The code I came up with ALMOST works... but almost is not enough.
1.) all 3 of my richtextboxes have the same quantity of lines, always.
2.) When I scroll one of them, I want them all to scroll in unison, as if they were 1 richtextbox.
Here is the code I have that ALMOST works right....
Public LastLineNumber As Integer
Public HighestVisibleLine As Integer = 16
Public LowestVisibleLine As Integer = 0

I'm still playing with my program that has multiple RichTextBoxes. What I want to do is to be able to save the data in all these boxes (only about 10 characters max in each box) to a simple text file and then reload the saved data into the exact boxes they came from at a later date.
View 5 Repliesi am using visual basic 2010 and i want to open and save multiple richtextboxes text into one
file.
for ex
richtextbox1.text="Deepak"
richtextbox2.text="My Name"
but i want to save these informations in one file.
I have an application which I've designed to relay information on a large screen, like news feeds etc. It scrolls labels inside panels so the text moves in a readable fashion. It actually works quite well but it seems to struggle sometimes by consuming too many CPU cycles. I've turned on double-buffering on the form as I remember this graphics method from years ago. This improves the display drawing in general but I am still getting flickering and sometimes the scrolling slows down considerably.

After scouring the articles online I have come up with this design for a winforms based touchscreen app that needs smartphone like scrolling. The app itself will run on a tablet laptop or touchscreen desktop.I put everything I want to scroll on a panel. Set autoscroll to true (which will show scrollbars)Now put this whole panel inside a groupbox.Shrink the groupbox until the scrollbars are hidden (visually hidden, not visible = false)
Now the fun part I am stuck at.I think I have to handle the mousedown, mouseup & mousemove on the panel to set the autoscrollposition so that when someone touches the panel and drags, it does it's scroll magic. Please help fill in the few lines of code in below method stubs. The msdn doc on autoscrollposition is very confusing since it returns negative numbers but needs to be set to positive with abs and what not.

View 2 RepliesHow do I combine richtextboxes? Currently, I am directly saving rich text to a RTB with ".rtf" and I would like to append the rich text information to that box from another RTB. Something like: RTB.rtf &= newrichbox.rtf do not throw any flags but also does not work. What I am ultimately trying to do is save multiple richtextboxes to a single RTF file. I was trying to do it by combining them all into one RTB and using ".savefile()" or is there a better way? Maybe appending them to the file one RTB at a time?
What I'm doing is generating a report, so I have built generic rich text templates that go into multiple RTBs that will create the form sections and I have left placeholders for the data I am adding, so I do replaces on the placeholders to insert the data. However, there are a couple dozen different possible formats for the report based on user options, so I built each section into its own RTB so I can just write out the relevant sections when it comes time to generate the file.
How do I add tables to a RichTextBox in VB.NET 2010?
I've tried adding the tables by using RTF codes, but I can't get that to work. And there is nothing like richTextBox1.AddTable() which would make things very simple. At least, if there is, I haven't found it.
How can I make inactive textboxes / Richtextboxes autoscroll? I have Multiple richtextboxes that are constantly being appended with data automatically and at the moment only the one that is active scrolls and all the others stop when the fill up. How can i get round this?

View 6 RepliesI'm working on a project in vb.net 2010 that has 3 RichTextBoxes. Two of the RichTextBoxes can be loaded with text from text files. How do I take the multiple lines of text from each RichTextBox and combine them into the 3rd RichTextBox.
For example, if 2 of the RichTextBoxes contain the following lines of text:
(RichTextBox1)
Monday
Tuesday
Wednesday
(RichTextBox2)
Jan
Feb
Mar
I want the 3rd RichTextBox to show following result:

I have 2 richtextboxes on a form and I want to link their vertical scrollbars i.e. ifrichtextbox1's scroll bar is moved then richtextbox2's scroll bar moves by the same amount.The reason for this is that both richtextboxes will contain almost identical text barring a few differences in the second richtextbox. By linking the scroll bars my hope is that the user can better compare the textboxes for any differences between them. I have looked at trying to find a scroll bar property but can not find one. Does one exist?
View 1 RepliesI have some text in an .rtf file which uses a non-English character-set (it's chinese).When I open this in Wordpad or Word I see just the chinese characters.When my app opens the .rtf file and reads the file's contents and puts it into a RichTextBox for display, I get "everything" from the .rtf file, i.e.:

I have a number of questions about richtextbox.
1. How do I change the font by clicking a button.
2. Also I want a Find control but how do I get it to find it then select it.
3. Lastly I am having a Find and Replace where it finds the text in a textbox and then replaces it with what ever is in another textbox.
Well, I have a MenuStrip1 with submenu "Open File1" and "Open File2".
An OpenFileDialog1, two RichTextboxes and a button called "Check".
When I open txt files into RichTextboxes, by clicking the check button i want it to compare the two contents and focus the differents with a color (let's say yellow).
I have created a simple project and at the end it only says with a MessageBox if files are the same or different.

View 5 Repliesi need to create an array of richtextboxes called rbox, and position them in a tablelayoutpanel called tlp.
i have these snippets of
dim rbox(10) as richtextbox
tlp.Controls.Add(rbox(i), 1, 1)
i know that the second line of code has the arguments of (control, row, column). the row and column is good because that allows me to place them in the table and i need this but the control part doesnt work.
for an application, I generate RichTextBoxes during runtime with the following code. The code generate a new node in Treeview under parent node "Notes".
Dim RichTextBoxCounter As Integer = TreeView_MainForm.Nodes_("NodeNotes").Nodes.Count
Dim NewNote As New RichTextBox
NewNote.Size = New System.Drawing.Size(845, 550)[code].....
Now, I want to show the RichTextBox if the associated child node is selected. I tried the code below, but it does not work.
If TreeView_MainForm.SelectedNode.Text = "Notes" Then
Dim NewNote As New RichTextBoxPrintCtrl
If TreeView_MainForm.SelectedNode.Parent IsNot Nothing Then[code]......
provide the code to display the RichTextBoxes after selecting the node.
When I downloaded VB 2005 Express I took advantage of the bundle of goodies on offer and downloaded SkinCrafter Light.I really like the four skins that come with SkinCrafter Light, and I am using one on my current project (example of the skin I am using here). However, SkinCrafter Light has a couple of bugs with RichTextBoxes (these bugs are known to SkinCrafter, as I can see posts about them in their forum, but they have gone unanswered in over two years!)One bug is that any text that is colored in a RichTextBox is turned back to black when the skin is applied, and if you click anywhere in the RTB the application will crash (you can see my RTB on the right bottom of the form in my screenshot above).
I use colored text in my RTB, but, at a pinch,I could make do without (as I really DO like the Skin), but the problem remains of crashing when clicking inside a RTB.I was wondering (can't test at the moment as I am at work) if simply placing a control, such as a Button, Label, Picture box etc, set to transparent, over the top of the RTB, would solve the problem, so a user could not click inside the RTB (but would be clicking on the invisible control over the top instead).
I have a Richtextbox with many lines. The data is as follow:
[Z=100, A=10, B=20, C=100]
[Z=100, A=33, B=50, C=255]
I want to split the lines to 3 new Richtextboxes, with the A, B and C values + the line number. Should maybe not be so hard, but I got stuck.
This code extracts the A, but obvious only the first line.
Dim values As String
values = RtbAll.Text
Dim Rawdata As String() = Nothing
Rawdata = values.Split(","c)
Dim s As Integer
For s = 0 To Rawdata.GetUpperBound(0)
RtbRed.Text = (Rawdata(1) & Environment.NewLine)
Next s
Ok, so I done some reading and searching and I am confused on what is the best way to print my form that has 2 labels, 2 richtextboxes on it on get it to print to a 3x5 card or 4x7. I had this built in vb6 and used a picturebox but that method doesn't work in .NET. So what is easier, printform or printdocument or DrawString. I tried the printform but I don't want the whole form printed. Also read about DrawString as well. Honestly, I am confused on all of it.
View 12 RepliesOn 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

ctl.Text = "found the sevens"
End If

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

I have a form which has a horizontal scoll bar, a vertical scroll bar, and a panel. The 2 scroll bars move the panel. When I execute the form, the panel will scroll under the horizontal scroll bar when using the vertical scroll bar. But it scrolls over top of the vertical scroll bar when using the horizontal bar. I don't understand why 1 of them goes over and the other 1 goes under. Is there some property that controls this? Or some way to that 1 set it up wrong? The vertical scroll bar is on the left edge of the form , to the left of the panel, and the horizontal scroll bar is near the top of the form, above the pane. Can anyone direct me as to how to get it to stop scroll over this bar?
