Retrieving What Image Has Been Dragged To A Picturerbox?
May 26, 2010
I�m having trouble with the picturbox control, my problem in its basic form is:I have a picture Box array consisting of 9 picture boxes each with a different image in loaded at run time these are names 0.jpg to 8.jpg I then have 2 more picture Boxes named ansOne and ansTwo. I have made it so you can drag the images of these numbers to either of these picture Boxes It this next part I�m having trouble with:
I then want to have thoughs images represent a sum so when a button is clicked it adds or multiplies thoughs images together but as numbers ("badly put I know ")I am very unshore of where to start. After the image has been dragged how would I know what image has been dragged and turn that in to its integer equilivent?I had thought of using split string or something similar to just get the number before the .jpg so tried picAnsOne.imageLocation but that throghs a null reference And that�s as far as I have got.

I have completed my vb project and have created the set up files as well.. Now when I try to install my program on another machine then it gives me an error. I found out the problem and it seems to be two of the images are not loading even though i have saved them in my application folder.. But when i save them in the resource folder the program runs but does not displays the images stored in the resource folder.
dim tick as image
tick = My.Resources.ResourceManager.GetObject("button-tick.png")

i have been in state of hectic for the last 2 days making lot of research and finally made this code worked it for me. My problem is that, how can i make this code retrieve the image from sql server database...use picturebox to load it in the vb.net program.
Dim myfilelocation
As
String =
"C:myPicturesmyimage.png"
[code]....
Is it also possible to change the location of image where its getting the image. i mean, i would like to tell other computers to get their images from anywhere as long as it brings images to my server.i mean, say that comp1 which is connected to my database server for storing and retreiving information, gets his image from his location then the application sends the image to my server...the application retreives the image from the server..as simple as that.

I have manage, to allow user to browse through their files and insert an image path into a local database. The program will then retrieve the image from the image path and will be stored into ImageList. The Listview1 will then add the pictures of Imagelist into the ListView1.Items. Now my question, how can i retrieve back the path of the image when the users click on the selected image from the ListView?

I have created a list form that gets attached to a main form in VB.NET. This all works fine except that when the main form gets activated, I need the list to be brought to the front as well. I have put in a simple IF function to do this but when I added these lines of code, the main form, as well as the list form now do not get brought to the front until you let go of the mouse button. Obviously this means that if you drag the form, it stays at the back until you let go of the mouse button.
The code that I added is below:
If CRL.Visible = True Then
CRL.BringToFront()
End If
CRL is the list form.
If I comment out this code again, the main form get brought to the front while dragging but obviously the list form does not. The main form as well as the list form are MDI children.

I'm working on a music player (I'm a beginner), I've gotten the basics down but I've been stuck on something for the last few days.
I'm wanting to have a listbox that (only) music files can be dragged onto, once they are dragged onto it I want the listbox to add it as an item on that listbox. So basically, I'm wondering how to drag items onto listboxes, restrict that to only music files (specifically .wav & .mp3) and have that dragged item be added to the listbox.
PS. I'm making this media player myself, without WMP or DirectSound (I believe it's called).

How do you accept dragged text to a notifyicon control? I am aware that the notifyicon control supplied with .net does not have an AllowDrop property nor does it have dragenter or dragdrop events. I'm looking for a way to somehow do this without reinventing the control.

Trying to replicate the docking controls in Visual Studio 2008. My application replays the RADAR environment for the FAA and I want the ability for dual monitor users to drag the control panels to the other monotor to leave the main canvas clear. This functionality is similar to the way the different panels in VS can be dragged outside of the main window.

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.

I want to achieve the following:
The user drags text from any open window not related to my application ( like firefox or word, for example) onto button1 on form1 in my application. when he/she does that, a new form (called form2 that contains a richtextbox) will open and the dragged text is directly copied (or inserted) into the richtextbox of the new form. button1 has allowdrop set to true. Beyond that I don't know how to proceed.
I tried:
e.effects = DragDropEffects.Copy
But it seems it is not enough.
