c# - Menu click causes form to "lose focus" and menu dropdown disappears -

February 15, 2010

I have ContextMenuStrip or MenuStrip . I do not really know what is happening because of this, so to see any of the following, a repeat test should be prepared:

I have created two Windows Forms: Form1 and Form2 . Both have been linked to a menu strip . Both are set to StartPosition = CenterScreen .

Form 1 is a simple menu like this: Form2 & gt; Open . Clicking on "Open" will launch Form2 .

Form2 is such a simple menu: try to open & gt; Other TestMenuites

Launch the program form1
Open form2 to form1 (that is, form2 & gt; open ].
Form2 appears. Try opening form2 , menustrip at

 / Code>).  Form1  again looks at  form2 , although  form2  is still a focus (you can see it if you select  Form2  a bit

  If I for the owner of  form2  to  form1 ,  form2  Setting> When You Trying Step 4 , Then remains visible, but the menu does not appear for the first time after all the other clicks appear to be OK. 
  While trying to open a context menu (on another form opened on another form) See, and it will disappear immediately, but only for the first time. After this every time it will open normally. Do anyone have any idea what is happening?

  
  Yes, it's RTM version of .NET 4.5 Is known bug. This is mentioned: 
   When you click on a menu item to open a child window in the app, interactions with the menu and the child window behave incorrectly. For example, the following: 
 - When you open a shortcut menu in the child window, the main window takes the form focus. 
 - You can not use mnemonics to access menu items. 
 
  As you can tell from the KB article, this bug was fixed quite a while ago. Bug fixes were included in the maintenance release, which was available on January 8, 2013 for the first time. Make sure that Windows updates allow you to deploy that update on your machine. Or download it.

sockets - capturing TCP packets flow -



    Problem statement: Suppose a parent is hosted on server machine IP: 1.1.1.1 and something in that server The time is called three different servers A (1.1.1.2), B (1.1.1.3), C (1.1.1.4). They can be server database servers or other servers. Now you can send an http request to 1.1.1.1/somepage.htm from your browser, as a result some TCP packets will go to server 1.1.1.1, and 1.1.1.1 a TCP can send packets and packets, target C as well, without installing any agent software in any server, get all TCP packet information from the browser machine. One solution is that we can write a code on server machine 1.1.1.1 which will filter all TCP packets in relation to the related IP. But I do not want that solution. Is there any way to solve this issue? Is it possible to present a new protocol for this? But server codes can not be modified.      Does any agent software include anything like Verhark? The usual way to see all the datagrams obtained is by using sniffing like a wirhark or you can ...






javascript - How to set the table width to parent div width in
wordpress widget -



    I am writing a plugin for WordPress and use a table layout in the widget wrapper to display rankings and game schedules. I am doing A line with all the information given is used in approximately 1000 pix width for a widget with a width of 260px or 360px, I want to leave less important information to display the most important information in a row. Due to interchangeable themes in WordPress, I do not know how many widgets will be in WordPress.  and examples of my current theme, based on the available width, I want to display more or fewer columns to fill the row. My idea is to first set the width of the table in the inner width of the wrapping divis, that I can do this with something like    $ ('# objects'). Width ($ ('# Object') .Parent (.) Width ()); Second, it is my goal that to display some columns per line, depending on the width of the row   My questions:    Is my planned way of accomplishing this by sending the width of the table as the parameter of the javasc...






firebird2.5 - What is the use of firebird.msg in firebird database -



    I'm thinking of using Firebird with my application. I would like to know that the  firebird.msg  is used for the file. Is it an optional or compulsory file to include in your app installer package?       firebird.msg  contains firebird's actual error messages when an error occurs , Firebird only sends the error code and message parameters. The client library then sees the actual error message text in this file.   Without the presence of this file (for firebird 2.5 and earlier its in a folder for  fbclient.dll  (or similar libraries), Firebird 3 and later the same folder In) errormessage will only report that it can not get the  firebird.msg  and error number.   So you do not really need it, but if you need firebird clients or embedded libraries or want and if you want or want a meaningful error message from the firebird, then you should include it.
