Get An Image From Clipboard And Save It To A File?
Feb 12, 2011Im trying to get an image from clipboard and save it to a file (.bmp)
Here is my
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Private Const VK_SNAPSHOT = &H2C
[Code].....
Btw (For the first code)If I press the Button the first time and i paste it manually(ctrl+v) to the paint the printscreen image is appeared.Also If i debug the code it works perfectly and it produces the .bmp file.
So im thinking its a timing issue , so I put a sleep(3000) after the keybd_event(VK_SNAPSHOT, 0, 0, 0) command and it still doesnt work.
VS2010: Debug And After Compilation - Monitor The Clipboard And Save Its Contents To A XML
Nov 9, 2011I have seen a different behavior before, but this time my application just doesn't work properly when debugging, while it does everything perfectly after compilation.
My project is beginning and does just one thing: monitor the clipboard and save its contents to a XML. It has just one form (frmMain), which, when loaded, puts itself in Windows clipboard listening, via WIN32 API. Then, whenever receives a message, the form has to check if it's from clipboard and, if so, saves the actual contents.
The code is below:
Public Class frmMain
Private Const WM_CLIPBOARDUPDATE As Integer = &H31D
Private XmlDocument As System.Xml.XmlDocument
[CODE]...
So, as I've said, after compiling, everything works perfectly. However, when debugging the "AddItems" function is never called. I set a stop point in the line Win32 API is called (in frmMain_Load) and the execution NEVER STOPS THERE! Debugging line by line, I found out that after executing some lines from frmMain_Load, VStudio just jumps to WndProc and never comes back to frmMain. I mean, the form is shown, and the rest of its initialization code is never executed. Because of that, my form is never added to clipboard listening (this command is at the end of frmMain_Load) and, consequently, all messages my window receives are not from clipboard, and, therefore, nothing is saved.
Is it normal to VStudio just bypass some code because a event triggered other method? This could lead to lots of complications and it's not consistent with after compiling behavior. A proof that what I said is actually happening is this: I passed the last 5 lines from frmMain_Load (where the Win32API is called) to the beginning, so my program would call the API before initializing the XML file. OK, now what I have: the API is called, but the XML commands are never executed. Consequently, "AddNewEntry" is called, but I have a null-reference error, because my XML was never initialized. Have you ever faced that bizarre behavior? What can I do so my debugging is correct and I don't have to compile my program for each test I want to do?

C# - Retrieve A DataGridView From The Clipboard (It Ends Up Being Null In Clipboard)?
Jul 21, 2010I am unable to read a pasted datagridviewrow object from the clipboard. All I want to do is, when a user has the entire row selected and copied, I would paste that row into the clipboard as a DataObject. That works just fine but when I attempt to read that DataObject (after the user clicks Paste) the DataGridViewRow that's saved in the clipboard always has a value of Nothing. Here's the code I'm using for Copy and Paste.

.net - Save A Copy Of An Object And Restore It Later
May 12, 2012I have a form which has a ListView and buttons to add/edit/delete items from this list. It has a save & a cancel button. On pressing the cancel button, I want to revert all the changes that have been done in the current form. So, while loading the form I keep a copy of the original list like below.
backupMyListView = MyListView
In the cancel button code, I do the opposite.
MyListView = refMyListView
Whats happening is that, the original listview is never restored because everytime MyListView was updated, backupMyListView also was getting updated.
How do I restore the original ListView on pressing the cancel button?

Application.Settings VB 2005 - Save Arrays Using The Settings System Object
Jan 14, 2009I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.
View 3 RepliesFlattening An Object Hierarchy Using A Shim Class - Initializing Derived Object Properties From The Base Object?
Jul 10, 2010I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
