I do not know how to setup a loop for several pictures and displaying them in a picturebox by hitting a next button or previous button. I have two picture boxes on my form, I have a previous and next button on the bottom of the form, then I just need to know how to setup my loop for cycling through each picture. I have several pictures to go through.
View 1 RepliesIm using a black n white image of a human as my back ground and panels to display the same bits in color when the area is clicked. What isn't working for me is the panels are slightly overlapped and one will always be on top of the other. it is transparent so you can see the back ground, but not the panel underneath it when it has a picture in it.

I've been attempting to tinker around with connecting a MS access database to a vb 2008 app. I've successfully connected and can access the data by using the add data sources tab. But what I'm trying to do is create a form that has a (1) single line text box, (1) button, and (1)multi line text box. I enter a name in the single line text box, click the button(search db), and when the info is found, it is displayed in the multi-line text box.

I am using a webbrowser control, which is used for both internet and folder exploring. How can I determine when viewing files on the local directory, which file is selected?
I ran across something in my searches saying there was a property under the webbrowser.document called SelectedItem. But this must not be in 2008.
I am trying to move from the old ADO to the new ADO .NET . However , no matter how many tutorials I read over the internet , I still can't find a way to do something which , as I believe , has to be very simple I tried to mimic the way the graphic control did but I am missing some things ... I noticed that , in the graphic way , the wizard created 4 controls :- a DataGridView control- a DataSet control- a BindingSource control- a TableAdapter controlI recreated all of them and filled their correspondent properties , but yet I can't make it work . I think what I am missing is the connection itself . I looked on the internet and I think a connection can be made and opened like this :
Dim DataBaseConnectionMY As New OleDb.OleDbConnection
DataBaseConnectionMY.ConnectionString = "PROVIDER=Microsoft.Jet.OLEDB.4.0;Data Source = C:ProsoData.mdb"

1. I type the first letter of the username i want in the combobox text area, the combobox drops down and shows me all the usernames starting with that letter. I scroll down to the name i want (as i scroll down, the text area holds each name but the SelectedIndexChanged event does not fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
2. I do the same as above, but instead of hitting Tab key, i hit the Enter key. The same thing happens and i get the result i want.
3. This time, i first click on the dropdown arrow of the combobox such that it shows all usernames starting from the first name. I then type the first letter of the name i want. I saw that another drop down appeared in front of the first one and it was a smaller subset of names starting with the typed letter. I scroll down this smaller dropdown to the name i want (here also, as i scroll down, the text area holds each name, and the SIC event doesnt fire each time), then hit the Tab key, the SIC event fires and i get the result i want.
4. I do the same as #3, but this time i hit the Enter key instead of Tab key. But this time, the combobox text blanks out and the SIC event is not fired (although the name showed up just before i hit the Enter key). So i do not get any results back.
Is it pausible to get pictures in a menustrip? If yes, how?
View 4 RepliesI can do the basics when I put controls on a form but this one is a little more complex. I have an application that reads in a .TSV and populates a form with controls based on the number of objects it "reads." So for instance: I have a file that contains 10 people objects and my code populates a form with controls for each person. Easy stuff..Now lets say I have a ComboBox with the items: "Alive", "Deceased", "Unborn". Right next to this I have a textbox for age. Now originally, this textbox is not enabled because the default value for the ComboBox is "Unborn". But lets say when the user selects "Alive", I want that textbox to become enabled so an age can be entered.Obviously from me asking this and the title of this question, I don't know how to go about doing this. I don't really understand events and I learn by example but the MSDN examples don't quite cut it.
