I am trying to see all the labels in Me.Controls and when I use:
For Each Control As Label In Me.Controls.OfType(Of Label)()
MsgBox(Control.Name.ToString)
Next
it only shows the labels that have NOT been renamed
Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

I recently uninstalled an IDE for a motion control system (Delta Tau) that is a visual studio based product. Now when I bring up my Visual Basic 2008 IDE that I'm using to write an HMI for the control system, the properties for controls placed on forms doesn't appear in the properties window. And if I click on properties for a form I get the FileProperties2 information, not the form control properties such as size, location, or color. I am also not able to access the controls in the VB toolbox to place on a form. The controls are grayed out and unavailable. what part of Visual Studio 2008 got broke in the Delta Tau uninstall?

I'm using a TableLayoutPanel and I want to get the control at a specific position in the TableLayoutPanel. I want to iterate over the rows and columns of TableLayoutPanel but this question applies equally if I just wanted a single control at a specific row and column.Unfortunately GetControlFromPosition(int column, int row) only retrieves controls that are visible (that is their Visible property is set to True). This is no good to me as sometimes I want to access a control at a specific position that is not visible and then make it visible.
I have had to resort to iterating over the TableLayoutPanel.Controls collection, and then get the position of each control using GetPositionFromControl(Control control) or GetCellPosition(Control control) until I find the position I want.(I'm not sure of the difference between GetPositionFromControl and GetCellPosition methods as MS documentation is meagre, but I'll ask that question separately).
When I make my form Opacity 0% everything disappears including controls that I know will happen im not dumb ok so I tried another method using Transparency Key I had success BUT my problem there is that when I have a picture box and an image IN the picture box around the image is the Form Background color so lets say I picked Maroon for Form1.BackColor, The edges of my image is Maroon
View 6 RepliesI have a form with six picture boxes on it. Each Picture Box has a button underneath it. When the button in clicked, a "Label" and "Textbox" appears. My question is, how can I close the currently open "Label" and "Textbox", when I click another button. I have a working code below, but it's not efficient. As you can see, I will have to list all labels and textboxes on the form. Is there a way to identify all labels and textboxes without naming them all. [code]...
View 3 RepliesI am having trouble finding a way to make the form transparent but the controls still visible. The only transparency I have been able to get to work on the form is
Me.Opacity = <value between 0 and 1>
but that affects all the controls on the form Is there a way to make the controls not inherit this property from the form? Is there another way to make the form transparent? I have buttons and a checkbox that I don't want to be affected by the transparency at all, and a picturebox that I do want to be able to control the level of transparency. Currently, I'm using a slider bar, and controlling the opacity of the form, but that makes everything on the form transparent. I'd actually like for the form itself to be completely invisible, and for my slider bar to control the opacity of the picturebox only.

View 2 RepliesBut I don't know if i posted this at the right place. I am making 40 textboxes inside a panel. And this textboxes I set it to visible=FALSE. Then I have another textbox named txtNoteam in which once the user will enter a number in this txtbox which is less than or equal to 40, those textboxes will be set to true starting from textbox1 to textbox40 depending on the number entered by the user. Example: user enters 3, then textbox 1 to textbox 3 will be set to visible.
I was successful in doing this except one thing, instead of textbox 1 to textbox 3 will be set to visible, it's the textbox 38 to textbox 40 will be set first. This means it will start from the last textbox to the first textbox instead of from textbox1 to the last textbox.
I need your help on what should I do for this to be able to set it to visible from the 1st textbox to the last textbox or is there any other ways of doing this?

I am working on a spreadsheet-like custom control, manually painting all cells according to its bounds and indexes. All is working fine until I populate it to upto a hundred rows (with fixed 6 columns). Basically my sheet expands itself to fit all cells, so to use it properly on a form, I use a panel with autoscroll = true and with my sheet inside. The problem is, the control flickers a lot, which I think is caused by painting ALL of the cells. Is there a way to paint only the visible area.?? So when I scroll down, the control would paint only the visible cells on that area. What I am thinking right now is to not put it in a container, but rather, put a scrollbar in my control. Then that scrollbar would then handle the setting of visible cells, and then my paint event would only paint that visible cells. I am using VB btw, .NET 3.5.. I cant put the code in here cause its separated in different classes(Cell, CellCollection, Rows, Columns, Range, Worksheet, etc.)

Still using VS 2005. My concept is to use the same form space to display different "pages", like a "wizard" where you click the [Next] button, and the current UI disappears and a new UI appears. I want to "turn off" multiple controls and "turn on" multiple other controls. Example code: -

View 7 RepliesI need to print a windows form which contains radio buttons, checkboxes, and other controls.
Printform doesn't work - even with the scrollable option it only prints the visible screen.
The PrintDocument doesn't work, because I can't add controls to it.
I can't capture the screen image, because the form occupies more than the visible screen.

I am currently developing a WinForms application in C# and require a table control that can contain other UI controls.In the following example, I would like the Links column to contain link label controls:
| ID | Name | Links |
-----------------------------------
| 1 | n1 | link1, link2, link3 |
| 2 | n2 | link1 |
Is there one I can use 'out of the box', are there any good third party ones?
Has anyone tried using controls from different sources into their application that uses winforms? Will these combination of controls work together?

I'm used to webdeveloping, and when I work with databases, I usually use some text for the Text-property of a radio button, and the row's ID as Value-property. This makes it very easy to save to databases.
Is the an equivalent in winforms for the Value-property, or will I have to identify rows based on the text in the control?

View 4 RepliesI'm writing a VB.Net WinForms application that has multiple data girds on any given form. On one such form, the data grids are loaded into split containers which in turn are located on a tab control. The load method for each data grid is threaded so that an animated "Loading" form can be shown. I would like to position the new loading form (which is smaller than the grid) on top of, and preferably in the center of, the grid that is loading. Whats the easiest way to find the grids location within the main form so that I can adjust the loading forms location?
View 1 RepliesOur shop primarily use "ADO objects" (I'm referring to DataSet, DataTable, and DataRow) for marshaling around data and manipulating it on forms and in grids. We are experimenting with creating shop-flavored counterparts to the native ADO objects so that we can impose our in-house standards on top of them. Implementing this is straightforward with one exception: I want our objects to be bindable to controls.
I'm aware of IList, IBindingList, BindingSource, etc. and have looked at and experimented with these, but I am falling short when it comes to making a class with no hard property names bindable. The native ADO objects are not strongly typed by default. You have column values that you access via the Item property (e.g. row("Age") or row.Item("Age")). The binding examples I've found online deal with strong-typed objects (e.g. row.Age). Essentially, we want to create custom ADO objects (not inherited from the native ones) that still retain their ability to bind to controls. In a grid I would expect to see columns Name, Age and Occupation from a row where these properties are exposed via row("Name"), row("Age") and row("Occupation"). This must be doable as this is exactly what the native DataTable and DataRow provide.
