• Internet Explorer Development Toolbar Button Handling

  I've added a button to the toolbars. I've implemented it as a COM object. It works. (enough showing off) I'm able to get IShellBrowser and IShellView Interfaces - but they don't really help. ref: http://msdn.microsoft.com/library/default.asp url=/workshop/browser/ext/tutorials/button.asp If your COM object needs to access the Dynamic HTML (DHTML) Object Model of the page that Internet Explorer is currently displaying, you must implement IObjectWithSite . I want to access the html source and the url being displayed. Where can I access this info Check out http://msdn.microsoft.com/library/default.asp url=/library/en-us/dnwebgen/html/bho.asp It shows how to get the html sour ...Show All

• Smart Device Development How to detect if a Smartphone application is put in the background?!

  Hi there! Following problem: I have a Smartphone application which has main window which consists of a single (docked) TreeView. I need to perform certain tasks when the application is put in the background. That is when the Escape/Back key (KeyCode 27) is pressed. However it looks like and TreeView / ListView eats up that KeyCode. I tried a number of things but i simply can't get the escape key event. This is probably because the escape key might also be used to collapse tree nodes. So how on earth can the application figure out, when it is put in the background when neither the TreeView nor the Form fires the KeyUp event for the Escape/Back key Do i have to do some dodgy constructs with the OnDeactivate / OnMinimise event ...Show All

• Visual C# How to delete a control during runtime?

  Hi, I would like to know how to delete a control when the user presses the Delete key on the keyboard (For example, there is a label in the form, and the user clicks on it and presses Delete). I was trying to use the KeyEventArgs but it always gives me an error message stating that it is not set to an instance of an object.. pretty much in the same steps for implementing the keydown events - just go into the events property of the control and scroll down to "PreviewKeyDown" and double click it to create the event ...Show All

• .NET Development SyncLock: Any benefit or downside to using a ReadOnly Shared Var as lockobject?

  Public NotInheritable Class Foo Private Shared ReadOnly _LockMe As New Object() Private _MyObject as MyObject Public Sub Run() Me._MyObject = New MyObject() SyncLock _LockMe Me._MyObject.MyProperty = 3 End SyncLock End Sub End Class Given the above example, are the any benefits, downsides, gotchas to using a ReadOnly Shared var as a lockobject Or will it act exactly the same as a non-read only Thanks! Whether it is ReadOnly or not makes no difference to how it affects the locking, however it is good practice to declare it this way so you don't accidentally write code that swaps the object for another one. However declaring it as Shared makes a big difference. ...Show All

• Visual Basic Communication to LPT1 and Com ports

  I'm relativly new to visual Studio .net and have not had a lot of expereince with programming applications to read and send data to Com ports or LPT1 ports. I am contemplating rewritting an application currently written in Access to track data that comes from a scale. The LTP port receives prompts from the scale signifying that there is data that is going to be transfered. That in turn opens Com port 1 and the scale sends a string to the PC, the PC evaluates the string and pulls out the data location that contains the weight and the operator and then returns the subtracted weight out Com port 3 to the scale to be posted on the display. How would I open the Com ports and establish this communication to send and recieve the data, and ...Show All

• Visual C++ Class object Creation

  hi , i have a doubt . when does the object of a class created.. is it created after the call to one of the constructor. or before the call to constructor. i think that object is created before the constructor . and initialization of those objects during constructor execution.. plz reply, manish It depends on what you call "created". The memory for the class object is allocated by the new operator. But it isn't yet fully ready to be used until the constructor has finished executing so that the object is properly initialized. The very last thing that happens in the constructor code is execution of a bit of code that the C++ compiler generates that puts the true v-table in pl ...Show All

• Windows Forms Hide cell error in a DataGridView once the error is corrected?

  I have a DataGridView displaying rows imported from a text file which have errors so they can be corrected. If I correct a certain cell, the red exclamation mark stays when I move to the next row. Is it possible to hide the exclamation once the cell in question has been corrected I tried doing that in the cells validated event, but it doesn't work. Do I have to specify validation code for every column What I really want is this to be automatic - e.g. if the dataset specifies a column cannot be null, a column with a null value appears with an exclamation mark. If the user then types something in said column, I want to exclamation mark to disappear. ...Show All
