RasSetEntryProperties returns ERROR_INVALID_SIZE on 2K but works fine on XP Frown | :-(

Code follows :-

RASENTRY re={0};<br />
re.dwSize = sizeof(RASENTRY);<br />
re.dwfOptions = RASEO_ModemLights|RASEO_ShowDialingProgress|RASEO_PreviewUserPw;<br />
re.dwfNetProtocols = RASNP_Ip;<br />
strcpy(re.szLocalPhoneNumber,"0,35");<br />
strcpy(re.szDeviceName,s);<br />
strcpy(re.szDeviceType,"modem");<br />
re.dwFramingProtocol = RASFP_Ppp;<br />
DWORD err = RasSetEntryProperties(NULL,"HelloWorld",&re,sizeof re,NULL,0);

I had done this on top of the header file [manually] :-

#undef WINVER
#define WINVER 0x501

Inno Setup opinion?

Ravi Bhavnani2-Sep-02 15:52

I'm about to release a new version of one of my products and find that the time has come to migrate from my existing installer (EDI Install Wizard, an ancient relic from the past) to something more modern (and free). After narrowing my choices to NullSoft[^] and Inno Setup[^], I've decided to try the latter.

I'd appreciate any good/bad feedback regarding Inno Setup, particularly comments about the accomapanying script generator helper programs such as IS Tool[^] and ScriptMaker[^].

Many thanks!

i use InnoSetup for everything i put out. it handles everything i've thrown at it nicely. for my needs, and for the price, it's nearly perfect. i do all my scripts by hand (my largest script is only like 30 lines, so it's a trivial task).

i've only found one or two oddball things that it doesn't do that i wish it did: like, i haven't found a way to make it install to a specific folder based on the contents of a registry key, for plug-ins (read the key to find the location of the host app, then install to that folder). but that's not really a big deal.

I use the installed that comes with VS.NET. It integrates very nicely with my source code.

With just one step, I could rebuild all my projects and have them packaged in an MSI file (wizards and all).

Quite a time saver.

Thanks for your reply, Jeremy! I think I'm going to try InnoSetup for now because I don't want to have the user download MSI. (Many of my users run Win9x/ME).

ScrollWindowEx

Probably a simple question. i'm trying to call ScrollWindowEx as a method of the object CListBox yet the list box is not scrolling to the position I would expect it to go.

So far i have this,

ScrollWindowEx(0, rt.bottom, &rt, &rt, NULL, &rt, SW_ERASE | SW_INVALIDATE);

Perhaps I'm misinterpreting the parameters.

Anyone have some familiarity with this method?

Thanks!

Internationalization

Could somebody point me to some internationalization (localization) code, on how to write such an app? I have to write a bilingual app, and I have to rely on the locale, not only the language (for money, date displays).

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

try looking up GetCurrencyFormat() on msdn and this will point you to all the other locale related API functions.

delete function for ADO

I have:

void DbClass::DeleteRecord( int nIndex)
{

	m_pRecordset->PutAbsolutePosition((PositionEnum)nIndex);

	m_pRecordset->Delete(adAffectCurrent);
	m_pRecordset->UpdateBatch (adAffectAll);

	m_pRecordset->Requery(-1);

}

Is this adequate ? After deleting say ,record#4, and after the requery, where is my recordset pointing to?

Instead of requery should I do a movenext or something? Danger is what is its the last record? Then do I go one back? Very unsure Unsure | :~

Slow Finds

I have an MDI app that uses a RichEditCtrl for one frame of its view. When a file is opened, the data goes to the RichEditCtrl. On the OnInitalUpdate I do the following.

SendMessage(WM_SETREDRAW,(WPARAM)FALSE,0);
ExamineJournalFile();
SendMessage(WM_SETREDRAW,(WPARAM)TRUE,0);
Invalidate(TRUE);

The ExamineJournalFile() basically does searches on the text in the control and does some cleanup and highlighting. However, it does this for 10 different keywords, and then places the file location of those keywords into a treeview in a splitter window.

Functionally, everything is fine. My issue is with the speed on large files. I have just begun to play with threading the finds, but I am not sure if that is the safest or the best way.

Anyone encoutered this, or have a better suggestion?

Thanks

What search routine are you using? I think this can make much of a difference. Fast search routines are based on the so-called Boyer-Moore algorithm (do a search on the net for info and implementations).

Curently I am using the FindTextSimple() function of the CRichEditView class for the searching because I also need the position (but I guess as long as I know its a position, the row&col can be calculated).

I presume you're traversing the list 10 times ? Why not provide a vector & as an arguement to ExamineJournalFile and search for all 10 at the same time ? Threading is also probably a good idea if you want your UI to be responsive while this occurs.

The other option is to put your data into a set as you read it, because then searches will be a whole lot faster.

vector and set are part of the STL, if you don't know. Plenty of articles on CP if you need to know more, I've written several.

ExamineJournalFile does this:
{
//some text changing and highlighting in the view
FindItems("Chk", "Checks", 5,15,true, true, false,true);
FindItems("Tbl", "Tables", 5,3, true, false,false,true);
FindItems("CE:", "Employees", 7,69,true, true,1,true);
FindItems("CC:", "Cashiers", 7,80,true, true, false,true);
FindItems("Cancelled", "Cancelled", 16,13,false,true, true,false);
FindItems("Payment", "Payments", 18,11,true, true, true,false);
FindItems("No Sale", "NoSales", 18,11,false,true, true,false);
FindItems("Change Due","Change", 15,14,true, true, true,false);
FindItems("Cash", "Cash", 21,8, true, true, true,false);
}

FindItems goes thru the text of the control using FindTextSimple, takes the returned found position and then places the "index" in a treeview control.

I will look at putting the data into a set on the reading of the data. During the serilizing of the archive? Is the set still going to be faster than on a CString::Find()? I would think that ultimately, thats all the CRichEditView::FindTextSimple() does.

Anyway, thanks for the ideas.
