im trying to make a a rogram that will calculate the area of a rectangle based on the lenght and
width given by the user
[code...]
I am trying to implement a controlling design logic that prompts the user for a length and the area to calculate until he or she enters a number less than zero in the length to end.So far I have it where I believe it�s doing the calculations but it�s not ending when I input a number less than zero or zero.
Sub Main()
' Declare Length As Float
Dim Length As Double
' Declare s, c, t As Float

Since we have to resize the combo box dropdown area based on the combo box item length, used the drawstring() to add items to combo based on the item length. This gave us the below issue: On moving the cursor on the drop down area the font color and the background color are back hence the text is not readable (i.e. the whole item becomes black).
Below piece of code is used to achieve this,
Private Sub cboClient_DrawItem(ByVal
sender As
Object,
ByVal e
As System.Windows.Forms.DrawItemEventArgs)
[Code] .....
We tried changing font color and the dropdown area backcolor on selecting a particular item. How to make the text readable (i.e. the font color should change while if we scroll on the item).
I am using the following code to place a rectangle around a form / form control, however what I want to do is make my screen grey and only the form / form control area be displayed in colour.

I am creating a program for which will calculate the time taken for a user to make a number keystrokes. I want to start the timer running from the beginning of the first key stroke and end on the final keystroke. Each keystroke has been linked to a label which will change colour according to whether the key has been pressed. When the keystrokes have been finished I want to save this timespan in a field in a database. To test that the timer is running I have made a messagebox which will show the time taken however it is constantly showing zero and the label for the final keystroke is remaining in the keydown colour.

What I am trying to do is fill the contents of the datagridview with the cell contents. There are two ways to do this.
1) Either set the DGV width to the cell contents width, or
2) Autoadjust the width of the cells to the width of the DGV.
how to implement either of these two approaches?
OK, so I just started this VB programming class at school. But I don't understand much because the teacher doesn't really teach us. He just types everything on the projector and expects us to keep up. We have this project in which we are supposed to build a form that accepts the length and width of a rectangle, and calculates the area and perimeter of the rectangle. CAN SOMEBODY PLEASE HELP ME?? I really have no clue how to do this, and more than half the other people in our class don't either, so finding help within the class is pretty much out of the question.
The user enters values for the length and width of a rectangle and clicks the Calculate button or presses the Enter key to activate that button. The application then displays the area and perimeter of the rectangle in the third and fourth labels on the right side of the form.
Specifications The formula for calculating the area is width * length. The formula for calculating the perimeter is 2 * width + 2 * length. The application should accept fractional decimal entries like 10.5 and 20.65. Assume that the user will enter valid numeric data for the length and width.
I am currently working on image cropping software. Any idea how to make image under rectangle to be clear and outside area translucent?
View 5 RepliesI'm writing a .NET program for an engineering company. Their specification is to find the number of holes (either of same or different radius) on a rectangular plate and then to find the area of the rectangle and also area of the circle inside that rectangle. It's not essential that the circle touches the rectangle.

Drawing text on a picbox I notice if the picbox has a border style set then the TextRenderer.DrawText rectangle area needs to be adjusted slightly otherwise text may be drawn very near the picbox borders and the text doesn't look as clean, but I'm not sure what those offsets should be, I hard coded them in, see code under "' area to draw". btw, the code draws the first word of text in bold and then the other words as regular. 'One button, One picture box needed.

View 3 RepliesI have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.

if you want to make program to calculate the result of brackets math question , as 6+(9+(5-(1+(2+1)))) , and you made 2 buttons representing ")" and "(" , and you want when the user clicks on the "(" button it just applies that the number before it to be stored in a place like a label such that the program calculates numbers after it and then calculate the produced number and the label number , something will disallow you that the questions with many brackets as the mentioned one above 6+(9+(5-(1+(2+1)))) will for example store 6 and plus sign in a label but after that 6 will be placed by 9 because there is another bracket after 9 , so the question will be calculated false , more clarification for my question is the way brackets are made in the windows calculator so i want a coding idea to make the brackets like in the windows calculator

I 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.
View 2 RepliesIs there a way to make one list box dependent on the other based on user input. Here's my situation: A teacher has the ability to enter the name of the student into a listbox via a textbox. The teacher may then select the student from the first student list box and input grades that would go into a grade listbox. If the teacher selects another student from the student list box, the grade listbox would either go empty or show the grades inputed for the other student; all the while retaining all previously recorded grades for other students.
