I have been assigned to Convert a VB.NET project to C# and I got stuck. I am using a class called RsiOPCAuto, but I don't think that I'll have to go into to much detail into explaining how it works. Let's just get on with my issue.
So basicly what i do is grabbing an object from my class using this code:
public partial class FrmPartialMain : Form
{
RsiOPCAuto.OPCServer oOpcServer;

my code is :

The error is Value of type '1-dimensional array of string' cannot be converted to 'String'.
I have a problem here for converting object of array to string of array in my VB.Net code. The object of array is quite long and contains 6 sets of data here.
Dim varReturnResult As Object
Dim varMapData As Object
Dim StrMap() As String
varMapData = varReturnResult(2)
StrMap = Split(varMapData, vbLf)
I encountered this error "Conversion from type 'Object()' to type 'String' is not valid." when trying to retrieve the StrMap value.
I don't understand why the line final.join etc pops up with these errors!! Value of type 'String' cannot be converted to '1-dimensional array of String' And Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated This is my code.

I've found a lot of other references to this error using Google but I'm having trouble making sense out of how they apply to what I'm doing.
Here's the VBA error I'm getting at compile time: "Function or interface marked as restricted, or the function uses an Automation type not supported in Visual Basic."

I need to do this to every line in a file and save the # five Element in an array. I keep getting (error code 1 Value of type '1-dimensional array of String' cannot be converted to 'String'.)
NOTE: if I change ( Dim Lineoftext(1) to Dim Lineoftextt works) (It does't seem to work with arrays)

I keep on getting a error "object not set to an instance of an object" i am puzzled by this since there are no errors until i run the program. I redim the array. the build is fine. the exception is handled. and the structures and "dims are all global"
So, I'm creating an array of labels. I have labels set up as:
labal1
label2
label3
etc...
I've declared the array as such:
Dim labelArray(5) As Label
Now, instead of assigning the labels one by one to the array (labelArray(0) = label1, labelArray(1) = label2, etc...), I was hoping to use a loop (there will be more than 5 labels). I have something like this, which obviously doesn't quite work:
For i = 0 To labelArray(i) = "label" & i Next
Is there a function that I can use to convert the labelName string to an object, or have vb.net see that as an object instead of a string?
This is something that has been bugging me for a while as it is easily fixed but not desirable.I have a DataGridView that has 5 columns. The first is called ID.In vb.net the following line gives an error "Object reference not set to an instance of an object": dgvJobs.Columns("ID").Visible = False ' ERROR dgvJobs.Columns(0).Visible = False ' OK
Obviously using the name is much better than a hard coded value to reference the column but wondering if there is anything i can do to get this to work correctly?The datagridview datasource is BindingSource control with the datasource being a dataset.

I get an error at the ReadContents(0) = FilePath line saying "Object reference not set to an instance of an object", but the message box shows that "FilePath" holds the file path string.
I have set my datasource on my datagridview to be a subset of rows as follows:
dg.DataSource = myDataSet.testTable.Select("id=" & id)
But I get a runtime error that Operator '=' is not defined for types 'Object' and '1-dimensional array of DataRow' There should be an easy way to do this that doesn't involve creating new tables, etc.

[Code] As you can see, the code in the client side calls a function in the Server that generates an array as output. And this output SHOULD be loaded into the new array that was created in the client side. The case is that it is not allowing me to do that. The blue underlined row gives me the following error: Value of type 'ClientTest.TestService.ArrayOfString' cannot be converted to '1-dimensional array of String'.
I cannot see what is wrong, the function generates the same output type as the new var that is expecting to load it. Why data cannot be 'converted'? And what would be the solution to turnaround this problem? PS: Actually my function is a bit more complex than that and evolves a DB query, etc, but I reduced its code to simplify as the problem is occurring just in the array transfer.
I get the error: "A value of type 'string' cannot be converted to a '1-dimentional array of string'
View 1 RepliesI am using the IndexOf function of the string class to find a specific instance of a string. And based on that I have a logic to do something. Below is the example of what I am doing. The code is in production and is working fine. But for some instance I am getting an "Object reference not set error". Yeah its intermittent.The requestXML is a string of xml data passed in as a paramter to a subroutine. I am fetching the xml string as a form post in a request object. The only thing I could think of getting this kind of error is when the requestXML string varia

I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."
