Im using Asp.Net and VB on Visual Studio 2010. I am using a System.Web.UI.WebControls.TextBox with the wrap property set to "true", my problem is that when it wraps a word, it moves the whole word to the next line, what i want to accomplish is for the textbox to wrap, but not move the whole word, just move to the new line when the text reaches the right side of the textbox.
Example, imagine a textbox 10 chars wide.
This is what happens:
0123456789
I am a textbox
This is what I need:
0123456789
i am a tex
tbox
But if I set the wrapping to false, it just will keep expanding the width of the textbox on the same line. I was thinking of setting the wrap to false, and use the onTextChanged event to check the length of the text and manually trigger the new line. is there any easier way to accomplish this?
trying to move a lineshape (line), across or down my form, but not having any luck with it, I think it is something like this, (but it not quite right)

I am trying to test the Forward and Backwards capabilities.. but if you do the following:
Dim i = New Form
i.wbHelp.Navigate(New System.Uri("test.htm"))
i.wbHelp.Navigate(New System.Uri("test2.htm"))
i.ClickBackwards()
It doesn't run the DocumentLoaded or the Navigated() event until it is to late. To run integrated tests I would need to either wait for the result.. Or does the URI even get loaded at all if the Control is not visible?

View 5 RepliesI'm working on a .Net Windows application. All the controls arrange fine, but when the user specifies their Windows display text to be larger than the Windows 7 default of 'Smaller', the controls get moved around on the form and makes it unusable.
Is there a way to lock down those controls no matter what the display text setting is at?
I have created a form with a menu-strip containing sub-menus. The sub-menus will open on clicking the menu items but I am willing to display the sub menus on moving the cursor on menu items(mouse-hover). What will be the code for this? Is there any property in menu-strip to display like that?
View 1 RepliesI am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

I got a text file which I want to display on a text box. The text file has data sorted by date (the oldest one at the first line)
What I want to appear on the text box is just the opposite, the newest one at the first line, and I don't know how to do it.
Does anyone know how to open that text file and display it in inverted order?
Currently I'm writing a program that takes every 10 lines from one text file and writes them to another. I've never been good with For loops, so I'm having some trouble. I am not using any arrays for this program.[code]...

Here's my current code so far where rtb1 is the main editor, and rtb2 is the line display on the left side like in notepad++. So far my code allows for a number to be added on a new line in the line display when the enter key is pressed, however I want to know how I can get rid of those numbers whenever a backspace or deleted selection of text or the delete key erases a {vbLf} entry in rtb1 so that I can remove the integers on the left side accordingly to keep up with an accurate line count display. Also adding the number of "lines" (as integers/numbers) to that left hand display depending on how many {vbLf} entries there are in a pasted clipboard.Then that should cover everything about the line display, except for loading a document and automatically displaying the number of lines in the text. I believe i'd have to count the number of occurences of {vbLf} upon opening a document, but I haven't tried yet, so i'm not sure how slow or fast that would render opening a document.
I'm using visual studios 2008, VB9 and I am trying to write an app that basically performs calculations on a set of data input by a user. During the calculations, I want to display the data at each step, and have it retained in the display area on the GUI (not overwritten by the next data being displayed).
For example:
UserInput = 1
Do
UserInput += 1

I tried this, and other loop structures and can't seem to get things right. The actual app is a bit more sophisticated, but the example serves well for logical purposes.
I have a list box with information that needs to be displayed in a text box. Each of the lines in the list box has 2 types of information-Name and setup data. When I click on the line I need only the setup data to be displayed in a text box. This data on all lines begins at the 42 column. I can display the information using SelectedIndexChanged but the entire line is displayed. In other words I need to display only the data from the 42 column to the end of the selected line.

View 6 RepliesI saved a text file. The text characters were in RichTextBox iwth multiple lines. I used
RichTextBox1.AppendText(ControlChars.Cr) or RichTextBox.AppendText(ControlChars.Lf)
at the end of each line, but when I opened this text file using NotePad, all lines were displayed with ONE line. The strange thing is: if I open the same text file using other editors, .e.g. an IDE of Microchip or Freescale or Multi-edit...the text display had multiple lines as expected.
What should I do to make display as expected in NotePad?

I am still learning VB and operating VB 2005 for school. Challenging issue recently arose and would like advice from someone smarter than I .... When writing code to query several elements from a user,such as: Street number, street name, city, state, zip ... all posed as individual response questions. I want the ultimate displayed answer to show in a single line. When I write to code for that, I get the response in a single line, but they are all jammed together in the cout result screen display, with no spaces between answers (e.g. 2118Winona AveMontgomeryAlabama36102). I want a blank space to display between elements (e.g. 2118 Winona Ave Montgomery Alabama 36102). How do I cause the result line to include spaces?
