.net - Show A Selection Border Rather Than Back-colour In A DataGridView?
Jun 15, 2009
My DGV has row BackColors set to various colours based on business logic. When a user selects the row the colour changes to the selected row BackColor thus obscuring the pre-set colour. I would like to preserve the original colour when a row is selected and indicate selection with (perhaps) a bold border around the selected row.
My VB2010 programme changes the background colour of a button (butExtra.BackColor = Color.Red). But how do I restore the colour to the default "Control" colour?
Is there any way to change the default colour to the highlight when a listview row is selected? Apparently the default blue colour causes some problems for some users who have some visual eyesight problems. They didn't tell me what colour they wanted but they did indicated the blue is annoying.
I attached a image of menu bar. I set the background color which is the form background color. But when run the application the color is still default.
i hav a transparent png. i need the form also to be transparent so what i did was set the transparency key to the form back colour see what happens (it is in the pic)
I'm making a datagridview, and I want to remove de cell selection border.
I tried to put these:vb
Private Sub dgvL_CellClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dgvL.CellClick dgvL.DefaultCellStyle.SelectionBackColor = dgvL.DefaultCellStyle.BackColor dgvL.DefaultCellStyle.SelectionForeColor = dgvL.DefaultCellStyle.ForeColor
I am looking for a regular expression that can convert my font tags (only with size and colour attributes) into span tags with the relevant inline css. This will be done in VB.NET if that helps at all.I also need a regular expression to go the other way as well.To elaborate below is an example of the conversion I am looking for:
<font size="10">some text</font>
To then become:
<span style="font-size:10px;">some text</span>
So converting the tag and putting a "px" at the end of whatever the font size is (I don't need to change/convert the font size, just stick px at the end).The regular expression needs to cope with a font tag that only has a size attribute, only a color attribute, or both:
I also need another regular expression to do the opposite conversion. So for example:
<span style="font-size:10px;">some text</span>
Will become:
<font size="10">some text</font>
As before converting the tag but this time removing the "px", I don't need to worry about changing the font size.Again this will also need to cope with the size styling, font styling, and a combination of both:
I am extracting basic HTML & text from CDATA tags in an XML file and then displaying them on a web-page.The text also appears in a rich-text editor so it can be edited/translated, and then saved back into a new XML file. The XML is then going to be read by a flash file, hence the need to use old-fashioned HTML.
The reason I want to convert this code is mainly for display purposes. In order to show the text sizes correctly and for it to work with my rich text editor they need to be converted to XHTML/inline CSS. The rich text editor will also generate XHTML/inline CSS that I need to convert 'back' to standard HTML before it is saved in the XML file.I know the temptation will be to tell me a number of different ways to set up my code to do what I want but there are so many other permutations I haven't even mentioned which have forced me down this route, so literally all I want to do is convert a string containing standard HTML to XHTML/inline CSS, and then the same but the other way round.
I would like to change the dropdown list and whenever I make some changes it should auto post back and triggers a selectedindexchanged event for drop down list. I am having problem where it does auto post back but doesnt remember what I selected, it refreshes my page and item that i selected gets lost. I would like to do this without AJAX call. But, if AJAX is the only option, I am open to it.

I'm creating a basic text editor and I wish to include the option to change the font, font colour and background colour of the text box. Is there a way I can ask VB to display a font/font colour selection box or do I have to populate a combo box and code it all myself?
I have a function that i use to save a datagridview row to an access database (which works fine) but i was wondering any one know what i should look up to figure out how to set the row that i am saving to a colour IN the access database. So the row that i save is say red in the access database.
Im using vb2010 express. I have a datagridview in my form. All my cells in the datagridview has a "sunken" cellborder. When mouse is over a cell, i want to change the cell border of that cell to "raised". I tried lots of thing, but i havent suceeded to change just "one" cell's border.
To .NET after getting tired of using VB6 due to the lack of functionality. I'm trying to create a log on method for a system which will involve users selecting a colour from a paint panel and then placing/drawing the colour in 1 or more tiles of a grid, basically a 3x3 grid in which for example they selected the blue colour and drew in the top left tile and the bottom left tile. The logon is selecting the correct colour and placing the colour in the appropriate tile. What i want them to be able to do is place even a single pixel of colour so it has a high accuracy. So far i have a timer which loops from the width of the grid to the height of the grid.
Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick Dim BMP As New Drawing.Bitmap(1, 1) Dim GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP) GFX.CopyFromScreen(New Drawing.Point(MousePosition.X, MousePosition.Y), _
[CODE]...
To start with i have just hard coded the colour i want it to detect. At present it produces an error. Parameter must be positive and < Width the error is on System.Drawing.Point(i,j). If i place the mouse over the colour then run the program it will say it has been found, but otherwise it wont find the colour. I believe i am not updating the location of the pixel or something to that effect.
I've got a combobox which loads the system colour list, the selected colour is stored in the registry (i've tried storing the index number value aswell as the colour name - how can i get the combobox to display the stored colour as the default colour when the form loads? It always defaults to the first item in the colour list I've tried
So I have got a program with a timer on, a few labels displaying coordinates, and two buttons. Here is my
[code]...
It displays the color of the pixel at the coordinate typed into the text boxes.I have a video of a tennis ball which is bouncing on the spot, and the background in brown, so when the tennis ball comes into view there is a significant color change and i want it to start and stop a timer each time the colour changes significantly.So my question is, how do i get it to check whether the colour chas changed significantly?
In VB.NET 2008 I've two forms 1 & 2 containing two datagridviews connected to two data source 'ACCESS 2007 tables' Now I want to select multiple rows from one datagridview (form1) & transferring these to another empty datagridview (form2) with a button_click.
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?
I am interested in showing list of 12 months like in similar way to datepicker's month selection control. But i don't like to show the date picker to show the dates of that month too... only month view is ok so that i can select month from the list.

Also is there any way of removing the slight blur on the window bars/taskbar when using an aero theme?
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.
I want to include the ability for the end user to create connections to different databases using the same (or similar) dialogs that are available at design time, such as the Connection String builder, Selection Data Source (ODBC) screen, etc. Is this something built into .NET or only available via third party/custom controls?
I'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)". Is there some method in the Image, Bitmap or Graphics classes I can use, or will I simply have to inspect each pixel in the image with GetPixel, check whether it is a white pixel, and then set it with SetPixel?Here is the code I am using now:
Private Shared Sub highlight(ByVal b As Bitmap) Dim highlightColour As Color = Color.FromKnownColor(KnownColor.MenuHighlight) Dim whiteARGB As Long = Color.White.ToArgb
