The best way to do this is to get the folder from the application .EXE path.
To do that, you need to use the Win32 API GetModuleFileName(). That API will return the complete pathname of the calling process' EXE. Unfortunately, it can return an 8.3 style filename and can mangle your directory names. I've included a Win95 safe short->long pathname conversion function ( Win95 doesn't support this ). Finally, once you have a nice looking path, you chop off the .EXE name path off with another funciton I've included GetPathOnlyFromPathname.
CString MyPath =
GetPathOnlyFromPathname(GetLongPathname(GetAppPathname()));
where you have the following 3 utility functions:
CString GetAppPathname(void);
CString GetLongPathname(const CString & ShortPathname);
CString GetPathOnlyFromPathname(const CString & PathName);
// returns the full pathname of the application
CString CVChatApp::GetAppPathname(void)
{
char szAppPath[2048];
GetModuleFileName(NULL, szAppPath, sizeof(szAppPath));
return (GetLongPathname(szAppPath));
}
The GetModuleFileName call will return an 8.3 style pathname to the EXE. You may want to convert that into a long filename so the directory name doesn't get mangled:
// convert a short DOS type 8.3 pathname to a Long Filename is the
// version of Windows support the export of the "GetLongPathName" API ( Win95 doesn't )
CString GetLongPathname(const CString & ShortPathname)
{
CString FullPath;
// Win95 doesn't have the GetLongPathName function,
// so we need to check the dll to see if it exists to avoid
// a fatal run-time error.
// Also, note that the name of the function as specified in the DLL
// is different than the called name, due to UNICODE macro preprocessors
// AND, I think GetLongPathName is a pascal-style called function, so
// have to add __stdcall (__cdecl is the default, which is buggy)
HMODULE hm;
hm = GetModuleHandle("kernel32.dll");
typedef unsigned long (__stdcall *PFI)(LPCTSTR lpszShortPath, LPTSTR lpszLongPath, DWORD cchBuffer);
PFI pGetLongPathName;
FARPROC pTemp;
pTemp = GetProcAddress(hm, "GetLongPathNameA");
char strLongName[MAX_PATH];
strcpy(strLongName, "");
if (pTemp != NULL)
{
DWORD dw;
pGetLongPathName = (PFI)pTemp;
dw = (*pGetLongPathName)(ShortPathname, strLongName, MAX_PATH);
}
else
{
strcpy(strLongName, ShortPathname);
}
FullPath = strLongName;
return FullPath;
}
and you'll need one other function:
CString GetPathOnlyFromPathname(const CString & PathName)
{
CString PathOnly = PathName;
// ReverseFind the first '\'
int iFound = PathOnly.ReverseFind('\\');
if(iFound != -1)
{
PathOnly = PathOnly.Left(PathOnly.ReverseFind('\\'));
// put a trailing '\' on if the last char is a ':'
if(PathOnly.GetAt(PathOnly.GetLength()-1) == ':')
PathOnly += "\\";
}
else
{
PathOnly.Empty();
}
return(PathOnly);
}
Hope this helps...

Hi there I was wondering how you can increment an ActiveX version automatically after every build.
I was also wondering how you can access the version information provided under resources in Visual C++.
thanks

Hello,
I want to create a control which basically encompasses MS Word/ MS Project.
Basically my application needs a dialog box where it has a button and MS word window (The entire window along with menus and toolbars) in it.
How should I go about.
I tried the standard OLE method. Added MSWORD9.olb type library into the project and got its associated class. Then I created an object of application class and instantiated it. Added a document and finally made it visible.
Then I tried getting handle to the word window and tried making it a child window of the control. But this doesnt seem to work (I basically cant move the window into the control).
I am sure this is a wrong way of doing it. Can anyone tell me how should I create such a control.
Thanks
Arvind
The following is a snippet of code I added in the control's OnDraw Function.
COleVariant vTrue((short)TRUE), vFalse((short)FALSE), vOpt((long)DISP_E_PARAMNOTFOUND, VT_ERROR);
_Application oWordApp; // this is part of MSWORD9.olbDocuments oDocs;
_Document oDoc;
oDocs = oWordApp.GetDocuments();
oDoc = oDocs.Add(vOpt, vOpt, vOpt, vOpt);
m_bFirstTime = FALSE;
oWordApp.SetVisible(TRUE);
m_szDocName = oDoc.GetName();// this will set the value for the member variable m_hWordWindow
::EnumChildWindows(NULL, WndProc,(LPARAM) this);
::SetParent(m_hWordWindow, m_hWnd);
::GetWindowLong(m_hWordWindow,nIndex);
::SetWindowLong(m_hWordWindow,GWL_STYLE,nIndex&(~WS_CAPTION|WS_TABSTOP|~WS_POPUP));
GetClientRect(&rWndRect);
ScreenToClient(&rWndRect);
ClientToScreen(&rWndRect);
::SetWindowPos (m_hWordWindow,NULL,rWndRect.left,rWndRect.top, (rWndRect.right-rWndRect.left),(rWndRect.bottom-rWndRect.top), SWP_NOACTIVATE|SWP_SHOWWINDOW|SWP_DRAWFRAME);
::MoveWindow(m_hWordWindow,rWndRect.left,rWndRect.top, (rWndRect.right-rWndRect.left),(rWndRect.bottom-rWndRect.top), TRUE);
Can Someone Tell me where I have gone wrong and what I should do. Any help would be greatly appreciated.
Thanks

I am currently having problems with the CSocket Class. My main problem is that when I call the Accept(), function my program will crash. I believe I am using all the correct parameters. Even in sample programs that I have downloaded it does the same thing, I was wondering if perhaps it had to do with me using Win2k. Any help will be Greatly Appreciated.

Here is a sample of code I'm using and it works fine.. I am all so running windows 2k pro.. so I doubt that the OS is the problem.. If this doesnt help, I could email you the whole project I made and you can try to run it on your pc to rule out OS or what not..
void CChatDlg::OnAccept()
{
if(m_bConnected)
{
//create a rejection socket
CAsyncSocket sRjctSock;
//Acept using the rejection socket
m_sListenSocket.Accept(sRjctSock);
//Close the socket
sRjctSock.Close();
}
else
{
//Accept the connection request
m_sListenSocket.Accept(m_sConnectSocket);
//Mark the socket as connected
m_bConnected = TRUE;
UpdateData(FALSE);
}
}
Hope this helps..

Hi!
I need to create installation program for a few applications with dependency
between them(one application run another etc.)
Between files i should install there are some .ocx(ActiveX) or even
COM objects that i should register in the registry of local machine.
I'am trying to use InstallShield of the Visual Studio but i do not
understand how can i know(maybe there are some functions available in script) if the specified .ocx or .dll is already registered on that machine or not. This deal seems me to be confusing(I'am not familiar so good with registry).
Could somebody help me.
Thank you.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

If i can understand your question i use InstallShield the part of Visual Studio and its help but as i said before the my probem is having .ocx .dll to know if these files are already registered in that machine or not.
Sorry for telling my story anew.

Hi,
If I understand your question correctly, what you need to do is create a "Component" specifically for these shared self-registering files. If you select the Component in InstallShield, and look at its properties, you will find one for "Overwrite". What you need to do is select the criteria for overwrite. Usually, you will probably want to choose "Overwrite files BY VERSION THEN DATE" with both the NEWER options as well. This means the install will only ever overwrite these files if they have a higher version than the currently installed ones.
The self-registering bit is a whole other kettle of fish. You need to create a "File Group" for self-registering files as well (basically, the Component I mentioned above will contain this "File Group"). If you view the File Group properties, there is a self-registering option which will allow you to mark all of the files in this File Group as self-registering.
So, if you create a Component and File Group as described, Installshield SHOULD check the version of existing OCX and DLL files, overwrite them if your installer's files have a higher version, and then register them. Note that if a program on the install machine is using one of these registered files, you will get the "You need to reboot your machine..." message once the install is finished, and Installshield will register these files after the restart.
Hope this helps.

After years of default Msdev looking I have completely reworked its toolbar and menu, added a lot of tool found here and added several custom icon.
Now how can I save all this modification in order to restore after an (eventual) crash or to restore on another computer to have exactly the same environnement ?
Thanks for any help I searched but didn't found anything on this.

The following proc should find the record(contract)in db based on type(takes the position in the file and compare to the Type in the db).Proc. should return contract for use in different proc.
Please help...I can't understand why it's not working.
dbproc_get1 ->connection to SQL
int find_record()
{dbcmd (dbproc_get1, "select contract from type");
dbfcmd(dbproc_get1,"where type = %d",Type);
// Send the command to SQL Server and start execution.
dbsqlexec (dbproc_get1);
// Process the results.
if (dbresults (dbproc_get1) == SUCCEED)
{dbbind (dbproc_get1, 1, INTBIND, 0, (BYTE *) &contract);
while (dbnextrow (dbproc_get1) != NO_MORE_ROWS)
return(1);
}

Try appending an extra space to the first SQL string.
dbcmd (dbproc_get1, "select contract from type ");

I've never used CTreeCtrl before. They seem pretty straightforward an far as populating the tree items but I was wondering what the best way is to display a directory listing, similar to the openfile dialog or explorer directory tree, on a control on a custom dialog.

How do I change the color of my dialog? I have tried to use setBkColor but I haven't managed to get it to work. I also want to set backgroundcolor on a static text.
First I must get a reference to the text and then set the backcolor I guess?
How do I get this reference?

Hello all,
I've created new MFC AppWizard(exe) (SDI, but it doesn't matter),
my CView-class was inherited from CRichEditView class
(I turned on OLE support),
so, that's ok. It's compiled and worked.
Then I entered some character and tried to print them.
When I tried to do it on my Win2k server (service pack 2) I've got an extra blank page  printed.
On NT 4.0 (Service Pack 6e) everything is OK.
I use MSVS 6.0 Service Pack 5.
So ?

Hello!
I'm trying to use COleDateTime::ParseDateTime to parse a string according to a format that isn't in the locale. I use
SetLocaleInfo(LOCALE_USER_DEFAULT,LOCALE_SSHORTDATE,myFormat); to set the date format and then ParseDateTime(myDateStr);
But ParseDateTime will return an error and the date isn't valid.
Anyone that know how to make this work!??

The last param in the ParseDateTime method is used to specify a locale ID. Have you tried this?
