Sorry,
looks solved:

this is a wrong usage

this is correct

AFAIK either you need to owner draw it or Custom draw( LVN_CUSTOMDRAW ) it.

custom draw is only way to do so.. for that you have to subclass CListCtrl

hi I need to call the following function somewhere in a program:
void __fastcall TFormMain::btnUpdateClick(TObject *Sender)
{.....}
This is the event of mouse-click on a button.
How can i call this function in the program itself (which otherwise gets called on 'mouse-click'??

Try sending a WM_COMMAND message to the button
ex:SendMessage(WM_COMMAND,/*ID_OF_BUTTON*/);

Somethings seem HARD to do, until we know how to do them.

By calling it directly. I do not know how the function is implemented, so I do not know if it can handle a NULL Sender parameter or not - e.g.:

     btnUpdateClick( NULL );

If you have to call it outside of the TFormMain class, you need a way to expose it from that class.

Peace!

Hi,

You can di it like this:

void __fastcall TForm1::BitBtn2Click(TObject *Sender)
{
  // what ever code come here
}
//---------------------------------------------------------------------------

void __fastcall TForm1::BitBtn1Click(TObject *Sender)
{
	BitBtn2Click(Sender);
}

Makes sense ....

Check if exe exist at given location

Hi,I have a path (like "c:\path\programname.exe")
How can I determine if program 'programname.exe' exist in 'c:\path' directory?
I tried with 'FindFirstFile' and checking 'WIN32_FIND_DATA' structure, but for what 'dwFileAttributes'?
Thanks!

Re: Check if exe exist at given location

Garth J Lancaster3-Oct-07 23:52

there's a quicker way - something like :-

bool bFExists(LPCTSTR szText) {
struct _stat buf;
return (_stat(szText, &buf) == 0);
}

should be quicker if you dont need to iterate through the files .. you'll need an include for <sys/stat.h>

<br />
WIN32_FIND_DATA wfd;<br />
HANDLE hf = FindFirstFile("c:\path\programname.exe",&wfd);<br />
if (hf != INVALID_HANDLE_VALUE) {<br />
 FindClose(hf);<br />
 return TRUE;<br />
}<br />
else<br />
 return FALSE;<br />

but personally I just use

<br />
return (GetFileAttributes("c:\path\programname.exe") != -1);<br />

NB: in reference to the answer above the MSVC runtime function _stat() does a GetFileAttributes and a bunch of other stuff

The simplest way to check if a file is exists is to open it with a call to CreateFile()

There's also _access(), which is just a wrapper around GetFileAttributes().

The code listing is incomplete (missing information on sTmpExt), but my guess is that TrCharToUnicode(...) is overwriting the memory pointed to by szPathBuffer because it is not being told the size of the memory (in TCHARs) being pointed to by szPathBuffer.

Peace!

char to unicode means also that you need twice the amount of bits to store the output string. Confused | :confused:
