Today I started a little sub that would let me move a control around the form using ssigned keys but would stop at the edges of the form. I can get it to move around alright but I can't get it to stop at the edges of the form.

[url] How is this done? Is it a control of that form? Or is it a splashscreen or something like that?. I've tried by doing that with another form instead, but the first form will get unfocused, and i want the main form to be always focused.
View 6 RepliesI am making a user control named MultiSelect, which consists of a textbox. In this textbox I put substring. I want the user control to show a treeview outside the MultiSelect boundaries where items matching the substring will be shown.
For me its no problem to make a treeview inside the MultiSelect boundaries but I need to save space on the original form where a MultiSelect control will appear, so I need to do it like the treeview will appear and after I choose items, it will disappear
say your silverlight area on a webpage is 200px by 200px.you open a child window, is there a way to make it moveable outside the 200x200 silverlight area?or say you drop down a combo box, let the drop down go out side of the 200x200 aea?
View 1 Repliesi am trying to make a game in vb.net and so far have managed to create a sprite which is animated on key event. the only problem is it able to walk off the form out of site. i want to be able to create some sort of boundary so that when sprite position equals greater or smaller then the form width it can no longer walk in that direction, the same goes for the hight. i have tryed this myself like this

I'm using KeyDown to get the picturebox to move around, but I don't know how to keep the boat within the boundaries of the form. So if it hits the side of the form, I want it to just stop.
What control/procedure should I use to do this?
So I've created a series of objects that interact with a piece of hardware over a serial port. There is a thread running monitoring the serial port, and if the state of the hardware changes it updates properties in my objects. I'm using observable collections, and INotifyPropertyChanged.
I've built a UI in WPF and it works great, showing me real time updating when the hardware changes and allows me to send changes to the hardware as well by changing these properties using bindings.
What I'm hoping is that I can run the UI on a different machine than what the hardware is hooked up to without a lot of wiring up of events. Possibly even allow multiple UI's to connect to the same service and interact with this hardware.
So far I understand I'm going to need to create a WCF service. I'm trying to figure out if I'll be able to pass a reference to an object created at the service to the client leaving events intact. So that the UI will really just be bound to a remote object.
Am I moving the right direction with WCF?
Also I see tons of examples for WCF in C#, are there any good practical use examples in VB that might be along the lines of what I'm trying to do?
is it possible to draw an accurate circle in vb.net with mouseDown and mouseUp boundaries? I only manage to create circle-settings with rectangular boundaries using DrawEllipse. I've tried to work around it using pythagoras but it just doesn't work and I'm pretty sure I've got my maths right...
Is it possible to define a circle with DrawEllipse(pencil,x1,y1,width,length) ?
i've drawn two boxes (one with spotcolour color of orange) in a picture box. box a stays fixed at the bottom and box b can move. i've restricted box not move outside the picbox, but it needs to change color (to red) when it touches the picbox, and i've tried can't seem to do it. boxb also can't overlap boxa.

I have a list of points X(horizontal), Y(vertical), and Z(depth). I want to be able to plot them out so they can be viewed and since it is 3d I want to be able to rotate the image as well. There would be a line connecting each point to the next, until the end of my list. If possible I would also like to be able to click on an individual point on the image and be able to tell where that point is in my list.The problem is I don't have any idea on where to start on this. I know how to create some pretty basic/genaric 2d bitmaps but 3d and some of the features are an entire different story.

View 9 RepliesI'm normally an ASP.NET developer but my latest project has me writing a console app. For this console app to function, it needs two executables, two DLLs, an XML file that should be configured with a WinForm I've developed (so another .exe), and a working folder should be created (for when my console app runs). Further, it would be nice to have it automatically set up a Scheduled Task for batch operation.How do I package the various files into a self-extracting package? I'm playing with WinZip's self-extractor creator and it's okay, but I don't see a way for it to launch further processes, such as creating a working folder for the console or launching the WinForm above.Is there a way to create an auto-extractor in VB.NET where zipped contents are part of the "payload" of the .exe? It seems to me this would give me the most flexibility, as I could write a WinForm that does everything.

Is there anyway to create a standalone executable file in VB.NET so that i have to just give the executable only which will run on any system (which has not Dot Net installed) without any setup. What I want to mean is If I copy the executable file and paste it on other pc, it should work.
View 13 RepliesI have a project on VS 2005 which was running fine with exchange 2003, now the customer migrated to 2010 and my app. is failing when tries to create mailbox. My app. is console based and its running on windows 2003 and 2.0 .net framework. Exchange 2010 is running on a W2K8 and 3.5 framework.

I want to create a simple Hello World or whatever kind of application I want but I don't want it to be a ClickOnce app and I'm using Visual Studio 2010. How would I do this. I'm interested in this because I'd like to have a custom add/remove program icon for my application and not the standard ClickOnce icon that you see. I'd also like to create a custom updater that wouldn't use ClickOnce, and I'd like to bypass all the "Are you sure you trust this publisher" messages that you get when using ClickOnce.

View 20 RepliesI have an application that tests various hardware components for notebooks. One of those components is the keyboard.I have a form that displays a keyboard. In that form's KeyPreview event, I get which key is pressed. If it's the correct key, I disable the visual UI cue and move on to the next key.I'm converting the bulk of the code into a library so that it can be used in other projects more easily. But I'm having a hard time grasping how I would create this event in my library and still allow the same functionality.
