• Windows Forms Position of context menu

  Hi, How can I get the position of context menu Thank's Alexei Normally, the context menu will be shown at the center of the control when the keyboard is used to invoke the context menu of a control (Shift+F10, for example). You can customize the location as follows. Override WndProc in the grid and check if the Message.Msg is WM_CONTEXTMENU (0x007b) If so, check if the Message.LParam is -1, which means this was due to a keyboard message as opposed to the user right-clicking the mouse. Now, call the associated ContextMenu's Show method explicity at the selected row position. Make sure NOT to call the base class after show ...Show All

• .NET Development Keeping Unmanaged DLL Used by P/Invoke in Memory

  I use a 3rd party DLL, written in C++, that I call via P/Invoke (C#.NET 1.1). Problem is this DLL takes about 3 times as long to call the first time it initializes that it does subsequent times. Calling it via P/Invoke seems to cause it to load everytime. How do I keep it in memory so I do not get the initialization overhead everytime I call it.   dimkaz wrote: Oh, and you might want to add SuppressUnmanagedCodeSecurityAttribute  to your pinvoke signature to avoid security checks on every invoke. Of course, you'll only want to do that if you do not expose your P/Invoke signature publicly, and you ensure that you've ...Show All

• Visual Basic Loading Data Using ProgressBar as Indicator

  Here we go again folks, hope you help me out on this one...I had a form(frmAccount) wherein it has a datagridview(dgvAccount) that bounded to a certain table of my db.Because of too many records(about 20000), it takes such time(about 8seconds almost) to load all of the data...I had no idea how can I possibly decrease this loading time so I just put a progressbar(pBar) as an indicator of the process.This progressbar was attached in the main form(frmMain)...What I really want to do is, once I clicked the button on the frmMain, pBar would automatically increment to its maximum with respect to the loading of frmAccount...Simply put, unt ...Show All

• Visual Studio Stepping through the debugger takes a life time.

  Hi all, I have just gone through the process of upgrading to VS 2005 from VS 2003 and have noticed that when I debug my application stepping through it takes an absolute age now. It takes around 12-15 seconds for each step - making my debugging life hell :( Are there any ways I can look in to actually speeding this up Thanks Tryst Are you running into this http://blogs.msdn.com/greggm/archive/2005/11/18/494648.aspx ...Show All

• .NET Development Remoting between 1.1 and 2.0 - Index outside bounds of array!

  Hi We have a system written in .net v1.1. We have converted the ASP.NET interface to 2.0 ( not beta 2 , but the version that was released with the release candidate of Visual Studios 2005) The Data Access Layer is a .net v1.1 project containing a  number of MarshallByObjectRef classes running as a Windows Service. Now when the ASP.NET interface attempts to invoke a method in one of these classes we get the following error, (though we can successfully create an instance of these objects): System.IndexOutOfRangeException: Index was outside the bounds of the array.    at System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMess ...Show All

• Visual Studio Tools for Office A newbie question: how to control word directly?

  VSTO provides a document-centric way, but sometimes I just want to control the Word directly and do some simple task, e.g. launch the word, ask it to open a .doc file, insert some text into that doc file, and save that doc file into some location on my disk. I don't want to generate some class object in my program, just want to direct the word to do something. Can I do this in VSTO Thanks! Hi, With VSTO 2005 you can only create document based solutions. With VSTO v3 you will be able to create VSTO application level add-ins with Office 2007. But for now you must create a standard COM add-in using Visual Studio. Paul Stubbs ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA needs visual studio 2005?

  I am working with Dark Basic Professional and want to check out XNA. I have visual studio.net I can't find if XNA will work with VS.NET or if I will be forced to upgrade to VS 2005.  Knowing Microsoft they will use XNA to drive sales of every new version of visual studio that gets released. So will XNA work with visual studio.net Sorry if I sound bitter about all the new version of visual C. I don't have a lot of money and I keep hitting roadblocks. Are you speaking of XNA Build or the framework XNA Build will install the Visual Studio IDE so you don't need to purchase any Visual Studio product for it to work. We don't have any pl ...Show All

• Windows Forms Grid column-styles widths not applied (see style code)

  I have a not-strongly-typed VB. NET 2003 dataset and one table displayed in a datagrid using a dataview. The display is entirely proper prior to applying a style. Applying a style (code below) results in very small column widths, with everything scrunched to the left. Expanding the columns using the cursor shows that all other style directives have been applied; just column widths have not been applied. Here’s the style code: Private Sub gridstyle() ' Set the styles of the columns of the grid. Dim dgY1 As New DataGridTableStyle dgY1.GridLineColor = System.Drawing.Color.Green ...Show All

• Smart Device Development SD Card Question- URGENT!!! New Question

  When using a SD card for data storage does .net cache the data and write it later or does it write as used   I am losing data and have no reason for this to happen.  It is as though the user never wrote to the SD card.  I had a user bring in his device.  I looked at the screen that displayed his orders.  They were there...clear as day..., orders 1-4.  This meant that the user had saved 4 orders.  As each order is saved, there is a file that contains a single record.  This record is the order number and it is updated each time an order is saved.  This would have been order number 4 in that file. ...Show All
