Why is it ? Because it's good to know that there are people worse off than you ? VB6 was always crap, and it's been unsupported for some time. VB.NET would be a lot less like VB6 if a bunch of MVPs had not revolted, MS knew they had made a mess, and were looking for a clean slate.

Not really, just brings up memories. I don't have it installed at home pc at all anymore, but no matter what, VB6 was and i could say still is most complete of them all. .Net for me is far away from complete. Speed? VB6 is much faster, it might have simpler GDI, etc.. but speed is much better than in .Net (for controls, not it's actual computing speed), it was simple and anyone could use it, was perfect for learning. Since Vb1 for dos i was using it, it did not give all those fancy stuff like most other languages in that time did have, but, sure was better than delphi (or pascal, depending on era). It's just that it was compact, and runtimes ware small. And it always did his job.

Not only that, in VB6 a lot of times one would depend on APIs, now, with .Net, programers don't know what are APIs, they don't know there are windows dlls that give us some nice features, it's all managed now, so no one dares to subclass anymore. People underestimate VB (pre-.Net), it really was not that bad.

And IDE? .Net is so slow, while VB6 did have really fast IDE. Sure, it's much nicer to programm in .Net, it's nice to write OO code, also saves me hours of work with all built in functions. But, also, it makes me more ignorant, before i would write algorithams, now, if i need encrypton, i will just use the one built in, while in VB6 i wrote 10 algortihams by specifications, it was so much more fun. Servers? I now have a class with all this, but before when i was making SMTP or IRC server, i did not read MSDN, i would read specifications of windows API. So much more fun, now, it's only coding with what we have already inside, thats good, saves us time, but the fun factor is gone.

If I were you, I wouldn't be smoking that stuff any more. It is imparing your judgement.

Seriously? You want to hand craft your own encryption algorithms? Personally, I have much better things to do with my time (and my company's time)

By complete what i did mean is, you never know which classes will change, which was a problem from moving a 1.1 to 2.0, since half of them became depricated. Was not necessery to do it, but sure its what they suggested.

Oh, i will sue that cigarette company, i always knew they put some illegal substances in those cigarettes Big Grin | :-D

Sure, everyone does, but you don't get to do cool stuff anymore, you are forced to use it, since it's alrady in there. There is no programming involved anymore, you just use the classes that are supplied with .Net framework. Where is fun in that? And you can not write your own, since boss will yell at you and tell you it would take to much time and would gain nothing.

Well, you are right. VB 6 isn't going to change because Microsoft finally stopped supporting it last year.

Enver Maroshi wrote:

I would suggest that is hyperbole. A small number of classes were deprecated. Nowhere near half. And you can still use these classes, just be aware that they won't necessariliy be supported in future releases. (Just as VB 6 is no longer supported)

Enver Maroshi wrote:

I suspose they didn't have to tell us the classes were deprecated, but it should would be a shock to install a shiny new version of .NET to discover they weren't there any more.

I have a lift in my apartment building, I also have stairs. I'm not forced to use the lift, I can always take the stairs. However, I use the lift becuase I'm several storeys up and it is easier to carry my shopping that way. Just because you have encryption classes doesn't mean you are forced to use them, although you'll find things much easier if you do.

There is actually quite a lot of programming involved in a business application. Most of the fun is in delivering something that has value to the client.

Your boss is correct.

But i can say for sure that writing code 10-15 years ago was much more fun than it is now. Poke tongue | ;-P

So, you say that also no one should use c, assambler, etc... anymore?

VB6 is designed for writing business applications as is C# and VB.NET. If you are in that area then it is one of the good choices open to you.

C and assembler are designed for writing operating systems, hardware drivers and embedded systems. If you are in that space then VB6 or VB.NET are not good choices.

If you want to spend your time writing low level code then get a job doing that using C or assembler. If you want to write business applications then VB.NET, C# and Java are the kind of languages you should be looking at.

Enver Maroshi27-Jun-09 3:40

Not the answer to your question

27-Jun-09 3:40

What i meant by referring to c and assembler is that they are also not supported, could nto be, it's just language, not a product, like VB6, but compilers for them which people use are in most cases 10 years old, and they still do the job. So, VB6, or basic language in its pre-OO age is still working and is funcitonal (well, maybe win7 does not support it). So, it is no more outdated than any other. But all of this are "complete", it's in stable state, and nothing changes.

Now, in .Net we have something predefined which can change at any time, while in old VB6 you did have commands, and that is about it, something which did never change, just new ware added up over years. While .Net brings a lot of classes with each release of new framework version.

I use .Net, and sure it's 10 times easier to write code in it, for a "real" project would not go to VB6, since its all much easier to be made in VB.Net.

Why did i mention VB6 in first place? Well, back then VB programmers did have it's language, IDE and good support. VB.Net? It's got nothing to do with VB, really nothing, it was MS evil plan to make C++ and VB programmers think same way, and so we do, anyone who can work in VB.Net can work in C#, and vice versa.

So, what happend is not that VB evolved, he is gone. Why did i say it's nice to see someone still using VB6? Well, if anyone wants to use, go for it, vb6 is not bad, never was, and it's last real basic Roll eyes | :rolleyes:

And those that did not work in VB6 might think that it sucked, but, my opinion is that it was maybe to simple for those that used C++ or something similiar. You could do all what one could do in C++, or C, except that it depended on runtime (but so did VC++).

Oh, that is a long post. What i want to say is, if someone wants to use VB6, don't tell him not to. I'm sure he does know that VB6 runtimes will not come with never versions of windows.

Btw, embeded systems? os? This is already possible using .Net (not all classes suported yet) OMG | :OMG:

If you are developing a new application, why VB6? Ages before .Net was released and is quite powerful (which you already know).

placing a control on the panel

hi,

i have a panel ,when i move the cursor on to the panel,i should get the cursor position i want to know the location of the cursor and place a control on the panel.

Christian Graus25-Jun-09 21:46

25-Jun-09 21:46

Which part are you stuck on ? Capture the mouse move event, then work from there.

Enver Maroshi25-Jun-09 21:59

Re: placing a control on the panel [modified]

25-Jun-09 21:59

Double click panel, choose mouse move event and click on it and you will get somethign like this

Private Sub Panel1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove
' e.X and e.Y are available
End Sub

To add control inside use something like this

Dim NewBox As New TextBox
NewBox.Location = New System.Drawing.Point(e.X, e.Y)
Panel1.Controls.Add(NewBox)

Just put this add control stuff into mouse up or something, or add it on mouse down, move control as you move mouse and release it on mouse up

This is basic stuff, try to read a book or two.

I can added images on panel where ever i want.But now problem is one image is overriding other image .i don't want to be override .

26-Jun-09 21:43

What exactly do you try to make? What is a role of this application?

Maybe there is some other control that suites you better, if you need to drag-and-drop images, why not do it in listview? There you would be able to drop images, also to re-arange them, make a preview of them, etc...

"But now problem is one image is overriding other image .i don't want to be override ."

Well, then you would need colision detection Confused | :confused:

What should happen next? If you try to release image on other existign one? Should cancel drop, or maybe move next to picture? Best you could do is loop through each image in panel and see if they positions match at any point.

hi i too have the same problem
but the problem is like this

i have two picture boxes and a panel.
one picture box has a image and another picture box image is none.

i can drag and drop the picturebox1 image onto the picturebox2

now i did the same drag and drop to panel with slight change

if i drag and drop picturebox1 image on to the panel at any place on the panel then at that location i should add the picturebox1 control

please any one can help

i think i m confused and didnt explained u clearly...

Christian Graus26-Jun-09 0:51

This sort of code is almost always improved by dropping the picture boxes and instead writing your own code to put the images on your form, where you want them.

Christian Graus25-Jun-09 21:46

Webrequest and Querystring in VB.net

25-Jun-09 21:46

yes, of course it's possible. Most encryption/decryption uses standard known algorithms. So you need to find an algorithm that you have an implimentation of in perl and in VB, or you need to write one.

your subject line is ridiculous. Everyone here wants help. Try putting something that means something.

I am very new to web development and i am finding difficulty with webrequest and querystring in vb.net.
I am working on an application which will pull data from a URL. The data will come with 2 variables. "from" and "text" that is the sender of the data and the text of the data.
I have a desktop apllication which is supposed to read this data from the url and i am pretty lost here.

how do i use webrequest and/or querystring to read the data from the url and pick the two variables.
for instance i want to read them like this

Dim message_originator As String = context.request.querystring("from")
Dim message As String = context.request.querystring("text")

I don really know what to do to read them as above into the variables.
Any help please guys? Confused | :confused:

Try
Dim objNewRequest As WebRequest = HttpWebRequest.Create(sURL)
Dim objResponse As WebResponse = objNewRequest.GetResponse

Dim objStream As New StreamReader(objResponse.GetResponseStream())
sOutput = objStream.ReadToEnd()

Dim message_originator As String = context.request.querystring("from")
Dim message As String = context.request.querystring("text")

'place code to read specific string token you need here
'for example code to insert into database etc. just see what you have in the
'string if fetch was successful and then you'll know how to readi specific string

Catch eUFE As UriFormatException
sOutput = "Error in URL Format: [" & sURL & "]" & NewLine() & eUFE.Message
Catch eWEB As WebException
sOutput = "Error With Web Request: " & NewLine() & eWEB.Message
Catch e As Exception
sOutput = e.ToString
Finally
MessageBox.Show(sOutput)
End Try

You're doing a post to a URL and looking for the query string on the response ? That sounds weird to me. Any change of URL is a new request/response, I'd have thought.
