Printing Arithmetic Functions - Drawstring Command ?
May 1, 2012
A recent assignment asked me to write a program to print a business expense report. The example form showed both a print and a print preview button so I assumed that meant not to show my output in a listbox. The problem that I had is I kind of ran into a catch 22 situation. If I declare some of the variables as strings, then I can't get the program to perform the addition arithmetic, it wants to only concatenate. If I declare them as integers or double then I can't get them to be recognized by the Drawstring command. The strange thing, to me as a beginner anyways, is that it did perform the arithmetic on a variable (meals) that I declared as a string initially. It multiplied it by 50% as I requested. If it wasn't for the concatenation, this would have worked perfectly according to the assignment.
The code is below:
Public Class frmBusiness
Const One_Inch As Integer = 100
Const line_height As Integer = 25

I must convert string data from a CNC that is arithmetic expression to a number that I can use in a VB application that I wrote. The following is what I get out of the cnc. [18722*65536+19377]/67108864. I need to evaluate this expression in my VB ap. The format of the string is not always the same as what I have illustrated.

What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).

1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.

I am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.

I'm using graphic.DrawString to well... draw a string.I specify the Font Family, Font Size, Font Style, Graphics Unit.Everything works well for 50 computers but for just one, the font is "bolder".The characters are the same height but for some reason the "pixel" are double the width.Can this be fixed with code?Can this be fixed using a windows setting?

I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.

I'm creating an application which has an scheduler to print and it checks if there is a pending job on the print queue before it prints the next file. I use a timer which checks if there is any file to be printed on my database. Example, the timer ticks and selected 10 files to be printed, it should print the 10 files 1 at a time, if there's no print queue, that's the only time the next file should print. I think another timer is required which will keeps on checking if print queue is done. How will i do this?

First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.
I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _
ByVal lpClassName As String, _
ByVal lpWindowName As String _

I'm confused on this because this works fine in VS 2008 on winXP sp2/sp3 but in VS 2008 on Vista sp1/sp2 I'm getting an Invalid Parameter exception on this line:
e.Graphics.DrawString(aColor.Name, Me.Font, br, e.Bounds.Height + 5I, ((e.Bounds.Height - Me.Font.Height) 2I) + e.Bounds.Top)

I have noticed that when I use drawstring to only print numbers, it just prints nothing. However if I put a letter in the string, it prints. So, "12345" will not work, however
"a12345" will work.
Example:
Dim g As Graphics = e.Graphics
g.DrawString("12345", myFont, getBrush(Color), X, Y)

While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?

Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.

I am using drawstring with the DrawMode set to OwnerDrawFixed on a tab control. The Tabs have a alignment set to left, but the text is displayed in a horizontal orientation. I would like to change the orientation to vertical. I am expecting this to be simple, but can not seem to find the correct input parameters for drawstring.

Here's the OnPaint method of a control that simply inherits from control and provides a property to get/set the textrenderinghint:
Private _mode as TextRenderingHint = SystemDefault.
Public Property Mode as TextRenderingHint

I've never seen this error before; and apparently (According to DIC) the number would have be bigger than -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, to this this exception (I'm using an Integer, but I've tried Int64, and the same thing happens).
This is where the exception is being thrown:
Dim localPort As Integer = (tcpRow__1.localPort1 << 8) + (tcpRow__1.localPort2) + (tcpRow__1.localPort3 << 24) + (tcpRow__1.localPort4 << 16)
Full Code (Method)
[CODE]...
I highly doubt that that the integer that is being parsed back is greater than, either of those numbers listed above. I've tried using Int64, and even removing the << operator, but it's still throwing this exception.
