C# - Get ALL Child Controls Of A WinForm Of A Specific Type (Button/Textbox)?
Aug 5, 2010I need to get all controls on a form that are of type x, I'm pretty sure I saw that code once in the past that used something like this:
dim ctrls() as Control
ctrls = Me.Controls(GetType(TextBox))
I know I can iterate over all controls getting children using a recursive function, but wondering if there is something more easier or straightforward, maybe:
Dim Ctrls = From ctrl In Me.Controls Where ctrl.GetType Is Textbox
VS 2008 Which Controls To Use For Db View, Asp Alternative
Aug 8, 2009I have a vb application ive been working on and its pretty much complete. I posted in the asp section but we couldn't get it figured out there so im reverting back to vb so looking for some help.I have a vb.net app I created and I have an internet browser embedded in it calling an asp page. the asp page is just a simple file that searches an access database. I used the asp page because I wanted to display the results with graphics and tables so I used html for that.Everything technically works except I am running it on a local intranet and the asp file is located on a server that is REALLY slow so it is taking 20-30 seconds to get my results. so, my question is, Are there any other options or ways I can do the search within the vb app itself so everything stays local and I don't have any speed issues. I can't install IIS on the local computer because the IT department is strict unfortunately.I don't HAVE to use "html" but I would like it to look nice with graphics and html was the only way I knew how to do that.

View 1 Replies.net - Cross Thread Operation On WinForm Controls?
Sep 8, 2010In main thread I create panel(s) (based on some configuration), and then in the next step based on the file type (like video, ppt, image...) I create appropriate controls (dynamically) to show on the forms.
The creation of the control will be done in separate threads (for each file). After creating the control, it throws an error when I try to add that control to the panel (which was created in the main thread), something like cross thread violation, control was accessed from one thread other that it was created.
Can some one please help me in this regard? In this scenario, everything - creating the panels and controls - will be dynamic. Nothing will be static.I tried some of the articles found here on StackOverflow (like, control.BeginInvoke() .. etc), but wasn't able to solve my problem.
Multiple Controls On Winform Mutliple Threads?
Jul 3, 2010I've created a news ticker control, which reads from RSS feeds and scrolls the text Horizontally. The plan is to have 3 of these on my Windows form, which will each display their own information.
The control is created as a label, which is populated with the text, and then scrolls right to left using a timer, once the label gets to the end of the text, and disappears of the left side, the rss is re-read, and then the cycle resumes. The problem is that with multiple copies of this controls on my form, once one gets to the end of it's run, all three freeze while the rss is reread, rather than just the control that needs to do it.
Is there a way to run each of these controls independently (threading?)? Or is there a glitch in my code causing this? (below - some elements not included, but it should be fairly obvious what is happening!)

Validating Controls Within (WinForm) After Data Populated
Mar 18, 2011I have a form with a datarepeater that contains various controls (i.e. datetimepickers, text boxes, combobox) that are populated via a binding source. I also have other controls on the form that are not part of the data repeater. I would like to force validating all controls after the data is populated. I have successfully forced validating the non-datarepeater controls using Me.ValidateChildren() at the end of my load event. However, it does not fire the validating events for the controls within the data repeater. I have unsuccessfully tried many different attempts to set and move focus within the datarepeater controls trying to get the validating events kicked off. I am not sure where would be the best place (e.g. in drawItem? in ItemCloned?) to place the code and what it should be exactly.
Here was my latest attempt:
Private Sub DataRepeater1_DrawItem(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) _
Handles DataRepeater1.DrawItem
For i = 0 To e.DataRepeaterItem.Controls.Count - 1
e.DataRepeaterItem.Controls.Item(i).Focus()
e.DataRepeaterItem.Controls.Item(0).Focus()
Next
I successfully handled the validating events in the data repeater caused by user input errors. However, I have the unusual situation that the data coming into my form is already bad for some of the controls. The purpose of the form is to validate the data coming in to it and from user-input. I am newbie with vb.net.

Alternative Code To Add Command Button To Acheive The Functionality From A DLL?
Sep 22, 2009An excel addin was used for a report data from database employing flat files. This addin uses activeX controls to acheive the above functionality. However it was later identified that when associated with digital signature to make it run under high security settings the whole addin crashed.
However the Point of concern now is'A new dll has been developed that encapsulates all the functions of the existing addin.' The addin was registered and as it was used, it created multiple instances of excel objects vigorously. However it was identified that this was due to a portion of the code that caused a command bar to the inserted as shown below Set cbar = CommandBars.Name("My data extracts")
Can an alternative code snippet be given which would insert a CommandBar?
Controls Keep Moving Down On A Winform Panel After Running (in Debug Mode)?
Aug 8, 2011I have a winform with a main panel that is anchored top, left; dock: fill, and set to a specific size to contain another panel of content that we want to scroll through. The other panel along with a few other controls are on the main panel. Now, for some reason, after running the application the controls will be shifted down (never horizontally) some random amount. Now, the "random amount" may in fact be the last position of the scroll bar or something, but either way, it is unintended functionality. I have resorted to automatically resetting the locations of these controls on the main form in the constructor?

Making A Winform Button Look Pressed From Code Behind?
Nov 3, 2009I've got a basic VB.net 2.0 application together in VisualStudio 2005. Within a form, I've tied [enter] in several text boxes to a button. What I'd like to do is "press" the button from getField_KeyDown() to give the user a visual indication of what's happening.With the code below, the button click work is done but the button's look doesn't change and the user is left without feedback.
Private Sub getField_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles txtGetKey.KeyDown
If e.KeyCode = Keys.Enter Then
e.Handled = True
Call btnGet.PerformClick()
End If
End Sub
How can I make the button looked pressed while the btnGet.PerformClick() work is being done?
Manage A Large Number Of Similar Controls In A User Interface (such As Button Or TextBox Controls)
Aug 23, 2011There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

During the debug process, I click log on button there's a line of code where I want to step through which it's calling a diffrent project in the same solution to validate the username and password. But it doesn't allow me to step into that project to validate the data. It just goes right through it and the username and password pass validation right after that line of code.

TableLayoutPanel/Button Controls Being Very Odd?
Jul 17, 2009I have a class here that is misbehaving, and I can't understand why.Basically, when resizing to make this Form smaller, the buttons begin to extend outside of the TableLayoutPanel that contains them. This is not ideal.This is not an issue about resizing, my project does not allow resizing the main form, the problem occurs on my form before any resizing takes place; I simply demonstrate that the problem gets worse when resizing here as additional information.

Calculating The Sum Amounts Of Multiple Button Controls?
Apr 11, 2009I've been working on a project for a class for the last few days. Here is my current issue, I have created a form where I have multiple buttons representing different t-shirt with different prices. So hypothetically, if the end user were to click on the button that is assigned to red size small there would be an extra $2.00 (on top of the $5 fee of any other t-shirt), I know how to code for the calculation of one item, but I'm not certain how to add say a small red shirt, and a large pink shirt, and have the two items calculate correctly.
