What Size Does The CInt Convert To
Jun 3, 2009I must not be using the proper search terms.
Convert.ToInt32 obviously is a 32 Bit Integer
Convert.ToInt16 obviously is a 16 Bit Integer
So what Size does the CInt convert to?

Convert Font Size To Control Size?
Aug 10, 2010I'm writing a couple of custom controls in VB.Net 3.5, in VS2008, and would like to resize the font size based on the height of the control, and vice-versa. Is there any way of converting a font of say 38.25pts into a me.height, or the other way round?
I realise the font width will change dependent on the font used (which isn't an issue for my purposes), but as far as I know, the font height is usually consistent Accessibility/Large font settings won't be an issue with this application.
Why Is It That The Cint() Is Only Used For Pic.GetPixel(X,Y).R) And Not For The Others
Jul 22, 2011i need some help on explaining to me whats going on in the code below. Basically, the code below is used to convert a bitmap image to grayscale level (black and white).
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim pic As Bitmap
pic = picVisible.Image
Dim X As Integer
[code].....
what i dont understand is the part;
color = (CInt(pic.GetPixel(X, Y).R) + pic.GetPixel(X, Y).G + pic.GetPixel(X, Y).B) / 3
why is it that the Cint() is only used for pic.GetPixel(X,Y).R) and not for the others ? Any Image processing expert that can help explain this ?
Note: The code works well and manages to convert an image into its grayscale.

View 1 Replies.net - Double To Integer Conversion Concerning CInt And Rounding?
Oct 7, 2011I'm quite a newbie in VB.NET (and VB on the whole). So my question could sound rather odd, but still. I've stumbled upon an issue with the CInt and converting a double to an integer.
The issue is the following: CInt(10.5) would be 10
CInt(10.51) would be 11, but I expected 10... (Got used to C# style conversion: (int)10.51 would be 10)
As pointed out here Integer.Parse VS. CInt the result is just rounded in some fashion. Nowever, all I need is to get only integer part and throw away the fractional one. How can I achieve such type of conversion in VB.NET? After a short research I assume that I can use Fix() funciton to do the trick, but is it the best choice ever?
.net: CInt Returning -1 On A (seemingly Valid) String?

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?

Mar 31, 2010I have build a DLL with COM enabled. In this DLL I have classes that did use the functions CInt, CDec and IsNumeric. If I test these classes from a .NET application then it works ok. But when I called/run these classes from a Win32 application (with COM) then I did get an "E_UNEXPECTED(0x8000FFFF)" error.After some debugging I found out that the problem would go away if I:- replaced IsNumeric with Integer.TryParse or Decimal.TryParse- replaced CInt with Integer.Parse- replaced CDec with Decimal.Parsey.

Jul 16, 2009when I click the Open button a file is opened and its items are sorted alphabetically. to do this I have doubled the size of my list. However, when I click the button again to reopen the same file, the items will ADD ON to the previous open-file event even though I have this piece of lstListboxTwo.Items.Clear()(the correct thing is to clear the previous items and add the new ones)So I think this has to do with the new size of my list..I think that I have to set the list size back to its normal size when re-clicking on the button.

VB 2008 Express/ Webpage To Fit The Size Of The Webbrowser1 Control Size?
Jul 13, 2010I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the
size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web
(or local) fill the size of the webbrowser - almost like a mini browser if you will.
