I have to modify an old VB6 program that uses ActiveReports 2.0 at work and I am having some problems (BTW I have never used this program before and only have a basic knowledge of VB6)...
I have to make some text boxes biggers which is pretty easy to do but as soon as I move them a whole section of text (and not simply the content of that text box) disappear.
I have noticed that it was in some sort of section (sorry, I don't know how they call that) which englobed those text boxes so I made it bigger and that made no difference.
What could be causing this?
Thank you!

It sounds like the TextBox is inside a UserControl. A UserControl is created by a developer, and is basically one control with any number of other controls in it. You can check to see if there are any User Controls in your project in the Project Explorer (Ctrl+R).
One way to know exactly what class the control belongs to is to open your form in design mode (Shift+F7), click on the control, and look at the Properties window (F4). The drop-down list should show the currently selected control's class name in bold, then the name of the object.
What is the control's class? If it is anything other than TextBox, then this would explain the unexpected behavior you experienced.

Windows Form Control
When I click on a cell in excel i will lose focus to the windows form, i will need the windows to be together with the worksheet, but i can't use showdialog.
Thanks for the help in advance.
From your answer it is hard for me to figure out if you we are looking at a code solution here or something more high level, so I am going to assume that you are looking for a code solution, please correct me if I am wrong.
Have you considered using an OLE object or ActiveX?
There is an example from Microsoft here, how to develop an ActiveX control. (Here is some other walkthrough that I found helpful).
Just to give you a hint how it (the example mentioned above) looks like, here is the screenshot of the compiled example that I added onto the excel sheet:
ActiveX control can be added both manually, or by code, so I could imagine that you could also provide a COM Excel Add-in that would add some buttons onto the ribbon, that when pressed, would add the desired controls onto the sheet.
I am creating a property sheet shell extension and want to have a little icon to set off my property tab from the standard system tabs. Unfortunately, my icon is being rendered almost entirely in grey.
Original image:
In the property sheet tab:
At first I thought this was somehow my problem, but then I saw that TortoiseSVN appears to have the same problem:
This happens in both Windows 7 and Windows 8.
Does anyone know why these images are appearing so muted? Also, does anyone have any hints on how to make the icon look good in spite of this colorlessness?
The PropertySheet function initialises its tab control with a 16 color (ILC_COLOR) ImageList and copies the supplied icon for each page into it. There doesn't seem to be a way to override this and supply your own ImageList (or to specify the bit depth of the created ImageList). Presumably this is a legacy of the original Windows 95 code that never got updated as things moved on.
Instead of Property Sheets, you can use Tab Control, which makes tabs management more flexible and clear. And of course you can use any type of icons, because you have to create your own ImageList.
Here you can read about Tab Controls:

And here you can access example usage of Tab Controls:
Icons in Win32 Property Pages are ugly - 4 bit icons
how can i find the specific button on design mode where i have several buttons ie: hundered of buttons so that they all like spaghetti and one button may be under another button or a groupbox (i might be playing with the visibilities ) and i want to see my button number 83 on the design. how can i see him? where is he hiding? :) i use visual studio as an IDE. thanks.
MessageBox.Show(" where is the specific button? i know that he is somewhere on the form but cant distinguish it on the design since its somewhere under something i cant find it");
Use Document Outline (View - Other Windows - Document Outline)
Just pick the button from the tree and voila.
PS: this works for other types of designers (WPF/Silverlight, ASP.NET)
You can access it via the Properties Window. There is a drop-down that will list all of the items in your form in design mode.
Then use the drop-down. The drop-down will list all of the items on your form so you will scroll through the list to find Button number 83.
Images were pulled from MS Visual Studio: The properties Window which contains an explanation of the window.
Have you tried using the properties window?
What is the best way to create a view for a single control that I need to load into a Shell region in a Prism app. I know I can wrap the control in a UserControl, but I suspect there may be a better way.
I am working on a demo app to learn Prism 4. Each module will load a navigation button into an ItemsControl in a region in the Shell. These navigation buttons will function like the Mail, Calendar, and other buttons in Outlook.
I am creating the view in each module that will hold the module's navigation button. The simplest way to create the view seems to be to wrap it in a UserControl. My question is this: Is there a better way to do it? Thanks for your help.
If you need graphical control, what you are doing is the way to go. If you find yourself making all of the buttons look the same (copy - pasting) you might find that a menu registration service is the way to go.
You'd have a service like IMenuService that you register with your container and modules can come around and register menu items to. You can then create buttons for the module. I've provided a sample for this here:
http://dl.getdropbox.com/u/376992/CAGMenus.zip
Your question, though, seems to be about whether or not you need to wrap a control in a UserControl to register them with a region? If that's the question, I believe the answer is no, although you might amend your question to tell us what you are running up against that makes you think this.
I ended up wrapping the control in a UserControl, and it seems to work fine. I am still interested in seeing if there is a better way to load the button, so I will hold this question open for a few days.
Edit 02/22/2011: I tried using a control without a UserControl wrapper, and I got the following error:
Library project file cannot specify ApplicationDefinition element.
I wrapped the control in a UserControl and the error went away.
I inherited the prototypical corporate application with a person form (with address, phone, etc).
Now on that mentioned person form one label+textfield is a child of the form itself and not of the panel it visually belongs to.
How can I change a control's parent from form to an existing panel in VS 2008 designer?
Update:
Ah, it seems to be a problem with the super magic custom group box control my beloved cow orker left for my pleasure. Dragging into a normal group box works ...
Update 2:
With the help of the Document Outline I can see that the custom "GroupBoxExt" we have in the application is defective, dragging a control onto the panel (or just changing position of a control on the panel) assigns it to the form.
Update 3:
Now that I new what was wrong (thanks for the document outline tip) I went of to google and found a custom group box on CodeGuru. The author of that artilce found out you'd need to decorate your custom panel with
[Designer("System.Windows.Forms.Design.ParentControlDesigner, System.Design", typeof(IDesigner))]
to make it behave as a nice container.
If you're looking to do this in the designer, what you're looking for is the Document Outline panel (it's under the View menu under "Other Windows"). From there you can drag controls by their name in the outline and reassign the parent.
Hope this helps!
I'm not sure exactly what your asking. Can you try clarifying the scenario a bit?
But if you want to change a controls parent, all you need to do is make that control a child of the panel using the Controls property.
myPanel.Controls.Add(target)
This should update the parent of target to be myPanel.
If you're attempting to do this via the designer, all you need to do is drag the target control onto the panel and that should take care of it.
