C++ -> C# VirtualAllocEx!

[suguimoto]

Hello! I got a problem with the lines below. I don´t know how to use VirtualAllocEx in C# , because I must allocate a certain space for a struct and an item (both are pointers). I´d like to know if anyone got any idea how I can do the same thing in c#. This code is from: http://www.codeproject.com/threads/int64_memsteal.asp?df=100&forumid=29535&exp=0&select=727974&mpp=50#xx727974xx[^] "Stealing Program's Memory"

LVITEM lvi, *_lvi;
char item[512], subitem[512];
char *_item;
HANDLE process;

_lvi=(LVITEM*)VirtualAllocEx(process, NULL, sizeof(LVITEM), MEM_COMMIT, PAGE_READWRITE);
_item=(char*)VirtualAllocEx(process, NULL, 512, MEM_COMMIT, PAGE_READWRITE);

Thank you!!

If you are trying to allocate memory in an unmanaged process, you can probably use PInvoke[^] to make it work. If the memory you need to allocate will be in another managed process, then those unmanaged APIs will not work. What you would need to do in that situation is, probably, use .NET remoting to communicate between the two managed processes. Josh

Hi Josh, thanks for the reply! What I´m trying to do is read a TreeView(Folder Browser Dialog) from another program. By reading each item´s text I can select a especific Folder. I noticed that usual codes did not catch anything from outside my program. For instance: SubString Text = new SubString(255); tvItem.pszText = Text; SendMessage(TreeHandle, TVM_GETITEM, 0, ref tvItem); This code works perfectly if the treeview is in your application, but SendMessage returns only false if the treeview is in another application(process). Thank you
