Anyone else have an issue using read, It appears when I use read it gives me the correct buys but returns the wrong integer value So I use it and it fills the Array i make with &h10, &h6 but read reutnrs number of bytes returned to 1. if there a better way to go with Vb.net with RS232 I mean really my projet dosent have anything out of the Normal

What's best practice (in VB.Net):
Function GetSomething() as String
GetSomething = "Here's your string"
End Function
or
Function GetSomething() as String
Dim returnString as String = "Here's your string"
Return returnString
End Function
Obviously, neither of these implementations make any sense, but they're just meant to illustrate my point. Is there anything to be gained by using GetSomething itself to store the return value instead of declaring returnString locally and then returning that (does it avoid having an extra string allocated/instantiated - and if so, are there any performance/memory benefits)?
I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

I'm exporting a table of data to CSV format, e.g.:
"COL1","COL2","COL3"
"1","some text", "£232.00"

I have a bit of a strange problem with MySQL that I've never seen before. Basically, I need to enter the same entry into a table x number of times. The Primary Key is auto increment so there shouldn't be any duplicate value problems. However, it takes the last few columns and seems to clump them all into one value and is using that as a key. The error I'm getting back is:Duplicate entry '80-0--2011-06-16-0-1' for key 'idx_mtind you, there is no field called idx_mt. The primary key field is called just ID. And that 80-0--2011-06-16-0-1 is the last 8 columns or so (which you can see the names of in the cols variable) concatenated, which they obviously shouldn't be doing. Also, the first time the loop runs through, the entry goes through, but the later ones conflict with it. I confirmed that this is the problem by changing one of the last 8 columns to a value based on a loop, and that went through with no problems.
Dim cols As String = ""

i am working on an application which calls the COM component of a partner's application.Ours is .Net, theirs isn't. I don't know much about COM; I know that the component we're calling is late-bound i.e.obj As Object = CreateObject("THIRDPARTY.ThirdPartyObject")We then call a method on this COM object (Option Strict Off in the head of the VB file):obj.AMethod(ByVal Arg1 As Integer, ByVal Arg2 As Integer, ByVal Arg3 as Boolean)I am a bit nonplussed that even though this call works, this overload doesn't exist in the COM interop .dll that is created if I instead add a reference to the COM server using Add Reference. The only available call to this method that it says is available is AMethod().

To bypass the stupid "security" bug in outlook I use redemption.safemailitem.Now, this has worked for years, but for some reason I can�t change the adress to which outlook sends the mail. Instead of sending to the adress in the code, it sends to an old adress that�s not anywhere in the code (but it was, ages ago)

I have a problem with strange character.
In mysql this character 💀 cause error Incorrect string value: 'xF0x9Fx92x80'
Samples of these characters are from [URL]
Say I want to analyze data from the web and found some strange character
how to remove this character 💀 ??
The occurance is rare.
In fact, how to know all characters that may be problematic for mysql and remove that? I am not saying escapeable characers. I am saying characters that are neither numeric, alphabeth, or chinese scripts, or punctuation. Characters that's totally bizarre.
How do I get rid of that from a string?

View 6 RepliesI have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"
