I can't seem to get this to work. I am just a novice plugger and do some of these forms for my work occasionally. I am assigning a textbox result to a variable. I then want to use that variable in a path string i.e. ("c:some stuffvarname") but the variable looses focus once placed inside the quotes.
View 4 RepliesI am concatenating a variable onto a path(string), i'm using a message box to display this for testing purposes, I can see that the variable is starting on a new line, which in turn when i try to open the file it doesn't recognize that the file exist...
Dim Path As String = "C:UsersstefanDesktopUni WorkYear 4ProjectsProject SelectionProjectProjectinDebug"
Shapetext = clickedShapes.Item(nextShape).Text.ToString.Substring(0, clickedShapes.Item(nextShape).Text.IndexOf(" "))
MsgBox(Path + Shapetext + ".txt")
I'm looking for a way to search a string variable for two words and copy the text in between them into another variable. This needs to be done as many times as the match occurs.
View 3 RepliesI am trying to allow my VB.NET EXE to have a variable defined by the run command. The problem is I have no idea what the terminology would be for this type of run.
For example - the shortcut is set to do "myexe.exe debug" This would set a variable to "debug" which on execution my app knows to enable a debug mode.I've done it in batch scripts before - it just enables the "%1" variable or "%2" based on the location (e.g. test.bat hello world - hello would be %1 and world would be %2).Hopefully I explained it well. I tried searching for "variable in execution path" and "variable on execution" with other mixes, but none of those searches return what I am looking for.
How can I create a DLL declare statement with an environmental variable in it so as to make sure that I'm loading the system DLL from the right place, the system32 folder? For instance...
Declare Function GetExtendedTcpTable Lib "iphlpapi.dll" Alias "GetExtendedTcpTable" (ByVal tcpTable As IntPtr, ByRef tcpTableLength As Integer, ByVal sort As Boolean, ByVal ipVersion As Integer, ByVal tcpTableType As TcpTableType, ByVal reserved As Integer) As UInteger
The reason I'm asking is that there has been talk about people injecting invalid/malicious DLLs into folders along with applications and whatnot and I see this as an issue if you don't specify the SYSTEM directory. Yeah, I could specify it to load from c:windowssystem32 but what happens if a person doesn't have their Windows installed in c:windows? Hence the reason to use an environmental variable to find system32.
When im naming a variable for a directory should i end the variable name with path, folder or directory.

I would like to create a filepath and assign it to a string (so that it can have yet more added to it later on in my program) the code takes (well i want it to but it doesn't) the name of a drive selected previously and then adds this to a string to create a string variable that refers to a file. and then (as usual) i want to use thes files and display them in a combobox but i want to only select files that have a pre selected 2characters at the front. I have got this code so far:

View 12 RepliesThe 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 RepliesI 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

I 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")
Dim img As MODI.Image
