• Visual C++ where the vtable memory will be sotred?

  hello , where the vtable memory will be created . Virtual functions callings are resolved at runtime . but when i write the class which has a virtual functions iam getting the size of the class = data + vptr but where the vtable memory is stored When you make any function virtual, the compiler will insert a vptr inside your class. As a result, the size of the class will grow by 4 bytes (on Win32).This pointer holds the address of the virtual table (vtable). vtable is constructed by the compiler at compile time and is basically nothing but an array of function pointers. The function pointers are actually pointers to the virtual functions of that particular class. To be more exact, the vi ...Show All

• Visual C# Visual Studio 2003.NET bug -- can't embed resource *.cs.dll

  Not sure if this is the best place to report bugs, but I'll give it a shot. I was recently implementing a C# tool that talks to Adobe Photoshop through a COM interface. I decided to embed the COM interop assembly as an embedded resource, and because I'm working with Photoshop CS and CS2, I decided to rename "Interop.Photoshop.dll" to "Interop.Photoshop.CS.dll". This was working fine for my "Interop.Photoshop.CS2.dll" file, but for some reason the CS version wasn't working. Turns out you can't embed resources whose filenames end in ".cs.dll" -- they silently disappear into never-never land and will not show up through Assembly.GetManifestResourceNames. What's more, other embedded resources may also ...Show All

• Community Chat What version of vista are YOU getting?

  So, out of all of the editions, Home Basic, Home Premium, Business, Enterprise, Starter and Ultimate , which are you getting I am going to get Home Premium because it seems like it has mostly everything I would need.

• Visual C++ SetCheckboxValue method

  Hi, When i try the SetCheckboxValue method i get a compile error saying identifier not found... This is the actual code i get the error at: SetCheckboxValue(IDC_mycheck, true ); Any ideas Cheers Anger. Hi. I think that you use an Interface "ICredentialProviderCredential::SetCheckboxValue Method" for Set checkBox; that exists in WinSDK. http://msdn.microsoft.com/library/default.asp url=/library/en-us/shellcc/platform/shell/reference/ifaces/icredentialprovidercredential/setcheckboxvalue.asp for use this Interface you must initialize a COM.  like this : #include "Windows.h" #include "wininet.h" #include "shlobj.h" using namespace std; int main() {  HRESULT hr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Do most SDKs do grapics, such as 3D?

  As far as Managed Direct X, and Visual C# Studio Express,with XNA, do those have a way of creating the actual graphical interface for the game, such as 2D or 3D, or do I need Adobe Photoshop, or Maya, or some other program I currently havn't been able to download them because I am temporarily on dial-up internet, which also makes me not want to do too much looking aroudn, due to long loading times. Thanks for any help you can give me. Paint shop pro is dirt cheap because it keeps changing owners, but it does 90% of what ps does and more stuff ps does not, only the work flow is very different for some things and bevels and such still are not where they need to be.

• Visual Basic Programming Languages

  Hi, I'm relatively new to programming, and Visual Basic doesn't seem to be that good of a language, and not that much used in real applications. I want to move onto a different language, one that is very popular, can do almost anything, and can be and IS used in professional applications. Another important factor is platform compatibility. Java provides that, but Java isn't that popular for Windows, and Windows is my primary target. C++ works, but I have a couple of questions: 1) Can C++ be used on any OS Is it a good language to use as my primary language 2) Is C# going to replace C++ Does that work on other OS's C# is newer, and so I'm thinking maybe its the new version of C++ that's going to replace it, as xhtml is probably going to do ...Show All

• .NET Development DllImport Issue

  I am currently trying to make use of a .dll file that was written in C++ in one of my vb.net 2005 applications. Initially I thought I could simply add the file as a Reference to my project, however, I found this didn't work because the .dll was not written with managed code. After a little research I found I could accomplish this task by using DllImport. I wrote the following code to test this: Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim InputRecords As New ArrayList Dim CmpltCheckFlag As Char Dim OutputRecords As New ArrayList Dim MessageRecords As New ArrayList Dim ReleaseList As New ArrayList CmpltCheckFlag = &q ...Show All

• .NET Development SOAP elements in reverse order of WSDL

  I am adding a web reference to a visual studio 2005 project which returns the WSDL below.  When I invoke the webservice the actual SOAP message that is created has the sequence of the firstname element and last name element in the wrong order (see attached SOAP message).  I haven't seen anything that would allow me to change the order which is required as the web service is expecting it in the correct sequence.
