Combining A String And String Variable Into One Variable
Apr 4, 2009I am trying to insert a string variable inside of two strings, and make a combined string.

I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
View 12 RepliesUse CType To Change An Object Variable "obj" To Custom Class That Reference Using A String Variable Like Obj.GetType.Name?
Feb 9, 2011The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

View 1 RepliesSorting - Sort List(of String()) Using A Variable Index Into String() As Key ?
May 30, 2012I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String())
Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex)))
End Function
When String Variable Was Empty String First One Returns 'nothing'

View 1 RepliesCan't Load A String Into A String Variable?
Apr 12, 2009I am using the MODI DLL (Microsoft Office Document Imaging) because it has an OCR engine. That's working fine, but I'm having trouble capturing the resulting text into my own string variable (weird, huh). Modi has the result stored in the following Modi string variable:
img.Layout.Text
I've tried three ways to capture this value, only one of them works (not the one that I need to work)
(1) Dim txt as string = img.Layout.Text 'fails
(2) MsgBox(img.Layout.Text) 'fails
(3) M = new Msg(img.Layout.Text) 'succeeds
Method 3 (the only one working) is a custom msgbox I built in VB.Net, and it accepts a regular .Net string variable. I need Method-1 to work. The error thrown is this:
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt." I even tried it like this:
(1) Dim txt as string = img.Layout.Text.ToString.Trim
Here's the complete code:
Dim doc As New MODI.Document
doc.Create("C:VCR.tif")

Dec 13, 2011If I try to put a string into a Boolean variable such as this:

With Option Strict On I get an error and the suggested fix is to change the second line to:

This is fine, But - what are the advantages / disadvantages of doing this instead:

String Variable From My.settings?
Apr 21, 2011I'm going to describe what I'm trying to do and then what I'm doing in hopes of making this as clear as possible.I'm trying to create a way of having data avaialble to the application that could be changed in the future and not have to recompile the code.Normally I do this for my connection strings incase something changes, this way I can just change the file and I'm good.however in this case I'm trying to store a long string variable that contains something like(including all " in the string) "Dear " + emailRecp + vbCrLf + "Thank you for buying our product...."
Now when I do this as part of the code with something like strMessage = "Dear " + emailRecp + vbCrLf + "Thank you for buying our product...."when I look at the output from this it looks like (which is what I want):
Dear Mr Smith
Thank you for buying our product....
however when I do strMessage = My.Settings.purchaseMessage (even with .ToString()) the output looks like Dear " + emailRecp + vbCrLf "Thank you for buying our product....how to do this in another manner that won't affect performance.I have also tried to trim the " from the first and last char positions and no luck.
