View 3 RepliesI registered a function that I made in Enter Key. But it is possible that if I used to register Enter Key for my function the original registered key of Enter Key will not be replace. So, the Enter Key will not be replace, it will just add another function for hotkey.
Here's my code:
Private Sub DexLogger_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Hotkeys
RegisterHotKey(Me.Handle, TZIH_keyID1, 0, VK_RETURN)

I'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.
View 2 RepliesI have a Function Named Logout. Code is below;
Private Sub Logout()
Try
SendRequest("http:url....)[code]....
Everytime I login, It seems to run the logout function also. It DOES NOT do the SendRequest, but it does the me.client.dispose() which logs you out of chat. Is there a way where i can make this function only work when a button is pressed or the form is closing. In the form closing and btnLogout code I have Logout(), but I only want it to run that function when you close the form or you press the logout button, not when you log in. Is there anyway?
I am writing a program that involves the split Function. The user will enter A, B, C. I wrote a splic fuction code (below). I am not quite sure if it is right, I would also like to know how to write the code for that split function when the user preses the save button after entering there input.
Dim strInput As String 'input string
Dim strOutput() As Sting 'output string array
strInput = "A, B, C," 'user input
strOutput = Split(strInput, ",") 'splits the input string
I think its called e.keys?

This is a easy one (i think) I am using MS access 2003 and. I am having problems continuing SQL statments to another line. I have been trying &_ and that doesnt seem to work with my SQL statements. How do I do this. I have some long SQL statments and it would be easier to break to another line, but I can't seem to do this. The statment below gives an error.
sqlz = "SELECT [Crosstab AUS].* INTO [AUS REQ] &_
FROM [Crosstab AUS]"
I have a 'For Each...' loop in the VB.NET code for one of the pages on my website. There is also a Try/Catch block within this code that currently contains an 'Exit Sub' in the event of an error being trapped. However, what I would actually like to do is to merely exit the current loop value and recommence the loop at the next value in the sequence.
How can I do this?

View 3 RepliesI am making a Tetris program and I have a 2d array 10 by 20 for the grid.I want the Tetris blocks I have created to move down one block every second unless the user presses "a" or "d" (to move left or right) then the block should move left or right whilst moving down.The problem is that I have created a loop for it to delay a bit but then it waits for the user to press a key until it continues the program. So the block will stop moving down and just stay where it is until they press something.I have been told that you can do this in C with something like if keyboardhit or kybd() or something then it will read the key but otherwise it will just skip that bit and loop round. So how can I do this in VB?

When you are putting in a long string of code it doesn't all fit, so I want to know if there is a way to continue that string on the next line. I believe it's something like & _ if I'm correct in thinking. But I'm not perfectly sure, I guess the question I'm asking is if you can continue a string with & _ or if it is something else.

View 2 RepliesI'm writing in Visual Basic, using Visual Studio Standard 2008, targetting framework 3.5.When debugging, I pause code and edit it in my Startup Project, then continue running.Where the code moves into one of my non-startup projects, I am sure I used to be able to edit that code and continue running.Now, whenever I try and do that, I get a dialog stating that "Changes are not allowed when the debugger has been attached to an already running process", even though I can still edit code in the already-running startup project.All of my code is in VB, there's no weird language crossover thing going on. Why can't I edit-and-continue my non-startup projects?

64 bit is a wonderful thing, except that MS currently has no plans to make a 64-bit IDE. However, you CAN compile your program to be 64 bit using AnyCPU or x64 compile options. However, by using either of those options, you cannot edit-and-continue.To enable edit-and-continue on an x64 machine, you must set your compile option to x86 in the Platform property of 'Project Settings > Compile'. If you do not have that option available, be sure that you select 'Tools > Options > Projects and Solutions > General > Show Advanced Build Configurations'.

View 1 RepliesI am using the MsgBox Function as a help on my program to notify users of unusable entries in my program. After the MsgBox pops up, and the user clicks on either 'OK' or 'Cancel', the program need to clear the box that the bad data was entered in, and continue with the program. What I am trying to do I guess is keep the program from returning unusable values by informing the user of entries that will return such values. But, where I am running into a problem is in when I click on OK or Cancel, the program continues as if nothing was called as a result of the MsgBox info being thrown.
Here is the code I have so far, mind you that I have used several of the other MsgBox codes to no avail.
I think what I need to do is have a line of code that calls my "textbox.clear" if certain criteria are met. but when I tried this, the program did not return to my GUI, it simply ran with a value of "0" in the "textbox.text" that the clear was called on.
The idea with System.IntPtr is to represent an integer whose width in bits correspond to the size of a pointer in the hardware and operating system that the CLR is running in, it's platform specific in other words. It supports 32-bit and 64-bit architectures only.This is a legacy from old-style C API's where pointers and ints were frequently treated as interchangeable. The Win32 API has many such parameters, where the width varies with the underlying architecture thus the mess with porting of code from 32-bit to 64-bit (we already did this once when going from 16-bit to 32-bit, funny how we never learn...).In practice, as is mentioned in other responses, it can be used to hold unmanaged resource handles and pointers etc that stem from the underlying Win32 functions. It can also be used to hold integers of the natural size for current platform. You can also use IntPtr.Size to dtermine the size of a pointer on the current platform.SO when you explain this to a child ;) this would be used to let program's flow at the same speed at diffrent kinds of operating systems?
View 1 RepliesI've written a testing program where my students write a test and the results are compiled in a text file. The text file is then emailed to me using SMTPServer.send(MyMailMessage). The program works, except that it takes a number of seconds for the email to be sent. The user clicks the next button, which should bring him/her back to my login screen for the next student, but instead it hangs while sending the email. How do I get it to do the emailing in the background, allowing the person to continue using the program?
