I have a NumericUpDown control with a range of 10-50 and I want to have the selected number be multiplied by an amount of money to create yearly cost. I dont know, however, how to use inputted data from the NumericUpDown control in a statement because I cannot convert it to Integer and I also dont know how to call in the data even if a number is selected.
View 3 RepliesI'm letting users select a date/time for a scheduled task to run, using two NumericUpDowncontrols. I'd like one-digit values to be padded with a leading 0, so as to display 09:00 instead of 9:0.
View 4 RepliesSo I'm currently working on a control that acts as a HTML editor. One of the thing that I need to do is insert tables, in order to do that I needed to provide the user with some options first. When thinking of the design for this, I decided to go with the form layout that Word 2003 uses;
Now as you may notice the third NumericUpDown control has "Auto" written in it. This is one of the values the other values include;

how I might be able to get my NumericUpDown control (or another control) to display those non-numeric options.
I have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.
I have 10 values to compare against each other for duplicates and would like a recommendation to do this most efficiently. The values are associated with the NumericUpDown control. I'm using VS and VB 2010.
View 3 RepliesI have my numeric up and down control set up but there is one problem. When i run the application, there is an IBeam in the value box. I have got my alphabet and arrow keys mapped to other things so when i press them windows makes the annoying beep noise. How can i get rid of the IBeam from this control permanently? I have tried the read only setting but the beam is still there.
View 1 RepliesAs part of a program that I am composing, the user needs to enter a value by way of a NumericUpDown control on one particular form. Once this and other criteria have been evaluated, the program will then move to the next "step" of the program. If they use the spinner built into the NumericUpDown control, the event is fired on every change and that's all well and good, but if they double-click the value in the control then type the value in manually, it doesn't fire until the control no longer has focus. I can't depend that this might be the case however. Using the "KeyPress" event, I can in fact know when the control has focus and the user has typed but what I cannot seem to get it to do is to get the control to "read" these keystrokes as values until the control loses focus.
View 3 RepliesFor a NumericUpDown control in VB 2005, how do I distinguish between a change to the numeric value made by the user (by changing the text or clicking the up or down arrows), and a change made internally by my code? The "Scroll" event works for user changes to the TrackBar control, but not for me on the UpDown control, and the ValueChanged event doesn't distinguish the source of the change.

View 1 RepliesI'm getting a 'NullReferenceException was unhandled' exception when a NumericUpDown control is cycled too quickly.

I figure I need to ensure each image is happily installed in it's 'Box before I try to load the next one, or it may be that I just need to check that the last one is 'in' before I call the next bit of code (which calls this bit again if I'm too fast) It all works perfectly well if I don't go too fast.

I am wondering how to have more than one SQL select statement inside my window formapplication that will control the data flow, as i am a newbie in visual basic.net 2005. This is because I am working on a Alarm Application Notifier which will alert the guard on duty as well as inform him the alarm location. The guard's computer screen will be showing the premises and the button will blink at that location where the alarm is. So if the alarm is at block A for example, the guard screen will show block A button blinking.I have already done the first part but i am STUCK at the rest as to how am i going to seperate the conditions for the 3rd to 4th building .The bottom is for the first building code. The data is from the sql database.

View 2 Replies trying to write a simple app that queries an access DB based on date .. the SQL looks like this and works fine with a date hard wired into the select:
SELECT Terminal_ID, SUM(Transaction_Quantity) AS Total
FROM tblTransaction
WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > #1/1/2009#)
GROUP BY Terminal_ID
On the main form I have a monthcalendar control named 'FromDate' and a DataGridView control that shows the SQL results.
How do I get the user's selected date incorporated into the SQL statement that returns the results in the datagrid?
Something like:
WHERE (TransactionType_ID = 3) AND (Transaction_DateTime > Fromdate)
...but obviously there's much more to it.
I have made an app that will check to see if a website is on the 1st, 2nd, 3rd, 4th, and 5th page of google, the websites are in a datagridview. I am using five webbrowser controls but it begins to get slower and slower? As it searches for each website using a for statement. How to improve this code to make it run quicker, or even a better way to go about it.
View 8 RepliesI have a button on a web page that I just need a little help with some extra code. I think I need a TRY, CATCH statement?, this is what I have so far: I have a simple web page that has a button which at the moment when pressed enables the user to add data to a DB table via a stored procedure.Once this button is pressed a pop up message box is displayed to let the user know the data has been passed. The user then needs to press the 'OK' button within this message box which then directs them to the home page of the site. This works fine.
The code for this is here:
Protected Sub btnAddRawData_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddRawData.Click
'database conn, this is linked to the web config file .AppSettings
Using dbconnection As New SqlConnection(ConfigurationManager.AppSettings("dbconnection"))
[code]....
As I don't want the user to enter duplicate records in the database (This could be done by the user navigating back to the page where the btnAddRawData_Click is located and pressing it again.), I have created a UNIQUE INDEX named 'DupRecords' to stop the user from commiting this data more than once that day.When I run the web page now I get the following message in my browser:
Cannot insert duplicate key row in object 'dbo.GasRawData' with unique index 'DupRecords'.The statement has been terminated.The solution I think, is to add a TRY, CATCH statement into the btnAddRawData_Click code.
how do you make a statement that sets the focus to the txtPassword control?
