my youtube video downloader app was working but it stopped working due to Dec-2012 YouTube changes. my code is unable to load the download format.
Currently, the video info loads but the application is unable to load the available download formats and download the video.

I hope anyone is able to take a look at the code and see what's wrong?
I think the error is in here:
It's my first question in this forum...just read a response to another guy that helped me a lot.
I am working for some project in my university and they asked me to make an application in vb.net. Then I had to save different data for every user in order to check his own work, so I used SQL management studio to import some information to arrays there.
The big problem that I face now, it that they would like to work this project online, so as users can open it through their website. I have no idea if all the code I wrote in vb.net and connections between VISUAL studio and SQL studio could be transfered online ! Maybe I could convert most of them so as to run the project online.
Can anyone help me ????
I would really appreciate every advice or help !!! I am searching for a solution so as not to lose my project( that I almost finshed ).
Aw, sorry for using C#-terminology; it's called "Overridable" in VB.NET.
We have several programs with multiple forms that we need to do this on.
Can you please give concrete examples?
Take an empty form, and modify it like below;
' This call is required by the designer.
' Add any initialization after the InitializeComponent() call.
Next, change your existing form to Inherit from the BaseForm like below;
PublicClass Form1 : Inherits BaseForm
This would give you a method that's called when the form is constructed (just like InitializeComponents), and give you the option to override it's implementation for a specific form;
I wonder why you wouldn't just call your customized initialization from within the Load event in your source code for each Windows Form. Doing so, you don't have to touch the Windows Form Designer generated code file (*.Designer.vb).
Your code is essentially correct but what you haven't done is to read the type of data stored in each name-value pair so that the correct cast can be applied.
The raw data obtained from GetValue(valueName) is typed as Object and the ToString() conversion gives a correct representation in most cases, the exceptions being when the actual type is an array (REG_BINARY, REG_MULTI_SZ)
The technique is read the type via GetValueKind(valueName) and then apply a cast to the Object returned from GetValue(valueName). The incomplete method below shows the basics and in your case formatting the values ready for display should be done in the gaps left as "do something appropriate".
PrivateSub InterpretValue(rawValue asObject, interpretAsType as RegistryValueKind)
' REG_BINARYDim byteArray AsByte() = DirectCast(rawValue, Byte())
' Do something appropriateExitSelectCase RegistryValueKind.DWord
' REG_DWORDDim signedValue32 AsInteger = DirectCast(rawValue, Integer)
' Do something appropriateExitSelectCase RegistryValueKind.QWord
' REG_QWORDDim signedValue64 AsLong = DirectCast(rawValue, Long)
' Do something appropriateExitSelectCase RegistryValueKind.Unknown, RegistryValueKind.String, RegistryValueKind.ExpandString
Dim stringValue asString = rawValue.ToString()
' Do something appropriateExitSelectCase RegistryValueKind.MultiString
' REG_MULTI_SZDim stringArray AsString() = TryCast(rawValue, String())
' Do something appropriateExitSelectEndSelectEndSub
Thanks for the explanations. I understand that I should be considering the data type. I can change my code accordingly. But what about the "Last Write Time" information that is displayed in the exported text data for these keys? How can I access that? My goal is to capture the History of each USB device that was used in the system, with dates and times. I'm assuming that the Last Write Time on the exported text will give me this information, but I don't see how my code, even with the data type considerations, will access that.
The .NET RegistryKey exposes a small subset of the full Windows Registry API and to get the LastWriteTime requires the Windows RegQueryInfoKey function. Microsoft made this really difficult prior to .NET 4, as the RegistryKey class did not expose the operating system registry key handle.
With the restriction of .NET 4 it should be a simple matter of using P/Invoke to call RegQueryInfoKey with the twelve parameters set correctly! I haven't done this but most of them are optional, so can probably be set to null or IntPtr.Zero.
If you have to work on a lower (lesser?) version of .NET then I don't think this will be an easy task as there is no facility to exchange handles between the .NET RegistryKey class and the native Windows functions. I think the only option would be using RegOpenKeyEx to get the handle and then call RegQueryInfoKey.
I designed my report using the Report Viewer control. The data on my report is not tabular. It is a fixed-field form that spans several pages. I set the data source to a collection of an object that I developed and all the data for the report comes from my collection (which will always only have one item in it).
The report seems to be working fine, I setup a header and footer. When my code refreshes the report, my data is displayed nicely on the report as i designed it. However, when I convert to Print view, the report seems to be inserting page breaks while rendering. my nice little 4-page form becomes a 10 page report with page breaks occurring on every other page and some extra at the end.
What can I look at to determine why these extra page breaks occur in the rendering process? I thought it may be page layout related, so I changed the margins to all zeros and still see the additional page breaks.
Also, another thing I noticed is that when I added the footer, the footer height is about 2.5 inches and the designer will not allow me to change it.
