I've tried google a way to sort a table but couldn't get my code working.My program lets the user input enter information such as first name and last name in textboxes, once done they click on update button(so far everything works).On the top right of the form it has a Combobox and it displays a list of all the names of poeple the User inputed... but it shows it in the order the user inputed.I want to have a sort button so that way when the user clicks on "sort" it will alphabetically sort the msql table by last name and reupdate that on the Combobox (most importantly save msql with the new order of names)

I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

View 3 RepliesI created a windows form application using Visual Basic Express Edition 2008 but I did not know I could not use it on the web, which is what I wanted but being new to VB I just got a lot of headaches trying to figure this out. It works fine as a windows app but now just recently I installed Visual Web Developer 2005 to so I could create a web application from the windows app.
It is a simple windows application of a datagrid but now I want to run the same design application I made in Visual Basic to Visual Web Developer Express 2005. Is this possible? And, what do I need to do? I have all of the associated files in my project folder in Visual Basic Express folder.
how does look-up work in Visual Basic, I have done research on this but it does not explain. I have a Form1 called( Booking form) with 2 ComboBox's and 1 TextBox. each called (Destination_FromComboBox) and (Destination_ToComboBox) and (FareTextBox)and another form2 called (Fares Form) with 3 TextBox's each called TextBox1 (FromTextBox), TextBox2 (ToTextBox2), TextBox3(FareTextBox).So when I select (Booking Form) and Insert or select a Destination from (Destination_FromComboBox) and Insert or select a Destination To (Destination_ToComboBox) I want to read from (Fare Form/Fare Table) and give me the fare in FareTextBox on the Booking Form. Also on the booking I have 3 Radio Buttons
(RadioButton1 = 4 Seater Car, Normal Fare)
(RadioButton2 = 6 Seater Car, Time & HalfFare)
(RadioButton3 = 8 Seater Car, Double Fare)
But there is also a time Issue as well:
If the time is Between 05:00 & 23:59 then normal time should be used
If the time is Between 00:00 & 02:00 then time & half should be used
If the time is Between 02:00 & 05:00 then Double time should be used

I have this great way to use VB6 I treated my project like a .exe file.Say I want to work on c:work directory.I just save as the .vbp file to c:work directory
All the other files (.frm,.bas,.cls) files are in a special directory called library ALL of my .vbp files, in c:work1, c:work2, c:work3 refer to that one same directory.How can I do that in vb.net?
Why this is important? Bugs always happen all the time. If I just run .exe file, when bug happen, I cannot do a thing. However, if I run the project file and run the program in debug mode, when bug happen I can figure out what happen.
I am a CS grad, but haven't had much to do with programming since my school days as I went the BA route.Anyways, there are a few things that I do manually on the computer and thought that I could probably save time by creating an application for them.But I'm not really sure how to start.I'd like to be able to keep a history of Completed eBay listing so that I know when the price point is good and when it is too high.I noticed that eBay has an RSS feed, so I think I can do it. Just a couple of quick questions:
1 - Can I instruct VB.net to open a web browser and read an RSS feed, or would I need to manually do this myself and then run the application?
2 - What is the best way to work with RSS feeds? Should I convert the data into XML first?
I am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.

According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
temp = FM/TM
temp = temp * 100
percent = FM * temp
I have a simple application:Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
#If DEBUG Then
lblDebug.Text = "Debug"
#Else
lblDebug.Text = "Not in debug"
#End If
Now when I run it in VS, it prints "debug" like it should, but if i run the .exe, it still prints "debug". What do i have to do to get this to work right?
