View 1 RepliesI bound datagridview to bindingsource. The bindingsource has its datasource a collection Called Rates which is a collection of Rate items. The rate object has a property called VALUE. I need the user to be able to edit different values for the collection; However, on the datagridview, i need to keep displaying on one column called OldValue the existing Rate value before the change while allowing the user to edit that value in a second column called NewValue.
In other terms, One colum OldValue will keep the existing values from the DB before being edited by the user, this column OldValue is readonly. Another column NewValue will display, the 1st time, the old value from the DB (similar to OldValue when we do the Fetch from the DB), but it`s editable column, so the user can modify each value in the column NewValue without overriding OldValue cells. For now, I bound both columns OldValue and NewValue to the same property VALUE of the Rate object,

View 18 RepliesIm writing a program and its pulling data from a .MDB to put in a .DAT file.
Here is my while loop:
vb
database_connection()
sql = "SELECT * FROM tlalist"

In my database there are currently 6 rows. and only 1 row has the TLA_DAY column equal to 1, but for some reason when I look at the .DAT file it creates it outputs the result twice rather than only once.
Once JTLA_count increments it becomes "2", but the while loop still outputs as if its still equal to "1". Ive used breakpoints and the counter is incrementing fine.
i have a dice program that will find the random numbers according to user input as regards dice and throws required. My problem is when i have to display all the values in a listbox but in a horizontal type, were if a value came out more than once it displays the number and a bar for each time it come out and also at the end show the count of the times the number came out, to have a better idea the final chart needs to be displayed in the following format in a listbox as in the long run the program needs to run in a web application, but i am writing and testing in a window form application, then i will transfer to web application and use session variables and timers to control the output and the graph.

I have a database that has null date values in it. When I call the columns from the database with the null datetime values and display it in the datetimepicker text box using a dataset, theres always values in the datetimepicker text box. It sets everything that was in the database with null values to the current date. This is what i have..

I need to convert hex values aa 01 00 17 f4 2f (as contained in byte array FrameData) to display in a label control as AA:01:00:17:F4:2F
HexDump(FrameData(2)) converts the aa (which has been converted to Decimal 170) into 31 37 30 !
similarly I need to convert hex data ('02 00' contained in byte array FrameData) as
0x0200."0x" & FrameData(1) + FrameData(2) displays the data as 0x20. How would I convert the '02 00' hex data to display as 0x0200?
Normally I've been lucky to find someone who has had the same problem and applied their solution but after hours of searching I'm not able to find a solution to this one. I've got a FormView which is default mode set to Insert. When the page is loading I'm checking to see if the session variable which the formview datasource is set to has a value. If it doesn't I've coded in the onLoad that some of the controls in the InsertTemplate would be set to specified value.
View 1 RepliesI'm creating a game using vb.net and whenever the user inputs something to my program it displays the time and the time displayed until the user inputs something again the the time changes. I have my program display each individual timestamp but I would like to know if I would be able to save the values and all display at the end of my game in a new form.
The code I have is the following:
(in timer1=tmrReadInputs):
For I = 0 To 3
If (Convert.ToInt32(DataValue) And CInt((2 ^ I))) <> 0 Then
lblBitVal(I).Text = "1"
Else
lblBitVal(I).Text = "0"
TextBox1.Text = Trim(Format(Now, "hh:mm:ss tt"))
End If
Next I
tmrReadInputs.Start()
So when the value changes from 1 to 0, the textbox displays the time. How can I save the different time stamp values? I heard StreamWriter can work but I keep trying that and it doesn't work
I got 100+ textboxes that display record values. Most of the textboxes display correct values but several textboxes doesn't. These are the same textboxes. And they only display wrong values if I edit a record for the first time.

Tried to compare their properties and all but they are the same with textboxes that worked...

I am developing a form which needed to display 2 values from a combo . I have table Account with these fields Account_type, Account_name in this table. Even though I am saving only the Account_type in to a new table but when selecting from the combo, I want the account_name also display since the account_type is a code so that user would understand the mening of the acount_type. vb.net code that would display both the code and the account name to this. I used data binding to do this, it also displayed only the code.

When I look into my List of structs after this loop, none of the values were overwritten. Why? I thought that I had references in my list, so if I change reference A to a struct, then reference B to the same struct should see the changes?
what if you created a pool of numbers: 1 - 21 and then chose a random selection from the pool? Something like the following:[code]This gets rid of those messy if statements and all of those loops.
