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)
im trying to add in a filter which removes any item in a listbox which doesn't contain certain words, the filter is enabled by checking a check-box, and the listbox is populated with the names of the sub-folders with in a user selected folder.im a little stuck on what to put in under the 'if di2.contains blahblah" to tell it to then only list the folders which containing those words in the listbox.[code]
I'm using VS 2010 professional and the basic programming language. I have an access database which is pretty simple. I have 1 table named Cards which have 4 feilds Question, Answer, Topic, and Source. I've got two other table which hold the lookup values for Topic and Source.On the Form I've got 2 bound listboxes for Topic and Source. I want to populate a third list box with the Question and Answer based on the records in table cards who's Topic and Source feilds match the selected items in the other 2 listboxes.
I currently have a massive list of names and want to narrow it down via a filter from a listbox. I honestly am new enough that a datagridview is beyond me and something I want to tackle eventually, but this is the last thing I need to roll out the project and just want to finish it.So I am running the contents of the textbox through an if statement and populating a new LB based on the results:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged If TextBox1.Text = "" Then
i am trying to create a search function/filter for a list box basicly when i type a letter or letters into a text box i want the listbox items to be filtered so say i have 5 names in the list box as follows:
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
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
I'd like to ask assistance for the following scenarios below:
1. I want to check whether certain applications are already running or not. 2. The applications i need to check are the ff: a. MS Word b. MS Excel c. Notepad d. MS Project e. MS Powerpoint
3. If any of these are running, the window title of that application will be filled-in in a listbox.
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" = Works "My Site" = Does not work[code]........
How can i go about associating my application with a filetype e.g *.safsg ? How can i get my program to open them file types when that filetype is double clicked on desktop for example.
How do you associate a filetype, for example ".tkoen" (idk..), to the registry without restarting Explorer.exe for updating the filtypes..in Explorer.exe..?
Is there a way to get a list of all files in a folder but exclude a certain filetype/extension? Or is the only way to do it is to get all files & loop through them & exclude the filetype with an If statement?
the function to call the command filetype=jes. My calls to the ftp site arequote site filetye=jesasciiput filename.extquote site filetype=seqI have looked at the system.net.ftpwebrequest class and it works great for sending and files but need this one command to finish the call
I am trying to select a folder in a very similar way that we do using "OpenFileDialog". I searched for different sites and did find something but all of codes were tweaking "OpenFileDialog" and selected files..... I have seen applications where the select dialog box does NOT show the "File Type" as well as the "Open" button has "Select" name on it. Any idea how to get such dialogbox?
I am trying to filter the results of a datagridviw using the bindingsource.filter method.
Dim filters(2) As String ... If Me.txtPartIDFilter.Text = "" Then
[code]....
The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.
i want to filter date and also time (shortime) for example if Datum.hour="8:15" andalso Datum.day of week "Saturday"or "Monday" now i can only filter date ... this is my filterline objbindingsource.Filter = "Datum > = '" & Dtp1.Value.Date & "'"
I want to filter a text in all columns in a datagridview. So I use Like % in the filter text. However, I found that the text(strFilter in my code) may contain % sometimes. So it have a syntax error. How can I use filter with like clause when the filter text contains %?
Private Sub PassFilter(ByRef dataTable As DataTable, ByVal strFilter As String) Try Dim dataview As DataView = dataTable.DefaultView
Apparently, filetype refers to the extension of the program. But I do not want it to read .exe and .lnk programs. So how can I include this "If Else" statement into the one stated above?
If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.
The scrollbar that comes with the ListBox is too small for touch screens, so I use my own scrollbar instead. But when you do this on various forms you end up repeating a lot of code. So my solution was to create a custom scollbar that has a property I can set to the control I want it to be a scrollbar for. In vb6, I can use the withevents keyword to get access to the control's events so that all the scrollbar related code can be in the custom scrollbar object I created, except...I had to create a refresh method for the consuming code to use to let the scrollbar know when the number of items changes. The scrollbar doesn't need to be told how many items there are because it has access to the control, but for a listbox there is no event to tie into when an item is added/removed so not 100% of the scrollbar related code could be encapsulated.
Is it possible to select an item in one listbox and then display the data of another listbox with the same indexed position? I am planning a project and this is something I would like to attempt but I haven't figured out how to do it.[code..]
I tried doing the above code but instead of displaying the listbox text the message box just returned false.
I am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.
