When I enter a vb.net textbox, if there is data in it, I want it to be highlighted. I looked around and couldn't find a property that would do this so I do the following:I built a little subroutine that does the highlighting and then call it from the ENTER and CLICK event on each text box.

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Here is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.
View 1 RepliesI have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.
recommend a book that focuses on the .NET framework in general and isn't too language specific.
View 3 RepliesI have a textbox on a form that when it loses focus it updates other text boxes on the form. But before it updates the other textboxes I check the input value in the textbox lostfocus event if it is undesired I return focus to the the textbox and alert the the user with a msgbox. However where my problem is, is that when the cancel button is clicked I don't care what the input in the textbox is because the changes are being canceled but if the value is undesired the it keeps returning focus to the textbox instead of canceling the changes. Is there a way to see what control was clicked on before or in the lost focus event? Can't seem to figure it out tried enter and leave events but no luck!
So for example something like this...
Code:
Private Sub TextBox1_LostFocus(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If Control that was clicked <> btnCancel then

Looking in the "Display Items" list in the "Fonts and Colors" section of options, I don't see a way to color code dates. I can color numbers, strings, comments... all kinds of stuff, are Date and DateTime hiding under something else?
View 1 RepliesI've been looking everywhere for a solution to this problem. I'm new to VB, well programming in general, and am using VS2010 ultimate. Everything has been running smoothly until recently. For some reason, there is no syntax highlighting for my code. All other code is highlighted and colored correctly, just VB is not. All i get is black characters. Keywords, comments, everything is black! I have attempted to reset all the settings, and I have made sure that the font settings are all set to default.

I am using this code for syntax highlighting in RTB and it works pretty nicely except for the flickering part.
VB.Net

words.Add("<p>")
words.Add("</p>")

How would I prevent Rich Text Box from flickering?
I have a richtextbox on my form and currently have made a simple syntax highlighting for it. It works great with a small amount of text but as the text amount increases it starts flashing and locks the textbox while typing.
This is my current code. I call the sub on the textchanged event.Basically what happens is I have a list of words that it checks for and if it finds it, it colors the word.

View 4 RepliesI recently set up a Redmine server for my time. Redmine's Wiki uses CodeRay for syntax highlighting. However, most of my team prefers to code in VB.NET, which CodeRay doesn't support.Are there any plugins out there that offer syntax highlighting for VB.NET in CodeRay? If not in CodeRay, maybe through some other library (that could be integrated into Redmine)?

I have two textboxes. Each textbox contains lines, where each line contains comma separated values. When each line of a textbox does not match the number of comma separated values of the other textbox (ie if line 3 of textbox1 has 4 comma separated words and line 3 of textbox2 does not have 4 comma separated values) I want to highlight the line which does not match the other textbox's line.
This is what I got so far (and got stuck!)

test1 = testA.Lines(k).Split(",")
test2 = testB.Lines(k).Split(",")

I want to search as text is entered into a text box. All works as it should. When the search highlights the first character of the string then ALL following searches have this same color.
For example: I have a listbox with a list of titles. As I move through the titles the RTB displays the story line associated with the title.
RTB = "A big brown box and an apple is the mystery" Search for "a" (All conversions to common case) will highlight all the "a"s. BUT when I click on the next title, ALL the text is now highlighted.
There have been many variations tried and all without success.

Each time I click on an item in the list, that item is highlighted in Blue. When I click on another, the highlighting transfers to the new item and the previously selected item is green. The HideSelection has no effect on the highlighting, nor does transferring the Focus to another control. How to get rid of the blue highlighting as the only way I have found is to click in the listview control below the data which is counter intuitive.
