View 1 RepliesVS 2010 Anyone Played With LinearGradientBrush?
Nov 20, 2011Anyone played with LinearGradientBrush? I'm using it to plot some chunky text with a gradient fill on a picturebox . Say I want the text to be full yellow at the top (255,255,0) and full red at the bottom (255,0,0). What I get is a light orange shade at the top of the letters and a dark orange at the bottom. I never get the full range of shades. I would prefer to have say 10% at the top of each letter plotted with the full starting colour, then the gradient, followed by the bottom 10% plotted with the ending colour. I hope that makes sense. Obviously I'm using MeasureString to get the height of the text and I've played with making that value larger and smaller but it didn't seem to help.I have seen references to SetBlend Triangular Shape and WrapMode which look interesting, but no examples of how these would produce the effect I'm looking for.

Feb 18, 2010Can anyone explain why the effect of a LinearGradientBrush does not always seem symmetrical?To see what I mean with the following code where point1 is halfway down the left side of the form,point2 is halfway down the right hand side.Using the colors Blue and Green the transition appears mainly nearer 3 quarters of the way across the FORM for the BLUE changing to GREEN.

View 10 RepliesCompare The Degree Of Similarity Between Two Or More Images?
Jun 15, 2011I am capturing images from a webcam and I have to compare the degree of similarity between two or more images. that is... which two images are the closest match.
I know I cannot compare the pixels...so how do i go about it?
I am using Visual basic 2010 on Win7
This comparison need to be sufficiently fast. Within 2-3 seconds.
I was looking into pixel by pixel comparison. but webcam pictures as I understand do have slight changes between frames(disturbances).
I am working on recognizing hand gestures...which would in turn control a small mechanical crane...
for example a thumbs-up sign would mean a signal for crane to be switched on...and a full palm shown would mean a stop your work sign.
I plan wearing a white glove against a black background.
I also have ideas like dividing the screen into a 10x10 matrix.

Jan 20, 2011I'm using SelectionMode as Extended (multi select) with WPF DataGrid.The SelectedIndex value always returns the first row that was selected, irrespective of the selection direction. For example, if I start at index 0 and end at 4, I can work with it fine. But if I start from 4 and go to 0, SelectedIndex returns 4 and I don't have a clue to add the number of selected cells or subtract.Is there a way to find the selection direction?

Apr 5, 2011I have a project that needs to open a CSV file that is 3.7gb in size. It is data that was exported from a database (why on earth anyone would export it to ONE file, is beyond me)
Excel/Access can't open the file because it is more than 256 columns and greater than 65000+ rows. I was able to split the file into seperate files with 50,000 rows in each. I wan't to automate this and export only data by a specific state, and perhaps add it to a database or excel file, should the rows stay below the limit.
I found a project that splits the CSV file... perhaps I can just parse the data while splitting the file.

C++ - Direction Of Shortest Rotation Between Two Vectors
Jun 13, 2012my question is regarding working out the direction of the smallest angle between two vectors in 2D. I am making a game in C++ where one of the obstacles is a heat seeking missile launcher. I have it working by calculating the vector between the target and bullet, normalising the vector and then multiplying it by its speed. However, I am now coming back to this class to make it better. Instead of instantly locking onto the player I want it to only do so only when the bullets vector is within a certain angle (the angle between the bullets vector and the vector bulletloc->target). Otherwise I want it to slowly pan towards the target by a degrees thus giving the player enough space to avoid it. I have done all this (in a vb.net project so i could simplify the problem, work it out then re write in in C++). However the bullet always rotates clockwise towards the target even if the quickest route would be counter clockwise. So the problem is working out the direction to apply the rotation in so the smallest angle is covered. Here is my code so you can try and see what I am describing:
Function Rotate(ByVal a As Double, ByVal tp As Point, ByVal cp As Point, ByVal cv As Point)
'params a = angle, tp = target point, cp = current point, cv = current vector of bullet'
[Code]...
I had was to work out the bearing of the two vectors and if the difference is greater than 180 degrees, rotate clockwise otherwise rotate counter clockwise

1. The textbox is not having them 1 by 1 for example

it has to be implemented into the toolkit anybody have any ideas how without a database if possible. I thought this could be done in the load form, pre-loads the software and then checks when comes to installing the software in the list.

May 21, 2009Total noobie when it comes to VB, but I'm jumping in. I have about 15 years with Business Basic and see many similar things between VB and BBx so hopefully the learning curve will not be to steep.
Anyway the project I wish to complete is: Use portable computers running Windows CE 5.0 to scan bar coded labels to capture data collected during a physical inventory. The labels have 2 fields - bin location and item. My form will have a textbox for 3 items - bin location, item and quantity. Also, the form will have 2 radio buttons to accept or reject entry. I plan on writing the records to a simple text file to import in to the current application I am running.
I downloaded Microsoft Visual Basic Express 2008 and have done a little prodding around so far. I know the Express version does not support mobile device application development so that needs to be upgraded. My question is, can someone recommend a good book that would cover the areas I need to be concerned with?
Also, any good online resources?
Customizing ContextMenuStrip Arrows And Open Direction?
Oct 14, 2010Trying to create a custom button to reside on the desktop at:
Me.Height = PictureBox1.Height
Me.Width = PictureBox1.Width
Me.Top = My.Computer.Screen.WorkingArea.Height - Me.Height
Me.Left = My.Computer.Screen.WorkingArea.Width - Me.Width
The trouble is all the arrows point to right, and the menus open variably depending on size.
Is there anyway to make the arrows point left and make all menus open to left in same direction?
Also, Is it possible to make the width of my form autoresize to the size of a label and the image box, while keeping the imagebox at the bottom right of the screen showing the populated label to the left?
