Basic Search Doesn't Compare Selected Element With Textbox Value
Sep 17, 2011
I've been having problems with a really basic search routine that I have used successfully before but now for some reason does not. I have a text file that looks like this: Spindly Killer Fish, fish, spindly, aggressive, dangerous, grey, Sect.B Tank.1, 20 It is then loaded into a two dimensional array with comma separation. This is all fine and with the following nested for loops it works also, it just doesn't seem to compare the selected element with the textbox value. [Code]

unordered text file of 3 columns to assign into 2 arrays. I've been given a graphing component which expects a two dimensional array for a scatter graph for the set of values in the last column.
How would I parse through the list given an indexed array of 215 possible 'zone alarm locations' and if an alarm log list item, of which there can more than one for any given zone location, compare in the two dimensional array any previous value and replace it with the higher valued one? The following are my declarations for the 2 arrays. It isn't clear to me why the array for the scatter data was defined as (999,1) knowing there are only 215 possible x values (alarm zone locations)

I have a web browser setup and in that browser I customized the right click options to use a Context Menu Strip to add a few right click options to my menu. In the menu I have added a right click option for the name "username"...what I'm trying to do is when I find the username text box on a web page I want to be able to left click in the textbox to get the focus and then right click to go to my menu, choose the right click option username.

ok, so i want to invoke a click on this element
<div class="round spacer listTitle" onclick="Travian.Game.RaidList.toggleList(5101);">
however, this doesn't have an ID so i can't simply use GetElementById. if i were in JS i would use a 'GetElementsByClassName' and then set an index to find the element i want to use but i am not sure if vb.net has such a function so i thought about trying to call its parent element which does have an Id but this does nothing.
webBrowser.document.GetElementById("list5101").InvokeMember("click")
i have also tried using the 'GetElemenetsByTagName' (i actually was using this thinking it was a GetElementsByClassName which is probably why it didn't work, whoops) so i was thinking about using GetElementById to locate the parent element, list5101, and then if possible find the child node i want and triggering it like that. or maybe i could just call the javascript function outright ?

I want to see if try cast can convert user entered answer to the type I have specified. Here's what I have: Dim t as type = GetType(myType) Dim ans = console.readline() If TryCast(ans, t) <> Nothing Then ... 'Doesn't work` In the example above the intelisense doesn't even show t. How to make it work?

I want a string search/compare with wildcard. I'm trying to create a "crypto crossword" application and got most of the code working but the wildcard thing was harder than I thought.
Basically I want the program to compare if "H**LO" is equal to "HELLO" (true). But "HE*" is NOT equal to "HELLO". I tried with regex but the number of wildcard is different each time and in different places so I never managed to make it work.

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
DataString.Split(New Char() {";"c})
Pass through
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

My program can detect when Aero is present, but it has trouble when the user is in Aero Basic because it doesn't use the transparency or glass look. I am wondering if there is a call to the dwmapi that can tell me if the computer is using Aero Basic.

When I launch VB Help and do a search it shows under "Local Help", "Exception from HRESULT:0x8004032E". It lists three results under "MSDN Online", but the large field to the left of it is entirely blank. If I double-click blindly in that blank area it brings up various topics as if they were listed there but invisible. Further, the region under "Contents" is also blank, as is the "Filter by:" field. If I click the down arrow by the "Filter by:" field it brings up an entirely blank menu. If I then click outside the menu box it brings up a message saying "The selected filter contains an error that prevents it from being applied.". What's wrong and how can I fix it?

Hi, I have a project that works with a database. It groups al my films per category. I use this code to group everything by category. The categories are chosen in the combobox cboCateogorie.
Private Sub cboCategorie_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboCategorie.SelectedIndexChanged
If Not cboCategorie.SelectedValue Is Nothing Then
cboCategorie.DataBindings.Clear()
cboCategorie.DataBindings.Add(New Binding("Text", objDtsMuziekcollectie.tblCategorieen, "CategorieID"))
Dim dtvDVDInhoud As DataView
dtvDVDInhoud = objDtsMuziekcollectie.tblDVDInhoud.DefaultView
dtvDVDInhoud.RowFilter = "CategorieID = " & cboCategorie.SelectedValue.ToString
dtvDVDInhoud.Sort = "DvdID ASC"
objTblDVDInhoudBindingSource.DataSource = dtvDVDInhoud
Me.objTblDVDInhoudBindingSource.MoveFirst()
End If
End Sub
Now I've made a textbox and a button which I can search with. But I want that my category in the combobox changes when a film is selected with that search. Now I already have this code to search with a joker sign.
Private Sub btnZoek_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnZoek.Click
Dim dtvZoeken As DataView
dtvZoeken = objDtsMuziekcollectie.tblDVDInhoud.DefaultView
dtvZoeken.Sort = "DvdID"
objTblDVDInhoudBindingSource.DataSource = dtvZoeken
dtvZoeken.RowFilter = "Titel like '" & txtZoekveld.Text & "*'"
End Sub
Ok, so what I want is the opposite off what I do when I select a category in a combobox. Now I actually select a film and this film also has an ID, namely DvdID and with that I want that the combobox shows the category where the film belongs to.

Why can't you set the selected integer for the items in the combobox in the properties window instead of adding code in the form load event? I don't like to have to do things that way, I feel like it is less efficient. Should I just deal with their being no value property for combo boxes or is there a way to do it easier?

I am using VS2008, vb.net, Windows forms project.I have a combo box control on a tab control.The selected value of the combo box is bound to a binding source.The data source of the binding source is a typed dataset.I set the datasource of the binding source when a record is chosen in a data grid control.Since the combo box is bound to the binding source, this should set the selected value of the combo box, and fire the initial SelectedIndexChanged event.Therefore, I remove the SelectedIndexChanged event handler for the combo box before I set the datasource of the binding source, and add the handler again after the datasource is set.
