• Windows Forms Slow User Defined Control

  I'm creating a custom control that has contained within it a large number of buttons. The code is extremely slow (taking about 12 seconds to display). I've had no success in making it faster. The problem seems to be centered around a single statement: Controls.Add(my_button_ctl); I tried to use the Controls.AddRange(...) member instead of Add(), but there was no speed improvement as was implied in the documentation. If I remove the Controls.Add() call (or AddRange), the display is almost instant. Is anyone aware of a way to speed up a user defined control that contains a large number of button controls In my case there are up-to 550 buttons contained on the control and I would like to get them displayed in under 1 second. The custom ...Show All

• Visual Studio Express Editions Can't install VC++ Express from .iso on CD

  I downloaded the Visual C++ Express .iso file and burned a CD ROM so I can install it on a machine that is not connected to the network. The PC has VS6.0 on it but nothing after that. I successfully extracted all the files to a directory on my hard drive, then clicked on setup.exe. Part way through, a box pops up telling me to "insert disk" because setup is looking for dotnetfx.exe. It wants me to insert the "Microsoft Visual C++ Express Edition - ENU disk1" but all I have is the CD ROM with the .iso. The dotnetfx.exe file is there, under wcu\dotNetFramework\, so I don't know what's going on! The "insert disk" window will only accept a path to one of my CD ROM drives... if I try to point it to the location ...Show All

• Visual Studio Express Editions Detecting keypress outside the program windows?

  Hello, I am trying to make a keybind program, but in order for it to work, I have to check if a certain key is pressed while another window has the focus, and then simulate what the users has entered. I am successfully able to simulate keypress, but I cant manage to detect it outside the main window. Its a keybind program for the game Grand Theft Auto: San Andreas, so I could check if the name of the window contains "San Andreas", then check if a certain key is pressed while that last windows has the focus, it would be helpfull. Ive searched for ages on Google and MSDN, and I am not able to find anything. Help would be apreciated. Thanks. Actually im trying to read key input in another window, and this window isnt mine...

• Visual C++ Code generation bug when throwing exceptions in C++/CLI with optimizations.

  While writing a C++/CLI project using exceptions I've encountered a bug( ) related to stack unwinding and deleting local variables in unreached parts of the functions on the stack. The following code demonstrates the bug. Please compile with Visual C++ 2005 with /CLR and /O2 flags set. In debug mode, the stack unwinds and the runtime does nothing with the local variable str . In release mode, the runtime attempts to destruct str , even though it has not been used. A workaround which in some cases appears to work is to declare str in the scope of the function. In our case this would be very inconvenient. Has anyone experienced something similar We could not find anything on MSDN or on Connect. Output in debug mode: Main test functi ...Show All

• .NET Development MSDiscoCodeGenerator error

  Hello: I can (seemingly) sucessfully add a web reference to a web service in the same solution. The reference.map, *.wsdl and *.disco files are generated correctly in the correct places. However, I get the following 2 errors after adding: 1. The reference is not added to the namespace - i.e., I cannot access the methods in the proxy class programatically at all. If I double-click on the web reference in the Solution Explorer, it just jumps to the parent namespace in the Object Explorer, but no new "child" namespace is created for the newly added reference. 2. If I try to update the web reference, I get the error "The custom tool MSDiscoCodeGenerator failed. Object reference not set to an instance of an object.&qu ...Show All

• Visual Studio 2008 (Pre-release) XamlWriter.Save and StreamGeometry

  Is there a reason that XamlWriter does not serialize StreamGeometry   Even when serializing a GeometryDrawing that contains a StreamGeometry, the child StreamGeometry node remains blank, even though the child Pen and Brush of the GeometryDrawing are correctly serialized. Is this behavior by design Thanks, Fred Vandervelde Thanks Adam! As it turns out, the culprit was StreamGeometryContext.BeginFigure. I had been calling it with 'isFilled = false'. Once I flipped it to true, my StreamGeometries were serialized as expected. Thanks for the response! F. ...Show All
