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.

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.

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

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...

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.

is it possible
to encrypt data in VB.net and decrypt the same in perl script
(if yes tell me a way to do this)

Re: help me

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:

How is the web request getting into a winforms app ?

king gamo25-Jun-09 18:54

25-Jun-09 18:54

i use the following to get it but i don think its right.

<
Public Sub GetNewMsg()
Dim sOutput As String
Dim sURL As String = "http://www.something.com/noticeboard"
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

End Sub

Is it possible for you to write a small function that accepts data from a url into a winforms app the right way cos mine is just not working!

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.

king gamo25-Jun-09 19:44

Christian,
I am really lost in what i am doing. Please if u can help me out with retrieving from the url where i can access the query string, i will be able to continue from there.
thanks

Christian Graus25-Jun-09 19:49

25-Jun-09 19:49

I honestly don't think this is possible. There's nothing on the query string when you send it, so I don't expect there will ever be a querystring on the response. I think you're barking up the wrong tree.

king gamo25-Jun-09 19:51

25-Jun-09 19:51

please so how do i go about retrieving the data from the url then from my winforms app?

Christian Graus25-Jun-09 20:08

The only data on the URL, is the data you put there. This is the core issue here, which is why I said you're totally lost. What makes you think the URL will change when the data is posted back to you ?

Sounds like you are confused about request and response. You get query string only when you are getting a request. Assume you are writing a HTTP server and someone requesting to your program with query string, you will get it. In your case, you are the one who is requesting and you only get a response which won't have query strings. You will get the output of the URL you requested.

Or did I got your question wrong? Smile | :)

You got my question right. Now my problem is how do i get the data from the url? the winforms app has to read from the url whenever data is pushed there by a sender.

It is not who i am underneath but what i do that defines me!

Christian Graus25-Jun-09 20:05

25-Jun-09 20:05

We're both saying the same thing. The URL will not change, so there will be no query string data. Have you run this through the debugger ? The URL does not change, between a request and a response, which is what your code does.

king gamo25-Jun-09 20:15

25-Jun-09 20:15

Thanks guys i get u but is there a different way i can use to achieve what i want to do please.
Ok a remote server will be posting data to the url for me to read. I have setup the url like http://www.myownserver.com/noticeboard
They will be pushing the data here for me to use. I dont know when the data will be available but i know the variables. 2 variables will be available for me, one for the sender and the other the text named "from","text".
Is there a way out. If its impossible then i think i have to go crazy now cos i really need to do this.
Is there any other way in vb that i can use or it is not possible in vb.net?

VB.NET has nothing to do with it. If you wrote the site, then push the data you want back, inside the page. Or better yet, ditch this rubbish and write a web service.
