I have written an application in VB.NET that downloads FLV videos from a website. I can download and save the videos just fine and all works well. Now I would like to have the option to convert the videos to an AVI format and save them that way. Does anyone know how to accomplish this. I was thinking something along the lines of FFMpeg but I don't want to run a seperate process from my application. If I could import a DLL or something and do it that way it would be great. Any help is greatly appreciated!

Me.ofd1.FileName = ""
'OpenFileDialog1.InitialDirectory = Application.ExecutablePath
If Me.ofd1.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.txt1.Text = ofd1.FileName
Me.ReadTextFile(txt1.Text)
End If
End Sub
Private Sub ReadTextFile(ByVal sFileName As String)
Dim oSR As System.IO.StreamReader
oSR = System.IO.File.OpenText(sFileName)
Me.RichTextBox1.Text = oSR.ReadToEnd()
End Sub

You gotta say what it is you are trying to do, and what's stopping you.

So far, all you've got is a little code that reads an entire file into a Textbox. There's nothing that parses the file up into fields and mvoes it into a DataTable that you can use to bind a grid to.
You might want to take a look at this[^] to parse the CSV up into usable data.

Code is :
dim txtdate as string
dim mydataset as new dataset
txtdate=datetimepicker1.text & now.tolongtimestring
I hv filled datagridview at loading time of form.
Now whn searching a record,my code is :
with mydataset(0).tables
.defaultview.rowfilter="[Date] like '" & txtdate & "%'"
datagridview1.defaultsource=.defaultview
end with
but it is showing an syntax error that cannot use like operator between system.datetime and system.string
Now trying this :
with mydataset(0).tables
.defaultview.rowfilter="[Date] = '" & txtdate & "'"
datagridview1.defaultsource=.defaultview
end with
but it is showing an syntax error that cannot use = operator between system.datetime and system.string
what should i do?

The date delimiter in Access is #, IIRC...
Maybe you can try:
with mydataset(0).tables
.defaultview.rowfilter="[Date] = #" & txtdate & "#"
datagridview1.defaultsource=.defaultview
end with

Look at the result of this string operation. I don't think that is what you're looking for nor is it in a format that is usable by the Filter property.

I need an example or code for the following:-
Anyone can help, please?
A data record to represent Car details in Shop
Purpose: To capture data as rows - in 2dimensional array of strings
Ex:
ID Model Colour Horepower
1. Make use of datagridview control without any connection to a database source
2. The data held in the datagridview should be a representation of a small file - then the data would be transfer to a text File on disk
3. Edit the file by reading it back to the datagridview.. the edits must be performed via the control and file recreate on disk
Each row in DGV will be record for the text file - concatenate all string as one before committed to disk
Therefore the single string records is decoded into the fields that match requirement of the original data record design
Thank a lot for help

As the others have said, do your own homework!

Hai!!!
Here I am doing a object oriented program.In that we create various classes in class library.And, we add reference of the dll to the project.My doubt is I have created a new class class Maze.Which will create a maze shape in UserInterface.The content of the maze class is read from a text in the path specified.And, i have created maze using inheriting the cube class.With select the maze file content is read and if it is 'X' it creates cube and it is '0' it end the if statement.And, the File is reading correctly Character by charater.And, Finally I am getting an Exception thrown by Target of an invocation.The code I wriiten are,

You never said what the exception was, so it's kind of hard to pin anything down.
But, glancing through the code, it would appear that you're reading one character past the end of the file. In your Do loop, check for the EndOfFile, not the character count you've read against the length of the file.

I have a main form with a contextmenustrip. I have the contextmenustrip being displayed immediately when the form is loaded. The problem is that the contextmenu is being displayed about a half second before the form is visible. I've tried launching the menu from load, activate, focus, enter, etc. Also tried using suspendlayout. Same result.
Any ideas on how to sync the menu to be displayed when the form is done loading and already visible?

Hello,
I will give you suggestion.See wheater it works...The Contextmenustrip must be visible by MyMouseDown Event only.so, put an If statement in MymouseDown, that has the code this:
If e.Button = Windows.Forms.MouseButtons.Right Then
ContextMenuStrip1.Show()
End If
so, i think your contextmenustrip will be visible only when you click the right button of the mouse.

try the form 'Shown' event
|
|
|
|
|
I had high hopes about this since I missed this method last night, but the result is the same. The menu is displaying about half a second prior to the form being loaded.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

well if all else fails you could use a timer to display the menu a second after the shown event has been triggerd (start the timer in the shown event)
but I'm shure this isn't the best solution, at the moment I can't think of an other way
