I'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:

View 10 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()

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.

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 :

10-9890-1 mfgtest1 Progamming.xml config5.conf

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 6 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI need to capture the left and right arrow keys in Form1.KeyDown event so I can use them as hot keys. Instead they seem to be assigned to tab order (move focus to previous/next control) and the KeyDown event never gets called. How can I remove the arrow keys from tab order and use them for my hot keys instead?
View 2 RepliesI tried a couple of the send keys and they will not send any keys at all. I need a true Space bar input (SendKeys does not work for me). Also, I would like this to work on 32 and 64 bit computers. Let me know if you know of any good examples. I would love to have the ability to send a string in the future, but I can add that feature myself. [code]
View 2 RepliesIn C# I can do this:new SomeObjectType("abc", 10);
In other words, I can call new without assigning the created instance to any variable. However, in VB.Net it seems I cannot do the same thing.New SomeObjectType("abc", 10) ' syntax error
Is there a way to do this in VB.Net?
I have a form that contains a lot of textboxes, I want to populate these boxes with values based on a certain criteria. Two integers are required to decide which boxes should be filled. When I added the textboxes to my form I named them with this in mind so my boxes are named textBox11, textBox46 etc where the number part of the name will represent the two integers which decide the box (none are greater than 9). So I basically need to compare the textbox I create in my code to the textboxes on my form to determine the ones to add text to. Here is a shortened version of what I am trying to achieve.
