Multi Key Hotkeys In VB 2010?
Feb 24, 2012
I've written a simple WAV player in VB 2010 - a Windows Form App with no menus. I'm trying to create a hotkey, like CTRL-D that would make a text box visible. Typing the correct password in the box will expand the form and show some Administrative functions. I'm having issues creating the hotkey with more than one key.I've got the following code, but it does not work. I do have KeyPreview set to True.
Private Sub _KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
If e.KeyCode = Keys.Control And e.KeyCode = Keys.D Then
txtPWD.Visible = True
I've also tried
If e.Keycode = Keys.ControlKey & e.KeyCode = Keys.D
and many other variations including changing to ALT and SHIFT but nothing seems to work. If I remove one of the Keys, it works just fine.

I'm working on a project that contains hotkeys, but I don't wish to have global hotkeys. At the moment, I'm using KeyDown and e.KeyCode for hotkeys. I've created test projects where these worked perfectly fine, but on my main project, they don't register.

I've been raking my brain for quite some time on this. Is there any way with VB.NET that I can use multiple IP's in one instance of a program? For example, I want to be able to navigate to a web page 10 times at once, with each one using a different IP. I want them to be parallel (multi-threaded) rather than going sequentially. Going sequentially, I could just do the action, change the IP, do the action, change the IP.

How do i go about multi-threading that, it's just an example project, so i can try and learn from it. As i'm having a hard time understanding JMC's tutorial as it doesn't directly relate to what i'm trying to do [code]When you hit 'Start', the start button is disabled and the Label1 then changes to "Downloading".The data is then downloaded and put into the Textbox1.Label then reads "Complete" Start button is enabled.

I have a button and when it's clicked a HTTP request is sent out to a website to do a few things, but because its got to load the external resources it makes the interface frozen. I've moved the HTTP onto another thread using the follow
VB.NET Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Thread1 As New System.Threading.Thread(AddressOf check_accounts)
[Code]...
When i want to update a label that is on my main form (from the check_accounts sub). I know that isn't the right way, but i have no idea what the right way is. All the documentation i can find is very (excuse me for this) nerdy and really doesn't offer much insight on how to incorporate it into a project.
I want to be able to have a numericupdown box that can let the user change the amount of threads they want to use. I assume more threads allow the http requests to be done faster and at the same time?Also if i wanted to pause the HTTP requests, would the best method to use be pausing the thread?

In my football sim I am trying to save all the info from a game. There are two defined dimensions to this array. The first is the number of weeks(17 always) and then the number of games per week (Number of teams /2). The plays themselves are unknown in quantity so I decided to use List of to store them. With this type of multi-dimensional array that is also a List of I am having trouble with the Get and Set properties. I have a member variable declared as:

I am a Network Administrator in the Army so programming is not my strong area. I have been messing with Batch files and WMI, just recently i started VB Scripts (VERY BASIC) like adding an input box to set computer name, scan network for computer name on domain, return wmi info for that remote computer etc... I know there are programs out there that can do all of this, however the Army will only allow certain approved programs to be installed on government workstations, i have been using .Bat files to gather info which is fine, however it is very time consuming when you have entire subnets with computers, networked printers, etc to place into a spreadhseet for higher headquarters tracking not to mention the over 20 columns of required data to track for each computer. I have VB 2010 Express, working on a Windows Form Application Project. Goal is to interface my VB Script (written with notepad) with a GUI that will generate an internal spreadsheet on the form window in a datagridview. So far i have the basic window and i have my gridview with my column headers set. How do i get the data into the columns and rows accordingly.
Application Basic: Execute Program, in main window select button (Scan IP Range) <--- I want this to open an input box for the beginning subnet, input base address to start scan from, next input box for end range, then msgbox for start scan. i want the results of the scan to autofill the datagridview and add new row for each IP address that had a ping reply, returning valid data from WMI results as it receives the data. What would be the best method to achieve my goal. i am not asking you to write the program, i have been looking and studying MULTIPLE sites, think i just need another set of eyes on this to unlock the knowledge i have locked away, if ya know what i mean. Also, if you don't mind let me know what you think of this app im trying to turn out... Super Thanks for your help.This is the Base Batch File running. It calls an external VB Script written in notepad. (I want this implemented into the app form so there is no console window.)This is the inputbox from external VB Script that is called.This the result of the external VB Script (the info i want to put in the datagridview of the app.)I also, for some reason can't get scroll bars to show in the app when i hit F5, theres about 15 columns passed the MAC column...?

I'm having some issues with parsing a lot of information into controls using winforms. I've tried adding threads/backgroundworkers, but they don't seem to work properly. To avoid the cross-thread exception, I had to add an invocation checker:If Me.InvokeRequired Then Me.Invoke(New MethodInvoker(AddressOf ParseSub()))This just freezes the form as it would without threading, but without the invoke checker I get cross thread exceptions because information from one thread is trying to be sent to another.

I'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

I have a need to build an app that will access about 10 websites and pass data to them, etc.I've read about something called multi-threading when searching Google. I've also seen people say that they use multiple browsers.Which route is better to use? I figure if you have to do some sort of multi-threading that you would access a single browser?

i have having a annoying problem to do with loops.
[Code]...
When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.

I think I need a two dimensional byte array I currently have something like this:
Dim MbyteData(196608) As Byte
' Open the file that is to be loaded into a byte array
Dim oFile As System.IO.FileInfo
oFile = New System.IO.FileInfo(sFilePath)
[code]....
I now need to load several files at once (say four) so I need four arrays of 196608 bytes and I want to reference them by a number - 0 to 3, assuming the array is zero based. If I use Dim MbyteData(196608, 3) as byte or Dim MbyteData(3, 196608) as byte the syntax seems to be correct but I hit an error ("Number of indices is less than the number of dimensions of the indexed array") when I try to add the extra dimension to the stream read with something like oFileStream.Read(MbyteData(index), 0, MiByteCount).

I've got a multi-threaded app - that is using a global COLLECTION of objects.I'm starting to think that objects - when copied to objects - are really just reference pointers to the "single object" in memory - as they would be in JAVASCRIPT (too many languages At any rate - this code - when taking the object from the collection to work with is it making a new object to play with or is it working the single object that actually resides in the collection?

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have

How can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.
