View 3 RepliesForms :: Changing The Backcolor Of A Control When It Has Focus And Lost Focus?
Feb 16, 2011Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

View 1 RepliesForms :: Form Losing Focus - Keeps Loosing Focus ?
Nov 26, 2009I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

View 3 RepliesLost Focus Event, What Control Is Getting Focus?
Mar 21, 2012I have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

View 2 RepliesCopy An Image's Region To Another?
Jan 25, 2011Following 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?

View 2 RepliesGetting A Region Object From An Image?
Feb 2, 2010i 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 RepliesA Complex Question Regarding The REGION Of A CONTROL.?
Feb 26, 2012Imagine 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?

Here's the code I have so far:

Date Time Picker Region Selection
Jul 7, 2010I 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.

Problem is compiler does this odd error and highlights each time '#' sign appears which is needed to define colors in CSS. I did try to change '#' to '/pound/' and then string.Replace() on RETURN but no luck. I'm more into C# so there i can escape special characters by using '' before them but something f$#$ed up there... Once i remove '#' all back to normal and compiles well.
