• .NET Development Binary serialization to NetworkStream doesn't work from remote computer

  Hello, My problem is that the following code works fine when the client and server application are on the same computer, but fails, if they are on separate ones. The thing seems going well until the 'Deserialize()' call. During debugging I see the client's IPEndPoint is correct, the NetStream's members look ok. Than at 'formatter.Deserialize(netStream);' call it simply dies. Not throwing exceptions, not exiting the application (especially this message-receiving is running in a separate thread, it can be that this thread exits only, but no error message at all...), but if I put a breakpoint on the next row, it never reaches it. So here comes the code: Socket connectedSock = null; connectedSock = recSock.Accept(); IPEndPoint client = (IPEnd ...Show All

• SQL Server Select GetDate() Just the month or year

  I wonder if someone can help me with getting JUST the month and year from SQL DB. Using the Select Getdate() Statement. If I need to use another one that would work that would be appretiated as well. Thanks! There are several ways to accomplish your task. In Books Online, look up [Functions], then [Date and Time Functions]. To retreive the current month as a number, use: SELECT month( getdate() ) SELECT datepart( month, getdate() ) To retreive the current month as a name, use: SELECT datename( month, getdate() ) And to retreive the current year, use: SELECT year( getdate() ) SELECT datepart( year, getdate() ) ...Show All

  Hi All, I have an owner-drawn a list box.I'm drawing the things I required properly. But the problem is I have a timer and I need to update some specific items in the list box.

• Visual Basic Continuously adding buttons during runtime and a Happy New Year to you. :-)

  Hi. I want to build a program which can add its own buttons. However, I only ended up adding one button, and I don't know why. Here's the code: Dim i As Integer Dim ButtonMade As New Button Private Sub Button1_Click_2(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click i += 1 ButtonMade.Text = i.ToString ButtonMade.Left += 100 AddHandler ButtonMade.Click, New System.EventHandler(AddressOf ButtonMade_Click) Me.Controls.Add(ButtonMade) End Sub Private Sub ButtonMade_Click(ByVal sender As Object, ByVal e As System.EventArgs) MessageBox.Show("Hello") End Sub I couldn't figure out why it just keeps on adding just one button, and when I try to add another one, it just transports the previously made ...Show All

• Internet Explorer Development Powerbuilder IE7 embedded webbrowser control

  Our Sybase Powerbuilder application contains an embedded Microsoft Web Browser control, accessing web pages on a local webserver. After installing IE7, dropdown controls within embedded web pages are no longer selectable. The options appear, but none are clickable. I have stripped the html code to a bare minimum, so it does not appear to be related to this. I have also tried noddy apps in various versions of Powerbuilder with the same results. On a machine with IE6 however, all is fine. Our customers have recently installed IE7 with the same result in the deployed application, and have had to revert to IE6 to resolve the problem. I have seen various issues with the IE7 install affecting VB6 apps, relating to shdocvw.dll a ...Show All

• Visual C++ What is Visual C++ equivalence to C#'s "is" operator?

  I'm trying to convert some C# code over to C++ but cannot figure out what's the C++ "is" operator. C# code: Control m_control; if (m_control is Control) { ... } I've searched and found this article but it's outdated and does not work with Visual C++ 2005: http://msdn.microsoft.com/msdnmag/issues/02/02/managedc/ In which the author defines the following template: template <typename T1, typename T2> inline bool istypeof ( T2* t ) { return (dynamic_cast<T1*>(t) != 0); } bool isanInt = istypeof<int __box>(someBoxedInt); I've tried all following with no luck: if ((Ojbect^)m_control == (Object^)Control) if(m_control.Equals(Control)) Any help would be appreciated.

• Visual Studio 2008 (Pre-release) Subscribing to a PageFunction's Return event from another Window

  I have a series of PageFunctions and two Windows. One window is the main window for my application, and the other is a window that just contains a Frame. From the main window, I launch the second window, and pass a PageFunction to it that it navigates to. Before creating the window I subscribe to the PageFunction's Return event. The PageFunctions work and allow me to navigate through each one. When I reach the end I call OnReturn(), and it calls OnReturn for each PageFunction along the way recursively, exactly like the sample code. However, the Return event that I subscribed to from the Main Window is not called - I cannot comprehend why. Am I right in assuming the Return event has something to do with a NavigationService that my Mai ...Show All

• Windows Forms User-Drawn Custom Control and Property Window / Designer-Time

  Hi. I am trying to get the property window to work with my knob control I am creating. First, I am trying to get my property window in VS2k5 to respond to my knob control. I added the public rotate property, but nothing's showing in my property window.

What can I code to get the property window to work with my control Second, I wanted to prevent a user from resizing a knob, as it doesn't seem to make sense if I have my knob set to be at fixed size.

• Windows Forms Draw PNG-image on the form

  I'm using VB.net (.Net 2.0). How to draw a png image file on the form by clicking a button I would like to set the cordinates (x, y) but the image size should be the original of the file. I would like to view the png files as transparent (as they originally are). When clicking the button set a global boolean to true (i.e LoadImage), then call Me.Refresh(). On your form event called Paint do the following Private Sub frmMaint_Paint(ByVal sender As System.Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint if (LoadImage = True) then e.Graphics.DrawImage("C:\myimage.png", New Point(100, 200)) end if End Sub Untested, should work.

• .NET Development IPermission.Union help

  Can someone help me understand what actually happens behind the scenes in the Union method on an IPermission implementation   Here's my basic scenario:  I have an custom CAS atrribute that requires up to three values to be evaluated together to know if the demand will pass or not.  This became difficult to manage when trying to determine how to union two instances of the IPermission implementation together.  So, in the Union call, I evaluate Demand on the current instance and on the target.  Those resolve to a "Yes/No" answer that are passed as two bool values to another IPermission implementation - UnionPermission.  The demand on this permission just evaluates the two passed in bool values.  However, ...Show All

• Audio and Video Development Any method for MF PVP application fail gracefully if video driver is not PVP signed?

  I am working on an application that runs protected playback with Media Foundation. I've encountered a problem that with some graphics cards, an error dialog box pops up from another process saying " Bad Image: X is either not designed to run on Windows or it contains an error". After repeatedly pressing OK for the same dialog poping up many times, I can see the application hits a debug assertion saying that  ESP is not properly restored.
