Printing - Why The DialogResult = OK Is Underlined By Green Colour?
Apr 27, 2011
I have a code to print in VB.net. I don't have any problem with the printing as it works, but there is a part which is underlined by green, a warning on "DialogResult = OK". Why the DialogResult = OK is underlined by green colour? The printing work only this underline is making me puzzled
Ok, i've been making my own syntax highlighter for my project, and i need to know how to make the colour of the text between these two text values green
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?
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?
i am looking to change the windows colour and colour intensity. These settings are accessable through Control PanelAppearance and PersonalizationPersonalizationWindow Color and Appearance But is there a way that i can remotely change these two settings through functions in my windows form application? Also is there any way of removing the slight blur on the window bars/taskbar when using an aero theme?
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
I have a VB.NET form (CopyScenarioForm) with a OK button (DialogResult property = OK) and also assigned it as 'Accept Button" for the Form.
I show this form from my main Form (mainForm) using
If DialogResult.OK = CopyScenarioForm.ShowDialog() Then DoSomething() End if
Now when user clicks on the CopyScenarioForm.OK button, I want to validate his entries and if invalid I want to 'Exit Sub' from the OK button's click handler but when I do that the form still closes out and DoSomething() gets executed. Is there a way to stop this and keep the form alive and only exit if the inputs are valid. I noticed, if I change the OK button's DialogResult property to 'NONE' instead of 'OK' then it doesn't cause it to close. but then how Do I know how the user exited the form to execute DoSomething().
I have a Form that I named "Taulukonvalinta". This has 2 buttons (Ok and Cancel) that are defined as OK and Cancel.However, when I call the actions from my main form, Form1, only the "OK"-action works.>[code]
I am working on an application and have encountered difficulty using the response to a message box question. I am trying to call one form if the user clicks yes another form if the user clicks no, please have a look at my code and see if you can see where i am going wrong because no matter whether i press yes or no the frmTransactionMenu is being shown and never the frmExit
Dim response As DialogResult MessageBox.Show("Would you like to complete another transaction", "ANOTHER TRANSACTION ?", MessageBoxButtons.YesNo, MessageBoxIcon.Question)
I have the following code [code] This loop takes sometimes up to a minute to execute. I would like to display a message box giving the user the option of terminating the loop. When I use ShowDialog the loop doesn't execute until DialogResult is returned. When I use Show, the forms buttons are not accessible until do loop is finished. How can I make this work?
i want to select the next piece of text which is underlined. You see the rtf of a richtextbox has following code for an underlines text :
uli0 hello friendulnonei
But the normal text looks like underlined. What i want to do is on a click of button the rtfbox should select the next piece of text which is underlined. An example piece of text is :
hello [friend your] house [looks] amazing.
imagine the words within square brackets are underlined. When i first click button1 "friend your" should be selected and on next click "looks" should be selected. Kind of keep moving forward and keep selecting it type of application. I know this can be done using regex but can't build a logic.
i have a simple notepad application where i want a feature of selecting text which is underlined. Usually what happens is when i click a button the app reads a text file and underlines random text in the richtextbox. What i want is on the click of another button to select the text which is underlined. I thought of creating char range, regex all but not getting anywhere. I also dunno how to build a regex.
What i know is since all RTF texts are different we can choose the rtf text instead of simple text to select the underlined text. The rtf of underlined text in my application is this uli0 so manyulnonei where ul and ulnone mark the text as underlined. Now i want to select all such texts which are surrounded by uli0 and ulnonei . I thought of the following method :
1) Create another richtextbox2
2) Paste the text of richtextbox1 as rtf in richtextbox2. I mean show the text in coded rtf (like above) instead of normal rtf.
3) Use simple find to select all the text which is surrounded by ul and ulnone tags
4) process the text.
But this step is very tedious. If anyone could help me in making a simple procedure or build a regex which could process the text surrounded by those tags,
In my windows form, I have a button with a shortcut code using &. It looks like below:
It Text property has the value &Sales Bill - Cash
See that its default styling for the highlighted shortcut code is an underline. Instead, I would like to change that styling to Underline + Bold + Different color
Let assume below will be my richtextbox. This is what I have so far:
[U]Title name 1[/U] Some text. Some more text.
[U]Title name 2[/U] Some text. Some more text.
What I am willing to do now is: Only when you mouse over on underlined text - mouse cursor changes to 'Hand' Then you can click on it and message box appears with underlined text. How do I do these two things?
I am trying to create a page where a user can type a document and have it be bold italic or underlined. When the user clicks on bold and italic it should be bold and italic. when they are not clicked it should not be. I am having trouble finding a stable solution. I can only seem to change it to either bold or not bold or italic or not italic and not bold and italic.
Playing with the visual basic express, usually I'm in notepad with asp, thought I'd try some of this out. So excuse me for the green question. Down at the last three lines of code, it will not give me an absolute value of the, in fact it does not recognize it as anything.. says I have a variable that isn't declared.
I want the rdbcorrect.forecolor=color.green but is not working out for me. Public Sub VerifyAnswer(ByVal rdb As RadioButton) If rdb.Text = rdbCorrect.Text Then rdb.ForeColor = Color.Green BtnGood.Show() MyScore() [Code] .....
I have three HScrollBars(for the colors red, green, blue and maximum to 255), a picturebox(to see the output color) and a textbox which gives the color in HTML output. For example: 0xE60000FF >> This is a red color.I know I first should make a code and paste it here, but I really don't have any idea how.
I need stop printing and paper feeding in the middle of printing in dot matrix printer.(Like a POS Printer - When wrote 'End Doc' on POS printer can stop paper feeding)
I am using VB 2008 & Access Databases for creating WinForm Applications. Also i am using Crystal Reports for Report solution. my question is How do i created reports such a way that they can be printed in faster Ascii Format on any DotMatrix printer. The default true type fonts make printing very slower.
I tried to use "Draft 10 cpi" font which come to available me after i installed a correct driver for my Epson printer. which also helped me overcome this problem. however it wont be the scenario with all my clients i.e. they might have different printers having different Make with different drivers installed. i have tried to open such project on there PC but the printing wont come in Draft instead the fonts get expanded too much & the print wont come right.
