Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If (ComboBox1.SelectedItem = "RPG") Then

I am trying to load an Excel 97 single tabbed spreadsheet into a SQL server table using the OleDbDataAdapter function. From all the documentation I have found, the first parameter should be "select * from [sheet1$]". This works fine for me only if the tab in the worksheet is named Sheet1. If I change what's in the [] brackets to the actual tab name, it also works fine.

I have a Customer File, and want to serach through the customer file to find a customer. I want to be able to Load the data into an array, and then from that array into the list view. BUT i don't want all of the feilds. I only want 3 (out of a total of 7), CUST ID, FNAME, Lname, etc. When the user clicks on the searched Customer, it then displays that customer in the form.
What I am not sure about doing is loading the file into an array
Edit: The file is a .dat file. I will happily attached my form if someone requires it
EDIT2: Can't count to 7

Im trying to load a price of an item from a prices file (Items). The variable (ItemName) is taken from a listox populated from the file on another form. And (Item) is the structure which i saved the prices information for into (Items).
What im trying to do is take the string from the listbox and change the textbox (txtCurrentPrice) text into the price for the highlighted item, which is also the name of the (txtItem) textbox.
However i cant find a way to reference the Item.(ItemName) to get the correct price from within the file, as ItemName isnt a member of the Items structure Item instance.
ChangeItemForm
Private Sub ChangeItemForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
ItemName holds the name of one of the variables saved in the structure. So say if ItemName was holding "IridescentRoll" As its string I would be trying to find Item.IridescentRoll, which would show me the price of IridescentRoll which im trying to put into the textbox. and As Item.IridescentRoll = 3.35 it would display 3.35 in the textbox.
As you have probably guessed, the Item.ItemName doesnt work ('ItemName is not a member of...'
Is there any way to write this without having to create a new record for each item? As that would take a while, and im not sure i have the time x.X

visual basic 2008
I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)

I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
The text file looks like this
Test.txt
John, Doe, 40, 12/04/1968
Micke, Gulm, 39, 07/08/1970
[Code].....
sort out this issue as I need read the entire text file which in reality will be about 5000-10000 lines and insert them in to the SQL DB line by line.

Is it possible to load an *.ico file onto a PictureBox ? I know I can use : PictureBox1.Image = System.Drawing.Image.FromFile("C:MyImage.jpg") but I'd like to use an icon . I have tried some other methods that read "Icon" , but I failed . Up to now the only thing I have thought is converting the file format form *.ico to *.jpg , but I think that's ridiculous ...

I've written the following sub to load a comma delimited file into my datagrid view but it's hanging up when it attempts to load the first two values into the cells of the datagridview. I think it's having trouble adding the cells to the datagrid. I have tried writting them directly using the .text of the specific row and cell but when I incremented to the next row it hung up because the row didn't exist (I think).

I have an application that reads data values (numeric) from a data file. Due to a change in data requirements, I need to put these into a paramArray so I can calculate the MEDIAN of the series of numbers. I have seen some of the MSDN examples and they are all good except they load the paramArray with ArrayName(#, #, #, #, #). That's OK for a simple example, but how do I load a paramArray while reading numeric data from an ASCII input file? The number (Ubound) of samples is usually 153 but can vary considerably.
I think I can work out the rest of the MEDIAN calculation from the MSDN example code.

I have been searching for days to get some code that will do this. I need to open a spreadsheet and read maybe 2 dozen cells into variables in a VB.Net program. Specifics are: MS Office 2003, Vis Basic of VB.Net 2008. Everything seems to revolve around the following lines which do not work for me. I am not sure if this is version differences as most ppl here do not name which version they are using. [code]Does this method not work in VB.NET 2008?

I generate my xml into "variable string str" by using "dataset.GetXml" and then I write the "xml which is contained in variable str" into "file.xml" by using sFile.WriteLine(str) while 'sFile' is a stream reader"My reason for using 'writeline' instead of 'dataset.WriteXml' because I need to encrypt the 'xml stored in 'str' before I store it into file.xml.I got everything fine for the encrypted result, and so does the decrypted result as well.Here's the decrypted result of my file.xml below (I have checked it the xml value which in str before encryption and which in decrypted file.xml. They are all match well)Here is my plain xml value before it got encrypted or decrypted which I stored it in variable str by using GetXml. I don't know for sure but my xml value doesn't contain declaration "<?xml version="1.0" encoding="utf-8" standalone="yes" ?>" like common xml used to have.All the xml file which I got from GetXml is just like below (No declaration like <?xml version="1.0" encoding="utf-8" bla ?>) Book 1 2010-09-22T14:43:00.0000000+07:00
And since I think it may not cause any problem then I keep coding and decrypt it which is going well and the decrypted result is perfectly same ofcourse.My problem is, when I try to make my xml value show in Data GridView by using the code below, and run the debug, it prompt an error said "could not find the file c:laFile.xml ".
ds = New DataSet
path = System.IO.Path.GetFullPath(strFileToDecrypt)
ds.ReadXml(path)
