I cant figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

What is the difference between SendKeys.SendWait and SendKeys.Send?Send obviously will just send they key immediately, but does SendWait actually wait for the message to be processed or does it also send it immediately?The function's name itself is just confusing. Which one should I use if I want to send keystrokes to a 3rd party app immediately, or is there no difference? To me, a few milliseconds is a big difference.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click CheckBox1.Checked = True While CheckBox1.Checked = True SendKeys("{END}") End While End Sub
That is the code, the error is "SendKeys is a type and cannot be used as an expression."
I'm looking for the underlying Win32 API call that the DotNET Framework invokes on a SendKeys.Send or .SendWait call, or a Win32 API Equivalent to SendKeys. I've already experimented with SetKeyboardState which seems like the way to go, except that it does not raise any kind of keyboard event that causes the set keystates to register with an active application or the OS (at least not until another key is pressed; for example I can meddle with the keyboardstate before events process on a natural keystroke, but I can't invoke a keystroke programmatically).
I have a VB.Net 2.0 application, on my form I am using a Component ONE PDF reader control.I am trying to send to this control a F4 keystoke to close the navigation panel when it opens the PDF file. It is not working or not accepting the sendkey.I put focus on the control first. Code below:
Me.PDF1.Focus()
Me.PDF1.Select()
My.Computer.Keyboard.SendKeys("{F4}", True)
I have tried different variations of the Sendkeys with no success.
First let me say that I am not sure whether or not this should go in this section or the API section, and if it needs to be moved I apologize. My issue is fairly straight forward, but for some reason I cannot get it to work.
I am trying to send a command to a command line and then submit the command. I have been trying without success to get this to work in v2008 Express and v2010 Express, Here is the code I am trying to us:
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" ( _ ByVal lpClassName As String, _ ByVal lpWindowName As String _
I'm confused on when I should use the Randomize() function.It's my understanding that will give a new seed to the random based on the system clock, so should I therefore call it each time before generating a random number?I seem to recall reading once that it should only be used one time (like in the form load event), thus my confusion.
Public players As List(Of Player) = New List(Of Player)
How can I randomize the list? These are names of players in a tournament. I want to randomize the list so that they are not sitting sequentially at the table(s)
I have previously been told that I should always use Randomize() before I use Rnd() in a vb.net application, yet it always seems to work fine without it. What does adding Randomize() do for me in this case? It doesnt appear to affect my application in the least.
how do i randomize the operator?? i mean i wan the operator occur to be in random .i have to rush out my miniproject on next wednesday so i do ask the problem i meet here
Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.
i.e. Table Data ID | Name 4345 Mike 3456 Lee 4567 John
There will be many more names but for this example you could use 3 or 4 etc..
for example, string="trujade". how would i go about randomizing the letters in the string to look like the matrix code? change each letter in the string "trujade", randomly to a different alphabet letter. [URL]
I am making a random name generator. what I got is a large list of first names in listbox1 and a large list of last names in listbox2. when I hit a button, I am randomly pulling a name from both listboxes and putting them into 2 textboxes. for some reason they arent always random. I would say out of 50 names I will get 2 or 3 sets that are identical. why??keep in mind I probably have 400 first names and 200 last names. I should never get a duplicate! here is my
'randomize first names Dim rnd As New Random() Dim randomnumber As Integer = rnd.Next(1, ListBox1.Items.Count)
Can someone tell me how to shuffle / randomize a stringi got a string like: 0123456789name0123456789and i want it to become a random like: 343n3287a4738m2039e7834
I want to be able to randomize what image the picture box displays, and I want to pick it from an Image list with the collection that I want to use. I'm trying to use a custom function so that it can be repeated.
I've seen a few other people ask this question and have tried the responses that they have had with no luck.
I am trying to use the randomize command to generate a truly random number. What I am doing is reading an access table to get the number of records, then seed the randomize statement with that number of records with the top range for a random number. I then use the number to select the record I want from that table via it's ID number. My code for doing that is working great.... except that it is always calling on the same record each time through the loop. Here is the code.
im helping a school run a Spelling Bee aimed at children in year 7. And to make it fair and unbiased i need an application that can choose randomise a word from the list box then transfer the string to the text box.So basically something that can pick a random string from the listbox and show it in the textbox1.text property.
