View 1 RepliesI have a rich text box full of encrypted data split by ";" and I have
Dim Pass, Data, Game1, Game2, Key1, Key2 As String
Dim PassEnd, Game1End, Game2End, Key1End, Key2End As Integer
Data = showencrypt.Text
PassEnd = InStr(showencrypt.Text, ";")
[code]....
Pass gets decrypted ok, and Game1 gets decrypted ok. Key1,Game2,Key2 are all the same as Game1 though. Is there something I am missing? Why is it setting all of them the same? I've tried settings the Start of the InStr's at the previous End but it doesn't work.

View 2 RepliesIn a .NET 3.5 application, i want to get caret position in a RichTextBox control. The RTB is not XAML. Also, the RTB doesn't have CaretPosition property as described here: [URL] What is the simplest way using which i can get the caret position?
EDIT:To be more specific i want to find out what is the position of the caret from the start of the line on which it is positioned. I can get the line number by using GetLineFromCharIndex(rtb.SelectionStart) but not the offset from the start of the line.
This is what I am trying but it doesn't work. The idea is to rest the caret position at the beginning after I hit enter and the conents od Textbox1 are deleted
Private Sub TextBox1_Keydown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then

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?

View 9 Replieseven Word Pad, when you scroll your Caret (the I-beam for browsing through text) through the text, in the font combobox, the font of the text you are browsing through will be displayed, and when you scroll your caret through a different font, the font will be changed. If you're confused, look at attatched picture.
I cannot seem to find a caret position changed event on the normal richtextbox control - and if anyone can show me a custom component with this it would help me a huge amount.So my basic question is how can i replicate the formentioned function in my own VB.NET program.No code is necessary just constructive suggestions, or links to other projects would be welcome.

I'm trying to make a TextBox with syntax highlighting (for (HTML/CSS) in VB.NET 2008.I figured that if I use RichTextBox.Find(), I can color specific text, but then I need to call RichTextBox.DeselectAll(). The problem is that the the cursor jumps to the beginning of the RTB.
View 1 RepliesI am unable to load rich text files into my rich text box. It worked fine yesterday, would there have been anything I could have changed by accident?
With OpenFileDialog
.Filter = "Text format (*.txt)|*.txt|Rich Text Format (*.rtf)|*.rtf|All files (*.*)|*.*"
[Code]...
but I am getting the error File format is not valid when i attempt to open any Rich Text file
Is there more elegant syntax for reading/parsing Size and Point objects in an Xml document?
Source Xml Nodes:
<objSize>{Width=64, Height=64}</objSize>
<Location_X>20</Location_X>
<Location_Y>20</Location_Y>
[Code].....
I have control over both the source nodes and the parsing code... So I am just being too lazy with my XmlNode creation? Regardless is there any benefit to using XmlConvert v.s. using integer.parse (or .tryparse)?
I have a rich text box which I use in order the user is able to add pictures, coloured writing, different font etc... however I need to load specific text in the rich text box when the user load the Form.how I can add (I guess) the HTML to load this every time the user load the form.
P.S the text will change depending on who loads the form so I can not do a simple
RichTextBox1.LoadFile("C:Documents and SettingsDesktopSigniture.rtf")
Let's say I have an RTB with the following text:
blah blha
nanna
nahei8
crap
more crap
I place the caret right next to "nanna", and using some code, I insert "NewData", so now the RTB is:
blah blha
nannaNewData
nahei8
crap
more crap
How can I place the caret next to NewData?
The Form Designer in the IDE is no longer working properly. When I create a new project, the Form Designer will work, but after I save it and close the IDE and reopen the next day the Form Designer no longer shows the form and instead says "To prevent possible data loss before loading the designer, the following errors must be resolved: An Error occurred while parsing EntityName.Line 2, position 62" If I click ignore and continue, then it just displays a blank form with no controls. The problem appears to have started after I unistalled and reinstalled VB2008 Express.
View 2 RepliesOn the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.
View 2 RepliesI'm Making a Simple syntax highlighter and I'm Doing the highlighting in the text Changed event of a RTB and for obvious reasons I can't re highlight the whole document each time someone presses a key so i highlight one line each time the text changes. But this creates a Problem. If someone pastes code into the RichTextBox It only highlights the last Line. So is there a way to get if the user typed the text in with his keyboard or pasted it from the clipboard in the text Changed event?
View 6 RepliesI have a question, how would i have a button, then when you click it, it puts the text at the text cursor in the RTF?
View 5 Replieseveryone! I've been at this for a while, and I'm not sure how this issue can be resolved:I'm working on a project in VB.Net, and I have a form with a rich text box. I have a groupbox with 4 radio buttons inside that are intended to change the font color of the text. Coincidentally, I have to repeat this same functionality for a 2nd set of radio buttons that would change the text font family.
At any rate what I've only been able to do is the following to successfully change the font color of whatever text I highlight in the rich text box:
Private Sub rbtnBlack_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnBlack.CheckedChanged
rtbxTextEditor.SelectionColor = Color.Black
End Sub
Private Sub rbtnRed_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rbtnRed.CheckedChanged
[Code]...
Is there a way that I could write a sub (I'm assuming I would use a sub, since I don't think I need to return anything, thus eliminating the use of a function) that would handle the action of changing the selected text color in the rich text box without having to use a separate sub for each radio button? Mind you, per my teacher's specs, she doesn't use a button handler for any of this.
is it possible to make first 60 characters in a rich text box a different color than the remaining text?

View 1 RepliesOkay, so what I want to do is directly output formatted RTF text to a Rich Text Box control in VB.NET. I don't want to find the text, select it and color it as it is not practical for what I'm doing. I've tried outputting RTF code but that isn't working either. Can I actually do this or will I have to write a dll?
View 1 RepliesI am working on an applictation to scan windows files to check for missing files, i have a couple questions on how to do this.I would like to use the %systemroot%system32 that way that it doesn't matter what drive letter it is, i'm not sure how to do this because when i tried it, it told me the file i was looking for didn't exist (in this case C:windowssystem32 undll32.exe) which does exist. Is there some way to use the %systemroot%?
Also, i am trying to print the resaults to a rich text box such as if rundll32.exe is missing put in the box "rundll32.exe is missing". How do I allow it to write it in the box, I tried the print command, but it didn't work.
I've been wanting to create a look like the attached jpeg Ive been looking around for a few hours for a solution to make text boxes transparent or have a background image. I've found a few projects on this form and elsewhere which include transparent text boxes, but every time I try to use it the way I need to--with the text box over a picture box--there are always various rendering errors. Most of the time, the text box is transparent if its just placed on the form (not over any other controls). But when I place them over other controls (like picture boxes), the 'transparent background' always take on the color of the form background.
This is one that I was trying to use. I found a few others around, but they all had the same render errors more or less.[URL]...I figured transparency or background images would have been supported natively. Anyone have any ideas? Maybe I missed something in my searches. I didn't really see anything which adds background images in text boxes (rich or otherwise). At this point, I'd just like anything that works, so it doesn't really need to have transparency--just a simple background image would be great.
How can I change certain text's color (like Visual Studio does with "Public Class" or "Public Sub") is inside of a Rich Text Box?
