Always init your tree and list ctrl structures to zero. You'd be surprised what breaks without doing this step.

TV_INSERTSTRUCT tv_is = {0};

I'm pretty sure that you need to run in ring 0 which means you write a device driver or similar kernel-mode code.

http://www.codeproject.com/useritems/interrupthook.asp[^] is for raw interrupt hooking, and to setup an interrupt handler, you'll need to use the kernel-mode api IoConnectInterrupt!

lvm_sortitems with no MFC?

Kayembi5-Sep-03 8:28

Hi,

I have a custom listbox set up with several columns (file name, file type, size and path), and I want it so that whenever a user clicks on a column header, the items are sorted, just as in Windows Explorer, for instance.

The column click part is easy, as I just have this code underneath case WM_NOTIFY:

<br />
case IDC_LIST1:<br />
	//CHECK FOR COLUMN CLICK:<br />
	if(((LPNMHDR)lParam)->code == LVN_COLUMNCLICK)<br />
	{<br />
		if(((LPNMLISTVIEW)lParam)->iSubItem == 0)<br />
		{<br />
			//need to sort items using LVM_SORTITEMS here...<br />
		}<br />
	}<br />

However, I have no idea about how to use LVM_SORTITEMS. Obviously, I need to send it using SendDlgItemMessage and use a callback function as it says over on MSDN, but I don't know how to set up the callback function.

The problem is that all of the examples I have found are MFC based, but I am _not_ using MFC, just the straight Windows API.

Does anybody know where I can find a decent "sort listview items" code example that does not use MFC, or could anybody give me some pointers on how to go about it myself?

Many thanks for any help,
KB

It has the following signature:

int CALLBACK CompareFunc(LPARAM lParam1, LPARAM lParam2, LPARAM lParamSort);

The MSDN article Q170884 should give you some ideas, even though it's in VB.

Basically, each item that is added to the list control has an associated item data (use the LVM_SETITEM message for this). When CompareFunc() is called, lParam1 points to one item's data and lParam2 points to another item's data. You have to cast lParam1 and lParam2 to the appropriate type, and then do some sort of comparision.

Hello

Does anyone know how to print HTML files from a console application? I wanna print the files like the I Explorer shows them not the source code . I think a solution could be using IWebBwoser control but i don't know how to embed it to a console application

Thanks a lot

You could write a simple web resource provider[^] to download the page to disk, then just print the file by doing:

// Print file
CString strPrintFile = "MyFile.htm";
SHELLEXECUTEINFO  seInfo;
::ZeroMemory (&seInfo, sizeof (seInfo));
seInfo.cbSize = sizeof (seInfo);
seInfo.fMask = SEE_MASK_FLAG_DDEWAIT;
seInfo.hwnd = GetSafeHwnd();
seInfo.lpVerb = "print";
seInfo.lpFile = strPrintFile.GetBuffer(0);
seInfo.lpDirectory = "";
seInfo.nShow = SW_SHOWNORMAL;
BOOL  bStatus = ::ShellExecuteEx (&seInfo);
strPrintFile.ReleaseBuffer();

// Warn user on error
if (!bStatus) {
    CString strMessage;
    strMessage.Format (IDS_CantPrintFile, strPrintFile.GetBuffer(0));
    strPrintFile.ReleaseBuffer();
    AfxMessageBox (strMessage);
}

tell CDocument not to save

I create a new document in my doc/view app, and when I close it asks if I want to save it. How do I keep it from asking me this?

I have tried SetModifiedFlag(FALSE) and that isn't working. Any other ideas?

Yes, but where are you doing this, and what code, even MFC, is setting it back to TRUE? If you do anything at all to your document, its dirty flag will be set to TRUE. Set a breakpoint in SetModifiedFlag(). Once there, check the call stack.

I figured it out.

I'm overriding SaveModified now and it seems to be OK.

thanks

Overriding BOOL CDocument::CanCloseFrame(CFrameWnd *pFrame) could also do the trick.

OCX question

Hi,

I am using an activex in my application and when I ran it on another machine it crashed because the OCX file was missing.

I add the OCX file but it still does not work....
Is there some kind of "registration I have to do"

I am using the MSFlexGrid and I copied the MSFLXGRD.OCX file (Machines that has this file are OK)

Is it possible I need more than one file ?

All COM servers (ActiveX) need to be registered. You can use the regsvr32.exe utility to register .OCX files.

stl map bug

I have an object that has a std::map member variable. I placed this object in a static library. Whenever I call the find method of the std::map I get an access violation (due to a variable pointer to uninitialized memory in the comparator).

I looked around on the internet and found out that this actually is a bug in the xtree header file (see here[^]). Does anyone know if there is a microsoft fix for this bug? I searched the microsoft knowledgebase, but could not find any information on it.

What is the DLL property? Does the compiler links it using single thread or multithreading?

It actually is a lib, but I'm using this object in a exe and multiple dll's. All are compiled with the multithread option.
This isn't a sychronisation issue by the way, because I do protected access to my collections with critcial sections.

When I ran into the numerous STL bugs (using MSVC) I thought it was my mistake. More investigation showed that other people had the same problems. Even though it hurt me greatly, I simply had to abandon the STL and code my own containers.

It was not practical for me to use another STL implementation as I did not have the funds available.

My advice to you is to fix specific bugs that effect you. For example, you should be able to apply that fix mentioned on the dinkumware site.

In my experience, it seems MS have not fixed many of the bugs.

By using the file from the dinkumware site, the problem is solved. But I would prefer an actual microsoft fix, because now I have to make sure that I have replaced the xtree file on every pc my software is build. I rather apply some hotfix or something.
