Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

I would like to know if the .NET framework gives you a way to retrive the littles thumbnails Windows XP+ generates when you alt+tab. The application I try to make should be able to get a window capture (ALT+PrtScr) of another Window that is not necessary Active and could be partially or completly hidden behind another one. I tried the codes found there [URL] altprintscreen with no success in the case the window I'm trying to capture is not visible.

I am trying to click on certain rows in a datagridview and have the information in the rows sent to a textbox. It does not append each row to the textbox though, which is what I want it to do. it just replaces it with the row I click on. What's wrong with my code. I have tried cell click too.

I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
So this is what I got.
Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"
[code]....
It only adds the first rows details to the text box when I click the second record the first rows details are still there.

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

have made a connection to a database through VB and i was able to extract a single value from a record and display it in a datagrid table, but i don't know how to display that value in a textbox. i tried doing e.g. txtABC.text = datagrid123.item but it seems that the values cannot be converted between the datagrid and the textbox.

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

Ok, I have been going around and around with this for hours (Searching, etc). This is what I want to do, I want to load data into a Text Box and if the user changes the text in the Text Box I want to be able to save the new text.
My problem in the TxtBox_TextChanged event the data contained in the txtNarrative Text box is the new data that the user typed in (<>ABCD) but in the btnSubmit_Click event the data contained in txtNarrative is the original value ABCD.

I'm working on a project that will compare two textboxes and output the difference in a third textbox. To provide some background what I'm trying to do is compare a users active directory groups to another users groups. What I want this program to output is the groups the user already has, groups that need to be added, groups that need to be removed(basically unique values).comparing text will output an integer, or boolean. I need the actual difference outputted in text to have a working document of changes to groups.
Here is an example of what I want it do, but i'm only able to get it working using an excel macro.
Sub UniqueValues()
Application.ScreenUpdating = False

I have some textboxes that I need to get data to on another tab, everything works beautifully until I get to one and that is where the client ID has to be filled oin to that textbox. I have a chkBox that will verify the data that is suppose to be put over intothe tabbed page and if I check it, it will put the data into the textbox. Yet if I leave it unchecked the data does not get copied.
