Pass Data To Dialog - Manipulate And Pass Back?
Jan 15, 2010Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code:
Public Class Form1
Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.

Reference To The String In The Heap Is Passed Even When You Pass The String ByVal To A Method?
Mar 2, 2011So strings are reference types right? My understanding is a reference to the string in the heap is passed even when you pass the string ByVal to a method.

VS 2008 Win.7 Program Compatibility Dialog?
Jul 8, 2010I've made a program which runs smoothly on XP and also on Windows 7.But after installing it on a windows 7 machine, windows 7 immediatly shows another dialog box of the program compatibility assistent stating:(translating from Dutch, so forgive any mis-translations )
'This program may not have been installed correctly.If this program is not correctly installed, you can try to reinstall the program with compatible configuration of this version of windows.'You than have the option to reinstall the program with the advised compatible settings (?) or choose 'this program is correctly installed'.
If you choose 'reinstall with adviced compatible settings', windows 7 installs the program with 'windows XP, SP2' settings.My program uses only an access database and an internet connetion. Nothing fancy, exotic, registry items or something else.
For writing permission on the database (also win.7), I install the program in 'all users/app data', and not in 'Program Files'. I can't find anything usefull on google,

View 2 RepliesUsing Shell To Run Program On Server That Requires A Dialog Box
May 8, 2009I am using this statement
CODE:
The command procedure calls a Java program that opens a dialog box, the cmd and java exe shows up in task manager, so I know it is being called, but no dialog box. I know normally having anything show up on a server that requires user interaction is a bad idea, but in the case, the users remote into the server to do their work. (They have to because of the environment) So, there is no problem with them being able to respond to a dialog box. I just need it to show up.
(I cannot rewrite the Java program as the latest source is not the right version) Running, Framework 2.0, 3.5.
How To Pass String Value To BackgroundImage
Oct 10, 2010I am writing a simulator for a complex technical system. I have created a custom control which inherits from the Button control. My project requires around 100 of these buttons, which function identically except for one difference. The background image cycles between 4 different images, (depending upon whether the button is pressed and/or the state of a Fault parameter), and this group of 4 images is different for many of the buttons. So when I drag a new control onto the form, I'd like to be able to specify which group of 4 images to use for this button.
Currently I'm using this syntax:
if not IsFault and isOn then
MyBase.BackgroundImage = My.Resources.FaultOnButton01
...
But this means I have to change each image in the code for each individual button. To simplify matters I though of using the Tag attribute. That way the class code can select the images by a process like this:
if not IsFault and isOn then
Mybase.BackgroundImage=My.Resources. + mybase.Tag + "01"
Obviously this syntax won't work, so my question is: How can I pass a built-up string value to the MyBase.BackgroundImage?

View 8 RepliesPass A String From VB 2010 To A Fortran DLL?
Aug 3, 2011I can pass integers, singles, doubles, and arrays of all these back and forth with no problem. But I can't figure out how to pass a string in Visual Basic 2010 to a character variable in the Fortran DLL. I keep getting the PInvokeStackImbalance error. I could just convert the Visual Basic string to an integer array containing the ASCII code for each character, send that, and convert back inside the DLL, but that's pathetic. There must be a simple way to do this.
I first tried using Dim txt(50) as Char in VB2010, and character*50 txt in the DVF F90 DLL but that didn't work.
Then I tried Dim txt as String in Visual Basic 2010 and made the string 50 characters long (also tried 49) but this didn't work.
