I'm entering 123 into a field and getting 231.It's because I'm formating the text as I change it.
Private Sub txtObject_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtObject.TextChanged txtObject.Text = Format(Val(txtObject.Text), Zformat)
End Sub zformat is "0.0"
Initially the field is "0.0". If I highlight it and type "1" I get "1.0" the cursor is now in front of the "1",I then type "2" and get "21.0" and the cursor is in front of the "1",I then type "3" and get "231.0".
It is because the cursor is in the "wrong" position.Is there a simple way to fix this?
I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.
i want to prevent users from entering numbers and other characters such as (_,"*&^$#).... into my textbox-u know what i mean! I want my textbox to accept only alphabets. I have written a function that is able to check the numbers but i don't know how to check whether the text contains those special characters. Here is my code for the numbers. i'm sure, just as i'm able to check the numbers. i'll be able to check for those characters.
Public Function ValidateText(ByVal GetString As String) As Boolean Dim Count As Integer = GetString.Length Dim i As Integer
The app uses several forms to let the user enter information. In each form the info is entered into textboxes and dealt with elsewhere when the "Enter" button is clicked. A lot if the info entered is used in calculations and so must not contain alpha characters, only numbers. What is the best way of examining each entry and identifying any that are not numbers, so that I can ask the user for a correction with a MsgBox?Prevent Users Entering Letters Instead of Numbers?

I got an email I just created using Outlook automation and I need some help to get it formated nicely:set Font of the body set font-style to bold of certain words insert a picture into the body (this is not an attachment) when putting text in the body using VB.net looks like outlook automatically adds spaces for each "paragraph", how can I get rid of these spaces? how can I get my signature on because it disappears when text is added to the body [Code]
i would like to enter data from a textbox called textbox1.text into my access database called Stocks.mdb. Browsing the internet, i have gotten close but still cant get it to insert the correct data. Currently my code is:
My aim is to insert commands in to a console such as command prompt (except it isn't command prompt its actually a console engine for a game) and the commands will have shortcut buttons aswell which I can do my self, not a problem. My actual problem how ever is that I dont know how my vb form would recognise the process it needs to type in and how it would even find the text box to auto type the pre configured commands which I would have configured inside my form.
I want to make it so I have a form and a button and a web browser. The web browser will automatically load to a website that has boxes to fill in. In google chrome when i right click on the text box i can find the element or whatever its called. I am just wondering how I can make it so when I press the button it will change the text of the textbox on the website to whatever I want. Also how to make it press a button on a web browser as well.

I have this test form where I'm testing the idea, but ran into a snag. Now the main idea is to load all the data from a dataset into the one column of the datagridview. This works perfectly as shown in the image. Now there is something that I want to happen, but just can't get it right. when on the DataGridViewComboBox Column I also want to be able to type in my own data if the one I want is not available in the combobox.
Also if there are 50 values in my combobox and 2 of them are: jacky, jacson When I type jac, I want the combobox to only give me the options starting with "jac"
Here is the code that I'm currently using: Dim dt As DataTable Dim dsNewDataset As New DataSet() Dim i = 0, intSetArray As Integer = 0 Public Function JT_PullDataWithCOLUMNS1(ByVal Cols As String, ByVal TableName As String) As DataTable [Code] .....
get data like the pitch and volume of the sound currently being "heard" through a microphone?
Do you know the little graph which the Windows 98/XP sound recorder used to show? It used to show the pitch and volume of the sound which was being recorded. Like I want to get the data from that.
Basically, I will start experimenting this stuff by showing the volume of the sound entering the microphone in a label. And maybe the pitch too.
I have a data-bound combobox that pulls values from a BindingList(of T). Combobox loads fine, correct values are displayed (I'm not using SelectedItem or SelectedValue). I'm using properties and connecting the data to the control via a bindingsource.
What I want is if the user types text into the combobox, I want the data from the bound table to change to that new text, i.e. edit the bound data directly.
Easy as pie to do with a textbox, but can't seem to get a combobox to work this way.
I was trying to use the validated event of the combobox to write the data to the datasource, but it doesn't fire when I press enter. Is that the way to do it? Can I not link the data to the combobox directly?
Title pretty much says it all. Does anyone know a way to to prevent a computer from entering a low/non-processing mode while the program is running? I don't care about monitor modes, screen-savers, hard-drive spindown, etc (in fact, I'd prefer to leave those alone; I like it that it shuts the monitor off after a time period).Basically, I have an industrial program that needs to continually monitor a PCI card it uses for IO; and this activity alone isn't enough to convince Windows not to go into Sleep mode. We normally just shut the power-save features off, but we had an incident where a technician forgot, a customer's machine went to Sleep after the end of the shift, the pumps stopped recirculating, yadda-yadda big mess.
I have a richtetbox and i have it so that the user can change the font and the font color, does anyone know how i could get it to print with the formatting (font, size, color)?
I am using the DateTimePicker control in a Vb.Net Windows project.I would like the date to reflect the Regional Settings on the user's computer, but also to show the month name, rather than the month number.For example, if my computer is set to English(US), I would like to see Nov 26 2009, and if my computer is set to English (NZ), I would like to see 26 Nov 2009Is this possible?
I have a datagridview and need to do some formatting to it. On load the row 0 column 0 cell is highlighted. I need users to click on datagridview to select a value. The issue is with the initial load highlight it looks like the first row is already selected when in fact it is now. How can this highlight be disabled? Each row of has 7 cell, the user is able to select any of the cell of a row and the corresponding row ID is selected. The issue is that only that one cell is highlighted.
I would like the entire row highlighted regardless of what cell in that row is clicked on. One of the columns is a status value. I would like to color the text based on the value. For example if the Status is opened I want the text to be red, if the status is closed the text color should be default.
I am working in VB.Net and trying to use Regex.Replace to format a string I am using to query Sql. What Im going for is to cut out comments "--". I've found that in most cases the below works for what I need.
Have a bit of code ported from VB6 to VB.NET. It uses Write and WriteLine all the way to produce output files.
Now, I need to compare outputs from original and ported code, but there's one tiny problem with number formatting. For instance whereas VB6 code Writes just .5, the VB.NET code produces 0.5, instead of .0005 (in original) it writes 5E-4, etc.
How can I make VB.NET's Write to write numbers in the same format as VB6? The option of refactoring writing code to include formatting step is not acceptable.
Have a column of dates which i need to compare to a specific time of the year, which establishes what calculation needs to be applyed then depending on the outcome apply conditional formating to highlight an adjcent cell, but need to remove the YY element as the contents spans multiple years.
if the date in A1 is between 1st Jan & 14th Mar use -8 if the date in A1 is between 15th Mar & 15th Oct use -17 if the date in A1 is between 16th Oct & 31st Dec use -8
Then deduct the above value from B1 to give a target for each row (from 3 onwards)if the target is < the value in n then change background orange in f
