View 3 RepliesComboBox Populated And Displayed With Multiple Columns
Nov 8, 2010I have seen something like the following in many software. Combo box populated and displayed with multiple columns (for example stock code, stock description). But now I am only able to populate with stock code. May I know how to achieve this? I know it can be done by calling a form (And I can do whatever coding in this form) out when clicking on the combo box. But I am looking for better solution, or is it possible to populate the whole datagrid into the combo box as source instead of only the data.

Add To A Combobox A List Of Item (not Every Item) In A Txt Located On A Server
Feb 13, 2011my program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)
Change List Of Combobox A Based On Item Chosen From Combobox B?
Jun 17, 2011I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

Position Of CurrencyManager Not Changing?
Apr 2, 2011I'm starting to learn about using the CurrencyManager to change the position of data and seem to be missing something because the postion is not changing. look at this code and let me know what I'm missing?
I hard coded the postion in:objCurrencyManager.Position = 1 and used the debugger to step through the code to see what .Position is holding and after the statement executes, the value is still 0 even though there is data in the dataset. I was hoping the textbox would display the data from the dataset located in the 2nd row of the dataset but the position never changed.

VS 2005 CurrencyManager.Position += 0 ?
Dec 17, 2009what the purpose of the following code is:[code]....
What it does appears obvious: it increments the position by 0 (i.e. leaves it unchanged) so it appears that it does nothing-but the vendor included it so I'm assuming there's a reason.From the comments, MyCurrencyMgr is the CurrencyManager for the 'primary table' and the CurrencyMgrCollection should contain CurrencyManagers for 'other tables' but I can't find where any are actually added to it-and whether the other CurrencyManagers exist or not, I still can't see what the purpose of this code is.
Read Individual Lines Of A CSV File Into A String Array, To Then Be Selectively Displayed Via Combobox? Input?
Apr 2, 2010I've got myself a CSV file with the following contents:
1,The Compact,1.8GHz,1024MB,160GB,440
2,The Medium,2.4GHz,1024MB,180GB,500
3,The Workhorse,2.4GHz,2048MB,220GB,650
It's a list of computer systems, basically, that the user can purchase.I need to read this file, line-by-line, into an array. Let's call this array csvline().The first line of the text file would stored in csvline(0). Line two would be stored in csvline(1). And so on. (I've started with zero because that's where VB starts its arrays). A drop-down list would then enable the user to select 1, 2 or 3 (or however many lines/systems are stored in the file). Upon selecting a number - say, 1 - csvline(0) would be displayed inside a textbox (textbox1, let's say). If 2 was selected, csvline(1) would be displayed, and so on.
It's not the formatting I need help with, though; that's the easy part. I just need someone to help teach me how to read a CSV file line-by-line, putting each line into a string array - csvlines(count) - then increment count by one so that the next line is read into another slot.So far, I've been able to paste the numbers of each system into an combobox:
Using csvfileparser As New Microsoft.VisualBasic.FileIO.TextFieldParser _
("F:folderprogramnameprogramnameinDebugsystems.csv")
Dim csvalue As String()[code]......
But this only selects individual values. I need to figure out how selecting one of these numbers in the combobox can trigger textbox1 to be appended with just that line (I can handle the formatting, using the string.format stuff). If I try to do this using csvalue = csvtranslator.ReadLine , I get the following error message:
"Error 1 Value of type 'String' cannot be converted to '1-dimensional array of String'."
If I then put it as an array, ie: csvalue() = csvtranslator.ReadLine , I then get a different error message:"Error 1 Number of indices is less than the number of dimensions of the indexed array."

I have verified this by previewing the data in the dataset.My problem is getting the combobox to reflect the changes to datatable to which it is bound.[code]
