Saving / Displaying TimeStamp Values In New Form
Apr 25, 2010
I'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 have a form in an application that I'm building and in it I have a datagridview that when a user clicks a checkbox on a line in the datagridview and "submits" the data, then the form will insert all of the data on that line (along with the code "Holiday") into a database. Currently if I click in the checkbox on any line other than the first line and put a line break on the "Try" statement, and then fire the submit_onclick event, I'm never reaching that break point but if I click on the checkbox on the first line and submit that data, that works and it behaves at I stated above. Here is the code as it stands currently:

Basically I have a form which is used for a report, when completed it is then mailed to various mailboxes. I would like the option that if the user cannot complete the form, they can save it & reload the values into the form to use later.Some of the boxes will have quite a lot of text, so using the registry is not an option. I have looked at My.Settings but think this is for application settings not user input such as a lot of text - but I could be wrong.I've looked at freefile & got it to work with text boxes saving to a .dat file, but had a problem in that text appeared in the wrong text boxes so I assume the order was different in the load to what it was in the save?

I 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,

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.
3 ||||||||| - 9
5 ||| - 3
6 ||||||- 6
10 ||||||||| - 9
2 | - 1
My code till now is that i have a class were a roll dice method and a similar values method are kept and from the form in the roll button these two methods are called and the results are shown in two listboxes one for how the roll dice random numbers with duplicates is shown and the other listbox displays only the numbers without duplicates.Also another method for the graph is in the class clsNDie but it seems that i have something wrong it this area?

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..
DateOPStartedRevisionDateTimePicker.Text = ds.Tables(0).Rows(0).Item(13).ToString
I just cant figure out a way to get the datetimepicker text box to display nothing if the values are null in the database.

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.

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. After correcting the wrong values in the textboxes the first time, they display correct values in succeeding editing of records. 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.

Have read most of the null value posts here, and I have managed to get things working as far as a "next record" button for my database application form (there's some awesome advice on this forum!). I have just one question, though. How do you manage saving of blank text box values from a form? I am using JET, but when I try to save an updated file that has a null value, it is not letting me. I got around it by forcing the text boxes with null values to contain " ", but obviously this is not the bext solution!

My windows form as a bunch of textboxes on it that basically let the user put in different positions/forces that a test cycle then uses. I am trying to let the user save their profile settings/open the settings so they don't have to input the same values every time they want to run the same test. Here is my code so far. basically, when i save my csv file, and open it, all 6 textbox values are plopped in the first textbox instead of being distributed to their original boxes. I just read about a "split" function

We have a listbox in our MVC View and the user has the ability to highlight multiple values. I'd like to be able to save those selected values(if possible?) as a comma delimited cell value in our '08 SQL Database.
The image below shows what I am attempting to explain. Note the selection in the LISTBOX
This is where we save the passed in values from the Positionnumber DDL (Listbox w/ mulitple highlights).

Now the user wants to ad 10 more states to this or remove these 3 and add 5 more. so u basically get the idea. the table in database looks like this -ID Color State_id
There is a table called states, so stateid shall come from there. so how do i do a loop insert or update in vb.net?
