Interface And Graphics :: Line Breaks In TextBox?
Sep 1, 2010
my interface is like this, i've put 4 text boxes above, followed by a Generate Button in the middle and a multiline text box below the Generate button (please see the attachment)
so all i want is when i click the Generate Button, i want the data entered inside the above 4 text boxes to display in the multiline text box at the bottom in 4 seperate lines and not in 1 row. Also i would like to have some line spaces.
this is the code i used
Code:
' This is used to display in Bold
OutputTextBox.Text = "" & TextBox1.Text & ""
' This is used to display TextBox2.Text
[Code]....
Just wondering, is it possible to put some tabs above the big multiline text box at the bottom, say like 4 tabs and each tab consists of a big multiline text box inside it. And then when clicked the Generate Button which displays different data ...

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)

I'm trying to rotate a mirror, which I represented by a line across a specific point. I translated the point of rotation to the center, rotated by an angle indicated in a text box and then translated it back to its original position.
Here is my code :
Quote:
HTML Code:
Dim theta As Single
Private Cntr_X_blu_Mirror As Single = 5
[Code].....
I hope the code is good. The problem I encountered is that the line becomes smaller and smaller as I rotate it. and that's bad! Sometimes it even grows longer [I think when I rotate it in the oposite direction!]
Also, when I rotate it at 90 degrees, the rotation does not resembles a 90 degree rotation. It seems to be inclined at 45 degrees instead!

insert images in a combobox. I understood the code, but what I'm asking is how do I add multiple images per line of the combobox?? I mean the way, the smileys are displayed in dropdown grid in Yahoo! messenger or the sort when you click on the smiley button..
I'm using Microsoft Visual Basic 2008 Express Edition with .NET Framework 3.5

I would like to build a line chart which can redraw or change during a period of time with dynamic data. So that the x, y axis will change if out of range. The graph may be somehow similar to Matlab. I am using vs2005.

I look at hundreds of VB.Net user interfaces through the internet and they all look horribly unsophisticated from a graphics point-of-view.Compare this to the backgrounds seen on tv broadcast that use blurred line gradients to create graphics that have some interesting appeal and draw the eye to them (at least my eye).I've attached some sample screenshot grabs below that I have annotated with magenta rects showing the interesting sections.What types of graphics routines can produce these types of graphic effects? The options that I have identified so far:
1.) More carefully done line smearing (see below..)
2.) Line drawing with a VB.Net version of the "Bresenham's line drawing algorithm"(as passel mentions in this post) (that might allow a specialized set anti-aliasing routines - like a wu algorithm).
3.) Line drawing with some Gaussian blurring as seen in the attachment to this post from my Perlin Noise thread.
4.) Possibly a gradient shaped by a vector GraphicsPath?
5.) Some other VB.Net gradient generating method?Possible the use of multiple passes with an alphafade brush?
6.) Last resort: manipulating the colors of individual pixels with lockbits marshal copying (highly undesirable).
I've done a fairly complete survey of whats out there on the internet for VB.Net samples for drawing lines to see if any of them combined line drawing with gradient effects and found very little.I played around with some code I found that did line drawing through mouse dragging and managed to achieve what I call the "line smearing" effect.I've attached my Line_Smearing_Demo below..As yet I have been unable to combine lines with shaped bezier curves,to produce Guilloche/Lissajous/complex Spirograph patterns like those seen on this page.

how can i automatically update my value when a user changs the combobox item. At the moment i have a button click when the user changes the combobox item and press the button the values get updated, everytime the combobox item get changed i have to repeat it click the button to update the value. I want something where automitically as soon as the combobox item selected the total value in the text box to change without clicking the button:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ComboBox1.SelectedItem = "Seafood" Then
TextBox1.Text = 3.5 * ComboBox2.SelectedItem
End If

I'm trying to update a text field... in this manner:The main form (where I have the design):
Code:
Public Class Form1
Public Sub ChangeTextBox(ByVal vVal As String)
TextBox1.Text = TextBox1.Text & vVal
[code].....
First I click on the button to open the port. Then I do this code so whenever I receive data from a serial port connection, "Hello" string is written in the text field.. I debugged it, made sure COM Port is open, and data seems to pass to the textbox.. because when I put my mouse over to display the values inside the textbox it shows that "Hello" is stored.. and I tried doing the textbox1.refresh() but still nothing happens.. the textbox remains empty!

Is there a way to enter text in a text box programatically, without the "changed" event being fired? Or do I have to use a flag to indicate that nothing should be done when the text is changed by the program?

I'm working with adding some user-friendly options to a program that I've developed. A lot of these require handling painting the control myself. So far this hasn't been an issue except for this case.In a context menu, I have a text box that a user can type into. However, the context menu doesn't seem to let me input a label next to it so that the user knows what the text box is for. So, I wanted to paint the text box myself but I can't get the routine to work.I have tried to put the following code in the paint event for both the context menu and the text box itself. In the paint method for the context menu, the string and the text box show up at the top of the menu. Not 3 items down like it should. Also, I don't think the end result is truly a text box.[code]I believe that txtRect is set to the rectangle for the context menu and not for the text box itself. If you run this code, "Filter By:" should show up at the top of the context menu.

I'm running Windows 7 x 64 and the latest version of VS 2008.I have spent forever trying to get the following VB6 code snippet to work in a VB 2008 Windows Forms application. The VB6 application works like a charm, even on Win 7 x64.Here is the relevant (I hope) VB6 code. It allows me to select text in IE8's browser window and then drag and drop it onto a TextBox called txtLink in a very simple VB6 application.
Code:
Private Sub txtLink_OLEDragDrop(Data As DataObject, Effect As Long, Button As Integer, Shift As Integer, X As Single, Y As Single)

I frequently use TextBoxes that expect date values. I do a tedious job every time to handle the Validating event. The Validation event ensures that the value is a valid date value according to the current thread's Calendar, and if so, formats the date to "dd-MM-yyyy".
I want a TextBox (e.g. DateTextBox) that automatically runs validation and formats its Text property. All I have to do is dropping it to the form.
I know I should use inheritance; but I do not know where to put the auto-validation code; and I do not know how to save the inherited class as a control in the ToolBox.

Problem drawing dotted path lines, with even dots along the path line.I want to draw a path line that can be any shape (square, round, outline etc), and along this path line I want even dots to appear.
I also want to be able to resize the shape (as in the example attached)This is very easy to do using "DrawPath" and defining points for the path and using a pen defined as dots.The problem I have is I want the dots to be evenly placed along the path, on any shape or size I draw.In the example I have created, I create a square with 4 points and draw a dotted path.There are 2 buttons that allows me to resize the square (larger or smaller) this helps show the problem more clearly.
The path starts at the top left corner and finishes back at the top left corner, the dots are evenly placed along the path, except the final dots at the end of the path. (Sometimes the dots are even and other times they are not even).The shapes I want to draw can be any size and any shape, but I have used a square in this example to show the problem I have. point me in the direction I need to go that allows me to draw the dots and give the impression that they are even all along the path, for all shapes and sizes.
In the pictures below if you change the size of the shape, one will have even looking dots, the other will not.

I got a program that generates 4 strings which I want to output to a RichTextBox. Getting them there isn't the problem, its getting them on separate lines I am puzzled with. As of right now, they are all just lined up one after the other, which isn't practical for what I need. I simply need 1 output per line, i.e.:
Output1
Output2
Output3
and so on.

How can I replace all types of line breaks (CR, LF and CrLf) using Regex?
Iīve tried different combinations of "

formatedString = System.Text.RegularExpressions.Regex.Replace(text, "

The following code does the job but it bugs my that I canīt seem to replace the Line Feed using Regexp.

I used to program with Visual Basic 6, so I have alot of old programs that I'm updating, plus I'm learning the new VB2008 methods. I'm writing a program that replaces the old "BitBlit" function which is no longer supported by Visual Basic 2008. It involves three picture boxes, one holds the sprite bitmap, a second holds the mask (silhouette) of the sprite bitmap, and a third has a background image.

I'm working on a design project where I have to use a Graphical User Interface that contains a drag and drop form. It consists of having a window dropped on a wall. Both of them are images to scale. I would like to know what kind of code I would have to use to show the x and y coordinates of one of the points of my window when dragged so when I drop it, I'm dropping in it on the desired coordinate of the wall.
