View 7 RepliesOpening Files With Alternate Programs?
Dec 4, 2009I am writing a program that stores filenames, along with a lot of information about the files in a database. I need to be able to open these files in three different programs from my application. One of these programs, AutoCAD is the default program for the files, but the other two are more difficult. These two need to open the file in a program that is not the default for the file type. Eventually, I'd also like to allow users to point the application to the instance of AutoCAD, MasterWorks, or FeatureCAM that they want to open. I have found articles that explain how to open a file in a default application and articles that tell me how to open any application with a file name, but only 1 suggestion of how to control the program used to open the file. For some reason I cannot get AutoCAD to recognize the file I feed in if I use this method though, so I think it's wrong. This is the method I found that doesn't work:
Start("D:Program Files (x86)AutoCAD 2007acad.exe", file)file is a variable that contains my file name. Since this works fine when I take the program path out, I know the filename is correct, but AutoCAD says it is not.
Opening/closing External Programs?
Jun 15, 2009I want to make a program where I can open a program, and my vb program starts with it. My VB program will then use a timer to count to an hour, and then close out of both programs. So i started experementing with things and this is what i came up with:Dim myprocess As Process = System.Diagnostics.Process.Start("C:\Program Files\Internet Explorer\iexplore.exe")
That opens my program fine, but I dont know how to close it from there. Also I want my vb program to start automaticaly, not hit a button and my other program shows up.
How To Create A Simple Program That Monitors What Programs Are Opening
Nov 10, 2010I am wanting to create a simple program that monitors what programs are opening and if necessary close one or two. I would also like to know if it is possible to get the window title (using a simple function/sub) and check with a stored list of programs,
whether that particular program is allowed to be open and if so before the program can be opened a password dialog will appear asking the user to enter the defined password in order to continue opening the program. Is this possible? Also should the password entered not match up, the program/process will not be allowed to open and will be closed/cancelled.
some code or point to the part of the microsoft site that has information on getting window titles and how to close current programs open etc
Build A Class Or A Part Of A Program That Can Be Add Into Other Programs To Be Used In That Programs?
May 27, 2011I am sure this can be done, as Visual Studio is basically built this way. What I want to do is simply make a class that my other workmates can use. But rather than have it in a code form, I want to build it (partially), and then my workmate can add it into their programs (sort of, like the add reference for the .NET stuff).

View 1 RepliesOpening Form By Type Or Name
Jul 17, 2003How to create an instance of a form if it is not know in advance which formtype has to be opened. If you want to skip the chitchat: the .NET code example is at the end of this post. First the Symantec: when we create a new form, this form has a name. If we refer to that name, we actually refer to the name of the type of object that is just created. When to use of course when reading the subject you might think: why not just pass the form to a parameter that takes a form (or control/object)?
The answer is: you don't when it is not sure, when or if a new instance of the object has to be created or, as mentioned, when the procedure is called it is not known which class has to be created. You could of course hold a bunch of created objects, but that would be a shameless misuse of memory. Imagine the following scenario (seen something like this in a post, but can't find it anymore):
You have a class that is able to trap an event, say the doubleclick of a textbox, and has to open a form when it occurs. If it's always the same form, that's easy, but what if you want it to be determined during runtime? This is a quite common story: doubleclick on article opens the detail form of that article, doubleclick on supllier opens that particular form. If you use a form variable, how do you say to the class which form should be opened? This will not work
Code:
Dim FormToOpen as Form 'you don't want to open it right away, you want to know when the time comes what form to openFormToOpen = Form1You could say FormToOpen = new Form1, but then 1. an instance would be immediately created, even if it never will be used: memory leak. 2. you can never close the form, you'll always have to use the same instance created when setting the form. Consequently, you can never open more than 1 instance using this way.
The solution: use the type. If you know the type, the Activator class will enable you to open (and return) an instance of that form at any time and as much times as you like. (The Activotor class exposes the function CreateInstance which returns an instance of the specified object)The following code creates an instance of the type form1 and shows it.
Code:
CType(Activator.CreateInstance(GetType(Form1)), Form).Show()Or for better readability, the same code split up:
Code:
Dim FormToOpen As Type
FormToOpen = GetType(Form1)
Dim frm As Form = CType(Activator.CreateInstance(FormToOpen), Form)
frm.Show()
Opening New Screen In Same Form?

Combo Box Activates On Form Opening?
May 15, 2009I have created a main form in my program to which I have added a combo box containing 12 months of the year. What I want is when the selected month is changed it should call a subroutine which does a calculation. The procedure works but the combo box acts as if the selected item has been changed as the form is opening which is not what I want as at that time there is no data loaded for the procedure to do it's calculation. So what I want to know is, is there some way to prevent the combo box from behaving this way at start up?
