So basically im around 2 months into building a text based rpg game in vb 2010 which is coming along lovely. there are unique charachter creations, bans, loans, monsters to fight, levels, skill points, spells, inn's, etc etc... you get the idea. so now its time to move on to one of the largest problems of all. an inventory :O now, i have a db with the correct information in, i have even sorted all the code for the program to read the db with the correct items and its all working fine. but now i would like to have a more gui system. meaning:a grid based box where pictures of each Item_ID are displayed so you can see what items are in your inventory at any time. now i can sort this out myself with a case select and just load all the images into the local resource and pull itempictue1 when id = 1 itempicture2 when id=2 etc etc you get the idea. what i was woundering is...
could i build a drag and drop system where the player can move the items inside the inventory fairly easily? i have done some research into this but as vb isnt much of a gaming language i've run into a fair few dead ends. Not sure if i have come across right, but in essence, if you have a grid, 4x4 and item 1 is in grid space 1 and item 2 is in grid space 2.. to swap them around with the mouse.Please, dont shout if im asking too much :L nobody likes haters. any help is much appreciated and if you dont think vb can do this then please tell me and i will consider all alternate possibilities unless you have a better idea?

How do you add an item to the system context menu? I would like to let my users be able to right click anywhere and launch this program. I cannot seem to find it documented anywhere either.

I am looking to create a menu system in vb 2010 windows app. See attached file to give you an idea of what I want to achieve. I could do it by creating 4 buttons and have 4 panels. when button one is pressed make panel one visible and hide other 3 panels, etc This just seems messy. Will any of the built in VB menu components do this?

I has been looking for the codes which it avoid the system menu to be showing on title bar when you click on your right mouse button. The only one I found is removemenu method. I don't want to use removemenu as it would disable the title bar close button. I only needs the code to avoid me to click the right mouse button on the title bar so I still has no luck.

I have written a VB.Net Windows Application using VS2003.Net under the 1.1.4322 framework. This application loads a lot of data on startup (about 4MB, taking about 30 seconds) and that data needs to be readily available to the user, so I wrote it to sit in the system tray, using the NotifyIcon and ContextMenu objects.Everything is working fine, even the menu (I have simple options like 'Update' to update the datasets, 'Show' to show the form, 'Hide' to hide the form, and 'Close' to actually close the application).However, when the user attempts to do a Windows 'Log Off', 'Restart', or 'Shutdown', the system refuses.After shutting down every application on the users' computers EXCEPT for my application, the system still refuses to perform the LogOff, Restart, or Shutdown event.In fact, the application I wrote does not even perform it's 'Dispose' method.[code]Therefore, I am convinced that it is my application interrupting the system's process somehow.I have written other Windows Applications WITHOUT the context menu / notify icon objects (apps that don't sit in the system tray) and this problem does not occur.I have also written other applications that DO sit in the system tray, and the same problem occurrs.To summarize this problem: I believe there is something wrong with the way my application is responding to the System events 'Log Off', 'Shutdown', and 'Restart'.This is occurring on Windows XP SP2 computers (has not been tested elsewhere).Could someone explain to me why this happens?? Is there some workaround or some known bug in .Net that causes System Tray applications to interact differently with Windows system events than expected??

my test:
Public Class Form1

and i get an error:
PInvokeStackImbalance was detected
Message: A call to PInvoke function 'WindowsApplication1!WindowsApplication1.Form1::GetSystemMenu' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature.

i want to be able to open IE/FireFox/Google and the like, and when i right click in a text box on a webpage i can click my email so that it places the email address straight into the box instead of typing it in. in other words i want to integrate a ContextMenu into the already system context menu. I think i am shooting above my belt but just need a start as to where to start. Ie: Service, Background Worker, Windows Form?

We are in the final stages of releasing a new in-house written system within our company. We have opted to create a single system/project containing multiple programs (like a mini ERP system).We are stuck on the navigation mechanism which will allow the user to load the appropriate forms. I am personally not a fan of the Tree View control because I think it is unfriendly to users. I have been looking on the web for some inspiration and I am interested in the design of the OPEN BRAVO ERP system. Before we dive in though, I wanted to get other programmers opinions. What do you find works best in VB 2008?

Simply saying I've added an Notify Icon to my project and then added context menu showing up when the left mouse button is pressed. The problem is that with the context menu some blank form is showing in the taskbar. There is no such form within the project.Does anyone know why it may be happening or how to get rid of the effect? I might add that I have other context menu attached for mouse right click button and it works fine, no blank forms and such showing on the taskbar it's just the left mouse button that works that way.Here is the code that I am using to show the menu:(the visible state to false is necessary for the other menus not to pop up with the one i want... unless anyone knows better method)
Private Sub NotifyIcon_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles NotifyIcon.Click
If e.Button = MouseButtons.Right Then

I am currently using the following to Get Path of all Open Explorer Windows:
foreach (SHDocVw.InternetExplorer j in new SHDocVw.ShellWindows()) {
if (j.Name == "Windows Explorer") {
ListView1.Items.Add(j.LocationURL);
}
}
But it doesn't return the location of special folders like Computer, Recycle Bin, Network etc. Is there a way to identify those folders so I can put the path on my own like shell:MyComputerFolder for Computer?

I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll
As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?

Here is the stack trace:
2012-03-16 19:15:09Z E System.NullReferenceException: Object reference not set to an instance of an object.
at System.Timers.Timer.set_Enabled(Boolean value)
at System.Timers.Timer.Stop()
Here's the code:
Timer declared as private member variable.
Private _myTimer As System.Timers.Timer
Initialize timer method.
[code]....
The timer has to have a value or else the Timer.Stop() call would be throwing the exception. This is a sporadic error and I'm just trying to see if anyone has experienced this before or if anyone has any ideas of what could be causing it. It is occuring in a WinForms application in the event handler for the Elapsed event of the Timer, but it is only occuring sporadically on the users computer. I haven't been able to reproduce the error myself.
