VS 2008 - Textbox And Combo Box - User Has To Only Put The Icao Code And It Will Display The Airport
Mar 22, 2010I have a ton of airports listed in my Combo Box Right? They are displayed in the following format;
Airport Name (ICAO Code)
For Example
Kansas City Intl (KCI);
Since I have so many, Can someone provide me with a code i can use so in a textbox the user has to only put the icao code and it will display the airport.
For example
TextBox1.Text = KCI
Once that user has clicked out of the text box, It will seach the combo box for any values with KCI and will display it
So if textbox1.text = KCI, then combobox1.value = Kansas City Intl (KCI)

View 1 RepliesOpen Excel File And Reusing Existing Excel Instance?
Jul 13, 2010I have an application the contains several excel files bundled with it. I'm not opening the files and processing them within my application. These files contain a data-connection to reload all of the pivot-tables within each excel file. I have a 'link' on my form, that when clicked, it determines which file to open and calls a sub using filename and executing Process.Start(filename) for any excel file I want to open. I have no problems opening any one of the files and then exiting excel.
The problem is when I 'close' a file, but don't exit Excel; then try to open another file(clicking link on form)... it creates a new instance of Excel.
I know from experimenting that the fileopendialog form will 'reuse' an existing Excel instance, IF it does not already have a file open.
How can I do the same thing without using the fileopendialog?
I don't want the end-user to have access to the folders where these files live. That's why I have multiple 'links' on my form, one for each xls that already exists. I just want them to be able to click on a link and the xls file opens AND if they choose to merely 'close' a file and not exit... Don't create a new instance of Excel, but re-use the existing one.
