Create A Button Which Basically Clears Entire Table In Your Database?

May 17, 2012

Is there any way to create a button which basically clears a entire table in your database?

I was hoping to have 2 buttons, 1 to empty a table 1 to fill the same table again.The idea is to store a year long values, and at the end of the year delete all of those with a button.The other button i want to use to fill the same table again.Starting from 1st day of the year untill the last day of the year.

'global' Type Timer That Will Allow To Basically Run Clock Entire Time Someone Is On Site

Oct 21, 2009

I'm in need of a "global" type timer that will allow me to basically run a clock the entire time someone is on my site, no matter what pages they go to. I've played around with the timer available for forms but I didn't see a way to make it continue to run after someone left that page.The effect I'm attempting to create is for a timer to start whenever someone hits my site, then every X minutes an event will trigger. This event should happen no matter where they are on the site. I've read a couple articles on timers but to be honest I'm fairly new to VB and I didn't know if I really needed to learn about 'threading' etc, to get a timer to work.

VS 2008 Add Buttons To Panel, Button/tab References Create/destroy Entire Tabs/layouts?

Feb 18, 2010

I need to know how to have a button on a tab to create another button on a second tab that contains a panel, with appropriate spacing, the same size as other buttons already present, and the name of the tab that generated this new button as the text on the newly created button. I.e. button1 on tab1 will create and place a new button on a panel in tab2 that already has a grid of buttons (maybe 3x10 buttons) which will be placed underneath a particular column with the text tab2 on the new button which can also refer back to that tab automatically. Hopefully we can get all this code under a single button event.

I also don't know how to have a button on tab1 that focuses on tab2, which sets the back button on tab2 with a reference to go back to tab1 in order to remain dynamic. I.e. clicking on tab1's button will go to tab2 and set the back button there with a link back to the tab it was referred from.

I'd also like to know if there's an easy way to create and destroy tabs with a specific layout. I.e. We have home tab, and comment tab. (This is for the sake of argument) On the comment tab1 (which contains all posted comments), we have a new comment button which creates a comment tab2 (or a dialog box for that matter) with appropriate textboxes, labels, and buttons in the right places which could also make use of the issues I posted above. So the new comment button on the comment tab1 will create either a new comment tab2 with appropriate objects, or a dialog box with the same, and then the submit button on this comment tab2 or box will create a new textfield/buttons on the panel containing the grid of buttons with the information provided in the fields from comment tab2/dialog box which is then destroyed.

I hope i haven't made the examples too confusing, but I can't figure out how to even make progress in these directions. Trying either fails completely, or semi-fails in getting these examples to function 100%.

I've already tried posting in other forums, but with no replies. Hopefully you all can help me figure this out.EDIT: This is not homework, I have scoured forums and google trying to find the answer to these problems. I'm hoping that because these are mainly VB based forums I can find some answers here.

Create Table Button Which When Clicked Creates A Table In Sql Server?

Sep 17, 2009

I am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;

Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click

[Code]...

This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.

Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.

Read Entire Table Into Array And Plot Rectangle

Jan 30, 2009

I have created several different colored 6 x 9 pixel rectangles (with a white border). I'm placing these rectangles on a large map, based on x y location and color code from a database. As I'm building the database, I occasionally run the program using the Debug in VB Express just to make sure everything is being place in the right location. I started getting an error when my rectangle count got up around 4500.

System.ArgumentException was unhandled
Message="Parameter is not valid."
Source="System.Drawing"

The release .exe works fine with no errors and a count of 6700 ... so far. As it is now it's taking near 60 seconds to place the 6700, and I'll eventually have 10,000 plus. (P4 3.20 GHz - 1 GB Ram). I'm placing each rectangle on the image as I read a row of data. Would it be beneficial to read the entire table into and array and then plot the rectangle?Would I be better off drawing each rectangle as needed or placing a my pre-drawn rectangle ?

Databound Radio Button Class When Database Table Empty

Apr 13, 2009

The problem I have is that many times, the dataset that this control is bound to is empty. Therefore, the user continuously gets an error saying that one or more fields is missing. When I debug the code, I can see the code in the class loop through all of the radio button controls on the form. Since none of them match the field from the database, the code throws the error. I assume the code expects a match.

Should I modify the class to handle the case when there is a DBNull value? If so, what would be the best method? Or should I approach this situation in a completely different manner?

Public Class myGroupBox
