I want to draw a string at a specified location with a specified width. If the string is wider then the specified width, the string is "word wrapped". How can I find out how much vertical space was used (the height of the "word wrapped" string)?
e.Graphics.DrawString(strMyLongString, Me.Font, MyBrush, MyRectangle)
What I am trying to do is rotate a string (or rectangle) 45degrees and find the new height and width after the string has been rotated.
Basically the width and height of the rectangle draw area the new 45degree string takes.
My task for the moment is just to find out what the height of ListView's data row is (not the header--different height). The height of a ListView meant to fit exactly the contents of the list can't be set statically. This is because, when a system uses font scaling, the ListView rows are going to be scaled relative to the scaled font. So, I have to find out what the height of the first row is (since they're all the same height) and then multiply that by the number of items in the list. This should get me an exact fit for the height of the ListView.

I can get these values by setting an ASP.Net hidden input control using javascript, after the page has loaded and a post back is done. I need to be able to get these values when the page initially loads so I can create an image based on those values.

I am working on a report in Excel and there's potential for quite large amounts of text easily over-running a merged sell of maximum row height size. I therefore want to be able to merge the right amount of rows to make the text fit cleanly.My idea was to try and find the height of a string when limiting it's width - essentially placing a piece of text into some kind of container, making that container fit to size (with a set width limit, in this case 640 pixels), and measuring the height of that container. With the height of the said container, I could then work out the amount of standard sized excel rows I want to merge.I tried to use a label but there's no way to set only the vertical element to be autosize.

Got a dll from a supplier that I need to call. His declaration is Declaration with Microsoft Visual Basic: [code]Now, the Sting * 20 is clearly not VB.NET, and sure enough it crashes when run - "Attempt to read or write in protected memory" and that leads me to think that there is something with that string definition - or possibly the I_Ref definition which hasn't been defined as fixed length.I've tried <VBFixedString(20)> when defining O_Err, but I have a feeling that it might not be enough when the function declaration is like that (not specifically fixed length). I cannot figure out how to specify this correctly.As a small hmmmm, the above is pasted directly from the suppliers documentation, but that't will never work, as there is a "," missing after I_Range as long... Clearly not something he has pasted from a working program.

In VB.NET, it is entirely possible to pass an integer as a string parameter to a method without calling .ToString() - it's even possible to call .ToString without the ()'s. The code will run without a problem, VB will interpret the integer as a string without having been told to. In C#, these would cause compilation errors - you are required to call .ToString() and to call it correctly in that situation before it will compile. Is there a way to make the VB compilation process check for the same things as the C# compilation process? Would it be best practice in a mixed team to force this check?
