relative PIDL to an absolute PIDL?

4-May-03 11:22

Can't say I ever needed the aspect ratio for the screen resolution.
Isn't it enough with width and height?

if (lpdd->SetDisplayMode(width,height,bpp,0,0)!=DD_OK)

::GetSystemMetrics(SM_CXFULLSCREEN)
::GetSystemMetrics(SM_CYFULLSCREEN)

and

SetMapMode
The SetMapMode function sets the mapping mode of the specified device context. The mapping mode defines the unit of measure used to transform page-space units into device-space units, and also defines the orientation of the device's x and y axes.

int SetMapMode(
HDC hdc, // handle of device context
int fnMapMode // new mapping mode
);

Parameters
hdc
Handle to the device context.
fnMapMode
Specifies the new mapping mode. It can be any one of the following values: Value Description
MM_ANISOTROPIC Logical units are mapped to arbitrary units with arbitrarily scaled axes. Use the SetWindowExtEx and SetViewportExtEx functions to specify the units, orientation, and scaling.

Problem with POP3

I want to connect to my mail server and get my emails.This is my code:

WSAStartup(0x0101,&wsa);
sock=socket(AF_INET,SOCK_STREAM,IPPROTO_TCP);
HOSTENT *hp = gethostbyname("mail.parsonline.net");
sin.sin_addr.s_addr=*((unsigned long*)hp->h_addr);
sin.sin_family=AF_INET;
sin.sin_port=htons(110);
int i = connect(sock,(struct sockaddr*)&sin, sizeof(sin) );
char *buff="USER mazdakmansouri\r\n";int y;
send(sock,buff,strlen(buff),0);
recv(sock,buff,10,0);
i = WSAGetLastError();

But I recieve nothing andreturn value from recv() is -1 and after that line WSAGetLastError() return error 10053 which means "An established connection was aborted by the software in your host machine".Before that WSAGetLastError() return 0. (no error) Any suggestion?

Linking Error related to SerializeElements template

Hi,

I am using the SerializeElements template and specify 5 of them, each used to allow the serialization of classes I built. 4 of them compile fine but there is one that casues a
linking prolem that suggested that the template is defined in two different locations. Here
is the message:

SupaKewlDoc.obj : error LNK2005: "void __stdcall SerializeElements(class CArchive &,class IRCchannel * *,int)" (?SerializeElements@@YGXAAVCArchive@@PAPAVIRCchannel@@H@Z) already defined in IRCnetwork.obj
Debug/SupaKewl.exe : fatal error LNK1169: one or more multiply defined symbols found

Now the code compiles if I remove the template for the IRCchannel. Also I have done a find
for IRCchannel template elsewhere in the code and it definitely is only defined once.

I was thinking it maybe due to how the included statements are structured. I have included below the start code for the two files SupaKewlDoc and IRCnework. I'd appreciate any help or suggestions. Thanks a bunch.

Compiling database Project

progman4-May-03 1:12

4-May-03 1:12

I have project with database support.

Does it possible to complile this project in one *.exe file ?
(i.e. database will be included into the *.exe module).

Or maybe ypu are have some other ideas - how i can to hide my data's ?

regards !

jmkhael4-May-03 2:32

Several options i can think of:

- Encrypt the data before inserting it into the database
- Encrypt the database file so it would be unreadable
- U can add the database file into the resources and on runtime get the handle to it, unpack it, decrypt it, do what u wanna do and the update the resources

Try to look on code project for some algorithm of encryption and on MSDN for resource management and UpdateResource Api family
hope this help

Databases are usually stored in files on the harddisk. If you
store data in the .exe then you have to make a new .exe every
time you change the data. It is not impossible but I can't
remember ever seen it done.

If you want to hide your data you must encrypt it
before storing it in the database.

well , but i actually don't want to change data in database. It's will be permanent data storage - it can be changed only during project compliling. So if it is possible to store database file in *.exe or *.dll module - tell me please, how can i do it ?

regards

jhaga4-May-03 4:02

CString row1="This is data row 1"
CString row2="This is data row 2"

etc.
You can have you whole database in one CString.

well , but most data will be in binary data .. To store this data in the resource *.rc i think it's quite difficult , because there is about 20K items to store .. So how can i handle this problem ?

By the way - how to put and get from table binary data's ?

thanks !

jhaga5-May-03 12:10

5-May-03 12:10

Sorry, I have not answered you. But believe me,
I am not the right person to to give anybody advices
on how to store a binary database in the resources.

Tell us what kind of binary data you have (bitmaps jpegs?) and
maybe somebody else can answer you.

progman5-May-03 14:10

Yes, if it will be , jpegs - how could i store them ?

If its a static database then use a CArray and a structure. It can hold more information than you think.
