im trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)

Imports System.Runtime.InteropServices[code].....

View 1 RepliesThe purpose of my application is to keep track of users waiting to use another application that may only be accessed by one user at a time.My vb.net application adds the persons name to the end of a text file, removes names when a person either gets to the front of the line or exits by closing my app.It regularly checks the list, and when the user gets to the front of the list, it notifies him and loads that other program.My problem is, I don't want the user to have to sit staring at my app until they get to the front of the line.I want the app to cause the computer to emit a regular, slightly annoying beep,even if the user has minimized my app or pulled up Microsoft Word on top of it, and continue to beep repeatedly until the user switches back to my app and presses a key or clicks the mouse.
View 4 RepliesI am building a application in VB 2010 Express, that tracks sales leads, I have everything working except 1 last item. I want the users to be able to select a different background image to match their industry. I have all the images embedded, but can't figure out how to allow the user to select.
Preference is to have a separate form for the user to cheese on launch, but I am OK with it just being a dropdown in the lower left corner of the app.
Using arrow keys to move a shape also changes the value of trackbars elsewhere in the program?

I am attempting to write a simple 11ball style game. It requires images of poolballs overlapping each other. Since the balls will need some internal intelligence I was hoping to create them as usercontrols.I am having trouble gettiing the control's background to be transparent.Setting the background color to (Web) transparent only makes the background clone the form background color.

View 4 RepliesI'm working on a CNC control program, based on a DLL that someone else wrote. No problems with that sofar, as i get good support from the writer.
The problem i do have to tackle is the following: I want to acces all the functions by means of softkeys ( the F-Keys at the top of our keyboards ) when the program starts it shows the Main menu softkeys ( F1-F12), and each F-key has a function assigned to it, some will make the machine move, others will show another menu, or a fileopen/save dialog, depending on the chosen keys.
All works fine and handy-dandy, except for the F10 key, it seems to be "Sticky", when i press it, the program will not react to any other key, only the F10 key can get it back in "normal state" accepting every key with a function assigned..
How to "unstick" the F10 after pressing it?.. because pressing F10 now, means no other key will do anything, and that may become dangerous, when the machine is moving and it must be stopped..
How could I loop through a list of the keys that are available in the 'Keys' enumeration? It seems like it should be something easy to do, but I'm not having any luck finding a collection that I can loop through.

View 3 Repliesis it possible to call another program in the background? I'n doing a project that uses .net to control a camera. the camera is nikon, which has a sdk. unfortunately, the sdk is an unmanaged dll, from the research I did, people complained that it is difficult to use it in .net. actually, no1 has example. but the sdk has sample in vc++. so, I'm thinking maybe can build the control program by vc++, then use vb.net or c# to it and run it in the background. so, I do not have to mess the dll to .net.
is this a good choice? or, not really? how to do it? if I use a console program, how to avoid popping up the cmd window?
I'm trying to change the background color of a node that is being hovered over while the user is dragging items from a list box.I've gotten both functions to work separately, but while the user is dragging, the NodeMouseHover event does not fire. Is there a way to do both?
vb Private Sub trvNavigation_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles trvNavigation.DragEnter
If Me.CanMove(e) Then
e.Effect = DragDropEffects.Copy
[Code]...
Note: CanMove() is a function I made that verifies the dragged data. Nothing else. And I will change "Color.Blue" to a system color later.
