i wish to apply an input-mask or a format on an input box so it can check if the input data is an email or not.the inputmask/ format would be as folowing &&&&&&&&&&&& "@" &&&&&&&& ".com ".That is in Access but how to do it on VB.net and an input mask. Here is a part of the code which I use
Dim x As String = InputBox("please enter new E-mail" + vbNewLine + "eg.(username@domain.com)", "Change Email", My.Settings.Email)
If x <> "" Then[code].....
There are a number of textboxes I would like to validate. I first set up the key press events to only allow key entry's of characters which I feel are valid for this location (i.e. numbers and "." for dollar amounts). But in addition to this I would also like to ensure that the user entered something valid using an input mask. This may be a simple question but I couldn't seem to find the answer to it. If I have a input mask of ###.## and the user enters something like 4321.23, would this throw an error and if so, how should I set up my mask large enough so the user is able to enter large amounts.
how to create an 'Access-like' input mask for hastening date data entry.
Using C Pearson's much quoted code I've modified it as such: Private Sub Worksheet_Change(ByVal Target As Excel.Range) Dim DateStr As String[code]....
Note: I'm aware that most of the time I'm simply re-typing the original code - it was a learning experiencing and I also realised that the different American and Australian date formatting was less of a programming issue due to the systems being set up differently in the first place.My issue is having run tests using only 4 digit entry, all types of digit entry, with and without DateValue on the final DateStr, changing the cell format to text, to general, to date - always results in a code like "8811" (i.e. 08/08/2011) being changed into 01/01/1924 (approximately).
At first I assumed the use of "DateValue" in assigning the final .Formula value was forcing this conversion. However, with or without DateValue it still seems to read the figure as a DateValue and convert it as such.I'm sure it has to be something elemental that I'm missing given the scores of people I alone have seen on boards reading C Pearson's code and not coming up with another peep.
I am using VS2005 version of VB.Net programmer. I wanted to use the user input but most people tell me to use console...but I cannot use this function since my version is different, it will not show any results. I found that using mask textbox can use to read the user input but I don't know how the code can be written. I want user to input two number such as 1.345 and 2.355 and use this number for addition and give the answer. I not sure how I write the code for mask textbox to be read once user input the numbers.
I have a word (2003) document containing many Activex textboxes which are used to apply a character limit to the users input. Sometimes users want to paste data into the textbox from another source ks fine, but if they try to do it via the Edit menu then the textbox is deleted and replaced with the pasted text
Overreaching amateur developer that is outsourcing some of my work and doing part of it as well. I've been working on a dictionary/ thesaurus / spell check & suggestion application that I am trying to get to work on all applications within the windows environment.
I've used hooking to get key stokes and show output as the person is typing for definitions and spelling suggestions. This isn't accomplishing everything I want. Works fine for spell checking and suggestions but to click on a word that already exists or for touch screen interfaces to touch a word it doesn't work.
I was reading the Raw Input API on MSDN and thought that would work but my developer that I've hired is advising me that the RAW input's scope is only on the window that has focus and so cannot do low level hooking. I'm considering giving the effort but wanted a 2nd third fourth perspective prior to making the effort.[URL]
How would I go about changing the input mask in MS Access with visual basic code...I am using CREATE TABLE Here is the code of the code...The below code creates a new table with in my main database(.mdb) and changes the text property and makes it required, but I also want to be able to change the Input Mask to be password
vb Dim oConn As OleDbConnection Dim oComm As OleDbCommand
[code]....
This code works perfectly so far...I just can't figure out how to change the input mask..
I have a need to apply a mask to a string programmatically and not through any type of Masked Edit Control. So for example a mask of (###) ###-#### would need to be applied to a string such as 5551234567 to create (555) 123-4567.
I have 200+ text boxes in vb.net application. Let me make it clear all are simple text boxes. now customer demand to have formatted number value while input or viewing record. With Format() i can play for viewing but during add/edit mode in text box (While user typing value) nothing happened I want this result 1234567.0090 to 1,234,567.0090 during input.
or guide me any way by which i change all text boxes to mask textboxes through any tool or code.
I need some help with the input validation of my application. Attached is the code that I have written as well as a screenshot of the front end. I specifically need input validation to verify that the user selected input for cbLengthOfStay is a number between 1-10 as well as input validation to verify the user input for txtMedication, txtSurgicalCharges, txtLabFees and txtRehabilitation is a positive numerical number. Please feel free to critique my attached code. [Code]
If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.
I'm doing some homework for my VB class where I have to write a program that creates an invoice for a customer. I'm having an issue with converting the name input from the format of (Last, First) within the same textbox to (First Last) in a listbox via a function. I have done everything but dealing with the strings and I'm at a loss. I'm also having to create an invoice number with the first two letters of the last name and also the last four numbers of the zip code in an address line such as City, State, Zip. Manipulating these strings is killing me.Below is the code that I have written, manipulation of the strings must be in one function for each the invoice and the and the name issue....
=Dim custinvoicenum As String Private Sub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click Dim custname As String 'Name of customer[code]......
I'm having an issue with a page I created that was working fine two months ago. Nothing has changed in structure of the SQL tables and I have even done an insert within SQL to the table and all works fine with SQL. So the problem lies within the code. I'm getting this error: Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error: Line 71: Dim sv As String = grd.Rows(i).Cells(7).Text Line 72: ApproveManifest(sv, ffisID) Line 73: Insert(sv.Remove(0, 6)) Line 74: PushIn001(sv.Remove(0, 6)) Line 75: PushIn002(sv.Remove(0, 6)) [Code] .....
If I comment out line 73 and run it, I get the same error on 74. If I comment out 73, 74 and 75 the code runs to the end fine, it just doesn't insert the data into my table. It was working just fine and now it's not working.
I was tried to working with session. I have a login page, when user click the login button. i have save the User name and Password in the session. below are the code snippet on yhe login event:
Making a currency conversion program and I'm trying to run this code and I get an error saying that "Format exception unhandled: Input String is not in correct format". Then it points me to the line decUSDollars = Convert.ToInt32(strUSDollars) under Private Sub btnConvertButton_Click. I've looked all in my textbook and I can't figure it out.
My error message is as listed in the header "Input string was not in a correct format" however the stack trace is even more cryptic [code]...
This is worse due to the fact that nowhere in the project does it use "ParseDouble". I believe that this has something to do with the objectfactorylibrary but can't pin anything down.
I get the error when I submit the field without a value: "Input string was not in a correct format." I don't have any space or something else and String.IsNullOrEmpty(txtFoo.Text) returns true.
I am having some trouble with a DataBound TextBox with the Decimal DataType.
Here is the situation:
- I have a TextBox bound to a column in DataTable in a strongly typed DataSet.
- I have an ErrorProvider that has the BindingSource set to the same binding source as the TextBox.
- The Datatype of the column bound to the textbox is Decimal.
- I have my business rules set up as Partial Classes in the Dataset.
- I am capturing the ColumnChanged event in the Partial Class for the DataTable in question.
The issues are:
- The ColumnChanged event fires in all cases except when there is a data constraint. For example you enter non-numeric values in the TextBox.
- Once you violate a data constraint you cannot leave the TextBox empty even though the column is nullable.
In the above scenario the error icon appears beside the TextBox with the error "input string was not in a correct format." There seems to be an internal event triggering before my business rule logic is able to process.Desired functionalty:Bypass this internal event and present my own error message to the user using the business logic coded in the partial class.
I have a dropdown list which extracts data from my SQL database and gives the users two options to choose from (Weekly / Monthly). The database has an ID for each of these. Weekly is set to 1 and Monthly is set to 2. This drop down is linked to a gridview which extracts / displays the data based on the selected item. All of this works perfectly fine. This issue I have is that I want to add some code in my Page_ load event to populate a text box with the selected item. I would also like to set the dropdownlist as default to weekly when a users access thie page. I thought that the two following bits of code would work but I get the message 'Input string was not in a correct format'.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'This works fine lblTodaysDate.Text = GetDate() 'I thought I could complete an If Statement to get the text box to work. If DropDownList1.SelectedValue = 1 Then txtMeeting.Text = "SMC Weekly Meeting" Else txtMeeting.Text = "SMC Monthly Meeting" End If End Sub
I am new to .net but have read that I might need to convert my int to a string?
I keep getting the following error: "Input String was not in correct format" and it relates to the following line of objRow1 = objDataSet.Tables("tblStudent").Rows.Find(selA) I cannot grasp why this error keeps occuring. I have definately used this format (i.e. datarow = dataset.tables("tablename").rows.find(something)) elsewhere and have had no problems.
What I'm doing is reading the values in a listbox and trying to find their related IDs. The values in the list box are names from one particular table in a database and I need to get their IDs to save to a second table.
Within a project of mine I have created a group box that I am using to convert an input temperature from Celsius to Fahrenheit with the click of a button. The input is a text box value, manually entered. However, VB is giving me an error when I try to parse the string input of the text box so that I can convert the temperature values. I want the temperature to be converted for any values entered into the input box. Here is the code I am using...
Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click TempC = Double.Parse(Text3.Text) TempF = Double.Parse(Text4.Text)
[code].....
The error tells me that "the input string was not in a correct format"
The code works when I replace the input strings with an actual string, but again, I want the user to simply type in a value to the temperature box, hit convert, and then receive the conversions.
What is the best method to take a string from a textbox and verify that it is completely numeric (aside from the . ) and that it only has 2 digits after the decimal?
I have a problem with the code, I have input the valid username and password in the form textbox to input the strings in php, but it keep displaying the messagebox that says login failed.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MessageBox.Show("Please enter your username") ElseIf Textbox2.Text = Nothing Then MessageBox.Show("Please enter your password") Else
[CODE]...
I don't really know why it keep displaying the messagebox that says it failed when I have input the valid strings in the first place.
I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then Select Case e.KeyCode
[code]....
I can't get vb to recognize the above code it seems to skip right over it. BTW, is 'Keys.Crsel' the same as the caret '^' symbol?
My objective is to, instead of entering in the data manually into the text boxes, I want to read in a textfile. The Calculate button will contain the code to read in the file and assign it to the appropriate textboxes. Save the separate file in the \bin\Debug folder.
The text file just needs to have 3 integers on 3 separate lines.The code I posted works without and errors, but.I am having some trouble integrating the Stream Reader.
Dim E_ID As Integer E_ID = Convert.ToInt16(Request.QueryString("ID"))
But when it executes, I always get a FormatException:
error: Input string was not in a correct format.
What could be causing this?i am sending value like this.
