I want to create a Panel dynamically on the form when a button is clicked. Also labels with given TEXT are also to be created when create label button is clicked. then we should be able to print the form contents as it appears but without any buttons. We should be able to resize the panel to adjust the page size.
View 1 RepliesI am having some problems adding controls at runtime, or I guess I should say accessing the controls after adding them.The application starts off with a tab control named "tabIncidents" and one tab for an incident information. The user can click on a button to add a client. When the button is pressed a second tab is added to "tabIncidents" named "Clients." On the newly created "Clients" tab another tabcontrol is added named "tabClients" and we create a tab named "Client". Multiple "Client" tabs can be created on this tabcontrol. Each "Client" tab gets a usercontrol added named "clientInformation" which has name and address textboxes.
So basically it is ...
TabIncidents.tabFirstTab (already exists)
TabIncidents.Clients (new tab added at runtime if user clicks a button)
TabIncidents.Clients.tabClients (new tabcontrol on the new tab)

I know how to create a control at runtime e.g.[code]Can anyone tell me how to create multiple instances using a for-next loop? e.g.[code]The part I can't work out is how to give each new button a new name... like button1, button2 etc

I need the picture to have a tag value so i can use them later.
I have created a usercontrol that contains two rectangle shapes to create a unique button effect and a rounded-corner rectangle shape serving as a border to provide a look similar to a group box. It also contains two labels, one for use with a Text property of the control and the other to indicate the status of expansion of the control. The control is designed to collapse itself when the "button" is clicked leaving only the "button" visible. Clicking it again toggles this affect. I've dubbed it an ExpansionBar. It is also designed to be a container control so that I can add controls to it and allow these to disappear when the bottom portion collapses. The problem is that the controls contained in this usercontrol cannot be accessed during runtime. In other words, I can add a checkbox to it and it will disappear correctly when the control collapses, but I can't select the checkbox to check it... same thing with any other controls, you can see, but can't touch. I'm a novice developer, so I'm sure I'm missing something obvious.

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

This doesn't work on a child form, no label is visible. Can't see any obvious problem in quickwatch.

Supposedly I have a datatable containing 2 columns (controlname as string, containing the name of the control and controltype as string containing the type of the control), for example ("label1", "Label") On runtime i want to loop over the datatable and create the controls from that datatable and add them to the form accordingly. but the problem that i don't know how to convert the control name to a control type, meaning that i want to convert label1 to a type of control Label, inorder for me to set its properties on runtime. so how can i do this and is there a way to convert the string to control according to it controltype.

View 1 RepliesI am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.
View 1 RepliesAt design time in the IDE, you can ctrl-click or drag a box around multiple controls on a form and move them all at once. How do you do that at runtime. I need to be able to create image maps based on textual copies of medical claim forms that are generated from different systems and the ability to create dynamic label controls and move a single or multiple controls and resize is required. How does MS do this in the IDE?
View 7 RepliesI 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 RepliesIs it possible to create instances of controls on a form ? Of course I mean visually , not just by code. After all, these languages define themselves as "Visual" so they should provide that possibility. It is important for the instances to be visible during design time because otherwise we could only guess where those controls might "land". Nevertheless , I have the feeling this is not possible in VB .NET but still I thought I should ask first ...

"add controls at runtime" how to add code to the controls. kinda useless with no code, ehh? all results only told me how to add the control, that's it. well, this result is different. i will teach you firstly how to add controls at runtime, then how to apply code to them at runtime
Firstly, add the controls:
[CODE]..............
Now run it. do you have a button on the form? if yes, excellent. if not, you made a mistake. try again now how to add code? you may have noticed that when you double click on any control, it says private sub button1_click(blah, blah, blah) Handles button1.click where it says handles button1.click is what determines when the code executes under what event for what control (in this case the click event for the button1). this won't work when adding code at runtime. did you notice in the above example i added a with event, and addHandler? this is what creates the handler (same as Handles button1.click)
Now we add the code for the runtime control
[CODE].........
Above, the addressOf button1_click tells the program to execute the sub button1_click when the button is clicked on (as determined by .click) but i know what you're thinking! your thinking "why would we even BOTHER doing this at runtime? isn't it easier to do it at design-time in the first place?" yes it is, providing your not writing a plugin. plugins are code based, not GUI (also reffered to as WYSIWYG). to update existing forms using plugins, you need to use this method.
is there a tutorial (i looked, couldn't find) on adding controls at runtime?

I did something that when I now load my program(VB 2008), my controls; combo boxes, buttons, progress bar, etc. look like they are from VB 2005 or like VBA buttons, not the rounded edge buttons of 2008.

I was wondering if there was a way to dispose a control that i generated at runtime in a diffrent block of code, The reason why i can't dispose of the control in the same block of code is that the controls settings depend on what the user imputs.

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 attempting to move all controls on a form down or up by the height of a menubar depending on whether it is visible or not.

How do you position controls loaded at runtime to align middle? I'm not looking to match the x y coordinates as the heights vary.
For example loading 2 text boxs and 2 labels.
