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. How are those controls created? I imagine it involves using the existing controls in Visual Studio as a starting point, and altering them to suit your design?

Sep 11, 2011How to properly create custom controls containing populated lists?For example: I need a combobox control which contains a list of products, then I would reuse this control in other project.
[Code]...
and it works but when I run the project each item is duplicated - this is because list is populated twice. First when user add a control to form, second by designer when project is started.I already found a solution to prevent adding items in edit mode, but this is not what I need. I would like to have them existing in edit mode so they could be edited at this point.

View 6 Replies.net - Create Custom DataTable Which Is Bindable To WinForms Controls?
Aug 25, 2011Our shop primarily use "ADO objects" (I'm referring to DataSet, DataTable, and DataRow) for marshaling around data and manipulating it on forms and in grids. We are experimenting with creating shop-flavored counterparts to the native ADO objects so that we can impose our in-house standards on top of them. Implementing this is straightforward with one exception: I want our objects to be bindable to controls.
I'm aware of IList, IBindingList, BindingSource, etc. and have looked at and experimented with these, but I am falling short when it comes to making a class with no hard property names bindable. The native ADO objects are not strongly typed by default. You have column values that you access via the Item property (e.g. row("Age") or row.Item("Age")). The binding examples I've found online deal with strong-typed objects (e.g. row.Age). Essentially, we want to create custom ADO objects (not inherited from the native ones) that still retain their ability to bind to controls. In a grid I would expect to see columns Name, Age and Occupation from a row where these properties are exposed via row("Name"), row("Age") and row("Occupation"). This must be doable as this is exactly what the native DataTable and DataRow provide.
Controls On Third Party Apps
Jan 1, 2010Im trying to detect when numbers change in a 3rd party app and then capture them for crunching.

Ive got window handles ok, just cant read the control data.

Mar 12, 2011We recently aquired a first generation ipad and after playing around with it, it occurred to me that many elements of my current vb project could find an audience in this technology.

Since this would require an unacceptable investment with my current finances, I am wondering if it is possible to create these apps using visual studio with vb.net, c#, etc.

View 6 RepliesCreate Custom Database In Windows Application - Double Click Custom Database File?
Jul 21, 2006With VB.net, I'm coding a simple application to get more used to the new .Net format.
I'd like to save all the information to a 'new' database file. how to create a database on the fly, once that is done i'll be able to connect to it no problem, but actually creating the file is proving difficult to work/find out.
Also, with vb.net and the newly created custom file, how can it be made to automatically open that information with the program?
Is there a method in installation to associate the file type with the new program? How can i check when the program loads if a database file has been 'double-clicked' (rather than just running from the .exe of the program) and proceed to load the data?
EDIT1 - Extra InfoThe windows application has many different fields and content etc, then i need to save that to a file that could later be loaded by 'double clicking'. I assumed the easiest way would be to create a mini-database for each unique file

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?
Resizing 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 3 RepliesMaking A Dictionary In .Net - Create "apps" For Wikipedia, Wiktion?
Jun 13, 2011Basically, what I've done is given the user four tabs to choose from. The main one is the dictionary which I've compiled, and the other three tabs link to online encyclopedias and dictionaries. However, what I want to do is make an app for each of these, because of the fact that the screen space I am giving the user is limited (499px x 254px), and I also believe that it will look more professional.
What I'm thinking of doing is putting the logo towards the top, and then:For Wikipedia, putting the title and picture at the top and breaking the article into show/hide sections like the mobile version
For Wiktionary, putting the title at the top, and breaking it down into show/hide sections when applicable
For Dictionary.com. putting the title at the top and showing the definitions (with linked pronunciations) underneath
Of course, I'll need it to automatically redirect itself to the webpage I need it to go to, because I don't want to type another 300,000 lines of code just to go to a website.

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?
