VS 2010 File Dragged Onto Listbox?
Mar 4, 2011
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).

I'm developing an application in vb.net. You drag any type of file onto the exe, and a window pops up with some options for the file, then it saves the file to a different location, works some SQL magic, etc. It works great for the most part. The only issue I've found is that if the path of the file contains any spaces, the application will crash immediately with the error window:[URl]..I'm using: Private filename as String = Command$ This is located right inside my form's class declaration, not within a sub/function.Without this line, my program runs fine (although useless, without accessing the file).I've also tried (I think this was it, I don't have the code with me at the moment): Private filename as String = Environment.CommandLine So, in vb.net, is there a way to drag a file onto an exe and use that path name, even if there are spaces in the path name?

I need to run my program as admin because it accesses the registry on load. Well I wanted to implement a drag and drop feature but have come to find there is a access issue with running as admin and the dragenter event. Is there any known workarounds for this? I have searched all over the place.Just a side note I only need to get the file location from the item being dragged in...

I'm trying to get a random line of text to appear in a messagebox upon button click, I want the listbox to be closed while the action is to be performed.
I can do it when the listbox is open but not when closed, here is what happens if I try to do it when it's closed
and the message "InvalidArgument=Value of '0' is not valid for 'SelectedIndex'."
I tried reading it straight from the .xml file the data is stored on, but that didn't go so well either.

[code]I have one button to play all the stuff, but it needs the full path to the mp3 file to play, but I only saved the File name to the Listbox.So basically, I'm wondering how to be able to still select files in the Listbox and press Play, when the Listbox's Items do not include the full path to the actual files.I know I could just add the full path to the listbox from the beginning, but I don't think that looks good.So maybe someone can point me in the right direction, or maybe provide me some source code.

I'm studying VB 2010 at uni and struggling with this assignment, I'm stressing now with one week to go before its time to hand it in and still not knowing how to do it (even though i've read the whole textbook!)
I have copied the instructions and the files I have been given.
1 List all of the data from Teams.txt in a Listbox. Include suitable headings.
2 List all of the data from Results.txt in the Listbox (use the same Listbox as in 1 above). Include suitable headings. Note that you cannot assume that the file contains only results for the first 3 weeks of the season. Your program should be able to process a results file with more or fewer results.
3 List all of the data from Results.txt in the Listbox. However, in this case the actual team names should be output (your program will need to get this data from Teams.txt. The data should be formatted so that it is aligned correctly. Include suitable headings.

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 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.

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.
