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 recently posted a WIA sample project in the codebank in this forum here : [URL] What I was trying to do is provide a video preview of the webcam video in a window, but I am having problems with trying to pass in the Window Handle. It should be as simple as Adding a reference to "WIAVideo 1.0 Type Library", and then putting in the following
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).

I have a vb.net project which i have inserted pictures and video. I inserted a video clip using the Windows Media Player control and it does work. The issue i have is that i can't move the program to another computer because the pathname for the video will be wrong. I know i could change the pathname when i move it but this is not practical because i need to present this program. Does anybody know how to make the video accessible no matter what location the program is at?
I am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.
So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

I have been working on an HTML editor, and I need to know how to make the "Preview" tab show a preview of the HTML code located in the TextBox in the "Code" tab.
I found that when group by multiple values does not work well with VB.NET, but it works well with C# ,here are my code, is there something wrong with my VB.NET Code? Here is my VB.NET code:
The problem I am seeing is that if i try to do a key preview and i click on a control they form never gets the preview or i am just retarded im not sure which one is the case.. And it really did not seem relevant to put any code in here if you dont know how to do a key preview allready then you probably dont know the answer.
I have an application that requires data be entered, and after entering, a button is clicked to process that data. Clicking the button works just as it should--the data is processed properly. In constructing a test module, I provide a set of data values, followed by:
btnWhatever.PerformClick()
Nothing happens. I have used this syntax for years, and it has always worked flawlessly. I have triple checked everything else and isolated the problem to the failure of the PerformClick(). The PerformClick() is in a test subroutine that does nothing but fill textboxes and labels with default data, then calls the PerformClick() on the button to begin processing. Again, the button works fine, the data is entered as it should be, but the PerformClick() does not fire the click event.

i have a list view of all the files in a folder within my application. is it possible to have a picture box in my app which if the user clicks on a file in the list view that happens to be a image the picture box displays it?
I 've been searching for quite a while to find a way to preview ANY type of file (not just images) much like the Windows XP Explorer does. Eventually I found a solution, using the WebVW.dll (which I had to import to .NET by using AxImp.exe - more info here). This, actually worked like a charm.
However, recently I upgraded to Windows 7, that, in all their greatness, spoiled my hard-earned solution
It seems that WebVW.dll doesn't ship with W7, and even more, it won't register even if you find it, so my solution cannot be deployed.Does anyone have any idea how to go about this?
