Passing File To ComboBox?
Sep 1, 2009
I am new to VB environment. I am using Visual Studio 2005.In certain code, I need to add 4000 elements to the ComboBox list.
Using the command
ComboBox1.Items.Add()
seems ridiculous.
I am thinking of creating EXCEL File, in which I will put all the names in 1 column and call that excel File, when "dropdown" of combo box is clicked. how this will happen?? code related to this? or if this issue has already been discussed then plz give me the link for the same If this is not good idea like putting 4000 elements, then can there be any other solution?

i have a very simple problem but i can't figure how to fix it.I'll explain, i have 3 array named "Auto, Legumes, Films". I i making a function so whenever the selecteditem of the combobox change(Auto, Legumes or Films) the name of the selecteditem is passed to a function. The function use this name to display the items of the corresponding table in a listbox.The 3 different item name in the combobox match the name of the 3 tables, so i want to be able to re-use the name dynamically in my function.
Code where i call the function:
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbchoix.SelectedIndexChanged
[code].....

The case is that I have two comboboxes (country and state) and a simple code to populate the state combobox accordingly depending on the selected country. Ok this is simple and easy, and this code is within the country combo change event.The case is that I have more than one pairs of those comboboxes and I wouldnt like to repeat all the populate code into every country combo change event.Actually I would like to have only one function and just call it passing as parameter a reference to the combobox I want to populate. Then I could use that reference into the function.

I have one problem solved, properly converting text to numbers. Now I want to use that conversion as a selection parameter in a FillBy statement.I have two comboboxes linked to an Access 2007 database. One box lists the names of the States in the US. This is what I used for the Table Adapter Configuration Wizard for the combobox "State". [code] ST_UID is an Integer. I created a label with a bound value to STATE.ST_UID so that when a user selects the name of a state from the State box the appropriate ST_UID populates the label, (i.e, California has an ST_UID = 5). The problem is when a state is selected, I only want the Counties for that state to appear in the County box, i.e, COUNTY.ST_UID = 5 if California is the selected state. [code] Problem is I'm not getting any results, the "County" combobox is blank. I've tried a lot of variations on the code, such as % StUID %, etc., but no luck. I have experience with VB 6 but am a beginner with .NET.

I have this in VB6

It works just fine if I use pctrlListBox As ListBox or if I use pctrlCombo As ComboBox, but I need to be able to use both with the same routine.
(PS: Yes, I do have a leap year check in here which I took out as it is not germine to my translation problem.)
(PPS: Using a control such as the monthview or datepicker is not an option.)

[code]This works fine and passes 8 parameters into the sysimp.bat file. The problem is if I try to pass in a value that has a space between the text then it will treat it as two parameters rater than one.So if P1 value is for example "Hello World" then when passed into the bat file it will assign "Hello" to P1 & "World" to P2. Is there a way to wrap the text in the parameters or should this be done in the .bat file?

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.

I can understand since .ini files are pretty outdated, but I'll explain. I have a combo box, and inside the combobox I want it to display the names in a section of the .ini file. So say my .ini file contains the following:
[SECTION1]
Name = Billy
Lastname = Bob
Inside the combobox I wan't it to display the items "Name ", and "Lastname " only, not the section or the values.

I am trying to fill a combobox with data from an xml file. I have it setup on form load to call a loadXMLdata function. In the loadXMLdata function it reads the xml file. I would like to know how I would return each of the elements to populate the combobox. I have mostly done php work and in php i could do an array like this: array[book] = "VB.Net Programming". Is there a way to do something like this with an array such as xmlData("Server 1") = "255.255.255.255"
HTML
<config>
<connection>
<servers>
