View 2 RepliesDraw A Custom Icon Into A Tooltip?
Apr 4, 2010Not a single site anywhere, and I have even tried the MSDN, that details in any specific language how to draw a custom icon into a tooltip.
I have tried using every format of image I can produce, including (but not limited to) ICO, PNG, GIF, BMP, JPG etc... But every time, the app debugger clouts me round the head in defiance.. Windows Vista CAN do it.. and as in the image above.. StarDock figured it out..
I know your policy is to have the askee produce their code first, but the thing for me is
Also, I wonder if it would not be possible to take the code that does do the whole shabang, and compile it into a DLL or something that I can just embed for future projects - again this can be uploaded for others to refer to.

View 2 RepliesDraw Text On Custom Control?
Dec 23, 2009I have made a custom control and the only change to the interface is that its a different color. Whenever the user moves their mouse over the control some white text fades in in the middle of the user control. Then after a few seconds the text fades out. The text is actually the location of the cursor but I have that figured out.

Draw Custom Buttons On Windows Vista / 7 Aero Titlebar
Nov 7, 2010I found this question on StackOverflow. Basically, the user wanted to draw custom buttons on the titlebar. I tried the code and realised it works in vista/7 only when Aero is disabled. My question is, is there any way to draw custom buttons on the titlebar while aero is enabled? Any way of reading information from the current theme so I can style my buttons to match the already existing ones.
Here is a screenshot from my computer demonstrating the above concept. I got the additional titlebar buttons after installing DisplayFusion. And I know DisplayFusion is a .NET program because it opens in .NET Reflector. The down side is that the program is obfuscated. Not like I wanted to decompile the program or anything; I just want to add a button to my titlebar to do something else (like minimise to the system tray for instance).
Below is the screenshot, proving the program is a .NET app.

View 10 RepliesCustom ToolStripItems Painting - Draw Graphics Without Calling The Refresh Method?
Nov 11, 2011I have created a custom ToolStripProgressBar. It is basically a class inherited from ToolStripStatusLabel, and i paint the 'progress' bar myself (just a simple rectangle). I have tried creating a custom ToolStripProgressBar using different methods including inheriting from both ProgressBar, ToolStripProgressBar and ToolStripControlHost. I always ran into difficulties doing in this way. Inheriting from ToolStripStatusLabel works well, but with one issue...
In order to have the progress bar update in the statusbar, i have to call StatusStrip.Refresh. Trouble is, adds a huge overhead to the drawing of the progress bar graphics. Simply calling the invalidate method of my ToolStripStatusLabel does not seem to render anything to the screen. how to have my graphics draw without calling the refresh method?

View 6 Replies.NET For Each Exception On Custom Controls?
Dec 9, 2011in VB.NET i have 2 custom controls, one is a TextBox and second one is a ComboBox.These have custom values like Bool _IsHidden and are added on runtime to a form.Now, at some point in the code I want to check if the _IsHidden is set to True or False and display that information. Since the user can edit this values when creating the control these are not set on creation.
So what I tried is:(all of this is on MDI Forms)
For Each frm as CustomForm in Main.MdiChildren If frm.MyName = calledBy Then 'this part is just to know which form called the form to create the object For Each cntrl as CustomTextBox in frm.Controls'DO Something
Next End if Next
Now.. if the first control is a custom ComboBox it thorws an error since it sees that it does not match the custom TextBox control..how do i get around this? By my understanding it should just go through all of the controls on the said form and just check those who match CustomTextBox control ?
Arguments For Custom Controls?
Nov 24, 2011I've created custom buttons in a .dll and they work fine, so I thought I'd have a go at creating my own sort of listbox to replace the standard one in my applications. It's basically a panel with a few labels and a button (eliminating the need to select an item in standard listbox then click a seperate button). I want to add these panels to a panel on a form, at run-time, based on rows in a db.
If I try adding any arguments in the New() section of the class file it won't let me use the panel in my toolbox. Is there a way to pass arguments to custom controls, I need a new custom panel for each row in a db so need to pass an id to it to specify records; or even load the records in my application and create a new panel for each record, using info passed to it to fill in the labels on it. Or can I create the panel at run-time and refer to labels within the custom controls, setting their .text properties that way?
How To Create Custom UI / Controls
Mar 19, 2011I would like to expand my knowledge of VB.NET and was looking at creating custom user interfaces or custom controls. The type of things I am thinking of is: [URL]s.

View 2 RepliesResizing And Custom Controls?
Dec 10, 2010I'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?

View 2 RepliesCustom Controls Disposing & Memory?
Apr 14, 2010I've been working on a few large custom controls, and I noticed that when I use them, my memory starts ballooning. If I add a control at runtime, it increases the memory, but when I remove the control, it decreases less than it increased. However, it would stop balooning at some higher value. So if go back in forth between pages (which adds and removes the control), the memory would look something like this:
1,000K|5,000K|4,000K|9,000K|8,000K... 20,000K|25,000K|21,000K|25,000K|21,000K|25,000K... etc I know it takes a while for the GC to run, but the memory would stay consistantly high for long periods of time.
I tried writing a Closing routine, where when I called it, the control looped trhough its children and disposed all the internal controls, which seemed to help a little, but the memory after running the control and disposing was still much higher than before running the control. I also use custom event addhandlers. Should I remove all these as well. It would be nice if I received a little guidance on this.

View 2 RepliesHandling Focus With Custom Controls?
Nov 3, 2011I have a custom control I'm creating. When I click on it, it draws a dotted border and puts some nubs on it for resizing. This all works perfectly. Now I want it so when I click off of it, it deselects. I already have a variable to set up if it's selected or not and subs to draw/clear it. I just have to be able to detect when something else is selected or it gets clicked off of.
What I've Tried
My first and best solution to this was to use the LostFocus event, but, by custom control apparently won't let it fire. After some research, as far as I know, custom controls don't have Focus events because they are custom and could be changed (basically, you have to implement the focus events yourself).
My Question
Does anybody have a solution to either implement the focus events or a way to handle off clicking for custom controls?

What Is The Best Reference Material On WPF Custom Controls
Aug 24, 2009I currently do all development work in VB.NET 2008, winforms; but within 18 months will be switching to WPF (for better or worse). I have had great success using Matthew MacDonald's "Pro NET 2.0 Windows Forms and Custom Controls in VB 2005" book. This is an excellent reference focused entirely on the development of custom controls in windows forms. ( Many of the controls that I use have to have a very specific UI look and feel, so they end up being custom.
I'm looking for pretty much the exact same thing, except focused on WPF. MacDonald has a new book coming out on WPF in general ,but not on custom controls. Books are my preferred reference material, but any good web references.
