• dbdog ignore mouse down event

  I'm new to C# programming, learning it for pleasure on my own time. As an exercise, I'm creating a simple Windows program that 1) takes the mouse-down event as an 'anchor' point, 2) while dragging the mouse around continually draw a line from that anchor point to the current mouse position, 3) once the mouse-up occurs, shrink the resulting line down automatically until it disappears. Not too hard, and it works perfectly fine. My problem is that I do not want the Form to accept any mouse-down's while the shrinking logic is occurring. Currently, while the line is shrinking, I can do some more click-and-drags, and once the shrinking completes, those subsequent lines are drawn/shrunk in like fashion. I want to effectively ignore any mouse- ...Show All

• Eric White King Launching an application from within a C# application

  When you want to launch an application from within Visual Basic 2005 you use the following format: Process.Start("......"). How do you accomplish this using C# I haven't been able to find an example. Before I answer your questions I must suggest that if you have any more questions you should post them as new ones on the forum so that others are able to see them. That way you aren’t waiting for me to check on my previously commented on threads for help. As to #1... just the same way, only you add a semicolon to the end of the line (which most lines of C# code have). One other change from your line is that you need to have the () characters at the end of the two method calls ala: txtCloc ...Show All

Any suggestion Thanks, William cool answer. Tom here is a daft question, please forgive me. I'm still new to this dictionary stuff.

• chxfryer Store a reference

  I would like to pass along a reference to a structure to another class and then store the reference in that other class. If i had pointers, it would look like this: someStruct myStruct = new someStruct(...); receivingObject.ReceivindMethod(&myStruct); and the implementation... receivingObject::ReceivingMethod(someStruct* passedStruct) { localStructPointer = passedStruct; } However.. if I give the structure to another objects method and use ref to pass by reference, I can use the refenerence as such in the receiving method, but how do I save that reference so that I can access it as a reference at another time If I assign the referenced struct to a local struct, then it copies the contents... and I am not ...Show All

All the options listed under pulldown menu Edit and Find and Replace do not display any window. it just did nothing. could anyone please let me know how to get those functions back. I finally solved it. The Find window was hidden way to the left of the monitor beyound frame. I can't see it.

• TG_KG How to catch a file save on the fly?

  Hi! How can I know if a certain file is changed(saved) after someone changes the file immediately Is there an api or hook method that can be used to provide this Thanks. no I don't but you should stay away from Win32 API if you can as it degrades performance and kind of defeats the purpose of .NET and its classes! Thank you for your answer ahmedilyas! Do you know how to do that using win32 api I think the filesystemwatcher can do this: http://msdn2.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx this is in .NET 2.0 everything is in that link :-) ok, thanks. ...Show All

• Neotech Problem with Reflection: PropertyDescriptor.SetValue()

  The method it supposed to take a CustomControlDesigner which has a Control contained within it. I want to do a deep copy of it, without having to keep updating the method whenever I change the attributes of CustomControlDesigner. The problem is that the method is throwing a System.Reflection.TargetException(Object does not match target type) on the line with //*** (the SetValue method) The type names that the message box shows are always identical - I assume the problem is that the one I'm setting on the returnable object is cast to 'Object'.

• Dr Adrian Colquhoun library not registered error

  Hello, I hope someone will have an answer to this question... Using VS. Net + C# I have a a console project called implementer that communicates with another addin project. Both are supposed to send and receive a "struct" that holds a hashtable to store/change info. I got the addin to show up right and it starts listening to the events been triggered by excel. In one of the events, the addin class, via invocation, is supposed to instantiate an instance of the struct and pass it to the running instance of the implementer class which changes and modifies the info in the hashtable of that struct. when trying to send that struct (which is a dll file by itself but added to both projects as reference) I get the error message s ...Show All
