I am building a program where all the inputs (10) required from the user are asked on one form. Since it is not possible to let fields blank on the database, I would like to know how can I build an 'IF' saying that if all fields are full, then the database CAN save all the input. So that if there are any field blank, it won't save. I just dont know how to do the database condition. Thats all.

i have created a simple form which takes some input from the user. Now, I want that the input should be saved to my harddisk and can be seen later as well. Can you please tell me how to save the inputs as a record on my harddisk.
I mean the first time the form appears, it has four options. All the four options will be a record. The next time the form is re-loaded, then the same four fields will have data for someother client. It should be saved as another user.

I've written a program using Visual Studio 2008 Standard Edition in Visual Basic. It's a Windows Forms Application. The program is very simple, it just reads a directory of text files, parses the text and outputs another text file as .CSV file
for import into Excel. There's no user interaction required but it never displays the form and therefore the progress bar. If I put a GO button on the form and modify the program so that the subroutine that does the processing isn't called until the user clicks GO it shows the form and the progress bar etc. How can I make the program run at startup, show the form, show the progress bar and then pause for 10 seconds or so and then exit?

View 1 RepliesIs it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI have several text boxes which a user is supposed to input a numeric value and the program will use an array to verify whether the input in each text box falls within the numeric range allowed for that text box. So one text box will only accept number 3-7 and i'm supposed to create an array that will verify the input in that text box falls within that range. Personally, I would just do:
Dim intInput1 as Integer
intInput1 = CInt(txtInput1.Text)
If intInput1 >= 3 or <= 7 Then
messagebox.show("Input Verified")
Else
messagebox.show("Input must be a numeric value between 3 and 7")
End If
But this isn't what the assignment asks.
I have created a page that creates a number textboxes at runtime depending on the result of a database query, (ie one textbox per row in query result). My problem is that I can't for the life of me work out how on earth to access the text from the textbox that is posted back to the server by the user when they press submit.
View 4 RepliesI'm currently trying to improve the speed of my program. Basically the user inputs min and max values for a, b, c, and d and a constant n, and then it tries to find the curve/line in the form a (x/b + c) ^ n + d. However for large ranges (1-100 for a,b,c, and d; total of 100 million values to try), it would take around 100 minutes at the current rate (approx 800k values/minute). I'm wondering whether I can further improve the speed. [Code]

View 11 RepliesIs it possible for you to loop a block of code until the user provides a valid input? Like, when I click the save button, the program will prompt the user for an integer value, and I would like to validate if the user has inputted a valid value. If the user fails to input a valid value, then the program will re-prompt the same message again until the user inputs a valid value. Eg:
If MsgBox("Add copies to this book?", MsgBoxStyle.YesNo, "Adding Book Copies") = MsgBoxResult.Yes Then
Dim CopyQty As String = InputBox("Amount of copies to generate:", "Add Book Copy")
If IsNumeric(CopyQty) = False or (CopyQty < 1) Then
