View 2 RepliesI'm using the following code and it's bringing up this error 'PInvokeStackImbalance was detected'.
Public Class Form1

This code worked fine in WinForms under .NET 3.5, but since I've started using WPF and .NET 4.0, it no longer works (although I'm not sure if this is a coincidence or not). The purpose of this is to detect if a mouse button (or multiple mouse buttons) is being pressed outside of the application.[code]...

View 3 Repliesim trying to make a program that only listens to a few keys that the user presses, and if one of them is pressed, it carries out a specified command.for example, right now,i found a keylogger that could carry out my command, but id rather use something else if possible. right now, i have a timer running this:
For i = 1 To 255
result = 0
result = GetAsyncKeyState(i)[code]....
Then, in the textbox1_textchanged, i search for like if textbox1.text.contains("M") or something.problem with this, is im pretty sure its a keylogger, and i dont want to have to have that. also, it does not work in vista.
Found a solution! (should have researched more throughly!)
Option Strict On
Imports System.Runtime.InteropServices[code].....
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Button1.PerformClick()

Dim starthotkey As Boolean starthotkey = GetAsyncKeyState(Keys.V) My question is... how do i change my hotkey from "V" to ctrl+V?
View 8 Repliesi made a .exe launcher, i was able to launch a program named minecraft using the process.start. But this certain program generates error usually, so what i tried to do was get the window title of the minecraft and categorize if its an error or the actual game.
This is what i did:
Code:
So this transfers the window title of the launched program to a textbox then the "if statement" compares it and if its the error, it kills the error and relaunch the program. This is already a working program but i want to make the launching faster, the problem is if i hasten the interval of timer 2, it sometimes kill the non, error program that successfully launched. If anyone can help me, Hide the error or remove it please do help me. Im not yet an expert on vb.net but i want to learn from the best.
I am trying to create a new library (.dll) for use in my SSIS project. I dont have any prior experience of creating these kind of projects. So please bear with me.
When I try to debug the program, it throws the following error
What would be the best way to debug the following code. I know that it maybe wrong, but I am trying to learn this.
CODE:
The program has errorhandle and write log function, however, it could not catch the error message in the program.
The following error message in Event Viewer. Error Module: oleaut32.dll ,version 5.1.2600.5512, error code: 0x000048f9
My Intent:I am developing an application for myself which will take a series of keycodes pressed by me(even if my program is not in focus) and execute commands associated with it.It is basically like developing hotkeys.What I Have Tried:I have searched well and tried to implement GetasyncKeyState() in my program and it works well....but the problem is, it tells if a certain key is pressed but not which key was pressed last, which is what I want........I need to know which key was pressed so that I can make a word out of it and check if it equals my predefined names to execute the command, something like this:
Dim word = lastkey
word = word + lastkey
if (word = "startnotepad")

In my MDI Application code I have a form that launches a second form then hides itself until the spawned form closes. It works great unless I choose to close the application while the spawned form is still up.
The following is some example code.
Dim ChildForm as New frmTaskWindow With { .MDIParent = Me, .AddingNew = True }
ChildForm.Show
Me.Hide()
[Code].....
Me.Show() ' error occurs here because my form is already closed by the system. Is there a way to get around this without just an error catcher?
I have a really annoying problem. I use GetAsyncKeyState() to determine if a key was pressed or not.Unfortunately, that event fires as long as I hold down a key. Is there any way to check if a Key was released?
View 1 RepliesI have a program that tries to grab keyboard imput using GetAsyncKeyState.On XP 32 bit and win7 32 bit it runs fine but on Windows 7 64bit it doesnt regester any keys being pressed. Any Ideas?
If GetAsyncKeyState(Keys.F12) < 0 Then
If isF12 = False Then
If toggle Then
[code]....
I have looked at many of the tutorials, however, using 64-bit windows vista home premium using those examples, it doesnt seem to work, however, I don't have other computer to test on, is there a good way to do what GetAsyncKeyState does on my system?

I am trying to input the function key that a user has selected from a ComboBox (containing the function keys F1~F12 as options) into the GetAsyncKeyState(). However, since the ComboBox_StartHotkey.Text is a string, it cannot be converted into Long data type needed for the GetAsyncKeyState() function. I have tried Conversion and Parse Methods but what I try doesn't seem to work. Anyone know how to effectively convert a String (such as F6) into a Long data type for using in the GetAsyncKeyState() function in this case?
I used the tried to use the ItemData property to hold the Key Code representing the Function Key.
When I press F7, nothing happens. I got the Virtual Key Codes from here.

How would I use Select Case with GetAsyncKeyState? Ive tried Select Case GetAsyncKeyState End Select and I get Argument not specified for parameter 'vKey' of 'Declare Ansi Function GetAsyncKeyState Lib "user32"(vKey As Long) As Integer'.
View 2 RepliesI'm trying to make a rs232 serial data logging program, that accepts a 12 bit hex RFID tagID from an RFID module. My end objective is to save this RFID tagID into a database and assigned to a person for a personnel management system.I had to use button3 to add the value of the variable 'msg' into textbox1 because I was getting the following error "Cross-thread operation not valid: Control 'TextBox1' accessed from a thread other than the thread it was created on". It is a temporary workaround.When I do press button3, I get the incomplete hex number, instead of "4C00A2C82A0C", I get "A2C82A0C", and sometimes I get random digits like 1,A,C etc etc.

View 5 RepliesI have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

View 6 RepliesI got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

View 1 RepliesI am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

When I click on the icon of my program it shows the error message
