View 1 RepliesI have one listbox an import button and a save button. Basically the import button allows the user to select photos and he list box then shows the directory for them. Is there a way to save the image that has been selected to a different place? whilst at he same time changeing the file name.e.g. the list box would have the directory like this "c:documentspicturesimage1.jpg" I would then like to save this file like such "c:desktop est103.jpg"
View 1 RepliesI have 13 variables, all called Items1, Items2, Items3 and so on. I have a combo box with items in, each time I click a button I want it so whatever is selected is stored in a variable and if the button is selected again then it stores whatever is selected in the next variable. I know all the code for selecting items in a combo box and transferring it to a variable but the problem I cannot do is the part where each time a button is clicked it stores whatever is selected in the combo box to the next variable.
View 9 RepliesI have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.
This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure

De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.
That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?

How would you get the text from the currently selected item in a listview?
View 2 Repliesthis seems like such a stupid question but I've taken a long while off from coding and have forgotten how to call up the text from the selected item in a listview. This is because there is no '.text' function within the listview. I looked all over the internet but found 0 solutions . Everything I found just didn't quite answer the question. I have to assume that someone on here would know.

If Radio1.Checked Then

View 3 RepliesWell, the question says it all. I have tried the _.SelectedItems(0) method, but it is not working at all. It only works for the first item, but for all others it says that "0" is not a permissible index value, or something like that.NOTE: All of my items are constant, as in they will not change. None will be added, and none will be removed.

I have a GridView with image buttons for selecting rows. I am using an OnRowDataBound event to color selected rows Blue:
e.Row.ForeColor = System.Drawing.Color.Blue
Now that works great as long as I don't set a color either in the CSS stylesheet or on the grid Items themselves. If I do that, then all rows are colored that color and I don't get my Blue selected rows color for selected rows. I would like to color the text in the grid something other than black.
a dialogue box to have the user open a file they wish. I'm trying to open a specific file when a listbox item is selected and I have that down but I'm running into the problem of needing to have "" in the display which is impossible from what I can tell in the code. I just need to know what goes in the quotes which will open the file. Also lets say the text file was 'supportdoc1.rtf' and was located in a folder inside of the program folder called 'SupportDocuments' would the path be "SupportDocumentssupportdoc1.rtf" [Code]

View 3 RepliesI'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.
What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:

I am making a password program that remembers what the password is for and what the password is. I have two listboxes: 'listbox1' for what the password is for, and 'listbox2' for the password. I also have a remove button. I would like it so when you press the remove button, the selected item in listbox1 is removed and the password in listbox2 is also deleted. The passwords are stored in two settings: what, and pw. The items that will be deleted will have the same value. By value i mean they will be the same number item. E.G. the 1st item, or the 3rd item in the list.
