While loading the page, the error was thrown as "input array is longer than the number of columns in this table"
Part 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)?

View 1 RepliesI have a txtbox(for barcode).. if i input a item number in that txtbox and if that number will match in your database, the other information(shall we say, product type, item ID, etc..) will display in my other txtboxes..
View 5 RepliesI am trying to draw textboxes when the user enters the amount of textboxes to be drawn on one form and the textboxes get displayed on the another form. I have found these codes online but it works with inbuilt codes I guess. That is, the number is already hard coded in the form.

I have an existing database that I want to add a number to that the user inputs. So lets say that in the database there is 4 carrots, and the user on the addinventoryform inputs 3 carrots and pushes a button. Now I want that number to be added to the database number so in the database there would now be seven carrots. I am using an oledb connection and cannot figure this out.

I currently have a windows service that is packaged up as an msi installer. However, during the installation i need the user to input their required filepath (to string) location. The filepath variable currently resides in my component class called MyNewService that is inherited from System.ServiceProcess.ServiceBase.
Is there anyway i can allow the user to define the filepath variable during installation?
I need to get the user input for where they want the files that will be produced by my windows service to be stored.
I was thinking that i could do this by reading in the user's input to a variable in the on start event of my service? this variable is then later used in my xml writer.
I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush
Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:

We're in a strange situation with a legacy winforms VB.NET 1.1 application using ASMX web services. Trying to send a user Token from a WindowsIdentity object as a parameter to a WebMethod. I will be adding a 'HACK: comment. System.Security.Principal.WindowsIdentity.GetCurrent().Token
The token is of type IntPtr, the first problem is the WSDL being generated doesn't support IntPtr with the error of 'unsupported type'I'm aware this is a big WTF question and sounds insecure, so any simple helpful alternatives are welcome but there are a lot of constraints on how we can change this system, including complications with the hosting environment. So I would just like to get our piece of data over to the web service to save a lot of other headaches.

The system we have in place at work for call centre agents to input telephone numbers doesn't validate their input, so, in a lot of cases, we have junk data being entered (0000000000 as a phone number generally). I've been taked with fixing this, but I'm not sure how to stop the agents entering junk like this.

I was about to create a program about CPU Scheduling (SJF Nonpreemptive), Now, I want to ask the user to input the no. of processes ,then based from the user's input I would display exact no. of text boxes where the user could enter the value for each process then store it in an array. But I don't know how to code the text box., I'm new to VB.net and I'm used to it's 'drag and drop' nature. I just want to know how the code to output this text boxes. and is it possible to have an array of text boxes?

Form 1 for the USER INPUT OF THE NO. OF PROCESSES
Form 2 for the output of TEXT BOXES
I'm attempting to learn VB in college. My first project is to create a program in Small Basic and then write it in Visual Basic. I'm looking for the equivalent of TextWindow.ReadNumber() from Small Basic in Visual Basic. I want to force the user to input a number not letters. I'm writing this program for the Console. Is this possible? During my testing I entered a word instead of numbers and the program crashed.

Actually, I wanted to validate the todayMonth textbox just to input number between 1 to 12. The problem comes out when I do this procedure : Lets say I input an interger 11 and it passes the validation and proceed to another textbox. Then I click back to the todayMonth textbox, it shows this error :
"Conversion from string "" to type 'Integer' is not valid."
I don't know why my value in the textbox is "null" or empty . I still saw the value 11 on the textbox.
