number in it then i hit multiply and it says the error of course because its not programmed to deal with this (or divide by 0 of course) so i was wondering how i could make so when this happens a MsgBox appears saying a value must be in both boxes or when divded by zero is says something similar.
The line of code:
Private Sub blah blah blah...
If txtnumber1.Text = False Then MsgBox("Please Input Valid Value")
End Sub
I however have not been able to make it work.

I reference several 3rd party libraries in my application. I want to put all of these libraries in a folder that is different than where the executable file for my application is located. I would also like to put all of the libraries that are required by the 3rd party libraries (but not referenced by my application) in this same folder.
I need to be able to put the application (and the referenced libraries) on a thumb drive and run the application from any computer without any installation or registering of components. This condition is satisfied if I put all of the required libraries in the same folder as the executable.
For example, if my application is located at E:MyApp then I would like to store all of the 3rd party libraries in the folder E:MyAppDlls. Any way to store all (or at least some) of the libraries in a separate folder?

I need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.

This has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:
somethiing._DEfault is not allowed here because it does not extend class 'System.Web.UI.Page'
where something is the name of the project in the properties. I have the following code in Default:
Namespace FormDiscovery
Partial Class _Default
Inherits System.Web.UI.Page
Shared settings As New System.Configuration.AppSettingsReader
[Code].....
Now I have deleted the project and other in the solution and created a new one and still this error and if I take the 'something' name away I get the cannot load default error.
