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.

View 1 RepliesI'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 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 am in process to develop an application for Windows Mobile 6.5 using Visual Basic 2005 and .NET Compact Framework. My problem is that I want to know if an instance of my application is already running and, in that case, I want to jump directly to that instance, without starting another one. I tried several solutions found on the internet but I think there are solution for desktop applications not for mobile applications because I have a lot of errors.
View 1 RepliesI am learning C# after tried Java. Ive tried to program a program that can detect keystrokes, however when i add onKeyDown on my form it work but only one key at a time. So ive tried to add my e.keycode detect to a timer and got error. private void key_Tick(object sender, System.EventArgs e, KeyEventArgs e)
That wont work and the timer wont run becuase i have 2 Args. Im really lost and do not really understand
New to these forums but have been a lurker for a while. I searched through some "multiple monitors" threads but didn't find anything that fit my current issue, so I figured I'd pose it in a new thread. We have users with 4 monitor setups that are very particular about their screen settings. When we have to replace a PC for whatever reason, it is always a hassle getting their screen configurations the way they were prior to the switch. Is it possible to create a small VB app that will scan their current configuration, save a "settings" file, and re-apply the settings on the new PC? What I mean by configuration is screen resolution, setting the primary monitor, etc. Theoretically this sounds like it can be done, but I wanted some opinions on it.
View 1 RepliesI found the code linked below on on of Microsoft's websites for listening for keypresses, however I can't seem to ge thte code to respond?
View 5 RepliesI 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?
im trying to click a checkbox im using Sendkeys.send("{tab 13}")
sendkeys.send("{+}") which i have been told will click the checkbox but unfortunately its not happening.
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.
View 1 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?
I have a function designed to detect if the program is being run on Win7. However, when it is run on a Win7 machine, it says it is NOT a Win7 machine. [Code]
View 3 RepliesI have a set of labels with autosize=false and autoellipsis=true.What I would like to do, on the MouseHover event for each of these labels, is to show a tooltip containing that label's text, but only if the ellipsis was necessary in that particular case (i.e. the text of the label was actually too big to fit).
View 2 RepliesI did a research but I can't find what I wanted. How I can detect the mouse that if I have move it or not?
I hope this is the last things I needs for the day.
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.
View 3 RepliesI 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 have an app written on an xp pc which I want users to run on Vista
The app needs to delete a file on a portable drive in a particular folder
This folder was created on the xp machine and copied to the portable drive
The app will not delete a file in this folder on Vista but it will on xp
When I check folder security on vista (which does not exist on xp) I find that the folder does not have full control assigned
my app will write a file to that folder & delete it but will not delete a file put there from the xp pc
If I change the security in vista to full control it works
what I want to do is see if the folder has full control when the user selects it and advise them they need to alter security as I can not do it in the program
basically I want to advise them the moment they select the folder, not when it fails to delete the file after entering misc details in the app which are reuired before the file is deleted.
How to detect and get the valid html tags?
View 2 RepliesI 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)

View 1 Repliesim trying to make vb.net translate input from an external device into keypresses. when bit = 1 i want the key down, when bit = 0 i want it up unfortunately with sendkeys it just sends the same keystroke over and over again. ive googled for days without finding a good answer.
View 7 RepliesI spent some time with data modems till I realized it's a voice modem that I'm going to need in my application. I see that there are some other commands for a voice modem, although nothing very elaborate. I would imagine you make the call as you would in a data modem ATDT etc and it looks like there is really just one command to send audio...
AT+VTX
AT#VTX
Not sure what this is all about except maybe just different standards? Still not sure about how to detect when the call is answered though. I won't be talking to another modem. Maybe the serial port itself has a pin change or something? You would think there would be a bit "somewhere" that the modem would generate when it quits ringing. I may have build my own outboard box to do this. (easy enough -- probably more reliable too -- modems sure need rebooting a lot it seems).
Here is the goal though --Voice modem calls out, call is answered, and I inject my audio from the PC sound card for a minute or so and then tell the modem to hangup.
I have a button on vb form and its click event will call Windows to run "system32calc.exe" which is work great. My problem is I do NOT want to have multiple calculators running even if i click the button more than once. Is there any way to detect the calc.exe runing and then disable my button event to call calc.exe?

Working with a couple of listboxes to display userid and emailaddress. I am writing an application for viewing SSRS reports instead of using the Report Manager. I am able to select the report and also send an email to users with a web link to SSRS report so that ReportViewer comes up for them to view, export or print the report. Currently I am only able to send to one recipient and I'd like to be able to send to multiple recipients. However I am having difficulty with the multi-select from a listbox. I have set the SelectionMethod to MultiExtended and so I can select multiple items from the listbox. Here is my code -

and I also add a messagebox.show to display my values, in EmailAddressTo variable, it displays "System.Data.DataRowView" so it was not able to capture the email address at all. Then if I debug further I eventually get the error msg - "The specified string is not in the form required for an e-mail address." because of the empty variable. Using SelectedValue, I was able to get at least the first email address but not the second one.
I have a rather complicated application (for me anyway). I have a word template setup with text controls. A web app with ASP controls and vb backend code binds data to the text controls using an xml file.

I am trying to send email messages to multiple email addresses from a listbox. Here is my code -
For i = 0 To lstbxEmailAddress.SelectedItems.Count - 1
If EmailAddressTo = "" Then
EmailAddressTo = CType(lstbxEmailAddress.SelectedItems(i), DataRowView).Item("EmailAddress")
[Code]...
I am able to get the email addresses stored in the variable EmailAddressTo separated by a comma in between addresses. However, it only sends to the first email address. I selected two addresses but it only sent to the first address. How can I add multiple addresses using the To.Add method?
I want to be able to send an array of mixed documents to the printer. One document may be a word file, another a tiff file and another a jpeg.At the moment the only way I can do it is to open a seperate print preview for each document which is not good from the users point of view.
