I am making a program with 2 players and I want both of them be able to select their color somehow. I know there is a ColorDialog tool but I dont know how to use it, does anyone know how to make a color selection box?
View 2 RepliesA user places the cursor in a table cell and clicks on "Table > Background Color" to edit the current background colour.Currently I have been able to detect the current colour (for instance a light blue) and set that colour in the ColorDialog (Colour swatches are correct and RGB values are correct).What I would like to do is enable the user to click on the "Add to Custom Colors" to save the colour. Problem is, it sets the first square in the custom colours area (which happens to already be filled in with another custom colour), rather than finding the next square that is white and set it there instead.

View 1 Repliesi am trying to set one of the custom colors of the colordialog to be the current background color of the form. i am doing it like this: ColorDialog1.CustomColors(0) = Form1.BackColor.ToArgb it is not working. note that i only need a specific element to contain the color. not necessarily 0, but perhaps 9 or 15
View 1 RepliesI'm developing a windows application with a form having three listviews. I've noticed that when I make selections on a listview and then click away, such as onto another listview, the original color of the selection changes.

View 5 RepliesHow do you reset a RichTextBox? I wrote some code that changes the

I'd like to change all the text in the RichTextBox back to Black and no back color.
I've got 2 radio buttons on a form and am trying to allow a user to change the color of the form based on which radio button is selected. I've used select case in a separate procedure to do this because ultimately I'd like to have about 1/2 dozen or so color options to choose from.
The color changes when the first radio button is selected (pink or green, doesn't matter), but when I try and select a 2nd option, the program crashes (VB 2010 Beta).
My code so far is:
Public Class Form1
Private Sub SetColourScheme(ByVal colour As String)
Select Case colour

I get a 'StackOverflow' error, but I don't really know what this means. NB: Adding 'Return' keyword made no difference to the outcome - same error.
I am trying to convert a value from a radio list box that is populated by an access database. The database loads fine, I have no trouble with that. My issue is that I am trying to take the value of the radio button chosen and turn it into a font color. Therein lies my problem. I see that it cannot be a string, but when I turn it into an object, I get an error. I will note that I am using VS 2008 (Windows Vista x64), and the database is compatible with a 2002 - 2003 Access database. I am using ASP.NET for my programming, however, I am trying to program it in VB. This is my code:

How can i make ONLY one selection possible from the checkedlistbox at a time? If i have already selected one and if i select another item the previous item should be deselected.
View 1 RepliesIn an application I build a list of CheckedListBox and display it to the user. I want to make the selection exclusive to only one. I noticed that you can check more that one item in the CheckedListBox. How can I stop that and as the user check the second box I uncheck his/her first selection.
SForm.ChkBoxPts.Items.Add("Paarsa")
SForm.ChkBoxPts.Items.Add("Jeff")
I.e. If I display the above two items or may be even more, I would like to force the user only select one and only one.
When setting the selection of a RichTextBox, the selected text is highlighted even though I set the HideSelection property to True. Once the RTB loses focus then the selected text is no longer highlighted. Programatically setting the focus to another control doesn't hide the selection, only physically clicking another control will hide it. So is there a way I can make the RTB not show the selection right from the start?

View 6 RepliesI'd like to force a user to make a selection from a combobox.I've tried to test it by Combobox.SelectedText = String.empty as well as another version similar to this but a little different.When I test it, it will tell me that it is still unselected/blank even when I selected something.
View 4 RepliesI am looking to after the user selects from a drop down to give read only access to the form( textboxes, buttons, etc).Upon the second selection the user would have read-write access and upon the third selection full access.Does anyoen have an example of how this might go ? I have the code in place which places the information in the drop down from the configuration table itself.

Also here is a screenshot of the options I am speaking of
There is a combolistbox that has a list of topics.
Depending on what topic you choose will determine what checklistbox option will appear in the check list box.
What are they doing there to create that option? I was thinking that maybe they created 20 checkedlistboxes and then if the selection of the combolistbox is "THIS" then they set the getfocus to that checkedlistbox but that didn't quite work for me.
how do I make a contiguous selection in a listbox like if the user shift+click even if the user control+click ?
View 9 RepliesI have a combobox linked to a table Checklist (ID, Checklistname, and several multivalued fields). I want to have my subform display data from different tables based on my combobox selection "checklistname". All the tables are imported Excel files with the same fields and field types (ie. Discrepancy, reference, reference paragraph, category). How do I get my subform to requery based on the combobox selection? Or is there another method when working with "outside tables"? Import good/bad? Make new table? I have about 20 tables, if importing but only need particular data to save/store in my main table, and I need to know which table it came from.

How can i make a control required to put input depending on the radiobuttonlist selection?
Let me try to clarify a bit more. I got 2 radiobuttons, if one gets selected, nothing else has to be done.
But if the otherone gets selected, a textfield must have some input too.
On my DataGridView one of the columns is set to a ComboBox. When I make a selection from this ComboBox the CellValue change Event is not triggered. What event is triggered when I do the selection?
View 1 RepliesI m making a "offline viewer" which uses saved webpages. I'm using a web browser and a tree-viewer. Is there a way to make the selected node in the tree viewer change if you click on a link in the web page (i.e if you select a link about The Gimp on tutorial 176, the selected node will change to The Gimp tree node)
I know about the code for changing the tree node selection, however what I'm having trouble with the web-browser side of it.
If i wanted to crop an image in VB.net, how would I go about doing it? I am trying to let the user drag out the box they want (system.drawing.rectangle), and it will automatically remove the edges surrounding the box.
My first problem is primarily the fact that I cannot make the system.drawing.rectangle visible. It is not displaying at all, I am setting its location and height programmatically, but nothing is showing up. I know there is probably something fairly obvious I am missing...but I cannot seem to find it.
My larger issue, however, lies with the cropping itself. I cannot find any crop methods, at all. Is there a hidden one I am missing? Or must I code it myself? How would I go about doing this? It ought to be able to output to a bitmap image object.
i am not able to figure out any code on how to do this. I am trying to make it so when the person chooses a color in the ColorDialog, the all my buttons forecolors go to that, then the dialog will show to pick a back color.
