Im currently trying to build a treeview from data like:
a.b.c.d
a.b.c.e
a.b.c.e.f
a.b.x
Which im trying to build into a tree like:
a
b
c
d
[code]....
(So splitting at the .)However, im havign trouble getting the tree to work properly..Ive tried like creating a root node, then splitting each line of the input at the dot, but i just cant get it to work right.
I am really stugling with this an was hoping that someone has done this in the past and can lend some guidance, I have had a look on Google but I only seem to find examples of one parent and one child.Anyway back to the problem, I have a treeview on a form and I want to allow the user to create a tree structure of their choice. What I mean by that is no limit to parent and child combinations, so basically have the same functionality as in Window Explorer.Now comes the problem, what I want to be able to do is store this tree view hierarchy in a database, so that when they add a new node to the treeview it is stored in the database at the correct level. Then if the user closes the form and re-opens it loads the treeview hierarchy from the database.

I am trying to dynamically build a TreeView. I want to be able to expand a top level node & have any child nodes be added on the fly. The problem I'm running into is that I can't get the "+" symbol to appear if there are no subnodes to begin with. I could probably add a "dummy" subnode, then when the parent node is expanded I could delete the dummy node & add my real nodes, but that sounds cheesy.

View 1 RepliesIm currently working on a major project for school that i can keep track of customers, giftcards, and primarily appointments. My current issue is how im going to build the weekly schedule page. I dont even know where to start with the ui let alone coding after that. Once i can figure out how im going to build i should be able to finish it from there.
Primarily its supposed to take info from the SQL database i have setup and from there populate the schedule on the screen. Its supposed to be like a weekly schedule with 15 minute blocks from 9 am to 9 pm for everyday of the week. The user will be able to choose the week to display from a datetimepicker control. The table holds each appointments date, time, length, cost, type, as well as an appt id for each appt and a user id to keep track of who the appt is for.

View 2 RepliesI am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

I am trying to populate a treeview with data from and xml document.
The loading of xml is no problem i have done that a million times over, the problem seems to be able to fill the treeview with content. My problem is this: I have a treeview with this in it:
-Race
|-HQ
|-TROOP
|-ETC...
now... the program loads all units from xml. so when it encounters for instance a unit with a "<class>" tag containing HQ, how do i make it put it in the HQ node? I cant make it put new nodes into existing ones, only into new ones....
