Validation For Input Mask?

Aug 10, 2009

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.

Excel 2003 - Date Input Mask ?

Aug 10, 2011

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.

C# - Raw Input API Scope Of Use In Windows 7 / Vista OS - Can It Apply To The Entire Environment Or Just On The Focused Window

Aug 25, 2011

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]

IDE :: Input String Was Not In Correct Format

Sep 17, 2009

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 75: PushIn002(sv.Remove(0, 6))

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.

Input String Not In A Correct Format

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.

Input String Was Not In A Correct Format?

Oct 26, 2009

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.

Input String Was Not In Correct Format

Apr 12, 2012

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

The Input String Was Not In A Correct Format

Jul 28, 2010

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.

C# - Double ParseDouble - Input String Was Not In A Correct Format?

Mar 11, 2011

I keep receiving this same error about 3-4 times a day and have had no luck tracking down how to resolve this issue. According to the stack trace, the error is occurring within the Microsoft.VisualBasic library so how exactly would I go about fixing this issue? Here's the report I send to myself and what gets generated by the server. Any suggestions would be greatly appreciated.

[Code]...

Update: I understand what the error is and what would cause the error to occur. The problem I'm running into is finding out where exactly this error is coming from within code. The stack trace tells me its coming from Visual Basic but there's nothing else. No line numbers, no other info about what function caused this error to occur, there's zilch to go on so I'm left scratching my head trying to diagnose something, that looks to be wrapped up in a .dll probably.

We're running Ektron 7.6.6 sp2 if that sheds any light onto the subject. Is there any way to get a more robust stack trace? I checked the event viewer on the server and the info i posted earlier is all that's displayed in the event viewer. Which is none to helpful.
