I've got a class which consists of a persons name and their height. I then want to sort there height which is in an array, which I can do. However when I want to display both the height in order with there name I can't. The heights are sorted in order but the names just appear in the order they were entered. How do I make the right name appear next to the height?
View 2 Repliesi have to write a program for my VB class that consists of a resistance checker program. I've searched like a madman to help me through this and I have found nothing >. The program consists of 2 combo boxes, the first one is the nominal resistance drop down list of the numbers :100, 150, 220, 330, 470, 680, 820 and 1000. The second list is of the tolerance numbers; +/- 0.4%, +/-0.6% and +/-0.8%. Now what i want to do is select a number from the first combo box and select the tolerance level of the second combo box and i input the resistor of said value into the text box. when i click the check resistor button it should display a message saying if the resistor is in or out of tolerance. For now I have the form all laid out and the values inputted into both combo boxes and i can go to run the program i am able to select said values. Now my problem is trying to get the right code so that i can check the resistors value.

Of course depending on the the computer & internet speeds & everything it will vary how good it works but i'm trying to do it over computers with really fast network/internet speeds & computers, other ways to do it given to me have been really slow, I couldn't even make my app display the picture at even as much as 10fps & that was without sending it over for another computer to display & displaying it in the same application.

View 1 RepliesMy application consists of about ten Forms so far. One of the forms gives the user the option of choosing the language that all the text on the forms will use. Each Form has a declaration like this
[Code]...
I have this declaration (Public myLanguage As New DataClass.LanguageStrings) where I had intended to keep my working copy of the chosen language strings, so that each Form's Constructor could set the xxx.Text properties using this type of assignment - ... = myLanguage.yyyStrings.xxxString. However, the IDE throws an error at the first occurrence of "myLanguageSet" in the module SetLanguages above, saying that I should use "New" to declare an instance which I can then use, despite the line above that point where I thought I was doing just that. It doesn't seem to matter where I put the declaration of myLanguageSet, I just can't avoid the "New" error being thrown.

View 1 RepliesOur Winform app consists of a Main.exe and a Launcher.exe. The purpose of the Launcher app is to check for updated versions of the Main.exe. If it finds no updates it launches Main.exe using System.Diagnostics.Process.Start
If it finds an update, it copies the new Main.exe into position and launches Main.exe the same way (in this case it will be a fresh copy of Main.exe).Here's the Process.Start code:
Dim p As New ProcessStartInfo
p.FileName = "Main.exe"
p.WindowStyle = ProcessWindowStyle.Normal
Process.Start(p)
This code executes whether or not there's been an update and always successfully fires up Main.exe.However our Main.exe, if it's being run for the first time (ie. after an update), will error on any line which references the My namespace, such as My.Settings or My.Computer.FileSystem For example this line will cause an error:Msgbox(My.Computer.FileSystem.SpecialDirectories.Desktop)
Here's the error: System.IO.DirectoryNotFoundException: Could not find special directory 'Desktop'. at
Microsoft.VisualBasic.FileIO.SpecialDirectories.GetDirectoryPath(String
Directory, String DirectoryNameResID)at
Microsoft.VisualBasic.FileIO.SpecialDirectories.get_Desktop()
at
Microsoft.VisualBasic.MyServices.SpecialDirectoriesProxy.get_Desktop()
But while this example refers to Desktop remember it can't find any of the SpecialDirectories. It's not restricted to Desktop. But only the first time it's run (ie. immediately after an update). Thereafter it will run fine.If the process failed more spectacularly, to do with file system issues, locks or threads, it would be more understandable. But why just this "minor" problem with the My namespace?
I am trying to make a program that consists of two list boxes.

View 3 RepliesI have an application that consists of about 4 screens. Screens can be changed by clicking on buttons or via menu item. I use about 16 to 17 tables in all for all 4 screens. I've publised the application and it works fine except that it takes about 1 1/2 to 2 minutes to launch the application using the setup file that I save onto my PC. If I get lucky, a little over a minute is already fast for me. What can I do to help speed up the launch time?

When I double click on the row which consist of Brian/Kendall, a form will appear and should show Brian in the First Name text box and Kendall should appear in the Last Name textbox.
I have to write an application that consists of mainly one main form, but several different things I wanna display. Pretty standard I guess. So there is a menu, some controls, and the main stuff below (ranging form graphs, tables, dropdown boxes, print preview, etc). I would like to use it like one would use frames in html, design an object that is limited to a box or panel that I define. The literature I have does not give me a clear idea of how to do this (yet). The most obvious seem to be the use of MDI, open a predefined form with no borders, maximize it before showing and remove all minimize/maximize options. But that does not work so well. The form inside the MDI parent does not fit the size that is given for it when it is loaded. e.g.
[CODE]:......................
So my main question is: Is MDI the way to go here at all or are there better/easyer ways to achieve this? If MDI is the way to go, how do I sucessfully restrict a child form inside another object, without giving the user any opportunity to resize (i noticed that I have minnimize/maximize/close buttons, even if I disable them on the child forms themselves)
If Class X is within the scope of Class Y, is X a subclass of Y?If Class A is a sub Class of B, then is Class B considered a super class of A?if Class C inherits Class D is Class D a superclass or parent of Class C?if Class E extends Class F then we can consider Class E a child of F?if Class G inherits Class H and is within the scope of Class I then who is the parent of Class G? Classes that inherits Class J and classes that are within Class J are all sub classes of Class J?

I have to Panels on a Form. The "upper" Panel is set to Dock = Fill the second "down" Panel is set to Dock = Bottom
Ok. - During the application I add some usercontrols in to the "down" Panel.
Now in one of the usercontrols, I have two group boxes (also set to Fill & Bottom) In the upper groupbox (Dockstyle = Fill) There is a Grid and below the grid, I have two RadioButtons.
On my developer machine, I can see the Grid and the Radiobuttons. On an other machine (other resolution, and other Display), I have the problem that, the RadioButtons are not visible anymore. - The user has to change the height of the "down" Panel by hand, so he can see the RadioButtons.
What I try to do now (and I don't get it working) is: Set the minimum heigt of the "down" Panel so, that both Groupboxes are visible and what is more important: that the commands are all visible.
calculate the height of the grid and the Radiobuttons depending of the solution and used display!?
