View 5 RepliesVS2010 Populate ComboBox From Text File?
Mar 31, 2012I have created a simple conversion program, I have two comboBoxes that are populated by a text file called 'data.txt'. It all works perfectly apart from when i have the squared units in it, instead of getting the '�' symbol that is in the text file, i get a diamond shape with a question mark inside.
I would think that you must have to put some sort of code before the squared symbol in the text file, but I cannot figure it out.

Populate ComboBox With Comma Separated Values From INI File
Mar 27, 2012I'm attempting to add comma delimited values to a combobox. The problem is I do not know if this is the best way to split the values into the combobox. Is there a more cleaner/efficient way to do this?:
Dim toread As String
toread = ini.ReadValue("Schools", "Schools")
Dim textdelimiter As String
textdelimiter = ","
Dim splitout = Split(toread, textdelimiter)
Dim i As Integer
For i = 0 To UBound(splitout)
ComboBox1.Items.Add(splitout(i))

Jul 29, 2011I have two ComboBoxes
<ComboBox Name="cmbMake" DisplayMemberPath="MakeName" SelectedValuePath="MakeID"/>

Populate Combobox From Selection Of Another Combobox?
Jan 1, 2012I currently have a form with two comboxes. The first cbo is being populated with a project number, which is being pulled from the first column of a spreadsheet. I now want the second cbo to read the first cbo and then find that project number on the spreadsheet; when it finds that project number, I then need it to copy data from the row the project number is on. I have converted to vb from vba. Below is the code I used in vba (which obviously does not work). I only need certain cells from the project row.
Dim proj_num, rng As Range
Dim data, i As Long, j As Long
