TextRenderer.DrawText Rectangle Area Offset For BorderStyles
Dec 5, 2010
Drawing text on a picbox I notice if the picbox has a border style set then the TextRenderer.DrawText rectangle area needs to be adjusted slightly otherwise text may be drawn very near the picbox borders and the text doesn't look as clean, but I'm not sure what those offsets should be, I hard coded them in, see code under "' area to draw". btw, the code draws the first word of text in bold and then the other words as regular. 'One button, One picture box needed.

I want to use the added functionality (for word wrap etc) of the TextRenderer.DrawText method.... but this does not seem to work correctly on the Graphics object in the PrintPage event in the PrintDocument Object and does not take into consideration any transformations that have been applied. Does anyone have a replacement way or workaround for this?

I'm using some code to enable me to render rotated text with the TextRenderer.DrawText method. (By default, DrawText can only copy a straight forward x and y transform from a graphics object).
The code (C#) is from: connect.microsoft.com. See below for a VB conversion.The code takes a graphics object, creates a device context and copies the transform matrix from the graphics object. It works, but I'd like, also, to set the TextRenderingHint, so I tried:
<DllImport("gdiplus.dll", CharSet:=CharSet.Unicode, SetLastError:=True, ExactSpelling:=True)> _
Public Shared Function GdipSetTextRenderingHint(ByVal graphics As HandleRef, ByVal textRenderingHint As System.Drawing.Text.TextRenderingHint) As Integer End Function And then after the SetClip statement, I place: GdipSetTextRenderingHint(hDC, someHint) This gives me a memory access violation error, so I think I should be using something other than hDC as the argument.
I can get it to work by creating the device context from the original graphics object, and then creating another graphics object from the device context. I then set the hint on the new graphics object. This seems a bit convoluted so I was wondering if it was possible through interop.

I've been working with System.Drawing for awhile and like to think I have a good handle on it; I've created classes that draw grids, write text in gridboxes and rectangles, convert rectangles to circles, fill areas with color, etc. What I don't have is any sense of artistry at all, and I don't have the slightest clue how one would use System.Drawing to draw a rectangle and then color/slope the edges so that it looks like a System.Windows.Forms.Button would, or how to make it look like it's inset deeper than the surrounding Form, like setting a Panel's BorderStyle to Fixed3D.

OK, so I just started this VB programming class at school. But I don't understand much because the teacher doesn't really teach us. He just types everything on the projector and expects us to keep up. We have this project in which we are supposed to build a form that accepts the length and width of a rectangle, and calculates the area and perimeter of the rectangle. CAN SOMEBODY PLEASE HELP ME?? I really have no clue how to do this, and more than half the other people in our class don't either, so finding help within the class is pretty much out of the question.
The user enters values for the length and width of a rectangle and clicks the Calculate button or presses the Enter key to activate that button. The application then displays the area and perimeter of the rectangle in the third and fourth labels on the right side of the form.
Specifications The formula for calculating the area is width * length. The formula for calculating the perimeter is 2 * width + 2 * length. The application should accept fractional decimal entries like 10.5 and 20.65. Assume that the user will enter valid numeric data for the length and width.

I'm writing a .NET program for an engineering company. Their specification is to find the number of holes (either of same or different radius) on a rectangular plate and then to find the area of the rectangle and also area of the circle inside that rectangle. It's not essential that the circle touches the rectangle.

Given a rectangle of width w and height h. and a coordinate x,y in that rectangle I would like to identify which triangle I am within.
i.e. the function should take parameters(x,y) and return a,b,c,d or a zero based number representing that triangle index i.e. (0=A,1=B,2=C,3=D) if they are in that order.
I think this would be something like >= the formula of the red line and >= the formula of the green line?
I'd like to implement this in VB.NET

Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.

I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

why Graphics.MeasureString is so different to TextRenderer.MeasureText?
vb
Dim SizeG = e.Graphics.MeasureString(New String("i"c, 100), New Font("Microsoft Sans Serif", 8.25, FontStyle.Regular))[code]...
I realize that one returns SizeF and the other Size... but the results are over 50px different in the width ?

I'M creating a kind of photo viewer, and I cannot figure out how to orient the scroll buttons with the photos I want to draw because they all are different sizes.This is really hard to explain so please ask questions if you don't understand.I'M thinking if i could draw every photo on a single rectangle and then the scroll bars will position that rectangle up or down. but is there a way to make a rectangle inside another one so it only shows inside that rectangle?

I have an app with clocks on it from around the world. It's used in multiple locations around the world as well, some that observe DST, some that do not.
Is there some way to get the current offset for various timezones from the OS? My preference would be to simply use the OS to GET the offsets, thereby relieving the program of having to figure out the dates and when to reset the clock. That would eliminate the need to be concerned with DST altogether; the offset values could simply be added to the current datetime.utcnow. I'd need to get the offset/current time for Hawaii, Pacific, Mountain, Central, Eastern, UK, France, Germany, Mumbai, China and Australia time zones.
TimeZoneInfo.GetSystemTimeZones can get at some of this data; is there maybe a way to cull it out of that?

I've drawn a graph where each gridline represents 15 minutes. (Every 4, 1 hour of time)The resolution is 100 dpi per inch. Each column is 12 DPI. (Not very big)Each gridline can have zero to multiple "Lines of data" which must be centered under the associated gridline using a vertical transform. (Each drawtext label represents an event that happened at that point in time)This I can figure out. The problem is that there can be 3 labels at 3:00AM, then another 2 labels at 3:15 AM with more labels as time progresses through the day. If each "label takes up 24 dpi of space, I need to center 120 dpi of data under 12 dpi of space.(Drawing the lines from the gridline to the associated data should not be an issue depending on how the "label is centered)How can I center all 5 labels at runtime. I've considered an array but each time a "label" is added, I would have to recaculate each labels position. Besides that, how can my program recgnize that the data it is coming up to (data is read one line at a time) is a group or how large the group is?

How can I get the sum from richtextbox, starting at line -1 ? But the first line should compare with line1.This code adds a constant to all lines and passes the sum to another textbox.
Dim num1 As Single
Dim sum As Single
Dim Constant As Single = Val(txtLowerTol.Text[code]....
So a third textbox should sum with one line "offset".
