VS 2010 Anyone Played With LinearGradientBrush?
Nov 20, 2011
Anyone 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.

Can 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.

I was wondering if there is an easy way to analyse sound that is sent to the speakers (just before it's played). For example when playing a song in winamp or windows media player. Or is it easier to write plugins for those programs to form an interface with your own program?

i make a simple winform application with AxWindowsMediaPlayer and timer.
My objective is about to make the application play the clip with interval (that's why i use timer)
When AxWindowsMediaPlayer finish playing the first clip, everything's okay. But when it begin playing the next clip. It CAN'T HAVE FULLSCREEN MODE. I have to double click the control manually to have it fullscreen. I use vb 2005 in 7 ultimate.
Here is my code
Private Sub AxWindowsMediaPlayer_PlayStateChange(ByVal sender As Object, ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles AxWindowsMediaPlayer.PlayStateChange

I need to adjust the volume of this audio clip to make it blend with other system sounds (also played from My.Resources). I've tried looking this up in the help screens and found nothing. Is it possible to do?

I have mp3 database (access). I want to filter table and show 100 most played songs. There is a field "PlayCount" which is increased every time the song is played. I know how to use TOP clause, but there is a problem when I want to sort results in descending order by "PlayCount" .here is the sql query:
SELECT TOP 100 * FROM Database ORDER BY PlayCount DESC this query returns 120 results. If I use "TOP 200" it will return 278 results. But everything works fine if I use ORDER BY Filename.

I want to make a program that detects the note that is being played in front of the microphone. I am testing the FFT function of Naudio, but with the tests that I did in audacity it seems that FFT does not detect the pitch correctly. I played an C5, but the highest pick was at E7.I changed the first dropdown box in the frequency analysis window to "enchanced autocorrelation" and after that the highest pick was at C5.

I have seen similar questions which attempt to solve this issue, but none seem to work for me so far.Basically, for my first VB project, I am creating a virtual keyboard where a sound is played from the resources on KeyDown. So far, the program seems to work except for the fact that each key needs to be clicked by the mouse before the sound is played by pressing each key (hence put the object in focus), where I need the key to play the sound without clicking the keyboard key (put the object in focus on KeyDown).Below is an example of my code:

I was just thinking if there is any component which monitors sound output. My intention is to recognize a particular sound coming out from my soundcard. I know its an issue about the driver of my sound card but is there a way I can get atleast noise level coming out of my speakers and maybe draw a graph and detect the peak at when the sound is played?

I need to get a button to enter the applications subfolder and randomly select 1 file to be played in the windows media player COM which i have put in the form. I have tried creating a shuffling playlist but i cant get it to stop after one file is played (it just goes on shuffeling to another file, and i really do not want a playlist). I manage to create a batch file to be started to randomly pick a file in that folder, but when i do this the file is being played in the systems default player..

Im trying to capture the audio played on my laptop. so i have searched the internet and found a source code for doing exactly that. the problem i have is that my audio device is not listed in the dropdown box (see picture) but it does when its run on windows xp (im running windows 7 x64) the goal of this application would be to capture my friends radio stream and save the individual played mp3's to a loction on my hard drive.(yes i have permission) i have included the source code so perhaps some 1 could have a look at it.

So I'd like to have it so that on the form load it plays and animated gif, then after that gif is done it hides and then shows a different picturebox. How would I be able to do this? Could I use some form of timer and count how long the gif lasts and then use a timer for how long it is? If so how explain a bit.

VB.Net 2010 program .exe on PC with Excel 2007 gives error when cannot find Excel version 14, which is Excel 2010 I have developed a program in VB.Net 2010 which reads from an Excel spreadsheet. It works fine in the IDE on my computer. I built an .msi and executed it on my computer. I get "Error: 53 - Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=14.0.0.0, Culture=neutral,PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified."
The only version of Excel on my computer is 2007, which is version 12.0.6557.5000. The version the error says it needs, version 14, is actually the version of Excel 2010.I have put in MsgBox statements to find where the error occurs.

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.

Problem:I am not getting the cursor (4 arrowheads) for moving the form.I am using the Panel1_MouseHover to display the cursor. Right now if I choose any other cursor then it is working but the same cursor also displays when I hover the mouse over any other control. I want the cursor to show only in the areas of the Panel where there are no controls.How do I show Tooltips for the images? The play,stop,next, previous,playlist,Hideme(with the smiley),volume are all images and not buttons?

If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.

this is my very first posting and I must say I am desperate. I have a VB assignment due in 2 days and I am so lost. I have written a code to draw some graphic, just a basic house, tree, sun etc. I have also written a code to magnify said graphics which were all the specifications of my Assignment 1 part A. Now for Part B I am being asked to extend my program so that: A - My graphic can be drawn using different colour schemes designed by me but chosen by the user B - My graphic or an appropriate part of it can be animated around the picture box if the user chooses to do so. C - Error checking is included.
