Total Posts: 1111 | Who here knows a decent amount about Visual Basic? I have a question: When the name of an object is stored in a string (in this case, let's say string "abc"), how can I use it as a substitute for the specific name of the object?
Example:
Button1 could be the object.
Instead of doing:
Me.Button1.Location = New.System.Drawing.Point(variable1, variable2)
I would like to do:
Me.abc.Location = New System.Drawing.Point(variable1, variable2)
or whatever syntax is needed.
I think it might involve abc.Format( in some way, but I would need the syntax for that as well.
I use Visual Basic.Net 2003, but help from any version would be quite welcome and helpful. Thanks!

I dropped Visual Basic, and picked up C++....
Brings back good memories though. :) |

Total Posts: 97 | Why are there so many members in these forums that are so petty? Are your lives so shallow that all you guys (I'm reffering to serveral members here -- not neccessarily just those who've posted within this thread) can do is go around pointing fingers at every imperfection you see?
Start worrying about real issues. I understand that it is not courteous to the mods/admins to post unneccesarily, but believe me: I'm not going to end-up being a postcount-happy spammer. I been there done that.
Of course, I will say no more in this thread so to not annoy the forum-gods (the admins). :)

Actually, I was asking for assistance with part of my final project for a programming class. That's pretty real, isn't it? As for pointing fingers, that's exactly what you're doing. You're not helping. I noticed that you posted and then edited your post, deciding that the first one was not insulting enough (no, I'm not just going by the "edited by stephendonnelly88" message at the bottom). Funny that your first post said "I will say no more", but you still did? There's a difference between imperfection and a completely pointless post. I really wasn't looking at imperfection in your first post as much as being technical with jessef.
If you weren't speaking of me, then never mind.

Insert a button, and change the text to Close, or to anything else that would tell a user that this button closes the program. Rename the button, too. Something appropriate could be btnClose. But you can name it whatever you want, like btnthisisthebuttonthatclosestheprogramwhenyouclickit. It's a bit long though and of little use for quick identification. If you rename all your buttons like this, you'll spend more time renaming your buttons than coding a program. Drag the button to an appropriate place. Don't forget to code it so that it closes the program. By the way, you can use the code as we did it in the previous article:
Private Sub btnClose_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnClose.Click
Me.Close()
End Sub
You can do that quicker, too:
Private Sub btnClose_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnClose.Click
End
End Sub
If that's not what you want...
Rename the temporary file by giving the same
'name as deleted random file.
Rename("abcdefg.tnt", TextBox1.Text)
this renames a file but will it work on a button?
If sorry if this doesn't help i tried :)

Total Posts: 1111 | How much time did you spend looking for that? I really appreciate the effort, but that wasn't exactly what I was talking about. When I said "Button1", I was just giving an example of an object that fit the description of what I meant. A lot of objects would fit.
I know all of the basics of Visual Basic and can code quite well (I'm one of the most advanced people in the class), but what I meant was being able to use the value of a string as a substitution for the direct text of an object's name. Yet another example:
Dim stringexample as String
stringexample = "TextBox5"
Instead of:
TextBox5.Text = "abc"
I would like to do something along the lines of this:
stringexample = "abc" and it would change the text of TextBox5.Text to "abc".
I am pretty sure this is possible.
By the way, the game I'm making is Chess.

Total Posts: 235 | ok i talked to my dad and he knew he said to use Addressof so i looked ot up...
VB 5.0 has provided a useful operator called AddressOf which returns the address of a function (there is no such operator in VB 4.0). It may be used only in front of a parameter when you call a function and uses like
FuncP = AddressOf MyFunction
are wrong and cause error. So, you must call EnumWindows like that:
Success& = EnumWindows(AddressOf cbFunc, 58&)
You must also write the callback function. There are different type of callbacks that have a different sets of parameters. Description of this parameter can be found in a SDK Help file or MS SDK documentation. Here is the declaration for the callback:
Public Function cbFunc (ByVal Hwnd As Long, ByVal lParam As Long) as Long
Here is a sample of callbacks:
(paste this code in a module, as callbacks should be Public)
Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Declare Function EnumWindows Lib "User32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Public Function cbFunc(ByVal Hd As Long, ByVal lParam As Long) As Long
If lParam = 58 Then 'enum windows
Dim St As String
St = Space(255)
Ret& = GetWindowText(Hd, St, Len(St))
Debug.Print Left(St, Ret&)
cbFunc = 1
End If
End Function
(paste the following in a form module with a command button on it)
Private Sub Command1_Click()
Success& = EnumWindows(AddressOf cbFunc, 58&)
End Sub
Note that the function returns 1. If it returns 0, the enumeration will stop. Watch the Immediate Window.
This sample enumerates the captions of all (literally) windows (no childs).

hope that helps! good luck :)

Total Posts: 1111 | Just updating everyone on the progress of Chess... Didn't know that it counted as triple-posting in that way. By the way, I'm done with the main game! All that's left is:
Detecting check (even now, if you take the king, the game's over)
Castling
En Passant
I know it's not the biggest accomplishment ever, but I still think it's pretty good for only programming in Visual Basic for 4 months. I'll have a download link when it's all done.

Total Posts: 1111 | Wow. Chess isn't as hard to make as it is time-consuming! I've spent a week doing it. Both kings are able to castle on either side. I've gotten pawns that have reached the other side of the board to turn into queens (yes, I know they could be bishops, knights, or rooks as well, but queens are best and save time). It's all fully-funcional with no glitches that I know of. The final version may be <a href="http://www.ucomics.com/foxtrot/" target="_blank"">foxtrot</a> oriented, but it's getting finished quickly.
Edit: Almost done. Nothing left but "en passant".

Total Posts: 1111 | DONE! I posted a link to it earlier today, but I did en passant wrong and fixed it. Here is the real version: http://www.geocities.com/plipperson/Chess.zip
One thing, though. It doesn't automatically detect check, which makes it stealthly and hardcore : ). You win by taking the opponent's king.
Please post any bugs you find. I currently know of none.
