i want to implement undo/redo function in icon editor, im try to use arraylist or Stack to hold current icon or picturebox image when mouse up and left mouse is not press. i dont know exact place to put the Stack for push.
View 2 RepliesI understand that implementing an UnDo/ReDo function can be complex using Stack operation/XML serialization.
That is why I have started to search for commercial tools/components, but I could find such tools only for RealBasic, not for VB.net. Does anyone know where to get such tool/component, or has good example code to include various undoable operation into an Undo/Redo function, that means undo operation for datagrid and chart manipulation (similar to a spreadsheet application).
how to implement undo/redo in an application? I've searched the web, and most I found don't work properly or just clear the textbox.
View 9 RepliesJust finished a database for stock management system in local terms and language. All according to their request and agreement. Now they need me to add undo/redo functionality to the application and I just dont know where to start. I am looking first for a general tip on where to begin:
I have one form, for e.g., that manages their stores. Then another for catagories...now they need the undo for all this things and am not sure if it is even possible cos datas are related.
i have written code for undo and redo operations code for undo operation

View 19 RepliesI'm trying to setup undo/redo for changes to a datagridview, but am having a problem with capturing the cell value before it is changed. I am currently using the CellEnter event to capture the original value, which is fine if only one cell is affected. However, if the user selects multiple cells and goes to cut the data (Ctrl-X), CellEnter does not fire for each of the selected sells, only the ones moused over it seems. Is there a better way to capture each cell value before their CellValueChanged event fires?

I was wondering if there is a way to modify the limit on the number of undo/redo actions a RichTextBox is capable of performing. It seems as though the limit is around 100, and I really need to increase this because of the demands of my application. I have text formatting (Bold, Underline, etc.) in my application, and since you can change the font of the text, I need to loop through the characters in the SelectedText one-by-one and apply the correct formatting to them in order to prevent any errors from appearing. Every time a single character is formatted, it counts as an action. As you can imagine, this quickly adds up and therefore makes my undo/redo features not as useful as I'd hope with the 100-action limit. Does anyone have any suggestions for me?

View 2 Repliesbasically add and remove text and selection information from a stack. Result: When using Undo/Redo the selection got messed up, the text moved, sometimes causing lag of epic proportions. I need a way of having complete and smooth undo/redo class for storing all information I would possible need.How to know whether or not to add an undo stack is easy, I just checked if the user clicked in the text or moved using the arrow keys. As soon a previous marking was given for "next text change needs to be backed up", it was backed up. At that point I stored the RTF and selection start/length. What do I have to store of a RichTextbox control to be able to restore it to a previous state, and how can I reset it back to a previous state? See it as having a "RichTextBoxState" class:
Public Class RichTextBoxState
Sub New(ByVal RTB As RichTextBox)
Me.text = RTB.RTF
Me.selectionstart = RTB.SelectionStart
[code]....
After restoring it must display the EXACT same thing as when it was saved as a state.
After getting the code below from here, I would like to learn how I can easily copy/paste and undo/redo actions. The code below allows a person to "draw" on the image.

I have created a Form, added a MenuStrip to it and inserted the standard Items. My question is that I know some of the options won't work like 'Save' and 'Save As' but how do you make ones like 'Open' 'Exit' 'Undo' and Redo' work when start debugging?

View 8 RepliesI am working on a Notepad like text editor and I'm trying to put an Undo function in it.

It doesn't have do remember all the past actions, I just want it to undo the last action even if the last one was undo... For now I have a button in a tool strip menu (tsmAnnuler) and my richtextbox (rtbZoneTexte).

View 1 RepliesI have a vb.net 2008 application which has its corresponding icon.
The icon shows correctly except in the taskbar when the "small icon" setting is on.
My vb.net project includes a .ico file which when I see in the IDE includes 16x16, 32x32, 48x48, 64x64 and 256x256 bitmaps, in 4, 24 and 32 bits, also 3 .png images in 256x256 32 bits each.
I made the icon myself simply using a 64x64 bitmap and then converting it to .ico, and assigning it to the application in the project properties. I thought windows would use and escalate the corresponding image, it shows even in the file explorer properly in the small icon form, but not in the taskbar.
as encoding text to Unicode in the textbox, I mean an option, such as Notepad.exe?
