View 4 RepliesIsnumeric Cannot Recognize Percentage String As Number?
Feb 16, 2012I have some customized string formats of double values. I need to convert these strings to double values at some point (Note that these strings may contain error messages other than numbers). So I first check if these strings are numbers, and if yes, then convert them to double. Isnumeric works for my first customized string format. But I found that is numeric cannot recognize percentage strings. I wonder why isnumeric understands () but cannot understand %. And what is the better way to convert "(100.00)" and "50%" to doubles other than Cdbl?

Asp.net - Why IsNumeric() Fails On A Number
Aug 2, 2009I currently have this line of code which has been working for the past 6 months:
If IsNumeric(txtProductID.Text) Then
...do stuff
Else
Dim msg As String = "Error!"
End If
All of the sudden, no matter what kind of entry is put in txtProductID (including plain numbers), it fails! Is there reason for me to be going crazy over this?

View 4 RepliesWrong Result From IsNumeric() In .NET?
Jul 21, 2011I have a function in VB.NET that loops through values and attempts to convert it to a decimal if IsNumeric is True,
Dim Value As String
If IsNumeric(Value) = True Then
Rate = CType(Value, Decimal) <--- bombing here
End If
I've found that when the function receives the value 603E43 IsNumeric evaluates to True for some reason and then bombs on the conversion. Why would IsNumeric be true in this case?

View 13 RepliesIsNumeric Returns True For Strings Containing A D Character
Nov 25, 2011I had a strange error in a VB6 app this morning and it all stems from the fact that IsNumeric is not working as I expected. To me this seems like a bug.
This code displays 4.15877E+62 in a message box:
Dim strMessage As String
strMessage = "0415877D57"
If IsNumeric(strMessage) Then
[Code]....
I am guessing that the runtime engine is incorrectly thinking that the D is in fact an E? I think this is a bug though as the exact same code in VB.NET outputs not numeric Is this a known issue with IsNumeric?
IsNumeric Vs TryParse - Make Sure The Data Is Valid
Oct 11, 2009On all my assignments I am asked to make sure the data is valid - only numeric, no empty strings. And I keep wondering which is the best to use IsNumeric or TryParse. When I try both on coding they seem to do the same thing, and I don't seem to find my answer online. Any ideas of why to use one over the other.

Call Plot()
[Code] .....
Which is used to plot bearings. The user inputs a bearing of 0-360 degrees. It works fine if a user say types in "abc" or "/" i.e. anything that isn't numeric. But if a user types in "90/" then it allows it. When the bearing is plotted the keypress is surpressed so the user cant then go back an edit. Is there a quick way to amend the code to allow for this?
Setup DataTableAdapters To Allow For Easy Code Change When Change Server Names?
Feb 20, 2012I'm getting familiar now with using the Dataset Designer and how it makes for quick and easy updates and query of tables. I use to use the OleDB commands and leave the Connection String as a Global Constant so I can easily change it if the server name changes, or if we have to re-direct the .NET to another instance of the database.
But now that I use the Dataset designer I'm concerned that I maintain flexibility and support in the long run. how the Dataset designer works and where it stores it's connection string info? And how difficult that would be to update. It looks like I modify the App.config file, but I'm unfamiliar with this.
What am I getting myself into? It looks like a standard XML file. Is that it?

View 3 RepliesError "E_UNEXPECTED(0x8000FFFF)" When Using CDec/CInt/IsNumeric?
Mar 31, 2010I have build a DLL with COM enabled. In this DLL I have classes that did use the functions CInt, CDec and IsNumeric. If I test these classes from a .NET application then it works ok. But when I called/run these classes from a Win32 application (with COM) then I did get an "E_UNEXPECTED(0x8000FFFF)" error.After some debugging I found out that the problem would go away if I:- replaced IsNumeric with Integer.TryParse or Decimal.TryParse- replaced CInt with Integer.Parse- replaced CDec with Decimal.Parsey.
