Assigning Text Colors To Individual Dropdownbox List Items?
Apr 18, 2012
This is a WinForms Application in VB. In my application I am trying to make it easier for the user to pick out items in a list quickly based on the items text color.. So I am trying to assign the color to each item using a select case statement as below... The problem is that I am getting an error saying "Public member 'Attributes' on type 'String' not found." VB flags the lines with the Attribute.Add param with this error.. Here is the code that I currently have...
For Each u In _units
_counter += 1
u_lookupNumber_box.Items.Add((Convert.ToString(u.UnitId)) + " - " + (Convert.ToString(u.perMonthCost)))
[Code].....
I did notice that when I did the .attributes part when I hit "." and typed "att" it did not appear in the intelisense box in vb.. Which makes me think I need to assign the name "attributes" somehow to the dropdownbox first.. It should be noted that u_lookupNumber_box is the name of the drop down box on my form..
I have thius code that gets the html results of google search
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted Dim PageElements As HtmlElement = WebBrowser1.Document.GetElementById("rso") TextBox2.Text = PageElements.OuterHtml Dim text = TextBox2.Text End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click WebBrowser1.Navigate(TextBox1.Text)End SubAnd it returns the html code.I want to get each list item and takes it html and put each individuals html in to a variable. How would this be done.
Is it possible to Insert text with different color in the same list box ? For example , the contents of the list box could be :Line 1Line 2Line 3Line 4
Problem: I need a way to have individual notes for all the items in a listview. Tools: 1 Listview, 1 button and 1 Textbox.I would like to click an item and have notes for that item pulled from the settings.When the button is pressed I want the notes for the item to be saved in the settings.
I have a dilemma whereby I have a form which contains a number of comboboxes that contain information/options/items that may be invalid/out-of-date in certain circumstances.I can't simply remove the out-of-date information from the items, but I do want to give the user a visual-clue when options are invalid.
I have a huge assignment tommorow in which i have to make a trivia game on visual basic. In this game you have to be able to make your own questions (modify/delete etc). Basically I have one form where you can add questions into one listbox and answers into another listbox. Now i have another form with the actual game board. I want to load each individual listbox item from the other form into the array on the game board form. Example. the first item of form2.listbox1 into question(1)
I got this so far

I have 2 projects where I have to assign certain items to buttons, and I am getting the following error message: Error1'videotype1' is not declared. It may be inaccessible due to its protection level.C:UserschrisAppDataLocalTemporary Projectsvideo bonanza 1chris's video store.vb49video bonanza 1
Here is the Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click videotype1.text = "aisle 1" End Sub
I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.
I can't seem to find any answers that work. Here's the setup:
Info class: Public Class ProductStageInfo
[Code]...
maybe I just don't understand the whole collection/index/thing. All the examples I've found are regarding single dimension collections - 'how to find name within this collection', and the responses use strings to search through them, but somehow the Info class is being treated differently, and I'm not sure how to translate this..
I have a combo box which will store a list of RGB values generated when the user makes a custom color in the color dialog. The values are stored in the combo box in RRR, GGG, BBB format. I have this working. The code for this is as follows:
dlgChooser.ShowDialog() Dim colorR As String = dlgChooser.Color.R.ToString() Dim colorG As String = dlgChooser.Color.G.ToString() Dim colorB As String = dlgChooser.Color.B.ToString() lblTitle.ForeColor = dlgChooser.Color() cmbRecent.Items.Insert(0, colorR & ", " & colorG & ", " & colorB) cmbRecent.SelectedIndex = 0
The next part is to change each recent color's background color to match whatever color the values represent (so that it's easier to pick from the colors). How do I assign a background color to each item listed in the combo box?
I am trying to add items from a text file into a list box...I got that far. Now I want to click on the item in the listbox and have coresponding information appear in a textbox. How might I do this? I know it has to look something like this>
lstbxdisplay.Items(lstbxdisplay.SelectedIndex) = Textfile information Then textbox1 = " "
I know this must be more simple than i'm making it out to be, but it's not working for me.I have a listbox with items that are set up in a specific order and need to be kept in that order when going into the text box line by line.
how to set the value of the text that is displayed for each item of a list control, such as a checkbox list, but really this applies to most list controls, not just the checklistbox control.
I have a checklistbox control,
Friend WithEvents clstTasks As System.Windows.Forms.CheckedListBox
that I usually want to populate with a list of task names. I call the add method to add a Task object to the list. I know that if I override the ToString method, whatever value is returned by that function will be displayed as the text for the list item.
However, in rare situations, I want to display something else other than just the name. For example, perhaps I want to display the name and the value of another property, such as the value of the Boolean property "Optional" shown in parenthesis following the name.
The best that I can think of is to define a property which is set in the GUI layer and then used by the ToString function to determine how it should behave when called. If the controlling property is set to one value, the ToString will return the Name, else it will return the Name followed by the value of the Optional flag. This seems a little disjoint a kludged to me.
The other alternative which seems a little overkill is to define a new class which inherits from Task, for example TaskOptional, which overrides the Tostring method on the base class. In this subclass, the ToString function would return the Name/Optional flag value. However, this, too, seems a little nuts to have to come up with a new class just to modify how the text is being displayed in the presentation layer. I feel that I should be able to control this in the presentation layer without changing the business object or creating a new derived object.
What is the best way to accomplish this?

I am currently working at an, as the topic tittle says, ListBox control, writed in pure GDI to inproe my GDI skills.The problem is the ListBox items (defined as ListeItm), i tryes to make the ListBox items to show up every other in two different colors.
To do so, i have created a boolean called "lf". When the ListBox item is created it checks what the value of lf the last Item got, and chose the opposit, but somehow, it is not working.

I want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?
I have figured out how to populate the comboboxes for an app I'm making from a database this is not the actual code but is basically the way I'm populating them for i = 0 to maxrows - 1 cbobox.items.add(dataset.tables("datatablename").Rows(i).Item(x))next i need either to be able to manually assign an index value to each added item or at least figure out how vb.net manually assigns index values to these.
im trying to do is find out the command to compare itemview items with textbox, so i dont end up with 2 of the same customers when i add a new entry, if anyone could give me some advice i would be greatful just a hobby, bold line is my problem in script, need to try and replace.

How can I make certain items in my content menu Bold or a different color etc etc i.e. menuitem3.bold=true Dim buttonMenu As New ContextMenu Dim MenuItem1 As MenuItem Dim MenuItem2 As MenuItem Dim MenuItem3 As MenuItem menuitem1.text="Choice 1" menuitem2.text="Choice 2" menuitem3.text="Choice 3" buttonMenu.MenuItems.Add menuitem1 buttonMenu.MenuItems.Add menuitem2 buttonMenu.MenuItems.Add menuitem3
I want a context menu strip to have 4 specific items. For testing purposes, we call them Item1, Item2, Item3, and Item4.I've set up a context menu strip like this, and I am using it for about 20 different controls. I want these four items to do different things based on what control the user right clicks. The only way I could think of doing this, was to make 20 context menu strips and create a click event for each item. This obviously, seems like a really bad way of doing it.Does anyone have any suggestions or another way of making the click events for the individual Items based on what control is right clicked?
The program I am trying to make needs to be structured like this.
Table 1: Estimates (Details View) Customer ID Employee ID Form Factor Problem Proposed Solution Estimate Acceptance (Boolean)
Table 2: PartsList (Grid View) Part Number Part Name Part Cost
Now, the trick is, I need to have it where each Estimate can have its own individual parts list. It needs to be this was as each estimate could have just one part, or many parts. How can I do this effectively? I already have the tables and the layout of the app, I just need to get it all connected up.
I have made a little application for me and my friend to be able to chat with eachother, but now we have some unclear strings as you can see on the image below:
I would like to change for example the username or time date to a color or make it bold, could anyone tell me how to change ONLY that and not everything? I'd love to have such a thing as it makes the whole application way 'clearer'.
I need to load a large txt file that is in a fixed width format. There are over 45K lines, so speed is important.I need to load one of the fields into a dropdown box and have another field (label) display the text of another field in the related line.I could import the file to an access db if needed, but would rather not as i also want the txt file to update from a link on a regular bases. So having it in a DB would be more work to process that part.[code]
I've got a stupid question (i think) I need to convert a textbox into a dropdownbox, end let it respond to the text the user is filling in.Here's the From as it looks and works now:
What i want is this:As the user starts typing a name in textbox Naam (searchbox) which needs to become a dropdownbox, it should drop down and show all the matching data in data row Naam (my second row in the data table), so that the user can then select one of them and all of it's corresponding data is shown.
So far i have been able to convert it into a dropdownbox, but then it only searches for Naam, but does not display the rest of the data.For example:I have the data of 1 client on screen, his ID is 4, then i use the dropdownbox to search for another client, it finds the other client, but it displays only Naam and not the corresponding ID and other data.
Im doing the same thing as him but in vb express 2008 what i have is a checklist box of 10 toppings, all of which can be selected, (no max or min) to put on a pizza, and i have 3 radio buttons grouped together for pizza size (S, M, L) i cant figure out how to give them vaules in which(for sake of demonstration) s=$5 m=$7 l=$9 and each topping is $0.25 then make them add up to an order total in a msg box or something like that
I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then EnglishForm.Show() ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.
I have a list of colors i.e.: "1323523, 12342, 2354, 356234, 234234"Each of these numbers stand for a color. I would like it so that when there is colordialog.showdialog, this list of colors shows up in the colordialog custom boxes. This is how i am doing it currently, but for some reason the customcolors are not being added. i know for a fact that my array is good because i checked it.
How can I display a color dialog with a list of known web colors for the user to choose? E.g. black white dimgray gray darkgray silver etc. I need to display ALL web colors
