I've added next code in TRY block

...
CString name,surname;
name="Jon";
surname="Doe";
int nID=200;
SqlString.Format("INSERT INTO Table1 (ID,Name,Surname) VALUES (%d,%s,%s)",nID,name,surname);

database.ExecuteSQL(SqlString);
...

but i get exception thrown , with message box : "Database error. Too few parameters.Expected 2"

after i modified the code like this :

SqlString = "INSERT INTO Table1 (ID,Name,Surname) VALUES ('200','jon','doe') ";

everything is ok ,do you know whats wrong with the previous code Confused | :confused:

thanks for help Cool | :cool:

[Fixed]

I found out why exception was thrown.
Instead of :

SqlString.Format(_T("INSERT INTO Recordset_name(ID,Name,Surname) VALUES<br />
(%d,%s,%s)"),i_ID,c_Name,c_surname);

I had to write :

SqlString.Format(_T("INSERT INTO Recordset_name(ID,Name,Surname) VALUES<br />
('%d','%s','%s')"),i_ID,c_Name,c_surname);

Hi Giorgi,

I use http://www.codeproject.com/database/caaadoclass1.asp[^]

With those classes, you first need to open a transaction in CADODatabase, then call AddNew in CADORecordset, then call CommitTransaction in CADODatabase to commit the changes to the database. Your classes might be similar. You also need to make sure that you have select and editing privileges in the database!

HTH.

Hi To add new Record
1. open RecordSet
2. Call AddNew()
3. Assign values to field variables (rs.m_Name = "John";)
4. Call Update()
but in this case I think your Recordset is readonly,you most open it using ODBC or DSN.

if you use VS 6.0 use Class Wizard to create a new class With bass CRecordset class, the CW ask you about your DB select DAO & select your DB. it do that for you.
& if you use VS .Net Choose Create new Class & Select ODBC classes, it is the same.

Hi,

I have two tiff images and I am loading them into CBitmap using GDI Bitmap class. I am using one of the image to paint the background of a dialog and its working fine. Now I would like to use the second image to draw on top of the first. The second image has some transaparent areas and those areas should be replaced with the image in the back( first image).

I tried several examples in Codeproject, But I am getting the transaparent area filled with blue.

Can someone pl. guide me on doing this.

Thanks
San

Try to create a new view which is
overlapped on the dialogbox.
The first image should be in CStatic
control.
The second image should be manually
drawn on the view by editing the
function OnDraw(CDC* pDC).
This might work but dont know about
the windows message realted to it.

Maybe you can use TransparentBlt() in NT. This is an easiest way to paint with a transparent color.

Hi there,
I have an addin to ms Word written in visual c++ implementing the IDTExtensibility2 interface.
I sink events properly and launch my functions...
My question is..how can I call those functions from a different c++ project?(that should be possible)
need I to register them as word native functions, can I use messages to call them?...

thanks and happy codding

Bitmap dialog

Hello Friends,
I'm developing an application in which there are few dialog boxes and i decided to make them colourful using bitmaps,So i used the OnEraseBkGnd function to load the bitmaps .but there was an mismatch between the dialog size and bitmap size so i decided to capture the size of the dialog and the bitmap,after which i repainted the dialog calling the BitBlt function many number of times.
Is there anyother way to load the bitmaps so that i dont have to call the BitBlt function more than once.I've attached the piece of code what i'm using now.it'd be great if someone could help me in this...
BOOL dialog::OnEraseBkgnd(CDC* pDC)
{

CBitmap bmp;
CBitmap *ptrBmpOld;
CDC dcMemory;
BITMAP bm;
CRect rect;
int i, j;
int nHor, nVer;
bmp.LoadBitmap(IDB_BITMAP1);
bmp.GetBitmap(&bm);
GetClientRect(rect);
nHor=rect.Width()/bm.bmWidth+1;
nVer=rect.Height()/bm.bmHeight+1;
dcMemory.CreateCompatibleDC(pDC);
ptrBmpOld=dcMemory.SelectObject(&bmp);
for(i=0; i<nhor; i++)
{
for(j="0;" j<nver;="" j++)
{
pdc-="">BitBlt
(
i*bm.bmWidth,
j*bm.bmHeight,
bm.bmWidth,
bm.bmHeight,
&dcMemory,
0,
0,
SRCCOPY
);
}
}
dcMemory.SelectObject(ptrBmpOld);
return TRUE;
}

You could use CStatic objects, to which you set the bitmaps using SetBitmap(HBITMAP hBitmap)

Yeh ur true Rajeev
As the the OnEraseBkgnd will be oftenly called
if ur going to do BitBlt in that function the
5speed will be slow .
Have u tried to use the same code with OnDraw
member function.
U can aslo try to add the code on WM_INITDIALOG.

take care
send me the feedback when u have dont it. Blush | :O
