I'm trying to create copy in a menu however i'm having trouble to get it to work as i want it to. I've seen many tutorials online that have 2 textboxes and the code to the copy control is simply TextBox1.Copy() and paste is TextBox2.Paste(). This is fine but what about when you want to copy from TextBox2 to TextBox1 or when you want to copy only part of the highlighted text? Does anyone know what i can use to get it properly working?

This is probably a really basic question - but I have a list of items (custom objects) being passed from one winform (.net 3.5) to another. I want to create a local list to store changes that only get persisted if the user clicks save. Currently if the user clicks cancel - the changes are still applied in the first form because I assume the objects are reference type.I have the save working as it calls a service layer to do the save and then refreshes the other form - but not the cancel.
View 1 RepliesIn .NET, the Generics Lists have a sort function that accepts IComparer or Comparison. I'd like to sort just part of a list. Hopefully I can specify the start index, count of elements to sort, and a lambda function. It looks like you can only use lambda functions to do this if you're sorting the entire list. Is that right or did I miss something?

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

I am using visual studio 2008 (vb.net). I have a long list of file names in column A on an excel sheet. These files are located in a directory on my network drive. I have to copy these files over to another folder. I know how to copy files in vb.net, however, I need to copy the files listed on column A.

I am sure this is a simple question to the more advanced, however, to the less advanced I am having a problem. I have to come up with a quick program (that works) for my job (I am a systems admin) that will either look in a database or excel sheet (which ever is easier) and find copy files from one directory to another. I know how to move, copy and delete, however, I need it to look for the specific filename.

View 3 RepliesI have a WPF form that takes a list of objects that have locations and sizes and plots them on the canvas. I'm currently trying to implement an undo button that will throw out all the changes that have been made to the positions of the objects and revert back to the original collection that was retrieved when the form loaded.
As it stands now I go out to the database on the load of the form and get all the objects that will need to be displayed then assign the list that is returned to two seperate collections. The problem that comes up is that the two collections are actually pointers to the original collection and whenever one is changed the changes are reflected in the second collection.
Is it possible to copy a list of objects so that changes made to one collection won't affect the secondary collection?
So far I've tried simply using the assignment operator, passing the source collection into a function byval and scrolling through each element of the list manually adding it to the second collection and using linq to get all the objects from the original list and pushing the results to a separate temporary list and assigning the second collection to the temporary list.
I feel like I'm overcomplicating the issue but almost all the places I've come across while googling say that this behavior is by design, which I understand but it seems like this would be a fairly common idea.
I understand I've been asking alot of similar questions around this topic, but I think, with luck, and your help, this will be the last time.

If I have a generic.list(of ClassA), is there a simple way to create a deep copy of this list that will not affect the original copy? It seems to work if I have a generic list of Structures, but for some reason the copy constructor for lists of classes only copies pointers to the elements (or maybe a pointer to the whole list?). I would move to structures if it were not for the fact that I can't find a way to edit the members in the structs in the list. eg:list(0).a = 5 'Does not workIs there some way to get around this without declaring an instance of that structure, like this:dim str as StructA = list(0)str.a = 5I'd

I want to see str1 as "ABC" but the out put i get is "A B C" (ie with spaces between letters) note: I have to copy(chunks) within a loop and get the result at the end, this is just a sample to reproduce my real issue.
In my project when someone logs in I refresh the overhead and side menus. My overhead menu is an extended menustrip component that I have made. I am able to clear the menu, reload it dynamically but I am not able to add/insert the open windows which are managed by the mdiwindowlistitem property. These are the items named "1 - form name " "2 - form name" etc.
I have been able to copy the whole dropdown list, and with some very hacky loop work I can take out everything but the items related to the forms. But when I add them back in, they are not on my list. The related forms are still open and if you click the maximize button to shrink a open child window, and then re-maximize that same window...the items magically show up in the list.
This ManageMenus sub is called during a login change. If you breakpoint on "openwindowslist" after it is returned with data, it has the proper entries and nothing extra. It just seems that the for/each add loop does not actually add the items. Or, if it does add them, I can't see them.
Tried both insert and add functions, same results both ways.

In my xmlMenuStrip component this is the function that removes everything but what follows the seperator. It returns them in a list.

I am having a problem when setting VB.NET list object to another.I create an instance on ReadLocations and than create an object of ReadLocation where then I loop through ReadLocations and set ReadLocation1 equal to rl. What happens is that if I then go and change ReadLocation1 to something else (assdfhsd) it will also change the ReadLocations index. I am really confused why it would be doing that unless it is "=" sign means referencing instead of actually setting the value.

View 1 RepliesWhat I am doing is iterating through all the groups that belong to the top group (Generic reports). Then I take advantage of the GroupPrincipal.GetMembers(True) which will recurse through a given group name. I test to see if the user exits under that group and if true I put the group name in an arraylist.
I use the for each principal in GroupPrincipal.GetMembers to loop through each returned user to see if they exist.
Is there a way to put all the returned users Principal.Name from a given group in GroupPrincipal.GetMembers into an ArrayList? This would allow me to to use Arraylist1.IndexOf to search for user. Which would be much faster then iterating through a returned list using the for each construct.
