We have a current keygen for a set of our apps that's using des-ede2 in C++.
I need to make my vb.net app validate keys generated by that keygen.
I've been trying to create a working keygen for three months and I havn't figured it out. I first inserted two buttons and named one "Generate" and the other "Exit" and then I put in a textbox. After that I put in the code and debugged it every time I pressed the Generate button a 0 just popped up in the textbox. my code is below.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

My goal is to take some form inputs and prompt the user to download a summary of everything once a certain button is clicked. I have no need for the file once it is downloaded and so I'd like to have a solution where the data is streamed directly to the user. My current solution doesn't even prompt the user for a download. Can anyone point out what I'm doing wrong?[code]....

in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?

View 10 RepliesI have a way of moving a picturebox. I type either 1, 2, 3, or 4 in a textbox. Each number is assigned a direction. Then I click the mouse and the picturebox moves in that direction.

View 3 RepliesI am making an Auto Typer and it was going all good until I came apon a mysterious problem. When sending the space key or enter key with "Send Keys. SendWait" they come up with their numerical equivalent, 32 and 13.For example, a user types "test" into the textbox, and clicks "{Text} {Space} {Text}" in the options menu. The user clicks start and the output is "Text32Text32Text".Is there any way to just send the keys and make them appear as if you typed them on a keyboard?
View 5 RepliesWell I am trying to make a 2 player game but both players can't move at once unless they tap the keys (can't hold the key down or the other person can't move). How would I fix this as well as being able to go diagonally.Would this work?:Declare a bool value for each keypress below the public class thingy. Then use keyup to turn the bool off and keydown makes it go on. Then for the first player and second player I check if they are on and if they are than go to that direction...I think I would need a timer for that part but I dunno...

I finished my application and i have a registration system which checks with my server if the key is correct the program is validated and the trial part is removed. So my problem is that i do not want to seat all day by the computer and make serial keys. I want to make a program that will generate the keys for me. I looked into RockXp but that's a third party software.

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!)

How Do I Make Button.click Event Perform both the enter and period(del) keys on the numeric keypad? [Code] Case Keys.Enter and Case Keys.Separator do not work. Nor does anything like Keys.OEMPeriod for the period(del) key. I've also tried calling the enter key in a KeyPress event etc. But to no avail. Any ideas? I'm trying to mimic Windows calc.exe for a school project and thought I'd try throwing in a few extras such as numeric keypad functionality.
