Re: How to Add Start menu shortcut in Setup program

I think the problem is not with the insatalshield but in ur application code..
Ur reading for sat file may be wrong..(i.e)The path u have given for reading the .dat file is relative with ur exe....So the application is searching is the oath where start menu short cut resides....
U have to explictily give the full path of ur exe dor reading the .dat file..
If u can give the code for reading of .dat file and i can clearly analaysis the problem Big Grin | :-D

cheers,

Mani,

Thanks for your response. Yes, I am using a relative path, but I was doing it thinking that since the user may choose to install the my program under any folder, I should give a relative so that it will be able to open the my .dat file as long as they are together in one folder regardless of the folder chosen by the user during installation.
When I manually create a short cut of my EXE file and put it on the desktop or in the start menu .. it reads the .dat file fine. I was thinking that an icon created by the setup program should work the same way.

I am attaching my code. Thanks for looking into it.

<br />
       //open config file to read institute name information;<br />
	char *pszFileName="config.dat";<br />
	char pszIName[256];<br />
	CFile myFile;<br />
	CFileException fileException;<br />
	if ( !myFile.Open( pszFileName, CFile::modeRead, &fileException ))<br />
	{<br />
		::MessageBox(NULL, "File doesnt exist ","Warning",MB_OK);<br />
       <br />
	}

Also I have a trivial question. Why do I have to put :: before Messagebox function sometimes to make it work. Sometimes it is works without the dots.
As you can probably see that I do lack some of basic knowledge of MFC. Smile | :)

Thanks for your help!

Sincerely,
Anjum.

Yeah thats the problem.......
U should nver give the relative path..I will not work...In this code when u run with start menu it will search the folder of startmenu and never the exe..So its better u use Absolute path of exe...
So use this piece of code..

<br />
CString StrLaunched;<br />
TCHAR szFullPath[MAX_PATH];<br />
TCHAR szDir[_MAX_DIR];<br />
TCHAR szDrive[_MAX_DRIVE];<br />
::GetModuleFileName(NULL,szFullPath,MAX_PATH);<br />
_splitpath(szFullPath, szDrive, szDir, NULL, NULL);<br />
StrLaunched.Format(_T("%s%s"), szDrive, szDir);<br />
char *pszFileName=StrLaunched+"config.dat";<br />

This will work.....
Then :: means ur calling an Windows Sdk function Big Grin | :-D

I can't seem to get the scroll bar of my edit box to display on the left. I've tried using the left scroll bar style but the scroll bar stays on the right. How do I get it to display on the left.

Scroll bars can be aligned to the left (using the WS_EX_LEFTSCROLLBAR style), but they take effect only in Hebrew and Arabic versions of Windows 95 (and any languages whose characters can be read from the right).

You give no reason for which a left-aligned scroll bar would be beneficial.

Note For the messages, notifications, and structures used with grouping, insertion marks, and tile-view, see the list-view documentation in the Platform SDK.

Dialog App how do I get VK_RIGHT???

I need to get VK_RIGHT but I cant seem to figure this out...

void CAlienMemoryDlg::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
// key is pressed
int x;
x = -1;
CDC *xDC=GetDC();
switch(nChar)
{
case VK_DOWN: // down arrow key
{
break;
}
case VK_UP: // up arrow key
{
break;
}
case VK_RIGHT: // right arrow key
{
m_CurrSelected++;
if (m_CurrSelected > 11)
m_CurrSelected = 0;
x = 0;
break;
}
case VK_LEFT: // left arrow key
{
m_CurrSelected--;
if (m_CurrSelected < 0)
m_CurrSelected = 11;
x = 1;
break;
}
}
if (x > -1) {
Game.SelectImage(m_CurrSelected,xDC,x);
}
CDialog::OnKeyDown(nChar, nRepCnt, nFlags);
}
VK_LEFT works but VK_RIGHT doesnt

OLE Drag Drop without MFC

23-Jul-02 11:50

Hi!
can anybody help me out with it? I need to write a MFC-free app that supports drag-drop via OLE (I use the WM_DROPFILES method already but it's not sufficient). I have a hard time figuring it out. Even MSDN says use COleDataSource as if nobody ever programmed for WinAPI (Is there anybody out there/Pink Floyd). Can anybody give me some clues? A snippet would be COOL. Thanks a lot

losing stdin when redirecting stdout and stderr

I seem to be losing my 'stdin' when I redirect my stdout/stderr (using freopen). Better put, the stdin seems to become flaky...

Does this make sense to anyone?

Is there a better way to get keystrokes from a (DOS/console/Win2k) app than using getch()? w/o using an event loop?

Thanks in advance....!

drag drop, list view

has anyone here ever sucessfully implemented smooth drag-n-drop for a listctrl in 'icon' view ?

i've searched the web for days for a way to do it (yes, i've seen codeguru) , but everything i've found and everything i've tried results in horrible flicker.

fyi, the flicker is casued because, in MouseMove, UpdateWindow on the listctrl to redraw what the drag image has uncovered, then i redraw the drag image in the new spot. so, each move, i have to redraw the list, the redraw the drag image.

i've tried all kinds of variations on LockWindowUpdate, DragShowNolock, UpdateWindow, etc... nothing seems to get rid of the flicker.

What all are you doing in your drag? Just moving a drag image over the list, or are you drawing insertion marks, etc.? I've never had serious problems with the first, but *always* get something wrong with the second.

The same thing I want to do.I have two list views .Left list contains directories,subdirectories and files. I should be able to select some part of the list and should be able to drag and drop into the right pane(or list view) and copy these dirctoris and files into a particular location.How can implement this?Any existing code is there so that I can resuse it in my application?
please help me.I am running out of deadlines.
Thanks in advance.

it's an icon view, so i don't have an insertion mark.

what i do in OnMouseMove (currently, and it works no worse or better than anything else i've tried):

1. HitTest to see which item the drag is over

2. if it's an item (and not the item we were over the last time), set the new item highlight state and clear the old item's highlight state

3. regardless of hittest:
DragShowNolock(false)
UpdateWindow
DragShowNolock(true)
DragMove

4. then handle the out-of-rect stuff to do an autoscroll effect (this isn't the cause of the flicker, as it only kicks in when you've left the client rect)

i can move the DragShowNolock(false) anywhere before 3, with no effect

i can put the DragMove anywhere with only slight effect. sometimes, i can make it so the drag image is under the list items.

i get a really nice smooth draw if i get rid of both DragShowNolock calls, but then the listview items don't repaint themselves correctly.

A possibility for you might be to use the technique Windows Explorer appears to use on Win2k and up. Handle the d&d process as you are now, but instead of using the ImageList d&d support functions, create a small window to display the drag image and position it under the cursor. When the mouse moves, do the highlight and reposition the drag window. If running on Win2k and up, you can use the WS_LAYERED style to prevent excessive redraw as portions of the list are uncovered - and as a side bonus do that cool faded-edges effect like Explorer Wink | ;)

I might try a test implementation later, will let you know if it works well.

Talk about your dead thread replies! But i had no need to do drag'n'drop from early 2001 until now, and didn't have the motivation to try anything new. So this monday i finally tried doing a floating pop-up window to show drag images and thus am able to report that it works quite well. While no doubt you long ago either solved your problem or lost all interest, this was the thread that got me thinking about easier/better implementations, so i felt i owed it something.

CDatabase.OpenEx -> obstinate DSN?

Leonard23-Jul-02 9:06

Leonard

23-Jul-02 9:06

Hello there.

I have an MFC application running on Windows2K that opens a CDatabase object like so:

CDatabase cDB;
DWORD dwOptions = CDatabase::useCursorLib | CDatabase::noOdbcDialog;
cDB.OpenEx ("DSN";"****";"****", dwOptions);

For some reason though, if I alter the configuration for DSN (using the ODBC admin tool in Control Panel) such that it points to a different server, the application still tries to connect to the first server.

This is odd as, when examining the DSN directly (using the admin tool) it points to the new server alright - it's only when my application uses the above function call that the DSN seems to point to the original server. (And I am restarting the application)

Has anyone ever come across anything like this before??

Hmmmmmm....
