Resizing Items In Custom Panel
Sep 3, 2011
I've been programming a Fisheye-panel that holds image and make it behave like the icondock in Mac Os X. But now i have a problem. When i add to many item, i want them to shirk, to make room for more, or grow when i remove icons. This is the behavior i get: When i want them to grow, they don't grow at all. When i want them to shrink, they shrink, but leaves lots of empty space (like replacing a photo from a frame with a smaller photo. The image shrink, but not the frame)

way to stop resizing a panel here's what i got:
I have a CaptionPanel containing a DataGrid. The user is not allowed to resize the panel beyond specified values (min/max height and width).
In the resize funtion (handling the resize event), i'm putting conditions on the height and width:
Private Sub myPanel_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles myPanel.Resize
if myPanel.height>maxHeight

I'm not going to post my code for my transparentlistbox class, but here is a link to it.It's been working fine as is, until early this morning when I tried to set a different size.[URl]..For the longest time I placed a normal listbox control on a form and resized that, setting a new public variable of transparentlistbox to the same size/location as the original listbox, setting the visibility of the original to false, and adding the transparentlistbox to the form (me.controls.add).It looked like this:
[Code]...
Now, since I've moved some buttons around on my main form, I resized the original listbox control to be wider (same height though). When I tested, the transparentlistbox (code didn't change still set to original listbox size/location), the size was that of what I had the original listbox set to, before resizing?
So, I commented out all of the custom drawing/paint events/etc I could find for the transparentlistbox and tested, still stuck to the original size. I stepped line by line debugging and verified that transparentlistbox1.size=listbox1.size indeed matched the new resized size (but didn't actually resize)?
Last I did was comment out the transparentlistbox.visible and put back the listbox1.visible and listbox1 does indeed show with the new resized size? I'm not quite sure what to test next?

I have custom collapsible panel control. I put it into a FlowLayoutPanel. he FlowLayoutPanel is docked within my form. The Panel Anchor property is set to Left/Top. The purpose of the anchor is so that if I want to put multiple panels in the FlowLAyout Panel, they will all stay snuggly together when they are expanding and collapsing. The panels work fine.

I have created a custom Panel Control as follows:
Namespace CustomPanelControl
Public Class CustomPanel
Inherits Panel
Public Sub New()
MyBase.New()
[Code] .....
Now I need to use it and make it fade in and out. This is a panel containing typical play, stop, FF, REW controls over a media player. Just like Windows Player or VLC, I want the panel containing the controls to fade out on mouse leave and fade in on mouse enter.

I have a program that is sorta like the iphone shop.
When you load a selection, I want it to read from a website, about the information of what to add (Finished)
So each "Item" consists of a Picture, a number, a set of text, and a button.[url]...
So far, I have made a parser, which reads this, and determines the size of the button, the name, but how do I create a button, with the specifications, and add them under the parent of the panel?

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]

I'm trying to create a simple transparent PANEL control. I want to create a custom control based on the existing Panel Control with a property added called "transparent" which can be set to true or false. If it's set to true it's transparent(not invisible). So if I place it over some controls in a form say a button or text box... they are visible but disabled.

I need to have a custom background on a panel that can be resized with the form and want to know how I should go about designing it. Maybe have three images the left side, right side and the middle is just replicated? The thing is I would like for it to have a border and there will be buttons attached to the top edge so simply stretching a static picture may make the buttons not line up properly.

I have inherited the standard panel control to create a panel having custom border color. The problem is, while the panel is on a form and any other form is moved across it, it paints hapazard lines of the same color as the panel custom border color, all throughout background of the panel. I tried to Refresh or Invalidate the panel in its paint event but of no avail. The same is happening while designing in the design editor too. See attached image. Why is this happening and how to get rid of it? My code follows:

I created a custom control and I'm trying to insert it into a panel, but also center it.The control itself is larger than the panel, so I've set the AutoScroll property of the panel to True. I think that might be affecting it. Perhaps I should just offset the Y axis a bit.But, either way, this is what I'm trying:
VB .NET
'Create the control
Dim AutomationReport As New AutomationReportControl
[code]....
It works just fine with the X axis, but the control is out of bounds vertically. About 1-2 inches of the top is cut off.

I am fooling around with VB for a while now and it is not the first time I created custom controls to use in an application. The situation: I have a database application (FormView / not GridView). The form is designed the following way: At the left I have a Panel1 with TextBoxes and other controls to view / edit dataset records. At the right I have a Panel2 which contains on default a custom control (a number of PictureBoxes mainly) to view / add / delete pictures associated with the currently viewed data record.
On a ButtonClick at a special button on the ToolStrip, I would like to replace that custom control in Panel2 with another custom control (which contains a search with different search possibilities), so, I basically throw out the PictureControl and load a SearchControl instead. This is the first time where I actually designed the custom controls within the actual project. In past, I always developed the custom controls seperately in a new project and later imported the dll. However, my first attempt just does not work and I don't even know where I should start troubleshooting since I don't get any errors.

I created a custom control. I put it on a form with Dock = Top. I place a standard Windows Panel below it and set it's Dock = Fill. I would expect the top of the Panel to bump up against the bottom of the custom control, but instead, it goes underneath it and jumps all the way to the top of the form. This behavior does not seem to exist if I place two Panels on the form and set one to top and the other to fill. The second one bumps up against the bottom of the first one, as I would expect. But my custom control (from UserControl) does not seem to work this way. Do I have to set something special on my control?

I'm trying to create a custom control that contains a List(Of Panel). I quickly ran into an error about the base class Panel being nonserializable. So I created my own class that inherits from Panel and implemented the ISerializable interface. At the surface, everything appears to work, at least everything at design time. I don't know what would happen if I tried to run the application. Anyway, the errors occur when I try to open a file that contains my custom control. For example, I create a new Windows Form and add my custom control to it. I save the Form and close it.
Then I try to open the form and get the following error: Object of type 'MyTestApplication.SerializablePanel[]' cannot be converted to type 'MyTestApplication.SerializablePanel[]'.
I don't know what I'm doing wrong? I've opened the XML file to see what it's actually writing, and read the header notes about using binary base64 serialization. I think that's what I'm using, but I'm not sure.
Below is the code for the class SerializablePanel:
Imports System.Runtime.Serialization
Imports System.ComponentModel
<Serializable()> _

I'm having trouble with my panels. I taught myself VB (and the other languages I know) so I don't know all the terminology, so bear with me. But I'm making an application, and in this application I have a set of radio buttons, and because I only wanted one to be checked at a time, I put them in a panel. The problem is, I want to add more stuff to the application (form?) and anytime I add something that is in the area of a Panel, it becomes part of that Panel.
This is all fine and good when you are trying to drag and drop something right into the panel, it makes it really easy. But when I'm trying to drag and drop something else in that area where the panel just happens to be, I don't want it to be in that panel. So how can I make it so the panel stops parenting my other items on the page? I hope that makes since.

I created a simple custom controlled Panel for double buffering. When I use the control in my toolbox it works just fine, but when I attempt to add controls inside the panel those controls aren't staying when I move the panel around. My custom panel isn't acting as the controls' parent. I verified this by looking in the designer code.
I tested a standard panel on the same form and it works perfectly normal - as I drag the parent Panel the interior controls move along with it. It is only my custom Panel which doesn't seem to detect when another control is placed within it.
Here is my constructor
Public Class DBPanel
Inherits System.Windows.Forms.PictureBox
Public Sub New()

this is what i have now:

For Each cCon In parent.Controls

I have been trying to understand how to make thumbnails that I create from a directory, and place in a flow layout panel, selectable. That is, when someone klicks one of the thumbnails that thumbnail should be selected and, either automatically or by the click of a button, a new window (picture viewer) opens and shows the original picture. This is probably very easy to implement, but I am at a loss for the moment.I've tried to find an answer to this by searching the forums, but nothing good has been found so far.
[Code]...
The above code works perfectly and creates thumbnails from the directory c: emp and whatever subdirectory the user writes in the textbox (textbox2). No problem here, it is how to proceed to the next level that has got me stumped. As stated I want the user to be able to select one of the thumnails to get a better look at it in another window. So in selecting it, the procedure should get the path to the original image, and the rest is magic.

I have a project with 150 (i counted) Items in the "MainProject Components" area of the toolbox panel.These 150 classes are mostly database related objects like table adapters, and datasets that i hardly ever use. I also have about 10 custom classes that i use often.When i need to access the toolbox, I have two issues that i would like to resolve.
1.How do i organize the toolbox to separate my custom controls from the table adapters and datasets?
a.I have created a custom tab within the toolbox.
b.I have dragged and dropped my controls into this new area.
c.All is well until I exit my program and re-open it. Voila they're all back in the MainProject Components" tab.
2.How do I force the IDE to instantiate the toolbox panel as completely collapsed?

I have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.

how to create a panel full of items (textboxes, buttons, labels, ...) and save it as a class with all it's properties so I can create it and place as object on other panel. My goal is to create an application with menu on the side and change workspace (the part on the rest of the form) between 3 or more possible different "workspaces" (made by the classes).
