VS 2010 : Adding New Control To A Form?
Nov 16, 2011
I wrote a simple application to help me with my work the interface looks like this:i use a button to add a new custom control every time by the following code :
Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim NewGard As New GardControl
NewGard.Left = x
NewGard.Top = y
[code]....
but after the form's lower end is reached, the added controls appear like this:spaced greatly & exponentially from each other despite the y coordinate is accurately increased every time by 41?

I have added a freshly compiled ObjectListView.DLL to my VB.NET project and I've added a ObjectListView control to my form. But, thus far I have been unable to do anything with it except make it throw exception errors of various kinds. I know I'm not supposed to use it using the same syntax that ListView uses, but the documentation for this control is as well developed as MSDN's for ListView--which is to say vague to nonexistent. I can't use ListView because it gives me no control over row height and cell padding. Both need to be minimal, but with the defaults used by ListView, you could move in and and make a living between the entries. Too much space. I need things compact because the application I'm developing needs all the real estate it can get for other purposes.

I've got a TCP Listener running on a separate thread. I want to have it log the incoming and outgoing messages in a list on the form instead of in message boxes. I've been reading about multiple threads, and I know there's something extra I need to do because form controls are not thread safe.
Unfortunately I've tried several tutorials on delegates and invoking but it still doesn't seem to insert the log items to the list. I even spent $60 on this Mastering Visual Basic 2010 book to "Build Rich Client and Web Applications with Visual Basic", but there isn't a single chapter on how to handle multiple threads.

I've tried following the Microsoft instructions to add multiple Textboxes to my form, but just cannot get it to work.Thus, I've deleted everything I wrote, so I don't have code to post. Is there a very simple way to add multiple TextBoxes to a form and be able to index them? If it's too lengthy, Is there a workaround?

I am playing around with Drag and Drop, and I am having an issue with AddHandler. I am creating labels and displaying them on a form. Before I add each label to the form, I add 2 event handlers (DragEnter and DragLeave). When I run the code, it hits the first event handler (DragEnter), but doesn't hit the second event handler (DragLeave). Either I have coded something wrong, or the second handler is not being added.
Here is my code (note this is just something Im playing around with for learning):
Public Class Form1
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
[Code]....

I've tried a couple things to add items to a combobox (I've also Googled a lot but haven't found anything for VB2010) and on top of that, how to make it so that if the user selects 10ms, it changes the Timer1.Variable to 10.
Here is my progress from what I found on Google
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
ComboBox1.Items.Add("10ms")
[Code]....

Is there any way to add new properties to a control? For example, I'm using an "OvalShape" from Microsoft's Powerpacks, these are designated as "Cells". I would like to add properties to the class itself (if I had a physical class to edit) for different processes such as "energy level", "family number", "mutation", etc. General variables that are either Boolean, Integers, or etc. If there isn't a way to edit the powerpack class itself, is there a way I can use the ovalshape power pack in my own class and add extra properties to it myself?

This sounds like a dumb question, but I'm using VS 2010 Express edition and cannot find where to add a new Windows form. The templates provided don't indicate a Windows form . Are they called something different in this version of VS?

[url] How is this done? Is it a control of that form? Or is it a splashscreen or something like that?. I've tried by doing that with another form instead, but the first form will get unfocused, and i want the main form to be always focused.

i frequently have troubles with the dock property. it seems that either the order of creation or adding to the parent control determines whether or not a control's dock property supersedes another's. e.g. a control with the dockstyle fill will overlap with another docked control on the same parent. does anyone know what the rules are to determine how docking will behave; particularly in dynamically created GUIs?

I have an asp.net usercontrol which represents a "popup" dialog. Basically, it's a wrapper for the jQuery UI dialog which can be subclassed to easily make dialogs. As part of this control, I need to inject a div into the page the control is used on, either at the very top or very bottom of the form so that when the popup is instantiated, it's parent is changed to this div. This allows "nested" popups without the child popup being trapped inside the parent popup.
The trouble is, I can't find a safe way to inject this div into the page. A usercontrol doesn't have a preinit event, so I can't do it there, and calling Page.Form.Controls.Add(...) in Init, Load or PreRender causes the standard exception "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I thought I had found a solution by using. ScriptManager.RegisterClientScriptBlock(Page, Me.GetType, UniqueID + "_Dialog_Div", containerDiv, False) which seemed to work well normally, but recently a coworker tried putting an UpdatePanel inside the dialog and now she's getting the error "The script tag registered for type 'ASP.controls_order_viewzips_ascx' and key 'ctl00$ContentBody$OViewZips_Dialog_Div' has invalid characters outside of the script tags: . Only properly formatted script tags can be registered."
How are you supposed to add controls to the pages control collection from inside a user control?

I've created a form that has a timer control. When this form loads it counts down before running a procedure. Simple.
Now I want to subclass this form in a new VB.NET project to so that another form inherits this form (an it's timer functionality) and runs a different procedure on this new form.My problem is that when I create the form in my new project the timer from the parent form seems to be running and when it's time is up it runs and code and crashes the VS environment.
I've searched high and low but have only found references to making sure the timer is disabled at design time. I've done this on the parent form but in this parent form's Load event the timer is enabled.... the purpose of the form. So when the child form loads it is enabling the timer. How can I work around this? Can I enable the timer from the child form? Timer is not visible when the child form loads so how do I manipulate it?

I have a form that I want to have a control box so you can close it at any time but I don't want it to be movable from its origainal position. It opens maximized and I want it to stay maximized. I've tried all the different FromBorderStyle options in properties and I've tried all the SizeGripStyle properties though I can't say I've tried all the combinations possible between those two but whatever I've tried I can always click on the border at the top and then the form breaks free from its starting position and when it does the vertical scroll bar disappears.
How can I have this form stay in place with the vertical scroll bar and the control box and not break free from its starting position if someone clicks on the border at the top? If I try FromBorderStyle None then I don't have control box to close it. I was looking at the form events list and I noticed when I break the form free by clicking on the border that that is a ClientSizeChanged event.

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

I am programmatically creating a Tabcontrol and adding Tabpages to it. To each Tabpage, I am adding 2 Pictureboxes (Testpicture1 and Testpicture2). The amount of Tabpages depend on the amount of frames in my .tif file. So, each picturebox holds an image (frame) from my .tif file sequentially from˜0 to totalpages. All good so far. I can click each tab and correct images are displayed in correct order. The problem is that when I drag a control (picturebox) and try to add it to Testpictue1 or Testpicture2 it does not work correctly. At first I thought the it didn't work at all, but when I checked each Tabpage I have found that all pictureboxes got added (draped) to my last Tabpage, in this case Tabpage4. So this is puzzling. Even though each Tabpage holds 2 Pictureboxes and they display the correct images yet the picturebox is added to the Testpictue1 or Testpicture2 of the last created Tabpage? [code]

When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting?I don't want to type those event handler subroutines every time!
