Dual Screen Video Player With Windows 7 Thumbnail Preview?
Aug 25, 2010
I try to create a dual video player with VB 2010.
With that I have 2 forms, 1 main form (with all the controls and it should contain a preview screen of what is being displayed on the second form.
And a second form (with a windows media player component).
Now the main form should have (as told) a preview screen of what is shown on the second screen, I want to know if it is possible to have is as the windows 7 taskbar thumbnail (when preview the mediaplayer).

One of the things my VB.NET program does is play video files using the Windows Media Player component that comes with VB. My program also switches the WMP component to full screen but once in a while the form will be on top of the full screen video. I am hoping that you fine and knowledgeable folks cat this from happening. The problem occurs when the next video file is played automatically. I'll do my best to post a bit of code but since I don't have much of an idea what might be causing this I'll just have to guess. The project has gotten quite large over the years I've been writing it and if any more code ito post any or all of it, though I'm sure no one would like to go through all 1771 lines of it.

I have a VB.NET application that uses the AXWindowMediaPlayer ActiveX to embed mpg videos to my application. I have used the Play/pause/stop Ctlcontrols a lot but now i am stuck as i needed to change the video size of the playing video from 100 to 200% hence my Questions:- How can i by code change the video size of the video being played? by Video size i do not mean the control's size.. but the Video being played inside it. for example, i could want the videos to play at 200% and not at 100%.- Is there a way to check the dimensions of the video being played so that i can by code change the video size if required as per the video.

I am trying to get this code to re-size(by a percent) the pdf thumbnail it outputs(which needs to be initially scaled down to 15% of the size of the original pdf document size).Currently, the code only adds the two dimensions as pixels, then renders the image, and draws it into a PictureBox.The code uses Ghostscript as you can see. The problem I am having is getting the dimensions of the PDF file. How can this be done? The code will be posted below:
Imports System.IO
Imports System.Drawing.Imaging

I have a button btnRegEx that when pressed shows a ContextMenuStrip, similar to the '>' button in the Find/Replace dialog in Visual Studio when you are using Regular Expressions. I have a ContextMenuStrip cms which I show using its Show(x,y) method.
At first I was simply setting x and y (the location of the ContextMenuStrip) to some point next to the button, but I noticed that when the button is close to the edge of the screen it goes off screen. I wanted to prevent that so I built some logic into the x-y calculation. When the ContextMenuStrip width is larger than the 'remaining space left' I simply show it more to the left. Same for its Height of course. I am using the Screen.GetWorkingArea(point) method to determine the 'remaining space left'. As I understand it, it returns the working area closest to the point you specify (to which I pass the button's location).
As long as I stay on my first monitor, it is all working perfectly fine. The problem occurs when I move the form to my second monitor. The contextmenustrip is still showing on the first monitor for some reason...
Here is the code I am using:
vb.net Private Sub btnRegEx_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRegEx.Click
Dim p As Point = PointToScreen(New Point(btnRegEx.Left, btnRegEx.Top))
Dim x, y As Integer
[CODE]...
I have noticed that when I click the button when the form is on the second monitor, the buttons location (p) is calculated with the first monitor's top-left corner as (0,0), even though it is on the second monitor. This way, the GetWorkingArea function returns something like 1280, while the buttons x-location is something like 1700... So, how do I get the buttons coordinate relative to the actual screen it is on, rather than the entire dual monitor screens as a whole?

The preview on my program doesn't show how I would like it to, sometimes it's blank or not big enough for the whole screen, and other things.
I have 3 forms, one is of controls, one is a full transparent form that is just the outside edges with a blank middle, and one of is the background. Reason for this is setting background transparency, and the transparency(opacity) of the top bar of the form, so it will be transparent like vista is normally in xp.
I want it to show always the full form live view on the preview and I am not getting it to work with my 3 form as one form type program, but it works as expected with one form only, but I don't want this because I want individually set transparencies.

Can anyone provide some details on a way to have a thumbnail image of a random file appear in a panel on a form? I'm working on a project that requires this functionality when a user clicks on a item in a checkedlistbox. This way users can auto-preview a file. All code that I found applies to actual image files, so I'm getting "Parameter is not valid" errors when attempting to create a bitmap thumbnail of a text file. Would a printpreview control work?

I am working on a custom bulletin board system for my company. The idea is to have a program running that displays a full screen bulletin board on many monitors around our facility. I wrote a VB client that pulls from a server and displays a single board perfectly - I am wondering how to expand this.

I have an application which is supposed to convert a video via DirectShowSource.I have a checkbox which enables a button called "btnviewcrop" which shows a new form called crp.vb for cropping/shearing pixels off the video.
Now, I have a Panel1 that I want to set as the owner (the video drawing surface) but when I set it to open, the application crashes (Error: Object reference not set to an instance of an object.) and I do not understand how to fix it.

I have been writing visual basic and vb .net applications for years and have come across this problem with the timer component under Windows 7 32bit on dual core Intel processors. This problem only occurs with Windows 7 running on a dual core processor, single core and under the virtual pc on any processor works.
I have attached a test program to show this problem. The program uses 2 timers to count down to 0. It does not matter what type of timer component I use system.timer.timer or system.windows.forms.timer. I read the system.timer.timer may fix this problem so I changed the program to use it but it did the exact same thing. Left it in anyway.
The program: Timer1 is set to a number of ms for a given amount of time say 150000 for 150 seconds and started. The timer will expire correctly. At the same time a second timer Timer2 is set to 1000 ms for a count down display to 0. Timer2 fires and the count is updated. This happens and everything looks fine. When Timer1 fires I disable timer2 so it will stop counting down. Timer2's countdown is at 2 instead of 0. It is firing slow. If I increase the value of timer1 to say 500 seconds timer2 is behind by 6 seconds. These amounts are the same for the 2 very different computers I ran this on but both are dual processor systems running Windows 7. The exact code works correctly on Windows Xp on the same processors and works under Windows 7 on a Pentium 4 system.

After I upgraded from Windows Xp to Windows 7 on any dual core cpu machine my programs that use a simple timer function run incorrectly. The program works with the exact same hardware under Windows Xp and Windows Server 2003. I am using Visual Studio 2005 to write .NET Visual Basic programs that use 2 timers to count down. The first timer, timer1, is set to a value say 150000 ms (150 seconds). The second timer, timer2, is set to 1000ms (1 second). Both timers are enabled one right after the other from a button click event and begin. The timer2 routine running every second updates a label counting down the seconds. When timer1 fires it disables itself and exits. Timer2 also checks to see if timer1 is still running if it is not it will stop. Under Windows Xp and Windows Server 2003 the resulting count in the label is 0 when timer2 detects timer1 has finished. Under Windows 7 when timer1 stops timer2 is not at 0 it is 3 for 150 seconds and gets larger the more timer1 is increased. It appears to me timer2 is not being fired every 1000ms as it was under Windows Xp.
I have included the Visual Basic code below. If you want to test it just run Visual Studio and create a new project. Put the buttons, numericupdown, and labels in your form and past my code into the correct buttons. I have used these type of timer events for years without any problems unit Windows 7. Windows 7 on a single core Pentium 4 with hyperthreading turned on works fine. Windows 7 on a dual core E6500 fails, Windows Server 2003 works.
