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
View 2 RepliesTrying 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.

View 4 RepliesI'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.

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).
I've been trying to convert my VB6 code to VB10, I'm stuck on how I should write it so I can pass a font name to my

I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?
View 4 RepliesHow do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
I am using a RichTextBox control on my form. I want a small code which can detect if any image has been inserted in the rtb or not. (IDE VS 2008)
For e.g. user can just type some text or insert image also (Ctrl + V). Now if we select an image then we can get the type but I want a code which scans contents of rtb and gives me a true if an image is inserted or false if there is none.
Is it possible to paste an image in VB's richtextbox like we can do with Word or Wordpad? I have tried all the tutorials I can find online and am still having no success getting an image from the clipboard to the RTB. I can accomplish it if I already know the image and path etc. and do it through code, but that will not allow someone to simply click an image, copy, and paste it into the rtb.
