Error - System.ArgumentException Was Unhandled. Parameter Is Not Valid
Feb 28, 2010
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)

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 made a program with Visual Basic Express 2008. I got this error message when I try to close my program after running it. (PS: It is a simple code that can login into Microsoft SQL Server)The error message shows the error was caused by the "system.drawing" (Parameter is not valid). Also, I have been trying the code in VBA (Excel). When I tried to close Excel after running my code, I got the same problem (Microsoft Excel has encountered a problem and need to be closed.....) and the error report shows the error was caused by "system.drawing" as well.

I have an error but will explain how i set up my db:Two tables, One is called Area and the other Postal_Code.
The aim is to assign a postal code to the area.Sometimes we add postal codes and sometimes these codes change or need to be deleted.I used the wizard to create the datasets and dropped them on two forms linked to a SQL db.We can Add,Edit,Update & Delete so all is working fine there is no relationship between te tables as they dont need to be linked, I only require the PCode to me added to the Area Table, not any ID or Index etc.
One of the fileds in the Grid on the Areas form is the Postal Code, its set to a combobox that when the user is adding it gives them a selection of postal codes to select from.I get the error when loading the datagrid on the Area form: System.ArgumentException: DatagridViewComboBoxCell value is not valid
This happens only when the postal codes are changed or deleted in the Postal codes table.
I know what causes the error - the dropdown on my Areas form looks for the value in the Postal Code table and does not find it beacause it has either been changed or deleted.Im doing this manually - I go into SQL and remove the postal code data from the record.Then the form loads with no errors.
Q: Is there any way when the Datagridview loads that I can tell it when the PCode does not exsist in the Postal Codes table that it should rather leave it blank and warn the user that there are errors they need to fix befor they can save.

I'm getting the following exception when I try to run up my Winforms app and haven't been able to find a solution to it:
System.ArgumentNullException was unhandled
Message=Value cannot be null.
Parameter name: activationContext
[code]....
I've added a handler for the "unhandled error" event in the applicationevents class but it never reaches that stage and there is no source code running that I can break into and diagnose.
The application was fine until I added a user control (nothing fancy, just a standard windows user control) and then dragged it onto a form in the app (user control and form were in the same application). The application builds and compiles without any errors or warnings but when I attempt to run it up I get the above error straight away.
Does anyone have any idea what it could be or even how I can go about investigating it? I'm a bit stumped on this one as I'm not sure how to investigate it. I removed the user control from the form and then I removed the user control from the application entirely but the error hasn't gone away. In all honesty the addition of the user control might be a red herring but the problem manifested straight after adding it.

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.
