System.ArgumentException In Mscorlib Upon Editing In App_Code?
Jul 14, 2011
I am not sure if this is how things are supposed to be, but during development, I might like to change a line of code in a nice little helper class.This throws numerousA first chance exception of type 'System.ArgumentException' occurred in mscorlib.dllThe site restarts and I have to navigate back to where I was to see if the change worked.It is massively time consuming, and I hope there must be some option to prevent this. Is there?

I have the following code running, the first time I change the selected index, everything runs smoothly. However, if I try to change the selected index again, nothing happens and the subcategories combobox values do not change.
Private Sub cboMainCategory_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboMainCategory.SelectedIndexChanged
'* make sure the combobox is fully loaded

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.

We have developed a mail server. It's working fine on all Windows7 machines. But on XP machine, it gives the error of system.fileloadexception and file which is shown in error message is mscorlib. And one more thing is, this error message is not coming on all the XP machines. We have searched a lot on google to resolve this problem. And many developers have faced this problem. But we have not found any solution.

I wrote a POS system a few years back, about 5 Then updated it about 2 years there after, so it has been running without problems for about three years now.All of a sudden of saturday, The following error comes up, System.outofmemory exception in mscorlib.All the system does is run the POS. Its not connected to the internet, nobody installs anything on there.And to make it worse, I now specialise in web strategy, and am a 'bit rusty' when it comes to vb.net applications.

If i run the program more than 2 hours i get an exception of: "System.OutOfMemoryException occured in mscorlib.dll" One of the suggestions is , if you are creating an array make sure the size is correct. Here is my Array:

I have two Datagridviews, Datagridview1 populates from and excel workbook the user selects. After that the user does a verification on the data. The Requirement I have is for the two grids to mark any records in yellow that are the same so the user knows what needs to be done.
I did the code to match the Cell Contents as there was no other way.Datagridview2 is the sartting point, the value in colum 9 is what needs to be found in Datagridview1 so i loop through the rows, colums by column, It finds the first lot and marks them yellow but then stops with the error. It does not run through all the entries.
My Sample code:'Button click event calls te public sub Datagridview2RowCounter
'Declare Current row position of grid 2
Dim Datagridview2CurrentRow as integer
'What text it should find and mark
Dim BookData as string
[Code]...
This is basicaly what i did but it stops after the 7th or so time it passes through all the code. I have more that 3500 rows of data to verify each time the workbook is opend, that is why i need to mark the Cells in yellow so i know what has been done.im stuck, everything works fine in the whole app, from importing data from excel into datagridview to the marking of other fields for some other reason, This is the ons that does not want to work.

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've tried pretty much everything to solve this problem (except what works, obviously) and almost worn out Google, so now I'm giving this forum a chance. Basically I'm making an application which needs to map column names in an excel spreadsheet to fields in a table (TableB) through a data transfer setup table(TableA); To make this work as planned, I need to compare a value in "FromField" in TableA with headers/column names read from an excel spreadsheet into a list of strings, and if they match, map "FromField" against "ToField", prior to importing data from the spreadsheet. The column names that don't match with "FromField" are to populate a combo box in the FromField column in my DataGridView.
PROBLEM: I get this to work fine as long as I don't handle case differences (e.g. "FieldToBeImported" in Field1 vs. "fieldtobeimported" as header in spreadsheet), but this prevents matching words with case differences to be mapped, and leaves it to the user to manually map fields that should have been mapped automatically. However, if I make a ToUPPER copy of the List Of String that contains the MS Excel column names and compare them to a ToUpper version "FromField" data, I get the error message from the topic:
"System.ArgumentException: DataGridViewComboBoxCell value is not valid"A little explanation on DataGridView2 before diving into the code: Column in index 0 is a DataGridViewComboBoxColumn added in code, where matching fields in column 0 and 1 are mapped, and non-matching fields are populated in the combobox.Column in index 1 is "ToField" (TableA as source), Column in index 2 is "FromField" (TableA as source) and is hidden in runtime.

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

Now I have a check when dataset is filled i checked is there any row ? if yes then it do the rest of work otherwise agin call it self to search for the record...ECURSION.. In Case of records with status zero , It works Fine But in Case of no records Which have status zero it recursively calls itself For approx 1.5 mints and then throws The Exception That " System.StackOverflowException occured in mscorlib.dll at line "DataAdapter.Fill(Dataset,Table)" . I have no Idea what to do with this ..
Eventhough I have Encloesd It in Try...Catch Blocks but It didnt Cath It .. I serached The Internet and msdn social help for it and i found that it occurs most with infiniteloop or Infinite Recursive calls. i know it is due to my recursive call to the SelectData Function But i have no option without it?And One thing more that this project i mean the exe of this project is concurrently runs with another project Which add data to the databse about Filename Filepath and status =0 for Fresh entry..

Trying to read key "HKLMSOFTWAREPoliciesMicrosoftWindowsWindowsU pdateAU" value "AUOptions" and get the following : A first chance exception of type 'System.Security.SecurityException' occurred in mscorlib.dll Error occurs in ReadRegistry key SOFTWAREPoliciesMicrosoftWindowsWindowsUpdate AU : Requested registry access is not allowed. This occurs in my vb.net application when application is run under an account called OPER in the USERS group. The application :
1/is on my PC's hard drive, its not a web app or on a network share
2/is launched via a desktop click
3/ has a manifest specifying executionlevel "AsInvoker"
It does not occur when the Application is run as an Administrator. It does not occur if I read the value with a non .NET program when logged in as OPER whch makes me think it is a .NET problem not a registry permissions problem. Examining "Effective Permissions" shows that my OPER login has query value permission.I need the application to be able to read the key like the non .NET application while running at USERS level.
