Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
[Code]...
I have :
Dim con As New OleDbConnection(My.Resources.ConnectionString)
// Give exception = Format of the initialization string does not conform to specification starting at index 62.
When I substitute the actual value of the Resource, it give no exception :
Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""")
The value of ConnectionString in Resources :
<data name="ConnectionString" xml:space="preserve">
<value>Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""</value>
</data>
I don't understand why is this happening ?
I think this should have been replaced even before the compilation process..
Then why is it giving exception ?

An argument exception is thrown when attempting to use PropertyInfo.SetValue to set the value of a property in my business objects.The argument is thrown because of wrong data type, even though a valid cast could be made.Is there a way to dynamically cast the object type into the underlying PropertyType of the PropertyInfo object without having to test the FullName property explicitly as show below?
Select Case prop.PropertyType.FullName
Case "System.String"
prop.SetValue(obj, tbx.Text, Nothing)

I have a little piece of code which saves a certain Bitmap to a JPG image. The Bitmap is "composed like this" ( Ppiechart is a picturebox):[code]So After it is declared I start to do some drawing on this bitmap. And then I want to save it like this:[code]So this saves the image. But the problem is that the background of the image turns black when I open the file on my PC.The background of the Bitmap in the program itself is white. So does anybody have an idea what may cause this? Do I have to declare a color for the "mybitmap"?

in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty
Dim wr As Alvas.Audio.IAudioReader = Nothing
Dim fs As IO.FileStream = Nothing
