Find A Character At A Current Position?
Oct 31, 2011
I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
Private Sub picBuyLetters_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picBuyLetters.Click
Dim index As Integer = txtWordinStars.Text.IndexOf("*")
[Code].....

Dim str as string = xxxxxxxxxxxxxxxxxxxx£xxx£xxxx**£**xxxxxxxxxxI want to remove £ in the bold which is always at certain position (11th for instance) from the end. The whole string is a long one, always change in size and can't be counted from the start. Can't use Replace as well, there may be same characters at other positions that I don't wish to remove.

Lets say I have a label with the text "_ _ _ _ _ ", some underscores. Now what if I want the program to locate the 3rd underscore and replace with something else. Is this possible? I was guessing by getting the character's position first and somehow there is a function that replaces characters by their position.

In winform's textbox, how to get the current key-in position?
For example -
textbox.text = 3056.98
If I type '7' after '0', current key-in position is 3.
In vb.net, which textbox event or keyword could I get this position value?

How do I get the current write-position using the BinaryWriter. I need to store the position in order to read from that position afterwards. (I know it would give the position where the next write would start, that will be taken care of).

i have a for loop "for each val in values" I want to within this loop some how check positions ahead of the current position for a condition. I am unsure how i can do this however apart from having an inner for loop to loop from the current position. If that is the case I am not sure how i can get the current position.I have attempted this with this code below, the inner for loop.
If creditPoints = "10" Then
Dim valcount As Integer = Val.Count
For intLoopIndex = valcount To Values.Cou

Imagine that I have a timer checking the current position, and always checking if it is equal to the duration of the sound.

I am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.
WPF, VB.net, .net Framework 4.0
Here is the code.
Public Sub FormatText()
If IsNothing(rtfContent.Document) Then
Exit Sub
End If
Me.rtfContent.IsEnabled = False

I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _
CallingConvention:=CallingConvention.StdCall)> _
Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?

I'm using VB 2010 Express with two instance of AxWindowsMediaPlayer in order to sync two videos (the videos are of the same thing but from two camera angles). Because the videos were started at slightly different times I've manually set the start time of each one using the following
AxWindowsMediaPlayer1.Ctlcontrols.currentPosition = 314.5093196
AxWindowsMediaPlayer2.Ctlcontrols.currentPosition = 237.1639908
The problem I'm having is that whilst the WMP clock initially displays the above times in each AxWindowsMediaPlayer, when I play the videos each starts a few seconds out from the stated currentPositions.
The video files are around 300MB each and when testing with smaller video files the problem does not seem to happen. I'm guessing the large file size is causing some delay and hence causing the problem.

On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?

Currently I have the code:textbox1.text = textbox1.text.insert(textbox1.getfirstcharIndexFromCurrentLine(),";")But this means it has to reload the entire textbox, which with large files is noticeable slow.What are the alternatives?

I understand that within a rich field text box you can search for a string and then format that string, but I am looking to change the formating of a certain position in a string regardless of what character is at that position.Can this be done in VB 2008?

I wanted to create a module / tool similar to MS word where user should be able to add controls, resize controls, drag and drop controls.Anyway, I have got lot of references on how to resize control, drag and drop add control etc...my main requirement is i need a way to add grid and should be able to add cells to it. When i resize the grid control, the cell height & width should get extended and compressed accordingly. Also i need to save position of the controls to a text file.Saving positon of other controls is easy but most importantly i need to save each cell position of the grid.
