It all depends on design requirements such as the amount of the data, speed, reliability, etc.

Thanx for your reaction, but I need a start . There must be a standard protocol in VC++ to communicate from the mainprogram with objects.
I've seen some simple chatapplications where they use pointers to send data. In the mainapp there is a pointer to a CSocket object and the CSoscket object has a pointer to CDocument for example. But what I'm interested in is there must be some kind of a rule so you can communicate with other objects. Maybe I want to build in a mp3-player in my app, wahtever. So I hope you proud Wizzkids can help me out  ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

I have created a program using the doc/view architecture, and using CEditView as the view window. When you are typing something, and then save the document, the caret is moved back to the start of the text, and I want to know how to stop this from happening.
I have tried responding to the ON_FILE_SAVE message, and finding the position of the caret with pCaretPoint = CEditView->GetCaretPos(), then calling CDocument::OnFileSave(), and then using CEditView->SetCaretPos(pCaretPos) to set the caret position to its initial position, however I think the caret gets re-set after CDocument::OnFileSave() as this has no effect.
Any help is much appreciated

I created a resource only dll and have been trying to load it into my project without much luck. The code to load the dll essentially
HINSTANCE m_hinst;
m_hinst = LoadLibrary(name.dll);
Instead of a pointer to the dll, the return value is continually, 0x10000000.
Do I have some dll project settings incorrect, or am I doing something wrong?
|
|
|
|
|
if LoadLibrary() is returning 0x10000000, then 0x10000000 is the "pointer to your dll" aka the dll's load address.

Any ideas? Is their any way to programmatically have a printer
already selected if you know the name of the printer you want to
print to?
Please, any response any one can give me will be greatly
appreciated.
Sincerely,

Hello
I have a question
I am trying to send mail with mapi
I have configured my outlook express and I have an account called TestProfile there.
So I load up mapi like this:
<br />
<br />
LHANDLE session;<br />
MapiMessage *mes;<br />
MapiRecipDesc from;<br />
char messId[512],mname[50],maddr[30],fsubj[50];<br />
HINSTANCE hMAPI;<br />
<br />
<br />
ULONG (PASCAL FAR *mSendMail)(ULONG, ULONG, MapiMessage*, FLAGS, ULONG);<br />
ULONG (PASCAL FAR *mLogoff)(LHANDLE, ULONG, FLAGS, ULONG);<br />
ULONG (PASCAL FAR *mLogon)(ULONG, LPTSTR, LPTSTR, FLAGS, ULONG, LPLHANDLE);<br />
ULONG (PASCAL FAR *mFindNext)(LHANDLE, ULONG, LPTSTR, LPTSTR, FLAGS, ULONG, LPTSTR);<br />
ULONG (PASCAL FAR *mReadMail)(LHANDLE, ULONG, LPTSTR, FLAGS, ULONG, lpMapiMessage FAR *);<br />
ULONG (PASCAL FAR *mFreeBuffer)(LPVOID);<br />
<br />
<br />
hMAPI=LoadLibrary("MAPI32.DLL");<br />
if (hMAPI==NULL)<br />
{<br />
MessageBox(0,"nu exista MAPI.DLL ","ciudat",MB_OK);<br />
}<br />
(FARPROC &)mSendMail=GetProcAddress(hMAPI, "MAPISendMail");<br />
<br />
MessageBox(0,"am ajuns aici","a",MB_OK);<br />
<br />
(FARPROC &)mLogon=GetProcAddress(hMAPI, "MAPILogon");<br />
(FARPROC &)mLogoff=GetProcAddress(hMAPI, "MAPILogoff");<br />
(FARPROC &)mFindNext=GetProcAddress(hMAPI, "MAPIFindNext");<br />
(FARPROC &)mReadMail=GetProcAddress(hMAPI, "MAPIReadMail");<br />
(FARPROC &)mFreeBuffer=GetProcAddress(hMAPI, "MAPIFreeBuffer");<br />
<br />
<br />
if (mLogon==NULL)<br />
{<br />
MessageBox(0,"nu exista functia mlogon ","ciudat",MB_OK);<br />
}<br />
<br />
then I logon to mapi because I understand that you can't send mail if you don't correct me if I am wrong
<br />
<br />
ULONG a;<br />
<br />
a=mLogon(NULL,NULL,NULL,MAPI_NEW_SESSION ,NULL,&session);<br />
switch(a)<br />
{<br />
case MAPI_E_FAILURE:<br />
<br />
MessageBox(0,"One or more unspecified errors occurred during logon. No session handle was returned.","a",MB_OK); <br />
break;<br />
case MAPI_E_INSUFFICIENT_MEMORY: <br />
MessageBox(0,"There was insufficient memory to proceed. No session handle was returned. ","a",MB_OK);<br />
break;<br />
case MAPI_E_LOGIN_FAILURE:<br />
MessageBox(0,"There was no default logon, and the user failed to log on successfully when the logon dialog box was displayed. No session handle was returned. ","a",MB_OK);<br />
break;<br />
<br />
case MAPI_E_TOO_MANY_SESSIONS:<br />
MessageBox(0,"The user had too many sessions open simultaneously. No session handle was returned. ","a",MB_OK);<br />
break;<br />
case MAPI_E_USER_ABORT:<br />
<br />
MessageBox(0,"The user canceled the logon dialog box. No session handle was returned. ","a",MB_OK);<br />
break;<br />
case SUCCESS_SUCCESS:<br />
MessageBox(0,"a mers?!?","ciudat",MB_OK);<br />
break;<br />
<br />
default:<br />
{<br />
MessageBox(0,"m-am dat reaku ","ciudat",MB_OK);<br />
}<br />
<br />
}<br />
<br />
now here is the problem I always end up in the default wich means it is none of the above
This started after I made that outlook account TestProfile
I made it because I read a article on codeproject.com about mapi and it said that I should have one like that and I made one but I still can't send mail not even with the program from that article(compiled source code)
Before I did this MAPI used to log on but I never got to send any mail
It always prompted me if I wanted my mail to be send and I always said yes but I never got to send any mail.
Maby I did something wrong I don't know here is how tryed to send it:
<br />
<br />
mes->ulReserved=0;<br />
mes->lpszSubject=fsubj;<br />
mes->lpszNoteText="bla bla bal";<br />
mes->lpszMessageType=NULL;<br />
mes->lpszDateReceived=NULL;<br />
mes->lpszConversationID=NULL;<br />
mes->flFlags=MAPI_SENT;<br />
mes->lpOriginator->ulReserved=0;<br />
mes->lpOriginator->ulRecipClass=MAPI_ORIG;<br />
mes->lpOriginator->lpszName=mes->lpRecips->lpszName;<br />
mes->lpOriginator->lpszAddress=mes->lpRecips->lpszAddress;<br />
mes->nRecipCount=1;<br />
mes->lpRecips->ulReserved=0;<br />
mes->lpRecips->ulRecipClass=MAPI_TO;<br />
mes->lpRecips->lpszName=mname;<br />
mes->lpRecips->lpszAddress=maddr;<br />
mes->nFileCount=1;<br />
mes->lpFiles=(MapiFileDesc *)malloc(sizeof(MapiFileDesc));<br />
memset(mes->lpFiles, 0, sizeof(MapiFileDesc));<br />
mes->lpFiles->ulReserved=0;<br />
mes->lpFiles->flFlags=NULL;<br />
mes->lpFiles->nPosition=-1;<br />
mes->lpFiles->lpszPathName="D:\a.txt";<br />
mes->lpFiles->lpszFileName="a.txt";<br />
mes->lpFiles->lpFileType=NULL;<br />
mSendMail(session, NULL, mes, NULL, NULL);<br />
<br />
I am running win xp
please help out
thank you for your time
oh, and here is the name of that app I took from codeproject and it did not work for me to send mail with it :

Have you tried scaling the code down to something a wee bit smaller? What does the following produce:
HINSTANCE hMAPIInstance = LoadLibrary("MAPI32.DLL");
LPMAPILOGON lpMAPILogon = (LPMAPILOGON) GetProcAddress(hMAPIInstance, "MAPILogon");
LPMAPIRESOLVENAME lpMAPIResolveName = (LPMAPIRESOLVENAME) GetProcAddress(hMAPIInstance, "MAPIResolveName");
LPMAPISENDMAIL lpMAPISendMail = (LPMAPISENDMAIL) GetProcAddress(hMAPIInstance, "MAPISendMail");
LHANDLE lSession;
UINT uResult = (*lpMAPILogon)((UINT) m_hWnd, NULL, NULL, 0, 0, &lSession);
MapiRecipDesc *prMapiRecipient;
uResult = (*lpMAPIResolveName)(lSession, (UINT) m_hWnd, (LPSTR) lpszRecipient, 0, 0, prMapiRecipient);
lpMapiRecipDesc->ulReserved = 0;
lpMapiRecipDesc->ulRecipClass = MAPI_TO;
MapiMessage MapiMsg = {0};
MapiMsg.lpszSubject = (LPSTR) lpszSubject;
MapiMsg.lpszNoteText = (LPSTR) lpszBody;
MapiMsg.nRecipCount = 1;
MapiMsg.lpRecips = prMapiRecipient;
uResult = (*lpMAPISendMail)(lSession, (UINT) m_hWnd, &MapiMsg, 0, 0);

hey I scaled it down as much as I could
and it doesn't matter what that returns as long as mapi logon didn't work no?

I've been searching this topic for quite a while on
the codeproject, however, I can only find the similar
project using .Net in C# or VB.
I'm planning on writing an MP3 ripper, which can read
from CD ,then translate to MP3 format. But the key is,
I'm planning on Win 32 API, not .Net!! And it will be
written in C++.
If you do know a similar project elsewhere, or maybe
even on codeproject, please let me know. However, I
don't think there is one has been written, so you any
one of you who are looking for a topic to write, will you
please consider it?
Thanks.

Thanks for your reply. However, the link for

Thanks again.

i had a a question like this one i the past but I didn't get the answer I wanted;
I want to know how can I hook a windows function for example
int connect(
SOCKET s,
const struct sockaddr FAR *name,
int namelen
);
and replace it with a function of mine or something like this until I let the program call it like in a firewall.
please help me.

There are a few articles here on CodeProject dealing with API hooking.

i have a project which being planed to pretent API HOOK by other programs.
