Why do i keep getting "Keyword not valid as indentifier" error in Declare statemens even after importing system.runtime.interop?
View 4 RepliesPresently working a tutorial in visual basic 2010. I have encountered the error " keyword is not valid as an identifier" I have read the definition of an identifier in the beginners section. Although I undertand the definition of an identifier I still am not sure of it when looking at a line of code. The tutorial gives an analogy but does not show examples of identifiers as they would actually apprear in a coding project.
View 3 RepliesI try to run this code in visual studio 2008 and receive error msg: Keyword does not name a type and name objClass is not declare
CODE:
Dim
objMyClass As New MyClass = ("Hello World")
Console.WriteLine(objMyClass.ToString)
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
Private Sub BDUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BDUpdate.Click
If BDBarcodeSample.Text = "" Then
MsgBox("Please enter a sample text", MsgBoxStyle.Information Or MsgBoxStyle.OkOnly, ProgramTitle)

I have that so far. It was working great for the names part until I attempted to do the level part, now i get the following error:
System.ArgumentOutOfRangeException: InvalidArgument=Value of '1' is not valid for 'index'.
Also at the line where i use a goto statement to go back to the beginning of the loop, is there any way i can do that without a goto statement? Like a second loop statement or something?
I get Keyword is not valid as an identifier error on this line
Private Sub Event _service_GetReleasesForProductCompleted(ByVal Sender As Object, ByVal e As EventArgs)
Where as I want to Raise an event [set up events].
I tried to follow this method from microsoft i added the whole code to a module and tried to call EncryptFile in a form

MsgBox("tada!")
End Sub

I get an error: Error 1 Operator '=' is not defined for types 'System.Drawing.Image' and 'System.Drawing.Bitmap'.
I have also used 'is' instead of '=' but that doesn't work either.
In the following code all goes well until the .Sort line. Then I get an error which says, "The sort method is not valid. Make sure it is within the data you want to sort and the first sort by box isn't the same or blank."I've tried various permutations to deal with this exception, all to no avail. The Range is Selected ok and the Excel data are pasted from the clip board ok. Then I get the error and no sort occurs.

System.String is a class type, but why we can use it without instantiate it with New keyword?
For example:

No new keyword being used at all?

I have a VB file that imports System.IO, but only uses it is a couple of places.My co-workers and I were wondering if there is a small performance boost if we just use System.IO explicitly were we need it (IE., System.IO.MemoryStream) instead of importing it.

My app downloads multiple files, and its limited to 2 connections. Now I've read you can change this, by adding the following in the app.config file:

And that does work, however I would like to hardcode it in, rather than use app.config file.
I've tried (importing System.Net.Configuration):

View 4 RepliesI have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default.
I'm having to either place an Imports System line at the top of each code behind, or preface everything with System, which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default.
I've already checked to see that WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config contains the <add namespace="System"/> line--it does. That was my best lead.
I have references to several namespaces within the System namespace in the <assemblies> node (e.g. System.Design, System.Web.Extensions of my website's web.config. There is no <namespaces> node. This has not been changed recently.
Where is directoryentry, directorysearcher, searchscope, etc.?

I declare my dates as the following in my code:
Dim DeliveryDate as Date
But i am now trying to declare time however i keep getting an error because i cannot get the type correct. I tried the following but get the following error: "Conversion from type 'Timespan' to type 'integer' is not valid".
Dim DeliveryTime as DateTime
Dim DeliveryTime as Integer
In my database the DeliveryTime type is set to Time(7) so i would assume there should be 'Time' which i could use to declare it, but there isnt. What is the correct type i should be using?
Here is my exact code. There error is Input string was not in correct format:
GraphDate4 = String.Empty
DeliveryProducts = "{ name: 'DeliveryProducts', data: ["

I've got a GridView. My SelectCommand in the code works if I copy and paste it into SQL Server Management Studio. It executes fine.If I run the page and click Edit for any row I get the error:
"Incorrect syntax near the keyword 'IS'."
I've tried to see what's going on using SQL Server Profiler. Here's what the SelectCommand looks like and what SQL is receiving...
SelectCommand from supplies.ascx
SELECT some stuff FROM here WHERE (this IS NULL) and (that=1) ORDER BY this DESC
SQL Server Profiler reports
SELECT some stuff FROM here (this IS NULL) and (that=1) ORDER BY this DESC

My app fails at this line of code:
Dim objConnection As New SqlConnection(Application("ConnString"))
My connection string is: [Code]. I googled this problem and the solution for it was having a malformed connection string where the "provider" was being specified when it shouldn't have. Example conn string: [Code]. I'm not specifying the Provider so I think I have a different problem.
