I want to have a small control follow the selected tree node. However, I cannot find a way to get the location of the selected node (in relation to the tree control itselfI know I could use the mouse pointer location, but I wanted the control to 'snap' to near the selected node by using its exact visible location.

View 1 RepliesI have a tree view with a parent node. parent node will have 2 or more child nodes and the nodes data will come from a access database table. if I select any one of the child node with the mouse it will display the SUM of the child node's data in a label control below the tree view control. the access datable table might look like this [code]...

I'm currently working on a treeview but want to add custom nodes at design time, is this possible?Also the treeview is part of a control, so i have created a control designer and added a custom design time form to add my custom nodes, but can't seem to get the nodes into the treeview in design time, and serialize into the form automatically?All my custom tree node is is an extra integer at the minute, but more properties will be added later if I can get this working.

I have a treeview that is populated. The user will have some node selected in that treeview. A refresh function is called, and the program remembers the full path, so that after the treeview is cleared and repopulated, the same user selected node can be reselected for them automatically.
I have the full path of a tree node. If the full path is "nodea odeb odec" how can I automatically select that node using code?
I have a form called main with 10 number of text boxes.my second small form called popup & I want to appear right corner of selected text box. Ex - when I click 1st text box, I want to appear the popup next to the firs text box, then I click 2nd text box I want to move popup to 2nd text box.
so I used
New Point(10 + Me.Location.X + SerchTextBox.Width + SerchTextBox.Location.X, 20 + Me.Location.Y + SerchTextBox.Height + SerchTextBox.Location.Y)
the problem is I have large no of textboxes & difficult to changed each textbox name each place.
If I can get selected textbox coordinates X & Y its easy & compact. How can I find selected text box location.
I am writing a program in VB 2010. My computer is an E Machines dual processor Intel Celeron running at 1.8 gb/sec with 2 GB of RAM. I have a 1680 X 1050 display and the graphics driver in the computer is fully capable of utilizing this display. I am running Vista Home Edition.
The purpose of the program is to analyze a large number of infrared and visible light images from the geostationary satellites GOES East and West. Note: These images are TIFF and range in size from 400 KB to 70 MB. The pixels are either 8 bit or 10 bit depending on the image type.
The program allows the user to select a series of images from a file folder. These images are then displayed in a picturebox. A map covering the same area is also available to the user. The user may then move the cursor, via the mouse, to a selected location on either the map or in a picture. With a left click that location in terms of image coordinates is used to compute the geographic coordinates of the selected location. These coordinates are then displayed for verification purposes. So far, all of this works properly.
The next thing I need to do is to determine the brightness value of selected pixels in the displayed image. Because brightness is related to temperature this permits a detailed examination of cloud temperature and density in each image. By making this measurement at several different wavelengths (provided by images taken at different wavelengths) the program will then compute the atmospheric extinction factor at each selected wavelength and from that derive the atmospheric transparency function.
Here is where I have run into problems. I cannot find a way to extract the pixel value from the selected X, Y values input either by cursor position or by direct entry. I have tried the various approaches described in the documentation but I either get errors or a pixel value that is unrelated to the image. The following is a section of code that I am currently trying.

I was using this old method of creating a bunch of rectangles when I need to get the location of a certain point within a grid so I could draw images on the grid. The thing is, I don't want to use rectangles, I want to be able to just round the location as if I were using rectangles. I need it to be able to round the point (66,70) to (50,50) so if you can imagine a grid and the mouse position being within that square in the grid, I need to get the location of the upper left corner of that square.
View 5 RepliesI have a combobox that drops up instead of down. I'm setting the selected item to the one on top of the list. I'd like to move my mouse pointer to point to it, so that the user that wants to click on that item doesn't have to move his mouse. I found how to move the pointer, it is with this command:
Windows.Forms.Cursor.Position = New System.Drawing.Point(x,y)
but I need to know how to get the location of the selected item in the combobox.
I am trying to copy an entire folder and all of its contents that is in the same location as my program that is running to a user selected location. I started off by using a SaveFileDialog, but now I am working with a FolderBrowserDialog. Here is some code:

I have some code that allows me to drag a treenode into a listbox and then drag it back into the treeview as needed. When I drag a node out of the treeview, the node is removed from the treeview. When I drag it back, I need the node to be inserted into the same parent node/position it came from. I think I can save the node's FullPath property before removing it from the tree, then decipher it again when I re-add it but am looking for a cleaner way
