How To Get Multiple KeyPresses At Once
Jun 20, 2008
I am currently creating a Space Invaders game. Basically what I want to do is being able to move and shoot at the same time. The problem is that whenever one button is pressed to execute an action it cancels out any other button being pressed. I don't want that to happen. Currently I am just using Key down. How I can have multiple key presses at once?
Private Sub frmain_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Dim Loc As Point
Select Case e.KeyCode
Case Keys.Left
[Code] .....
That's my code. This is basically the last thing i need done in my project.

I'm making a mario-like clone and I just finished the jumping code. The only problem is that moving while jumping is extremely hard because if you hold down the up key and right key at the same time, neither one activates.

I want a way to be able to control all the keypresses on a given form. I tried overriding a WndProc of a form to achieve this but I noticed that my text box keypresses are not going to that wndproc. Whats the way to achieve this?

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?

How can you simulate keypresses and releases? I know you can essentially hit a key with Sendkeys.SendWait, but how can your code press and hold q, for example? I essentially wish to be able to call something like press("q") and release("q"). The effect would be the same as physically holding them down.

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?

I've started building a small game where you move around a PictureBox control with keystrokes using the arrow keys. Everything was working fine....until I added a button.
Now the button steals the focus so that every time I hit an arrow key hoping to move my image, it just selects the button.
Is there any way to make the button selectable only by mouse click?

I've been looking around for a way to accomplish this to no luck, but is it possible to have a series of keypresses (Like Ctrl + Shift + O) or something like that act as an event? I'm trying to find a way to make something like this show a form using the old Me.Show() code.

I have the following code to handle keypresses on the form:
Private Sub Form1_KeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Debug.WriteLine(e.KeyCode)
[Code].....
The first time I press any of the arrow keys the code is not executed and a NumericUpDown(NUD) on the form gets the focus. The rest of the times the arrow keys are pressed everything is fine, until I click on a button. Then the problem repeats, focus NUD, then fine.

I am attempting to keep user inputs into our application as clean as possible. One way I am attempting to do this is not allowing incorrect data type in fields (not allowing alpha characters when expecting numeric values)I found and implemented the following code:
Private Sub txtSocial_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtSocial.KeyPress
Dim UserKeyPress As Char = e.KeyChar
Dim isKey As Boolean = e.KeyChar.IsDigit(UserKeyPress)
[code]....

The user has to enter the text in the textbox , to write a text user need to press the keys and release the keys. Write a code to count the number of keypresses and keyreleases and display the value in the labels.

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one

I have been struggling to find a solution for this problem. What I need to do is build a server application that accepts tcp client requests from different clients running on same port say:1003. I experimented by using asynchronous mode call backs etc. but it disconnects once connection is established and does not respond for further requests from the same client.

Iam wanting touse sendinput in a dos or background type app (can be a regular app thats hidden) that emulates mouse clicks and sends mouse moves to another multimouse application. an project that im working on for my school i work at and i need to send the input to it. The overview of the project is i need to have this code be in a service that runs in the background that when a person does a gesture with my kinect code then it clicks the left mouse or sythesis it with sendinput (need mouse up and down sent for this to work). The end programs that receive input are: a program written in the multipoint sdk and mouse mischief. I though about using the default usb mouse driver as an emulated mouse driver to handle the part about creating a usb mouse device that works
since most newer computers are using usb.

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.

I am trying to list all printers (PrintersConnections) under all users (HKEY_USERS)
problem is I dont know the user name keys in advance and need to exclude .DEFAULT and *_CLASSES so first I need to list all key names (%usernamekey%) directly under HKEY_USERS then for all keys that lists lsit all keys under HKEY_USERS\%usernamekey%PrintersConnections
Here is the code I have so far but I get errors about object variable not set, I suspect because of the way I doing the for each and listing the key names and then doing it again
Code:
Private Sub DetectPrntrs()
Try
Dim RemReg As Microsoft.Win32.RegistryKey

I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.

List1.Clear()
