View 4 RepliesI'm working on a calculator application and one function is to find midpoints on a cartesian coordinate system. I have inputs for two x and two y coordinates , and the program calculates the midpoints of both and prints them in a text box as a new set of coordinates. The points are represented by doubles to allow decimal and negative points, but I want to round the final coordinates to 1 decimal place. e.g: (12.5, 9.8) Math.Round would work, except that it only seems to be able to round to a whole number. e.g: (12, 10)
Is there any way to specify how many decimal places Math.Round rounds to, or is there another function that could acheive this result?

Working on some UI stuff, but I am having a problem drawing 'Top rounded' rectangles when the two top corners are rounded. I have methods to draw all four corners rounded and bottom rounded rectangles and they render fine.
I have attempted the graphics methods in CreateTopRoundedRect() in a variety of different orders, drawing the other corner first, the bottom line first, the bottom line before the left line, etc. In this function you can see a diagonal line splitting the shape. If you were to switch the bottom and left lines only half of the shape would be filled.

View 12 RepliesI have two textboxes that will contain numbers.I convert those text boxes to integers and then want to multiply them by certain values and then show the new value in a different textbox.For example,100 gets converted to an integer and then multiplied by 1.75 and the value displayed in the other textbox is 200 instead of 175.How do I make it so the value isn't rounded to the nearest 100? Here is my code, compTotalPremium.Text and collTotalPremium.text are the boxes that are showing the rounded value.
Dim Comp As Integer = compDedPremium.Text
Dim Coll As Integer = collDedPremium.Text
Dim CompMulti As Integer = compDedMulti.Text[code]....

View 5 RepliesEvery sample code I've ever found for drawing rounded rectangles using GDI+ goes something like this (lifted and slightly modified from BobPowell.net):

e.Graphics.Clear(SystemColors.Window)
e.Graphics.SmoothingMode = SmoothingMode.None

This produces a rounded rectangle where only the top left corner is accurate.AntiAliasing has to be turned off because it is going through a remote desktop connection, and I can't depend on it being available. Besides, I am looking for a crisp rounded rectangle.I've tried resizing the other corners and changing the pen alignments, but nothing seems to produce a simple, accurate rounded rectangle.Is there a way to draw a better rounded rectangle than this in good old winforms?
I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

View 2 RepliesI am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:
Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:
[Code]...
Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)
actually when I edit float value in datagridcell , I want only two numbers to be displayed after point(.)....i.e 2.35 instead 2.34567 more over am getting it but the actual thing is that value is not getting update in the dataset , but when I reload the form it shows like 2.34567 only instead i want 2.35...

View 3 RepliesI need some help importing data from Excel 2003 into VB10. My goal is to import the data and save it to a 2D array for later use within the application. The data is on sheet 1 of the workbook and goes from A1 to D1072 with a header row. I have done a lot of research on line to find a solution but have been unsuccessful. From what I have found I have put the following code together. When I complile and run the program I get the following errors.
1) I think while compiling it gives me this error: The source file is different from when the module was built.
2) While running the program it stops on the connect.Open() and has this error OleDbException not handled. Could not find installable ISAM.

I have read about Round() and MidpointRounding.ToEven but I still could not figure how to use it to achieve what I want. I have numbers (usually from 5 digit decimal) such 125.36 , 125.10, 125.99. I want to make the 2 decimal point rounded to the nearest 20. Means, the 2 decimal point should be either .00 or .20 or 0.40 or .60 or 0.80 only.
125.36 should be 125.40 : 125.10 should be 125.00, 125.99 should be 126.00
125.54 should be 125.60 and so on
Is there math function to make or I should parse the number as text and test the last 2 digit?
Why vb prints out 1??? when d is a double aproximation to 1? shoudnt be 0.99999 or something similar? what if I really need the float value? and how could I print it?

I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?
I would like to create a no border form (i know how to do this), and make the corners rounded off, kind of like you see in iTunes, the form has rounded edges. Can someone help me with this?

Why my math keeps getting rounded to 0 decimal points by default?When I do this I get return value of 1

How to get that value up to two decimal points (like 0.00)?
I know how to create the Rounded Rectangle, but what i don't know how to do, is make the area outside of the rounded rectangle (the corners) become transparent This is going to be used on a usercontrol, so i really need it to be transparent and not just blend in (ie adapt to the colour of the parent form).

I am trying to put together a booking system. I have managed to program rates, discounts etc., and am now onto calculating the nights for the stay. On my form I have two datetimepickers, and a button. The code I have entered is: (I am using Visual Basic 2008 Express)
CODE:
This works well when getting how many nights between two dates in the same month, but if I enter say 30th August to 2th September, I get a -28. Is there a way to get the number of nights booked between two different months?
