I have a form that allows me to drag and drop pictures but I want it to check if the object is in the correct location
*curpic = the current picture that has been selected
If curpic.location.X > bx1.Location.X And curpic.location.Y > bx1.Location.Y Then
If curpic.location.X < bx1.Location.X + bx1.Width And curpic.location.Y < bx1.Location.Y +

how to check if a picturebox is inside a form?
View 7 RepliesI designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?
View 2 RepliesI'm writing a .NET program for an engineering company. Their specification is to find the number of holes (either of same or different radius) on a rectangular plate and then to find the area of the rectangle and also area of the circle inside that rectangle. It's not essential that the circle touches the rectangle.
View 1 RepliesHow can I check if a ListView has items that are not in its visible area?
View 5 RepliesI want to create a dial which is basically a circle that I can drag around in a circular motion. Ive looked at using the code in an earlier post which allows you to drag items around a screen but I cant figure out how to confine the movement so it only allows the user to drag this circle around in a circular motion. Any coordinate altering I do just looks snappy.
View 6 RepliesI'm working on a Vb.net project. I have a form with a RichTextBox or a simple TextBox control. It contains hundreds of text lines, so the control has to be scrolled.
I want to send to a printer only the lines that are currently seen on the control window.
That is, I want to convert what I see into an Image and then draw that image thru e.Graphics.DrawImage.
As you can see, it could also be the case of a ListBox, a TreeView or any other scrollable control.
How can I grab that rectangle area and then convert it into an Image? The rest I already know how to do it.
I guess thats what I need to do, Im trying to allow the user to right click on the top of my form, and my custom Context Menu Strip is displayed, not windows context menu strip. I guess somehow i would need to get the size and draw a rectangle on the non client area and see if the user has right clicked in that rectangle? if so how would I get the area of the non client area?
View 7 RepliesI'm trying to extend my new WPF Touch Screen Keyboard (DLL) Library, to allow the user to get events from the Touch Screen Object. I'd like to be able to tell the Programmer what Object made the call (or executed the subroutine) that raised the event. Not dissimilar to the Sender as Object event parameters one gets when working with a System Object. Which begs the question, How do I get that information, if I don't ask for it?Is there a way to get this information from some call made in the subroutine about to raise the event?

So I'm trying to take a screen capture of the windows form and display only a certain specified area of that screen capture in a picturebox on a different form. Kind of like this. First, take the screen capture of the form: Then get a specified area of that form through x,y coordinates or something and display it on a picturebox on a separate form.
Is this possible?

I'm trying to XML-serialize a class the properties of which I use to format a document.Basically, it is a class for the document's header and another class for its rows. url...In this class diagram, the class I want to serialize is ExcelPrintCorte that inherits its methods from ExcelCabec and has a private member ExcelPrintDocumento (and a public method to get it).My purpose is to XML-serialize ExcelPrintCorte and save the inherited properties' values and also the properties' values of ExcelPrintDocumento.

I use Visual Basic 2010 Express. I want to create a WinForm app in which there are several buttons "table1", "table2"... Each button must display the corresponding table of a database in a specified region of the same form.

View 3 Repliesif any one knows of a way to determine if a control is currently in the viewable area of the parent form. In example...if I have a form where all controls are visible when the form is maximized, how would I go about determining which controls are no longer visible to the user after they change the window state or form size. To be clear I am not talking about the visible property of a control but rather if the control is actually on screen for the user to see when they do something like resize the main form for instance.

My VB.NET app supports several kinds of MDI child forms. Some kinds, but not others, are 'troublesome' -- they cause the focus mechanism to become weird. Once a 'troublesome' child form has been opened, NONE of the MDI child forms will become activated unless I click on either the title bar or the border. Clicking in the client area does not activate the child form -- its title bar remains gray, and it does not receive Activate or GotFocus events. Strangely, however, the clicked-on form actually DOES receive the focus, because its controls receive mouse and key events. Only the Z-Order and the highlighting do not change.
Once this problem develops, it persists even after the 'troublesome' form is closed, and it affects child forms which are opened afterward. However, if ALL of the child forms are closed, the problem clears up, and new child forms behave normally -- until the next 'troublesome' form appears.
I have no idea why one kind of child form is troublesome, and others are not.
