I am trying to filter a ListBox based on the presence of a string. Basically, if there is a ListItem that doesn't contain the string then I want to remove all ListItems that do contain the string. Here is what I have tried:
Dim Item As ListItem
For Each Item In CtheList.Items
If Item.Text.IndexOf("W:") = -1 Then
[Code].....
in short I just want to have constantly running in the background something to display in LB8 the the contents of LB 2 that contain what is typed in TB1
1Private Sub Name_Change_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
2Dim filtertext As Integer
3filtertext = ListBox2.FindString(TextBox1.Text)
4ListBox8.Items.Add(filtertext)
5End Sub
How would I check a given string for the presence of any match with a character listed in another string. I'm just looking for a binary result.
In other words, how would I write the VB.NET function called IsPresent in the following code snippet?
Result = IsPresent(AnyString, MyTestString)
For example, if MyTestString = "XYZ" then I want the following results for the given AnyString values:
MUTTON, Result = No
BUZZ, Result = Yes
HAPPY, Result = Yes
FISH, Result = No
Everything is written in codes:
vb
'CHECK IF "sIntroSequence" IS AVAILABLE IN TEXT FILE. Dim checkthevalue As String = My.Computer.FileSystem.ReadAllText("c: est.txt") If checkthevalue.Contains("sIntroSequence") Then '"INTRO SEQUENCE" STRING IS AVAILABLE. 'CHECK
[code]....
I can't seem to get the checkbox checked according to presence of a particular string in a text file. It looks like it should work but it doesn't.
I'm trying to write a small app which can be used in order to log off Citrix Sessions. Citrix Sessions can be logged off via cmd or a batch file using this method:

So basically what I want to do is to select each listbox item that matches one of the hits from the cmd command. Probably the servername that gives a different result than "No User exists for" How can something like this be achieved?

View 5 RepliesI am looking to find the best way to do the following: Filter data based on the drop down filters, as long as I am within the same product category (e.g. toys, puzzles, etc...), but in different web forms (product grid and product detail).So if I select toys under $25, I need the filter to the toys in a grid format, but if I click to view the detail I need the filter information so I can filter the related items display.Display certain filters depending on the product category.Right now I believe that if I build a user control and session variables that I should be able to accomplish this.
EDIT: Right now I am using the page_load event to update the data and would like to avoid AJAX for right now.

I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

View 14 RepliesI am Working VB.NET 08 Windows Appl.I Have Combobox and DataGridView in the Form.In the Combobx Having Names list Called "SurName".In The DataGridView on of the Column is "SurName".So when change the data on the Combobx list the dataGridView is Filtering and displaying the values correctly.For this i wrote a code in Select IndexChanged or SelectionCommitedChange Event.

For Ex: Names are like 'Mali', 'Malu','Maal','Mouli'.
If i type 'M' letter in the Combobox then 4 rows Filter in the DataGridView.
If i Type 'Ma' then 3 rows ,
If i type 'Mal' then 2 rows,
If i type 'Mali' then 1 row.
I have a database with a table that is a child to many other tables. I am using this child table as a datasource for a datagridview. I am using comboboxes to display specific fields in any parent tables, instead of the user seeing the foreign key. Everything is fine. However, I would like to filter the BindingSource based on text matches between any of the fields in the child table and the corresponding fields of the parent tables.

In vb2010 I started getting an error message because I was still using FileListBoxes from VB6 and now they supposedly aren't supported in 64 bit systems. So I am replacing those with ListBoxes. I got the images to load fine into the list box using the FolderBrowserDialog. but (see the snippet below), I want to filter for several image types, not just one or a generic wild card which would pull in even non-image filetypes. This language will only accept one extension wildcard parameter it seems:
(sp is a string containing the folderbrowser dialogue path)

I have a text box and a list box, my ultimate aim is to use the text box to filter the list box. The below code works however the text box is case sensitive and I need the user to be able to input any case and it filters the list box accordingly, at moment.Example

"my site" = Works
"My Site" = Does not work[code]........
I am currently using the following code to check for the presence of an entry in a table. I choose this code because I thought it was a good idea to use a public function to reduce the amount of code required. It works fine until the field I am checking for contains a' character.I realise I need to use a parameter like @name but cannot work out how to pass the correct information to the public function.how to amend my existing code so I can use @staffNo.
Imports System.Data.SqlClient
Dim PaddedStaffNo As String
PaddedStaffNo = (TextBox2.Text.PadLeft(4, "0"c))[code].......
I am working on a solution to a problem at work where we can't tell if someone is on the phone or just sitting there. We use Microsoft Lync to place our calls and I was hoping to be able to add a bit of code to an existing .net application to show the presence of the person logged into the machine. That info will send that out via USB to an indicator light I previously built.
So basically I am trying to create a .net version of those 'ON AIR' lights you see at radio stations.
I have been searching for the last few days and haven't found a solution. I also downloaded the Microsoft Lync Controls SDK, but no luck with that either.

I have a form with 4 comboboxes and a button. The first combobox is enabled, but the rest of the controls are disabled. When the form is opened I fill the first combobox (cbxMethod) with a datatable. When the user selects something in cbxMethod the next combobox (cbxStudy) will be filled and so on. When the last combobox (cbxAnalyte) has a selected value I want to enable the button and give it focus so the user can move forward with the program. I basically want to force the user to move from one combobox to the other, until all are filled.I am currently using the SelectionValueChange event, but this event only fires when the user changes the value with their mouse or hits the Enter key, not when the user hits the Tab key.

Just wondering if someone can at least point out where I'm going wrong here. I've already got the code to populate the listbox by a button click from the user and am just trying to figure out how exactly to alter the text of a label based on what the user selects in the listbox. From what I have the Label will display the case else selection but nothing else despite my best efforts to get it to change. Here is what I've tried. I realize it is very trivial, but I am only a beginner to programming.
