View 2 RepliesAccess Controls After Creating Them At Runtime?
Jul 1, 2007I 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)

View 4 RepliesCreating A Container Control Out Of A UserControl Can't Access Controls At Runtime?
Oct 16, 2009I 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.
View 12 RepliesCreate A Datatable Dynamicly And Use A Datagridview?
Jan 9, 2010I want to make 2 planning forms, one for persons and one for materials. The most ideal situation is when it can be in 1 form and switched by using an option field at the top.
- The information is coming from a SQL 2008 database.
- Vertical the persons or materials must be shown(dependent of the option field).
- Horizontal every day of the year must be shown, so the number of columns will be 365.
- At the crossing the number of hours must be shown.
- The form must be build as fast as possible.
I tried to create a datatable dynamicly and use a Datagridview. The advantage is the information, which must be shown, can easily be changed. The disadvantage is it is slow.What is the best method to do this in VB2008?

Dynamicly Displayed DropDownList If Multiple Entry Exists In Table?
Apr 9, 2012I'm trying to create an option to select a specific entry in a SQL table if multiples exists. The Sub listed below is for a textbox (MOTxt) and a button (GotMO) for checking an MO# to pull from SQL. Based on the number entered, will populate other text boxes on the page with that row's data. There are exceptions to this, where the MONumber will be entered more than once with different data associated with each entry. So, here's my situation. If we have a duplicate MONumber listed in the table, it will populate the textboxes with the first entry it finds for an update.I would like to create a dynamic dropdownlist (that displays only if multiples are found) displaying the 'Name' field entries for each MONumber found, then once the correct name is selected from that list, to then populate the textboxes with that selected datarow.Here's my code behind:
Protected Sub GotMONum_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GotMO.Click

Add Controls AND Code At Runtime
Jan 15, 2012"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.

Controls Change Look At Runtime?
Mar 10, 2010I 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.
They look like vb 2008 controls while I am in design view, but then they change their style when I run the program..

Generating Controls At Runtime
Apr 29, 2010I 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. For example if i generate the control on a timer tick the code would look like this,

IDE :: Adding Controls At Runtime / Where Goes App?
May 18, 2009In 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?
Moving .NET Controls At Runtime?

View 1 RepliesCreating An SQL DB Connection During Runtime?
Nov 22, 2009Needing pointed in the right direction. I am fooling around with data sources and connections per homework and what I'm looking for is creating an SQL DB connection during runtime. I know that you can add a data source in design by going through the Wizard but what if one would want to create the connection, adapter, and dataset during runtime? Where would you start?
I have cruzed the net looking for some form of a tutorial to just get me started, I don't need it all completely outlined but I need to know where and how to start and what I need to declare the connection, string, and dataset as. I have seen a lot of information using VB6 but nothing that I come across seems to work.
My basic questions are:Do I have to create a seperate class for the database connection?How do I delcare the nuts and bolts of the connection,adapter, and dataset?If a seperate class isn't required then where is the most realistic place these items would be created?
