Dave, this could truly be a moment in history. I believe that you've been more derisive than me on the same thread :P I've sure tried to answer in a way that's helpful and expose my bias.

That's why you're a programmer, and the people lobbying Microsoft for continued VB6 support will never be.

 I still, to this day, can't understand why that petition was started by/signed by a bunch of MVP's!!! This boggles the mind!!

Yeah, it's got me beat as well. Although, an MVP is someone with expertise in one area, and who is willing to share it. There's no reason why someone who knows VB6 well and likes to help people is guarenteed to also be willing to learn something new.

Go with VB.NET 
I went from C++ --> C --> Java --> VB6 --> VB.NET and C#
I kept jumpping around till about VB6. In VB6 I was able to make quick and simple apps with a GUI. The minute I tried VB.NET I pretty much forgot everything about VB6 and have never looked back. The new .NET languages just make it so much easier to create a user interface and then have more time to work on backend things like data storage, validation, and reports.
Plus, VB.NET and C# are pretty similar, so once you learn one you'll be able to understand the other
So, give it a shot and see what you think.

You went from C++ to C ? Why ? How did you end up with VB6, did you actually learn to use C++ with MFC ? That's one odd migration path IMO

Yeah, that's mostly true, although knowing VB6 AND C++ would give you a head start in terms of the differences of syntax. I've done VB.NET work ( although I refuse to do it again ), and I found it pretty easy, except that the syntactical differences still catch me.

Well, it's cause I started learning C++ at the beginning of my senior year of high school and when I got to UCSD I had to start with C and work my way up. After some time at UCSD I just wasn't cutting it so I left for a community college and they had Java. After Java the only other computer programming class was VB6, so I did that and loved how simple it was. I could whip up a quick GUI to go with my code; stuff that would have taken forever in the other languages (at least for me since the classes and books covered concepts and the console window but not how to make your own GUI). Then VS2002 came out, I saw VB.NET and C# and said this is what I've been waiting for
So I tried a bunch of languages in about a 2.5 year period and finally decided that .NET is the way I want to go. I mainly use VB.NET because it has better intellisense support than C#; for the moment anyways. I also like C# because it has the GUI creation of VB with the coding style of C/C++.
Can't wait for VS2005 Final. Maybe if the intellisense is better for C# I'll make the final switch and just stick with C#.
It wasn't till I started learning .NET that I was finally offered a job as a programmer. It started as a normal convert our old apps to new apps but has now gone to custom control creation (fun), database interaction (ok), controlling office through com (hate it), ASP.NET (hate it, VS is always messing up my pretty html code so I have to be careful when switching between webform view and html view so that I can undo it's auto-format), gdi+ graphics rendering (lots of fun), and creating pdf files (was fun at first, but now becoming a pain since the company wants EVERYTHING to go directly to pdf and with minimal user effort, which means WAY MORE work on my part).
Hope that explains my odd migration path

OK, that makes sense. I thought you'd worked with those languages in that order, professionally

VS2005 won't mess with your HTML. In the meantime, never use the design view. I work every day in ASP.NET, have since it came out. I've never used it, for that reason.

Hi, I have been using google to find a way to count all controls and go trough them to find all the TextBox controls and put them into an array of TextBoxes.
I can't seem to find any good way to do this so I was thinking of making a function to count them, but I get an error I just can't get around it seems.
This is how the function looks like:
Public Function GetControls(ByVal cControl As ControlCollection)<br />
Dim iControls As Integer<br />
For i As Integer = 0 To cControl.Count - 1<br />
If TypeOf cControl(i) Is TabControl Then<br />
MsgBox(cControl(i).Name)<br />
GetControls(cControl(i).Controls)<br />
End If<br />
If TypeOf cControl(i) Is TabPage Then<br />
MsgBox(cControl(i).Name)<br />
GetControls(cControl(i).Controls)<br />
End If<br />
If TypeOf cControl(i) Is TextBox Then<br />
iControls += 1<br />
End If<br />
If TypeOf cControl(i) Is Label Then<br />
iControls += 1<br />
End If<br />
Next<br />
MsgBox(iControls)<br />
End Function
I call the function with 'GetControls(tcMain.Controls)' there tcMain is an TabControl object and all I get is this exception 'System.InvalidCastException'. When I try to call the function with 'GetControls(Me.Controls)' it get it right and count the controls on the form, but when the function finds a TabControl object I get the same exception.
Anyone got any idea what I made wrong, or have any tip on how I can count all controls and "child-controls" I would be more then happy!
Thanks on beforehand! /Joakim

have you tried this:
dim count as integer = 0<br />
for each c as control in me.controls<br />
if typeof c is textbox then<br />
count +=1<br />
end if<br />
next<br />
<br />
messagebox.show("There are {0} textboxes.",count)
that will NOT check other container controls such as panels, groupboxes.
Hope that helps!
Thanks for firing me Darrell Eaker. I TRIPLED my salary and don't have to deal with morons like you.

Well yes I have tried that sorta, and I have all my textboxes in a TabControl with multiple Tabs so I need to loop trough all controlcollections to find all the controls, and thats why I made the function to loop trough all object that has controlcollection like TabControl and TabPages.
Thanks for you reply tho. /Joakim

Do it recursively - write a function that takes a control and iterates through it's children, and have it call itself for the control collections as it steps through.
function CountTextBoxes(ControlCollection controlCollection, int count) returns int ' Whatever the VB syntax is
for each c as control in controlCollection
if typeof c is textbox then
count +=1
else
count = CountTextBoxes(c.Controls, count)
end if
next
Then you need to do something like
int count = CountTextBoxes(myControl.Controls, 0)
messagebox.show("There are {0} textboxes.",count)

Dunno why but it doesn't work for me...
Check out this test:
<br />
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click<br />
<br />
Dim ctest As ControlCollection<br />
ctest = Me.Controls<br />
<br />
End Sub<br />
This works.
<br />
Private Sub cmdTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdTest.Click<br />
<br />
Dim ctest As ControlCollection<br />
ctest = tcMain.Controls 'tcMain is a TableControl object<br />
<br />
End Sub<br />
This doesn't, all I get here is a casting error.
Anyone know why?
/regards Joakim

That's weird, because that is a ControlCollection. Is that all your code ? What line blows up ? If you can give me some html, I can do a test here.

Yeah I know, I made another test just to check that there was no other code in my program that was messing with this function.
So I made a fresh start, standard windows app. with a TabControl with 2 TabPages, then I added 2 TextBoxes and 1 Label to each TabPage, and a Button on the first TabPage. and then I added this code and get the same error.
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
GetControls(Me.Controls)<br />
End Sub<br />
Public Function GetControls(ByVal cControl As ControlCollection)<br />
Dim iControls As Integer<br />
For i As Integer = 0 To cControl.Count - 1<br />
If TypeOf cControl(i) Is TabControl Then<br />
MsgBox(cControl(i).Name)<br />
GetControls(cControl(i).Controls)<br />
End If<br />
If TypeOf cControl(i) Is TabPage Then<br />
MsgBox(cControl(i).Name)<br />
GetControls(cControl(i).Controls)<br />
End If<br />
If TypeOf cControl(i) Is TextBox Then<br />
iControls += 1<br />
End If<br />
If TypeOf cControl(i) Is Label Then<br />
iControls += 1<br />
End If<br />
Next<br />
MsgBox(iControls)<br />
End Function<br />
No idea why it wont work, looks like TabControls don't use the same ControlCollection as for example TabPages or something like that.
Thing is that I like to make this function dynamic so I can use it in any situation to check for Controls in an ControlCollection.

and here is a html with a rar on the testproject >WindowsApplication1.rar<
the line 165 crashes in this example, when it tries to call the function with a TabControls ControlCollection.

You seem to be right - the TabPage AND TagControl have TabControl.ControlCollection and TabPage.ControlCollection collections, you need seperate functions to pass those objects to and iterate through. What a disaster.

I think you making it harder than you need to.
For each tabcontrol there are tabpages which contain the controls your trying to count.
Function CountControls(ByVal tPage As TabPage)
Dim count As Integer = 0
Dim c As Control
For Each c In tPage.Controls
If TypeOf (c) Is TextBox Then
count += 1
End If
Next
Return count
End Function
Simply pass in the tabpage you wish to count the controls on..
Debug.WriteLine("Total textboxes: " & CountControls(TabControl1.TabPages(0)))
Hope this helps.

Sould read... sorry
Function CountControls(ByVal tPage As TabPage) as integer
Dim count As Integer = 0
Dim c As Control
For Each c In tPage.Controls
If TypeOf (c) Is TextBox Then
count += 1
End If
Next
Return count
End Function
|
|
|
|
|
Aye, I have done that now, but I want to make this function more dynamic.
So I could pass Me.Controls to the function and get refs to all TextBoxes for example.
