Sorry guys, but it's still not working. I've tried changing the message map as directed, but nothing happens. The message is still not sent. (I've checked with a messagebox.)

I noticed that the MSDN article refers to CListView while I'm working with a CListCtrl. Could this have anything to do with it?

I have to admit I don't really understand everything being explained in the thread, but no worries: it works now.

I'll just give a short report for any interested parties too lazy to check the thread you mentioned:

PROBLEM: Stop CListCtrl column headers from being resized.

SOLUTION: Let your view handle the HDN_BEGINTRACK message and have it return TRUE.

void CMyList::OnBegintrack(NMHDR* pNMHDR, LRESULT* pResult) <br />
{<br />
	HD_NOTIFY *phdn = (HD_NOTIFY *) pNMHDR;	<br />
	*pResult = TRUE;<br />
}

BUG: Something about the class wizard messing up and another thing about unicode and ansi, which results in your handler never being called.

FIX: Edit your message map manually.
First remove:

ON_NOTIFY_REFLECT(HDN_BEGINTRACK,OnBeginTrack)

And instead add:

ON_NOTIFY(HDN_BEGINTRACKW, 0, OnBegintrack)<br />
ON_NOTIFY(HDN_BEGINTRACKA, 0, OnBegintrack)

That's it. Thanks 4 the help, guys.

I am developing a password entry screen( VC++ dialog based application) I am storing password in registry in HKEY_LOCAL_MACHINE\\Software\\myapp
I want it to encrypt and make access denied.
How can we set permissions of a key or its subkey . I need that the access should be denied ,if somebody tries to delete this key the key shouldnot be deleted (ie key should be read only)
I am developing it for Windows NT/2000
Hoping for a positive response

hello to list

any assistance much appreciated.

i apologise if this message loads slowly (received a warning when i sent). i live way out back, very slow connection, and i get email longer than this no problem)

why did the one project i did compile include syntax
different to the text book example? (staugaard, jr. structured and object oriented techniques, 2nd edition)

using borland 5.5.1 free command line tools with a command promt screen setup for me be a student list advisor so i type in 'complink <filename> to compile. i don't want to bother him further on this matter. couldn't figure out how to get a project to compile with borland 4.5, but have succedded in getting one to run with 5.5.1. i thought all i would have to do is use the same #include, #endif, etc, and all would be well. i think the enum is wrecking things in some small part, i can't find any information to show me rules for using enum's in structs. this code is probably a bit cut up by now.

you may have to fix the word wrap
you may assume i am rather green at this

Something is rotten with your include-path: the compiler does not find the header file to include. He is probably not searching the Dir where it sits.

Correct that and most (any?) of the errors are fixed.

The compiler ( being supid as toast but a workaholic;) ) tries to interprete the rest of your code anyway, and fails.

My opinions may have changed, but not the fact that I am right.

I know it sounds silly, but are you sure your file is named 'Yahzt.h'? I once mistyped the filename for a class. I wanted to include the headerfile but it wasn't found. After half an hour searching for the error I checked filenames and found the problem Blush | :O

Modularity with C++ on Windows and Linux

Hi !

I am facing a problem which I don't know if a solution exists. I might have to develop a software which should fullfill these requirements :

- Modular
- Using an Oracle database
- Have to work on Windows and Linux

I know that Oracle exists for both OS. I don't exactly know how to interface it in a way that will work for both Windows and Linux.
But my main concern is regarding modularity. Each time I had to have modularity under Windows, I just used ActiveX components. I was easy and worked well.
But, how to achieve such modularity on Linux ? Is it possible to have a concept of modularity which would work for both Windows and Linux ?

Any hints, help, links, advice, etc.. will be greatly appreciated !

There is (almost) certainly no single framework for you to work with, and the resulting code compiles on Linux and Windows.
To make a GUI that works with Linux and Windows use Java, or you can try wxWindows[^]. It works fine, but is not as advanced as MFC.

ODBC interface to databases is available both on Linux and Windows. I guess Oracle has some lower-level API that might also work on both systems.
There's an implementation of DCOM for Linux from Software AG.

Where to put ddx.clw ?

Hi,

I've succeeded in writing my own DDX and DDV routines.
After implementing the ExtraDDX stuff in my project's clw file,
I now want to make these routines available to all my future
projects by putting it in ddx.clw as suggested in Technical Note 26 !
I've already tried the following directories ...

c:\program files\microsoft visual studio\common\msdev98\bin<br />
c:\program files\microsoft visual studio\vc98\bin<br />
c:\program files\microsoft visual studio\vintdev98\bin

But no success so far Frown | :-(

The content of my ddx.clw file is ...

[ExtraDDX]<br />
ExtraDDXCount=5<br />
ExtraDDX1=E;;AC Value;BYTE;0;ACText;AC BYTE with range verification;ACMinMaxByte;Mi&nimum;u;Ma&ximum;u<br />
ExtraDDX2=E;;AC Value;short;0;ACText;AC Short with range verification;ACMinMaxShort;Mi&nimum;d;Ma&ximum;d<br />
ExtraDDX3=E;;AC Value;UCOUNT;0;ACText;AC Unsigned short with range verification;ACMinMaxUshort;Mi&nimum;u;Ma&ximum;u<br />
ExtraDDX4=E;;AC Value;int;0;ACText;AC Integer with range verification;ACMinMaxInt;Mi&nimum;d;Ma&ximum;d<br />
ExtraDDX5=E;;AC Value;UINT;0;ACText;AC Unsigned integer with range verification;ACMinMaxUint;Mi&nimum;u;Ma&ximum;u

Can anyone please tell me where to put it or is it just not possible with VC++ 6.0 ?

Thanks ...Sven

I want to Create a Process with CreateProcessAsUser from as PrintMonitor running under the System Account

Hello,
I want start a application from a Portmonitor after finisch the Print of the document. Currently i start the application with createprocess but the application running under the system account and has no access to the My Files Directory and the MAPI interface and so on, only acces to the Files or Directorys with "Allow All" access rights.

I need to start the application with the rigths from the logged on user.

i have found many sample and notes with create user but i must given them a user account name and passwort with domain but i will to start the application on the desktop of the logged on user with the rights of this user. the samples i have found to do this without given of a username, password do not work.

This Portmonitor is a part of a Printerdriver you can easy print on in and it make a pdf for you to save or mail it. If the PDF System finished it will be distributed under the GPL.
The Printerdriver, Portmonitor and Application working fine but the problem with the rights under system account is open.

Thanks for help me.

Sorry for bad english.

Typically I have apps that create either registry or an ini entry. So I just detect whether this has occurred. Another way would be for your app to create or delete a dummy file in the program's own directory.
Another way would be to compare the time the app is downloaded to the time of the running. But this would be quite imprecise.
I don't think their is any API IsFirstRun() function in the system.
