I need some advice: I need to create an app involving draging images to a treeview. What should happen is once the image is dragged to the node it must take an instance of a property. For example
[Code]....
I'm designing a new application, but have two big problems.I wanna put an image in my form, and have the possibility to drag them.For example, I put an image with 100*100 but my imageviewe ronly have 50*50 So, I wanna drag the image around the imageviewer.
How can I do this?The other problem is:In the image I wanna design some squares, with the possibility to drag them to.Drag the squares it's working fine.But, the problem is, when drag the image, I wanna the squares "follow" the imagem and keep thei position in the image.If it was confuse, I try upload an explanation image.
I want to loop through all objects that are loaded in my project ofType x and change a property in each of them... Is there any way to do this?

View 3 RepliesI am trying to create a property for objects, though I am not sure if that is what it is called. For example, PictureBox.Image instead of Image I want to use my own property.

I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?

I need to iterate a collection of objects. Based on a property value of the object, I need to group objects together. I also need a total count of each discrete property value. I do not know how many groups there will be and there could be 1 to n objects in each group.How do I do this? Are there algortihms that could help me out with this? Psuedocode or references are fine.
View 2 RepliesI have a form with a series of basic objects,, a list box a few buttons, a few text boxes and a few labels..
Anchor property works just fine on all of them except one text box and one label. The property is clearly SET on both objects and I can't, for the love of me, figure out what is making these two act "disobediently".

But i get error in For Loop: Object reference not set to an instance of an object at the first line of for loop.
The app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

I have designed a small component I need to derive. The problem is one property from base class doesn't make sense in derived class, but won't hurts too (just it's ugly in property editor)
Now there is a solution to make that property non-derivable or hidden in derived objects?
I have a custom class (Class1) with a bunch of properties. One of the properties of this class is another custom class (Class2) with its own properties.I have a property grid with the selected object set to Class 1. I can see Class 2 as a property, but i would like to expand Class 2 to show its properties in the same property grid.
Im basically trying to do the exact same thing as the Font Class on a form. If you look at the properties of a form in the designer, you can see the font property. You can then expand that to show the properties of the font class.
I know how to add images to Form Controls by using the Property Window.However I am trying to use Icons on the form to indicate error.Example: If this condition is true, display this image, else display that image.
I could do this using multiple labels on top of each other but wondering if there is an easier way.
I have an imagelist control in a usercontrol I made. I would like to create a property for this usercontrol, to select multiple images (in an 'openfiledialog'), and adding them to the imagelist inside the usercontrol. So, what's the type of this property?
Public Property thelistofimages as [?]
It should be an array of images I guess. And then in the 'set' of the property it would add all the images to the imagelist.
I need this for my program. There is "add images" button where you can load multiple images and those images should be show on listview after loading.I have been trying to make this but could not get it work.

View 9 RepliesI have a listbox with several list items added. I want that as user click on an item, I should be able to show its property. This should change for different items. For example (hypothetical) : Listbox has numbers 1 - 10. Now when I select 1 I should be able to set property - Name, Lastname, Colour, Age.
When I select 2 I should be able to set - Age, Hair Colour (clr shows), Weight, Date. When I select 3 then - City (combo box drop down), Country, Age only. This way value changes for diff items. One way is to put them in property grid and show them. Though this looks nice but adding/removing items in that is not easy. You need to have a class that refer that to prop grid. Do I have to code for each classes for all values in listbox or is there an easier way to manage items in property grid. If you think prop grid is not the right tool for such an activity then can you suggest something else.
make objects from the ToolBox using code instead of changing existing objects invisible then visible later?

I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)
[Code]...
I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!
long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.
The idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesI was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
