This is a contradiction. WinForms is .NET. What language is your Win32 app then ?

If you're going to send it to an app running on the client, ActiveX is your best bet, yes.

hi,
I'm trying to use a regular expression to find all data following two blank lines.
this means there should be two newline formatters preceeding all data I want to find. therefore I've been trying something like:

(?<=\n\n).*

somehow I need to check the lines are indeed blank with only newline formatters and then return the text following the two new lines.
no luck though. any ideas?
thanks,
Stephen

GraphicsPath remove or alter line

Hey.

I've been trying to get this to work but with no avail. I'm trying to modify a GraphicsPath to remove a line or move it so it matches the situation i'm using.

I'm using it as part of a new Rendering mode (for the ToolStripManager.Renderer), and i've got a code that creates a path (and adds curves to the corners if I want it to).

My code gets the GraphicsPath of the AffectedArea of a MenuStrip dropdown (or ToolStripDropDownButton). I want the code to remove or alter the line to leave a space for the ConnectedArea section.

Here's a picture of the area, I mean, that I want to be able to remove (opens in new window)

The black border is the GraphicsPath lines that the code retrieves. The red part is the part of the line I want to remove.

Here's a sample of the code inside OnRenderToolStripBorder(ToolStripRenderEventArgs e)

if (e.ToolStrip is ContextMenuStrip || e.ToolStrip is ToolStripDropDownMenu)
{
	Rectangle Area = new Rectangle(0, 0, e.AffectedBounds.Width - 1, e.AffectedBounds.Height - 1);

	e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;

	using (GraphicsPath Path = CreateDrawingPath(Area, 0))
	{
		e.Graphics.DrawPath(Pens.Black, Path);
	}
}

I've tried using:

Path.PathPoints[0] = new PointF(e.ConnectedArea.Width, 0);

To try and change the first point of the GraphicsPath to start from the X axis of the width of the ConnectedArea (the GraphicsPath goes "Left-top" -> "Right-top", "Right-top" -> "Right-bottom" etc).

But it doesn't work. Does anyone have an idea how I might be able to move the first point to where the ConnectedArea Width ends?

Thanks in advance Smile | :)

Converting a project to .Net 3

Hi,
I have an application basically written in VS 2003, then I upgraded to 2005, now I'm running 2008 and I cant use any of the .Net 3 components so please tell me how to upgrade my app to be .Net 3 compatible

Thank you guys!

I don't see why you can't, there's no such thing as a .NET 2.5 project, your project is .NET 3.5 ( not 3.0 ) or it's not.

Muammar©15-Jun-08 9:37

Hi Christian,
It's good to see you Smile | :)

, I always get optimistic when the answer is from you Wink | ;)

You see, I had to use the element host thing to include some wpf controls but i just cant reference any of the .net 3 dlls when it's not the case when i create a new app in .net 3/3.5

i'm sure i just need to find a way to convert my whole app to support .net 3/3.5 but i dont know how to do it, there should be some tool somewhere withing the ide i suppose

It seems probable to me that your project did not include references to the .NET 3 dlls, and you just need to add those references.

I thought so too at first but it's not possible when the project is not based on .Net 3 framework from the moment it is created!

You just cant include any dll with the version 3.x.x as it will be disabled!
Please try now to see what I mean, I'm sure you will be surprised as I am now Smile | :)

Create a new solution based on a version less than 3 and try to reference anything from .Net 3.

Oh - there's a setting in 2008 that sets what framework you're building against, it DOES support 2.0. Perhaps the conversion is set to that by default, and you need to change that in the project settings ?

Ok sorry

I got it

total minutes difference

I am developing an internet cafe software and i want to know how can i get the total minutes from datetime1 to datetime2

for example:

14 Jun 2008 19:20:15 to 15 Jun 2008 21:53:45

User 665815-Jun-08 8:35

User 6658

15-Jun-08 8:35

This will work:

TimeSpan span = t2 - t1;
double minutes = span.TotalMinutes;

round the fils

Jassim Rahma15-Jun-08 8:18

Jassim Rahma

15-Jun-08 8:18

in my country, our currency is (Dinar) and we have small units called fils (three decimals)

we have coins 50fils and 100fils

1 Dinar (BD) is 1,000 fils (10 coins)

I want to round to the nearest 50 or 100 fils based on user's setting.. for example:

if the amount is 0.513 and round is 50 then it will be 0.550 but if round to 100 it will be 0.600

if the amount is 1.148 and round is 50 then it will be 1.150 but if round to 100 it will be 1.200

how can i do that?

size of an object of a class

15-Jun-08 8:49

This is not rounding; you're taking the ceiling to 0.05 or 0.1 (in case it's not an integer amount of money)
A hint,
0.513 ceiling to 0.05 = 0.5 + 0.05 = 0.55
1.148 ceiling to 0.1 = 1.1 + 0.1 = 1.2

But you want 1.000 to return 1.000 not 1.05 or 1.1 so you'll take that into account. And use decimal not float or double.

there is a class, say

class a
{
int i,j,k;
}

then, another class is derived as,

class b:a
{
int a,b,c;
}

now how many locations in the memory the object of class b will occupy, i mean wat will be the size of object of class b.
3 or 6 ???
i have tried to use sizeof operator.
But the compiler is giving error !

Re: size of an object of a class

15-Jun-08 9:22

First, this code doesn't compile because you have a data member with the same name of the class "b"

Second, I think you want to know how many data members are there in the class B. There are 6 data members i, j, k, a, b and c. But you can only access a, b and c from the class B because i, j and k are private members of the class "a".

If you really want to know the size in bytes,
