Do anyone has any idea of how can I drop files to another app? I have found that it can be done with SendMessage WM_DROPFILEs, but I don't know how to structure the wParam.
I also found this on MSDN [URL]..But I still don't have any idea of how to do it,I also found this code, but is for Delphi:procedure DoDropFiles(Wnd: HWND; Files: TStringList);

Damned. Is there a managed code somewhere in vb.net where mortals can simulate key presses?
Is there an e-book or book somewhere about it?

I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc. However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped.
How can I overcome this? Is there any way to delete embedded files from richtextbox?

I am working on a vb forms application in VS2008.What I am looking to do is have 3 file managers on the form.The top is the source where files can be copied to the 2 other file managers.What I have been looking for is an example of the file explorer so I can modify it.So far I have been unsuccessful in finding a good example so I am here to ask the experts.So the gist is the first file explorer will allow a user to connect to thier local hard drive.The other two file explorers would allow the user to connect to two different servers through entering the path they want to view those file trees.After that the user could click on the file they want to copy and then hit a button for example and the file would be copied from the local to the two other areas.Would it be easier to just use text boxes with a confirmation that the files are being copied?Or can a full file manager be built to drag and drop files?

I am using SendMessageTimeout to send messages (IPC) to talk between applications ... works fine in vb... but i am trying to build a vb.net implementation to talk between existing vb6 apps and .net ones...
So far i can successfully send data from vb.net to vb6 using:

Dim Data As New COPYDATASTRUCT
Data.dwData = New IntPtr
Data.cdData = UBound(b) + 1

I would like to get the x, y position from the Params when the WM_LBUTTONDOWN is sent in vb.net.I got this to make the param but how do I get the position from it.
IntPtr lParam = (IntPtr)((y << 16) | x);
My function:
Protected Overrides Sub WndProc(ByRef m As Message)
Select Case m.Msg
Case WM_LBUTTONDOWN
[code]....
Update: I just tried this and it works perfectly.
Dim pos As New System.Drawing.Point(CInt(m.LParam))
Private Const WM_KEYDOWN = &H100
Private Const WM_KEYUP = &H101
Private Const VK_BACKSPACE = &H8

I have this code:
Private Const MOUSEEVENTF_LEFTDOWN = &H2
Private Const MOUSEEVENTF_LEFTUP = &H4
Dim WindowHandle As Long = FindWindow(vbNullString, "Ultima Online")
SendMessage(WindowHandle, MOUSEEVENTF_LEFTDOWN, 0, 0)
SendMessage(WindowHandle, MOUSEEVENTF_LEFTUP, 0, 0)
I know it is getting the windowhandle fine, because I made a conditional statment that pops up a messagebox if windowhandle = 0 The problem is that it is not sending the mouse click to the window.

View 2 RepliesI use keybd_event and mouse_event to simulate keypresses. I want taht to still work when the user is switch (Xp supports several users as we know).
Well, it doesn't.
I've heard sendmessage is more reliable,.
I manage to simulate click easily.
SimulateClick2 = SendMessage(hwnd, BM_CLICK, 0, 0)
Now, how to do so to simulate keypresses?
Can anyone give me a SendMessage/PostMessage Example? I want to make SendMessage/PostMessage work like SendKeys, except instead of sending keys to the app in focus, it will send keys to a certain app. I've looked at a lot of examples that use notepad, but they all need to use "find" the "EDIT" thing. I dont want that. Is there any other way?
