Error : Parameter Is Not Valid
May 14, 2012Dim 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.

Parameter Is Not Valid Exception?
Mar 27, 2009I 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.

View 2 RepliesParameter Is Not Valid Error While Drawing A Rectangle
Jun 26, 2011I 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.
Error - System.ArgumentException Was Unhandled. Parameter Is Not Valid
Feb 28, 2010In 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

Error - "Parameter Is Not Valid"
Oct 10, 2010I 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.

View 7 RepliesVS 2005 Passing A Parameter With AddHandler?
Oct 2, 2009From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated
