Are using SetModified() when the user changes any items in the dialog?
The code you posted is in an OnKillActive() override?
If using DDX are you calling UpdateData() where appropriate?
|

I'm am not using SetModified().
I have OnKillActive() and OnSetActive() overridden to only return TRUE to prevent the changes in the pages from being reverted by the DDX calls when switching between pages (tabs). Will SetModified(TRUE), fix this?
I'm using UpdateData() on my overridden OnOK(), since for some reason the data wasn't being updated (probably due to me not using SetModified()).
I'll try to incorporate SetModified() (which I need to do anyways) and get back with you. Having to redesign a little to accommodate the Apply functionality.

OK I've modified a few things to handle the Apply functionality, and I am using SetModified().
Everything looks good except, If I apply a change, and then click Cancel, the changes are not updated. I read that OnApply() just calls OnOK(), which calls UpdateData(TRUE), so why are my changes being reverted?
If I make a change and click OK, my changes are stored.
I'm used to Apply storing changes, regardless of clicking OK or Cancel.

Sounds like it's working like it's "supposed" to 
To save changes on cancel (not what a user would expect) you'd ned to do the same thing in
OnCancel() that you do in your OnOk() (or wherever you are committing the changes).
Instead of duplicating the code you can add a function that does all the saving and call it
from both places.

Never mind.
In the midst of restructuring the property pages, I forgot I was still updating the properties outside of the actual property page class. And plus I wasn't overriding OnOK() to update the data. 
Still don't know about the message box. Hopefully it won't bother me with the new structure.

It may have something to do with me not using SetModified()...

Hi,
I'm porting one of the dll from vc6 to vc8. In doing so I have created a complete framework to create a dll and subseqently add atl objects.
By default the framewaork adds the follwoing code in the main app file
class MyClassModule : public CAtlDllModuleT< MyClassModule>
{
public :
DECLARE_LIBID(LIBID_MyClassLib)
DECLARE_REGISTRY_APPID_RESOURCEID(IDR_MYCLASS, "{7C00C752-3DA7-4CB9-B721-7F39F9FEDD2E}")
};
In previos versions of ATL CComModule _Module was used which has been replaced by CAtlBaseModule.
Problem:
There was an extern declaration as extern CComModule _Module in stdafx.h and definition in main app file as CComModule _Module .as CComModule is known to stdafx.h all other classes could use _Module and calls its methods by including stdafx.h
How do I replicate the above behaviour in the new version?
How do I use the functionality of the class MyClassModule in other modules as this class is defined in my app file as MyClassModule but this MyClassModule is not known to stdafx.h and thus all ther classes cannot see the definition of MyClassModule.

I have a file is one of my projects which stores data and behaves as a circular buffer. Since the data need not be stored continiously in the file, I would like to enable and disable "Read only" property of the file as per the requirement.
So I have written the following code for the file.
ofstream _logs;
const char* _file = "xxx.txt"
ofstream _logs(_file, ios::out,ios::trunc)
The file properties will be handled using the APIs
SetFileAttributes(), GetfileAttributes()
Now I would like to control the data written into file externally from the file properties menu. But I when I uncheck the "Read Only" check box on the file's property menu from windows explorer, the files still behaves as Read Olny and the data does not get written into the file.
Please suggest a solution for this.

Should not be any problem with these API's.

Could there be other reason for this ? other that 'readonly' property.
Apprantly it should work.

There is a thread in my application which should write a data continiously.
As soon as the Read Only property is unchecked, a thread in my application will start writing into the buffer. I am not seeing this happen

Hi just a quick question.
How can i set the style of a ListView control to LVS_REPORT. I have searched and only found a method that doesnt work for VS2003.NET - Basically right click the control and change the sytle property. The property doesn't appear to be there.
I am sure I am missing something simple but oh well cant see the forrest for the trees.
Cheers
Dan

Its very difficult to be familiar with changed IDE, And again in this case, Its very easy to miss out.
|

In addtional you can set it with ModifyStyle
|
|
|
|
|
Also programmatically on init:
BOOL CListViewDerivedClass::PreCreateWindow(CREATESTRUCT& cs)
{
// Modify the Window class or styles here by modifying
// the CREATESTRUCT cs
//--THIS LINE HERE--
cs.style |= LVS_REPORT;
return CListView::PreCreateWindow(cs);
}

Dear All,
#import "msxml4.dll"

I'm not getting any errors. Which IDE you are using ?
Infact, I'm not getting errors on VS6 and VS8.
Can you show exact error, you are getting.
|
|
|
|

Unfortunately, what worked in VC++ 6.0, no longer works in VC++ 2003. I'm not sure what version your using but we have to resort to using the scope resolution operator when programming MSXML in VC++ 2003. 
Comment out the using namespace MSXML2[^]

Hi all,
Is it possible to use the strncpy() function to achive the following:
FileName1.txt to FileName1.abc
I have tried the following:
<code>
int ExtensionLen;
char *ExtensionString;
ExtensionString = FileNameFromClient;
ExtensionLen = strlen(ExtensionString) - 4;
char extstring[20];
strncpy( (char*)extstring, ExtensionString, ExtensionLen );
strcat((char*)extstring,(char*)".tcp");
</code>
Just to change the extension, or is there something else I could use?
Thanx

If you want to do it in plain old C, here is a way:
char fileName[20];
strcpy(fileName, "FileName1.txt");
// Now change extension to ".abc"
// "Smart" coding, assumes there is a dot in the filename
strcpy(strrchr(fileName, '.'), ".txt");
OR (safer):
char * cpDot = strrchr(fileName, '.');
if(NULL != cpDot) strcpy(cpDot, ".txt");
Let the flaming begin! (I won't answer, I have work to do).
