I have an EXE that creates objects based on params passed to it.Say I have textboxes named 57 and 21.I want to read the values entered by the end user.
Var1=57.text
Var2=21.text
How do I pull this data from the boxes?
My project consists of a user interface designed in Visual Studio 2010 Express. I have it linked to an Access database. At this time, I have two text boxes that the user will enter a number. I want to be able to write a query that will take the first and second number and pull the information from the database that is equal to or greater than the user entered number
View 6 RepliesI Create an application that when a user enters a positive integer value in a input box(the default number is 10) when the OK button is clicked, the application should display a message box with the sum of all the integers form 1 through the value entered by the user. If the user enters a negative value, the application should display an error message. I believe I have to use a loop condition but I have no idea what to do.
EX: User enters 10 in the input box once OK button is pressed a message box pops up and says "The sum of the numbers 1 through 10 is 55". Use the following test data to determine if the application is calculating properly
VALUE SUM
5 15
10 55
20 210

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:

I created a usercontrol which has a Textbox and a Label. Setting the (boolean) textvalidity property we can toggle the icons on the label to show if the user has entered a valid input.

The problem is... when the control is used... the constructor initializes it to true (According to my code) so the icon is already displayed.
I've got a (hopefully) quick question. I've got textboxes attached to a binding source on one of my forms, and when I add, then clear, the data for the next entry to be added a small problem arises. If the user has previously entered something into, for example, Textbox3 and the user does not have the data for Textbox3 the user cannot move to the next field unless something is entered into the box.

Does anyone know of a good way to have a user enter an amount of time (hours and minutes) using winforms controls? At the moment I have two numeric up downs, one for time and one for minutes that I then parse to create a timespan. The only other idea I have is a text box that a user can enter a "00:00" time in, and validate the input. Both of these ways seem a bit bad (in UI terms) though.

I'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?

I have a question in relation to formatting text fro 24-hour time.
The format I require is always as follows 00:00
How can I make the ":" appear as soon as the second digit is entered as this is required to separate hours from minutes and also how can I force a 0 to appear for any numbers up to and including 9?
Examples being: 00, 01, 02, 03, 04, 05, 06, 07, 08, 09.
These zeros are required but may be forgotten by the user entering them into the textbox?

I have a Form1 with TextBox1 and Button1.
Here is what I'm trying to do: When Button1 is clicked, I want an Excel file created and saved into a default folder (the user does not choose the folder...code for Button1_Click will choose the folder), and the file name will be the text that the user enters into TextBox1.
The problem is this: I have two forms. One form and the other form do mathematical calculations. I want to save the values that the user inputs, so when the user quits the program and then starts it up again the values are still there. But when I open up the program, start typing in values, then calculate them, hit quit. Try to open up the program again, its giving me a message that the input file is invalid. When I click ok, the program doesn't crash, continues. But the values are not there at all. The other form I put exactly the same code, just changed the variables and it doesn't want to save the values at all! I wrote this code for saving and loading the values:
