if I have an image in the dictionary that is pulled in from the RESX file..... my code replaces some if a name match occurs. imgDct(dKey) = Image.FromFile(aFi.FullName) so, now the dictionary has a file pulled in. it seems that this LOCKS the original file? so i cant edit it.. and replace it is there a way i can pull the image in without "Locking" the original?

If I wanted to omit certain list items against arbitrary keys (that is the items that are in the list contained within the value part of each of the key value pairs making up the dictionary) given some arbitrary condition (lets say omitting list items where a list item contained the string "abc")
I would expect to able to create/project into a new dictionary which would contain entries which contained lists WITHOUT those items whose name contained "abc"

I have a image with a transparent background. I clone it, rotate it, and save it in a picture box. Works fine (in that I can see the original object overlaid on the background image below it). However, the original unrotated image is also superimposed on the .image layer *with* the rotated one. Try as I can, I can't stop it from appearing.
Curiously enough, if I change the image to non-transparent (a .bmp instead of a .gif, for example), I don't have the problem. Of course, I also can't see the background {:<(

View 1 RepliesI currently have a picture box and it has a MouseHover event. When the picture box is hovered the picture will change images. But when it is not being hovered upon I need the picture to switch back to the original image. Is there anyway to do this.
Currently I have:
Private
Sub picOpen_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles picOpen.MouseHover
picOpen.BackColor = Color.White
End Sub
The object is to load an image into a picturebox, then save a new copy of the image in a different location, but with the height and width of the image box not the original file's height and width but I can't figure it out. I've got the loading and saving working no problem but getting it to adopt the new size is stumping me, it just keeps saving with the original file's size properties

I am writing an application that I want to give to a select number of customers.
What is the best solution to use so that after the trail period (1 month) the application will no longer work.
I was thinking that if they are interested in purchasing the software I will give them a license key or something, to unlock the application. However, I would like to make this unique to every computer.
I am have a very limited budget as I am working on my own. So is there any free 3rd party products that does this?
I was thinking of writing the date the application was installed in the system registry, and each time the application loads it will check if this date is over one month. However, the user could turn back the date on their computer.
Another, solution I was to have the application run some many times. For example, the user can only run 30 times. Then it will lock.

View 2 RepliesI want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

I have the following object:
countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))
The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:
groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)
The best result I could get was:
Lookup(of MasterCategory, Dictionary(of Date, Integer))
From:
countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)
Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.

3. get the page source (I already use the browser.document but I'd like to retrieve it from the get request).
I've got two programs, one is the main and the other is the updater. So far iv'e got it so that the main program checks for an update by comparing its version number with the latest one that's stored as a text file on the server. If there's a newer one, the update program is started and the main one closed. The update program will then use a web browser component to navigate to the download link and download the new version. The only problem I'm having at the moment is, How can I get the new downloaded version to replace the current one in Program Files? and will this cause permission problems?
