What's the difference between Console.WriteLine() vs Debug.WriteLine()?
View 3 Repliesi've been doing research about this for a while now. I'm pretty sure it's correct, but the console.writeline is not providing any messeges when program is executed. Im using Visual Studio 2010 pro. Is there anything im missing or doing wrong? Here's what i have:

It would be handy during debugging to have multiple consoles (not multiple monitors, which I already have). I am imagining something like Console.WriteLine(1, String1) which would send String1 to one console window 1 and Console.WriteLine(2, String2) which would send String2 to console window 2.

i would like to see what the console is writing. how do i do this?

I have declared my variables As Decimal, and what I am struggling to do is to display these values to 2 decimal places in such a way so that they both appear on the same line of output. Here is the guts of the problem (noting I have two different versions of Console.Writeline...the second one does display on one line, but without two decimal places).
[Code]...
I'm working on a console application that needs to write a line until a certain value is met and than do the same backwards until another value is met.
The line need to be 51 spaces wide, start and end with the pipe ("|") character and have a cross ("X") character in between.
I can only define both the characters once.
The result needs to be something like this:
|X_________X|
|_X_______X_|
|__X_____X__|
|___X___X___|
|____X_X____|
|_____X_____|
And then from the last line on, go back to form a big X on the screen and start over again, going over and over until a key is pressed.

Is it possible to have a Msgbox without a button on it in a console application. I would like to have a msgbox pop up and then disappear when the task has been completed. Or could I send the msgboxresult to some form of window that would just disappear when the file has been written? [code]

View 12 Repliesin VS 2008, I started a new VB console project, using default options. I wrote this simple program:
Module Module1
Sub Main() Dim ArrayOfInts() As Integer
ArrayOfInts = New Integer() {1, 2, 3, 4, 5, 6, 7, 8, 9}
[Code].....
However, I cannot find the output from the calls to writeline. Not in the Output window, not in the Immediate window and not in the console output.
Or, do I need to do something extra to get these to appear?
if its possible to have a msgbox cleared without having the user do it manually? what would be my best option here?
View 8 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?

I have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?
View 2 RepliesWorking 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 Coll As Integer = collDedPremium.Text

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?

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?
I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).
