View 2 RepliesTo .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 GFX As System.Drawing.Graphics = System.Drawing.Graphics.FromImage(BMP)

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?

View 1 RepliesI'd like to replace all the white pixels in a bitmap image with pixels of the colour "Color.FromKnownColor(KnownColor.MenuHighlight)".

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]

View 7 Repliesi am making a richtextbox and some buttons,i want to press a button while some text is selected ,the selected text becomes bold or underlined,
View 2 Repliesi 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.
On a button click i want to first select "vb dotnet forums" and on next click immediately select "are the best" (in a richtextbox control) .
View 6 Repliesi 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:

I am getting error in the sheets and iffset liness.. it says
Sheets("Sheet1").Cells.SpecialCells(xlCellTypeLastCell)Offset(1, 1).End(xlToLeft).PasteSpecial(xlPasteValues), underlined words aren't declared
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.
