All your vars are belong to us

vb does not have private variables.

The stub vb uses to transfer you to copymemory is already small Chuck of asm you can see it in second half of this blog post

If it’s a known static list to drive an intellisense feature you can ditch the type libs completely and just create a utility to dump them to an easier to use format. I just use text file formats. I...

You really have to start with the guid for the context of what’s relevant.

Different libraries can define the same function names and enum names

Correct it’s a 32bit dll only

glad you got it. this is one way you can watch it:



#include <stdio.h>
#include <windows.h>
#include <conio.h>
#include <cstddef>

int main()

from a quick google, ULONG is 32bit in both 32/64 process
pointers like Variant* will be 4 bytes/8 bytes in 32/64 process

if you are expecting oInst, you want the first? 4 bytes from the...

this is incorrect




' union {
' ULONG oInst;
' VARIANT *lpvarValue;
' } DUMMYUNIONNAME;

yup, you will just have to interpret the data manually later

so I guess you can get the udt values by name with tli if in ActiveXdll

Public Function...

if it was declared as public in an activex dll then it would be published in the type library.
you could use tlbinf to get the udt name, field names and types.



Dim mi As MemberInfo, ri As...

You can add line numbers to each line and use erl()



Private Sub Form_Load()
On Error GoTo hell
Dim a As Long
7734 a = "nope"
hell: MsgBox Erl() & " n1"
End Sub

You could shell 5 curl instances and watch the process id. Or 5 instances of your own program to do it.

The normal answer is to use 5 threads but it’s a fuss to do with vb

You could look into setunhandledexceptionfilter api. Especially if the crash is happening outside the vb code

It’s hard to get a clean bill of health with almost 70av vendors as long as it’s not the major ones I ignore it. It’s bad signatures hello world can come back with detections especially with vb6.

I debugged it a little bit and it looked like it used the win api directly

Edit: “windows internet api” for the pedantic.

I just tested one of my apps that uses this. It was returning nothing, but on further investigation the server was returning a 301 moved
message and it just was not following the location header....

if the loop is really long I actually prefer to use a goto label sometimes.
usually when I dont want to nest if statements another layer deep and not when an exit for will suffice.

Pass max and min values from .net to vb
And see how the vb data types handle them it will literally tell you if there is still a problem. If you don’t need to do math on them just pass them as a...

The ipc was do an easy form of marshal and synchronization across threads.
You receive the data and events fine but the ipc test would resolve any threading issues.

If they are in different threads try using ipc instead of a direct callback from .net to vb6
I always use wm_copy data since it’s synchronous.

Are you doing any copymemory or other api calls?

Sounds like a memory corruption problem is causing the program to blow up at a latter time which would explain why no error handlers are catching...

Yup, any time you invest in learning to integrate c with your vb will be well spent. It’s like putting money in the bank. There is so much c code out there and it can interact very seamlessly with...

I am pretty sure I have an example of a cdecl callback here:

I only use property let /get if I need to protect an actually value or take multiple actions on it being set.

unsigned vars and 64 bit values can be solved in a pretty seamlessly C compliant way with a couple extra classes

Variable Size is important. Longs are 4 byte reads, integers are 2 byte reads.
If you gobble up to many bytes with one read you will lose your alignment and start grabbing data from other fields.
