hey guys,

i've seem to have one problem with 'InnoSetup' ( a program creating setups).

I've added to script that install has to make a desktop shortcut. After install, i open the shortcut. The program launches.
But then i get an error (error opening database file).
'Can not find c:\..\desktop\....db' file
The program searches in the directory where the shortcut is made!
It needs to search the database file in the same directory where the program executable really is (not where the shortcut is).

The same happens when i open the shortcut on start-menu. It searches the database files where the start menu group is located at.

The strange this is .. if i make a shortcut from my program to the desktop, i don't get this error and program is executed correctly.

Anyone who can fix this problem?

Greetings
Jens

I had exactly the same problem as you do. When the program runs from the start menu for some odd reason it thinks that the current running directory is the desktop (or the path the desktop ini file). To fix this problem you need to do the following:

LPTSTR szCmdLine;
szCmdLine = ::GetCommandLine();
CString strPath( szCmdLine );
// Remove the exe name from the path. _splitpath can
// be used instead.
int iCharPos = strPath.ReverseFind( '\\' );
strPath.SetAt( iCharPos, '\0' );
// This loop removes '"' from the beginning of
// the path string.  Windows encloses the path in quotation
// marks (don't ask me why).
for( int j = 0; j < strPath.GetLength() - 1; j++ )
{
	strPath.SetAt( j, strPath[j+1]);
}
if(!::SetCurrentDirectory( (LPCTSTR)strPath ) )

This problem is not innosetup related.

AFAIK you have to set the working (start in) directory for the shortcut.

In the [Icons] section, set the directory in the WorkingDir entry. See your InnoSetup help files for more info.

PJ Arends, it is not possible to set a working directory because the user can specify the directory himself.

Or am i misunderstanding?

<edit> I think this is a innosetup related problem because, if the user himself makes a shortcut to the program the program will be launched correctly

I don't think that this problem relates to InnoSetup at all because I had to deal with this problem when I used InstallShield and Windows Installer.

You are misunderstanding. You set it to {app} which is where the user selected the application to be installed.. See the documentation on that PJ suggested.

You are so right. Sorry but I didn't really read your message and I wrongfully insisted on my answer.

hi there

i have a problem...

i added a lib (+ description header file) to my test project ... ( cwinapp + own editet cdialog ) all works fine ...

but when i try to add a declare_message_map and a begin_message_map the dialog wont be shown anymore...(but it works without problems when using a windowproc...)

can it be that there is a problem in the lib/header?

(perhaps its a common problem and all of you know what im talking about? Wink | ;)

)

Hi
If you have implemented a new dialog (a child of CDialog) with the functions from the Visual Studio, you have in this dialog-class a message_map and you don't must implement a new message_map.

For Windows messages use the class-wizard to create the handle-functions e.g. OnCreate() for WM_CREATE (see below in the message_map -> ON_WM_CREATE())

For your own messages use the macro ON_MESSAGE in the excisting message_map
e.g.
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)
ON_MESSAGE(WM_OWN_MESSAGE, MyOwnFunction)
//{{AFX_MSG_MAP(CMainFrame)
ON_WM_CREATE()
.....
END_MESSAGE_MAP()

If your dialog complete without MFC, use the windowproc()-function

Frank

Hi Guys!!

I want to check Internet connectivity on my machine. I`ve reproduced my code below.
The code works fine except if IE is in offline mode.i.e i am unable to detect offline mode..

#include "stdafx.h"
#include "Wininet.h"

int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
BOOL bConnected = FALSE;
DWORD dwFlags;

bConnected = InternetGetConnectedState ( &dwFlags, 0 );
if ( bConnected )
if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
bConnected = FALSE;

if (bConnected )
MessageBox(0,"WOW ! Internet is Connected !","",0);
else
MessageBox(0, "Oops ! Internet is not Connected !","",0);

return 0;
}

Regards!!

Abhi

P.S Tony, Ryan please have a look.

Isn't bConnected false when InternetGetConnectedState returns? What is the return value?
Let's ignore bConnected for a moment.
Change these lines:

if ( bConnected )
   if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
        bConnected = FALSE;

to:

if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
    bConnected = FALSE;

and tell me what happens. What is the value of dwFlags?

Ya the bConnected value is false in Offline mode too.
I tried by removing the condition [if(bConnected)] but still does not work.

The value of dwFlags "in disconnected and Work offline mode" is 16 Confused | :confused:

while in connected mode it is 18.

Do u have any clue?

How make CDatabase instance gobal

25-Jul-03 12:07

If bConnected is false then it means that the internet is not connected (but I believe that you know that already). I thought you were getting bConnected = TRUE, even though you were offline. That's why I asked you to remove [if(bConnected)] just too see what would happen. You shouldn't get worried about the dwFlags value. I bet you want to know why the dwFlags doesn't have the INTERNET_CONNECTION_OFFLINE flags set? Sorry, but I don't have an answer for that.
To wrap things up, your code works fine.

Hi all,

I want to create an application in VC++ and have the following question.
1. Which project type i should choose, whether MFC.exe or AppWizard.

2. After creating interface, User should login to application. This login user id and password at the value avaible in database(MSaccess). Here say on OK action i create CDatabase Instance and open the database.

I want to use this instance for the rest of dialog to open other tables in the database. My question is how to make it gobally avaible.

Can someone point to me a link or good site. I am beginner in this language.

Thanks in advance,

Regards
Valli

Make your CDatabase instance a member of your CWinApp derived class. You can then access it anywhere in your project by using AfxGetApp.
