I am creating a program that has many text boxes and labels on the form. I want to be able to edit fields close the program and open it up so that the form opens with the last editing I did in the fields.
View 1 RepliesI currently have a program that I made which opens other apps packaged with an installer. I have set the installer to install everything to the Program Files folder. However, not all computers have a C: hard drive. I have a way in which they can enter their drive letter in one form then in the next form it remembers the drive and will take them to the program. The problem is my program stores the drive letter in an xml file. On the startup of the program it looks in the xml file to find the drive letter, if there is no drive letter the form opens then lets the user set his drive letter. The xml file is stored in the folder "Math Wizard" in the Program Files folder. But if not all computers have C:Program Files I need a shortcut to the program files folder. I have been trying to use %ProgramFiles% (%Program Files% + "Math Wizardconfig.xml") but vb is saying that the % is an invalid character. Here's my code:

View 4 RepliesI want to be able to double click a custom file that contains text and it pulls up my program and adds the text in the richtextbox.
Basicly I created a file extention called .pwt but I can't get it to load the text stored in it on the richtextbox.
How can I combine specialized string collections so that I can accomplish this :
-Save all the tab's texts from a tabcontrol
-Save contents of the tabs : eg.Every tab contains a label and I save the text of each label
And the real problem:
-Loading them when the program opens
I have made some thoughts about saving them, but not about loading them
setting.TabNames.Clear()
setting.TabLabels.Clear()
For Each item As TabPage In TabControl1.TabPages
Dim name As String = item.Text
setting.TabNames.Add(name)

I have a form ( call it NewForm ) that can be opened from many other forms, but I don't want to have the user to run into the problem of having many windows/forms open.I want to close the calling form and open NewForm.NewForm will prompt the user for information, but if the user doesn't find what they are looking for I want to have a "Cancel" button on the form. With the "Cancel" button I want to go to the previous form.is there a way to tell which form called NewForm so I can just reopen/unhide that form/window.
View 5 RepliesWhen I initialize a new form to open, the subroutine in the new form starts before the new form is shown on the screen and so when the subroutine finishes and the MsgBox comes up, the form isn't showing.
Is there a way to make the form pop up first before the subroutine starts?

View 4 Repliesim trying to make a program that opens multiple urls in a webbroswer box. like a url opens and after it loads that url closes and moves to the next one.
example: i have around 4 to 5 url....
[URL]
so how do i make it so after it loads google.com it moves to the next url [URL] but i wanter to do that in the same webbrower box.
I have ran into a small problem with my code. I got bored lately so I wanted to try a project. A program that will start up with windows starts up and it opens a webpage like google.
My code is below.
Imports System.IO
Public Class Form1
[CODE]...
I use the code [code] System.Diagnostics.Process.Start [URL] when a button is clicked, but when I add that code in without clicking a button, it does not work. I have tried to put it everywhere, but it just does not work. I have also looked it up.
I created a webrowser in VB.net to track employee usage and it seems to be working fine but I wanted to find out what it would take to set this as a default browser on a PC.I also would need to know how to pull the URL from shortcuts so when the program opens I can have it open to the URL in the shortcut.
View 7 RepliesIm trying to use a Settings file that the program opens and reads the info from when it loads BUT when the user chooses a custom color (ex: ff5f67d6) How can i assign the form background color to that color code?
Dim BgColor As Color = ColorTranslator.FromHtml(Settings(0))
Me.BackColor = BgColor
Settings(0) = the color code
that is the code i tried to use that doesn't work
On my form i use binding source bound to fields.. if a user starts to change something then hits cancel (i set all the fields to "" to clear them) and then if they choose that record again it shows nothing in the bound fields..
is there a way to reset/cancel from editing without loosing original values?
when you login it is the meaning that another form opens. But as soon as the new form opens up everything closes. The code i used is this:
Public Class Form1
Public Goldhave As Integer
Public UserName2, Password As String

I am using VS 2008, Windows XP R3, and Visual Basic.When I open some forms in the form designer, (In Solution Explorer, right click on the form, then select View Designer) the form always opens as Edited. An Asterisk "*" appears after the form name in the open window tabs. If I open the form to just view the code (In Solution Explorer, right click on the form, then select View Code), the form opens normally. This happens for just some forms.
It always happens for the same forms, and never happens for the other forms. What I am missing in those forms where the designer always thinks the form has been edited?
When opening a button and opening a new form as soon as it opens it close for some reason but its not giving any errors as to why its doing this now I've checked the linked linking it to the next form that's fine.
Private Sub PrintPerscription_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Login.con.Open()
sql = "SELECT Patient.* FROM Patient where Patient.Wardno = " & Login.WardNo.ToString

noOfRows = da.Fill(dsPatient, "Patient")

View 5 RepliesI'm developing the program which opens files/programs that I have selected and checked with checkbox1, 2 and 3(i haven't coded the tihrd one yet, but it doesn't affect). The first program runs instantly and others run after X interval if it's wrote in textbox4 and checked by checkbox4. So Checkbox is like an activator for this interval. If checkbox4 isn't checked then every program should run instantly. The problem is that checkbox4 isn't doing a job. Program activates the interval if there are somekind of numbers in textbox4. It doen't matter that is the checkbox4 checked or not.

I need to create a program that requires password entry. I was thinking of having a form that the user uses to set the password that only opens once (unless a button on the main form is clicked to reset the password.) once the password has been set, the form closes and another opens to enter the password and for each and every time the program is run. Another thing is that if the password has been entered wrong 3 times, the program gives a message box and closes on the ok button.

View 2 RepliesI'm trying to set my software up so that when I check the checkbox for winRAR to be installed, it'll pop up a new window asking if I want to install the 32 bit version or the 64 bit version. I have no problem getting the window to show up but than if I try to exit out of the window and than uncheck the box (in case it was accidentally checked) it'll just open the window again. I am thinking I have to tell vb that when I uncheck the box it shouldn't do anything.
Here's my code.
(I know that the Nothing under the Me.chk_rar.Checked = False doesn't work but I left that blank once and it just opened a bunch of windows and crashed my system. I know it says "E:Music" right now but I just pointed it there so that there was something there normally it'll point to the other window. If I need to created a new Form for every little window that I have for instance the little window that I want to pop up, do I need to create a new form just for that little window to ask which architecture is needed and than giving the options for 32 bit or 64 bit.
