Original Code (VB.net): curStyle = curStyle And (Not ES_NUMBER)
Changed Code (C#):
curStyle = curStyle & (!ES_NUMBER);
But it is giving me this error: Operator '!' cannot be applied to operand of type 'long'ES_NUMBER is of data type long.I tried changing it to int, string, etc. All doesn't work.
result = SendMessage(buttonhandle, BM_GETSTATE, 0, 0)
buttonChecked = (result = BST_CHECKED)
Now I want to know whether the bit for BST_CHECKED is turned on or not.
How would I do that?
I can do
buttonChecked = (result % 2 = BST_CHECKED)
Is there a better way?

The interesting thing is, that when I try to shift any number greater than int32 in .net, it yields bad results.. Every number under int32 (2147483647) yields the same results from php and c#.net or vb.net Is there a workaround for this in .net?
Did anyone else read this article under Visual Basic News? I thought it was a very bad treatment of the subject. I especially don't like articles like that when the code they post relies on Option Strict Off.
View 12 RepliesI want to perform a bitwise-AND operation in VB.NET, taking a Short (16-bit) variable and ANDing it with '0000000011111111' (thereby retaining only the least-significant byte / 8 least-significant bits).
View 3 RepliesAccording to MSDN The And operator can act as a bitwise operator OR a logical operator.The only way to know if it is used as One operator or another is, If it is on the right side of an assignment operation? for example x = 3 AND 5. I cannot find any other instances where the bitwise operator would be used instead of the logical operator, are there?

View 4 RepliesI have an abstract user control(baseModule) that has a property that I plan on using a bitwise comparison on to determine what export types are supported by that module. In the designer of a module derived from baseModule, I am presented with a combobox with the ability to just select a single value (Html, Xml, etc.) I would like to be presented with a drop-down checked listbox so I could select which values I want.How can I accomplish this inside of VS2008? I've seen other properties support this.

I'm re-writing some old application in VB.NET to C# and ASP.NET 3.5. Everything is going OK but I have this problem - and, as the database will not be changed, I must find a solution to it.The old app saves the list o desired days (from Sunday to Saturday) in a byte. This is the way it do it:
If chkDaily.Checked Then
daysBitmask = 127 ' This is for a full week

In this 2nd one attributes are being changed, but they're the wrong ones and I can't pinpoint it right off hand.
Edit: What the overall goal of this is that if the user has the attribute checkbox checked then the file needs to have it set, other wise the attribute (if it's present) needs to be unset.
I am trying to combine three Byte values to one Long value, like System.Drawing.Color.ToArgb() does.
I've looked up reference source code to find it and converted it to VB .NET:
Return CLng((CInt(red) << 16 Or CInt(green) << 8 Or blue Or CInt(alpha) << 24) And -1)
It works fine of course, but I don't really understand why alpha shifted by 24 is last, not first (so it would be in nice order 24, 16, 8). I don't really understand bitwise operations a lot. Also, this code snippet works for 4 bytes, which is redundant for me, I need just three bytes and I wonder if Long is still required when bytes are only three, wouldn't Integer do just fine in this case?
So, my question is, how do I rewrite this code to work with just 3 parameters? Do I need to use Long? And, I know this is silly, but is it possible to make byte shifting in order 16,8,0 instead of 16,8,0,24? It's really just aesthetics, but I am awful perfectionist.

I have written a simple VB.net application which saves information to an RFID tag. I am now trying to compress my data. The solution I have come up with involves bitwire operation.Basically I store 2 numbers per 1 byte (0-9, 10 being a period, 12 possibly being a negative/positive flag,13,14,15 unused as of yet).The code I am using basically shifts the byte containing a number left, 4 spaces, then 'OR's it against another number.Therefore 12 is now represented as 00010010. The problem i'm having is decompressing. Obviously getting the '1' back is easy, as I just shift right 4, then grab it. I need to append or remove the last 4 bits.My solution after many headaches was to reverse the bit order, shift left 4, then reverse, then tostring it.

View 4 RepliesIt is a program on which logic programs can be developed, compiled and downloaded into Programmable Logic Controllers. It is fairly big and complicated and the resulting .exe file is about 2Mb. I need to develop the program further now, and would like to use VB.net. When I try loading the VB6 code into VB.net, it changes all the variables of type Integer and String into type Object. It then states all through the resulting code that the default values are not defined. I assume that if defined as Integer and String variables do not need a default value, it would assume them to be 0 and empty. Any ideas why the program changes the variable types during the converstion? All forms start with 'Option Explicit', so all variables are defined.
