I'm trying to rewrite a C++ library. But I have an issue. I'm not extremely pointer-savvy. In the C++ class there is a std::vector that holds unsigned int pointers (vector<unsigned int*>), and the int pointer just points to an array of integer data.
Here is the C++ code I'm a bit unsure about:
unsigned int* relocation = m_relocations.front();
m_relocations.pop();
unsigned int* reloc = *(unsigned int **)relocation;

How can I declare pointer to pointer in ATL. Actually I have a handle which I want to pass by address to function. As shown below
STDMETHODIMP Function(HANDLE* hHC) //HANDLE declared as void * so actual type is void **
OR
STDMETHODIMP Function(LONG **hHC)
And want to access this function from the VB client.
So there is a program that is missing some files and written in C++, and it can no longer be compiled. Therefore I am trying to rewrite the program in Visual Basic (C++ is not my preferred language... lol) And I need some help understanding what this code is doing and how I can, in a way, "convert" it to VB language. I looked for a C++ to VB.NET converted but it costs $199 and I actually want to know what the code is doing... Here is part of the code for one of the C++ files (it is part of a program that decodes a file type into a readable format, BTW.):

I want to know what is going on here and how I can recreate this in Visual Basic.
Currently I have to parse each row in the file into a string array segments(). Then I look at the first few elements to see where I am at. E.G.
'Patient Loop
IF Segment(0) = 'NM1' and Segment(1) = 'QC' and current loop = '2000' Then
PatientFName = Segment(2)

I (almost) finished a project (using VB.NET Express 2010) and now I'd like to rewrite it in HTML5 or CSS or Javascript or AJAX, or embedded Flash. Which one would you recommend? Which one as those 5 would be easier to learn for someone with some vb.net experience?

I'm using ASP.NET 4 / VB.NET / IIS to build a web application.

View 1 RepliesAfter rewriting a VB.NET assembly with Mono.Cecil the 'Call Stack' debugging window in Visual Studio 2010 shows the language as C# and not VB.NET. Is it possible configure Mono.Cecil to rewrite an assembly so the debugger recognises the rewritten assembly as VB.NET?The following Mono.Cecil simply reads and saves an assembly without modification. However, the debugger reads the new assembly as C# instead of VB.NET.
Dim readerParameters = New ReaderParameters() With {.ReadSymbols = True}
Dim writerParameters = New WriterParameters() With {.WriteSymbols = True}
[code]....
It is desirable for the rewritten assembly to be VB.NET so the debugging windows 'Local' and 'Immediate Window' are the VB.NET versions rather than the C# versions.

View 5 RepliesI got that little function(I changed the name of variables)
Private Function everythingLinked(ByRef myClass As cls, ByVal found As Boolean) As Boolean
If Not found AndAlso myClass.checked = False Then
myClass.checked = True

I want to rewrite it so it would only be loop and no recursion and I'm currently lost?I'm passing a class to this function(with a starting value for found as false) to know if it is linked to the middle of the tree. The class got an array with a maximum of 4 link to other class and it can be circular(this is why I have a checked_link boolean).It does the recursion until there is no more link(return false) to check or until it find the middle link(return true).
edit?for an example, this
in pos 0 got link with 1
in pos 0 got link with 6
in pos 1 got link with 0
[code]....
middlepoint would be pos 15 the code above can prove that every position can be linked with the middlepoint so initial arg would be
everythingLinked(random pos, false)
and in this case it would be always true

I understand there are no pointers in VB.Net. I need to use something similar.The issue is that I have a structure that represent a deck of cards, with elements showing how many of each type of card there is. So I have my_deck.ace, my_deck.two, and so on.What I want to do is set a pointer called current_element that refers to any element in the structure. It may one time point to my_deck.three, and another time to my_deck.nine, and so on. It could point to any element.What I want to do is, for instance to set current_element to point to my_deck.ace, then decrementing current_element would reduce the count of aces by one.[code]that would work, but it's inelegant, I have about 30 different operations to perform, some of them using several lines of code. I'd like to avoid this if at all possible. I could tolerate doing it 2 or 3 times, but not 30.

View 7 RepliesI've got a 3rd party C application that's compiled to a non-.NET non-COM DLL. It has one simple function declared like so: Declare Function CapiTaxRoutine Lib "taxcommono.dll" (ByVal sInData As String, ByVal OutputData As String, ByVal intINPutLength As Long) As Integer
If I place the taxcommono.dll in my path (C:WindowsSystem32 is what I'm using because it's what the vendor recommends),I can wire up a call to the function and it works just fine.It returns a 1 or 0 for success/failure, but it also sets the value of the OutputData string parameter (using some C pointer magic I'm not familiar with) to a huge fixed width format return record that has the data I need.When I call it from a .NET .exe application, it works just fine.When I try to call it from an ASP.NET application via a referenced compiled .NET wrapper DLL, it runs but can't set that string.In order to get it to run, I can't have taxcommono.dll in my path, but rather have to place it in my Bin directory of the web project.Does anyone know of a reason it can set the pointer when called from an .exe application but not when called from a web app?The .NET wrapper DLL I'm using works when called from our ERP software, which is not web based. But when I add a reference to that same DLL in the web app, it won't give me that output value.am used to just getting a return value instead of a function setting the value of one of my input parameters.
