Do you want to save these values for next time that you run your program ?

You can save values on registry and when you want to run your program read of registry,also you can find examples on codeproject

launch iexplore from a win32 appl

Hi everybody

I have to launch iexplore.exe from a win32 appl developed into powerbuilder
environment. Anyone can suggest me a SDK to do this? I would like not to
hard-code iexplore pathname and launch through standard CreateProcess.
Due to my IDE, I cannot use COM or other microsoft component, only base SDK.
Also, if there are no API's to do this, anyone knows another mechanism (for
example a registry key for pathname)? All this to allow my appl run on any
windows installation, independently from version (2000, XP) and language

Thank you very much to everyone

If you want to launch iexplore.exe, regardless of whether it is the default browser or not, you'll need to use an absolute path, or resolve the CLSID {FBF23B42-E3F0-101B-8488-00AA003E56F8} to IE's path. You could also look for the HKCR\Applications\iexplore.exe\shell\open\command key.

If, however, you just want to launch the default browser, call AssocQueryString() before calling CreateProcess().

I surprisingly do not have this key, though using ie on my computer. Is this really reliable ?

I don't know. I was simply providing options for the OP to explore. The more he has to pick from, the more robust his application is likely to be.

I think the problem is just reliability
I've found also this registry key:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\IEXPLORE.EXE
But how can I be sure to find it or them on any installation? Confused | :confused:

anyway, thank you everybody for the help

I do not think this exists (I just searched through my registry).

Need it to be iexplore, or can it be the current web browser (in which case you may want to retrieve the path using registry file extensions) ?

hard-code iexplore

This can also be configured in some options of your app.

Hi,
I have declared int m_intValue; and wrote int GetValue(){ return m_intValue;} function.I have declared a structure

struct Table
{
int intData;
CString strName;

};
CArray<table*,table*>m_Tables;

Now i want to write a function same as GetValue() function which will return m_Tables.How to declare it ?

One such way would be:

typedef CArray<Table*, Table*> _Table;
_Table m_Tables;
 
_Table* GetValue( void )
{
    return &m_Tables;
}

Accessing variables and functions from another dialog

Hi
I have a dialog, that has a sub-dialog. When I have opened the sub-dialog, I may wish to have access to either a variable, of function within the main dialog. Can this be done, if so how?

The value of the variable could change whilst the sub-dialog is open, so I need to check its value before doing anything else in the sub-dialog.

Hope someone can help!

You can use of CMain *m_Main=(CMain*)GetParent();m_Main->Yourfunction

Thanks WhiteSky

Just did this - works OK - the only other thing I had to do was include the header file for my main dialog in the sub-dialog. This all seems to work now

Thanks for your help!

Pass a pointer of your current dialog to the sub-dialogs.

void MainDialog::DoSomething()
{
  CSubDialog dlg( this );
  dlg.DoModal();
}

and in your sub dialog:

/// header : 
class MainDialog;
class CSubDialog
{
  CSubDialog( MainDialog* pMainDialog );
};

/// cpp.
CSubDialog::CSubDialog( MainDialog* pMainDialog ) : m_pMainDialog( pMainDialog )
{
  /// do something with m_pMainDialog.
}

The Main dialog has a timer in it which still runs whilst the sub-dialog is open. I read in data from the parallel port, which I want the sub-dialog program to have access to, and write data out of the port.

Thanks for looking!

CString::GetBuffer(). Use CString::ReleaseBuffer() after using buffer.

no. GetBuffer() is not to convert but to get a pointer to the buffer encapsulated within the CString.
if you have to convert a CString, use the cast operators it provides instead, like (LPCTSTR)...

How it is different? It returns class's NULL terminated buffer, so can be used as char*. What you would term as if not Convert?

It's does same thing as above, get pointer to the buffer encapuslated within CString.
