Differences In Selected Text In Textbox And RichTextBox?

Sep 2, 2007

I have a form with a Textbox, RichTextBox, and a CopyToolStripButton.When I select text in the TextBox control, I can right click the mouse to get a menubox (cut, copy, paste, delete, select all) but when I select text in the RichTextBox and right click the mouse I do not get a menubox.Is this simply a difference in the controls, or do I need to enable a property on the RichTextBox to get this functionality?

This difference between Textbox and RichTextBox is evident even without the CopyToolStripButton code, so I am guessing it might have something to do with inherent or default properties of the controls themselves.At any rate,I would like to get this funcionality for the RichTextBox control as well.

Pan/change/move The Text Appended To A Richtextbox Control So The Text Itself Scrolls In Addition To The Scrollbars?

Jul 11, 2011

My application appends incoming report data onto a RichTextbox control.  As more text arrives from an external device, the thumb initially fills the trough and as times goes on, the thumb diminishes in size. This is expected behavior.A modal dialog box allows the user to cancel the file download but since it's modal, the user can't scroll down to see what the last text that was appended.Is there a property/event/method that will show the most recent/last text in the RichTextBox control, rather than the initial text as I have it displayed now? The user would be able to see the text drawn real time without having to use the thumb to accomplish

Asp.net - Pass Parameter As Text To JavaScript Function From .NET Code-behind

Mar 23, 2010

Basically, I have a gridview that is opened in a new window from the parent window. It has a bunch of records with a view button to view the details of each record (which stays in the same newly opened window). I have a calendar in the parent window that accepts a Date querystring parameter to set the current date on the calendar at page load. I'm just trying to refresh the calendar in the parent window to match the date of the label in the newly opened window.

All the code below is in the newly opened window. The .Net code-behind below refers to when that view button is clicked and everything is populated. At the end, I call the js to refresh the parent window and pass the value of the LabelScheduleDate as the querystring parameter. Now the label comes through as '03/25/2010' in the code-behind, but when I pass it to the js, it comes through as '0.00005970149253731343' in the end querystring. I'm not really sure what is making the value change, and I want to pass it as just text. Do I need to pass it as a string object? I tried but I don't think I was doing it right.

JavaScript Function
function RefreshParent(inputDate) {
window.opener.location = window.opener.location + "?Date=" + inputDate;
}

.net - Adapt Text Validation Function To Consider Selected Text?

Jun 4, 2010

I have this function which evaluates the contents of a textbox (or combobox or maskedtextbox) control and, in conjunction with a KeyPress event, will either allow or disallow the input. It is quite useful for dates or textboxes for which only numeric input is valid. It allows a set number of digits after a single decimal point, if specified in the function call. It also allows the backspace character if the textbox is full.

I would like it to allow me to input what would otherwise be valid text when the textbox is full but one or more characters are highlighted (and would therefore be replaced by the keypress character.

Trying to change the color of more than one of the same text within a RichTextBox. [Code] The above code searches for, and changes the color of all "Boat"s found in the RichTextBox. There are a few problems, such as: If you were to go back to edit the RichTextBox and place your cursor in front of the, now blue word, "Boat" and type then all of your text would be blue. Also, the text you wish to change the color of in the RichTextBox MUST be Exactly the same as: "Search1", aka "Boat", capital letters and all.

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010

Oct 12, 2011

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?

I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)

What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.

I have just started using VB, and from what I have found so far it seems like the tools you have is

- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function

As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

.net - WPF RichTextBox - Iterate Through The Text's Words And Change Their Content And Formatting?

Nov 1, 2010

I 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).

Change Selected Value / Text Of Combobx?

May 21, 2009

What I have been trying to do with no success is to alter the combobox during runtime from form1. In the textbox the text displayed always corresponds to the values binded with the combobox. I want to set the selected/displayed value of the combobox to be the text that is on the textbox. This to be done on a button click from form1. I have tried the findstring and findstringexact to locate the index of the corresponding text and alter but nothing. After so many testing I soon realised that if the combobox is at form1 together with the textbox I can do whatever I want with it. But when is on form2 I cannot do anything. When I mean anything I have tried clearing the displayed value with 'selecteditem = Nothing' with no success plus whatever else I try. [code]...
