Exclamation(!) Operator Used On A Number?

Jul 18, 2011

I'm looking at inherited code and I found this in a vb.net windows form:New System.Drawing.SizeF(6.0!, 13.0!)My question is, what is the significance of the ! (exclamation) operator here? Most of my searching for the exclamation operator ends up returning recordset format or the ! gets ignored in the search and I get hundreds of unrelated items.

Forms :: Red Exclamation Mark In DGV Bound To SQL?

May 15, 2011

In my application I have bound a datagridview to a SQL2005 bindingsource.I really had to change a database field (more length allowed) and now de DGV displays red exclamation marks and states: 'Colomn 'password' exceeds the MaxLength limit'. (the 'password'-colomn isn't even displayed, but that's a sidenote).I tried different things but can't get rid of the exclamation marks. how I can manage this. I really don't want to create a new DGV, because there a lot of code and stuff involved.

Possible To Use Exclamation System Event To Validate Data Capture?

Aug 23, 2010

In a Windows XP Pro environment, my system uses a mainframe emulator in a window in which a scanning application is running. The data populating the mainframe app comes from various instruments, scales, barcode scanners, etc.. The data inputs are captured by a winwedge type RS232 data aquisition software.

When all the data is processed correctly, the mainframe application sends an "operation completed" message and creates an exclamation system event associated with a specific sound to inform the user.

My goal is to create a MS Access application that would use the Exclamation system event to validate writing the barcode that was just read to a database without further querying the mainframe, creating a local database. I only want to write the barcode when the mainframe application completed and therefore played the sound.

Error: Option Strict On Disallows Operands Of Type Object For Operator '='. Use The 'Is' Operator To Test For Object Identity

Jan 27, 2010

I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:

If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then

It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.

Option Strict On Disallows Operands Of Type Object For Operator Use The 'Is' Operator To Test For Object Identity

Apr 6, 2012

I need to write an interface to get data to/from our data files.

We have a low level class that holds field values for each record read from the files.

This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).

These values may be any of the standard value types (integer, date etc) or a string.

Either value (DBValue or CurrentValue) may be null if not defined.

I have written the class to manage this data which works fine while option strict is NOT on.

But we have an office policy of having option strict on all the time.

When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."

Question, how should I change the following code to handle option strict on ...

This is all running on Visual Studio 2010

Pass In An Operator?

Jul 4, 2010

Is there any way to pass in an operator in VB.NET? I'm looking to reduce my lines of code and for two functions there is literally only an operator that is different.For example, I have two functions, Darken and Lighten. I'd like to get to a single function with as little code as possible. The only difference are Greater Than and Less Than operators.

Function Darken(ByVal clr1 As Color, ByVal clr2 As Color) As Color
Dim newR = If(clr2.R < clr1.R, clr2.R, clr1.R)
Dim newG = If(clr2.G < clr1.G, clr2.G, clr1.G)

[code].....
