m trying to calculate the width of a textbox given x number of characters. So how, given a random instance of a textbox and a random number of characters, can I calculate this? little extra spacing is allowed - for example if you were basing the widthupon the greatest width of a character given the current font. Actually, this is preferable
View 4 RepliesI am creating a puzzle game and would like to calculate the width and height of the puzzle taking into account the original image size and the screen resolution. My screen height is 768 and width is 1366. An example image is 1200 x 1600 and the jigsaw size that works well with this image is 480 (height) x 640 (width). I would like to create an algorithm that calculates the jigsaw size for any image bearing in mind that the screen resolution will change as will the size of the image.

This Winforms app has a toolStripComboBox within a MenuStrip container that displays Culture Info languages.The toolStripComboBox's width is not expanding to accommodate the size of the string. The strings are dynamically added to the combobox from underlying code. How do I get the comboboxe's width to expand? Below is an image of the'too narrow' combobox and below that the Properties for the combobox.

I have a drawing program written in VB6 that is capable of printing very thin lines to a laser printer. In VB .net, even though the pen width is set to 1, the thinnest lines are way too "thick". The equivalent line width in VB .net using a pen width of 1 is about the same as the DrawWidth = 4 in VB6. So, my question is, how can I print very thin lines to a laser printer in VB .net?

I'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
So I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the code.
