Hope, the example below can help

graph::addvalue(int nummer, CString typ, CString kstartrnummer,int zeile, int spalte, CString betrag, CString text, int r, int g, int b)
{
	CString abfrage;
	char strbetrag[100];
	CString cnummer, czeile, cspalte, cr, cg, cb;

	sprintf(strbetrag, "%i\0", nummer);
	cnummer = strbetrag;
	sprintf(strbetrag, "%i\0", zeile);
	czeile = strbetrag;
	sprintf(strbetrag, "%i\0", spalte);
	cspalte = strbetrag;
	sprintf(strbetrag, "%i\0", r);
	cr = strbetrag;
	sprintf(strbetrag, "%i\0", g);
	cg = strbetrag;
	sprintf(strbetrag, "%i\0", b);
	cb = strbetrag;
	text.Replace("'", "''");

	abfrage = "INSERT INTO Graph (Nummer, Typ, Kstartrnummer, Zeile, Spalte, Text, Betrag, r, g, b) VALUES (" ;
	abfrage = abfrage + cnummer + ", '" + typ + "', " + kstartrnummer + ", " +  czeile;
	abfrage = abfrage + ", " + cspalte + ", '" + text + "', ";
	abfrage = abfrage + betrag + ", " + cr + ", " + cg + ", " + cb +")";
	db.ExecuteSQL(abfrage);
}

Good luck, Gérard

wcscpy(value,strLoggedInUser);
::SysFreeString(strLoggedInUser);

i know how to copy bstr, but my problem is that when i assign

BSTR b=L"hello";

some where in code the value of b changes to " some garbage value".

but if i use wcscpy, the value of b doesn't change.

please read my question and answer me.

Take a look at: http://msdn.microsoft.com/en-us/library/ms221069.aspx[^]

It is clearly stated that asigning anything to a BSTR should be done using SysAllocString. So using wcscpy or a regular asignment operator (=) is wrong by definition.

You can try something like this (I assume GetLoggedInUser() returns a wchar *):

BSTR strLoggedInUser = ::SysAllocStringLen( GetLoggedInUser() );

//..do something..

//Call this when you are sure the BSTR is no longer used!!
::SysFreeString(strLoggedInUser);

The above is fine.

The above is bad.

Use, instead

BSTR c = SysAllocString(b);

SetScrollInfo() not calling OnSize() of CDialog

Hai all,

In CDialog,zooming the image and scrolling works fine for dialog but not picture control(CStatic)of CDialog.
I am trying to load an image(any type) in picture control and zooming it.For that i am using the third party class where in contructor i am assigning picture control window.It displays the image and enable the scrollbar according to zoom.

Passing this->m_hWnd of CDialog inside my Zoomin()

SetScrollInfo(this->m_hWnd ,SB_HORZ,&m_HSInfo,TRUE)

This code is calling OnSize() of CDialog and diaplays image in dialog where i can access scrollbar,but if i pass my picture control window inside the

SetScrollInfo(hWndpicturecontrol,SB_HORZ,&m_HSInfo,TRUE)

it is not caling OnSize() of CDialog and i cant even access the thumb of the scrollbar.

I followed the sample by refering the below URL
http://www.codeproject.com/KB/cpp/GDI_.aspx

Thanks and regards
SatheeshKumar.

Hi,
I dont have Idea which is 3rd party class your using but you can use CFormview or CScrollview in the Dialogbox which make the you work easier.

I want to sell the antitheft software with source code, can you help?

Hello All,

Thank you all for reading the post!!!

My company has developed Anti-Theft software for Symbian series 60 2nd edition and UIQ 2 powered phones. We have also developed two types of windows based Key generators to give away the unique registration code to users to unlock the trial version. This software is currently live for sale on different online sales channels like www.handango.com and others.

We want to sell out this product with complete SOURCE CODE to any interesting company.

Yes, you read it right, it’s with source code!!!

We have a set of very formal reasons for it.

1. We are not interested in porting the application on the Symbian Series 60 3rd edition and other platforms
2. We are in a process to raise the funds to explore opportunities in the desktop software development.
3. We want that the masterpiece i.e. code created by our company should not be in vein.

This antitheft software includes 5 (FIVE) subprojects i.e. 2 .lib files,2 .mdl files, 1 .exe file and 1 .app files which are as follows:

1. First .lib file gives functionality of normal keygenerator to be embedded in the main app.
2. Second lib file gives functionality of RPN based keygenerator to be embedded in the main app.
3. First .mdl makes the application auto start on phone restart.
4. Second .mdl makes the application as MIME compatible.
5. .exe file provides functionality for uninstalling the application from the phone.
6. .app is the main application file.

Feature of software design:

1. Software is completely designed using object oriented technology.
2. Every single minute detail is documented.

Features of software:

1. Reads the IMSI, Cell ID, Country code and IMEI of the phone.
2. Remains invisibly installed in the phone and only authentic user can access it with the password. It cannot be seen even in the default list of installed applications.
3. Uses very low memory i.e around 200K of RAM in runtime.
4. Backs up all the contacts and SMS
5.I nvisibly sends SMS which cannot be traced in the phone. No log entries can be found.

I am in a search of potential buyer who can buy this complete system. I want to give away the product with exclusive rights to the buyer so that our role will be finished from the brand development and the buyer may customize it, rebrand it or resell it. Everything will be done according to the legal software acquisition agreement only. I am expecting not less than 20K USD (which is very very reasonable from our side) for this product. I will reveal the software name and the my company's name at the start of the discussion.

All interested parties are request to send their quote(s) at shaperu@gmail.com

I would really appreciate and reward any help to find out the potential buyer for me.

Once again, thank you all for reading the post!!!

P.S. : I believe that this is the place of developers and a developer can only understand the value of the SOURCE CODE

Hi Pallini,

Thank you for READING this thread.

I would like to know that why did you consider this post as ABUSIVE?

Also, I am not advertising any stuff here. I thought lots of software developers might have gone through this phase. I just wanted to have their suggestions.

Thanks!
