To run this you'll need a combo box, and an excel spreadsheet added to your desktop. Of course you'll need to change the path to the spreadsheet to whatever you choose. After doing so, I get an error that I don't really understand.

im trying to pick up Visual basic on my own with no friends/family that have any programming experience.. I'm struggling (surprise surprise)Heres what I'm trying to do...I have 1 combo box, It will list product names.. Lets say 15 of them.. (I know 15 i could just as easily specify them individually within VB.. but lets assume I NEED to read them from an excel file.(Excel 2003)
Part 1 :Really all i need to know for now, is how do I load an excel worksheet into VB so I can call data up from the cells / rows / columns..
Part 2 : How do I define Which Cells from Each row or column I want to populate into the combo box... Presuming for the "Product name" combobox I have placed each of the 15 product names in the excel file under Row 1, column A through Row 15 , Column A.I want to avoid this and just call the xls file into VB. (Excel will be installed on any computer running this application if that matters. )

I'm creating a reporting web page as part of a standard VB.NET web application. The page is data driven, with jquery making calls to a web service local to the application to get values of elements that are dynamically created in the DOM. Ultimately these dynamic elements and their values are all wrapped up in a JSON object, so that part of the client side is fine.
Right now, I can pass that JSON object to a method in the web service which creates an SQL Data adapter from the values and queries a database. My ultimate goal is to have this client JSON data be used to query the database and construct an excel file to send back to the user, or failing that a CSV file.
It's my understanding (from working with PDF file generation) that this type of function can only be done on the server side of the web application, not even from the web service (i.e. I can't have the web service return an array of bytes and have JavaScript/jQuery present that as a file).
So, how do I go about this? Now I have my JSON object on the client side, where should I be sending it, how, and how do I go about returning my file?
I've read about either storing the JSON in a hidden field and having the server take the elements value and go from there, or using AJAX to send the JSON to the server just before a postback is made to fire off the server-side function to run the query and return the data.
I just need a little guidance, and a little help understanding where to use the hidden field, or what I am actually doing with the pre-postback AJAX call.

Novice VB user, trying to create a pop up msgbox upon opening a file, whereby the user selects from a list (of available options), the choice then gets entered directly into a cell reference. I have seen this before and know that it's primitive programming but i'm still a learner.

I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

I have a combo box with a data source. This box shows one column of a table and allows me to select one item.Next, I have an ordinary text LABEL that I need to put text from another column of the item selected above.I tried to set the data binding field of the label, but this grabs only the first row or data and shows the selected column. That is nice, but I can not figure out how to update the selected selected ROW when the combo box item is changed.In this case the combo box lists a bunch of inventory parts. When I select a specific part, I need the change the text in a label to show the manufacturer. (like a sub-form). This same behavior will be used in several other places, but the relationships can cascade.

I am trying to read excel data (Excel 2007 SP1, on Windows XP SP3) with visual basic .net 2008 (VB 9.0 SP1). I have tried several attempts and whatever I do I am getting the following error message: System.Runtime.InteropServices.COMException was unhandled ErrorCode=-2147319784 Message="Altes Format oder ungültige Typbibliothek. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))" Source="Microsoft.Office.Interop.Excel" Message="Altes Format oder ungültige Typbibliothek." Translated: Old format or unknown type libraryI have added the reference "Microsoft Excel 12.0 Object Library" to my project. I am assuming that I might have to add a different or an additional reference, but I do not have any clue which one to use. List of things I have already done:- Searched other forums- Altered the language settings- Tried it on an other Computer (Win XP SP3, Excel 2007, Visual Basic 2008 Express)- Ran the diagnostics tool in Excel - Updated all updates etc...- Reinstalled Visual BasicI really do not have any clue why it should not work?

I created a VBA project in Excel. I would like to figure out how to transfer the data back in forth to make a more presentable and user-friendly program in VB Studio.Basically, I need my form in VB to input data to into an excel �workbook.data�, where the calculations are preformed. Then I need to copy the finished excel data cells �workbook.results� and paste them into an end result form in VB. I have tried looking at threads and cannot come up with a solution. There is no data saved each time the program runs, so I don't have a database.

I have written a class library that creates a dll to pass data back and forth within the same compiled instance exe. Is it possble to configure this Class Library in order to pass the data produced in the first instance of an .exe to other instances exe programs written in VB.NET?
My first thought was to add a Module. Older versions used Declare Files. Is there something in the compiler that I should set where the variables point to a specific memory address, or something..., that makes the variable available to other VB programs running in a seperate instance?

I have 2 forms. Using Visual Basic.On Form 1 there is a populated combo box. This was done so by running a query through it and populating it with PUZ_ID values from a data set.On form two there is a tool strip and below is a search query.I need to be able to select the value i want in the combo box on form 1, and launch a button that opens form 2, which has loaded the data that i binded onto the form.Anyone have any ideas/code or need me to clear this up a bit more?So i need to run something through a query, or make something public or what?

I would like to have custom methods to pass data between function, or to keep it in memory throughout the program.
Example:
Private function info()
Addr1 = addr1.text
Addr2 = addr2.text
City = city.text
[code]....
Could I run this function towards the beginning of the program and use it throughout until the form is disposed? I can't seem to get the information to stick once I get out of the function, I will need to use the same information multiple times throughout the application so I figured if I could make a function to keep the info rather than declaring the 5 lines in every option but anytime I call the method, it fills it correctly then when I get back to the main function the info goes back to 'nothing'. is it possible to pass data around between functions like you could in Java?
