VS 2008 Load Combobox With Database Values?
Jun 5, 2009I would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.

Load Large CSV File Into Database?
Oct 14, 2009I'm trying to load a large CSV file into a Microsoft SQL Server Compact 3.5 database. I've tried using the following: Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser("filename.txt") MyReader.TextFieldType = FileIO.FieldType.Delimited MyReader.SetDelimiters(",")Then splitting the data with MyReader.ReadFields() etc, before using this data to add rows to a dataset in a database table in my project. However, my CSV files are very large, at above 9.5 million rows, and this takes forever, if the computer doesn't crash also. Does anyone have a better idea for what to do? I would like the CSV file to be loaded into the database table, to enable me to sort it, and undertake some querys and maths. The CSV data structure is:2,193,761.40000000000012,43,1510.22,8,1929.60000000000012,22,2564.52,22,2791.70000000000032,19,2971.6000000000004

Large Database File (mdb) Takes Time To Load In .net So Alternative?
Feb 8, 2011I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large
So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?

View 1 RepliesLoad Two XML Files Into Combobox And TextBox?
Jul 17, 2011I have a problem when trying to show details of XML file by choosing an item from Combobox. I have two XML files, called Employee.XML & Subject.XML. The format is like below
<Employee>
<EmployeeID> </EmployeeID>
<Position> </Position>
[code]....
The Combobox contains Employee and its Position also (eg: A1 - IT professor). When I choose an item in here, its Subject details will automatically show in Textbox (one EmployeeID can have many subjects). I cannot use Combobox.SelectItem because I already set Option Explicit On & Option Strict On. I also make EmployeeID by ascending coming up with its position. How can I show details in TextBox by using Subject.XML? I tried many methods but none can work properly.

VS 2008 - How To Load Text In ComboBox
Oct 5, 2009I want to make it so you can type a name into an input box and have it go into your combobox1. Then also have it to where you can load a list of names into your combobox from a text file where the text in the text file would be like this
NAME 1
NAME 2

So it will enter in the combobox1 like that. Also, This is an account maker, So I was wondering how I would make it so after it creates the account it will use the next text, can I just use the "Next" method?

C# - Dynamic ComboBox Datasource Form Load
Oct 21, 2010I'm creating a dynamic combo box and adding to a form. I'm trying to fill the combo box with a DataSource from an ArrayList and then selecting an item in the combo box based off a value from a property.Problem is, the combo box items don't get bound until after the Form_Load event has finished and the form is visible. So the combo box is empty when I try to set the selected index of the combo box. See code for what I'm doing in detail, and refer to comments in

How to select the right selected index for combo box without a hack (Load timer or something stupid like that)?
Load Combobox Items Dynamically On KeyPress?
Oct 4, 2010I want to create a combobox like winform control in VB.Net that makes suggestions dynamically; exactly as the address bar does in Google Chrome or IE 8/9. Basically on each keypress, get a list of items that match the entered text on a background thread(s) and show these items in the dropdown list as they are (possibly slowly) returned - either from DB queries, web services etc.
I have tried a couple of ideas, changing the AutoComplete list dynamically or binding to a list, which I then update. But I am getting some rather odd and incorrect results even when updating the list directly (on the main thread). I also tried implementing my own textbox control that shows a ListBox control where the dropdown would appear - this seemed a lot more reliable but I cannot get it to draw over the edge of forms etc when shown, as the combobox drop-down does.
