I have a RichTextBox with an OnChanged event. The OnChanged event should look at each line in the RichTextBox and if the line is of prime length colour it red, otherwise colour it black. How do I do this? I think it is possible to select from index a to index b and set selection colour, but I think this will lose my cursor position.
View 2 RepliesI'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string?
For example. The txtboxCodeEntry looks like this:
If strVar="dummy" then 1 else 0 Endif
I would like it to "autoformat" to:
If strVar = "dummy" Then
1
Else
0
End If
The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE.
I was using VB6 and all my text formatting is stored in a database from the way VB6 stores it. How do I apply this formatting to a rich text box in VB 2010?

View 1 RepliesI have a MaskedTextBox using the mask "00/00/2�00" to restrict input to a format of XX/XX/20XX, with the Text property bound to MyBindingSource.SomeProperty of type DateTime.
Recently, values with a single-digit month or day recently started displaying incorrectly. I expect that the ToString() method is being called on the value at some point in data binding, and I believe the call is not padding month / day with zeroes.
I tried setting the format type of the MaskedTextBox.Text property to DateTime in the advanced data binding properties, but it didn't help.
How can I apply ToString("MMddyyyy") when converting the DateTime object to a string, before the value is bound to the Text property?
I am currently working on a VB.NET project and the hardest thing that I am having trouble with is that everything is black and blue. Having worked a lot with C#, I really like the way that types are colored differently.
I have tried going in and having a look at the "Tools > Options > Fonts and Colors" and the various "User Types" under "Display Items" is set to a different colour but its not reflecting that colour in the text editor.
I am making a html editor in visual basic 2010 for Uni and i am coming across some problems.
I'm using the richTextBox because it is more editable for what i am doing. The first of my questions is: How can I change the colour of text.
What I have done so far is add a timer that will constantly check to see if the user has entered... lets say "<div>" then i want that text to change to a different colour... say red.
My second question is: Obviously in web dev when you write the <div> tag you have other content inside it like: <div id=""/> so how can i make the entire string between the < and the > or the <div> </div> become the same colour.
I am building a word pad clone with extra a few extra features. I am trying to get two combo boxes (one with font names, the other with font sizes) to apply their selected attribute to the selected text in a richtextbox. This was my latest attempt, and I think I'm starting to get close, but I still get an error for InvalidCastException - Conversion from string "" to type 'Integer' is not valid.
[Code]....
I got two combo boxes, one has numbers from 1-75 and the other one has all system fonts. I have a richtextbox as well. I basically want the user to be able to choose the font and font size from the combo box and then apply to the richtextbox. However I want about two functions. If the user has highlighted selected text then changes should only be applied to the highlighted text, if the user has not highlighted an item but changes fonts or font size, then the changes should be made to the next characters inputed. How can I do this?

I've developed a MySQL chat app that I have in my program. It works perfectly, however all of the text is the same color. I use a silver-on-black scheme. I'd like to do 1 of 2 things, whichever one is.. er.. "more possible". The first option would be simple - alternate each row's back color. So that one row would be silver-on-black, the next row would be black-on-silver, and so on alternating. Each row is separated by a "vbCrLf". The second option would be to merely bold or turn to white the info text. Here's the format of the chat messages: [{time} - {user}] {message}. I would want [{time} - {user}] to be bold and white. Are either of those 2 options possible? Well, I know they're possible
View 1 RepliesHow to copy the text in a RichTextBox along with its formatting to a wordpad or webbrowser?
View 1 RepliesI am trying to bind a RichTextBox to data from an XML file where text within a paragraph may be tagged with formatting tags. As an example the text may look like this:"The size of the area is 5000 m<superscript>2</superscript>".Text may also contain other formatting tags such as <bold> or <italic>:"The quick brown fox <bold>jumps</bold> over the <italic>lazy</italic> dog".
View 5 RepliesI have a RichTextBox. I process all the formatting and everything works fine. There is an exception. When I have selected text that have two states of formatting in it, the SelectionFont member is set to Nothing. I notice that WordPad recognizes this condition
and kindof greys out the affected format.
Let's take this example:
This text is in Bold.
The rest of the comments here and not in bold.
When I select these two lines, the SelectionFont gets set to Nothing. WordPad sets the Bold button grey, but still clickable. If I click the Bold button in this state, the entire selection is set to bold. How do I achieve this same functionality?
i am trying to display a line of smiley faces ☻ and change the colour of each face, i cant use a find method as there are 10 of these smilies so i thought about using a loop and selecting only the last one entered and changing its colour. here is a simplified version of my
VB.Net
For a = 0 to 9
RichTextBox1.Text += "☻" ' add the smiley
[code]....
This when i ran it changes the first nine to the first colour in the array and correctly does the colour of the last smiley? could i for instance format the character first then add it formatted?

View 1 RepliesI have an Emailer in my Application and it has a richtextbox which the user can add fancy colours, font, pics etc... but when I send the email it doesn't send it as HTML.

Using VB 2008, I have a form which includes a richtextbox which is bound to a database field. When i bind the datafield to the richtextbox, I get an unformatted display unlike the control in VB6. How can I bind the data from the database to the richtextbox so that it displays formatted?
View 1 RepliesI have a rich text box in one of my applications (WPF). Now I want to store the data of the rich text box along with its formatting (e.g. bold, colored etc.) into a database (SQL Server). Currently I am storing the whole XAML of the text box in a database field. however, I am not sure whether this is the right approach.
View 2 RepliesI have two RichTextBoxes, each of which can have any sort of formatting. I need to be able to take the rich text from box 2, complete with formatting, and add it to the end of box 1, preserving the formatting of both box 1 and the appended rich text.
I've not managed to find anything usefull on this anywhere apart from hints pointing to manually re-building the RTF codes for the result (but no actual VB / C# / C code to perform this or similar).
I have a richtextbox with multiple colored text in it. When I change the font, the color table is removed and everything changes to the default fore color. Anyone know of a why to preserve the color table and formatting when changing the font? I know I could build the RTF manually, but I really want to avoid that if possible.

View 7 RepliesI have a WPF RichTextBox which contain in its FlowDocument both text and images. I need to iterate through the text's words (those which builds the text which the user see on the screen) and change their content and formatting. For instance, change the word "room" to the word "home", applying to the last a red color.
I need to change words whether they are formatted or unformatted.For instance, if a word is in Italic, colored, or just regular black text, it makes no difference for me.Each word will be replaced with one which have about identical length, so I don't want that this operation will effect the general page layout. All images and other objects should remain at their positions.It is preferred that the process of this operation will not be visible to the user. Only its result should be visible (i.e, no visible selections of text).If this operation can be done either directly on the FlowDocumet or with properties/methods of the RichTextBox, the simple one is preferred (but exmaples for both will be ideal).

I am creating a multi-user application using VB 2005 Pro and SQL Server 2005.I would like to know what your ideas are when it comes to managing user permissions in regard to being able to view, add, edit and delete information in the database? Do you think I should have the end user type in the information into the VB application which then will create an SQL server user and then apply permissions to that security user or should I fine-grain the application by allowing groups to be created and then assigning permissions and users to those groups?
View 3 RepliesSo - I have some text in an RTF control. I want the user to be able to highlight text and apply an attribute. The following code is placed into a button called BOLD and seems to work nicely:
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Bold)
End If
The code above will turn the selected text bold.
But then the user selects the Same text and with the following code placed into a button called ITALIC it removes the bold attribute and replaces it with italics.
If rtfText.SelectedText.Length > 0 Then
rtfText.SelectionFont = New Font(rtfText.SelectionFont, FontStyle.Italic)
End If
Since the users actions are separate - I can not know that they want BOLD and ITALIC, so how do I make sure I keep the existing attribute on the selected text (which, by the way could be part bold and part not-bold) and add italic?
Somehow I need to add the italic attribute to the selected text, not simply replace all attributes with italic.
Is there any way to change the colour (background colour or text colour) of just a certain item or item(s)?
