VS 2010 Returning Entire Row From SQL Table To Combobox?
Apr 11, 2011
I am designing an clock-in/clock-out program as a learning exercise. So far I can type the name of an employee and add them to my timeclock database in a row called "EMPNAME". The issue I'm having now is that I need each of those employees in column of EMPNAME to appear in a combobox when I hit "GET LIST". Is there a simple way to do this using a SELECT statement for the commandtext? I've tried to google but cant find exactly what im looking for.

This is the code I have set up to scan a directory of files:
Dim fileArray() As String
fileArray = Directory.GetFiles(System.AppDomain.CurrentDomain.BaseDirectory & "help")
And it successfully gets all files in the directory, but it gets their absolute paths as well. For example, one of the entries in fileArray() is:
F:ProjectProjectinx86Debughelpook_troubleshoot.html
And I want it to just be:
book_troubleshoot.html
Is there a way to do this without parsing through all the array entries to trim off the path?

I coded in it along time ago, back in middle of the 90's, but not heavily, so I don't remember that much, and never really worked with databases or file import/export. I'm trying to write code in to take my table or recordset thats active and export it to a XLS file.

All I want is to enter text into a databound combo box. If the entry is not in the list, then the user should have the option of updating the table that the combo box is bound to.The way I have set up the project is by dragging objects from the toolbox and having the application set up the datasource through the data sources tab. This in turn creates the bindingsource, dataset and tableadapter.For updating the combobox I have added code into the leave event. This does indeed update the client table as required. However, the id stored in the quotes table is -1. How do I make sure that the correct id is stored that references the newly added client record. For your information, the client table only has an id and clientname column.
The code is as follows:
[CODE] Private Sub ClientComboBox_Leave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ClientComboBox.Leave
Dim con As New OleDb.OleDbConnection
Dim dsClients As New DataSet

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 ?

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.

I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.

With VB.NET, I'm able to completely unzip a file - this is easy. I'm able to manipulate the resulting folders - again, easy. However, for some reason, I cannot figure out how to zip and entire folder. I can zip specific files, but I need a function that will allow me to input a path and then it will zip that entire folder, including the subdirectories

When someone saves record in the Register product table, items should be added into the combobox into Sell product table.

A little background... I'm trying to build a spell checking form. I have this lovely library: [URL] and it seems to be working flawlessly.
The problem I have is trying to replace an entire word and only the first occurence of the word.
Example: Replace the first instance of "foo" with "bar" in the following string
"foo foo foobar" and get this "bar foo foobar"
I've been trying regular expressions with no luck. Here are the patterns I've tried compiling(these are obviously tied to variables in my program):
"(?<!foo)foo"
"(foo){1}"
I also tried the built in string.replace method with a count parameter, but I have no idea how I would make that match the entire word.

I'm using a TabControl and have overridden the DrawItem event to produce my own background and foreground colors for the header text. It looks good but there's still grey color around each header. I thought maybe the Padding property could be set to (0,0) but that seemed to have no effect.

Fairly new to the VB.NET world, but a long time Access and FoxPro programmer.I'm trying to do something that was extremely easy in Access, but can't believe it is this difficult in VB.NET.I populated a combobox with values from a mySQL table. I want to return a hidden value from the combobox (Username), but the values that are being displayed are the full names (Firstname and Lastname). So the user selects the full name, but never sees the Username.
I've searched many different sites, and have seen examples that involve creating classes, and other complicated ways of doing it.This site explains what I am trying to do, where you select a City Name from the combobox, and it returns the zipcode. [URL].. However, the ValueMember/SelectedValue doesn't seem to work for me, or I am not understanding how it is used.or even a link showing my how this is done? I am just not finding the right info on my own.
