NET Printing Coordinate Conversion?
Aug 23, 2011
I can't get a simple answer to this. I have pixel coordinates, I want to print an image in a (landscape) page at those coords.In my printing event I do:
Dim mypoint As New PointF(1, 1192)e.Graphics.DrawImage(My.Resources.littleSquare, mypoint)
This obviously doesn't work: I specify pixels but the driver expects inches(?) or what?
Tried to: e.Graphics.PageUnit = GraphicsUnit.Inch with no luck.I'd like a conversion method like:
Dim mypoint As New PointF(convertPixelsIntoInches(1), convertPixelsIntoInches(1192))
e.Graphics.DrawImage(My.Resources.littleSquare, mypoint)Private Function convertPixelsIntoInches(ByVal pixels As Integer) As Single

I am currently making a 2d game where a spaceship flies around a 2d map.Currently, I am moving the ship with keys, but would like to implement mouse clicking as well.I am wanting to enter an x and y coordinate and have the ship move to that coordinate.
These are my variables:
PlayerFacingAngle, PlayerPositionX, PlayerPositionY, PlayerVelocityX and PlayerVelocityY

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 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?

a user will enter a number, n, which ranges from 1 to 30. they will also enter a "P" or an "S" (sum or product). depending on which was selected, it will calculate the sum or product of the numbers from 1 to n.i'm having a conversion error on line 5 stating "Conversion from string "S" to type 'Double' is not valid."

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.
Here is my plan:
Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.
Completed: (VB.net) Monitor folder, when text file is added begin processing
Not Complete: (VB.net) Import text file to Excel
Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)
Completed: (VB.net) Save file.
Completed: (VB.net) Send file to list of recipients.
Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.
The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?
Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?

I have a chart on a Windows Form with several line graphs. I would like to be able to get the x-coordinate from a mouse click on the chart in such a way that the user would be able to place vertical annotations on the chart at the location of the click. I looked at the Chart.HitTest function, but that will only do what I need if the user clicks on a data point, not anywhere in the chart area.

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
Label5.Text = "X:" & e.X
Label6.Text = "Y:" & e.Y
End Sub
Dim objectrect As Rectangle = rects(0)
Dim object_x As Integer = objectrect.X
Dim object_y As Integer = objectrect.Y
Label7.Text = object_x
Label8.Text = object_y
I discovered that these labels are not the same, the mouse move is more accurate. My mouse is currently pointing at the upper left corner of rectangular.

When I print the output to a PDF file using PDFCreator, it stacks all of the letters onto each other rather than creating new lines at the places I've specified. I've also tried using vbNewLine instead of vbCrLf, but I haven't had any luck. I searched the web for this but couldn't find anything about it.

I have a question on the best way to store model data for my app. My app will basically be drawing a bunch of elements (lines) connected to a node at each end. Im trying to decide how im going to store my node data (as well as element data). The node data im trying to store will consist of the node XYZ coordinates and some other info about the node. The element data will consist of the node numbers at each end plus additional info about the element. There a number of ways i've been thinking i can do this. They are:
1) Store my node/element data as a Dictionary object, where the key represents the node/element, and the value would be an array of the information i want to store.
2) Create a "Node" structure and an "Element" structure to store the info i want. Im a bit worried here as my model could potentially have thousands of nodes and elements.
3) Create a "Node" datatable and an "Element" datatable, and store my info in those instead. I can see some advantages in this in regards to displaying information to the user in datagridview etc. But then again i can easily pull the required data from a method i mentioned above, and generate the datatable when required.
Not quite sure what the best approach is. Either way i do it, i will be serializing whatever object i use to save the data to disk.

i am having a problem in building up a VBcode for getting the minimum distance between a set of coordinate points. what actually i an trying is to find the minimum distance between one set of coordinate points(A(x1,y1),Bx2,y2),C(x3,y3),D(x4,y4),E(x5,y5)) with respect to another set of CO-ord points (i(x1,y1),j(x2,y2),k(x3,y3),l(x4,y4),m(x5,y5))..
ublic Function DoSearch(ByVal SearchCritera As Bracket, ByVal ListToSearchFrom As System.Collections.Generic.List(Of TRacksDefinitions.Racks.Bracket)) As System.Collections.Generic.List(Of TRacksDefinitions.Search.SearchBracket) Implements TRacksDefinitions.Search.ISearch.DoSearch

the above is code which i have created till now and the next step is calculating the mindistance criteria..search criteria . rear points is the one we get frm solidworks and b.rearpoints is the one present in database we compare both of them find the one which is very similar to the one in database..

I'm very new to Visual Basic, and have just installed VB Express 2008 from a Sams book titled, "Teach Yourself Visual Basic 2008 in 24 Hours", by James Foxall. I've managed to make it through most of the book, which was very helpful in getting a quick jump start, but I find that I am still "not quite getting it" yet.
I've written a program that has a "Start" and "Stop" button which are suppose to control the logging of data through a serial port. When I click the Start button, the serial port gets initialized, opened, and then I go into a Do-Loop-Until loop to process the incoming data stream, and that is suppose to stop when the Stop button is pressed. However, I haven't figured out how to implement that.

I would like to get 3 point coordinates on mouse clicks and get them display in the text boxes. I'm working with my project. An image will be loaded in a picture box and the image has 3 reference point. I need all the points coordinate to be display separately whenever user click on the points. When user click on the first point, the coordinate of the point will be display as point a, click on the second point,the coordinate will be display as point b, and click on the third point,the coordinate will be display as point c.
