i want to make a paint sort of program and so i have read about how to add controls at runtime. but i cant figure out how to change the properties of the control... for ex, if i add a line( that is the user clicks the line tool on the toolbar) he should be able to place it anywhere on the area available, and after that also if later he wishes to select it and resize/change color etc. it can be done.

What I want to make the OpenTK window to be completly independent from whatever is going on with the other controls (for instance if button_click is Thread.sleep(10000) I dont want that my animation freezes for 10s). I want to have it in its own thread (no BackgroundWorker). The problem is I dont know what modifications should I do to get it working. It is currently initialized in InitializeComponent section. I want that all events and everything is handeled in its own thread, basically 2 "programs" in 1 form.

I am creating a program which allows the user to add some buttons during runtime. Each button can be moved, sized and added to any tab on a tabcontrol. What I would really like to do is binary serialize a class that contains the properties of each button including which tab it's on.
View 4 Repliesim 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".

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.

View 3 RepliesSo I have a query I'm doign where, at the moment, the places to search are set in stone, but the values that maybe be searched for is variable.Right now, I have a drop down menu that allows you to choose a character class. This limits the items to a specific class. Then I can filter on text from a textbox.
However, each item in the list has a source, based on the book it is published in. I want a user to be able to choose several from a checkbox menu, then pass those values for inclusion in the criteria for finding items.
The problem I'm having is finding the most concise way to do dynamic WHERE clauses. There are several examples out there, and even a couple don't seem to want to do exactly what I'm doing, and I'm having trouble determining if it will work for me.
I was trying to code a save option for my project, it's a spammer that I have created and I have made it to where people can have their own personal spam message and when they want to use it all they have to do is click a radio button and the text will appear in the text box. Now like I said I want it to save, like they make their own customizable spamming options and then save it so they want have to continue typing in the message because that would defeat the purpose of my project.
Here is the code:
TextBox2.Text = (TextBox2.Text)
RadioButton1.Text = (TextBox2.Text)
TextBox3.Text = (TextBox3.Text)
RadioButton2.Text = (TextBox3.Text)
TextBox4.Text = (TextBox4.Text)

Though it wouldn't work unless I imputed this code

View 13 RepliesI have a window that needs to run a length process. The process is threaded so it doesn't lock up the screen. However, I need this to run when the window is first loaded, not based on a button click or anything. The problem it creates is that it causes the window to stall a bit when initially painting itself. I even tried to put the call to the method in the Shown event, although it helps, it's still not perfect.

I have a little question about application settings. I have a regular expression in my code which should be customizable by the user so I made an application setting for it. The regular expression is used in a class in the project and has the following value
Dim email_regularex As String
So now I made a new Settings file in my project and gave the following value for this string in the settings file: ^([w-]+(?:.[w-]+)*)@((?:[w-]+.)*w[w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$ [URL]
So when i do this in Visual Studio 2008, Visual Studio automatically creates a app.config xml file with the right settings in it. But when I start my application and use the regular expression like this:

Whilst playing around with DataGridViews in VS I've accumalated quite a few TestDataSets within my project.
Can someone please tell me the correct way of removing these cleanly? At the moment I've been Right Clicking a DataSet (from within Solution Explorer) and either clicking 'Delete' or 'Exclude From Project'
Doing this throws up Errors in the Error list such as;
TestDataSet is not defined
TestDataSetTableAdapters is not defined
TestDataSet is not defined
TestDatasetTableAdapters is not defined
I then double click each error in turn which takes me to the actual code with the error and delete this.
I have quite a lot of TestDataSets and I'm hoping there is another way to do this much cleaner.

View 10 Replies"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.

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.

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.
