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

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.

So I have this weird issue where I set a SqlParameter.DbType field = to a SqlDbType.Decimal, but instead it sets it to a SqlDbType.DateTime. I'm going to include 2 screen shots from the debugger one line after the set statement. As you can see when I hover over (just after the execution of that line), it set the param.DbType to the wrong value. I can only assume that the param.DbType has code that incorrectly changing the type. How can param.DbType become a SqlDbType.DateTime when the varable I'm setting it to is a SqlDbType.Decimal? I'm targeting the .Net Framework 3.5.

Here is my problem: I developed one application in VB.Net in VS 2008 Express Edition on MS Vista. I published the application and created the installation setup. Now when I install this application on any Vista machine, it runs without any problems, but if I install it on an XP machine, the installation is clean, but when I launch the application, it ends abruptly without any warnings/error just after the splash screen.
Then to investigate further what I did was that I copied the source project from my VS 2008 Express Edition on Vista to an XP machine having full (VS 2008 Team System) version , and when I try to compile it there (XP/VS2008 Full), I get one error in one of the forms resx file. Incidently this is the same form that gets loaded after the splash screen. So I see there is some correlation between my application ending just after the splash screen and failing to compile the main form of the application. The error that I get reads like: "Invalid resx file. The parameter is incorrect Line 1374, position 5."
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

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.
System.InvalidOperationException was unhandled.

This is the MSDN example for handling the BeginReceive callback.BeginReceive is called over and over until no more data is available, i.e. EndReceive returns 0. However I am finding that the callback is only fired when there is data available.
I'm guessing that the example is simply wrong or refers to expected behaviour in a previous version of .NET, although it says it is for 3.5.So how do I ensure I have received all of the available data?

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.
