View 2 RepliesI got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes.

View 17 RepliesI'm working in visual studio 2005 and developing a windows form that has a datagridview on it.
One of the cells is a Calendar Column type (custom made). I pulled the code for it off the internet - it basically allows the user to select the date from a small calendar.
When the date is changed, it gets the correct value and it also saves into the database with the correct value.
The problem is that it doesn't load onto the grid with the correct value. In fact, no matter what date I enter in, it always displays it as 1 day earlier. e.g. If I saved it to the database as 4/19/2012, it displays it as 4/18/2012.
I verified that there's no other column in the query that retrieves the data for the grid that contains the value it's displaying.

I have a form that allows users to enter information into a few textboxes. When users click save, the information will be transferred into the datagridview.
My problem now is, for instance, there is a textbox called "Price" with the datatype "money" which users are only allowed to enter numbers. If users enter alphabets, errors will occur. I don't wanna use try catch, I would like to try different methods such stopping users from entering anything into the textbox when the datatype isn't correct - nothing will appear in the textbox when users hit all the keys in the keyboard except for numbers.
Using this
TxtBox = New TextBox()
With TxtBox
.Name = "T" & reader("area").ToString
.Visible = True
[code]....
The name would come out like "T3" Now I want to put a value into that textbox.How can I address the correct Textbox?

I have a table and I want to select a field in it and then display it in a text box
something like:
SELECT userName
FROM userTable
WHERE (userLogged = 'ON')
how can I display the selected username in a textbox?
BTW the userLogged indicates wether the user is logged in or not
if the user is logged in then the userLogged will be changed to "ON"
if the user is not logged in it will be "OFF"
I know it's not that practical but I'm still practicing.

Create an application for maintaining payroll for a business. When your program begins, read in an input file containing delimited employee records (a sample is provided in the assignment); each record contains the employee name, the current salary and the number of years employed. Display only the names of the employees in sorted order, and when the user selects a particular employee, display the salary and number of years employed for that employee, allowing the user to edit the record. Provide methods of adding and removing employee records as well, and update the input file with all changes before the program close
I want to put the salary and years into separate text boxes. Heres my code so far, I realize its certainly not the most efficient way, but its functional.

What I am trying to do is create a rather generic file opening form.
I am creating a visual basic form to prepare a file to open. I want the user to select the open button, get the dialog to open the file, then I want the exact file path for the selected file (C://Users/text.txt) to be pasted into the the textbox immediately below the button. The textbox is also to allow the user to type the directory that they want to draw from. So he actual opening of the the file will commence once another button is pressed, once the directory has been decided upon via either the openfile dialog or by pasting the address.
how to reference the root directory of an application. I want to the openfiledialog to the directory of the application.
I have a listbox that is connected to a text file and this file is created when the program opens for the first time and then users can add data to the file as they wish. However what I am having a problem with is that how can I link the selected item in the listview to a textbox.

I can read data from the serial port (GPS receiver). Its just 2 lines of data every 0.5 seconds. Whats the best method to read the data and display it in a TextBox?
If I use:
DLdate = SerialPort1.Readline()
Then I don't get the new line character, and it just over writes on just one line of the TextBox.
Also, should I time the grab of data, or is there a better way? Should I create a buffer, and when the buffer is full then do a write?
