I am looking for logic that converts an incorrect user input to a correct integer input. For example, a user might mistakenly type in letters within an integer input and the logic changes that input to the correct form(integer).
View 3 Repliesi just want to make a program with first form to enter the serial if correct just continue to form2 if incorrect just a popup say like "Serial Incorrect" how i can make it ?

I want to add a counter for my program that basically counts the times I answered correctly and incorrectly. When a user adds or subtracts correctly the correct label shows 1 and when a user correctly answers again the correct label should show 2. It just adds and adds until the program is running. Same goes for the incorrect label.
View 1 Repliesi am creating a quiz which would be 20 questions for software design students and may use alot of code.my first problem is the score for the test, i know a friend of mine can add up the score but he cant move onto the next thread until you have got the question correct which is sort of cheating, i want to know how you create a variable and make that variable stay in all the forms and add up the score of correct and incorrect answers and come up with a final score for the user in the end.
View 8 RepliesPart of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following:
a) group number is neither 501 nor 062
b) number of units are NOT numbers
c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?

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:

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
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.

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.
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".

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.
With the following snippet
Foo = IIf(String.IsNullOrEmpty(txtFoo.Text), 0, Integer.Parse(txtFoo.Text.Trim))
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.
I have some custom user controls in my .net winforms program that do not display correctly when the user has selected larger text size. This setting:
My controls look like this:
Instead of like this:
The bill to area and ship to area are both custom controls. I don't know if this is contributing to the problem but I do have code in each to scale the phone/fax areas to stretch nicely, like this code from the bill to control,
Private Sub panFaxPhone_Resize(sender As Object, e As System.EventArgs) Handles panFaxPhone.Resize
panFax.Width = (panFaxPhone.Width / 2) - 1
panPhone.Width = (panFaxPhone.Width / 2) - 1
panFax.Left = panFaxPhone.Width - panFax.Width
End Sub
How can I get my controls to size correctly while still respecting the users choice for larger text (I don't want to just set the AutoScaleMode to None)? After playing with this for a long time it seems to be a problem with anchors in the child controls. See this below image, the inner black box is the control with its border turned on, the text boxes (like name) are anchored left and right and should stretch to fill the control, but don't.
I have a dynamic webpage that loads a user control multiple times, including loading the user control within itself as many times as needed. Within the user control there are four controls: Title Label, Repeater, Placeholder and within Repeater a AjaxControlToolkit Rating control.
The structure can look like the following:
Webpage
Placeholder
UserControl (repeater hidden, no data)
Placeholder - [UserControl]
[code]....
how do I efficiently loop through this type of structure to find the rating controls?
Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.
I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.
HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.
HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

When I attempt to read my Xml file when using a schema file I get the following error message:

I am building a program for my CINS-113 class where it allows the user to enter a number 1-15 in a masked text box and then hit OK and it will display that number in a ListBox as such:
Say they enter 1...
1 X 1 = 1
1 X 2 = 2
1 X 3 = 3
...
1 X 12 = 12
I have gotten everything to work great, but when you enter anything but numbers 1-15 it properly provides a message popup telling you that your entry is basically not the right value, but then I get a build error that says "Input string was not in correct format" and it highlights my line: "intInput1 = Convert.ToInt32(strInput1)"

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.
