I have been struggling with this issue for like 3 days now. What I need is ONLY a printcopy of a receipt. To do this, I made a template with labels to display respective values(pulled out by SQL statements).

View 6 RepliesI don't want to spam the forum with questions, so I'll just ask a two questions I can't figure out in one thread since they all involve a specific task I'm trying to create I'm trying to make something identical to a map-editor for a game. Right now I'm just learning the basic functions of drawing on bitmaps. I'll show you what I got right now and then tell you what I'm trying to achieve:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim mySource As Rectangle
Dim myDestination As Rectangle
[code]....
So my map size is 1000x1000. When I press the button, it creates the map, draws 250 tiles(pixels) in the top left corner of the map, and then displays it on my form. Now to my questions: How can I zoom into certain X, Y positions on the map? After I zoom into the map, how can I call a function when I highlight a tile(pixel), and then another function when I click on a certain tile(pixel)?
Would there be a way to make the system.drawing namespace available to a console application? ( i know this sounds silly, but all my application does is take a bitmap of a window and saves it to file, so whats the point in my application being form based)
View 2 RepliesIf i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.
I am printing a receipt with the following code:

in this program that Im making I need to print something that the user have saved in a textbox. And the problem is that the text wont auto adjust to fit the paper, it just keep running on the same line outside. I tried to use printsetupdialog to setup the margins but the settings wont apply when printing, here is the code:

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 have a little experience with drawing using GDI+ in VB.NET, but not so much with more complex shapes. All I ever used were lines and rectangles, and the occasional ellipse.I need to draw an 'arc' like this:I can specify the starting angle (0 in the picture), ending angle (angle from the horizontal (left side)), and the starting and ending radius, and I'm sure any other things I need can be calculated from that.The problem is that I have no clue which drawing function to use. Can I do it using FillPath, or FillClosedCurve, or? Of course, I could create a pie shape and then draw a second pie shape (slightly less radius) on top of that to make it appear like it's a single shape, but what if it needs to be 'transparent'? I don't want it to draw a solid shape on top.
View 17 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False

I have made a program in which a small space ship rotates, with some tutorials I found, then when i tried to move it I realized that .location does not work for bitmaps..
View 1 RepliesI have a Custom Groupbox that overrides the OnPaint event to do some custom drawingbackgrounds, etc. The problem I have is that when I use it in an application and want to draw text on the control, it gets drawn first, then immediately afterwards the OnPaint from the control gets called and draws on top of the text. Is there any way to get the text drawn after the control's OnPaint?

View 12 RepliesI have my application to where you can load up an image and draw on it with the mouse left down and drag.Only problem is, if the form becomes the inactive one or is minimized/maximized the drawings go away until I scroll the image in the form (I put the redraw functionality in the picturebox.Paint event).How can I make the lines I draw stay permanently? I've put picturebox1.refresh in the minimizedchanged/maximizechanged and form.activated events and still nothing..Even tried the picturebox's resize event and nothing?

my assignment is to draw a graph within my VB form with a some variables I have. I was told by my boss that I should use Microsoft Chart Control 6.0, but I don't think it matters if it is in another software.I currently have a few variables, each with a lot of values, "Frequency", which is user entered from maximum to minimum, CH (channel) 1-4 which are given by a machine output I use at my company. My graph, is supposed to have the Frequency values in the X-Axis (horizontal) and the CH 1-4 values within a range of each other in the Y-Axis. Can anybody help? My code for extracting the data and getting the frequency is below. How I got most of it is thanks to Stanav, the thread is over here: url...It comes with 3 buttons (I have not put in the code for button 3), the 3rd button will be used for plotting the graph when clicked.

I've got a fun little question for you all. I am designing a program that allows you to click on a picture to input data in certain areas. What I want to do it pretty allow someone to take a look at a picture. Click the add point tool, then select an area on the picture where it places a circle. I then want them to be able to go back to the circle and modify data if necessary
