I work with a developer that loves to put #region #endregion is his methods, and I hate it.It makes the method so hard to read. I have looked for best practices on how to properly using the #regions but I have not found anything
View 1 RepliesI know that there is no DESIGN, DESIGN_MODE, DESIGN_TIME, etc preprocessor directive value. However, I need something that can do the trick. I can't use a normal If statement, because in my case I need to change the inherited class so that the control renders properly at design time. If not, I'll receive an exception due to the fact that the inherited class is an abstract class.Here's what I'm looking to accomplish:
Partial Class MyCustomControl
#If DesignMode Then
Inherits UserControl
#Else
Inherits WidgetControl
#End If
To refresh or invalidate only a region of the form.sometimes I will need refresh all the form, but in some situations only specific regions of the form..I saw some samples on the Microsft site, but I don't understood.I use VB .net 2008
View 3 RepliesIs there a simplistic reference for all preprocessor directives?
View 3 RepliesI have seen in Debugging .net 2.0 Applications the following code [code] Is there any reason to use the #if directive? I mean, from what I understand the method will only be called if the DEBUG is defined, so I don't see a point in having the #if in the method body.

View 1 RepliesI have a multilingual company website (Visual Studio / VB / ASP.NET 4.0), and when, on the homepage, you click a flag, the text changes to that language and stays with you the entire session, after I made a class, BasePage.vb. Everything works great, but the URL never changes .... clients.aspx remains clients.aspx although the text DOES switch to Dutch.
It's been recommended by @Aritstos to make it so it looks like clients.aspx?lang=nl as opposed to just clients.aspx in another language.
Currently, my asp homepage hyperlinks that work look like this:

View 3 RepliesI have a custom-shaped form created by setting the Region to an image. I want to be able to highlight the edge of the form when it has focus. To do this I believe I need to get the outline of the form and convert it to a path so I can draw a two-pixel highlightaround the edge of the form.

View 2 RepliesFollowing my test project for making a map editor, I finally got the tile selection part covered.The application can already tell which tile(s) is selected.
So now we will work on "click the map and the tiles will be drawn" part.
When the user clicks the map, I need to "copy" a selected tiles in the tile selector, and "paste" them on the map. The process is a bit longer actually.Or is there a way to directly copy the selected tiles to the map image?

(1) Is this the correct approach?
(2) If so, how do I get the outline of the region so I can call DrawPath?
how can i get the points which make a polygon from a region which was derived from the polygon's points?
View 2 Repliesi have an image which has 2 colors, black and white.
i wish to get a region object that has all the white areas 'selected'
the shape is not just a polygon, its fairly shapeless
is this the best approach: create a region that is the size of the image and run a loop checking each individual pixel to see if its black, if it is then exclude it from the region. (i've got a feeling this will take very long to load)

View 6 RepliesImagine you want to draw a regular shape such as a triangle, rectangle ... all the way up to say a 10 sided figure ( a decagon ) or more. I know that when we try lots of sides it looks closer and closer to a circle or an ellipse. The problem I am thinking of is placing smaller circles ( or ellipses ) at the correct positions near the points of that shape as shown for a triangle below.Here comes the question(s) How could we: a) Correctly place the circles ( or ellipses ) at the points so that the sides are at a tangent to them andb) Can we combine the REGIONs of these to produce a figure with rounded points so the light blue bits get excluded? I guess that to produce a method to deal with all the mathematics involved would be quite a complex task.Has anyway previously tackled doing this or know of any .Net tools I could use for this problem?

View 6 RepliesI have a Rectangle (the class) that I'm using to define a region on a form and when the mouse enters that region it shows 2 buttons (which are on the form and within the bounds of the rectangle) and I would like the buttons to remain visible when the mouse is over either of the 2 buttons then when the mouse leaves the region or leaves the form they are set to invisible again. Here's the code I have so far:
[code]....
The problem is when the mouse enters the bounds of the button, the form's MouseLeave event fires and thus my buttons are hidden which means the user can't click either of them either.
I don't know if this is possible, but I want my form to be 'window-blocking', just like the taskbar, when a window is maximized, it won't overlap the form.

I have set a custom format for DTP control to dd/MM/yy. lets consider a real time scenerio. I have a form to enter Invoices for that i have following controls on my form 1] DateTimePicker, 2] CustomerName ComboBox, 3] Quantity, 4] Amount o.k. the Custom Format for DTP is set to 'dd/MM/yy'. When i first add entry i set the focus to DTP Control After changing date user moves focus to ComboBox then Quantity then Amount & Finally Clicks Save Button. And again hits Add Button and the cycle continues.
Now when user changes 'month'in DTP & go ahead and save the entry when he add another new entry the focus is on DTP however in the month region of DTP where it is expected in 'Date' region of DTP b'cas it is not likely that user will change month every time but he may change Date every time. This enforces user to mannualy select the desired region (either by Left Arrow Key or by Clicking Mouse button in the desired region). So after receiving focus i want the cursor tobe in the 'Date' region of DTP. Kindly help me writting correct statement to set focus to the control in the desired region (section) in DTP control.
how can i design a region in vb.net form(windows application), such that when i click any point inside a region a new page opens. my problem is that the region which i want to define through it is very complex. its a combination of a rectangle and another shape.
