I create like this
htextbox=CreateWindow(L"static",L"",WS_BORDER|ES_MULTILINE|WS_CHILD|WS_VISIBLE,50,0,
100,50,hWnd,(HMENU)ID_STATIC,hInst,NULL);
But I can't write text there.
What is wrong?
You say that you want a text box which makes me think you want the user to be able to edit the text. In which case you have the wrong window class. The STATIC window class is for labels. What you want is an EDIT control.

I feel kind of silly asking this question as it seems really simple, but how do I create a text box that I can type in instructions and stuff like that. I don't need the user to be able to change it, it is just to give instructions. I tried the label, but it only allows one line. I need something that can allow about a paragraph or so. Similar to the box in an installer that describes what the program does. What did I miss?
You can use a label but set its AutoSize property to false. This allows you to size the label as you wish and it will automatically wrap the text to fit.
You can also anchor the label to the parent form to have it automatically resize and reflow the text if the user resizes the parent form.
You want a text box, but set its Read Only property to TRUE, and maybe Enabled to FALSE
I have a CListCtrl control that has 2 columns and any number of rows. I want the user to be able to click(or maybe double-click) a "cell" and be able edit the text therein.
What I mean is that I want to be able to click and edit any of the places where it says "TEST" by clicking on the text to make it editable.
How should I go about this? I suppose I should use a mouse click event but how would I make the cell editable?
This looks like a list control in report mode, which is different from a list box. A list box doesn't support editing contents at all. You can write code entirely on your own to get the contents of a line, copy that to an edit control, display the edit control exactly where the existing content was shown, allow the user to edit, and copy data back when/if the user hits return.
A list control allows editing of one (and only one) field. If you want to support more, you have a couple of choices. One would be about like above, creating your own edit control in the right place. The obvious alternative would be to look up one of the many grid controls. CodeProject has a number of variations.
I have a Listbox where all cells are editable.
While the user is typing text in the ActiveCell (Textfield) she may decide to paste text.
I would like to examine the paste-text and perform different paste operations depending on whether it is multiline or not.
Is there any way to create an EditPaste MenuHandler specifically for ListBox1.ActiveCell?
You should be able to use the keyboard async command and intercept the paste command in the Listbox.CellKeyDown event. Then take a look at the clipboard object to see what text it has in it.
Kind of a kludge, but I can't think of any other way to do it since the ActiveCell handles cut/copy/paste on its own without intervention.
I want to get the currently selected item (text, image, etc) and display in my Cocoa app's window when a keyboard shortcut is hit. Droplr has functionality like this, for example. How do I go about doing this?
For example, I want it to return "(text, image, etc)" as text when that text selected on the screen like this: http://drp.ly/JAdv
The easiest way is to write a service and assign a keyboard shortcut to it. Services are designed to do exactly this: operate on the selected text, graphics, etc. (or insert information at the selection).
NSResponder * activeControl = [currentWindow firstResponder];
Does anyone have an example of using a QWidget as an editor in a QAbstractTableModel?
I have a column which when edited should create a QCombobox with the list of choices.
The docs seem to suggest I need to write a QAbstractItemDelegate and a custom paint function but that seems overkill to simply pop-up a standard QCombobox in Qt::EditRole.
Note - the combo box contents are the same for every row and it only needs to be shown when somebody clicks in the cell.
I know this should be simple but I can't get it to work. It's easy for a QTableWidget based table - but I need it for a very large data table.

You don't need to go that far. One way is to subclass QStyledItemDelegate and then override createEditor() so that it returns your prepopulated combo box. Its setEditorData and setModelData functions will probably already suffice if you`re using basic Qt value types.
If you need something more generic that works across many different models, you can create a QItemEditorFactory that associates your editor with the correct type. This also works well with custom types.
When indicated by your view's EditTrigger, your view will get the delegate specific to the cell on which the edit is being invoked and call delegate->createEditor(...) which can then size the combo box according to the options parameter as well as set the current entry to the value specified by the model, although most of this should be handled by the QStyledItemDelegate. Thus, you won't have to worry about the Qt::EditRole directly as the view will handle that.
Did you try and have a look at the following example from Qt :

Maybe it will give you a much clearer view on the subject !
Hope it helps a bit !
