View 3 RepliesI have a couple of user controls, which I show in my main form.
So let's say here's what i want:
Sub Show_Control1()
UserControl1.Show
'CODE TO HIDE EVERY OTHER DISPLAYED USER CONTROL ON THE MAIN FORM
End sub
Right now I have to hide them one by one with hide, because I don't know what's the current displayed form.
I have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...
My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.
I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.
Dim pccard As New PC_Card
Dim x As Integer

I am creating an application for a company and this CD will be distributed to hundreds of people. Many users will have different computer screen size and different screen settings such as their resolution set to 1024 x 728 and their monitor size 17" inches.
I noticed when I loaded the application on a different computer with different settings the application was to big for the screen and did not work. I notice that lot of other programs from microsoft resize their controls and text but never knew how they did it. How can I resize the form and control according to the user's setting.
I have a picturebox with controls on it. I wanna save it as a pic with controls. I have seen a getimageofcontrol() func. on vbforums earlier that does exactly this. But I am not able to find it now...
View 3 RepliesThere 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.

How to capture when a user switched application windows. Basically what i want to do is for example is when EVER a user works inside Microsoft Word i want the CAP lock to be turned on. When they leave Microsoft word's app window and select a new app the CAPS button would turn off. Then when they return back to Word caps turns back on. I have code I found in another post on how to turn CAPS on, now i just don't now how to automatically capture application switches running all the time. My idea is to create a small app that can be minimized to the system tray then let it run and capture all thE app changes.

View 7 RepliesI have several UserControls in an ASP:Repeater. They are 'Add to basket' User Controls with a text input for quantity and a button to add the item to the basket.
My problem is the value is being reset to 1 whenever I enter a value into the quantity text box. I think this is happening because the containing page reinitialised the repeater (which holds the UserControls) and the quantity is one again before the UserControl's click event is fired.

Currently I have the start-key for my vb.net application hardcoded like this:
GetAsyncKeyState(Keys.F2)
Where vb.net sais "F2 As System.Windows.Forms.Keys = 113" on mouse-over.But I want my users to be able to pick their own Key. If I make a drop-down box (combobox) and pre-define some choices in there (Like ESC or F3), all those choices are strings. How can I convert those strings to a System.Windows.Forms.Keys integer? Also, I'd like it to also be possible to "capture" a single keypress. So they'd click the "capture" button, and the next key they hit will be saved as the start/stop button. But I wouldn't even know where to begin looking for that one.

View 5 RepliesI have a custom control with an event handler when you click on it. Everything works and the event get fired right.
AddHandler (cu.MouseLeftButtonDown), AddressOf Me.DoSomething
When the control resizes to show some extra information it expands. It also collapses when the user preses a button. This works alright. But now when I click where the expanded area used to be, it still fires mouse leftbuttondown on that control. I have tried to set IsHitTestVisible to false on the expanded element but it diden't work. Here's some xaml...
<UserControl x:Class="MyCustomControl">
<StackPanel>
<Grid>

I cant use another element around my customcontrol since I also use this MouseLeftButtonDown on all different kind of controls.
I can't figure out how the boundaries on the cu.MouseLeftButtonDown event work to fix this.
I have some custom user controls in my .net winforms program that do not display correctly when the user has selected larger text size. This setting:
My controls look like this:
Instead of like this:
The bill to area and ship to area are both custom controls. I don't know if this is contributing to the problem but I do have code in each to scale the phone/fax areas to stretch nicely, like this code from the bill to control,
Private Sub panFaxPhone_Resize(sender As Object, e As System.EventArgs) Handles panFaxPhone.Resize
panFax.Width = (panFaxPhone.Width / 2) - 1
panPhone.Width = (panFaxPhone.Width / 2) - 1
panFax.Left = panFaxPhone.Width - panFax.Width
End Sub
How can I get my controls to size correctly while still respecting the users choice for larger text (I don't want to just set the AutoScaleMode to None)? After playing with this for a long time it seems to be a problem with anchors in the child controls. See this below image, the inner black box is the control with its border turned on, the text boxes (like name) are anchored left and right and should stretch to fill the control, but don't.

The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
