I have an application that uses the editable dropdown combobox (comboboxstyle.dropdown)
But when I run the application, whenever I entered a new value that is not in the list, it disapears when i focus to other cells.
is there a flag i can call to validate the text entered in to a databound combobox?
My situation is that i have a combobox where users can type in whatever they like, but OnLeave i'd like to ensure the value in the combobox is one of the items in the data that its bound to.
i'm avoiding a listbox because the suggest/append creates a nicer interface while they are typing as it shows possible matches.
I have an windows mobile application. In the windows form of it, I have a combo box.I load the values in the combobox on frm_load event.Now we all know what the combo box has the facility that it allows to enter text as well as chose from the dropdown.So when they enter the text, I want to validate it against the list that is in it.If not then msbox error.
My loading of the combo box is here.
Private Sub mainfrm_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am automating Word from VB.Net.I open a document by:
Dim msWord as Word.Application = CreateObject("Word.Application")
Dim doc As Word.Document = msWord.Documents.Add(Template:=Path)
where path points to a template file I created with a header and a watermark. The template has some bookmarks which I want to dynamically set to some appropriate text values:
doc.Bookmarks("DocumentTitle").Range.Text = "The Joy of Office Automation"
If I comment out that line, the document opens in Word with the watermark, etc, in place. If I let that line execute, it inserts the text as appropriate, but the watermark and other things disappear from the document. You can actually see it flash briefly, and then disappear.FWIW, this is Office Word 2007, and I am opening a .Dot (Word 97-2003) template. The Bookmark.Range.Text I am setting is in the document header.
So, I need a way to email information entered into a textbox to an Email address through the .exe itself after pressing a command button.

View 2 RepliesIs richtextbox can save a text within its control? What control in vb.net that could save the text being entered within its control paticularly, if any? I need somebody that could give me an idea on what control to use to save the text within the control. I'm not trying to save the text anywhere. I want to save it within the control. I don't have to save it with a filename and a path location. Just like this forum, which everytime you post and reply to a thread, you will have to enter your message in a certain workspace and after you submit, it will save within the control so everytime you open your thread you will see the messages. What control do I need to use in vb.net to do that?
View 1 RepliesI have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or
(IsNumeric(txtEntered.Text) = False) Then
MsgBox("Sorry, but letters are not allowed!")

I'm building an app that does calculations (in dollar amounts). I want to buildin a constraint that says the value entered into text box must be greater than 0. If the user does not follow this rule, I want them to get an error message.I have the calculations built and the error message, but not the constraint statement i.e. if users enter negative numbers the ouput is negative, which in the context of this app makes no sense. how a statement that would require the value entered into a text box to greater than a value.

I have this program I'm working on, and I was wondering if it was possible to disable/enable TextBoxes when specific words are wrtten. I tried doing this, but it errored. I'm a new programmer to VB, I just started a month ago, and I'm doing this for fun.
If TextBox1.Text = "Shutdown" then TextBox2.Enabled = True
I also want it so that you don't have to press a button to identify if it is the right text, so it could "scan" automatically.
I'm working on an application to write reports for the work I do. I have a Grid filled with Textboxes inside a Scrollviewer to input data for the report. I am using the arrow keys to navigate around the grid. The focus moves to the expected Textbox when the arrow keys are pressed but if I press any other key it is immediately followed by a Tab to the next Textbox. Even a Tab is followed by another Tab. Following is the code I use for the navigation.

Dim focusDirection As FocusNavigationDirection
If e.Key = Key.Right Then focusDirection = FocusNavigationDirection.Right

I have a program in which a user enters a sentence in English into a text box, then the sentence is translated into French and German based on words in an array of structures that gets its values from a text file. I have almost all of the program written, but I am a bit confused on how to get VB to get the English words that are entered into the text box separately so they can be translated individually and the value returned. I need to use a Sub Procedure to get the English Words and to Translate them. [Code]
