im trying to make a two player game in vb 2008, it involves to ships either side of the screen shooting at each other.
A problem that ive found is that my code or vb wont recognize two keyboard inputs at the same time.
Private Sub Form3_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode

I've encountered another minor problem with using vs 2010...how do you assign shortcut keys? I've read you just click in the shortcut keys option then press the buttons you want to be your shortcuts- this however just acts like I'm pressing the shortcut keys for vs. for instance alt x, which I want to be exit, takes me to debug. Typing alt + x in manually gives me an error saying what I've put in is invalid.
View 8 RepliesI am trying to list all printers (PrintersConnections) under all users (HKEY_USERS)
problem is I dont know the user name keys in advance and need to exclude .DEFAULT and *_CLASSES so first I need to list all key names (%usernamekey%) directly under HKEY_USERS then for all keys that lists lsit all keys under HKEY_USERS\%usernamekey%PrintersConnections
Here is the code I have so far but I get errors about object variable not set, I suspect because of the way I doing the for each and listing the key names and then doing it again
Code:
Private Sub DetectPrntrs()

View 2 RepliesI'm creating a project that involves hot keys, but it requires multiple hot keys instead of assigning one. I'm going to make it so if a user presses for example CTRL + T on they keyboard while a textbox is selected, it'll show CTRL+T in the textbox and assign the key to do something. How do I do these though? Here's the code I've used for single hot keys:

in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

I can detect single key downs with this code, however once I push multiple keys vb.net ignores previous key and only focuses on the other key. Can someone help me figure out how to detect multiple keydowns at the same time?Private Sub frmMain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown

I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I am designing a test launch tool that I want the user to be able to select a product type from a list and then choose a station type from another list. Depending on what they choose will determine what is run (what is passed out).
The data will look like the following :
Product Station Test to load Config file to use
10-9890-1 mfgtest1 Progamming.xml config5.conf
10-9890-1 mfgtest2 Configuration.xml config92.conf

Now as you can see it is sending the textbox1 text and then pressing enter then sending textbox2 text! Theres quite a few problems in that but before i discuss note: This code is in a Timer. Problem #1: It does not send the keys fully correct all the time because its trying to send them all at once! So i want it to send them 1 letter after the other with 200 ms sleep in them! Problem #2: The sleep is not working: The reason i know is because even after it did the first textbox1 text it didnt wait that 2000 ms!
just wondering how i could give my auto typer hot keys, for example they press f1 to start the typer f2 to stop it.

I am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?
I am using VB.net 2008 and Windows XP.
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 8 RepliesHow can i code my application so that it can handle two sets of key events at the same time? For example, if I was making a game where one player used the WASD, and the other the arrow keys for moving, how can i make it so that both can move at the same time? The code I used only allows one to move at a time.. (key press event, If e.KeyData = Windows.Forms.Keys.down then.... etc)
View 1 RepliesI've got an application in VB 2008 with, 1 richtextbox, 1 toolstrip and 1 menustrip. My toolstrip has many buttons, 5 of these being a: bold button, italic button, underline button, strikeout button and a regular button. However it is only possible to have ONE fontstyle at a time. If you want Bold AND Italic, it is impossible.

Make it so that the user can have more than one fontstyle at a time. Make it so that the user can click the button again to remove that fontstyle instead of clicking the "regular button".

I will use only password(which will be chosen by the user from a combobox(combobox1.text)) because the username is harcoded. This is what so far ive come up with but it always gives me the result of the first line(or referer) from richtextbox1. I think there might be a problem with my "FOR" code.

View 2 RepliesIs there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?
