But, if the user while drawing, enters the region 1, I want to assign a value to variable, say a=1. Correspondingly, if the user without leaving the mouse button previously enter the region 4, I want to b=1.After the user leaves the mouse button, I wanted to compare a and b. If both of them are equal, then Result=Done else not.

Another thing is this form for Daily Income. I want the form at the back (Main Form) not clickable unless I closes the Daily Income Form.

I'm currently in a programing class for vb.net. It's my first true exposure to OOP and I'm looking for some advice on areas where I could improve. I was wondering if someone would be willing to look at one of my programs that I have written and offer advice on areas where I can improve and things that I made much more complicated than they need to be. I'm not looking for a line by line critique just a general look at things to improve upon in the future.

I have some code that I've inherited, and it's not the greatest in the world, but it works, with one small exception:
This page is a directory search, it has controls identified by record ID, however there exists a situation where there can be more than one result with the same record ID, thus making .NET barf. I had originally implemented a check that just didn't put the control on the page, if it was already there, but we've been getting negative feedback.
My question is this: Is there a way to put the same control in two places at once, for instance having if a user checks one, the corresponding one checks as well? I'm not terribly well versed in how .NET behaves, but I'll try to provide as much additional context as possible, if needed.
EDIT: Here's the updated code that generates the controls by looping over a datatable of results
Dim cbxSendInfo As CheckBox
Dim strCheckboxID As String = "cbxSendInfo-" & drOrganizer("ID") & "-" & i
Debug.text = Debug.text & " Loading Checkbox (" &
[Code]....
Where drOrganizer("ID") is the record ID, and i is the result record number.
I know this is a terrible way to do this, at least from my background, but like I said, this is inherited code that's been hacked to pieces.
I need to save in my Database, records that have a big amount of lines, and like we know each text field of Access database, have just 255 caractheres to insert.
View 4 Repliesi have an Ajax ActionLink which normally just returns a PartialView (which is just a UserControl ascx file) however, my needs have changed and i want to return another PartialView (so a total of two PartialViews) that occupy different areas of my page... of course i can't call " return PartialView("UserControl.ascx") " twice in a row consecutivelly... so my question is what would be an elegant work around for this?
how can i return two PartialViews WITHOUT wrapping these two PartialViews up in a larger parent view? i hesitate to do this because both items are in a different part of the html table which would require me to include practically the entire page in the parent view due to the structure of the table, and in this case lots of html data unnecessarily would be sent to the browser at each request - defeating the purpose of an ajax call/partial update (correct me if i'm wrong).

View 1 RepliesI'm writing a small program that loads a folders contained file names into a list box, you then double click one of the file names listed and it appears within the programs text area where the user may freely edit it. I then have given the users options to export the data contained within the text box to a word template. What I'd like to do is add a button which the user can click in order to strip away all the html within the text areas content. I found a solution but for some reason I can't make it work. There are no errors displaying nor does the program crash out, it simply isn't doing what it should be doing.
The function I'm using is below:
Function stripHTML(ByVal strHTML)
'Strips the HTML tags from strHTML using split and join
'Ensure that strHTML contains something
If len(strHTML) = 0 Then
stripHTML = strHTML
[Code] .....
I've used the below snippet in an attempt to put the function to work in the text box.
Private Sub btnHTMLstrip_click()
' calls function stripHTML, applies to text box
richTxtBox.Text = stripHTML(richTxtBox.Text)
End Sub
So, its not working as it should?
To reduce the size of some images I have, I'd like to remove the white padding that some have. The idea would be that if one has large white areas on the borders, then those can be cropped to save some space.

I have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control. But instead of that approach, I'm thinking about displaying a 'clock' image and shading those areas with some color. This is similar to a Pie Chart. But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.

For my own amusement more than anything I am trying to create a program that has a world map then when you click on each country it leads to another form. At the moment I have the World Map as a background image on a forum, The only way I can think of at the moment is to have picture boxes but the countries are too packed together for this to work effectively and I believe that you can have transparent backgrounds on picture boxes.
View 3 RepliesI monitor door cameras with a third party application that gives me multiple video windows for the various video inputs in the card. I want to create an application that will overlay the video windows so that each video window becomes a button I can click on to trigger some events (lock release for example).
I've managed to get something working by using the TransparencyKey of the form set to the backcolor of my button. I though I had it done, a great transparent button in the form, and handles all my click. However, there's a little issue with portability... it won't work if I have the Windows Classic theme enabled.
One of my systems is locked down with the windows classic theme. With the Windows classic theme (whether running XP or Vista), the transparency works a little too well, the mouse clicks actually go through to the underlying window and the click event never gets triggered on my application's button.
Button1.BackColor = Color.Cyan Me.TransparencyKey = Button1.BackColor
I want a clickable area (that can handle MouseClickEvent, DoubleClickEvent, etc...) that is transparent, hence you can look through it.For example: I have Form1 with a bunch of buttons, text fields, etc. I want a clickable area that is over the whole Form1 (thus over all the buttons, etc).If you click this area, the clickEvent for this area should be could and not the eg: button underneath this area.Most importantly of all the area must be transparent, thus all the buttons, textfields, etc underneath the clickable area should be visible. Something like a panel or pictureBox that you could put over the buttons would be fine, but a if you drag a panel/pictureBox over a button, the button is invisible, and if you say send to back, the event of the button will be called and not that of the clickable area.I want the blue area (in this case a picture box) over ALL the buttons and textboxes, so that if you click this blue area a function should be called. This area should actually not be blue, but transparent/colourless, so that you can see the buttons underneath. If I say send the picturebox behind the buttons, then when I click on a button, the button's function is called and not the picture box's function as I want it.It is impossible for me to change all the event handlers of the buttons/textboxes etc, because I also use components that don't have the necessary event handlers that I want.
