Parameter name: index '6' is the number of tabs i had open.Here's the bit of code i use to create the tabs with the browser in it:

Dim data As Byte() = DirectCast(sdr.Item("Image"), Byte())
Dim ms As New System.IO.MemoryStream(CType(sdr.Item("Image"), Byte()))
PictureBox2.Image = Image.FromStream(ms)
After reading many forums and trying the different examples, when I try and load my image from the database I get the "Parameter is not Valid" error.Im using VB 2010, SQL Server 2008 R2, and the data type is Image. I do not have access to the source code that is used to save the picture to the database, just access to tthe data in the db.The code I have included is the code I use to retrieve images from my db which stores the pictures as Image.

I have made a program that lets you select an area of a picture and then crop it, I am having problems while drawing the rectangle that shows which area will be cropped, following is my code.
[CODE].............
This is declaration of all the variables that I am using.
[CODE].............
Over here I send the graphics handle of the "canvas" control (which is just a picturebox) to a higher level, so I can use it later.
[CODE].............
Over here I get the starting position for my rectangle
[CODE].............
This part is supposed to draw the rectangle, as I am moving the mouse over the Canvas control, but I get an error where the rectangle is being drawn, I originally thought that the problem might have been with the fact that as soon as I begin moving the mouse, the CropWidth and CropHeight variables are at zero, and that is causing the invalid input error. So I made it that it would not draw the rectangle until it reached a minimum size of 4 x 4 pixels but it still does not fix the error, I debugged to see if there was a problem with the values of the variables, but they all seemed fine, I even tries doing this CanvasGraphics.DrawRectangle(Pens.Red, 20, 20, 20, 20) so as to eliminate the factor of the wrong values, but still the same error.

In this screen I want to let the user decide which elements are on shown on a label. When I hit the update button (BDUpdate_Click; see below), it first checks whether the Barcode sample text is empty. Afterwards I want to invole the refresh of the label preview. The strange thing is that the first time it works fine, but when I alter the sample text and hit the button again, I get the Error "System.ArgumentException was unhandled. Parameter is not valid." The error points to the DrawSting function in the LabelPreview_Paint Sub
Dim BarcodeLabelUpdate As Boolean
Private Sub BDUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BDUpdate.Click
If BDBarcodeSample.Text = "" Then
MsgBox("Please enter a sample text", MsgBoxStyle.Information Or MsgBoxStyle.OkOnly, ProgramTitle)

The error is: Parameter is not valid."
By the way my program has 25 forms.

I am getting a "Parameter is not valid " error when reading a value from an Image property and I don't know why.
Writing to the property works just fine (MyControl.EditImage = PictureBox1.Image) .
Reading from the property causes an error (PictureBox1.Image = MyControl.EditImage )
The Property looks like:
Private mNewImage As Image
Public Property EditImage() As Image

I'm trying to make a Tetris game in VB 2010. I am having some problems with a function I have written that draws new squares and fills them with the colour needed. Here are the details of the error:
System.ArgumentException was unhandled
Message=Parameter is not valid.
Source=System.Drawing
StackTrace:[code].....
The line g.DrawRectangle(Pens.Black, lngX, lngY, 24, 24) is highlighted as the error. 'g' is the graphics of the form and lngX and lngY are the predetermined coordinates of the shape as long variables.I have researched this error but I couldn't understand Microsoft's explanation, and no other threads applied to my case.

I have been trying to learn vb.Net for about a year now, but with other work getting in the way, my progress forward is moving, but not as fast as I would like. So I am hung up on this issue which seems like it should be a no-brainer but it still does not make sense, and I can't find any clarification on it.
With the
With MyPen
.Color = Color.FromArgb(LineColorVALs(7, SearchIndex1, SearchIndex2))
.Width = LineWeights(7, SearchIndex1, SearchIndex2)
End With
The array "LineWeights()" is declared as Integer and the values of the indexes are correct. This leads to an integer value of "1" coming out of the array and into MyPen.Width.
The ".Color" line executes OK, but I get the error, "Parameter is not valid." at the ".Width" line. I have tried declaring LineWeights as Short, too, but same problem.

I get this error from my application, but not in the development environment (VS 2008). I created an installer package and have installed it on two different XP machines with no problem. However, on a Vista system when the application runs code to generate an image I get a "Parameter is not valid" exception. I have no clue what could be causing this given the circumstances. To generate the image I am creating a bitmap with a valid size and simply creating the graphic. Since I can't repoduce the error in VS I don't have a way to troubleshoot this.

I am using VB.Net 2008 Express and trying to build a favorites list for a webbrowser I am working on.I get an invalid parameter error on the line that reads favicon = image.FromStream(stream).[code]the urls are stored in an array after they are taken from an xml file.I checked the url that was being used when the error occurs and it seems fine. I can even navigate to it in IE.The error I get is that "stream" is an invalid parameter, at least that is where it points to.It also shows that stream is a type System.NET.ConnectStream.Stream was originally set to System.IO.Stream.I don't know if this is a problem but it processes several urls before it gets to this one.I am wondering if this may be a permissions issue and the site is blocking the WebRequest or if it is something else.

Visual Basic 2008 rookie question. I am getting the error message 'Error 1 The item "objDebugCIT163Lab1Cdrb.WeatherReport.resources" was specified more than once in the "Resources" parameter. Duplicate items are not supported by the "Resources" parameter.CIT163Lab1Cdrb'when I debug. I am familiar with Visual Studio 2008 having used it for my previous C# course.

The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...
