im trying to work with adding controls in runtime. Anyways ive added a ContextMenuStrip control in runtime and added a item called "Display". The ContextMenuStrip is also added to textbox's that are also added in runtime and when i right click a textbox i see the "Display" but i want it to do "msgbox(textbox.text)" when i click "Display".
[Code]...
is there a tutorial (i looked, couldn't find) on adding controls at runtime?

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.
I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?
I am very interested to see the answer as I would like to know the significant differences (if any) of generally using one more than the other. In a few days, I will be starting my Java programming class to familiarize myself with the language.I do know that Java uses objects.My question/discussion is not necessarily related to .NET (although in a way, it is); my question is more about what is a better practice and why.Is it more proper to declare buttons and such through runtime rather than designer? Is it just more work typing everything? Or does build and run much faster?

Updating a VB6 prog in VS2005 on Windows 7. The prog has an MDI + child forms and there are a number of content types, with varying numbers of controls being set up and positioned from setup files.On forms which are not child forms I can easily add controls at run time like this:
Dim lab As New Label
With lab
.Left = 0 : .Top = 0
.Width = 800 : .Height = 800
[code]....
This doesn't work on a child form, no label is visible. Can't see any obvious problem in quickwatch.

I am working with my project and I have difficulties in my program. This is the set-up: I put a textbox1 and a button1 in the form, textbox1 is for the property of the label text to be add
when I click the button1 I have another textbox, label and a button,I want the added button to remove the textbox, label and if possible the button itself, is there a way to delete a control by the added button?
I have a WinForms application that I need to dynamically add controls to at runtime. I searched for this and I was initially led to the TableLayoutPanel (TLP).
View 4 RepliesHow do you add an arbitrary number of controls to a form at run time? With indexed controls I could define the 'seed' control at design time and reference 'clones' of the 'seed' control at run time via the index. Now I must declare each additional instance of the control at run time then set each individual property that differs from the default for that control for each instance. Then I must add the newly declared control to the appropriate container controls collection. I'd like to do this in a loop but how can I get away from using a fixed control name in the declaration:
Dim controlname As New Control
I can't use a string that I can manipulate the contents of for controlname because it sees it as a double declaration. I can't use an array such as Control(index) for controlname. Dim Control(maxindex) As New Control doesn't work. Dim Control(maxindex) As Control works but any assignment based on this such as Control(indexvalue).Name = "ControlName" fails. It didn't address the issue of handling the declaration of new controls in a loop with some kind of variable name for the control.
Is it possible to add items to a contextmenustrip during runtime in a certain order?I have a program that is very flexible, it can do one instance to any number of instances of whatever, but I want the menu to be able to also display links to each instance.So like

I am writing a simple control translation function that reads an XML file containing control names and their localized text. Within the application, each time a form is loaded, it iterates through every control and tests to see if that control is defined in the XML file. If it is, it then sets the control text to whatever localized text is defined in the XML file.
There are some tests and additional requirements (i.e. nested loops) for TabControl and MenuStrip etc., but the control that is giving me the most trouble is the ContextMenuStrip.[code]...
I have made it so that as soon as the form opens it puts an icon in the tray and when you right click the icon it comes up with a contextmenustrip. in the form I have put a button and a textbox. when you click the button, it creates a new item in the contextmenustrip What I wanted to do was add a peice of code to this new item, is this possible?

I have an MDI application which uses fixed sized forms. I've started to change the forms to sizeable and anchored the controls so they move when the form is resized. If the child form has a menu this jumps onto the parent menu (as it always has done) but all the controls move up the form at runtime and leave a space at the bottom of the child. If I change the form in design mode to cut through the bottom controls i.e. so the form doesn't appear tall enough, it corrects itself at runtime. Is there another workaround as it looks misleading in the designer.
View 3 RepliesI have a custom control that the User can add to the form. They can add as many of these controls as they like.When they add a control, I am going to populate another custom control, a textbox, in another panel.I need to figure out how to associate that new control with the previous one.So, let's say the User creates 3, let's say "Boxes", three TextBoxes are created. When the User adds something to Box1, TextBox1 needs to be populated a specific string.I know how to create and add the control as needed, but I can't figure out how to associate the controls, if that make sense.In order to distinguish the Boxes, I've added a label to them that represents each iteration of the box. The numbers start at 1 and increase from there.I was thinking I could use that to associate the TextBoxes and am working on that now.

I'm trying to dynamically add a control to a form from an event that is raised from an asynchronious socket's thread.
In other words, when I get an OnDataArrival event is raised from the socket thread, I raise DataArrival event in my form. The form's DataArrival sub then tries to create and parent a control.
Whenever I try this, I get the following error: Controls created in one thread cannot be parented to a control in a different thread.I know a bit about delegates and invoking, and I think that's how to solve this problem, but I don't know where to declare the delegates and how to use them.
Ideally, I want a delegate/invoker to handle the DataArrival sub in the socket class so that everything that happens after that will be thread safe. Can this be done?
When I add a control to a TLP in design mode several new properties get added to the control, such as ColumnSpan, RowSpan, etc, which can then be set in the properties window. If I add a control to a TLP in code these properties don't seem to be available. how to set these properties in code if it's even possible?
View 2 RepliesI 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.
