C# - Convert The Font Size In Inch?
Mar 23, 2012I need to convert between Drawing.Font.Size (float, ?) and WPF FontSize (double, WPF pixels).Finally, I decided to store in the database the fontSize in inch...How can I convert the GDI FontSize to inch and the WPF FontSize to inch?
sizeInInch = wpfFontSize / 96
sizeInInch = gdiFontSize / ?
Can I use something DPI independent? Maybe System.Windows.FontSizeConverter?I need to convert to something, that will allow me to switch multiple time between WPF and GDI without changing the "real value". Each division and following multiplication will accumulate errors...
FontSizeConverter does a ConvertTo, but I don't understand to use it:
myUniversalFontSize = (double)(myFontSizeConverter.ConvertFrom(
gdiFont.SizeInPoints.ToString() + "pt"))
will transform my gdiFont size in ...? WPF Pixels?How now should I convert back that value to GDI?
gdiFont.SizeInPoints = myUniversalFontSize / 96 * 72???
Can I use in the second example the myFontSizeConverter too?

I was thinking I need to strip the decimal places and then compare them to a dataset of numbers a make a choice?

VB 2010 - Binged My Browser To An Inch Of It's Life?
Jan 22, 2011I've googled and binged my browser to an inch of it's life, but i'm still no nearer to an answer for this, so I'd be grateful for some advice. Mainly with the syntax, but knowing me the whole concept is wrong!I have a textbox. When user enters a string and presses enter, I want the following to happen.
I'm struggling with 3 and 4 and 7
1. Check the string is not more than 13 characters, if so trim the last characters off to make 13
2. Find if the first character of the string is a digit or a letter
3. Convert the string into an array of INT

VS 2010 - Bitmap Pixels Per Inch/Centimeter?
Mar 10, 2011I have scanned a few img's on 600 DPI. When i load them into a Bitmap class They have Vertical and Horizontal Resolution of 96 PPI To my calculation that is very close to 38 Pixels per centimeter. Now the image that I scanned is 4.5 Centimeter (1.77165354 Inch) In Diameter but When I measure It the 4.5 cm img is close to 1080 pixel in Diameter which is 240 Pixels/Centimeter (609.6 Pixels/inch) What is the correct way to get the actual Pixels per inch/centimeter from a bitmap or was it set incorrectly by my scanner ?

View 5 RepliesC# - How Expensive Are Dots In .NET
Aug 27, 2009In the past, in C and C++ land, nested pointer dereferencing was considered, by some, to be a relatively expensive operation if executed in a tight loop.You wouldn't want to get caught with:
for (int i = 0; i < 10000000; i++)
{
j->k->l->m->n->o->p->dosomeworknowthatwereherewhynoteh();
}
because you might lose precious milliseconds. (Yes, I'm being somewhat sarcastic!)

Printer Stuff - Detect If My Printer Is Busy ?
Mar 18, 20111. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

View 3 RepliesInterface And Graphics - Plot Points And Joint The Dots
Dec 12, 2011Picture 1 shows an application that I am currently writing that uses the LineShape and OvalShape out of the Visual Basic Power Packs. As I change the index in the part number combo box the A, B & C dimension change to suit the dimension in the text boxes.
Problem is the limited shapes are fine to draw a router template guide, but they are somewhat limited when it comes to drawing more complex shapes like the router bits that make the shapes in Picture 2. Is there a graphic class that would allow me to plot points and joint the dots like you get in kids colouring in books? Or something a little more adept to complex shapes like curves?
I just spotted something called the Pen Class that I might need to look more into, but not knowing the first thing about graphics. Spotted some advice passel gave in another thread to search vb.net gdi+ tutorial and it looks like the Pen Class might have potential, although I am going to have to revisit some math by the looks of things.

View 5 RepliesDrawing Dotted Path Lines With Evenly Spaced Dots?
Apr 22, 2012I have a problem drawing dotted path lines, with evenly spaced dots: I want to be able to draw evenly spaced dots along a path line using points in an array, My issue is not with drawing the path line, with dotted lines, this is easy, but with the spacing of the dots at the start and end of the path line.
In the example I have created, I create a square with 4 points and draw a dotted path.The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have.I have also attached two pictures showing the dotted path line, 1 with even spaced dots at the start / End and another showing the problem I want to resolve, with not evenly spaced dots at the start / end.The only difference between the two is the point values.
Finding A String Between 2 Other Strings That Has A Minimum Length Of 5 A Maximum Of 7 And Contains 2 Dots
Oct 5, 2011What I need to do is find a string that can be any value, and is placed between ">" and "</" with a minimun length of 5 and a maximum length of 7 and contains exactly 2 dots.
So if I have a text file like this:
<a href="www.site.com">a site</a>
text<br />
More test<br />
[Code]....
I want it to find only the 5.0.77. And no, the number isn't always between h2 tags, and the number isn't even always the same. The only thing that is static about it is that is is between ">" and "</" and that it is between 5 and 7 characters and contains 2 dots.

Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.)
