• Windows Forms Visual Inheritance

  Dears, I created a base form containing few ToolStripButton and panels, but another (mdi)child form can't show all these controls after inheriting the base form. Is there any properties need to defined first, or Bring To Front (I can view it successfully in Designer Mode of VS2005, but not in runtime... :( Thanks, One thing you need to take into account is that your derived class needs access to the fields in the base class in order to change the properties. So at design time in your base class you need look for the 'Modifiers' property and change it to 'Protected'. Do this for each control/component you wan ...Show All

• .NET Development Unable to import namespace; the notorious bug - is it not fixed in .Net 2.0

  The problem discussed in the below link'd article still seems to persist in .Net Framework 2.0. Has anybody else encountered this as well Any practical suggestions Apart from "you can modify all the .xsd and .wsdl files just to get them reverted in the next accidental "update web references" right-click. http://support.microsoft.com/default.aspx scid=kb;en-us;820122 With 1.1, you had to obtain a patch from support (not downloadable). But since I've moved EVERYTHING TO .NET 2.0 now is not such a good time to say "ooops, tharr she blows ..."

• SQL Server Execution of Package failed

  I am trying to design package which would copy all tables and stored procedures from one server to another. It used to be simple task in SQL 2000, there was wizard. However the new wizard does not work... I wrote SSIS package, but when I execute I get the following error: "Can not apply value null to property Login..." Any idea It seems to me that this new SQl2005 is not that simple to use like 2000. 2000 was a great product. I am considering to rollback to 2000. Very frustrated with the new one...          There should be more to the error message than that. Please can you copy the ...Show All

• SQL Server XQuery/XPath and element substition

  Does anyone know how XQuery/XPath would work with element substition For example, if a schema had a /customer/name element, and a substitution of /kunde/navn, would looking for /customer/name find documents with either of /customer/name or kunde/navn e.g. schema fragment: <xs:element name="name" type="xs:string"/> <xs:element name="navn" substitutionGroup="name"/> <xs:complexType name="custinfo">   <xs:sequence>     <xs:element ref="name"/>   </xs:sequence> </xs:complexType><xs:element name="customer" type="custinfo"/> <xs:element name="kunde" substitutionGroup="c ...Show All

• Visual C++ read struct from file

  this is a beginner programmer questions, at least i think so. CFile::Read( void* lpBuf ,UINT nCount) i can pass a struct (first param) and the length of that struct (second param) and then i will have a populated struct. How can i do the same thing with a managed c++ function The size of an int is 2, size of a double is 8, and a long is 4, how can i adjust my struct that i am reading in to account for this offset You can just use CFile in managed C++, although I would suggest you should use fstreams instead. I would be more inclined to write the different parts of the struct explicitly though, ...Show All

• Visual C++ VC++ Express 2005 Intellisense and preprocessor Issue

  I have converted a VC++ 6.0 workspace with 3 projects to Express 2005.  In general, it is working well.  All three projects share some code files and use preprocessor macros to enable/disable some code sections.  It all compiles and works fine in both versions of VC++.  What I noticed is that that intellisense seems to be confused (or I just don't know how to set it up) as to which macro definitions are active.  I set one project to be "Startup Project" (I assume this is the closest thing to the active project in VC++ 6) but the code is colored (active/inactive preprocessor segments) based on the firs ...Show All

• Visual Studio 2008 (Pre-release) ListView selection

  Whatis the correct way to handle selection in a ListView I could add a MouseDoubleClick eventhandler, but this is not called on keyboard selection (pressing enter) Best regards, Thomas Andersen I think you can make your ListView's ItemContainerStyle use a ToggleButton as its root element. You'd obviously also need to style it to suit your needs. Then you just let all the behavioral aspects of ToggleButton that have already been provided for you by Microsoft do the work. ;) HTH, Drew ...Show All

• Visual C++ Using MFC with Windows Forms

  Hi everyone-- So this may be a silly question, excuse me because I'm very new to VC++.. The essentiality of this question is this: I'm using MS VS 2005 Standard Ed. When I create a new Windows Forms Application, and try to include afxwin.h, the program will compile just fine, but when I try to run it, it gives me a debug library error: Debug Assertion Failed! Program: ... File: dbgheap.c Line: 1414 Expression: _CrtIsValidHeapPointer(pUserData) . The reason I would want to do this is that I'm trying to create the User Interface for a program, but the base libraries I'm leveraging were originally written in VS6.0 and use MFC, and yell at the r ...Show All

• Windows Forms Resizing Control

  In C++ MFC there is a CRectTracker class that encapsulates the functionality usually associated with resizing objects.  You hold your mouse down and drag, a dotted rectangle is drawn and stretched as you do, along with handles on each side and corner.  Similar to that provided by Visual Studio when placing controls on a form. My question is: Is there any similar functionality built-in to .NET 2.0   C# specifically Rob. ...Show All

• Visual Basic Sockets... HEEEELLPPP! :)

  Hi, everybody. I'm busy porting over a Telnet server application from VB6 to VB.net. But I've hit two MAJOR hurdles. The first thing I noticed with VB.net is that there is no Winsock control. Damn. So now I've got to use the System.Net.Sockets. OK. But I also need to use Threading apparently. I've found this one hell of a learning curve and was just wondering if somebody could post an example of a simple TCP/IP server that listens on a port, accepts multiple connections and sends a message to each user that connects. Once I've gotten past this stage, my .net blues are over and I can start using the new features! Cheers, everybody Will ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. SampleFramework Camera

  I have a small problem with the sampleframework. I just create a world with one mesh and manipulate the view with the mouse / keyboard. Most works well, i.e. key movements, mouse wheel and the camera-movement with the right mousebutton. The problem is, that I can't move the world with the left mouse button. In onFrameMove there is the following code: camera.framemove(elapsedTime) device.transform.projection = camera.projectionmatrix device.transform.view= camera.viewmatrix device.transform.world = camera.worldmatrix What am I missing Nothing, thats sufficient code.
