View 3 Replieshad a quick question that I dont think is too difficult, the solution just isn't too apparent to me.I put an option in my program that will allow a user to redownload a setup file and repair a program installation and I wanted the program to automatically launch the msi file and pass a command line arguent to use the repair function in the installer.This code works perfectly to launch the installer, but the user has to manually click repair.

View 1 RepliesI have the following code which works pretty fine with Listview. But I would like to use it with computer keyboard up/down arrow keys. How to modify the following code?
CODE:
In my old VB6 programs I use control events like Keydown to activate code. The code is the same for all text controls. However, I am hoping that there is a efficient way of handing this in VB.net. Using VB2010.
Private Sub txtField1_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField1.KeyDown
ButtonState2()
End Sub
Private Sub txtField2_KeyDown(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles txtField2.KeyDown

I was making a program where it takes text from a textbox on one form, and places into a textbox on another form. If the first text I am taking says "test" Then the buttons code would be:
Form2.TextBox1.Text = Me.TextBox1.Text
This works, however, if there were two textboxes in the first form, and I wanted this:
Form2.TextBox1.Text = Me.TextBox1.Text
Form2.TextBox1.Text = Me.TextBox2.Text
- this would not work because one of them will override. I wanted to know how I could send a key into the form just once. I have tried this:
Form2.TextBox1.Text = Me.TextBox1.Text & ("{ENTER}")
Form2.TextBox1.Text = Me.TextBox2.Text
how to remove a backgroundimage in the code whenever I activate colordialog :

I have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done
How would I create a code that can be called apon to activate but not recive or send any information through the program.And just to clarify what I mean by that is it will read information out of a textbox and write into it. But it wont actualy recive anything or send anything back from where it was called apon.
The error it has is that when one of the text boxes is changed the code changes all of them triggering every single function to activate. Is there a simpler solution other then recoding it from the start? also each different Private Sub is identical basically.
Public Class Form1
Private Sub K_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles K.TextChanged

I know the code is very brute forced & sloppy but its the only way i really know how to do it.
When I typed Private Sub cmdAbc_(Click) and pressed Enter key the first 12 characters erase leaving cmdAcc_(Click) and the cursor on the next line. Then pressing the up arrow or space bar restores the erased characters. This problem makes coding a program impossible. Programs I created before the problem arose do run successfly, but the code for those programs displays with missing characters.

View 1 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
Can i activate the Ctrl+Esc ?
View 9 RepliesI am creating a web browser in VB 2010. I have a search box, and I want to make it so that when I press enter in the text box, it searches. [code] The problem with this is that when I press enter, there is this annoying "beep". I don't know where this comes from. The only thing I can think of doing is making the event activate the search button, but I don't know how to do that either. How can I fix this?

View 6 RepliesI'm now working on a domainchecking application for about 2 weeks and it is in the final developement phase.There is a my.settings that is, by default 1 to indicate that it is the first time starting the application. If it is the first time, the settingsform will show up to activate the application with a serialcode. This works fine. If I start up the app again, it doesn't show the settingsform again because my.settings.firsttime was set to 0.
After 1 cycle of the timer, which checks all the domains,the line: application.restart is being executed. Then **** happens...It shows up the welcome-message again and asks for activation.By check,I put a button on the settingsform which shows you the value of my.settings. firsttime. and ***... It is 1, like magic, it changed itself from 0 to 1. The same problem is with the indicator of the activation.Is the problem caused by application.restart? Is there alternative code for restarting an application?

View 3 Repliesi would like to know that is there any way to activate a button with the Ctl and a key combination
we can do it with Alt and the key combination but my client is asking for ctrl & the key combination i have searched a lot but failed to find anything.
secondly :
i have used the alt & key combination for my buttons but the prob. is unless and untill the user presses the alt key the key combination is not highlighted. i have seen progs. where the key that is used for e.g. i have given &Add then the 'A' key is highlighted always with the underline. but when i am doing it by giving the name as &Add unless and untill the user presses alt the underline under A doesnt appear. do i have do more than just giving "&Add".

View 2 RepliesOn my program I am trying to make a form that would activate the program.I have the activation codes but when the user enters the activation code in a text box, is it possible that it would erase that activation code or wont accept that activation code again after being used once. Then if the program accepts the activation code can it open the main form (form1) and if the user closes the program and the re-opens the program, is it possible that the activation form doesn't open again and instead, going to the main form. I have this password code:
Private Sub textbox4_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MaskedTextBox1.KeyDown
Static WrongCount As Integer = 0[code].....
Then can there be slashes every 4 characters in the text box?
