I am trying to get the position and text of all DeskTop icons, by sending a SendMessage to the desktop's listview, using LVI_GETITEMTEXT. Works oke on 32 bits, but on 64-bits I always get an empty string back. I also tried to do this using LVI_GET_ITEM< but the same result. No errors, but also no text string. (I do get the x,y position of the icon). What is wrong here?

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.
bear in mind i am pretty new to thisnow "Ultima Online" is the title of the window/game im trying to send a simple mouseclick to..
View 2 RepliesFirst of all, is it even remotely possible to have PostMessage or SendMessage "press keys" inside of a Fullscreen game? I.e. use the Chat? (Requires the user to activate the chat box, type in the message, then send it, which is all done with the keyboard)
I've tried many different ways using WM_KEYDOWN and WM_CHAR, and nothing worked.
[Code]...
I am trying to get it to activate the user's chat by pressing enter, type in the text, then press enter again. Except, I would like for the game to be minimized and allow this to work. Or, if while the game was running in fullscreen, that I was able to use SendMessage or PostMessage to type text into a Command Prompt Window.
I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

What is the best way to store 4 bits from a byte in VB.Net? Where best means:Most straightforward method of storage from a Byte type.The easiest to work with while performing bitwise operations.Straightforward conversion of the bits to other types.Storing them in a BitArray via it's constructor reverses the order of the bits. This means that attempting to get the value of the first bit will require looking for that value in the last entry in the BitArray.
View 3 RepliesI am moving Visual Basic 2010 Express from a 32 bits Windosw 7 machine to a 64 bits Windows 7 machine. My project contains a PowerPacks line. I have installed the PowerPacks (VisualBasicPowerPacks3Setup.exe) on the 64 bits system, and see them in the toolbox. When I try to open the project on the 64 bits machine. however, I get error messages:The designer cannor process the code at line 56:
Me. ShapeContainer1 = New Microsoft.VisualBasic.PowerPacks.ShapeContainer
The referenced component 'Microsoft.VisualBasic.PowerPacks.Vs' could not be found
I then thought I would just remove the (purely cosmetic) line on the 32 bits machine, but cannot discover how to do this (I would have though: rihgt click, and then delete, but this doesn't exist)

I 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?
