Hi
To associate a file extension to your program, you should create a registry entry under
HKEY_CURRENT_USER
-->Software
-->Microsoft
-->Windows
-->CurrentVersion
-->Explorer
-->FileExts.
1. Under FileExts create a key with same name as your file extension.
(Eg: For bitmap files you can find a key named .bmp under FileExts.)
2. Also create a subkey named "OpenWithlist".
3. Add a string value named "a".
4. Set the value data of this key as your application path.
(Eg: for paint you can find the entry mspaint.exe as value data)

Hi
Sorry i made a mistake.
1. Under the FileExt key, add a string value named "Application".
2. Set the value data of this string value as your application path.
(Eg. For .bmp you can see this value as mspaint.exe)

Hello,
I've got a tree control on my dialog with checkboxes. Everything works fine, except that I cannot find a proper way to check wheter the checkbox is checked or not  .
It's probably a simple tiny thing, but I can't find it! Does anybody know what I have overlooked?
Thanks in advance.

If you are using MFC use this:
BOOL CTreeCtrl::GetCheck( HTREEITEM hItem ) const;
If you are using Win32 API, you have to send a message:
TVITEM item;
item.mask = TVIF_HANDLE | TVIF_STATE;
item.hItem = hItem;
item.stateMask = TVIS_STATEIMAGEMASK;
::SendMessage(m_hWnd, TVM_GETITEM, 0, (LPARAM)&item);
bChecked = (BOOL)(item.state >> 12) -1;
Hope that helps

Hi
DeleteFile(lpFileName)
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.

I'm trying to make a program just like notepad but a little bit more "Funner". I have nothing right now on my spare time to do so don't ask. I can't seem to find a function to clear the recent file list when you click the 'File' in the menu. Can anyone help me??

The MRU list is a CRecentFileList member of the CWinApp object. It has a Remove() method.

This is my first OCX control. I managed to "hack" through using an example and can Get/Set the stock properties through a "wrapper class", however, I am having trouble adding one of my own custon properties. I am using VC++ 7.0.
Wrapper Class:
//--------------------------------------------------------------------------------.cpp
void CWrap::m_vSetParams(int nPtSize)
{
// I am able to get nPtSize!
return;
}
//---------------------------------------------------------------------------------.h
---
void m_vSetParams(int, CString);
---
OCX Control Class
//--------------------------------------------------------------------------------.cpp
//DISPATCH MAP
---
DISP_PROPERTY_EX(CGrpBoxExCtrl, "PointSize", GetPtSize, SetPtSize, VT_I2)
--
//DISPATCH MAP
void MyOCXCtrl::SetPtSize(short nPtSize)
{
m_nPtSize = nPtSize;
return;
}
BSTR MyOCX::GetPtSize()
{
return ........
}
//---------------------------------------------------------------------------------.h
short m_nPtSize;
---
public:
enum {};
afx_msg void SetPtSize(int);
afx_msg short GetPtSize();
---
//---------------------------------------------------------------------------------.odl
Totally Lost Here!
//---------------------------------------------------------------------------- Question
How do I get the information (nPtSize) from the "wrapper" class to the control. Could
someone please fill in the above or direct me to a simple artical or sample that would guide
me.
Is there a Wizard that does this, and if so, where in the Visual Studio editor is it?
Need I point out that MSDN is totally & hopelessly confusing?

Hi
I´m new to C++ and working with passing files back and fourth to a
webservice. I have found som code in C# that does this for me but I can´t
convert it into C++. Can someone please help me with the two last lines?
DimeAttachment attachment = new DimeAttachment("application/octet-stream",
TypeFormatEnum.MediaType, ms);
HttpSoapContext.ResponseContext.Attachments.Clear();
HttpSoapContext.ResponseContext.Attachments.Add(attachment);
I keep on getting the error C2512
...
HttpSoapContext *hsc;
hsc = new HttpSoapContext;
...
is not possible
Regards

The HttpSoapContext class needs a default constructor. Can you show us the class declaration?
|
|
|
|
|
Hi
Thank you for the answer, the class declaration goes as follows.
*******************************
HttpSoapContext Class
HttpSoapContext Members | Microsoft.Web.Services Namespace
Requirements
Namespace: Microsoft.Web.Services
Platforms: Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
Assembly: Microsoft.Web.Services (in Microsoft.Web.Services.dll)
Provides access to the SoapContext associated with a SOAP request and SOAP response for XML Web services created using ASP.NET. This class cannot be inherited.
For a list of all members of this type, see HttpSoapContext Members.
System.Object
Microsoft.Web.Services.HttpSoapContext
[C++]
public __gc __sealed class HttpSoapContext
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Remarks
The SoapContext provides access to the WS-Security, WS-Routing, and other XML Web services architecture-specific details associated with a SOAP message.
Use this class to gain access from within an XML Web service to the the SoapContext associated with a SOAP request through the static members RequestContext and ResponseContext.When an XML Web service method is a one-way method, an XML Web service cannot gain access to the SoapContext using the static members of this class. To gain access to the SoapContext for one-way methods, the class implementing the XML Web service should inherit from System.Web.Services.WebService and add code within the one-way method to get the Context property.
Requirements
Namespace: Microsoft.Web.Services
Platforms: Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
Assembly: Microsoft.Web.Services (in Microsoft.Web.Services.dll)
********************************

This is the class documentation, not the declaration. A class's declaration is usually kept in a .H file.
|
|
|
|
|
Hi
Hmm.. I can´t find the declaration on my computer, is it possible? It´s under the namespace Microsoft.Web.Services imported from the dll with the same name.
How do I proceed?

Oh well. I just wanted to see the available constructors. Is HttpSoapContext a C# thing?
|
|
|
|
|
I guess so, but it has a "C++ definition" since
[Visual Basic]
NotInheritable Public Class HttpSoapContext
[C#]
public sealed class HttpSoapContext
[C++]
public __gc __sealed class HttpSoapContext
[JScript]
public class HttpSoapContext
... hence it should be supported in c++ also.
Is there a problem that the class is sealed? I haven´t had any problem with other conversions from C# into C++ when I have worked with web services.
Regards
Daniel

It just means that it can't be a base class. Other than that, I do not know.
Regardless, it sounds like you need to supply some parameters during construction of the object.

For starters, it should say
hsc = new HttpSoapContext();
Other than that, HttpSoapContext obviously needs something passed into it's constructor, there's no constructor that takes no parameters. You may or may not have worked that out from the prior response. The other possibility is that HttpSoapContext is a class in the .NET framework, unless you're using Managed C++, there is no guarentee this class even *exists* in the C++ framework you're using.
