• Smart Device Development Exposing .NET Compact Framework Components to COM

  Is there any tutorial out there for the following Exposing Managed Components You can provide managed .NET Compact Framework components to native applications . The process involves the following tasks: Design your managed types while considering COM programming. For example, do not use generic types. Define the functionality you wish to expose in a managed interface , and have your managed object implement this interface. The following is recommended: Use the GUID, InterfaceType, and ComVisible attributes for your managed interface. Use the ClassInterface(ClassInterfaceType.None) attribute on your managed object. Create native definitions of your managed types. Pass your managed ...Show All

• Visual Basic Dataview table problem

  I made a form and put a datagridview table in the form.

Can this be set elsewhere other than code Or can you help me with where it goe ...Show All

• Visual C++ Pressing 'Enter' key terminates the Application.

  Hello! I had asked for the solution of this question earlier as well,but, those solutions did not work. I was asked to look for 'OnOK()' and override it. But the biggest problem is that even after overriding it , the debugger doesn't doent stop at this function. hence proving that 'OnOK()' solution doesnt work here. Please suggest me the solution to this problem, as, this is the last thing that is blocking the completion of this project. What do you mean by "the debugger doesn't stop at this function" The application quits as you hit enter, when launched through the debugger If that's the case, you haven't overridden OnOK in the correct class. Can you make a completely fresh project, override the function, confirm that i ...Show All

• Smart Device Development Battery indicator on ToolBar? How to?

  I got a requirement to place a battery indicator on the ToolBar of a .NET CF 2.0 form on Pocket PC 2003. I started by assuming that I could derive a custom control from ToolBar, and modify OnPaint to add my indicator. But to my surprise, OnPaint is in fact never called. The designer of the System.Windows.Forms.ToolBar must have gone to great lengths to hide/disable/avoid all the functionality inherited from the Control class. For example CreateGraphics is not supported ! I now have a working method using PInvoke GDI that looks OK, but feels somewhat like a HACK. What is the "correct" way to do it. I will "reveal" my code later. What would that accomplish, except filling the pr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Microphone input

  Hi, is there _any_ way to get input (16bit PCM would be perfect) from a microphone connected to the XBOX360 I'm planning to write a karaoke game (like SingStar), but that's not really possible without microphone input support. I already have code to analyze input streams and everything that I need, the only thing which is missing is a way to get input from microphones. Any ideas Patrick What a shame! It would be a great feature to build great rich-media games. As SingStar is very popular on Sony's Playstation, a game like this would be a great addition to the choice of XBOX 360 games. ...Show All

• .NET Development Save SQL dataset to Access database

  I have a dataset populated with data I've queried from a SQL Server database. I have an access database file with exactly the same tables as the SQL Server database. I know how to connect to the access DB, and create a data adapter, etc., but am unsure as to how to add the data from the dataset generated from SQL Server and save it into the access database.

• SQL Server Fuzzy Grouping seemingly corrupting data

  I've seen one other post on this topic from October 2005 and I thought I'd bring it up again. I've a Fuzzy Grouping component in my data flow. The output data from it appears to be the result of records spliced into other records. This includes pass-through columns, not merely "clean" or similarity columns. For example (I've added the suffixes for illustrative purposes): AddressLine1_in: 162 OAKMONT AddressLine1_out: 162 OAKMONTLAMINATION INC CityStateZip_in: Alexander, AR 72002-8539 CityStateZip_out: Alexander, AR 72002-8539116-7066 These are just pass-through columns, although "used" columns are seeing something similar (below.)

• Visual Basic convert datagridviewtextcolumn to strings(window applications)

  Using VB2005 Can anyone help me with this How to convert the datagridviewtextcolumn to strings You simply want to refer to the value property of the specific row and cell. The datagridview rows and cells are simply collections you can use, the property will get the contents of the cell - in this case column1 is a cell of type datagridviewtextcolumn. dim s as string = me.Datagridview1.rows(0).cells("Column1").Value If you want to change the value to other types then you may need to cast the value with ctype.

• SQL Server Cannot open database

  My mdf file was deleted. I was able to restore the said file but unfortunately I can no longer open it. I have also noticed that the recovered mdf file was smaller than the file before it was deleted. What can I do to open the database file I have tried the following lines using osql utility. 1> use db1sql1 2> go Msg 946, Level 14, State 1, Server JDI11-31, Line 1 Cannot open database 'db1sql1' version 525.

This means that no SQL Server tools can connect to the database. Your only recourse in this case is to restore from a b ...Show All
