Well here is my problem, I have an XML file and from there I have data going into a drop down ComboBox, what I need is the data from the next column over that corisponds to the same row, ie. the phone # that corisponds to a person's name in a data table.I semi-know what I need to do I just can't figure out the code to take the index of the ComboBox and take the data into the Label.
View 4 RepliesI have a combobox which reads a directory and displays the file names in the combobox. What I'm trying to do is when a value is selected in the combobox I wish to display this in a label.
I have tried the following
Label1.Text = Combobox1.SelectedValue
But it doesn't seem to work.

I am successfully hiding a combobox, based on the selection of another combobox. However, I can not get the label of the combobox to hide as well. The code I am using, which is basically the same code for hiding the combobox itself returns the following error:
Error 1 'DOCUMENT_EVALLabel' is not a member of 'WindowsApplication1.Form1'
Here is the code I am using for the label:
Me.DOCUMENT_EVALLabel.Visible = (EVALUATIONComboBox.Text = "Text")

View 1 RepliesI have 2 forms. The first form has a label on it. The second form has a combo box, a text box, and a button on it. In the second form, when I select the label name that I want to edit, I type in what I want to change the label name to in the textbox and I click the button. Now this goes through flawlessly except I want the combobox item to change to the NEW label name. I've been able to do that but when I close the form in run-time and open it up again, the previous label name appears once again. Is it possible to make the combobox add the new label name and KEEP it in its collection?

View 1 RepliesI'm using Visual Basic 2008 Express Edition, so I have a combobox that gets filled with items from a data base made with Microsoft Acces, the combobox is filled with the values stored in a column from a table in de database so the user can select an "option" from it, I want to add labels that show the values for the corresponding row of that column. I used the Data Source panel to drag and drop the labels corresponding to the values that I want and it works it show the value that I want when I compile the application (at least I think it does, it could be that it's only selecting the first entry) the problem is that when I select a diferent entry on the combobox the labels don't refresh with the new values. How can I do that?
edit
how does Visual Basic Populates de combobox and gets the value of the other Acces DB entrys to change the .text value of the labels? And I mean the actual code that does that.

View 7 RepliesThis question is a follow up to an earlier question I had that was quickly resolved. The previous question can be found here: Selecting TOP 4 records from multiple SQL Server tables. Using vb.net..I selected the top 4 rows from multiple SQL tables ordered by date. How would I then go about placing that data into labels. There should be 16 items in total (4 columns, 4 rows). However if I try to use sqldatareader I only get items 0-3 and anything more is outside of the array. Should I not be using an IF statement in this case? In addition to the newly formed select statement based on the previously linked question, here is what I have: [code]

I'm doing a project that requires me to create a book ordering form. I have the books displayed in a listbox named bookselectionlistbox, and when a book is selected, it displays the price of that book in a label named bookpricelabel1. I have a button named addbutton that allows the user to add the book to the shopping cart. The shopping cart is in the form of a combobox named shoppingcartcombobox. Lastly, there is a receipt button that transfers ALL the books from the shopping cart to a seperate label called label3, not just the selected book. The last thing I need to do is have the price of each book also transfer to the receipt section. This needs to be done either on the same label3 on the same line as the book title, or on a seperate label that is adjacent to label3, I have temporarily placed a label there named label5. I am using a case statement for the bookselectionlistbox to say that when a certain book is selected, the bookpricelabel1 will display "$xx". I also have an IF statement under the addbutton label that generates a total price for all the books in the shopping cart, here is an example of the code I used for one of the books:
[Dim visualbasic As Decimal]
[If shoppingcartComboBox.Items.Contains("Visual Basic") Then]
[visualbasic = 55]

I have Data coming in through a serial port and it consists of pretty much all numerical values except for a few begining response characters. Its a Load Cell which spits out Tension in Pounds. I'm making a simple terminal program with the ability to log the Incoming Data for record keeping and data plotting. I want the incoming Tension to be displayed on the screen real time.I can get it into a text box and have it scroll indefinetly as it updates the data,but I'd like to keep it localized in one Label. I can display it in the Label but it wants to scroll down as it comes in. I want to keep it refreshed in one spot if that makes any sense. Heres what I have thus far. It will put it in the Label but wants to scroll like in the textbox. For example if I send #00F0 followed by a carriage return it replys back with whatever is displayed on the Screen which usually is the tension.it says "01TK 00.074 LBS" no quotes.. for a reply.I'm assuming it needs to be stripped down to just the numeric characters first.'here is what gets sent to the Load Cell to tell it to output data fast as it can to the serial port.[code]

I'm doing a project for my vb.net class and I'm running into an issue figuring one part of it out. The way it works is the user selects the name of a book from a list box and then clicks add and then it's added to the shopping cart which is a combo box. Then there is a receipt button and when that button is pressed, it makes a groupbox become visible and in that groupbox there is a label and I need that label to display ALL of the contents of the shopping cart combo box. I know how to transfer the selected combo box item to the label but how to transfer ALL of the combo box items to the label.
The name of the shopping cart combo box is "shoppingcartcombobox"
The name of the add button is "addbutton"
The name of the label is "label3"
