View 4 RepliesMultiple Listbox Selections?
Sep 18, 2011I have 2 listboxes, listbox1 holds File names, listbox2 holds fullpath of the files(listbox2 is hidden just to keep things looking tidy).
What i want to do is (using multiselection) is select files in listbox1 and have listbox2 have the same files(indexes) selected as well.
i am rather new to this but i have tried several ways but listbox2 only selects the first selected file from listbox1.I am using vs2010 visual basic & wpf?
Multiple Selections In Text Box?
Sep 23, 2011In a small app for demonstrating the use of Regular Expression matching in a text box, I have set it up so I can select one of the matches at a time in the text box to emphasise it. Is it possible to set up a text box so several isolated sections in the text is highlighted so all of the matches are highlighted at the same time. I'm thinking not and could use a picture box to do this but with all the hidden features in vb.net, I wanted to be sure since this would be very handy for my project and would be more useful for large amounts of text. I've read you can make multiple selections in the text box of a combo box.
View 4 RepliesVS 2005 ListBox Multiple Selections?
Oct 20, 2010Working with a couple of listboxes to display userid and emailaddress. I am writing an application for viewing SSRS reports instead of using the Report Manager. I am able to select the report and also send an email to users with a web link to SSRS report so that ReportViewer comes up for them to view, export or print the report. Currently I am only able to send to one recipient and I'd like to be able to send to multiple recipients. However I am having difficulty with the multi-select from a listbox. I have set the SelectionMethod to MultiExtended and so I can select multiple items from the listbox. Here is my code -
[Code]...
and I also add a messagebox.show to display my values, in EmailAddressTo variable, it displays "System.Data.DataRowView" so it was not able to capture the email address at all. Then if I debug further I eventually get the error msg - "The specified string is not in the form required for an e-mail address." because of the empty variable. Using SelectedValue, I was able to get at least the first email address but not the second one.
Testing On Multiple Selections Made In A Listbox?
Apr 5, 2011I am a new student of Visual Basic. I am using Vis. Studio 2010. Is there some sample VB code that I can gain access to that shows how to test on multiple selections that were selected within a listbox using the "For each" construct? In this scenario, multiple items have been selected but not 100% of them. I need to know how to test on which ones are selected as I examine each one in the list using the "For each" construct.

Preventing Duplicate Selections From Multiple Combo Boxes
Aug 6, 2009Ive got 10 comboboxes on my form, each of them have the same items. I'm trying to get so that if I pick something from the first combo box it doesnt show up in the list for the 2nd box, etc. Also, I didnt want to just remove the item, incase the user changes their selection in a previous combobox. [code] Rest of the comboboxes have that last piece of code, with the boxes and stuff changed to the correct ones.

I'm trying to get so that if I pick something from the first combo box it doesnt show up in the list for the 2nd box, etc. Also, I didnt want to just remove the item, incase the user changes their selection in a previous combobox.Example of the code I used, as im on a different computer right now.
Code:
Dim cboList As New List(Of String)
Dim index1, index2, index3, index4, index5, index6, index7, index8, index9 As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Rest of the comboboxes have that last piece of code, with the boxes and stuff changed to the correct ones.Problem is that it doesnt remove the previous selections correctly.
Replace Multiple Selections In Listbox With Textbox.text?
Oct 23, 2009I have code that works to place two items in listbox into two textboxes when selected (multiple select extended).
Private Sub lstOutput_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstOutput.SelectedIndexChanged
Dim i As Integer = lstOutput.SelectedIndex
[code]....
I need also to be able to modify the data in the textboxes and replace the lines in the listbox. The reverse code doesn't work properly, it only replaces the first selected item. The "lstOutput.Items(i + 1)" appears not to lead to the second selected item.
Dim i As Integer = lstOutput.SelectedIndex
lstOutput.SelectedItem = lstOutput.Items(i + 1)
lstOutput.Items(i) = txtName.Text
lstOutput.Items(i + 1) = txtPhone.Text
I have scoured the web for ways to manipulate the selected index/indices, with no success.

Multiple Text Boxes And Combo Box Selections Output To Txt File?
Nov 1, 2009I'm using Vb .net 2008
I could use some advice/examples to acheive the following:
I have 1 form, 4 text boxes, (textbox1 ,2, 3, 4)
Textbox1 and Text box 3 and single line text boxes.. Textbox2 is multiline.. (a description field which can be as long or short as the user desires..)
Textbox 4 is a large multi-line textbox that will contain the output of Textbox1,2,3.
I need to find out how to output the contents typed into Textbox1,2 and 3 into Textbox4 while maintaining formatting..
For example, contents of Textbox1 should always be the first text displayed in textbox4, immediately under that should be the contents of Textbox2, and under that, Textbox3
I want to ensure that the text is displayed in that order even if the user enters information into Textbox3 first.. and still displayed in the proper order if Textbox2 has 1 line of text or 20 lines of text.
How could I do this? How can I make the text from one box always be inserted before or After text from another specific textbox when its displayed in the destination Textbox.. (think of Textbox4 like a "preview window" of sorts.. which will later be outputted to an actual txt file.

View 1 RepliesMySQL Update Dataset With Multiple Tables - Close?
Nov 7, 2010I've been working with a remote mysql database. The design of the database pretty much requires that I use SELECT commands that include multiple tables, and sometimes joins. Updating a single table query is SO EASY, yet dealing with multiple tables has me pulling my hair out.
[Code]...
What's killing me is that if I make a change to a field in the products table in the datagridview and press button1, the changes are saved. If I make a change to a field in the specials table in the datagridview and press button2, the changes are saved. If I combine the two updates together in a single routine, only the first one is saved. I presume this is because after the first update executes, the dataadapter no longer reports that there are any changes to save, since the update already happened.
I've tried breaking this up into separate dataadapters for each table, but then even using dataset relations, I can't get the data together in a single datagridview. On top of that, the grid itself is only intended to be used for searching and querying data. It still needs to be bound along with a set of textboxes that accept the input.
Lastly, this database is part of an ever-evolving website database with dozens of tables that need interfacing. I just can't see manually maintaining hand written sql statements for every table. That's why I've been working so hard to get the commandbuilder to handle it.
SQL Performance Timeouts - Adding Multiple Rows In Multiple Tables In The Database
Sep 12, 2011I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
