You can find the answer somewhere in this forum.
There was some example-code in a thread in the last few days.
Search the Topics and Replies, then you'll find the code

I want to retrieve icon like "my documents" in explorer but ...
My init function:
CShellUtil::CShellUtil()
{
SHFILEINFO shFinfo;
HIMAGELIST hImgList = NULL;
LPITEMIDLIST itemlist = 0;
bError=FALSE;
if (SHGetSpecialFolderLocation(0,
SIDL_DESKTOP , &itemlist) == NOERROR)
{
hImgList = (HIMAGELIST)SHGetFileInfo((LPCTSTR)
itemlist, 0, &shFinfo,
sizeof(shFinfo ),
SHGFI_SYSICONINDEX |
SHGFI_PIDL |
SHGFI_SMALLICON );
if(!hImgList)
{
bError=TRUE;
return;
}
m_SysImgList.m_hImageList=hImgList;
}
else
{
bError=TRUE;
return;
}
Function to display icon into Tree
HTREEITEM CShellUtil::AddSpecialItem(HTREEITEM hParent, int nFolder)
{
SHFILEINFO shFinfo;
int iIcon;
BOOL bIsCDROM=FALSE;
HTREEITEM hItem;
LPITEMIDLIST pIDL;
LPMALLOC pMem;
if(SHGetSpecialFolderLocation(NULL, nFolder, &pIDL) == NOERROR)
{
if(SHGetFileInfo((LPCTSTR)pIDL, 0, &shFinfo, sizeof(shFinfo),
SHGFI_DISPLAYNAME | SHGFI_PIDL |
SHGFI_ICON | SHGFI_SMALLICON))
{
if(SHGetMalloc(&pMem)==NOERROR)
{
pMem->Free(pIDL);
pMem->Release();
}
}
}
Icon = shFinfo.iIcon;
hItem=m_TreeCtrl.InsertItem(_T("Test"), iIcon, iIcon, hParent);
return hItem;
}
When i call 'AddSpecialItem', it's OK to insert special folder
from "CSIDL_DESKTOP" to "CSIDL_STARTMENU" and
from "CSIDL_DESKTOPDIRECTORY" to "CSIDL_LOCAL_APPDATA"-> DislplayName and Icon are OK
But there is a problem from "CSIDL_MYDOCUMENTS" to "CSIDL_MYVIDEO"
No icon and no display name and SHGetSpecialFolderLocation(..) return an error
I try with
if(SHGetFolderLocation(NULL, nFolder, NULL, 0, &pIDL) == S_OK)
but no success (return E_INVALIDARG)
I use lib from microsoft SDK august 2001 on win2000 Sp2 plateform with visual sp5
Please help

Hi
I want to write some short options directly into my executable. They should be appended at the end
of the exe (comparable to the ID3tag in MP3files).
I know how to open files in binary and write/read to/from them.
My question:
Is it possible to write the information into my executable while it is running?
Or do I need to temporarily create a copy, write it into this file and then delete original file?
thanks in advance

You want to write data directly into your executable?! Really? Since MP3 files are data files, it's up to the program that uses them to define where the data goes. But I don't think you can guarantee you'll know where your compiler will put its binary data without delving into the details of the PE format.
I would suggest you create a binary resource in your executable that just contains the options you need. You can then load the values using the standard LoadResource calls.
When you need to update the resource, you can use the BeginUpdateResource, UpdateResource and EndUpdateResource functions to do so, without having to worry about copying and deleting your executable.

I HAVE done this before, a long time ago and remember having no end of problems with it, although at this point I would have to dig out the program to say exactly what they were. At this point in time, I would say it's a probably a very bad idea, and almost certainly unnecessary. (When I did it I was writing for the DOS platform, and we didn't have binary resources.)
Quite frankly doing anything with a running executable anymore is just asking for trouble. I have yet to find a "nice" way to delete a running executable from within it, let along anything more complex (Yes, I've seen numerous solutions to this problem, but they all smack of "dirty hacks" to me."
Assuming you're programming for Windows, resources ARE probably your best bet.
As far as binary resources go, I use a CFile derived wrapper class which encapsulates the Win32 resource handling calls and makes the resource(s) look just like disk files. Mine came out of a commercial code library (Dundas Ultimate Toolbox) but Code Project or Code Guru might have something similar (it's worth a look).
Probably not much help, but there it is...

You have some options, that depends of wich technology you want to use.
For example you can use DAO, for that you have the CDAODatabase, CDAORecordset, etc, classes. You can use CDatabase Class usin ODBC, or you can use ADO, or OLE DB, for those you can find a lot of article in this site....
Good Luck!!!

hello !
when i try to debug my application, the following message appear to the
output window :
`First-chance exception in Democreator.exe (GDI32.DLL): 0xC0000005: Access Violation`
What does it mean ?
Thanks.

First and Second Chance Exception Handling <br />
<br />
Microsoft Win32 Application Programming Interface (API) included with: <br />
<br />
<br />
- Microsoft Windows NT versions 3.1, 3.5, and 3.51<br />
- Microsoft Windows 95 version 4.0<br />
<br />
<br />
Structured exception handling (SEH) takes a little getting used to, particularly when debugging. It is common practice to use SEH as a signaling mechanism. Some application programming interfaces (APIs) register an exception handler in anticipation of a failure condition that is expected to occur in a lower layer. When the exception occurs, the handler may correct or ignore the condition rather than allowing a failure to propagate up through intervening layers. This is very handy in complex environments such as networks where partial failures are expected and it is not desirable to fail an entire operation simply because one of several optional parts failed. In this case, the exception can be handled so that the application is not aware that an exception has occurred. <br />
<br />
However, if the application is being debugged, it is important to realize that the debugger will see all exceptions before the program does. This is the distinction between the first and second chance exception. The debugger gets the "first chance," hence the name. If the debugger continues the exception unhandled, the program will see the exception as usual. If the program does not handle the exception, the debugger will see it again (the "second chance"). In this latter case, the program normally would have crashed had the debugger not been present. <br />
<br />
If you do not want to see the first chance exception in the debugger, then disable the feature. Otherwise, during execution, when the debugger gets the first chance, continue the exception unhandled and allow the program to handle the exception as usual. Check the documentation for the debugger that you are using for descriptions of the commands to be used. <br />
Cheers!!!
Carlos Antollini.

Its a M$ known problem, It only Occurs in Win95 or Win98 - Best thing is to ignore it, as long as its not crashing your APP

Perhaps you should read the article above. It is not limited to Win9x.
Also, it is MS, or Microsoft not M$

I have a dialog which I have set as a tool window so it is always on top. Within this window I want to dynamically load buttons each with a different bitmap on. Someone has suggested that I use CreateWindow and pass a flag to say it will be of style BUTTON so I use the following code
CreateWindow("BUTTON",
"sample",
BS_BITMAP,
5,
5,
100,
100,
m_hWnd,
NULL,
NULL,
NULL);
I'm assuming that m_hWnd member variable should be a handle to the dialog box when it is shown, but when tested comes through as NULL and nothing is shown in the dialog box. What am I doing wrong?
Thanks for any help in advance
Nick

you must call ShowWindow() function after CreateWindow().
F.Julien

|

thanks, but do I put those in the constructor of the containing dialog because obviously the buttons will be part of this. When doing this I get an assertion error, I think its talking about a NULL handle to this dialog which I thought would be a problem.
Nick

Don't call CreateWindow on the buttons in the dialog's constructor - the dialog window won't be created yet so you can't use it as a parent window. Call CreateWindow in CYourDialog::OnCreate() (if you use MFC) or in response to the WM_CREATE msg (if non-MFC) instead. Since it's a dialog you can also put the calls in OnInitDialog/WM_INITDIALOG instead.
Cheers

thanks a lot, that worked fine

You need to call to ShowWindow Function, but you are missing same values in the style parameter like WS_CHILD | WS_VISIBLE whit this last parameter don't you need to call to ShowWindow function.
Cheers
Carlos Antollini.

Button style should contain WS_CHILD and WS_VISIBLE:
CreateWindow("BUTTON",
"sample",
WS_CHILD | WS_VISIBLE | BS_BITMAP,
5,
5,
100,
100,
m_hWnd,
NULL,
NULL,
NULL);
You should also pass a child window id after m_hWnd.

How do I get this child window ID?
So far I have the following code:
CreateWindow( "BUTTON",
"sample",
WS_CHILD | WS_VISIBLE | BS_BITMAP,
5,
5,
20,
20,
m_hWnd,
/*the child window ID will go here*/,
NULL,
NULL);
HBITMAP hBmp = (HBITMAP)::LoadImage(AfxGetInstanceHandle(), "c:\\1.bmp", IMAGE_BITMAP, 16, 16, LR_LOADFROMFILE);
::SendMessage((HWND)hButton, BM_SETIMAGE, (WPARAM)IMAGE_BITMAP, (LPARAM)hBmp);
Thanks for the help so far
