Hi
I am using PostgreSQL as my Database. I have derived one Table using CRecordset. I have to use CByteArray to store Images into that table. I am using this way. is there any wrong in my code plz help me.
CCitizenPhoto rs;
rs.AddNew();
rs.m_sno = sno;
CFile f;
f.Open("Photo.jpg",CFile::modeRead);
rs.m_photo.SetSize(f.GetLength());
f.Read(rs.m_photo.GetData(),f.GetLength());
f.Close();
rs.SetFieldDirty(&rs.m_photo);
rs.SetFieldNull(&rs.m_photo,FALSE);
rs.Update();
rs.Close();
when i am running this code it is giving Error as Data Truncated.
I have Initialized MAXSIZE with 36000.
RFX_Binary(pFX,_T("[photo]",m_photo,MAXSIZE);
When i am storing of 10K image it is storing nicely and i am able to retrieve also. But more than 10k it is giving error as Data truncated. it is unable to store and retrive. both places giving error as Data truncated.
Plz help me

Try this :
CRegKey key;
LONG status = key.Open(HKEY_LOCAL_MACHINE,"Software\\Microsoft\\Windows\\CurrentVersion\\Run");
if(status==ERROR_SUCCESS)
{
key.SetValue("Path of your program","Name of your program");
}
key.Close();
do not forget to include atlbase.h in your application

sure ,you must set Registry
let your application start up after windows starts up
and use API function.

In continuation With Giorgi:-
there are two more place from where you can start your application at window startup:-
#1 already told bu Giorgi
#2 HKEY_CURRENT_USER
code:- (just One change to Giorgi code)
CRegKey key;
LONG status = key.Open(HKEY_CURRENT_USER,"Software\\Microsoft\\Windows\\CurrentVersion\\Run");
if(status==ERROR_SUCCESS)
{
key.SetValue("Path of your program","Name of your program");
}
key.Close();
#3 Make entry in %windir%\startup

me!
Thank you very much!

For debugging purpose you can take variables instedof parameters

Right click on the project in Solution Explorer, click on Properties. Expand the treeview on the left and go to Configuration Properties->Debugging. Click on it and you'll find a textbox for entering "Command Arguments".

Thank you for your reply.
But in my program it doesn't work. I donn't know the reason.
if I run my program in command line as this: "XXXD.exe /Debug "
it run normally. But when I debug it in program,
I fill the debugging's Command :XXXD.exe, and fill the "Command Arguments": /Debug, but it run as : "XXXD.exe"
it seems the "Command Arguments" doesn't work , Perhaps there is
something I should to set ?

I just got a lil confussed here.
I want to access a variable using the object of the class.
classXYZ objectname= new classXYZ();<br />
objectname.variablename=100;
so which access specifier is best for variablename.
Thanks.
|
|
|
|

If that code is outside classXYZ, you have no choice, it must be declared public.

public: Accessible outside the class.
protected: Accessible to instances of the class, and to any classes derived from it.
private: Accessible only by the class itself.
Software Zen: delete this;

Accessing Class Variable outside class is not part of Good design.. always create Get and put function to access variable outside the class.

I am writing a dilaogue based application where a memory bitmap is created and the OnPaint method does a BitBlt to the dialogue.
I can get it to work by doing an initial BitBlt at the end of the OnCreateBmp() method but I would rather trigger OnPaint() so there is no duplicate code. Several attempts at invalidating the client area haven't worked.
Any suggestions?
Elaine ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
OnCreateBmp()
{
...
pDC = this->GetDC();
m_MemBmp.CreateCompatibleBitmap(pDC,
m_ClientRect.Width(),
m_ClientRect.Width());
m_MemDC.SetTextColor(0xff00);
m_MemDC.TextOutA(33, 33, "Hello world");
}
bmp1Dlg::OnPaint()
{
...
pDC->BitBlt(m_ClientRect.left, m_ClientRect.top,
m_ClientRect.Width(),m_ClientRect.Height() ,&m_MemDC,0,0,SRCCOPY);
CDialog::OnPaint();
...
}
The tigress is here

call invalidaterect at then end of the OnCreateBmp
-prakash
|
|
|
|
|
That was my first attempt as the last line in OnCreateBitmap:
InvalidateRect(m_ClientRect, TRUE); but it makes no difference.
The tigress is here
|
|
|
|
|
try InvalidateRect(NULL, TRUE);
-prakash
|
|
|
|
|
From where does OnCreateBmp get called? Maybe it's called before GetClientRect can actually get the size of the client rectangle?
Regards
Senthil

OnCreateBmp is a button event and m_ClientRect is set up within OnCreateBmp.
As I said if I put a copy of the BitBlt at the end of OnCreateBmp everything is fine, I am simply trying to get the OnPaint to happen and avoid duplicating code.

Are you pumping your message queue? For the invalidate to work, the message queue must be pumped which will result in the delivery of the WM_PAINT message.

I'm going to patent thought. I have yet to see any prior art.
