Do multiline textboxes have a character limit?Someone who was using my program said that he has some textfiles that are about 50 KB and when he goes to copy/paste that data into a multiline textbox, he only gets about 31.9KB of the data.My MaxLength property says 32767, which basically matches the 31.9 KB, however, most of what I read on the internet says Multiline Textboxes can hold unlimited characters and that MaxLength is actually ignored when a textbox is in multiline mode.

how to receive and send variables between the call sign:
Sub ...
call Getsub(t)
end sub
function Getsub(ByVal t as integer)
end function
I think I understand how to receive t. Now t will be able to use in the function. How do you send back a variable from the function without the use of textboxes (say variable, x) ? Secondly how do you do it for multiple variables?

I'm looking for a way to convert a 5 character time representation to a date object. ie. "0937a" should be "6/16/2010 9:37 AM" or "1215p" should be "6/16/2010 12:15 PM".

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1

I am wondering if it is possible to take a string, split it at a certain character and then put the 2 parts in different text boxes.
For example:

1) Lets say I have three textboxes: TextBox1 TextBox2 and TextBox3.
Public Sub loopthing (ByVal input1, ByVal input2, ByVal input3)
For i = 1 To 3
TextBox(i).Text = input(i)[code]....
I know that the (i)-thing will not work, but my question is if it's possible somehow to set the three textboxes text to different variables using only one line of code (Like my attempt above).
2)How can I do so that when I click a tabpage on runtime, a certain textbox is highlighted and ready to write without a mouse-click?
I've tried the tabpage's GotFocus- and Enter-events, and writing
TextBox1.Select()
there, but it only works the first time I enter that spesific tabpage.

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If
Next
What i'd like to do is isolate the textboxes only, is there a way to do that? I tried this but i got an error:-
For Each box As TextBox In Me.Controls
If box.Text = "7777" Then
box.Text = "Found"
End If
Next

Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.

I am running Visual Basic Express 2005. I am trying to develop a program to send morse code out the serial port. I have created working code that can determine which character needs to be sent and toggles the RTS line on com 1 with the proper pulses. What I can't seem to figure out is how to be able to type in characters at a higher speed than they will be sent out the port, so as to be able to use the backspace key etc.

I am not sure if I should put in a Text Box or not but this is how I thought it might have to go. Textbox1 shows the start time of a procedure and textbox2 shows the endtime of the same procedure. I would like it if the textboxes were in a 12 hour clock showing an am/pm tag on the textbox's. Then in Textbox3 it would show the differance between Textbox1 and Textbox2 in Hours and Minutes.

I have a form with many different textboxes on it. The form is used to Edit the data already in a databound table. At design time I set my Databindings.text to the appropriate columns.
During form load I check the values in the bound column for null values. If the column value is null, I set the textbox.text property to a descriptive prompt like "enter telephone #" or enter city. I also use databinding.remove to remove the databinding so that the desriptive prompts don't wind up in the database.
Here is the code I use to remove the databinding.
For Each Panels In Me.Controls
PBox = TryCast(Panels, Panel)
[CODE]...
.Tag2Defaultphase is a custom property I have defined which holds the default descriptive prompt. If the user enter a value into the textbox I then wish to add the bind back so that when I updateall with the tableadapter the value will be transferred back to the appropriate bound column.
Here is my code for that:
Sub perOptionalTBoxValidation(ByRef TBControl As custTextBoxControl, ByRef strDefaultTextPhrase As String, ByRef intMaxChars As Int32, ByRef bsBindingSource As BindingSource, ByRef strColumnName As String)
[CODE]...

I have set up a simple quiz where you drop answers to the correct question. I have implemented a system where the are 18 text boxes (9 for questions, 9 for answers) and it can be customised but I want the questions to be able to be 'saved's since it in another form the if I give them special names when I close the form and open it again it has lost the values. Is there a way to remember the variables for a set period of time (cookies?) or if not just for that session?
